<p>The area of coverage of a cellular wireless communications network is divided into sectors, each sector having a respective predetermined set of frequencies selected for use in the sector. Radio frequency signals are transmitted from an antenna arrangement (8a, 8b, 8c) of a base station of the cellular wireless communications network in a first beam 10a to a first sector and the same radio frequency signals are transmitted simultaneously in a second beam 12a to a second sector, the first and second beams having substantially opposite directions in azimuth, and the first sector having the same predetermined set of frequencies (f1) as the second sector. The radio frequency signals comprise at least a first signal for communication with a first user terminal in the first sector and at least a second signal for communication with a second user terminal in the second sector, the first signal being different from the second signal.</p> |
