Description

Poewr control method, access point apparatus and end-station device

Technical field

The embodiment of the present invention relates to wireless communication technology, particularly relates to Poewr control method, access point (Access Point is called for short AP) equipment and point of termination station (Station is called for short STA) equipment.

Background technology

For multiple-input, multiple-output (MultiDle-Input MultiDle-Output, be called for short MIMO) wireless communication system, at a transmission opportunity (Transmit Opportunity, be called for short TXOP) in, be not that all STA equipment in a basic service sets (Basic Service Set, be called for short BSS) all need to receive data.Therefore, adopt Poewr control method in a wireless communication system, allow does not have the STA equipment of data receiver to enter sleep state in current TXOP.Be in the receiver that dormant STA equipment closes self, thus reduce power consumption.

At present, the Poewr control method of wireless communication system is: AP equipment is to STA equipment transmit operation object identity and forbid that TXOP power saves instruction (No TXOP Power Save indicates, and is called for short No TXOP PS instruction).This operated object mark is used to indicate the one or more STA equipment needing to carry out operating.This forbids that TXOP power saves instruction can for being or no, wherein, is designated as no, then represents and allow the STA equipment in this BSS to carry out power save operation at current TXOP if forbid that TXOP power is saved; If forbidding that TXOP power saves to be designated as is then represent and forbid that the STA equipment in this BSS carries out power save operation at current TXOP.This forbids that the valid interval that TXOP power is saved indicated by instruction is current TXOP, and therefore, if STA equipment enters sleep state, then this STA equipment is by maintenance sleep state until this TXOP terminates, and at the end of this TXOP, STA equipment returns to waking state.AP equipment indicates STA equipment by sending the frame comprising operated object mark, and when forbidding that TXOP power saving is designated as no, according to operated object mark and sleep condition, STA equipment judges whether self enters sleep state.For multiuser MIMO (Multi-User MIMO is called for short MU-MIMO) pattern, STA equipment can judge according to multinomial sleep condition, as long as meet one of them can enter sleep state; When above-mentioned multinomial sleep condition does not all meet, be judged as not meeting sleep condition, STA equipment keeps waking state.And, under MU-MIMO pattern, at each frame, AP equipment also have sent spatial reuse fluxion instruction (being called Nsts territory) of each user of MU-MIMO to STA equipment, notifies the number of its corresponding spatial reuse stream for the multiple STA indicated by operated object mark.Particularly, above-mentioned multinomial sleep condition specifically comprises following three conditions.Condition one: when not comprising the instruction to this STA equipment in the operated object mark of default frame, STA equipment enters sleep state.Condition two: when the operated object mark of default frame comprises the instruction to this STA equipment, and when spatial reuse fluxion corresponding to this STA is designated as 0, STA equipment enters sleep state.Condition three: when the operated object mark of default frame comprises the instruction to this STA equipment, and this STA receives more data bit when being designated as the Frame of 0, and STA equipment enters sleep state.Operand of the prior art is expressed as group mark (Group Identity is called for short Group ID).In practical wireless communication systems, the situation that frequent existence group is multiplexing, that is: the Group ID of each frame can indicate multiple groups, and each group of STA equipment comprised is different.Therefore, Group ID indicate multiple groups in the STA equipment included by any two groups different.Such as, the Group ID of a frame indicates 2 groups, represents the Group ID of this frame with Group ID A, and represent above-mentioned 2 groups to organize 1 respectively with group 2, then, when a frame needs instruction group 1 or need instruction group 2, the Group ID of this frame is Group ID A.Wherein, the STA that comprises of first, second, third and fourth position of 1 is organized respectively: the first STA equipment, the second STA equipment, Three S's TA equipment and the 4th STA equipment; The STA that comprises of first, second, third and fourth position of group 2 is respectively: the 5th STA equipment, the 6th STA equipment, the 7th STA equipment and the 8th STA equipment.The instruction of spatial reuse fluxion is used for indicating the spatial reuse fluxion of the STA equipment of correspondence position, when employing group is multiplexing, if the spatial reuse fluxion of certain position is designated as 0, then represent that the spatial reuse fluxion of the STA equipment of the correspondence position in all groups indicated by this Group ID is 0.Such as, if the fluxion needing the STA equipment indicating said second position at the kth frame of a TXOP is 0, then the Group ID of this frame is: Group ID A, and spatial reuse fluxion is designated as: in group, the spatial reuse fluxion of the 2nd STA equipment is designated as 0.According to the condition two in the instruction of kth frame and above-mentioned multinomial sleep condition, then the second STA equipment organized in 1 can enter sleep state, but because employing group is multiplexing, then the 6th STA equipment organizing 2 also can enter sleep state simultaneously.If need to carry out information interaction with the 6th STA equipment at kth+1 frame, because the 6th STA equipment enters sleep state, then cannot receive packet, therefore lead to errors, communication process cannot correctly complete.

