BASE TRANSCEIVER STATION AND ASSOCIATED METHOD FOR COMMUNICATION BETWEEN BASE TRANSCEIVER STATION AND USER EQUIPMENTS

摘要

The invention relates to a base transceiver station (BTS) for communicating with a plurality of user equipments (UEl, UE2,UE3, UE4,UE5) divided in at least two groups, said base station comprises : - an antenna element arrangement generating at least two shifted static beams (Bi, Bo) with respective down tilts for reaching the user equipments (UEl, UE2, UE3,UE4,UE5) a processing unit (25) connected to said transceiver chains (9) and having means for performing at least two linear complex combinations of up-link digital signals - means for receiving said up-link signals and for selecting per user equipment the appropriate beam based on the quality of said up-link signals in the beam flows (Fi,F0).
