Abstract:
1. A method of controlling a mobile communication device comprising: transmitting by a mobile communication device a first diversity signal using a first value of a phase parameter; receiving from a non-serving base station a phase feedback signal based on the first diversity signal; receiving from the serving base station a plurality of serving power feedback signals based on the diversity signal; receiving from the non-serving base station a plurality of non-serving power feedback signals based on the diversity signal; comparing said plurality of non-serving power feedback signals to said plurality of serving power feedback signals; determining based on said comparison whether or not to perform said step of calculating the modified value modifying the first value in the direction opposite to the direction indicated by said phase feedback signal; calculating a modified value of the phase parameter, said modified value modifying the first value of the phase parameter in a direction opposite to a direction indicated by said phase feedback signal; and transmitting a modified diversity signal using the modified value of the phase parameter.
