20 Claims

13. A power control apparatus, comprising:

at least one processor; and

at least one non-transitory memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:

adjust, based on a first parameter, a first uplink transmit power for a terminal device comprising the apparatus to communicate with a source network device to determine a second uplink transmit power for the terminal device to communicate with a target network device, wherein a path loss between the terminal device and the source network device is different from a path loss between the terminal device and the target network device, and wherein the first parameter comprises at least one of a first compensation value of the first uplink transmit power or a second compensation value of a path loss factor corresponding to the first uplink transmit power; and

communicate with the target network device using the second uplink transmit power in a process of handing over the terminal device from the source network device to the target network device.
