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 invention provides a communication method, device, equipment and system and a storage medium. The method comprises the following steps: terminal equipment sets N time parameters according to the Ntime parameters, and at least one target time parameter set is set, wherein the time unit lengths corresponding to at least two time parameter sets in the N time parameter sets are different; the terminal device determines M target times according to a first time and at least one target time parameter set, generates a codebook according to response information corresponding to downlink information received by at least one target time in the M target times, and sends the codebook to the network equipment at the first time. The network equipment determines whether the downlink information corresponding to the response information is successfully transmitted or not according to the response information included in the codebook. Thus, when the time unit lengths corresponding to at least two time parameter sets in the N time parameter sets are different, that the network equipment and the terminal equipment have consistent understanding on the codebook is ensured.

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...
