Embodiment Construction

[0058] figure 1 An example of a UMTS cellular communication system according to some embodiments of the present invention is shown.

[0059] In a cellular communication system, a geographic area is divided into cells, each of which is served by a base station. The base stations are connected to each other by a fixed network that can communicate data between the base stations. A remote station, such as a user equipment (UE) or mobile station, is served via a wireless communication link by the base station of the cell within which the remote station is located.

[0060] exist figure 1 In the example, the first remote station 101 and the second remote station 103 are in a first cell supported by the first base station 105 .

[0061] The first base station 105 is coupled to a first RNC 107 which is further coupled to a second base station 109 . The RNC performs various control functions related to the air interface, including radio resource management and data routing to and f...

Abstract

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.

Description

technical field [0001] The present invention relates to high speed downlink packet access communications in cellular communication systems, and more particularly to the support of remote stations in areas where cells overlap. Background technique [0002] Currently, the most common cellular communication system is the second generation communication system known as the Global System for Mobile Communications (GSM). A further description of the GSM TDMA communication system can be found in "The GSM System for Mobile Communication" by Michel Mouly and Marie Bernadette, Bay Foreign Language Books, ISBN 29507 19007. [0003] Recently, third-generation systems have been introduced in many regions to further enhance the communication services provided to mobile users. One such system is the Universal Mobile Telecommunications System (UMTS) currently being deployed. More descriptions of the Wideband CDMA (WCDMA) mode in CDMA, especially UMTS, can be found in "WCDMA for UMTS" by H...
