Title:
RADIO FREQUENCY LINK SWITCHING METHOD AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/109879
Kind Code:
A1
Abstract:
The present application provides a radio frequency link switching method and a communication device. The method comprises: a terminal device receives first information from a network device, the first information being used for instructing the terminal device to switch at least one transmitting link from a first carrier group to a second carrier group; the terminal device determines a third carrier group according to a first parameter of the first carrier group and a first parameter of the second carrier group, the third carrier group being the first carrier group or the second carrier group, the switching time of the transmitting link being in the third carrier group, and the first parameter comprising one or more of the following parameters: a carrier bandwidth of at least one carrier, a bandwidth part (BWP) in the at least one carrier, identification information of the at least one carrier, identification information of a cell to which the at least one carrier belongs, or the number of carriers. Resource waste can be reduced, and the resource utilization rate is improved.
