CELLULAR COMMUNICATION SYSTEM AND RE-USE PATTERN THEREFOR

摘要

A cellular communication system has a frequency bandwidth arranged into a plurality of frequency channels, and a plurality of neighbouring first (130) and second (132) sites each having sectors (a1-f1, a2-f2) containing at least one frequency channel. Corresponding sectors in each of the neighbouring first (130) and second sites (132) have consecutive frequency channels from the frequency bandwidth, thereby producing a two-site re-use pattern (134, 136). The cellular communication system may be adapted to support an underlay/overlay cell configuration in which neighbouring first (230) and second (232) sites each have six-sectors containing at least one frequency channel (b1-b12) of a two-site repeat pattern. The six sectors further each contain at least one frequency channel (t1-t6) of a one-site repeat pattern. Corresponding sectors in each of the neighbouring first (130) and second sites (132) have consecutive frequency channels in the two-site repeat pattern and identical channels in the one-side repeat pattern.
