Beam reporting method and apparatus in next generation wireless system

摘要

The present disclosure relates to a communication method and system for fusion of a 5G (5G) communication system supporting a higher data rate than a 4G (4G) system using the Internet of Things (IOT) technology. The present disclosure can be applied to intelligent services based on 5G communication technology and IoT related technologies such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a user equipment (UE) for multi-beam operation in a wireless communication system is provided. The method includes receiving setting information for a search space to receive a response to a beam failure recovery request from a base station (BS), at least included in the first set of reference signals to detect a beam failure event based on a threshold value Monitoring the channel state information reference signal (CSI-RS), when the beam failure event is detected, the reference signal received power (RSRP) or synchronization signal/physical broadcasting channel of the CSI-RS in the second set of reference signals ( Measuring at least one of the RSRP of the SS/PBCH) block, identifying a new candidate beam based on the measured RSRP, and recovering a beam failure through a physical random access channel (PRACH) based on detection of a beam failure event And sending the request to the BS.
