Abstract

"APARELHO DE COMUNICAçãO DE RáDIO E MéTODO DE TRANSMISSãO DE SìMBOLO PILOTO". A presente invenção refere-se a um aparelho de comunicação de rádio que permite que a influência das informações de retorno sobre a capacidade do canal seja mantida no mínimo sem reduzir a eficiência de transmissão de informações pela transmissão do símbolo piloto. No aparelho, uma seção de medição de dispersão de retardo (272) gera um perfil de retardo utilizando o sinal recebido, e mede a dispersão de retardo indicativa da dispersão de versões retardadas. Uma seção de estimativa de velocidade de movimento (274) estima a velocidade de movimento de um aparelho de estação móvel que transmite um símbolo piloto com base na variação na potência de recepção do símbolo piloto. Uma seção de medição de interferência de outras células (276) mede a interferência de outras células causada por sinais transmitidos nas células exceto a célula à qual o aparelho pertence. Correspondendo à dispersão de retardo, à velocidade de movimento e à interferência de outras células, uma seção de geração de informações padrão piloto (278) seleciona um padrão piloto de modo que a colocação do símbolo piloto seja ótima em um quadro, e gere as informações padrão piloto.
