Abstract:
1. A method of operating a base station of a cellular radio system to serve a coverage area, the method comprising: moving a downlink beam to one or more angular positions in a sector of a cell in the coverage area, wherein the downlink beam comprises at least two directional beams of similar beam widths, and the downlink beam is coupled to a base station of a cellular radio system in a coverage area; associating the angular positions of the two directional beams with a time interval of a plurality of successive time intervals such that the two directional beams move in a cyclic repeated pattern and a portion of the two beams overlap; and during a first time interval of the successive time intervals, transmitting one or more signals in one of the directional beams to a first user terminal located in a first beam of the directional beams; changing the angular position during a second time interval of the successive time intervals such that a second user terminal is located near the center of the first beam; and during a second time interval, transmitting one or more signals in the first beam to the second user terminal.
