BEAM FORMING METHOD, APPARATUS AND SYSTEM

摘要

The invention relates to a method of transmitting data in a communications system. The invention comprises: receiving from a user an uplink signal (2-4, 2-70) using multiple narrow antenna beams; measuring (2-36) beam-specific pilot signal powers from the uplink signal (2-70) 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 (2-70).
