Method and apparatus for controlling uplink transmit power of UE, UE, and base station

A user equipment (UE), wherein the UE is connected to at least two base stations, the UE comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• determine subframe configuration information, wherein the subframe configuration information indicates base stations corresponding to all subframes in a radio frame;
• determine static power control parameters corresponding to all of the base stations;
• determine a transmit power control (TPC) adjustment value of a current subframe according to whether the current subframe and a previous subframe correspond to a same base station;
• and
• determine uplink transmit power of the current subframe according to a static power control parameter corresponding to a base station corresponding to the current subframe and further according to the TPC adjustment value of the current subframe.

A method for controlling uplink transmit power of user equipment (UE) connected to at least two base stations, the method comprising:

• sending subframe configuration information to the UE, wherein the subframe configuration information indicates base stations corresponding to all subframes in a radio frame;
• sending a static power control parameter of a base station to the UE, wherein the base station is one base station of the at least two base stations;
• and
• sending a transmit power control (TPC) adjustment value of a current subframe to the UE, so that the UE determines uplink transmit power of the current subframe according to the static power control parameter and the TPC adjustment value and further according to whether the current subframe and a previous subframe correspond to a same base station, wherein the current subframe is a subframe that is of subframes of the UE and that corresponds to the base station.

A base station, comprising:

• a transceiver, configured to:
• send subframe configuration information to UE, wherein the subframe configuration information indicates base stations corresponding to all subframes in a radio frame;
• send a static power control parameter of the base station to the UE;
• and
• send a transmit power control TPC adjustment value of a current subframe to the UE, so that the UE determines uplink transmit power of the current subframe according to the static power control parameter and the TPC adjustment value and further according to whether the current subframe and a previous subframe correspond to a same base station, wherein the current subframe is a subframe that is of subframes of the UE and that corresponds to the base station.
