摘要： Measured are received power of a first signal received from a first entity, and received power of a second signal received from a second entity. A gain factor (or a matrix of gain factors if multiple antennas are used) is determined using the measured received powers of the first signal and of the second signal. If transmit power from the apparatus to the second entity is considered as the benchmark, the second signal is forwarded from the apparatus to the first entity using a second signal transmit power that is determined using the gain factor. Or, if transmit power from the apparatus to the first entity is considered as the benchmark, the first signal is forwarded from the apparatus to the second entity using a first signal transmit power that is determined using the gain factor. Method, apparatus, and memory storing computer program are detailed.

摘要： A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when Eb/No measurements for served mobiles do not meet target Eb/No levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target Eb/No levels in a centralized manner based on an overall system state so that only a limited number of target Eb/No levels are allowed to increase when frame erasures occur. By preventing a percentage of target Eb/No level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.
