A method and apparatus for communication data signal blocking for a base radio control station (RCS) which wirelessly communicates with subscriber units (SUs) via a spread spectrum communication system is disclosed. A transmitter sends signals as a baseband combined signal over global and assigned channels to SUs. The SUs are set to initial power levels and the power levels are adjusted in advance of receiving signals on assigned channels. The power levels are combined to define an RCS transmitter power level, which is preferably a root mean square value of the baseband combined signal. The transmission power levels are adjusted in response to corresponding power control signals received from the SUs. Transmission of a new communication data signal on an assigned channel is blocked if a predetermined RCS transmitter power level limit is reached before commencing transmission of that signal.
