UE INITIATED DISCOVERY IN ASSISTED MILLIMETER WAVELENGTH WIRELESS ACCESS NETWORKS

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE transmits a beamformed broadcast request signal to a base station in a plurality of transmissions in transmit spatial directions of the UE, receives a beamformed broadcast response signal from the base station in a resource of a plurality of resources, and determines a preferred transmit spatial direction of the UE based on the resource in which the beamformed broadcast response signal is received. The apparatus may be a base station. The base station scans for a beamformed broadcast request signal from a UE, determines a preferred transmit spatial direction of transmit spatial directions of the UE, determines a resource of a plurality of resources for indicating the determined preferred transmit spatial direction, and transmits a beamformed broadcast response signal to the UE in the determined resource.
