Abstract:
The invention relates to a method of transmitting data in a communications system. The invention comprises: receiving from a user an uplink signal using multiple narrow antenna beams; measuring beam-specific pilot signal powers from the uplink signal for all the beams; and using the measured pilot signal powers to determine which one or ones of the downlink beams is to be used for a downlink signal for the user.
