Patent ID: 8494588

Claim:
A method of improving the performance of a mobile radio communications system comprising at least one stationary radio transmitter for communicating with user equipments in the communications system, wherein the stationary radio transmitter is connected to an antenna system for which the antenna pattern can be varied, the method comprising: receiving direction-of-propagation information relating to a plurality of user equipment transmission samples, wherein a user equipment transmission sample includes information relating to at least one direction of propagation by which successful communication between a user equipment and the stationary radio transmitter has been established at a particular point in time; selecting, based on the direction-of-propagation information, active directions for the communication of common channels from the stationary radio transmitter; and adjusting the antenna pattern used for communication of common channels in accordance with the selected active directions in a manner so that the gain of at least one direction which has not been selected as active is lower than the gain of the selected active directions.