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

In existing Poewr control method, AP equipment comprises to each frame that SAT equipment sends and forbids that TXOP power saves instruction, operated object mark and Media Access Control Address (Medium Access Control Address is called for short MAC Address).Under MU-MIMO pattern, the frame that AP sends comprises the packet header sent by VHT-SIG-A signaling, and the data flow of each STA of correspondence sent by MU-MIMO spatial multiplexing mode after packet header.Wherein, packet header comprises the fluxion information of each STA in operated object mark and group.Under MU-MIMO pattern, operated object mark is Group ID.Data flow comprises each data flow corresponding to each STA non-zero with fluxion, and this data flow comprises the MAC Address of corresponding STA equipment.Particularly, AP is by the data flow of several spatial reuses corresponding to STA, and send at least one mac frame to this STA equipment, the frame head of this mac frame comprises the receiving terminal mac address information of 6 bytes.STA equipment is decoded to this receiving terminal mac address information, contrasts with the MAC Address of STA equipment self, if identical, illustrate that this mac frame issues oneself, then decodes to this frame; If different, illustrate that this mac frame does not issue oneself, then it is not decoded.

In embodiments of the present invention, add follow-up STA in each frame and indicate and organize the instruction of multiplexing relevant sleep.Wherein, follow-up STA instruction is used to indicate in the later frame of present frame the STA equipment do not indicated the multiple frames whether existed from the first frame to present frame; Organize the instruction of multiplexing relevant sleep to be used to indicate and whether to allow the operated object mark by the end of multiple frames of present frame to indicate and STA equipment that MAC Address did not indicate enters sleep state.Below of the present invention, each is in example, and operated object mark is Group ID.

Fig. 1 is the flow chart of the Poewr control method of the embodiment of the present invention one.In the embodiment of the present invention one, for the operating process of AP equipment, this Poewr control method is described, and to forbid that TXOP power is saved instruction and is always no.As shown in Figure 1, the method comprises following process.

Step 101:AP equipment sends default frame corresponding to the present frame of current TXOP to STA equipment.Wherein, for present frame and default frame, each frame comprises: operated object mark, MAC Address, follow-up STA indicate and organize the instruction of multiplexing relevant sleep.

At present frame, each STA equipment judges according to sleep condition, to determine that can oneself enter sleep state at present frame.If this STA judges that oneself can enter sleep state at present frame, then this STA can enter sleep state until this TXOP terminates; Or this STA can send confirmation of receipt (Acknowledge the is called for short ACK) signal for present frame, then enters sleep state until this TXOP terminates.At present frame, each STA judges that can the sleep condition that oneself enter sleep state institute foundation be: the STA set indicated by the Group ID of default frame corresponding to present frame do not comprise this STA equipment and follow-up STA be designated as follow-up nothing increase STA newly time, or, STA indicated by the Group ID set of the default frame that above-mentioned present frame is corresponding comprise this STA equipment and the MAC Address of default frame corresponding to above-mentioned present frame do not comprise this STA equipment and the multiplexing relevant sleep of the group of present frame is designated as permission time, this STA equipment can enter sleep state.

In this step, the set-up mode of the follow-up STA instruction of present frame is as follows.If the set of the STA indicated by Group ID of the default frame that the present frame of current TXOP is corresponding comprises the STA equipment of the later all frames of current TXOP present frame, then the follow-up STA instruction of present frame can be set to follow-up nothing and increase STA newly.If the set of the STA indicated by Group ID of the default frame that the present frame of current TXOP is corresponding does not comprise the STA equipment of the later all frames of current TXOP present frame completely, namely AP equipment also can give the data of other STA equipment transmission beyond STA equipment indicated by above-mentioned default frame in subsequent frames, then the follow-up STA instruction of present frame must be set to follow-uply have newly-increased STA.

In this step, the set-up mode of the group of present frame multiplexing relevant sleep instruction is as follows.If in the STA set indicated by the Group ID of default frame corresponding to above-mentioned present frame, the STA equipment that the MAC Address of the default frame that above-mentioned present frame is corresponding had not indicated, in all frames after current TXOP present frame, AP equipment all can not transmit data to it, then the multiplexing relevant sleep instruction of the group of present frame can be set to allow or forbid.If in the STA set indicated by the Group ID of default frame corresponding to above-mentioned present frame, at least one in the STA equipment that the MAC Address of the default frame that above-mentioned present frame is corresponding had not indicated, in at least one frame in all frames after current TXOP present frame, AP equipment can transmit data to it, then the multiplexing relevant sleep instruction of the group of present frame must be set to forbid.That is, if all frames after current TXOP present frame, AP equipment all can not transmit data and once indicate to the Group ID of default frame corresponding to present frame and the STA equipment that do not indicated of the MAC Address of default frame corresponding to present frame, then AP can be set to permission multiplexing for group relevant sleep instruction; And if at least one frame in all frames after current TXOP present frame, AP equipment can transmit data and once indicate to the Group ID of default frame corresponding to present frame and at least one STA equipment in all STA equipment of not indicated of the MAC Address of default frame corresponding to present frame, then the multiplexing relevant sleep instruction of the group of present frame must be set to forbid.

