Description

Method, device and medium for receiving and transmitting uplink channel configuration information

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a storage medium for receiving and transmitting uplink channel configuration information.

Background

In a wireless communication system, such as a 5G New Radio (NR) communication system, downlink data is carried on a physical downlink shared channel (physical downlink shared channel, PDSCH) and uplink data is carried on a physical uplink shared channel (physical uplink shared channel, PUSCH). The base station apparatus schedules PDSCH and PUSCH by downlink control information (downlink control information, DCI) carried on a physical downlink control channel (physical downlink control channel, PDCCH).

In a scenario where NR 52.6-71GHz corresponds to unlicensed spectrum, the sender may follow a listen before talk (listen before talk, LBT) channel access (channel access) mechanism on unlicensed spectrum. In the LBT mechanism, the transmitting end needs to listen to the channel for clear channel detection (clear channel assessment, CCA). After CCA, the transmitting end occupies a free channel to transmit data, and the channel cannot be occupied when the channel is not free. The maximum duration (maximum channel occupy time, MCOT) that the sender occupies the channel is agreed by the protocol or the base station configuration/indication.

In some scenarios, the sender may not need to perform LBT before sending the data, but rather perform contention-free transmission (contention exemption transmission, CET). How to determine whether the uplink channel can go to CET is a problem to be solved.
