Title:
METHOD AND APPARATUS FOR CONTROL CHANNEL RECEPTION IN WIRELESS COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2020/197215
Kind Code:
A1
Abstract:
The 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 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. The disclosure discloses a signaling method and apparatus for properly increasing a control channel detection complexity of a terminal in order to efficiently detect a control channel for performing coordinated transmission such as non-coherent joint transmission (NC-JT).