In the embodiment of the present invention one, the default frame that above-mentioned present frame is corresponding comprises two kinds of embodiments.In a first embodiment, the default frame that above-mentioned present frame is corresponding comprises: the present frame of current TXOP.In the second execution mode, the default frame that above-mentioned present frame is corresponding comprises: first frame of current TXOP is to the one or more frame of present frame.

In the embodiment of the present invention one, AP equipment not only sends operated object mark and the MAC Address of each frame, and send the follow-up STA instruction of each frame and organize the instruction of multiplexing relevant sleep, judge whether to enter sleep state according to above-mentioned 4 to make STA equipment, when operated object mark does not comprise this STA equipment and follow-up nothing increases STA newly, or, when operated object mark comprise this STA equipment and MAC Address do not comprise this STA equipment and organize multiplexing relevant sleep be designated as permission time, this STA equipment can enter sleep state.Thus when employing group is multiplexing, can the STA equipment do not indicated the Group ID of above-mentioned default frame and the Group ID of above-mentioned default frame once indicate and STA equipment that MAC Address had not indicated, respectively adopt a bit instruction enter sleep state at present frame respectively.In the embodiment of the present invention one, sleep state can be entered to each STA equipment accurately to distinguish, improve the effect that power is saved, avoid simultaneously and judge mistake owing to organizing the multiplexing STA equipment that causes to sleeping, thus improve the correctness of power saving.

Fig. 2 is the flow chart of the Poewr control method of the embodiment of the present invention two.In the embodiment of the present invention two, for the operating process of STA equipment, this Poewr control method is described, and to forbid that TXOP power is saved instruction and is always no.As shown in Figure 2, the method comprises following process.

Step 201:STA equipment obtains default frame corresponding to current TXOP present frame.Wherein, for present frame and default frame, each default frame comprises: operated object mark, MAC Address, follow-up STA indicate and organize the instruction of multiplexing relevant sleep.

Step 202: when the operated object mark of default frame corresponding to above-mentioned present frame do not comprise this STA equipment and the follow-up STA of present frame be designated as follow-up nothing increase STA newly time, this STA equipment can enter sleep state at present frame; When the operated object mark of default frame corresponding to above-mentioned present frame comprise this STA equipment and the MAC Address of default frame corresponding to above-mentioned present frame do not comprise this STA equipment and the multiplexing relevant sleep of the group of present frame is designated as permission time, this STA equipment can enter sleep state at present frame.

In this step, if a STA equipment can enter sleep state at present frame, then it both can enter sleep state, to save power, also can keep waking state.And if a STA equipment does not obtain entering dormant license at present frame, then it must keep waking state at present frame, until the next frame of present frame, then judges whether to enter sleep state at this frame.

On the basis of technique scheme, further, if the operated object mark of the default frame that present frame is corresponding comprises this STA equipment and the MAC Address of default frame corresponding to present frame comprises this STA equipment and this STA equipment receives the Frame that more data bit is 0, this STA equipment can enter sleep state.

In the embodiment of the present invention two, the default frame that above-mentioned present frame is corresponding comprises two kinds of embodiments.In a first embodiment, the default frame that above-mentioned present frame is corresponding comprises: the present frame of current TXOP.In the second execution mode, the default frame that above-mentioned present frame is corresponding comprises: first frame of current TXOP is to the one or more frame of present frame.

In the embodiment of the present invention two, STA equipment not only obtains operated object mark and the MAC Address of each frame, and obtain the follow-up STA instruction of each frame and organize the instruction of multiplexing relevant sleep, judge whether to enter sleep state according to above-mentioned 4, when operated object mark does not comprise this STA equipment and follow-up nothing increases STA newly, or, when operated object mark comprise this STA equipment and MAC Address do not comprise this STA equipment and sleep be designated as permission time, this STA equipment can enter sleep state, thus each STA equipment time multiplexing to employing group is accurately distinguished, avoid and judge mistake owing to organizing the multiplexing STA equipment that causes to sleeping, thus improve the correctness of power saving.

Fig. 3 is the flow chart of the Poewr control method of the embodiment of the present invention three.In the embodiment of the present invention three, for AP equipment and the crew-served flow process of STA equipment, and to forbid that TXOP power saving instruction is always no and is described.In the embodiment of the present invention three, adopt 1 bit to represent that follow-up STA indicates, and adopt 1 multiplexing relevant sleep instruction of bit expression group.As shown in Figure 3, the method comprises following process.

Step 301:AP equipment sends default frame corresponding to the present frame of current TXOP to STA equipment.Wherein, for present frame and default frame, each frame comprises: operated object mark, MAC Address, follow-up STA indicate and organize the instruction of multiplexing relevant sleep.

In this step, AP equipment indicated and organized the instruction of multiplexing relevant sleep set-up mode to follow-up STA is identical with step 101, does not repeat them here.

Step 302:STA equipment obtains default frame corresponding to the present frame of current TXOP.Wherein, for present frame and default frame, each frame comprises: operated object mark, MAC Address, follow-up STA indicate and organize the instruction of multiplexing relevant sleep.

