Title:
COMMUNICATION CONTROL METHOD AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2022/211127
Kind Code:
A1
Abstract:
A communication control method according to a first aspect of the present invention is used in a mobile communication system that provides a multicast and broadcast service (MBS) from a base station to a user device. Said communication control method comprises: broadcasting an MBS system information block by the base station; and transmitting, by the base station, MBS traffic channel scheduling information through an MBS control channel. The MBS system information block includes a search space identifier for reception of the MBS control channel by the user device. The search space identifier indicates a search space that is a resource range to be decoded by the user device in a physical downstream link control channel associated with the MBS control channel.
