Method and device for transmitting uplink transmission power control information

摘要

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.

1. A method for transmitting uplink transmission power control information, comprising:
in a scenario of a carrier aggregation where multiple uplink component carriers and multiple downlink component carriers are aggregated, transmitting by one or more integrated circuits of a base station uplink transmission power control information of all the multiple uplink component carriers allocated to a user equipment (UE) on one specific downlink component carrier of the multiple downlink component carriers to the UE; wherein the uplink transmission power control information is carried in a downlink control information format 3/3A, said one specific downlink component carrier corresponds to an uplink component carrier of the UE, said uplink component carrier transmits uplink control information of the UE; when the uplink transmission power control information is transmitted by adopting the downlink control information format 3, in an information domain of the downlink control information format 3, the uplink transmission power control information of each uplink component carrier is carried by using 2 bits, and an initial position of each uplink transmission power control information is marked layer in a high layer signaling and the initial position is an even number; when the uplink transmission power control information is transmitted by adopting the downlink control information format 3A, in an information domain of the downlink control information format 3A, the uplink transmission power control information of each uplink component carrier is carried b using 1 bit, and an initial position of each uplink transmission power control information is marked in a high layer signaling.
