Abstract
In order for a first terminal apparatus to transmit a physical uplink control channel to a base station without retuning regardless of a bandwidth part used by the first terminal apparatus, a base station 100 according to the present disclosure includes a communication processing unit 141 configured to communicate with the first terminal apparatus (terminal apparatus 200A) within a bandwidth part of an uplink system band, the bandwidth part being used by the first terminal apparatus (terminal apparatus 200A), wherein the bandwidth part includes a physical uplink control channel region used by the first terminal apparatus (terminal apparatus 200A).

1-51. (canceled)
A user equipment (UE) comprising:
- a transceiver configured to communicate with a base station in an active uplink bandwidth part;
- and
- a controller,
- wherein:
- the transceiver is configured to receive, from the base station, first control information indicating an index through radio resource control (RRC) signaling;
- the controller is configured to determine, based on the first control information, a first resource starting from a position corresponding to an offset corresponding to the index, the offset being included in a plurality of candidate offsets relative to an edge of the active uplink bandwidth part in frequency direction within the active uplink bandwidth part;
- the transceiver is configured to receive second control information from the base station through downlink control information (DCI);
- the controller is configured to determine, based on the second control information, a relative physical resource block (PRB) within the first resource;
- and
- the transceiver is configured to transmit a physical uplink control channel in a second resource corresponding to the relative PRB.
A base station comprising:
- a transceiver configured to communicate with a user equipment (UE) in an active uplink bandwidth part;
- and
- a controller,
- wherein:
- the transceiver is configured to transmit, to the UE, first control information indicating an index through radio resource control (RRC) signaling,
- a first resource starting from a position corresponding to an offset corresponding to the index is determined by the UE based on the first control information, the offset being included in a plurality of candidate offsets relative to an edge of the active uplink bandwidth part in frequency direction within the active uplink bandwidth part;
- the transceiver is configured to transmit second control information to the UE through downlink control information (DCI),
- a relative physical resource block (PRB) within the first resource is determined by the UE based on the second control information;
- and
- the transceiver is configured to receive a physical uplink control channel in a second resource corresponding to the relative PRB.
A method performed by a user equipment (UE), the method comprising:
- communicating with a base station in an active uplink bandwidth part;
- receiving, from the base station, first control information indicating an index through radio resource control (RRC) signaling;
- determining, based on the first control information, a first resource starting from a position corresponding to an offset corresponding to the index, the offset being included in a plurality of candidate offsets relative to an edge of the active uplink bandwidth part in frequency direction within the active uplink bandwidth part;
- receiving second control information from the base station through downlink control information (DCI);
- determining a relative physical resource block (PRB) within the first resource based on the second control information;
- and
- transmitting a physical uplink control channel in a second resource corresponding to the relative PRB.
