Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Referring to Fig. 1, be the PDCCH transmission flow schematic diagram that the embodiment of the present invention provides, this flow process can comprise:
Step 101, the PDCCH of corresponding transmission mode, according to the type information for the treatment of dispatch terminal, is determined in base station, functional characteristics and characteristic demand that the DCI form of the PDCCH of described corresponding transmission mode is supported with the terminal type of described terminal are corresponding;
Step 102, the PDCCH that base station sends described corresponding transmission mode to this terminal is to carry out up-downgoing data dispatch.
In end side, corresponding terminal receives and resolves this PDCCH to carry out up-downgoing transfer of data according to the scheduling of base station, and functional characteristics and characteristic demand that the DCI form of this PDCCH is supported with the terminal type of this terminal are corresponding.
The terminal here comprises MTC terminal or M2M terminal, and the type terminal has the features such as the low time delay of communication, small data quantity.The functional characteristics that the type terminal is supported and characteristic demand, can comprise one of following or combination in any:
(1) terminal hardware or software are not supported TTI bundling(Transmission Time Interval) function and SPS(semi-continuous scheduling) function;
(2) terminal hardware or software are not supported many antennas, only support single antenna;
(3) terminal hardware or software are not supported the many antenna port transmission of ascending multi-code word;
(4) terminal hardware or software are not supported MIMO(multiple-input and multiple-output); Concrete, do not support MIMO to refer to one of following situation or combination in any: to support limited quantity port transmission, do not support multilayer transmission, do not support two codeword transmission;
(5) terminal hardware or software are not supported high order modulation;
(6) terminal hardware or software are not supported carrier aggregation;
(7) terminal hardware or software are not supported large bandwidth, only support little bandwidth;
(8) the HARQ(Hybrid Automatic Repeat Request of terminal hardware or software support, mixed automatic retransfer request) minimizing of process number.
So-called terminal hardware is not supported certain function, and the corresponding hardware typically referring in terminal does not have this function, and for example, terminal antenna is single antenna, therefore cannot support many antenna functions.So-called terminal software is not supported to typically refer to the in the situation that of certain function of hardware supports, because not loading the software module of supporting corresponding function, even or loaded the software module of support corresponding function but do not activated or open the function that this software module realizes, cause this terminal cannot support the situation of this function.
To in above-mentioned process step 101, base station, according to the type information of terminal, determines that the process of the PDCCH of corresponding transmission mode is described in detail below.
Transmission mode is the set of a series of transmission characteristics, can comprise DCI form, PDCCH search volume, PDCCH scrambling RNTI(Radio Network Temporary Identifier, Radio Network Temporary Identifier) etc., below respectively from these aspects explanation embodiment of the present invention according to the transmission mode of MTC terminal or the designed PDCCH of M2M terminal.
(1) aspect DCI length
The designed PDCCH of the embodiment of the present invention has identical DCI length, and this length can be length maximum in all DCI length, and the DCI of this maximum length of curtailment, is filled to this maximum length.This identical DCI length can be also a certain than the larger length of maximum length in all DCI length, and the remaining bits in the DCI of this length can be reserved expansion.
(2) aspect PDCCH scrambling RNTI
If the DCI length that the embodiment of the present invention is supported with H2H terminal for the DCI length of MTC Terminal Design is identical, need to come scrambling to distinguish with the RNTI that is different from H2H terminal.For example, H2H terminal is used C-RNTI(Cell RNTI, community RNTI) scrambling PDCCH, MTC terminal is used MTC-C-RNTI scrambling PDCCH.Distinguished in this way, can guarantee that the blind check of H2H terminal is unaffected, and then avoid making a mistake, guaranteed that the normal data of H2H terminal receives.
(3) aspect PDCCH search volume
The designed PDCCH of the embodiment of the present invention can only dispatch for the exclusive search volume of terminal, the PDCCH of public space is used the DCI form identical with original H2H terminal, for example also use existing 1A and 1C, length, format and content are all constant, can not affect like this reception of H2H terminal public information and random access information.
The designed PDCCH of the embodiment of the present invention also can, both for the exclusive space scheduling of terminal, also dispatch for public space.So likely can cause the resource of the PDCCH of original H2H terminal to be seized by MTC terminal, but for MTC terminal, the PDCCH blind check number of times of public space reduce by half.
(3) aspect DCI form
Various functional characteristics and characteristic demand that the embodiment of the present invention above MTC terminal of basis or M2M terminal are supported, designed DCI form comprises following situation:
(a), in the situation that terminal is not supported TTI bundling function and SPS function, do not support the DCI form under SPS C-RNTI configuration.
(b) in terminal, do not support many antennas, only support in the situation of single antenna, DCI form quantity reduces (on the basis of existing DCI form, reducing DCI form).
