Title:
METHOD AND DEVICE FOR RADIO RESOURCE ALLOCATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/091561
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An operation method of a base station in a radio communication system and an apparatus therefor are provided. The operation method includes transmitting, to a terminal, configuration information including a configuration of a bandwidth part in an unlicensed spectrum, the bandwidth part including a plurality of subbands, performing a channel access procedure for each of the plurality of subbands included in the bandwidth part, initiating channel access via at least one subband, among the plurality of subbands, determined to be an idle channel according to a result of the channel access procedure, transmitting, to the terminal, the result of the channel access procedure for each subband, among the plurality of subbands, and transmitting, to the terminal, a data channel according to the result of the channel access procedure for each subband, among the plurality of subbands.
