  • Patent number: 8280427
    Abstract: 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.