For example, terminal for Release 10, support at present TM1 to TM9 totally 9 kinds of transmission modes, when terminal limitations is for only supporting single antenna, the downlink transfer pattern of terminal support can comprise one of following or combination: TM1(TM:Transmission mode, transmission mode), TM2, TM6, TM7, TM8, TM9, so corresponding DCI form is reduced to maximum 5 kinds from 8 kinds of forms, i.e. DCI1A, DCI 1, DCI 1B, DCI 2B or DCI 2C.
(c) in the situation that terminal is not supported the many antenna port transmission of ascending multi-code word, DCI form quantity reduces (on the basis of existing DCI form, reducing DCI form).
For example, for the terminal of Release 10, support at present 4 two kinds of DCI forms of DCI0 and DCI, if terminal is not supported uplink multi-antenna port transmission, do not support DCI 4, only support DCI0.
(d) in the situation that terminal is not supported MIMO, in DCI form, reduce two codeword transmission, number of plies indication, port indication, precoding information bit number, the information field of second codeword transmission piece, precoding, and the descending power of multiuser MIMO (MU-MIMO) skew bit, for example:
I. reduce by second information field that codeword transmission piece is corresponding, specifically can comprise: reduce MCS indication (5 bit), reduce new data indication (1 bit), reduce RV version (2 bit) and indicate corresponding bit number, reduce altogether by 8 bits;
Ii. reduce precoding information, specifically can comprise: reduce 6 bits (4 port) information for DCI2 and DCI4, for example reducing to is respectively 4 bits and 5 bits, or reduce for 0 bit (2 port) of DCI2A or 2 bits (4 port) to 0 bit;
Iii. transmission block also can reduce to 1 bit of code word exchange identification; Mainly for DCI2 and DCI 2A.
Iv. the information bit of the number of plies and port indication can reduce.For example, for DCI 2C, can be by antenna port, 3 bit indications of scrambler indication and layer number are reduced to 2 bit indications.
V. reduce descending power skew bit 1 bit of multiuser MIMO (MU-MIMO), for example, for DCI 1D.
(e) in the situation that terminal is not supported high order modulation, 5 bit MCS(scheduling coded systems in corresponding DCI form) indication (can the highest support 64QAM, wherein QAM is the english abbreviation of Quadrature Amplitude Modulation, represents quadrature amplitude modulation) can be reduced to 4 bits (the highest support 16QAM).If do not support 64QAM and 16QAM, or need the transport block size index of indication to tail off, so, MCS indication bit number can further reduce.This operation can be for all DCI forms.
(f) in the situation that terminal is not supported carrier aggregation, the carrier wave indication territory (0-3 bit) in corresponding DCI form can be reduced, and this operation can be for all DCI forms.
(g) in terminal, do not support large bandwidth, only support in the situation of little bandwidth, in corresponding DCI form, information bit can correspondingly reduce, but terminal need to can be supported the corresponding DCI length of maximum bandwidth in supported bandwidth, and this operation can be for all DCI forms.
(h) in the situation that the HARQ process number that terminal is supported reduces, for example, only support 1 process, in DCI form, irrelevant information bit is indicated.If terminal is only supported 2 processes, in DCI form, from original bit number (being 4 bits for TDD system, is 3 bits for FDD system), be reduced to 1 bit indication.If terminal can be supported more multi-process, for example maximum 4 processes, are reduced to 2 bit indications from original bit number (being 4 bits for TDD system, is 3 bits for FDD system) in DCI form.This operation can be for the DCI form of all descending schedulings.
Further, owing to comprising two kinds of DCI forms in every kind of transmission mode, DCI 1A and DCI X, therefore need to increase by 1 bit identification (DCI flag) distinguishes two kinds of forms, for example 0 identify DCI 1A, 1 sign DCI X, wherein, DCI X identifies above-mentioned DCI 1, DCI 1B, DCI 2B, DCI 2C.
More specifically, suppose that MTC terminal These characteristics and characteristic demand all support, according to analysis above, can only redesign DCI 0, DCI1, DCI1A, DCI 1B, DCI 2B, DCI 2C so.According to principle above, carry out information bit minimizing, the useful information specifically comprising is if table 24 is to as shown in table 31.All DCI form keeps length consistent, and to take maximum DCI length be reference, and useful information is inadequate, can filling bit to maximum length, untapped bit can be used as reserved bit, as other later expansions.
The length of DCI is relevant to the process number that bandwidth and HARQ support, supposes to support that bandwidth is that 1.4M or maximum support bandwidth are 5M, and HARQ can support maximum 4 processes, and the length of the DCI form that the embodiment of the present invention is designed is:
In the situation that maximum is supported 1.4M bandwidth: DCI 0 is 24 bits, and DCI 1 is 21 bits, and DCI 1A is 21 bits, and DCI 1B is 23 bits, and DCI 2B is 22 bits, and DCI 2C is 23 bits.Therefore can using the unified length of 24 bits as all DCI.For some DCI, remaining bits can be used as reserved bit, as expansion afterwards, uses.Or, can using a certain length that is greater than 24 bits as with reference to length, 26 bits for example, remaining bits is reserved.
