Description
Technical field
The present invention is generally related to wireless communication field, more specifically, is related to a kind of nothing for enhancing MTC UE
The method and apparatus of line covering.
Background technology
Machine to machine (Machine to Machine, M2M) communication is also referred to as machine type communication (Machine Type
Communications, MTC), be the pattern communicated between a kind of machine and machine, be widely used at present intelligent transportation,
The fields such as long-range charge, remote monitoring.The machine (equipment) for participating in M2M communication is also referred to as MTC user equipmenies (MTC UE).
In third generation partner program (3GPP) long term evolution (Long Term Evolution, LTE) system, root
According to the difference of action scope, physical downlink control channel (Physical Downlink Control Channel, PDCCH)
Carry the Downlink Control Information (Downlink Control Information, DCI) for one or more UE, carrying letter
Breath is divided into common control information (public search space (Common Search Space, CSS)) and dedicated control information is (special
Search space).Wherein CSS is mainly used for sending some instructions to UE, such as system information RNTI (System Information
RNTI, SI-RNTI), paging RNTI (Paging RNTI, P-RNTI) and random access RNTI (Random Access RNTI,
RA-RNTI), with their desirable information to notification of user equipment, such as system information block (System Information
Block, SIB) message, paging (Paging) message and random access response (Random Access Response, RAR) disappear
Breath, if transmitted in the resource distributed.
Physical Downlink Shared Channel (the Physical Downlink Shared of PDCCH and transmission downlink data
Channel, PDSCH) time division multiplexing.UE carries out blind examination in the control areas PDCCH, and search is with the presence or absence of for its transmission
PDCCH.Blind examination is corresponding radio network temporary identifier (the Radio Network Temporary using the UE
Identity, RNTI) trial is decoded to PDCCH.If decoding is correct, the DCI for the UE is received, is then existed
Corresponding message is received in PDSCH.
Currently, 3GPP begins one's study the coverage enhancement 15dB of MTC UE so that MTCUE suppliers obtain apparent quotient
Industry interests, and enable an operator to move to the inexpensive MTC UE in GSM/GPRS in LTE network.MTC UE are come
It says, the consideration for low cost is usually equipped only with an antenna, therefore cannot enhance covering by space diversity.Extend and passes
The defeated time repeatedly retransmits, is considered as obtaining a kind of major technique of this huge income.Simulation result is shown, is passed through
PDCCH (or PDCCH (i.e. EPDCCH) of enhancing) is repeated to send the 80-100 above-mentioned covering increasing that MTC UE may be implemented
Strong target.However, in order to realize the coverage enhancement of MTC UE and transmission PDCCH/EPDCCH is repeated several times will be (non-to common UE
MTC UE) PDCCH reception have an adverse effect (such as increasing the delay etc. of common UE), especially for public search space
(CSS) for, because CSS is shared by all UE in cell, and its resource is very limited.If in order to enhance MTC UE's
It covering and repeats CSS 80-100 times, then base station cannot be that common UE sends enough information in these 80-100 subframe,
Such as RNTI.Therefore it needs to study new scheme to realize the coverage enhancement of inexpensive MTC UE while minimize to common UE's
Adverse effect.
On the other hand, EPDCCH does not support CSS to transmit.In addition, EPDCCH-PRB-set is specific for user's.It is opened in UE
Begin before monitoring, network notifies its corresponding EPDCCH-PRB-set by high-level signaling to MTCUE.Therefore, this method
It is not suitable for being initially accessed, because RA-RNTI when sending Msg2 cannot be received before sending high-level signaling.In addition, it
The size of EPDCCH may be increased and to need a large amount of modification standards.
In addition, MediaTek Inc (MediaTek Inc.) is it has been proposed that a kind of being used for low cost MTC
The scheme of the coverage enhancement of UE, wherein eliminating PDCCH/EPDCCH transmission, MTC UE are to all possible candidate in PDSCH
Object carries out blind examination with common UE to the same way of PDCCH blind examinations.This scheme has the shortcomings that clearly, greatly
It increases the complexity of UE and on each possible opportunity all candidate targets is attempted with the power consumption of blind examination, will greatly increase low
The working time of cost MTC UE.This problem is especially pronounced in the case of rarely needed.In addition, this scheme also needs to pair
Standard carries out many modifications and definition.
Therefore, current scheme cannot all work well, need to define new scheme.

Specific implementation mode
The preferred embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Preferred embodiment, however, it is to be appreciated that may be realized in various forms the disclosure without the embodiment party that should be illustrated here
Formula is limited.On the contrary, these embodiments are provided so that the disclosure is more thorough and complete, and can be by the disclosure
Range is completely communicated to those skilled in the art.
As described above, some instructions comprising some information in the CSS of PDCCH, for being notified desired by them to UE
Message (such as SIB message, paging message and RAR message) whether sent in the resource distributed, such as notify these to UE
Message transmission in which or which Physical Resource Block (PRB) of PDSCH.In current standard, the format of these message accounts for
With resource and some power contorl parameters flexible dispatching in CSS.In this way, these message can be pressed according to its size
According to Modulation and Coding Scheme appropriate (Modulation and Coding Scheme, MCS) configuration in PDSCH.This makes pair
These message are dispatched for UE becomes extremely complex.
