Description
Technical field
The present invention relates to have the wireless communication system that high speed downlink packet inserts (HSDPA) technology is the technology that subscriber equipment (UE) distributes high speed descending sharing channel (HS-DSCH), particularly a kind of method for multicarrier UE distribution HS-DSCH.
Background technology
Based on the demand of subscriber equipment to high-speed packet data service, wireless communication system has been introduced the HSDPA technology, this HSDPA technology is by adopting adaptive modulation and coding (AMC) technology and mixing automatic retransmission technique (HARQ) technology, medium access control (MAC) layer in wireless communication system network side and UE increases high speed media access control (MAC-hs) entity, be used for grouped data is transmitted fast the data throughput capabilities of obtaining higher transmission rate and improving sub-district, UE place.
In order to improve the data throughput capabilities of transmission efficiency of packet data and sub-district, UE place, need make full use of the frequency spectrum resource of wireless communication system, promptly improve the availability of frequency spectrum of wireless communication system as much as possible.The wireless communication system of employing HSDPA technology is realized by link circuit self-adapting and fast dispatch the improvement of the availability of frequency spectrum.Each UE of administering at wireless communication system of AMC technology wherein, determine that according to the channel situation that the UE that gets access to sends the suitable code modulation mode that HS-DSCH adopts sends grouped data, the speed of raising transmitting grouped data on the HS-DSCH that distributes for UE realizes fast dispatch; The HARQ technology correctly is received as target by UE with grouped data, automatically determines to retransmit the number of times of same packets data according to the channel situation of the HS-DSCH that distributes for UE, realizes link circuit self-adapting.
Wireless communication system is that HS-DSCH that UE distributes is used for bearing downlink and divides fast data, wireless communication system also is provided with a pair of uplink/downlink control channel for UE simultaneously, be respectively descending being used to and control the high-speed shared information channel (HS-SICH) that the High-Speed Shared Control Channel of HS-DSCH (HS-SCCH) and up being used to report HS-DSCH information, wherein, HS-SCCH carrying UE demodulated packets data parameters needed information is as channel code, time slot position, modulation system or re-transmission verification etc.; HS-SICH is used for affirmation (ACK) or non-affirmation (NACK) information that UE reports the channel situation of current HS-DSCH and whether receives grouped data to the wireless communication system network side.
Based on AMC technology and HARQ technology, when wireless communication system was Frequency Division Duplexing (FDD) (FDD) system, FDD system single carrier can provide the HS-DSCH up to transmission rate 14.4 mbit/(Mbps); When wireless communication system was TD SDMA (TD-SCDMA) system, TD-SCDMA system single carrier can provide the HS-DSCH up to transmission rate 2.8Mbps.
In order further to promote the speed of wireless communication system to the UE transmitting grouped data, multi-transceiver technology and HSDPA technology can be combined, be called the multi-carrier HSDPA technology.The multi-carrier HSDPA technology is exactly to allow to be transferred to the HS-DSCH transmission that the downlink grouped data of a UE can distribute on a plurality of carrier waves of wireless communication system simultaneously, thereby improves the speed of transmitting grouped data greatly.For example, TD-SCDMA system single carrier can provide the HS-DSCH of transmission rate 2.8Mbps, and the n of TD-SCDMA system carrier wave can provide the HS-DSCH of transmission rate n * 2.8Mbps, and n is the natural number greater than 1.
Compare with wireless communication system single carrier HSDPA technology, the difference of wireless communication system multi-carrier HSDPA technology is: the HS-DSCH that the wireless communication system network side will send to UE on the MAC-hs entity of self grouped data is assigned on the multicarrier sends, this UE is called multicarrier UE for supporting from the UE of the HS-DSCH receiving block data of each carrier wave.
The schematic diagram that multicarrier by wireless communication system sends grouped data to multicarrier UE is as shown in Figure 1: the multi-carrier district of wireless communication system is respectively UE HS-DSCH is set on a plurality of carrier waves, and be provided with a pair of or many for UE to HS-SCCH and HS-SICH, the HS-DSCH that distributes on each carrier wave can share in the mode that time-division or sign indicating number divide for a plurality of UE, and a UE can be assigned with the HS-DSCH that is provided with on one or more carrier waves simultaneously.When the grouped data of a UE is transmitted on a plurality of carrier waves simultaneously, MAC-hs entity by the wireless communication system network side is shunted grouped data, be about to packet data streams and be assigned on a plurality of carrier waves, each carrier wave independently adopts the mapping of encoding of the process of HARQ technology afterwards to modulate and send to multicarrier UE.For multicarrier UE, then need to have the ability that receives multi-carrier grouping data, the MAC-hs entity among the multicarrier UE merges when receiving the grouped data that multicarrier sends, and obtains the grouped data that will receive.
