Abstract:
1. A terminal in a communication system, comprising: a device that recovers control symbols intended for the terminal, wherein the control symbols include transmit power control (TPC) commands directed to the terminal from at least one transmitting node to which the terminal is connected and at least one node to which the terminal would be simultaneously connected; a TPC combiner adapted to receive TPC commands from the device and, based on the commands, to generate a combined TPC command that is used for increasing or decreasing a transmit power of the terminal; and an uplink synchronization detector adapted to recognize a TPC command pattern expected to be directed to the terminal from the at least one node to which the terminal would be connected until synchronization is achieved on an uplink channel between the terminal and the at least one node to which the terminal would be connected; wherein the combined TPC command is not based on the TPC commands from the at least one node to which the terminal would be connected if the expected TPC command pattern is recognized in those TPC commands.
