COLLABORATIVE BEAM FORMING OF BASE TRANSCEIVER STATIONS FOR REDUCING INTERFERENCE IN A WIRELESS MULTI-CELL NETWORK

摘要

A method of signal transmission and reception for a cellular wireless network includes steps of detecting signal strength of signals transmitted or received between a mobile station and a plurality of base transceiver stations; selecting a plurality of candidate serving base transceiver stations based on the detected signal strength; selecting a first group of serving base transceiver stations from the candidate serving base transceiver stations; and sending signals between the mobile station and the first group of serving base transceiver stations using beam forming technology to reduce interference received by the mobile station.
