ABSTRACT:
In a cellular communication system, an array of sector antennas is provided at each cell site for respectively covering sectors of the service area of the cell site. At each cell site, undesired signals of different channels are received by each antenna, and their magnitudes are determined. One of the signals is selected from each set of signals from the antennas depending on their magnitudes to produce channel signals respectively for the different channels. A list of candidate channels is determined corresponding to those of the channel signals whose qualities are higher than a threshold. One of the candidate channels is selected from the list depending on the magnitudes of those channel signals whose qualities are higher than the threshold. The selected candidate channel is assigned to a mobile station if the selected channel has acceptable quality. Otherwise, it is discarded from the list and the attempt is repeated to select a further candidate channel.
