Description

Transmission method, terminal, network equipment and storage medium of feedback response information

Technical Field

The present invention relates to wireless communication technologies, and in particular, to a transmission method, a terminal, a network device, and a storage medium for feedback response information.

Background

An uplink subframe of a time division duplex long term evolution (LTE TDD) system may carry acknowledgement/negative feedback (ACK/NACK) information, i.e., multi-bit ACK/NACK information, corresponding to a Physical Downlink Shared Channel (PDSCH) transmitted in a plurality of Downlink subframes. When the terminal is limited in transmission power and cannot transmit multi-bit ACK/NACK information, the ACK/NACK information is transmitted by using a feedback acknowledgement information combining (ACK/NACK bundling) mode. The ACK/NACK bundling is to perform logic and operation processing on multi-bit ACK/NACK information to obtain 1-bit merging information, and the merging rule is as follows: when any bit in the multi-bit ACK/NACK information represents NACK information, combining the information into the NACK information; when all the multi-bit ACK/NACK information is ACK information, the combined information is the ACK information. The use of ACK/NACKbundling can effectively improve the coverage of the uplink control channel, but can reduce the downlink transmission efficiency, that is, any PDSCH is transmitted incorrectly, and multiple PDSCHs need to be retransmitted.

In the 5G system, due to supporting technologies such as a dynamic Hybrid Automatic repeat request (HARQ) timing, a CBG-based transmission, and the like, the number of ACK/NACK bits carried in one uplink control channel may be large. In order to ensure uplink coverage, the ACK/NACK bundling scheme is continuously used. However, how to guarantee uplink coverage while considering downlink transmission efficiency is a problem to be solved.

Scene one

The network device determines the merged granularity by a configuration mode or a protocol convention mode, for example, the merged granularity respectively includes 1, 2, 4, and all; wherein, the merged granularity of 1 indicates no merging; the combination granularity is 2, which indicates that the adjacent 2-bit ACK/NACK information is combined; the merging granularity is 4, which indicates that adjacent 4-bit ACK/NACK information is merged; the combining granularity of all indicates that all multi-bit ACK/NACK information is combined. And the terminal receives DCI sent by the network equipment, the DCI indicates one of the four merging granularities, and the terminal merges multi-bit ACK/NACK information to be sent according to the indicated merging granularity.

When the terminal is configured in the single codeword transmission mode, that is, each Physical Downlink Shared Channel (PDSCH) includes at most one Transport Block (TB). Assuming that the terminal receives 6 PDSCHs and the corresponding ACK/NACK information is transmitted through the same channel, then:

When the combined bit length is 4, referring to fig. 2f, b0, b1, b2, b3, b4, and b5 are combined into 4-bit ACK/NACK information, b0 and b1 are combined into b '0, b2 and b3 are combined into b' 1, b4 and b5 do not match, b4 and b5 correspond to b '2 and b' 3, respectively, and the transmission information is combined into combined { b '0, b' 1, b '2, b' 3}, with reference to a uniform combination rule that the absolute value of the difference between the number of feedback response information bits included in each set of feedback response information and the number of feedback response information bits included in other sets of feedback response information in the N sets after combination is not greater than 1.

When the bit length after combining is all, it indicates that the feedback response information is not combined, as shown in fig. 2a, the transmission information is { b0, b1, b2, b3, b4, b5}, where b0, b1, b2, b3, b4, and b5 indicate ACK/NACK information corresponding to each channel, that is, ACK/NACK information corresponding to the transmission through 6 PDSCHs.