In this step 301 and step 302, follow-up STA instruction comprises 1 bit, is called follow-up STA indication bit.The set-up mode that AP equipment indicates follow-up STA is identical with step 101.If the STA equipment involved by all frames of current TXOP all indicates in default frame, preset in the subsequent frame after frame and there is not newly-increased STA equipment, then follow-up STA instruction can be set to follow-up nothing and increase STA newly, and this bit is the first value.If the STA equipment involved by all frames of current TXOP is not all included in default frame, presets in the subsequent frame after frame and also there will be newly-increased STA equipment, then follow-up STA instruction must be set to follow-uply have newly-increased STA, and this bit is the second value.One preferably execution mode is, when follow-up nothing increases STA newly, the first value of this bit is 1; When follow-up have a newly-increased STA time, the second value of this bit is 0.

Further, in step 301 and step 302, organize the instruction of multiplexing relevant sleep and comprise 1 bit, be called the multiplexing relevant sleep indication bit of group.The set-up mode of AP equipment to the instruction of group multiplexing relevant sleep is identical with step 101.For the STA equipment in the operated object mark being included in above-mentioned default frame and not included in the MAC Address of above-mentioned default frame, if allow it to sleep, this bit is the first value; If forbid that it is slept, this bit is the second value.One preferably execution mode is, when allowing above-mentioned STA equipment to sleep, the first value of this bit is 1; When forbidding that above-mentioned STA equipment is slept, the second value of this bit is 0.

Step 303:STA equipment judges whether the operated object mark of the default frame that above-mentioned present frame is corresponding comprises this STA equipment, if so, performs step 312; Otherwise, perform step 311.

Step 311:STA equipment judges that the follow-up STA indication bit of present frame is the first value or the second value, if be the first value, then this STA equipment can enter sleep state; If be the second value, then this STA equipment keeps waking state.

Step 312:STA equipment judges whether the MAC Address of the default frame that above-mentioned present frame is corresponding comprises this STA equipment, if so, performs step 322; Otherwise, perform step 321.

Step 321:STA equipment judges that the multiplexing relevant sleep indication bit of the group of present frame is the first value or the second value, if be the first value, then this STA equipment can enter sleep state, if be the second value, then this STA equipment keeps waking state.

Step 322:STA equipment judges whether to receive the Frame that more data bit is 0, and if so, then this STA equipment can enter sleep state, otherwise this STA equipment keeps waking state.

In the embodiment of the present invention three, the default frame that above-mentioned present frame is corresponding comprises two kinds of embodiments.In a first embodiment, the default frame that above-mentioned present frame is corresponding comprises: the present frame of current TXOP.In the second execution mode, the default frame that above-mentioned present frame is corresponding comprises: first frame of current TXOP is to the one or more frame of present frame.

Fig. 5 is the flow chart of the Poewr control method of the embodiment of the present invention five.In the embodiment of the present invention five, for AP equipment and the crew-served flow process of STA equipment.In the embodiment of the present invention five, to in TXOP frame in prior art forbid TXOP power save instruction improve, by above-mentioned follow-up STA and group multiplexing relevant sleep indication bit and forbid that TXOP power is saved instruction and combined, only adopt 1 bit to represent follow-up STA indicates, organize the instruction of multiplexing relevant sleep and forbid TXOP power saving instruction simultaneously, and this bit is called that TXOP power saves comprehensive indication bit.In the embodiment of the present invention five, simple in order to what state, forbid that TXOP power is saved instruction and is expressed as TXOP power saving instruction of the prior art, TXOP power saves the situation being designated as permission, saving that to be designated as no situation identical with forbidding TXOP power, representing and allowing to carry out power saving in this TXOP; TXOP power is saved and is designated as the situation of forbidding, saves that to be designated as the situation being identical with forbidding TXOP power, expression is forbidden carrying out power saving in this TXOP.As shown in Figure 5, the method comprises following process.

Step 501:AP equipment sends default frame corresponding to the present frame of current TXOP to STA equipment.Wherein, for present frame and default frame, each frame comprises: TXOP power saves comprehensive indication bit, operated object mark, MAC Address.

In this step, to save the set-up mode of comprehensive indication bit as follows for the TXOP power of AP equipment to present frame.At present frame, AP equipment judges whether satisfied following three conditions.First condition is: allow to carry out TXOP power saving at present frame.Second condition and the 3rd condition respectively at record in step 401 to arrange follow-up STA identical with two conditions when organizing multiplexing relevant sleep indication bit.If at present frame, above-mentioned 3 conditions are all satisfied, then AP equipment can the TXOP power of present frame save comprehensive indication bit be set to be, represent and allow TXOP power to save, follow-up nothing increases STA newly, and to allow to be included in the operated object mark of above-mentioned default frame and STA equipment sleep not included in the MAC Address of above-mentioned default frame.If at present frame, at least one in above-mentioned 3 Rule of judgment is false, then AP must save comprehensive indication bit the TXOP power of present frame and is set to no, representing does not allow TXOP power to save, or follow-uply have newly-increased STA, or the STA equipment sleep in the operated object mark not allowing to be included in above-mentioned default frame and not included in the MAC Address of above-mentioned default frame.

