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 based on a rate of data reception from the UE through the at least one first beam being less than or equal to a first threshold value or based on a reception performance using the at least one first beam being less than or equal to a second threshold value.

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.

11. A Base Station (BS) for transmitting a control channel, the BS comprising:
-
a transceiver; and at least one processor configured to; control the transceiver to receive, from a User Equipment (UE) through at least one first beam, Beam State Information (BSI), identify a second beam, based on the BSI, control the transceiver to transmit, to the UE through the second beam, a first BSI request, identify a third beam, based on information on the at least one first beam, and determine whether to control the transceiver to transmit, to the UE through the third beam, the control channel based on a rate of data reception from the UE through the at least one first beam being less than or equal to a first threshold value or based on a reception performance using the at least one first beam being less than or equal to a second threshold value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of receiving a control channel by a User Equipment (UE), the method comprising:
-
transmitting, to a Base Station (BS) through at least one first beam, Beam State Information (BSI); receiving, from the BS through a second beam, a BSI request; and receiving, from the BS through a third beam, the control channel, wherein the second beam is identified based on the BSI and the third beam is identified based on information on the at least one first beam, and wherein the control channel is transmitted in case that a rate of data reception from the UE through the at least one first beam is less than or equal to a first threshold value or in case that a reception performance using the at least one first beam is less than or equal to a second threshold value.

22. A User Equipment (UE) for receiving a control channel, the UE comprising:
-
a transceiver; and at least one processor configured to; control the transceiver to transmit, to a Base Station (BS) through at least one first beam, Beam State Information (BSI), control the transceiver to receive, from the BS through a second beam, a BSI request, and control the transceiver to receive, from the BS through a third beam, the control channel, wherein the second beam is identified based on the BSI and the third beam is identified based on information on the at least one first beam, and wherein the control channel is transmitted in case that a rate of data reception from the UE through the at least one first beam is less than or equal to a first threshold value or in case that a reception performance using the at least one first beam is less than or equal to a second threshold value.