However, since inexpensive MTC UE coverings are limited, the benefit of flexible dispatching is carried out to the PDSCH being sent to
It is very limited.Firstly, since the signal received and interference-to-noise ratio (SINR) expection are very low, the MCS with low data rate
(i.e. the QPSK with highest encoding rate) is almost always preferred.In addition, it is contemplated that the MTC UE's of coverage enhancement is low-down
The capacity of spectrum efficiency, PDSCH is very small, therefore each message should simplify.As a result, the size of each message may fix
Or selection is considerably less.In such a case, it is possible to be disappeared come flexible dispatching SIB, paging and RAR by static or semi-persistent scheduling
Breath.In addition, the inexpensive MTC UE in covering cavity are preferably with maximum power transmission.
Therefore, if predefining the possibility situation of CSS instruction information, and corresponding parameter passes through system information block class
Type 1 (SIB1) message is broadcasted, that is, which PRB of which subframe disappears comprising paging message, SIB message and RAR that MTC UE know
Breath, then MTCUE may no longer need CSS, so as to bypass CSS.Invention proposes a kind of SIB message, paging message and
The semi-persistent scheduling scheme of RAR message, by the covering for enhancing inexpensive MTC UE around CSS.
It is explained respectively below for three kinds of main message by CSS instructions.
SIB message
Each UE must receive some system informations before starting to receive CSS.For common UE, which exists
It is sent in SIB1 message.SIB1 includes the scheduling information of carrier information and other systems information (such as SIB2......SIB12).It is right
For MTC UE, it is proposed that for the new special SIB message of MTC UE designs, it should by being broadcasted in the SIB1 of PDSCH
Special SIB message sends its some desirable information to MTC UE, other information can be in the SIB2 for common UE
Middle transmission.
Can will be and the SIB1 message in common UE communication for the priority design of the new SIB1 message of MTC UE
It is identical.If also needing to other SIB message, which also can indicate that the scheduling information of other SIB message, such as
The opportunity of other SIB message for MTC UE and number of repetition.The transmission opportunity of other SIB message should be new special by this
SIB is configured completely.
In other words, for MTC UE, it is not necessary to receive other SIB using the SI-RNTI in CSS, but can be with
Other SIB are received by designed new special SIB.This is possible, because first, SI-RNTI is mainly used for commonly
UE discontinuously receives big SIB information, and MTC UE are not usually required to receive so big SIB.In addition, the repetition of CSS causes
The wasting of resources counteracts the benefit using SI-RNTI.
Therefore, in the present invention, it is proposed that for MTC UE, sent with set form in preconfigured resource
SIB message.
Paging message
For the minimum 1.4MHz bandwidth with 6 PRB, each subframe can be according to the MCS with lowest data rate most
It is multiple to send 192 bits.In order to mitigate the influence for common UE, available resources are possibly less than 192 bits.In view of MAC header accounts for
At least 8 bits, other payload in 24 bits and paging message that CRC is occupied, the space in each paging message
1 or 2 UE only may be enough paged, because each UE identification codes include the international mobile subscriber identity of 32 bits
The temporary mobile subscriber identity of (International Mobile Subscriber Identity, IMSI) or 40 bits
(S-Temporary Mobile Subscriber Identity, S-TMSI).
The paging message of the multiple UE of known multiplexing can reduce media access control (MAC) head, cyclic check (CRC) and its
The cost of his payload.However, for inexpensive MTC UE, the length of maximum paging list is very small, most 2.
If for MTC UE using variable paging list, need to indicate P-RNTI with DCI format 1A in CSS.This will be needed
20 or more original bits (for PDCCH of DCI format 1A) are occupied in the CSS of PDCCH for paging.Therefore,
The ID that multiple MTC UE are loaded in a paging message is provided the advantage that very limited, but cost is to common UE
The reduction of CSS capacity is very serious.
Therefore, in the present invention, it is proposed that for MTC UE, sent with fixed format in preconfigured resource
Paging message.Preferably, each paging message is only applied to a MTC UE (that is, paging list size is 1).Also, it pages
The format of message is fixed, that is, paging message is with fixed-length code (FLC).
As an optional option, since many MTC UE are relatively low without mobility or mobility, it is possible to always
It is used as the identification code (UE ID) of MTC UE using IMSI.
Furthermore, it is possible to the occupied resource of broadcast paging messages in the above-mentioned new special SIB designed for MTC UE,
That is, which PRB occupied in a paging occasion.
RAR message
Similar with paging message, RAR message also supports the multiplexing of multiple MAC RAR payload.It has been defined for each
MAC RAR payload occupies 48 bits.Occupy at least 13 bits in view of CRC occupies 24 bits and MAC header, can be derived that with
The similar conclusion of paging message：Can only have 1 in one MAC RAR PDU (Protocol Data Unit, protocol Data Unit)
To 2 MAC RAR payload.And it at most sends 2 MACRAR payload and the benefit of multiplexing can almost be ignored not
Meter, but cost is adversely to influence the reception of common UE.
Therefore, in the present invention, it is proposed that for MTC UE, sent with fixed format in preconfigured resource
RAR message.Preferably, each MAC RAR PDU only include the MAC RAR payload for a MTC UE.Also, MAC
The format of RAR payload is fixed.
Furthermore, it is possible to broadcast the resource of RAR message in the above-mentioned new special SIB designed for MTC UE, that is, accurate
RAR windows (starting SFN (System Frame Number, System Frame Number) and subframe numbers, number of repetition etc.) and occupancy which
PRB。