Step 502:STA equipment obtains default frame corresponding to the present frame of current TXOP.Wherein, for present frame and default frame, each frame comprises: TXOP power saves comprehensive indication bit, operated object mark, MAC Address.

In step 501 with step 502, TXOP power saves instruction, follow-up STA indicates and organize the instruction of multiplexing relevant sleep only to adopt 1 bit to represent, that is, above-mentioned 3 instructions comprise 1 bit altogether, and this bit is called that TXOP power saves comprehensive indication bit.At present frame, only have and allow TXOP power to save instruction, and follow-up nothing increases STA newly, and to allow to be included in the operated object mark of above-mentioned default frame and STA equipment sleep not included in the MAC Address of above-mentioned default frame time, this bit can be the first value, represents and allows sleep.Otherwise at present frame, when forbidding that TXOP power is saved, this bit being necessary for the second value, representing and forbidding sleep.When follow-up have a newly-increased STA time, this bit is necessary for the second value, represents and forbids sleep.When STA equipment sleep in the operated object mark not allowing to be included in above-mentioned default frame and not included in the MAC Address of above-mentioned default frame, this bit is necessary for the second value, represents and forbids sleep.One preferably execution mode is, the first value of this bit is 1; Second value of this bit is 0.

Step 503:STA equipment judges that the above-mentioned group of comprehensive indication bit of multiplexing relevant sleep is the first value or the second value, if be the first value, performs step 504; If be the second value, STA equipment keeps waking state.

Step 504:STA equipment judges whether satisfied comprehensive sleep condition, and if so, STA equipment can enter sleep state; Otherwise STA equipment keeps waking state.

In this step, comprehensive sleep condition specifically comprises following four conditions, when meet wherein at least one time, STA equipment judge meet comprehensive sleep condition at present frame.Particularly, condition one: when not comprising the instruction to this STA equipment in the operated object mark of default frame corresponding to present frame, STA equipment can enter sleep state.Condition two: when the operated object mark of default frame corresponding to present frame comprises the instruction to this STA equipment, and when spatial reuse fluxion corresponding to this STA is designated as 0, STA equipment can enter sleep state.Condition three: when the operated object mark of default frame corresponding to present frame comprises the instruction to this STA equipment, and this STA receives more data bit when being designated as the Frame of 0, and STA equipment can enter sleep state.Condition four: the operated object mark of the default frame that present frame is corresponding comprises the instruction to this STA equipment, and in the MAC Address of default frame corresponding to present frame, do not comprise the instruction to this STA equipment, STA equipment can enter sleep state.

In the embodiment of the present invention five, the default frame that above-mentioned present frame is corresponding comprises two kinds of embodiments.In a first embodiment, the default frame that above-mentioned present frame is corresponding comprises: the present frame of current TXOP.In the second execution mode, the default frame that above-mentioned present frame is corresponding comprises: first frame of current TXOP is to the one or more frame of present frame.

In the embodiment of the present invention five, 1 bit is adopted to represent altogether to forbidding that TXOP power saving instruction, follow-up STA instruction and the multiplexing relevant sleep of group indicate, only have when allow this TXOP carry out power saving and follow-up nothing increase STA newly and to allow to be included in the operated object mark of above-mentioned default frame and STA equipment sleep not included in the MAC Address of above-mentioned default frame time, this bit can allow to enter dormant first value for expression, STA equipment, when this bit is for allowing, judges whether to enter sleep state according to comprehensive sleep condition.Thus avoid and judge mistake owing to organizing the multiplexing STA equipment that causes to sleeping, improve the correctness that power is saved.

In existing Poewr control method, when employing group is multiplexing, STA equipment enters sleep state when spatial reuse fluxion is designated as 0 and likely causes garble.In embodiments of the present invention, add fluxion 0 user in each frame to sleep instruction, when more than one STA equipment corresponding to position that in more than one group only having the operated object mark when this frame to indicate, space multiplex stream number is designated as 0 does not all have data to need to receive in subsequent frames, this fluxion 0 user instruction of sleeping just can be set to allow.

Fig. 6 is the flow chart of the Poewr control method of the embodiment of the present invention six.In the embodiment of the present invention six, for the operating process of AP equipment, this Poewr control method is described, and to forbid that TXOP power is saved instruction and is always no.As shown in Figure 6, the method comprises following process.

Step 601:AP equipment sends the one or more frame of current TXOP to STA equipment.Wherein, each frame comprises: operated object mark, instruction that spatial reuse fluxion indicates and fluxion 0 user sleeps.

In this step, following principle is followed in the sleep setting of instruction of fluxion 0 user of AP equipment to each frame: when more than one STA equipment corresponding to position that space multiplex stream number in more than one group that the operated object mark of this frame indicate is designated as 0 does not have data to need reception in subsequent frames, and fluxion 0 user of this frame instruction of sleeping can be set to permission; When at least one STA equipment be designated as in one or more STA equipment corresponding to position of 0 of space multiplex stream number in more than one group that the operated object mark of this frame indicates has data to need to receive in subsequent frames, fluxion 0 user of this frame instruction of sleeping must be set to and forbids.

