METHOD AND APPARATUS FOR TRANSMITTING CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of transmitting a control channel by a Base Station (BS), the method comprising:
- receiving, from a User Equipment (UE) through at least one first beam, Beam State Information (BSI);
identifying a second beam, based on the BSI;
transmitting, to the UE through the second beam, a first BSI request;
identifying a third beam, based on information on the at least one first beam; and
determining whether to transmit, to the UE through the third beam, the control channel.

Abstract
Provided are a method and a Base Station (BS) for transmitting a control channel and a method and a User Equipment (UE) for receiving a control channel in a wireless communication system. The BS includes: a transceiver; and at least one processor configured to control the transceiver to receive Beam State Information (BSI) from the UE through at least one first beam, identify a second beam, based on the BSI, and control the transceiver to transmit a first BSI request to the UE through the second beam, identify a third beam, based on information on the at least one first beam, and determine whether control the transceiver to transmit the control channel to the UE through the third beam.
