Title:
MULTICAST SERVICE MODIFICATION NOTIFICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/284376
Kind Code:
A1
Abstract:
The present application provides a multicast service modification notification method and a communication apparatus. The method comprises: a terminal device receives DCI and scheduling information from a network device, wherein the DCI comprises modification notification information which is used to indicate that M multicast services have changed, the scheduling information is carried on an MCCH, the scheduling information comprises P G-RNTIs and identifiers of the M multicast services, and one G-RNTI corresponds to a plurality of multicast services; the network device indicates, by means of the DCI, that the M multicast services have changed; If there is a service among the M multicast services that is of interest to the terminal device, the terminal device may re-acquire configuration information of the multicast service according to the scheduling information. Conversely, if the terminal device is not interested in the M multicast services, the terminal device does not need to re-acquire configuration information of a multicast service. In the foregoing manner, unnecessary power consumption and overhead can be avoided for the terminal device as much as possible.
