Abstract

The embodiment of the invention provides a priority updating method, device and system, relates to the technical field of communication, and aims to solve the problem of poor data transmission performance of UE due to the fact that the UE cannot transmit high-priority data in time after monitoring a channel for a long time. The method comprises the following steps: under the condition the first channel access priority is higher than the second channel access priority, updating the second channel access priority stored in the UE to the first channel access priority, the first channel access priority being the channel access priority corresponding to the first data to be sent, and the second channel access priority being the channel access priority indicated by the network device to the UE.The method is applied to a scene in which the UE transmits data.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a priority updating method, device and system. Background technique [0002] Currently, channel access priority classes (channel access priority classes, CAPC) in a wireless communication system include four kinds of channel access priorities. These four channel access priorities may be used when a user equipment (user equipment, UE) performs data transmission on a license assisted access (LAA) carrier. [0003] In a new radio in unlicensed band (NR-U) scenario based on an unlicensed frequency band, before data transmission, the UE may preempt the channel according to the channel access priority indicated to the UE by the network device. Specifically, the UE can perform channel monitoring according to the channel access priority to determine whether the channel is idle; if the channel is idle, the UE can perform data transmission on the ch...