AP equipment comprises operated object mark, the instruction of spatial reuse fluxion to the frame that STA equipment sends and to sleep instruction according to fluxion 0 user that mentioned above principle is arranged.If fluxion 0 user sleep is designated as permission, then the STA equipment indicated by operated object mark of an above-mentioned frame, when finding that spatial reuse fluxion corresponding to this STA equipment is designated as 0, just sleep state can be entered; And if fluxion 0 user sleep is designated as and does not allow, then the STA equipment indicated by operated object mark of an above-mentioned frame, when finding that spatial reuse fluxion corresponding to this STA equipment is designated as 0, cannot enter sleep state, and must keep waking state.

On the basis of technique scheme, further, above-mentioned fluxion 0 user instruction of sleeping can comprise 1 bit, and also can comprise more than one bit, above-mentioned bit is called enable bit.

When fluxion 0 user sleep instruction comprise 1 bit time, adopt this 1 bit instruction spatial reuse fluxion to be designated as all positions of 0.When fluxion 0 user sleep instruction comprise 1 bit: if more than one STA equipment corresponding to position that all spatial reuse fluxions in more than one group of operated object mark instruction are designated as 0 does not all have data to need to receive in subsequent frames, then this bit is the first value, represent for spatial reuse fluxion be designated as all positions of 0 fluxion 0 user sleep be designated as permission.If one or more spatial reuse fluxions at least one STA equipment be designated as in one or more STA equipment corresponding to position of 0 in more than one group of operated object mark instruction has data to need to receive in subsequent frames, then this bit is the second value, represents that the fluxion 0 user sleep being designated as all positions of 0 for spatial reuse fluxion is designated as and forbids.

When fluxion 0 user sleep instruction comprise more than one bit time, this more than one bit and spatial reuse fluxion are designated as more than one the position one_to_one corresponding of 0, that is, adopt each bit to indicate separately spatial reuse fluxion to be designated as each position of 0.Fluxion 0 user sleeps instruction when comprising more than one bit: if more than one STA equipment corresponding to position that a spatial reuse fluxion in more than one group of operated object mark instruction is designated as 0 countlessly in subsequent frames receives according to needs, then this spatial reuse fluxion is designated as a bit corresponding to position of 0 is the first value, represents that the fluxion 0 user sleep being designated as the position of 0 for this spatial reuse fluxion is designated as permission.If a spatial reuse fluxion at least one STA equipment be designated as in one or more STA equipment corresponding to position of 0 in more than one group of operated object mark instruction has data to need to receive in subsequent frames, then this spatial reuse fluxion is designated as a bit corresponding to position of 0 is the second value, represents that the fluxion 0 user sleep being designated as the position of 0 for this spatial reuse fluxion is designated as and forbids.Particularly, in actual applications, the position that spatial reuse fluxion is designated as 0 comprises at most 3, then the 1st spatial reuse fluxion is designated as corresponding 1st bit in position of 0,2nd spatial reuse fluxion is designated as corresponding 2nd bit in position of 0, and the 3rd spatial reuse fluxion is designated as corresponding 3rd bit in position of 0.Under normal circumstances, the position that spatial reuse fluxion is designated as 0 is 2, therefore, one preferably execution mode is, fluxion 0 user instruction of sleeping comprises 2 bits, 1st spatial reuse fluxion is designated as corresponding 1st bit in position of 0, and the 2nd spatial reuse fluxion is designated as corresponding 2nd bit in position of 0.

Fig. 7 is the flow chart of the Poewr control method of the embodiment of the present invention seven.In the embodiment of the present invention seven, for the operating process of STA equipment, this Poewr control method is described, and to forbid that TXOP power is saved instruction and is always no.As shown in Figure 7, the method comprises following process.

Step 701:STA equipment obtains the one or more frame of current TXOP.Wherein, each frame comprises: operated object mark, instruction that spatial reuse fluxion indicates and fluxion 0 user sleeps.

Step 702: when the operated object mark of present frame comprises this STA equipment, and fluxion 0 user of present frame sleep is designated as permission, and when spatial reuse fluxion corresponding to this STA equipment is designated as 0, then this STA equipment can enter sleep state at present frame.

Further, in a step 702, when meeting the situation described in step 702, STA equipment can be selected to enter sleep state, also can select to keep waking state.When not meeting the situation described in step 702, STA equipment must keep waking state.

When fluxion 0 user sleep instruction comprise 1 bit, the value of this bit is that AP equipment is arranged according to following principle: if more than one STA equipment corresponding to position that all spatial reuse fluxions in more than one group of operated object mark instruction are designated as 0 does not all have data to need to receive in subsequent frames, then this bit can be set to the first value, represent for spatial reuse fluxion be designated as all positions of 0 fluxion 0 user sleep be designated as permission.If one or more spatial reuse fluxions at least one STA equipment be designated as in one or more STA equipment corresponding to position of 0 in more than one group of operated object mark instruction has data to need to receive in subsequent frames, then this bit must be set to the second value, represents that the fluxion 0 user sleep being designated as all positions of 0 for spatial reuse fluxion is designated as and forbids.STA equipment is after the above-mentioned frame of acquisition, and when the operated object mark of above-mentioned frame comprises this STA equipment, and this bit is the first value, and when spatial reuse fluxion corresponding to this STA equipment is designated as 0, this STA equipment can enter sleep state; Otherwise this STA equipment must keep waking state.

