Transmission Power Control of User Equipment Communicating with Low Power Base Station and High Power Base Station

摘要

There is provided improved interference control of uplink transmissions, when user equipment is communicating with at least two base stations in a communications network. A threshold is defined for a difference of the determined allowed transmission power to an allowed transmission power for the user equipment to a second base station of the at least two base stations. It is determined whether the determined allowed transmission power to the first base station meets the defined threshold. Transmission rate of relative power control commands from at least one of the base stations is changed, when the threshold is met.

1. A method comprising:
determining an allowed transmission power for user equipment to a first base station of at least two base stations communicating with the user equipment in a communications network; defining a threshold for a difference of the determined allowed transmission power to an allowed transmission power for the user equipment to a second base station of the at least two base stations; determining whether the determined allowed transmission power to the first base station meets the defined threshold; and causing to change a transmission rate of relative power control commands from at least one base station of the base stations, when the threshold is met.
