Abstract
The present invention relates to 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 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 radio transmitter has been established at a particular point in time; selecting (303), based on the direction-of-propagation information, active directions for the communication of common channels from the radio transceiver; and adjusting (305) 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.

43. A user equipment for communication within a mobile radio communications system comprising at least one stationary radio transmitter, wherein the user equipment is configured to:
-
receive a first radio signal transmitted from a stationary radio transmitter; identify a direction identity included in the first radio signal, the direction identity identifying a direction into which the first radio signal was transmitted at the stationary radio transmitter; and send a second radio signal to the stationary radio transmitter, wherein the second radio signal is indicative of said direction identity.