When fluxion 0 user sleep instruction comprise more than one bit, the value of this bit is that AP equipment is arranged according to following principle: if more than one STA equipment corresponding to position that a spatial reuse fluxion in more than one group of operated object mark instruction is designated as 0 countlessly in subsequent frames receives according to needs, a bit corresponding to position that then this spatial reuse fluxion is designated as 0 can be set to the first value, represents that the fluxion 0 user sleep being designated as the position of 0 for this spatial reuse fluxion is designated as permission.If one or more STA equipment corresponding to position that a spatial reuse fluxion in more than one group of operated object mark instruction is designated as 0 have data to need to receive in subsequent frames, then this spatial reuse fluxion is designated as a bit corresponding to position of 0 is the second value, represents that the fluxion 0 user sleep being designated as the position of 0 for this spatial reuse fluxion is designated as and forbids.STA equipment is after the above-mentioned frame of acquisition, when the operated object mark of frame comprises this STA equipment, and bit corresponding to spatial reuse fluxion instruction corresponding to this STA equipment is the first value, and when spatial reuse fluxion corresponding to this STA equipment is designated as 0, this STA equipment can enter sleep state; Otherwise this STA equipment must keep waking state.

In the embodiment of the present invention six and the embodiment of the present invention seven, AP equipment adds fluxion 0 user in each frame and to sleep instruction, when more than one STA equipment corresponding to position that in more than one group only having the operated object mark when this frame to indicate, space multiplex stream number is designated as 0 does not all have data to need to receive in subsequent frames, this fluxion 0 user sleep is designated as permission, STA equipment judges according to this fluxion 0 user instruction of sleeping, the operated object mark when the above-mentioned frame obtained is only had to comprise this STA equipment, and fluxion 0 user sleep is designated as permission, and spatial reuse fluxion corresponding to this STA equipment is when being designated as 0, this STA equipment can enter sleep state.Avoid the multiplexing STA equipment caused of employing group and judge mistake to sleeping, thus improve the correctness of power saving.

Fig. 8 is the flow chart of the Poewr control method of the embodiment of the present invention eight.In the embodiment of the present invention eight, for AP equipment and the crew-served flow process of STA equipment.In the embodiment of the present invention eight, to in TXOP frame in prior art forbid TXOP power save instruction improve, above-mentioned fluxion 0 user is slept and indicates and forbid that TXOP power is saved instruction and combined, only adopt 1 bit to represent fluxion 0 user sleeps instruction and forbid that TXOP power saves instruction, is called that TXOP power saves synthesis indication bit simultaneously.In the embodiment of the present invention eight, clear in order to what express, with TXOP power save instruction expression way substitute of the prior art forbid TXOP power save instruction, TXOP power saves the situation being designated as permission, saving that to be designated as no situation identical with forbidding TXOP power, representing and allowing to carry out power saving in this TXOP; TXOP power is saved and is designated as the situation of forbidding, saves that to be designated as the situation being identical with forbidding TXOP power, expression is forbidden carrying out power saving in this TXOP.As shown in Figure 8, the method comprises following process.

Step 801:AP equipment sends default frame corresponding to the present frame of current TXOP to STA equipment.Wherein, for present frame and default frame, each frame comprises: operated object mark, and the instruction of spatial reuse fluxion and TXOP power save synthesis indication bit.

In this step, at present frame, AP device for flow number 0 user sleep instruction set-up mode as follows.At present frame, AP equipment judges whether satisfied following two conditions.First condition is: allow each STA equipment to carry out TXOP power saving at present frame.Second condition is: more than one STA equipment corresponding to position that in more than one group of the operated object mark of present frame instruction, space multiplex stream number is designated as 0 does not have data to need to receive in subsequent frames.If at present frame, above two conditions are all satisfied, then AP equipment can be saved synthesis indication bit the TXOP power of present frame and be set to permission, if at least one in above two conditions is false, then AP equipment must be set to TXOP power saving synthesis indication bit not allow.

Step 802:STA equipment obtains default frame corresponding to the present frame of current TXOP.Wherein, for present frame and default frame, each frame comprises: the instruction of operated object mark, spatial reuse fluxion and TXOP power save synthesis indication bit.

In step 801 and step 802, TXOP power is saved instruction and fluxion 0 user and to be slept instruction only to adopt 1 bit to represent, that is, above-mentioned 2 instructions comprise 1 bit altogether, and this bit is called that indication bit is synthesized in TXOP power saving.Only have and allow to do TXOP power saving at present frame, and when allowing fluxion 0 user to sleep, this bit of this present frame can be the first value, represents and allows sleep.Otherwise whether, when forbidding that TXOP power is saved, no matter allow fluxion 0 user to sleep, this bit of this present frame being the second value, representing and forbidding sleep.Whether when forbidding that fluxion 0 user sleeps, no matter allow TXOP power to save, this bit of this present frame, represent and forbid sleep if being the second value.One preferably execution mode is, the first value of this bit is 1; Second value of this bit is 0.

