セルラ単一周波数ネットワークのための送信空間ダイバーシチ

Japanese Patent JP2008547267

A

A method of transmitting data from a plurality of sectors in a cellular communication system is described, the method comprising: assigning at least one transmit antenna of each sector of the plurality of sectors into a first transmit antenna set or a second transmit antenna set, each antenna set of the first and second transmit antenna sets comprising at least one transmit antenna; arranging the data into a first data stream and a second data stream; hierarchically modulating a carrier of a given frequency to obtain a first signal having a first base layer and a first enhancement layer; hierarchically modulating the carrier to obtain a second signal having a second base layer and a second enhancement layer; transmitting the first signal through each transmit antenna in the first transmit antenna set; and transmitting the second signal through each antenna in the second transmit antenna set; wherein the steps of hierarchically modulating are performed so that the first base layer carries information of the first data stream, the first enhancement layer carries information of the second data stream, the second dbase layer carries information of the second data stream, and the second enhancement layer carries information of the first data stream. A corresponding method of receiving is also described.
