METHOD AND APPARATUS FOR PROCESSING RANDOM ACCESS IN MOBILE COMMUNICATION SYSTEM

摘要

A base station transmits preamble information on each of plurality of beams to the plurality of beams. A terminal detects the preamble corresponding to a first beam transmitted by using the preamble information of the first beam through the first beam selected among the plurality of beams, and detects a beam of transmitting the preamble. After allocating the uplink resource of the detected beam, uplink approval including the uplink resource and the indicator of the detected beam is included in a response to the preamble. And, it is transmitted to a terminal. So, an effective random access can be carried out.
