Title:
METHOD AND APPARATUS FOR DEACTIVATING AND ACTIVATING SECONDARY BASE STATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/060189
Kind Code:
A1
Abstract:
The present disclosure relates to: a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure relates to a method performed by a terminal in a wireless communication system, and may comprise the steps of: receiving a deactivation command regarding a secondary cell group (SCG) from a first base station related to a master cell group (MCG); performing measurement on at least one beam related to the SCG, in a deactivated state regarding the SCG; and performing a random access with a second base station related to the SCG, on the basis of a random access preamble related to a downlink beam, when beam failure is detected on the basis of the measurement.
