Abstract

The present disclosure relates to a feedback method, a feedback device and a storage medium. The feedback method applied to the terminal, the terminal maintains the codebook to be fed back, including: determining the queue of the codebook to be fed back according to the trigger indication sent by the network device, and the trigger indication is used to indicate whether the feedback code has been successfully received and feeding back the codebooks to be fed back in the queue of the codebooks to be fed back. The feedback method applied to a network device, wherein the network device maintains information about a codebook to be fed back by a terminal, including: determining whether the codebook fed back by the terminal is successfully received; The terminal updates the codebook information to be fed back; and sends a trigger indication to the terminal to indicate whether the codebook fed back by the terminal is successfully received. The feedback delay can be reduced through the present disclosure.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a feedback method, a feedback device and a storage medium. Background technique [0002] The increase in mobile devices and the rapid development of the mobile Internet have brought about explosive growth in mobile data, and put forward higher requirements for traffic density, network capacity, user rate, and delay. In order to meet the challenges, the fifth-generation mobile communication (5th generation, 5G) new air interface (New Radio, NR) has carried out a new air interface design for new scenarios and new frequency bands. On the other hand, the shortage of spectrum resources is an increasingly severe reality faced by mobile communication networks. Licensed frequency bands, especially low-frequency band resources with high value, not only have limited bandwidth, but are also being rapidly consumed by the growing terminal group. In order to meet the chal...