As can be seen from Figure 1, in order to realize sending grouped data to multicarrier UE by multicarrier, set up a HARQ entity at the MAC-hs of wireless communication system network side entity for each UE, it is individual that the HARQ entity is that each carrier wave of being administered is set up independent HARQ process (1～8), each HARQ process is independently carried out processing procedure separately, and each process is identified together by carrier identification and process identification (PID).
Each carrier wave in the wireless communication system can respectively have a pair of HS-SCCH/HS-SICH, and this carries out independent control and the feedback of the HS-DSCH of this carrier wave to HS-SCCH/HS-SICH.Each carrier wave can also dispose a pair of or many to HS-SCCH/HS-SICH, selects wherein a pair of independently to control in the business procedure and feeds back HS-DSCH on this carrier wave.
For simplifying the complexity that multicarrier UE realizes, HS-SCCH/HS-SICH has two kinds of configuration modes on carrier wave: the one, all up HS-SICH and all descending HS-SCCH are distributed on the carrier wave, shown in Fig. 2 a; The 2nd, all up HS-SICH and all descending HS-SCCH are carried on respectively on each carrier wave, shown in Fig. 2 b.Can not carry out the multicarrier UE of multicarrier emission for having up link single carrier transmitting capacity, adopt first kind of collocation method.To having the multicarrier UE of up link multicarrier transmitting capacity, two kinds of collocation methods are all feasible.
Based on the consideration to multicarrier UE realizability, the frequency spectrum that wireless communication system is distributed to same multicarrier UE should be no more than the ability level scope that this multicarrier UE reports.To the multicarrier UE of different abilities, can report to wireless communication system and whether support overloading to involve the ability of supporting the multicarrier number, the ability that wireless communication system reports according to multicarrier UE is carried out multi-carrier resource distribution and scheduling.
At present, the process that the wireless communication system that adopts the HSDPA technology is defined as the code modulation mode that HS-DSCH adopts on each carrier wave that UE distributes according to the channel situation that gets access to as shown in Figure 3, in the cordless communication network side of administration multicarrier UE, as setting in advance channel quality indication (CQI) mapping table in the cell base station (NodeB), adopt this CQI mapping table just can obtain the AMC mode that the corresponding HS-DSCH that distributes for multicarrier UE adopts according to CQI value and the transmitting power that multicarrier UE reports, the concrete steps of this method are:
The multicarrier UE of step 300, the linchpin of wireless communication system network side pipe sends self detected CQI value by the HS-SICH with the foundation of wireless communication system network side to the wireless communication system network side.
The downward special physical channel (DPCH) that multicarrier UE and wireless communication system network side are set up can only be based upon on the carrier wave of wireless communication system, and the CQI value that multicarrier UE sends also is to measure descending DPCH to obtain on the carrier wave of having set up descending DPCH.
As can be seen from Figure 3, because the CQI value that multicarrier UE sends is to measure descending DPCH to obtain on the carrier wave of having set up descending DPCH, and when the wireless communication system network side is provided with the code modulation mode of HS-DSCH of other carrier waves for multicarrier UE, all must be with reference to this CQI value, this can cause the code modulation mode of HS-DSCH of other carrier waves of being provided with for multicarrier UE inaccurate.

Prior art wireless communication system network side is owing to the reference value that gets access to for the code modulation mode that HS-DSCH on each carrier wave of multicarrier UE distribution adopts is inaccurate, i.e. the CQI value of multicarrier UE transmission is inaccurate.The CQI value that multicarrier UE sends measures just that a descending DPCH on the carrier wave that is provided with descending DPCH obtains, and can't measure the CQI value for other carrier waves that descending DPCH is not set in the wireless communication system, thereby other carrier waves that descending DPCH is not set can only be sent with reference to multicarrier UE, by measuring the CQI value that a descending DPCH on the carrier wave that is provided with descending DPCH obtains, on this carrier wave, distribute the code modulation mode of HS-DSCH employing for multicarrier UE.Therefore, the present invention is in order to make the wireless communication system network side accurate for the code modulation mode that the HS-DSCH on each carrier wave of multicarrier UE distribution adopts, can on each carrier wave of wireless communication system, descending DPCH be set, measure descending DPCH on each carrier wave of wireless communication system respectively by multicarrier UE, obtain the CQI value of each carrier wave, the CQI value of each carrier wave of obtaining is sent to the wireless communication system network side, and the CQI value of each carrier wave that is sent according to multicarrier UE respectively by the wireless communication system network side is multicarrier UE distributes the HS-DSCH employing on each carrier wave a code modulation mode.
