Problems solved by technology

[0004] However, in order to ensure backward compatibility, the time unit corresponding to some feedback information will still be in the unit of slot. In this way, the length of the time unit corresponding to the feedback information will not be exactly the same. At this time, the HARQ_ACK codebook will not be generated.

Abstract

The present application provides a communication method, device, device, system and storage medium, the method comprising: the terminal device determines at least one target time parameter set according to N time parameter sets, at least two time parameter sets in the N time parameter sets The time unit lengths corresponding to the sets are different, the terminal device determines M target times according to the first time and at least one target time parameter set, and generates codebook, and send the codebook to the network device at the first time. The network device determines whether the downlink information corresponding to the response information is successfully transmitted according to the response information included in the codebook. In this way, when the time unit lengths corresponding to at least two time parameter sets in the N time parameter sets are different, it is ensured that the network device and the terminal device have a consistent understanding of the codebook.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a communication method, device, equipment, system and storage medium. Background technique [0002] During the communication process, after the terminal device receives the downlink data carried in the Physical Downlink Shared Channel (PDSCH), it will respond to it through Hybrid Automatic Repeat Request (HARQ) feedback according to the result of data decoding. Messages, that is, ACK (Acknowledgment) is fed back if data reception is successful, and NACK (No Acknowledgment) is fed back to network devices if data reception fails. A timing relationship is satisfied between when the terminal device receives downlink data and when the terminal device feeds back ACK / NACK to the network device. [0003] With the improvement of delay requirements, the feedback delay needs to be reduced, that is, the user can feed back the corresponding ACK / NACK as soon as possible a...
