The method comprises the following steps of configuring a dedicated SIB (System Information Block) message, a paging message and an RAR (Random Access Response) message which are scheduled, has fixed format and used for the MTC UE in a PDSCH (Physical Downlink Shared Channel); broadcasting normal PDCCH (Physical Downlink Control Channel) and the PDSCH.
Description
Technical field
The present invention generally relates to wireless communication field, more specifically, relates to a kind of method and apparatus of the wireless coverage for strengthening MTC UE.
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 in the fields such as intelligent transportation, long-range charge, remote monitoring at present.The machine (equipment) participating in M2M communication is also referred to as MTC subscriber equipment (MTC UE).
At third generation partner program (3GPP) Long Term Evolution (Long Term Evolution, LTE) in system, according to the difference of action scope, physical downlink control channel (Physical Downlink Control Channel, PDCCH) carry Downlink Control Information (the Downlink Control Information for one or more UE, DCI), beared information is divided into common control information (public search space (Common Search Space, CSS)) and dedicated control information (dedicated search space).Wherein CSS is mainly used in sending some instructions to UE, as system information RNTI (System Information RNTI, SI-RNTI), paging RNTI (Paging RNTI, and Stochastic accessing RNTI (Random Access RNTI P-RNTI), RA-RNTI), with to the information of notification of user equipment desired by them, as system information block (System Information Block, SIB) message, paging (Paging) message and accidental access response (Random Access Response, RAR) message, whether transmit in distributed resource.
Physical Downlink Shared Channel (Physical Downlink Shared Channel, the PDSCH) time division multiplexing of PDCCH and transmitting downlink data.UE carries out blind check in PDCCH control area, and whether search exists the PDCCH sent for it.Namely blind check uses the corresponding Radio Network Temporary Identifier of this UE (Radio Network Temporary Identity, RNTI) to carry out decoding to PDCCH and attempts.If decoding is correct, then receive the DCI for this UE, in PDSCH, then receive corresponding message.
Current, 3GPP begins one's study and the coverage enhancement 15dB of MTC UE is obtained obvious commercial interest to make MTCUE supplier, and the low cost MTC UE in GSM/GPRS can be moved in LTE network by operator.For MTC UE, the consideration for low cost is only equipped with an antenna usually, does not therefore strengthen covering by space diversity.Extend the transmission time, namely repeatedly retransmit, be considered as a kind of major technique obtaining this huge income.Simulation result shows, by being repeated to send the target that can realize the above-mentioned coverage enhancement of MTC UE for 80-100 time by PDCCH (or the PDCCH (i.e. EPDCCH) strengthened).But, in order to realize MTC UE coverage enhancement and repeatedly repeat transmission PDCCH/EPDCCH (delay etc. such as increasing common UE) will be had a negative impact to the PDCCH reception of common UE (non-MTC UE), especially for public search space (CSS), because CSS is shared by all UE in community, and its resource is very limited.If repeated 80-100 time by CSS in order to the covering strengthening MTC UE, then base station can not send enough information for common UE in these 80-100 subframe, as RNTI etc.Therefore need the new scheme of research to minimize the adverse effect to common UE to the coverage enhancement realizing low cost MTC UE simultaneously.
On the other hand, EPDCCH does not support that CSS transmits.In addition, EPDCCH-PRB-set is specific to user.Before UE starts monitoring, network notifies the EPDCCH-PRB-set of its correspondence to MTCUE by high-level signaling.Therefore, this method is not suitable for initial access, because can not receive RA-RNTI when sending Msg2 before sending high-level signaling.In addition, it may increase the size of EPDCCH and thus need a large amount of Standard modification.
In addition, MediaTek Inc (MediaTek Inc.) suggested a kind of scheme of the coverage enhancement for low cost MTC UE, wherein eliminate PDCCH/EPDCCH transmission, MTC UE carries out blind check with common UE to the same way of PDCCH blind check to all possible candidate target in PDSCH.This scheme has obviously shortcoming, and it greatly increases the complexity of UE and the power consumption on each possible opportunity to all candidate target trial blind checks, will increase the operating time of low cost MTC UE greatly.This problem is particularly remarkable when seldom using.In addition, this scheme also needs to carry out many amendments and definition to standard.
Therefore, current scheme all can not well work, and needs to define new scheme.
Summary of the invention
For above problem, invention proposes a kind of when not affecting the reception of non-MTC UE, making MTC UE can walk around the CSS in PDCCH and in PDSCH, directly obtain the scheme of information needed.

Embodiment
Below with reference to accompanying drawings preferred implementation of the present disclosure is described in more detail.Although show preferred implementation of the present disclosure in accompanying drawing, but should be appreciated that, the disclosure can be realized in a variety of manners and not should limit by the execution mode of setting forth here.On the contrary, provide these execution modes to be to make the disclosure more thorough and complete, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
As mentioned above, some instructions of some information are comprised in the CSS of PDCCH, for notify to UE message (as SIB message, beep-page message and RAR message) desired by them whether send in the resource of distributing, such as notify the transmission in which or which Physical Resource Block (PRB) of PDSCH of these message to UE.In current standard, the form of these message, take resource and some power contorl parameters flexible dispatching in CSS.In this way, these message can be configured in PDSCH according to suitable Modulation and Coding Scheme (Modulation and Coding Scheme, MCS) according to its size.This makes to dispatch these message for UE and becomes very complicated.