The wireless communication system that Fig. 4 adopts the HSDPA technology for the present invention is defined as the method flow diagram of the code modulation mode that HS-DSCH adopts on each carrier wave that UE distributes according to the channel situation that gets access to, in the cordless communication network side of administration multicarrier UE, as setting in advance the CQI mapping table among the NodeB, adopt this CQI mapping table just can obtain the AMC mode that the corresponding HS-DSCH that distributes for multicarrier UE adopts according to CQI value and the transmitting power that multicarrier UE reports, the concrete steps of this method are:
The multicarrier UE of step 401, the linchpin of wireless communication system network side pipe measures the descending DPCH of each carrier wave in the wireless communication system respectively, after obtaining the CQI value of each carrier wave, the HS-SICH of each carrier wave by wireless communication system sends the CQI value of each carrier wave to the wireless communication system network side respectively.
The maximum transmission power that step 402, wireless communication system network lateral root can distribute for multicarrier UE according to CQI value and current each carrier wave of each carrier wave that receives respectively, in the CQI mapping table, find the AMC mode that each carrier wave adopts respectively, thereby determine the code modulation mode that SH-DSCH adopted of each carrier wave respectively, adopt the code modulation mode of determining respectively to multicarrier UE transmitting grouped data by the HS-DSCH on each carrier wave.
In step 401 shown in Figure 4, measure the CQI value of each carrier wave respectively as multicarrier UE after, can be not yet respectively the HS-SICH of each carrier wave by wireless communication system send the CQI value of each carrier wave to the wireless communication system network side, but the CQI value of each carrier wave that will obtain sends the CQI value of each carrier wave to the cordless communication network side by the HS-SICH of one of them carrier wave in each carrier wave of wireless communication system corresponding to the sign of each carrier wave.
In the present invention, the wireless communication system network side can not be provided with descending DPCH for all carrier waves yet, and just by the carrier wave that HS-DSCH sends grouped data descending DPCH is set for the current multicarrier UE that will give, thereby be provided with the descending DPCH of the carrier wave of descending DPCH by multicarrier UE measurement, obtain the current CQI value that send the carrier wave of grouped data will for by HS-DSCH multicarrier UE.At this moment, whether multicarrier UE can report to wireless communication system and support overloading to involve the ability of supporting carrier number, the wireless communication system network lateral root distributes more than one carrier wave according to the ability that multicarrier UE reports for multicarrier UE, and the HS-DSCH that passes through each carrier wave of being distributed sends grouped data to UE.For example, in fact the wireless communication system network side has 5 carrier waves, but 3 carrier waves have been distributed for multicarrier UE according to the ability that multicarrier UE reports, then the wireless communication system network side is provided with descending DPCH only for 3 carrier waves that distribute for this multicarrier UE, thereby this multicarrier UE only measures the descending DPCH that these 3 carrier waves are provided with, and obtains the CQI value of these 3 carrier waves.
In the present invention, wireless communication system also can be provided with descending DPCH for all carrier waves, but multicarrier is when measuring the descending DPCH of carrier wave, all do not measure the descending DPCH of all carrier waves, and be the descending DPCH of measure portion carrier wave, this part carrier wave is the current carrier wave that send grouped data will for by HS-DSCH multicarrier UE.At this moment, multicarrier UE can select the descending DPCH of more than one carrier wave to measure according to the ability of self supporting carrier number equally, obtains the CQI value.For example, in fact the wireless communication system network side has 5 carrier waves, for multicarrier UE has distributed 5 carrier waves and descending DPCH has been set for respectively these 5 carrier waves, but this multicarrier UE obtains the CQI value of 3 carrier waves in these 5 carrier waves according to self supporting the ability of carrier number only to measure the descending DPCH of 3 carrier waves in these 5 carrier waves.
In the present invention, described multicarrier UE has up link single carrier transmitting capacity and can not carry out the multicarrier UE of multicarrier emission or for having the multicarrier UE of up link multicarrier transmitting capacity.
