Title:
METHOD AND APPARATUS FOR SUBBAND BASED CHANNEL ACCESS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/096434
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A base station and a terminal that perform communication using an unlicensed band may divide a bandwidth part into a plurality of subbands and may perform a channel access procedure for the respective subbands. A method for configuring a size of the subband and a method for configuring start/end frequency locations of the configured subband in order to perform the channel access procedure more efficiently in a communication system having various bandwidth sizes and subcarrier spacings. Further, according to the disclosure, a method by a terminal in a wireless communication system includes receiving configuration information of a bandwidth part from a base station; receiving subband configuration information from the base station; receiving control information including a result of a channel access procedure performed for each subband and resource allocation information; and receiving data based on the result of the channel access procedure and the resource allocation information.
