Method and device for transmission power control
The embodiments herein relate to a method in a base station for adjusting transmission power in a communications network. The base station determines a first number m; P of historical transmit power control, TPC, commands based on a signal power and an interference level. The base station determines a second number 2k; n+Q of current TPC commands based on the first number m; P of historical TPC commands, or based on the first number m; P of historical TPC commands and a third number n−K of signal power and interference level pairs. The base station transmits a sequence of TPC commands comprising the first number of historical TPC commands and the second number of current TPC commands to the user equipment to adjust the user equipment's transmission power.
