Apparatus and method of uplink control channel resource allocation for new radio

1. A method of transmitting uplink (UL) control information by a user equipment, the method comprising:

receiving, from a base station, UL control channel resource set configuration information for UL control information transmission;

determining one of UL control channel resource sets contained in the UL control channel resource set configuration information;

determining one of UL control channel resources contained in the determined UL control channel resource set; and

transmitting UL control information through the determined UL control channel resource,

wherein the UL control channel resource sets are configured for each UL bandwidth part (BWP) configured for the user equipment, and

wherein the each UL BWP is activated through downlink (DL) control information.

2. The method according to claim 1 , wherein the determining of the one of the UL control channel resource sets is performed based on a size of the UL control information.

3. The method according to claim 1 , further comprising receiving, from the base station, downlink (DL) control information containing information indicating the one of the UL control channel resources for the UL control information transmission,

wherein the one of the UL control channel resources is indicated from the base station through the DL control information.

4. A method of receiving uplink (UL) control information by a base station, the method comprising:

transmitting UL control channel resource set configuration information for transmitting UL control information to a user equipment; and

receiving the UL control information through one of UL control channel resources configuring one of UL control channel resource sets contained in UL control channel resource set configuration information,

wherein the UL control channel resource sets are configured for each UL bandwidth part (BWP) configured for the user equipment, and

wherein the each UL BWP is activated through downlink (DL) control information.

5. The method according to claim 4 , wherein the one of the UL control channel resource sets for the UL control information transmission is determined based on a size of the UL control information.

6. The method according to claim 4 , further comprising transmitting, to the user equipment, DL control information containing information that indicates the one of the UL control channel resources for the UL control information transmission,

wherein the one of the UL control channel resources is indicated to the user equipment through the DL control information.

7. A user equipment for transmitting uplink (UL) control information, comprising:

a receiver configured to receive, from a base station, UL control channel resource set configuration information for UL control information transmission;

a controller configured to determine one of UL control channel resource sets contained in the UL control channel resource set configuration information, and determine one of UL control channel resources configuring the determined one UL control channel resource set; and

a transmitter configured to transmit the UL control information through the determined UL control channel resource,

wherein the UL control channel resource sets are configured for each UL bandwidth part (BWP) configured for the user equipment, and

wherein the each UL BWP is activated through downlink (DL) control information.

8. The user equipment according to claim 7 , wherein the determining of the one of the UL control channel resource sets is performed based on a size of the UL control information.

9. The user equipment according to claim 7 , wherein the receiver receives, from the base station, DL control information containing information that indicates the one of the UL control channel resources for the UL control information transmission,

wherein the one of the UL control channel resources is indicated from the base station through the DL control information.
