Abstract
A method and apparatus for transmitting, by a user equipment, a hybrid automatic repeat request acknowledgement (HARQ-ACK) are provided. The method includes identifying power of the HARQ-ACK based on transmission power control information in first downlink control information for a primary cell; identifying, for a time division duplexing (TDD) and a plurality of configured cells, a resource for transmission of the HARQ-ACK based on transmission power control information in second downlink control information with a downlink assignment index (DAI) value greater than 1; and transmitting the HARQ-ACK based on the resource on the primary cell.
Claims20
A method for transmitting, by a user equipment, a hybrid automatic repeat request acknowledgement (HARQ-ACK), the method comprising:
- identifying power of the HARQ-ACK based on transmission power control information in first downlink control information for a primary cell;
- identifying, for a time division duplexing (TDD) and a plurality of configured cells, a resource for transmission of the HARQ-ACK based on transmission power control information in second downlink control information with a downlink assignment index (DAI) value greater than 1;
- and
- transmitting the HARQ-ACK based on the resource on the primary cell.
A method for receiving, by a user equipment, a hybrid automatic repeat request acknowledgement (HARQ-ACK), the method comprising:
- transmitting transmission power control information in first downlink control information for a primary cell for power of the HARQ-ACK;
- transmitting, for a time division duplexing (TDD) and a plurality of configured cells, transmission power control information in second downlink control information with a downlink assignment index (DAI) value greater than 1 for a resource for transmission of the HARQ-ACK;
- and
- receiving the HARQ-ACK based on the resource on the primary cell.
An apparatus of a user equipment for transmitting, a hybrid automatic repeat request acknowledgement (HARQ-ACK), the apparatus comprising:
- a controller configured to identify power of the HARQ-ACK based on transmission power control information in first downlink control information for a primary cell, and identify, for a time division duplexing (TDD) and a plurality of configured cells, a resource for transmission of the HARQ-ACK based on transmission power control information in second downlink control information with a downlink assignment index (DAI) value greater than 1;
- and
- a transmitter configured to transmit the HARQ-ACK based on the resource on the primary cell.
An apparatus for receiving, by a base station, a hybrid automatic repeat request acknowledgement (HARQ-ACK), the apparatus comprising:
- a transmitter configured to transmit transmission power control information in first downlink control information for a primary cell for power of the HARQ-ACK, and transmit, for a time division duplexing (TDD) and a plurality of configured cells, transmission power control information in second downlink control information with a downlink assignment index (DAI) value greater than 1 for a resource for transmission of the HARQ-ACK;
- and
- a receiver configured to receive the HARQ-ACK based on the resource on the primary cell.
