Title:
COMMUNICATION METHOD AND DEVICE BASED ON COMMON FREQUENCY RESOURCE FOR GROUP COMMON TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/240182
Kind Code:
A1
Abstract:
Disclosed are: a configuration for a common frequency resource for group common transmission in a wireless communication system; and a communication method and device based thereon. A method by which a terminal receives group common data in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving, from a network, configuration information about a common frequency resource (CFR) for group common data associated with a group common identifier; receiving, from the network, information about a first bandwidth part (BWP) from among a plurality of BWPs; receiving, from the network, group common data based on the group common identifier on a bandwidth of a first BWP including the CFR; receiving, from the network, information about a second BWP from among the plurality of BWPs; activating the second BWP; and receiving, from the network, group common data based on the group common identifier on a bandwidth of the second BWP, on the basis of the satisfaction of a specific condition between the second BWP and the CFR.
