Abstract

The present disclosure discloses a method, a user equipment and a base station for transmitting HARQ-ACK information, including: determining, the number of bits of HARQ-ACK information transmitted on an uplink subframe n and a PUCCH resource for transmitting the HARQ-ACK information; determining, a PUCCH power adjustment value transmitting the HARQ-ACK information according to a shared field of TPC and a total DL DAI in DCI of a PDCCH scheduling a PDSCH or indicating semi-static SPS release; transmitting, the HARQ-ACK information on the uplink subframe n according to the determined number of bits, the PUCCH resource, and the PUCCH power adjustment value; wherein the shared field of the TPC and the total DL DAI is just used to transmit a TPC command, or, the shared field of the TPC and the total DL DAI is used to transmit the TPC command or a value of the total DL DAI.

First claim

What is claimed is:

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a higher-layer signaling including information related to hybrid automatic repeat request-acknowledgement (HARQ-ACK) information for a cell group of a serving cell;
receiving, from the base station, a physical downlink control channel (PDCCH) including downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH);
obtaining first HARQ-ACK information for a first subgroup of the cell group based on a first manner;
and second HARQ-ACK information for a second subgroup of the cell group based on a second manner based on the higher-layer signaling;
obtaining third HARQ-ACK information based on the first HARQ-ACK information and the second HARQ-ACK information;
identifying resource for a physical uplink control channel (PUCCH) based on a resource set for the PUCCH and a field indicating PUCCH resource included in the DCI; and
transmitting, to the base station, the PUCCH including the third HARQ-ACK information based on the resource for the PUCCH,
wherein in case that a number of bits of the third HARQ-ACK information is less than or equal to 2, a first PUCCH resource set is used for the PUCCH,
wherein in case that the number of bits of the third HARQ-ACK information is greater than 2, a second PUCCH resource set is used for the PUCCH, and
wherein the field indicating the PUCCH resource is different from a transmission power control (TPC) field for the PUCCH included in the DCI.

2. The method of claim 1 , wherein the information related to HARQ-ACK information indicates the first manner or the second manner.

3. The method of claim 1 , further comprising:
determining a PUCCH power adjustment value for the third HARQ-ACK information based on the TPC field included in the DCI.

4. The method of claim 1 , further comprising:
semi-statically determining a set of all of downlink timeslots that need to transmit the HARQ-ACK information on an uplink subframe.

5. The method of claim 1 , wherein the first HARQ-ACK information is determined semi-statically based on the first manner and the second HARQ-ACK information is determined dynamically based on the second manner.

6. The method of claim 1 , wherein the number of bits of the third HARQ-ACK information is a sum of a number of bits of the first HARQ-ACK information and a number of bits of the second HARQ-ACK information.
