ABSTRACT:
A single-cell wireless communication system is partitioned into n sectors, to which channels are allocated from two groups of non-adjacent channels. If the available channels are consecutively numbered from lowest to highest frequency, or vice versa, the groups are, respectively, the even-numbered channels and the odd-numbered channels. These two groups are each subdivided into n/2 sets, with the first set of each group including the lowest numbered channels of the group, the next set including the next lowest-numbered channels of the group, and so forth. The sets are then allocated to the sectors such that the first set of one of the groups is allocated to a first sector, the next set of the same group is allocated to a contiguous sector and so forth, with the last set of the second group allocated to the nth sector. The dividing points between the sets are selected such that any sector has at most a single channel that may experience adjacent-channel interference from a channel that is allocated from a contiguous sector. Preferably, a channel is selected for assignment to the mobile units such that the selected channel is within a greatest gap between the channels of the same set that are then in use. If the selected channel is the one channel that may experience adjacent-channel interference, another channel may be selected from the set.
