Abstract: A beam having the best performance for the present downlink transmits the signal carrying information. In another beam transmitted, in a corresponding manner having the best performance in regard to the next mobile station to be communicated in a next time slot, a signal is created which has a low cross correlation relative to the present signal carrying information. The average power in the direction to the next mobile station to be communicated in the next TDMA time slot will be given by the sum of the average power of the two signals after amplification by the respective antenna pattern. This takes place because the cross correlation between the signals is low due to which fact the summed signal will show a power addition but not a coherent addition. This is feasible as the summed signal is not be decoded by the next mobile station, but used entirely as a measurement of power.

Abstract: When a request for reception of radio signals is delivered by wireless communication section 3, subordinate processing portion 12 fetches programs necessary for reception of radio data from external memory 2 and stores them into command cache memory 13. At this instant, to prevent data stored in command cache memory 13 from being altered by other interrupt requests, the system instructs interrupt controller 16 to mask all interrupt requests except urgent ones. Through this arrangement it is possible to reduce noise during execution of a specific processing, particularly during reception of data.

Abstract: The invention provides a system and method for controlling transmission power of a mobile unit in a wireless communication system which minimizes transmission power overshoot caused by counteracting the effects of deep fading. Sets of power control bits are transmitted from the base station to the mobile unit using &pgr;/4 DQPSK modulation. A first set of the bits indicates to the mobile unit a request to increase the mobile units transmission power by a predetermined amount. A second set of the bits indicates to the mobile unit that the mobile unit should increase its transmission power by an amount which is greater than the predetermined amount. A third set of the bits indicates to the mobile unit a request to decrease the mobile units transmission power by the predetermined amount. A fourth set of the bits indicates to the mobile unit that the mobile unit should decrease its transmission power by the amount which is greater than the predetermined amount.
