Abstract
A method and an apparatus for transmitting uplink transmission power control information are disclosed. The method includes: transmitting uplink transmission power control information of all uplink component carriers allocated to a user equipment (UE) to the UE by one downlink component carrier. By adopting the above technical scheme, it is implemented that the uplink transmission power control information is transmitted in a carrier aggregation system.
Claims19
A method for transmitting uplink transmission power control information, comprising:
- transmitting uplink transmission power control information in a downlink control information format 3/3A of all uplink component carriers allocated to a user equipment (UE) to the UE by one downlink component carrier.
The method according to any one of claims 4-3, wherein,
- the step of transmitting the uplink transmission power control information in the downlink control information format 3/3A of all the uplink component carriers allocated to the UE to the UE by one downlink component carrier comprises:
- carrying the uplink transmission power control information in the downlink control information format 3 of all the uplink component carriers in a consecutive domain of a-the downlink control information format 3, and notifying, by a base station, initial position information of the uplink power control information in the downlink control information format 3 to the UE by a signaling;
- or
- carrying the uplink transmission power control information in the downlink control information format 3A of all the uplink component carriers in a consecutive domain of the downlink control information format 3A, and notifying, by a base station, initial position information of the uplink power control information in the downlink control information format 3A to the UE by a signaling.
An apparatus for transmitting uplink transmission power control information, which is configured to:
- transmit uplink transmission power control information in a downlink control information format 3/3A of all uplink component carriers allocated to a user equipment (UE) to the UE by one downlink component carrier.