It is the first value or the second value that step 803:STA equipment judges that above-mentioned TXOP power saves synthesis indication bit, if be the first value, performs step 804; If be the second value, STA equipment keeps waking state.

Step 804:STA equipment judges whether satisfied comprehensive sleep condition, and if so, STA equipment can enter sleep state; Otherwise STA equipment keeps waking state.

In this step, comprehensive sleep condition specifically comprises following three conditions, when meet wherein at least one time, STA equipment judge meet comprehensive sleep condition.Particularly, condition one: when not comprising the instruction to this STA equipment in the operated object mark of default frame corresponding to present frame, STA equipment can enter sleep state.Condition two: when the operated object mark of present frame comprises the instruction to this STA equipment, and when spatial reuse fluxion corresponding to this STA is designated as 0, STA equipment can enter sleep state.Condition three: when the operated object mark of default frame corresponding to present frame comprises the instruction to this STA equipment, and this STA receives more data bit when being designated as the Frame of 0, and STA equipment can enter sleep state.

On the basis of technique scheme, when adopting above-mentioned condition two to judge, the execution mode of optimization is: when TXOP power saves synthesis indication bit for allowing, and once receives the STA equipment that spatial reuse fluxion is designated as 0 and all can enter sleep state.Particularly, STA equipment carries out record when spatial reuse fluxion is designated as 0, and in each frame thereafter, once receive TXOP power to save synthesis indication bit for allowing, then this STA can enter sleep state.

In the embodiment of the present invention eight, above-mentioned default frame comprises two kinds of embodiments.In a first embodiment, above-mentioned default frame comprises: the present frame of current TXOP.In the second execution mode, above-mentioned default frame comprises: first frame of current TXOP is to the one or more frame of present frame.

In the embodiment of the present invention eight, 1 bit is adopted to represent altogether to forbidding that TXOP power saving instruction and fluxion 0 user sleep to indicate, only have when allowing when this TXOP carries out power saving and fluxion 0 user sleep is designated as permission, this bit can allow to enter dormant first value for expression, STA equipment, when this bit is for allowing, judges whether to enter sleep state according to comprehensive sleep condition.Thus avoid and judge mistake owing to organizing the multiplexing STA equipment that causes to sleeping, improve the correctness that power is saved.

In the embodiment of the present invention five and embodiment eight, all only adopt 1 bit to indicate multiple condition, particularly, in embodiment five, adopt 1 TXOP power to save comprehensive indication bit, in embodiment eight, adopt 1 TXOP power to save synthesis indication bit.In the technique scheme that the embodiment of the present invention five and embodiment eight are recorded, in each frame of a TXOP, the value that TXOP power saves comprehensive indication bit or TXOP power saving synthesis indication bit can change repeatedly.

For embodiments of the invention five, the default frame corresponding when present frame is when the current frame, and at each frame of a TXOP, the value that TXOP power saves comprehensive indication bit can change repeatedly, such as at the 1st, 2,3,4 of TXOP, 5,6,7,8 frames, this bit can set gradually as not allowing, and allows, do not allow, allow, do not allow, allow, allow, allow.An instantiation is as follows: at the 1st, 2,3,4,5,6,7 of TXOP, 8 frames, the Group ID used successively is ID1, ID2, ID3, ID4, ID5, ID6, ID6, ID6 respectively.1 STA equipment is represented respectively with the English lower case such as a, b, c ..., l.ID1 indicates 1 group, comprises a, f, k, l.ID2 is by the multiplexing instruction of group 3 groups, and they comprise a, b, c, d respectively, e, f, g, h, i, j, k, l, actual the 1st group a, b, c, d used wherein.ID3 indicates 1 group, comprises e, b, g, l.ID4 is by the multiplexing instruction of group 2 groups, and they comprise a, b, g, h respectively, e, f, k, l.ID5 indicates 1 group, comprises a, g, f, l.ID6 indicates 1 group, comprises b, f, k, l.Further, in this TXOP not the multiplexing fluxion of Existential Space be designated as the situation of 0.Then according to the method for the embodiment of the present invention five, at the 1st, 2,3,4,5,6,7 of this TXOP, 8 frames, TXOP power is saved comprehensive indication bit and can be set gradually as not allowing, and allows, does not allow, and allows, does not allow, and allows, and allows, and allows.

On the other hand, simple in order to what realize, 1 TXOP power that can adopt in regulation embodiment five is saved comprehensive indication bit and get identical value in each frame of a TXOP, thus the value of this bit remains unchanged at each frame of a TXOP; Similar, 1 TXOP power that can adopt in regulation embodiment eight is saved synthesis indication bit and get identical value in each frame of a TXOP, thus the value of this bit remains unchanged at each frame of a TXOP.Introduce corresponding execution mode below.
