Abstract:
1. A user equipment (UE) in a communication system, comprising: a device that recovers control symbols intended for the UE, wherein the control symbols include transmit power control (TPC) commands directed to the UE from at least two transmitting nodes, one of the transmitting nodes being a serving node for a predetermined communication service; a TPC command filter configured to generate a ratio signal from TPC commands directed to the UE from the serving node during a plurality of time slots; and a TPC combiner that is responsive to the ratio signal and is configured to receive TPC commands from the device and, based on the received commands and the ratio signal, to generate a TPC control signal that is used for controlling power transmitted by the UE; wherein, if the ratio signal crosses a first threshold, the TPC control signal is based on only TPC commands directed to the UE from the serving node; and if the ratio signal does not cross the first threshold, the TPC control signal is based on a combination of the TPC commands directed to the UE from the at least two transmitting nodes.
