By taking Fig. 2 c as an example, if this block control resource just falls in the network equipment and can be used for terminal equipment configuration at this time In the resource collection for transmitting descending scheduling data, and the network equipment passes through this resource set of Downlink Control Information instruction terminal equipment The downlink data for being used to transmitting and scheduling is closed, the downlink data of scheduling does the figure of rate-matched to the Downlink Control Information for dispatching it Case can be misread by terminal device, influence the accuracy to scheduling downlink data decoding, as shown in Figure 2 e, terminal device thinks downlink Data portion does not include rear 8 CCE, and the network equipment is utilized 16 CCE and carries out downlink data transmissions, will lead to terminal in this way Equipment leads to Physical Downlink Shared Channel (Physical due to missing mass data when decoding to data Downlink Shared Channel, PDSCH) decoding failure.Conversely, when the network equipment sends downlink control with polymerization grade 8 When information, terminal device so also may can misunderstand to rate-matched pattern, be caused with 16 decoding success of polymerization grade PDSCH decoding failure.

For the polymerization grade for solving the problems, such as the possible error understanding Physical Downlink Control Channel of terminal device, the application is implemented A kind of possible thinking that example provides are as follows: using the bit block being mapped to when polymerization grade 16 in preceding 8 control channel elements, no It is same as using the bit block being mapped to when polymerization grade 8 in 8 control channel elements, to solve in the situation that Fig. 2 c is illustrated The problem of the causing that understand differently of terminal device and the network equipment to polymerization grade；Alternatively, using after being mapped to when polymerization grade 16 8 Bit block in a control channel element, the bit being mapped to when different from the use of polymerization grade 8 in 8 control channel elements Block, to solve the problems, such as that terminal device and the network equipment cause understanding differently for polymerization grade in situation that Fig. 2 d is illustrated.

Based on this, implementation in the embodiment of the present application can there are many, the various modifications mode based on above-mentioned thinking Within that scope of the present invention.Illustratively, the first possible implementation are as follows: the network equipment using polymerization grade 1, 2, it when 4,8 transmission Physical Downlink Control Channel, is executed according to the process that Fig. 2 a is illustrated；And it is sent using polymerization grade 16 When Physical Downlink Control Channel, shifting function is carried out to the bit block being mapped in 16 control channel elements, for example, in rate Shifting function is carried out after matching, before scrambling to bit block.Second of possible implementation: the network equipment uses polymerization etc. When any polymerization grade in grade 1,2,4,8,16 sends Physical Downlink Control Channel, to being mapped to respective physical control channel In bit block carry out shifting function, and polymerization grade 8 is different with polymerization grade 16 corresponding shifting function (for example, displacement behaviour What is shifted in work is of different sizes).
