Abstract
A method of directional radio communication between a first station and a second station, the method comprising the steps of defining at the first station a plurality of beam directions available for transmitting successive signals from the first station, selecting at said first station at least one of said directions for transmission of a signal from said first station to said second station, wherein the selection of the at least one direction for transmission is such that successive signals or groups of signals are transmitted in substantially different directions and such that on average each beam direction available to said first station is used substantially equally.

A method of directional radio communication between a first station and a second station, the method comprising the steps of:
- determining at the first station a plurality of beam directions which are feasible for use in transmitting a signal from said first station to said second station using a signal received from said second station;
- selecting at said first station, from the plurality of beam directions, a direction for transmission of a signal from said first station to said second station, wherein the selection of the direction for transmission is such that successive signals or groups of signals are transmitted in substantially different directions and such that on average each of said plurality of beam directions is used a substantially equal number of times.
Apparatus for directional radio communication between a first station and a second station, the apparatus comprising:
- a circuit that determines a plurality of beam directions which are feasible for use in transmitting a signal from said first station to said second station using a signal received from said second station;
- and
- a circuit that selects at said first station, from the plurality of beam directions, a direction for transmission of a signal from said first station to said second station, wherein the selection of the direction for transmission is controlled such that successive signals or groups of signals are transmitted in substantially different directions and such that on average each of said plurality of directions is used a substantially equal number of times.
