Abstract:
A system and method are provided for boosting power for a communications link between a base station and a user device, or user equipment, over a communications link channel in a cellular communications network. In one embodiment, the base station determines whether a communications link for a user device located within a sector of a cell served by the base station needs a power boost. If a power boost is needed, the base station provides a power boost for the communications link for the user device and, for each of one or more neighboring sectors that neighbor the sector in which the user device is located, coordinates the power boost in both frequency and time with a power backoff for a downlink to another user device located in a cell center area of the neighboring sector.
