Power adjustment method and apparatus

A communications apparatus, comprising:

• a receiver, configured to receive a medium access control control element (MAC CE), wherein the MAC CE is configured to update a pathloss estimation reference signal;
• and
• a processor, configured to determine a pathloss estimation value based on the pathloss estimation reference signal, wherein an application time of the pathloss estimation value is no later than n+X+T, where n is a time for sending feedback information indicating whether the MAC CE is correctly received, X is a fixed duration, T is a variable duration, and X and T are finite non-zero values, and
• determine transmit power of an uplink signal based on the pathloss estimation value.

A non-transitory computer-readable storage medium, storing a computer-executable program, which when executed by a processor, causes the processor to implement operations comprising:

• receiving a medium access control control element (MAC CE), wherein the MAC CE is configured to update a pathloss estimation reference signal;
• determining a pathloss estimation value based on the pathloss estimation reference signal, wherein an application time of the pathloss estimation value is no later than n+X+T, where n is a time for sending feedback information indicating whether the MAC CE is correctly received, X is a fixed duration, T is a variable duration, and X and T are finite non-zero values;
• and
• determining transmit power of an uplink signal based on the pathloss estimation value.
