Abstract
The disclosure relates to technology for identifying a user equipment beam index in a base station. The base station indicates one or more resources assigned to the user equipment within a beam failure random access channel (BRACH) resource, and transmits one or more synchronization signal block resources and one or more new beam identification reference signal resources to the user equipment. The base station then receives one of the resources from a group of the one or more resources within the BRACH resource assigned to the user equipment corresponding to the BRACH resource, and identifies a preferred beam index of the user equipment based on information in the BRACH resource and the received one of the resources.
