Abstract

Official abstract text for this publication.

A terminal device receives a DCI format triggering a Type-3 HARQ-ACK codebook; and transmission circuitry configured to transmit the Type-3 HARQ-ACK codebook via a first PUCCH indicated by the DCI format; wherein the first PUCCH is associated with a first priority index; wherein the first priority index is indicated by the DCI format, or is configured by a RRC parameter, or is predetermined.

First claim

Opening claim text (preview).

The invention claimed is: 1. A terminal device comprising: reception circuitry configured to and/or programmed to receive a first DCI format and a second DCI format, wherein the first DCI format schedules a first PDSCH, the first PDSCH corresponding to HARQ-ACK information of a first priority index, and the second DCI format schedules a second PDSCH and includes a One-shot HARQ-ACK request field indicating 1, the second PDSCH corresponding to HARQ-ACK information of a second priority index, and transmission circuitry configured to and/or programmed to transmit a Type-3 HARQ-ACK codebook including the HARQ-ACK information corresponding to each of the first PDSCH and the second PDSCH, wherein a priority index of the Type-3 HARQ-ACK codebook is the second priority index indicated by the second DCI format. 2. A base station device comprising: transmission circuitry configured to and/or programmed to transmit a first DCI format and a second DCI format, wherein the first DCI format schedules a first PDSCH, the first PDSCH corresponding to HARQ-ACK information of a first priority index, and the second DCI format schedules a second PDSCH and includes a One-shot HARQ-ACK request field indicating 1, the second PDSCH corresponding to HARQ-ACK information of a second priority index, and reception circuitry configured to and/or programmed to receive a Type-3 HARQ-ACK codebook including the HARQ-ACK information corresponding to each of the first PDSCH and the second PDSCH, wherein a priority index of the Type-3 HARQ-ACK codebook is the second priority index indicated by the second DCI format. 3. A communication method used by a terminal device, the communication method comprising: receiving a first DCI format and a second DCI format, wherein the first DCI format schedules a first PDSCH, the first PDSCH corresponding to HARQ-ACK information of a first priority index, and the second DCI format schedules a second PDSCH and includes a One-shot HARQ-ACK request field indicating 1, the second PDSCH corresponding to HARQ-ACK information of a second priority index, and transmitting a Type-3 HARQ-ACK codebook including the HARQ-ACK information corresponding to each of the first PDSCH and the second PDSCH, wherein a priority index of the Type-3 HARQ-ACK codebook is the second priority index indicated by the second DCI format.
