Fig. 4 shows the realization flow of PDCCH Adaptive Transmission processing method provided by the invention, as shown in Figure 4:
Step S401, user is detected in the DTX information of current TTI in base station, if if user does not receive DCI1 and do not carry out the feedback of ACK/NACK or user does not receive DCI0 and do not send PUSCH, then base station will detect the DTX information of user.
Step S402, according to the result of step S401, judges whether DTX information user being detected, if base station detects the DTX information of this user in current TTI, then enter step S403, if base station does not detect the DTX information of this user in current TTI, then enter step S404.
Step S403, the outer shroud factor D eltaCCEdB of base station to this user increase by one and raise step-length StepUp, and formula is as follows:
DeltaCCEdB＝DeltaCCEdB+StepUp (1)
Step S404, the outer shroud factor D eltaCCEdB of base station to this user reduce one and lower step-length StepDown, and formula is as follows:
DeltaCCEdB＝DeltaCCEdB-StepDown (2)
In step S403 and step S404, target BLER is made to be TargetBler, raise step-length StepUp and lower step-length StepDown and TargetBler and can obtain according to certain relation, such as can according to relational expression StepUp: StepDown=(1-TargetBler): TargetBler obtains, if TargetBler is 1%, then StepUp: StepDown=(1-TargetBler): TargetBler=99: 1, wherein the value of StepUp can not more than 3dB.
Step S405, base station is according to outer shroud factor D eltaCCEdB, and the PDCCH distribution for user meets the CCE resource of target BLER.
Be specially: the dB value of each CCE degree of polymerization in the set of the CCE degree of polymerization is determined according to the CCE degree of polymerization CCEinit that this user initially uses in base station, wherein, CCEinit is 0dB.Such as, make the set of the CCE degree of polymerization for 1,2,4,8}, CCEinit is 8, then the CCE degree of polymerization 1 is-9dB, and the CCE degree of polymerization 2 is-6dB, and the CCE degree of polymerization 4 is-3dB, and the relational expression of the dB value PDCCHres of CCE degree of polymerization CCEalloc and the CCE degree of polymerization is as follows:
