HIGH SPEED DOWNLINK PACKET ACCESS COMMUNICATION IN A CELLULAR COMMUNICATION SYSTEM

摘要

A cellular communication system supports High Speed Downlink Packet Access (HSDPA) services. A first transceiver (201) transmits HSDPA downlink packet data in a first cell and a second transceiver (203) transmits HSDPA downlink packet data in a second cell. A cell overlap processor (205) can determine that a remote station (101) is in a cell overlap region between the first cell and the second cell. A macro-diversity controller (207) causes the first transceiver (201) to transmit first HSDPA data to the remote station (101) as a first signal in the first cell and the second transceiver (203) to transmit the first HSDPA data to the remote station (101) as a second signal in the second cell. The first and second signals are macro-diversity signals. The remote station (101) comprises a macro-diversity combiner (303) which receives the first downlink HSDPA packet data by combining the first signal and the second signal. The invention may allow improved support of HSDPA services in cell overlap areas.
