Abstract

<B>DISPOSITIVO PARA DIVERSIDADE DE TRANSMISSãO COMUTADA POR TEMPO (TSTD) E SEU MéTODO DE CONTROLE EM SISTEMA DE COMUNICAçãO MóVEL<D> é fornecido um método de controle de diversidade de transmissão em um sistema de comunicação móvel que inclui uma estação base que transmite dados de canal comum de encaminhamento e dados de canal dedicado, através de pelo menos duas antenas com diversidade de transmissão. A estação base envia uma mensagem indicando um modo de transmissão TSTD/não-TSTD através de uma antena para uma pluralidade de estações móveis na área de cobertura da estação base. Depois, cada estação móvel analisa a mensagem recebida da estação base e fixa seu modo de recepção para um modo TSTD/não-TSTD, de acordo com o modo de transmissão.<B> DEVICE FOR TIME-SWITCHED TRANSMISSION DIVERSITY (TSTD) AND ITS CONTROL METHOD IN A MOBILE COMMUNICATION SYSTEM <D> A method of transmitting diversity control is provided on a mobile communication system that includes a base station that transmits common routing channel data and dedicated channel data, through at least two antennas with transmission diversity. The base station sends a message indicating a TSTD / non-TSTD transmission mode through an antenna to a plurality of mobile stations in the coverage area of the base station. Then, each mobile station analyzes the message received from the base station and sets its reception mode to a TSTD / non-TSTD mode, according to the transmission mode.
