Controlling transmission power levels in air interface channel

Transmission power levels in the other channels of an air interface, e.g. in a CDMA wireless communication system, are reduced if the inteference from those other channels in one channel which is required to send a signal requiring a high quality of service (QoS), is excessive for the needed QoS. Also, if the power in the other channels cannot be reduced, alternatively, the intefering sources may have their transmissions suppressed or delayed. If this step is not appropriate the high QoS signal itself may be delayed. The process is used in situations where base stations may be collocated, e.g. in an indoor WLAN, where access points and mobile users may be closely adjacent.
