Step 302:User equipment is according to first configured information, it is determined whether there is pairing user.
The beneficial effect of the above method provided in an embodiment of the present invention is：The first configured information is obtained from DCI by user equipment；First configured information is used to indicate whether the pairing user that there is user equipment；User equipment is according to the first configured information, it is determined whether there is pairing user；User equipment can be reduced the complexity of associated detecting method and the possibility of error, improve the detection efficiency of pairing user by the first configured information clearly with the presence or absence of pairing user.Example IV
The determination method of pairing user provided in an embodiment of the present invention by taking DCI format 2C under TM9 as an example, will be illustrated below, referring to Fig. 4, this method flow includes：
Step 401:User equipment receives DCI, and judges to whether there is the first configured information in DCI；If In the presence of then execution step 402, if being not present, exits this flow.
Wherein, first configured information is used to indicate whether the pairing user in the presence of the user equipment.
Specifically, user equipment obtains the DCI of PDCCH carryings by PDCCH blind checks.PDCCH blind checks include：First, the transmission mode that user equipment is issued in advance according to base station, in the corresponding relation of transmission mode-descending control information format（As shown in foregoing table 1）, obtain the corresponding all descending control information formats of transmission mode issued；Then, user equipment goes to receive PDCCH successively using each descending control information format, until eventually receiving PDCCH.This is well known in the art technology, will not be described in detail herein.
Specifically, as described in step 202 in the embodiment of the present invention two, when " Modulation and coding scheme " (the 4th subfield) ^ " Redundancy version " (the 6th subfield in transport block2 (the 3rd field)）When being configured for predetermined value, lbit (the 5th subfields that " New data indicator " takes）For idle bit（ one codeword ).First configured information can be arranged in the 5th subfield.It is on the contrary, when " Modulation and coding scheme " (the 4th subfield) and " Redundancy version " (the 6th subfield) is not configured for predetermined value in transport block2 (the 3rd field), the lbit (the 5th subfield) that " New data indicator " takes will no longer be idle bit（Two codeword), then, base station will be unable to the first configured information being arranged in DCI.Therefore, user equipment is received after DCI, should judge to whether there is the first configured information in DCI.Specifically, user equipment checks transport block2 (the 3rd fields）In " Modulation and coding scheme " (the 4th subfield）With " Redundancy version " (the 6th subfield）Whether it is predetermined value, if so, then judging there is the first configured information in DCI, if it is not, then judging the first configured information is not present in DCI.

403 include：
Step 4031:User equipment judges whether to match user according to the first configured information of acquisition, if there is pairing user, performs step 4032;If in the absence of pairing user, exiting this flow.
Specifically, when the first configured information is the first value, then it represents that there is the pairing user of user equipment；When the first configured information is second value, then it represents that in the absence of the pairing user of user equipment.
Specifically, according to the definition of LTE system, on identical running time-frequency resource between user equipment and pairing user Identical " Antenna port " and " scrambling identity " can not be used.Also, user equipment is only capable of selecting the combination of four kinds " Antenna port " and " scrambling identity " with pairing user on identical running time-frequency resource（As shown in table 3）.For example, it is assumed that the user equipment A being scheduled on a running time-frequency resource is configured with " 1 layer, port 7, nSCID=0 ", then user equipment A pairing user can use " port 7, n is not contained in table 2 on the running time-frequency resourceSCID=0 " the pairing user of configuration, i.e. user equipment A can use in foregoing table 2 " value 0 and 1 " under " value 1,2 and 3 " or " two codeword " under " one codeword ".It is worth noting that, " value 4 " that LTE system is defined under " one codeword " at present can not be paired user and use, therefore the embodiment of the present invention is put aside.
Table 3
