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).
Claims23
A user equipment (UE) comprising:
- a transceiver;
- and
- a controller,
- wherein the transceiver is configured to receive, from a base station:
- first control information indicating a first index through radio resource control (RRC) signaling;
- and
- a Physical Downlink Control Channel (PDCCH) in a resource which corresponds to one or more control channel element(s) (CCE(s)),
- wherein the controller is configured to determine, based on the first index, a first offset value corresponding to a first distance between a starting position of an uplink bandwidth part and a second position within the uplink bandwidth part in frequency domain, the first offset value being one of a plurality of candidate values,
- wherein the controller is configured to:
- determine, based on a second-index of a first CCE of the one or more CCE(s), a number of resource blocks;
- and
- determine a first position of a resource block of a Physical Uplink Control Channel (PUCCH) transmission based on the first offset value and the number of resource blocks, wherein the number of resource blocks indicates a second distance between the second position and the first position, and
- wherein the transceiver is configured to performing the PUCCH transmission, including Hybrid Automatic Repeat Request (HARD)-Acknowledgement (ACK) information, in response to the receiving of the PDCCH.
