COMMUNICATION METHOD, APPARATUS, AND DEVICE, AND READABLE STORAGE MEDIUM

WIPO Patent Application WO/2021/184223

A1

The present disclosure relates to the field of communications, and provides a communication method, apparatus, and device, and a readable storage medium. The method comprises: determining, from among at least two listen-before-speak (LBT) frequency bands, a first LBT frequency band on which channel monitoring is successful; and sending an uplink communication message on a first physical uplink control channel (PUCCH) on the first LBT frequency band. Channel monitoring is performed on at least two LBT frequency bands, thus a first LBT frequency band on which channel monitoring is successful is determined from among the at least two LBT frequency bands, and an uplink communication message is sent on a PUCCH of the first LBT frequency band. Thus, a high-priority HARQ-ACK message can occupy a channel by using a higher probability during transmission, thereby ensuring low-latency and high-reliability transmission of PUCCH channel information.