In the situation that maximum is supported 5M bandwidth: DCI 0 is 28 bits, and DCI 1 is 28 bits, and DCI 1A is 25 bits, and DCI 1B is 25 bits, and DCI 2B is 29 bits, and DCI 2C is 30 bits.Therefore can using the unified length of 30 bits as all DCI.For some DCI, remaining bits can be used as reserved bit, as expansion afterwards, uses.Or, can using a certain length that is greater than 30 bits as with reference to length, 32 bits for example, remaining bits is reserved.
It should be noted that, if the DCI length that the designed DCI length of the embodiment of the present invention is supported with H2H terminal is identical, need to come scrambling to distinguish with different terminal iidentification RNTI, for example H2H terminal is used C-RNTI, and MTC terminal is used MTC-C-RNTI; If do not distinguished, can affect the blind check of H2H terminal, the generation that leads to errors, affects the normal reception of H2H terminal.

Below by comparative analysis, the impact of the embodiment of the present invention on PDCCH blind check is described.Specifically describe in two kinds of situation:
Situation 1: the designed PDCCH of the embodiment of the present invention is not only applied to the exclusive space scheduling of UE, is also applied to public space scheduling.Now, all DCI form length that UE supports are identical, comprise the DCI 1C etc. that carries common control information.
The in the situation that of system bandwidth 1.4M, suppose that the maximum bandwidth that UE supports is 1.4M, so now physical resource is few, and polymerization grade CCE=8 also can not support.Can redefine the candidate PDCCH number of CCE polymerization grade and candidate PDCCH number mapping table in existing LTE system, remove CCE=8.Now UE public search space only needs the length of a kind of DCI form of blind check, and resource number is 4, and blind check is PDCCH4 time altogether; For the exclusive search volume of UE, the polymerization grade of CCE can be 1,2,4, and under corresponding CCE polymerization grade, PDCCH resource number is that { 6,6,2}, only needs the length of a kind of DCI form of blind check, and blind check is 6+6+2=14 time so altogether.Therefore, UE blind check number of times is altogether 4+14=18 time, and while adopting prior art frequently required 44 times, blind check number of times reduces greatly.
In the situation that system bandwidth is greater than 1.4M, suppose that the maximum bandwidth that UE supports is greater than 1.4M, for example 5M.UE public search space now, CCE polymerization grade is 4,8, under corresponding polymerization grade, PDCCH resource number is that { 4,2}, only needs the length of a kind of DCI form of blind check, and blind check PDCCH is 4+2=6 time altogether.For the exclusive search volume of UE, the polymerization grade of CCE can be 1,2,4, and under corresponding CCE polymerization grade, PDCCH resource number is that { 6,6,2}, only needs the length of a kind of DCI form of blind check, and blind check is 6+6+2=14 time so altogether.Therefore, UE blind check number of times is altogether 6+14=20 time.Compare 44 times required while adopting prior art, blind check number of times reduces greatly.
Situation 2: the PDCCH of embodiment of the present invention design is only applied to the exclusive space scheduling of UE, shall not be applied to public space scheduling.Now, identical with existing LTE system for the DCI form of carrying common control information, for the form of the new unified length of all DCI uses of the PDCCH under carrying C-RNTI configuration.
In the situation that system bandwidth is 1.4M, suppose that the maximum bandwidth that UE supports is 1.4M, so now physical resource is few, and polymerization grade CCE=8 also can not support.Can redefine the candidate PDCCH number in table 4, remove CCE=8.Now UE public search space needs the length of 2 kinds of DCI forms of blind check, and resource number is 4, and blind check is PDCCH2*4=8 time altogether; For the exclusive search volume of UE, the polymerization grade of CCE can be 1,2,4, and under corresponding CCE polymerization grade, PDCCH resource number is that { 6,6,2}, only needs the length of a kind of DCI form of blind check, and blind check is 6+6+2=14 time so altogether.Therefore, UE blind check number of times is altogether 8+14=22 time, and while adopting prior art frequently required 44 times, blind check number of times reduces greatly.
In the situation that system bandwidth is greater than 1.4M, suppose that the maximum bandwidth that UE supports is greater than 1.4M, for example 5M.UE public search space now, CCE polymerization grade is 4,8, under corresponding polymerization grade PDCCH resource number be 4,2} needs the length of 2 kinds of DCI forms of blind check, altogether blind check PDCCH 2*(4+2)=12 times; For the exclusive search volume of UE, the polymerization grade of CCE can be 1,2,4, and under corresponding CCE polymerization grade, PDCCH resource number is that { 6,6,2}, only needs the length of a kind of DCI form of blind check, and blind check is 6+6+2=14 time so altogether.Therefore, UE blind check number of times is altogether 12+14=26 time, and while adopting prior art frequently required 44 times, blind check number of times reduces greatly.
In sum, can find out and adopt the designed DCI form of the embodiment of the present invention can greatly reduce the number of times of UE blind check PDCCH, thereby greatly reduce the processing complexity of terminal, improve terminal processes speed, thereby reduce the cost of terminal.
