Description

Method for transmitting feedback response information, terminal, network device and storage medium

Technical field

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

Background technique

An uplink subframe of a Time Division Duplex Long Term Evolution (LTE TDD) system carries a positive feedback response/negative feedback response (ACK) corresponding to a Physical Downlink Shared Channel (PDSCH) transmitted in multiple downlink subframes. /NACK) information, that is, multi-bit ACK/NACK information. When the terminal transmission power is limited and the multi-bit ACK/NACK information cannot be transmitted, the ACK/NACK information is transmitted by using ACK/NACK bundling. ACK/NACK bundling is a logical AND operation of multi-bit ACK/NACK information to obtain 1-bit merge information. The merge rule is: when any bit in the multi-bit ACK/NACK information indicates NACK information, the merge information is NACK. Information; when the multi-bit ACK/NACK information is all ACK information, the merge information is ACK information. The ACK/NACK bundling can effectively improve the coverage of the uplink control channel, but it will reduce the downlink transmission efficiency, that is, any PDSCH transmission error, and multiple PDSCHs need to be retransmitted.

In the 5G system, the number of ACK/NACK bits carried in one uplink control channel may be large due to the support of Hybrid Automatic Repeat reQuest (HARQ) timing and CBG-based transmission. In order to guarantee uplink coverage, the ACK/NACK bundling scheme will continue to be used. However, how to ensure the uplink coverage while taking into account the downlink transmission efficiency is a problem that needs to be solved.
