Title:
METHOD AND APPARATUS USED IN WIRELESS COMMUNICATION NODE
Document Type and Number:
WIPO Patent Application WO/2021/208873
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus used in a wireless communication node. A first node receives first configuration information, the first configuration information being not unicast information and indicating K sub-bearers, wherein K is a positive integer greater than 1; for any higher layer data packet transmitted by means of the K sub-bearers respectively, the any higher layer data packet has an identical serial number in the K sub-bearers; a first sub-bearer is one of the K sub-bearers, and the higher layer data packet transmitted in any of the K sub-bearers is transmitted by means of the first sub-bearer. The present application enables a user to obtain, by means of broadcast, configuration information of a sub-bearer which transmits an identical MBMS service on different nodes or different CGs, so as to obtain the identical MBMS service simultaneously by means of a plurality of different nodes, thereby effectively reducing service interruptions caused by a movement between nodes.
