Title:
MBS DATA CONTROL METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/197080
Kind Code:
A1
Abstract:
The present disclosure relates to a technology by which a terminal processes multicast/broadcast service (MBS) data in an NR-based mobile communication network. In one aspect, the present embodiments may provide a method and a device, the method, by which a terminal receives MBS data, comprising the steps of: receiving an RRC message from a base station; configuring a data inactivity timer on the basis of the RRC message; and when an MAC entity receives an MBS Traffic channel (MTCH) MAC SDU for the MBS, starting or restarting the data inactivity timer.
