Title:
APPARATUS AND METHOD FOR MANAGING UPLINK CONTROL CHANNELS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/251326
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 apparatus and a method for managing uplink control channels in a wireless communication system are provided. The operating method of a base station includes transmitting configuration information for a carrier aggregation (CA) operation using a first carrier and a second carrier, and transmitting a message for activation or deactivation of an uplink control channel in the second carrier based on an electric field strength of a channel with a terminal or a location of the terminal during the CA operation according to the configuration information.