But because low cost MTC UE covers limited, therefore to carry out the benefit of flexible dispatching very limited for its PDSCH sent of subtend.First, because the signal that receives and interference-to-noise ratio (SINR) are expected very low, the MCS (namely having the QPSK of most high code-rate) with low data rate is almost always preferred.In addition, consider the low-down spectrum efficiency of the MTC UE of coverage enhancement, the capacity of PDSCH is very little, and therefore each message should simplify.As a result, the size of each message may fix or select considerably less.In this case, flexible dispatching SIB, paging and RAR message can be come by static or semi-persistent scheduling.In addition, the low cost MTC UE in covering cavity is preferably with maximum power transmission.
Therefore, if pre-determine the possible situation of CSS indication information, and the parameter of correspondence is by system information block type 1 (SIB1) information broadcast, namely, which PRB of which subframe comprises beep-page message, SIB message and the RAR message that MTC UE knows, then MTCUE no longer may need CSS, thus can walk around CSS.Invention proposes the semi-persistent scheduling scheme of a kind of SIB message, beep-page message and RAR message, strengthening the covering of low cost MTC UE by walking around CSS.
Be explained respectively for three kinds of main message indicated by CSS below.
SIB message
Each UE must receive some system informations before starting to receive CSS.For common UE, this information sends in SIB1 message.SIB1 comprises the schedule information of carrier information and other system information (as SIB2......SIB12).For MTC UE, the present invention advises designing new special SIB message for MTC UE, send some information desired by it by broadcasting this special SIB message in the SIB1 of PDSCH to MTC UE, other information can send in the SIB2 for common UE.
Can be that SIB1 message in communicating with common UE is identical by the priority design of this new SIB1 message for MTC UE.If also need other SIB message, then this special SIB message can also indicate the schedule information of other SIB message, as opportunity and the number of repetition of other SIB message for MTC UE.The transmission opportunity of other SIB message should be configured completely by this new special SIB.
In other words, for MTC UE, the SI-RNTI in CSS need not be used to receive other SIB, but other SIB can be received by designed new special SIB.This is possible, because first, SI-RNTI is mainly used in the large SIB information of the discontinuous reception of common UE, and MTC UE does not need to receive so large SIB usually.In addition, the repeating of CSS causes the wasting of resources, counteracts the benefit using SI-RNTI.
Therefore, in the present invention, advise for MTC UE, in pre-configured resource, send SIB message with set form.
Beep-page message
For the minimum 1.4MHz bandwidth with 6 PRB, each subframe can send at most 192 bits according to the MCS with lowest data rate.In order to alleviate the impact for common UE, available resources may be less than 192 bits.Consider at least 8 bits that MAC head takies, other payload in 24 bits that CRC takies and beep-page message, space in each beep-page message only may reach paging 1 or 2 UE, because each UE identification code comprises international mobile subscriber identity (the International Mobile Subscriber Identity of 32 bits, the temporary mobile subscriber identity (S-Temporary Mobile Subscriber Identity, S-TMSI) of IMSI) or 40 bits.
The beep-page message of known multiplexing multiple UE can reduce the cost that media interviews control (MAC) head, cyclic check (CRC) and other payload.But for low cost MTC UE, the length of maximum paging list is very little, maximum 2.If use variable paging list for MTC UE, then need to indicate P-RNTI with DCI format 1A in CSS.Needs are taken 20 or more original bit (PDCCH for DCI format 1A) for paging by this in the CSS of PDCCH.Therefore, the benefit provided by the ID loading multiple MTC UE in a beep-page message is very limited, but cost is but very serious to the reduction of the CSS capacity of common UE.
Therefore, in the present invention, advise for MTC UE, in pre-configured resource, send beep-page message with set form.Preferably, each beep-page message is only applied to a MTC UE (that is, paging list size is 1).Further, the form of beep-page message is fixed, that is, beep-page message is with fixed-length code (FLC).
As a selectable option, not there is mobility due to a lot of MTC UE or mobility is lower, so can always use IMSI to be used as the identification code (UE ID) of MTC UE.
In addition, can resource in the above-mentioned new special SIB designed for MTC UE shared by broadcast paging messages, that is, take which PRB a paging occasion.
RAR message
Similar with beep-page message, RAR message also supports the multiplexing of multiple MAC RAR payload.Define each MAC RAR payload and take 48 bits.Consider that CRC takies 24 bits and MAC head takies at least 13 bits, can the conclusion similar with beep-page message be drawn: in a MAC RAR PDU (Protocol Data Unit, protocol Data Unit), 1 to 2 MAC RAR payload can only be had.And send at most 2 MACRAR payload and make multiplexing benefit almost negligible, but cost is but the reception adversely affecting common UE.
Therefore, in the present invention, advise for MTC UE, in pre-configured resource, send RAR message with set form.Preferably, each MAC RAR PDU only comprises the MAC RAR payload for a MTC UE.Further, the form of MAC RAR payload is fixed.
In addition, the resource of RAR message can be broadcasted in the above-mentioned new special SIB for MTC UE design, that is, RAR window (start SFN (System Frame Number, System Frame Number) and subframe numbers, number of repetition etc.) and take which PRB accurately.
Based on above discussion, by the description below in conjunction with accompanying drawing, specific implementation of the present invention is described.
