Title:
METHOD AND APPARATUS FOR EFFICIENTLY OPERATING DORMANT BANDWIDTH PART IN NEXT GENERATION MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/010759
Kind Code:
A1
Abstract:
The disclosure relates to a communication technique for combining a 5G communication system with an IoT technology to support a higher data transmission rate than a 4G system, and a system thereof. The disclosure may be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety, etc.) based on a 5G communication technology and an IoT-related technology. In an embodiment of the disclosure, a method performed by a terminal in a wireless communication system is provided. The method comprises: receiving, from a base station, a radio resource control (RRC) message including information on an identifier to indicate a secondary cell (Scell), information on at least one bandwidth part (BWP) of the Scell, and information including first information on a first BWP to be used as dormant BWP among the at least one BWP and second information on a second BWP to be activated as non-dormant BWP from dormant BWP; receiving, from the base station, downlink control information (DCI) including a bitmap associated with a BWP activation of the Scell; and activating a BWP identified based on the identifier, the bitmap, and at least one of the first information or the second information. According to the disclosure, via a method by which a new dormant (or hibernation) mode may be operated in units of bandwidth parts (bandwidth part-level), a carrier aggregation technology can be rapidly activated, and a battery of a terminal can be saved.
