Patent ID: 7054301

Claim:
A method comprising: receiving, at a first time, an uplink signal from a first remote user terminal on a first carrier frequency at a first wireless communications base station together with ambient noise and interfering signals from at least one other remote user terminal on the first carrier frequency, the first carrier frequency being determined using a first hopping sequence used for communication with the first remote user terminal; determining a set of receive spatial processing parameters for the first remote user terminal and the first carrier frequency using the received uplink signal, the received noise and the received interfering signals; determining a second carrier frequency for use in communication with the first remote user terminal at a second time using the first hopping sequence; comparing the second carrier frequency to a predicted carrier frequency that will be used by the at least one other remote user terminal at the second time; and transmitting a downlink signal from the first base station to the first remote user terminal at the second time on the second carrier frequency using a set of transmit spatial processing parameters, the set of transmit spatial parameters being based on the set of receive spatial processing parameters if the second carrier frequency and the predicted carrier frequency are interfering carrier frequencies.
