通過(guò)接收反饋，根據(jù)不同的反饋方式分別加以判斷：
【1】bundling ：
TDD ACK/NACK bundling is performed per codeword across multiple DL subframes associated with a single UL subframe n, where is the number of elements in the set defined in Table 10.1-1, by a logical AND operation of all the individual PDSCH transmission (with and without corresponding PDCCH) ACK/NACKs and ACK in response to PDCCH indicating downlink SPS release. For one configured serving cell the bundled 1 or 2 ACK/NACK bits are transmitted using PUCCH format 1a or PUCCH format 1b, respectively.
【2】multiplexing ：
For TDD ACK/NACK multiplexing and a subframe n with , where is the number of elements in the set defined in Table 10.1-1, spatial ACK/NACK bundling across multiple codewords within a DL subframe is performed by a logical AND operation of all the corresponding individual ACK/NACKs. PUCCH format 1b with channel selection is used in case of one configured serving cell. For TDD ACK/NACK multiplexing and a subframe n with , spatial ACK/NACK bundling across multiple codewords within a DL subframe is not performed, 1 or 2 ACK/NACK bits are transmitted using PUCCH format 1a or PUCCH format 1b, respectively for one configured serving cell.
