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).

Dependent claims

A method performed by a user equipment (UE), the method comprising:

receiving, from a base station, a radio resource control (RRC) message including first control information identifying a first index,
wherein the first index is mapped to a first offset, from among a plurality of possible offsets, in accordance with a table;
receiving, from the base station, a Physical Downlink Control Channel (PDCCH), which corresponds to one or more control channel element(s) (CCE(s)),
wherein a Downlink Control Information (DCI) format is carried in the PDCCH;
determining a number of resource blocks, based on a second index of a first CCE of the one or more CCE(s);
determining a first position of a resource block of a Physical Uplink Control Channel (PUCCH) transmission based on the first offset and the number of resource blocks;
and
performing the PUCCH transmission at the first position of the resource block,
wherein the PUCCH transmission includes Hybrid Automatic Repeat Request (HARQ)-Acknowledgement (ACK) information corresponding to the DCI format,
wherein the first position is located within an uplink bandwidth part,
wherein the first offset is independent of the second index,
wherein the first offset indicates a first distance between a boundary of the uplink bandwidth part and a second position, and
wherein the number of resource blocks indicates a second distance between the second position and the first position.
