APPARATUS AND METHOD FOR SUPPORTING NETWORK ENTRY IN A MILLIMETER-WAVE MOBILE BROADBAND COMMUNICATION SYSTEM

摘要

A method performed by a base station to support network entry of a mobile station in a communication system, the method comprising: transmitting, to the mobile station, system information comprising random access configuration over each of a plurality of downlink, DL, transmission beams; receiving, from the mobile station, an initial random access signal based on the random access configuration, wherein the initial random access signal indicates a preferred DL beam from among the plurality of DL transmission beams; and transmitting a random access acknowledge signal in response to the initial random access signal based on the indicated preferred DL beam to the mobile station.
