Title:
METHOD AND APPARATUS FOR DETECTING SIGNALS OF A DOWNLINK CONTROL CHANNEL IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/128468
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). The present disclosure discloses a method for detecting signals of a downlink control channel, including: determining, by a user equipment, an initial control resource set, and receiving common control information from resources specified in the initial control resource set before establishing a radio resource control (RRC) connection; after establishing the RRC connection, determining, by the user equipment, a first control resource set where a user-specific search space is located, and determining the user-specific search space from the first control resource set according to information sent by a base station and/or a user bandwidth capacity and/or a user service type; and detecting, by the user equipment, user control information in the user-specific search space determined. When the present disclosure is implemented, a lower transmission delay and higher transmission reliability can be achieved for a control channel.
