Title:
COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/074530
Kind Code:
A1
Abstract:
This communication method is executed by a UE 100 in a mobile communication system that provides a multicast broadcast service (MBS). The communication method comprises: a step for receiving MBS signals transmitted from a plurality of cells constituting a single frequency network (SFN) by using the same identifier; a step for measuring reception quality of MBS signals by setting the MBS signals having the same identifier as measurement targets; and a step for reporting to the network a measurement result obtained in the measurement step.
