Abstract

COMPARTILHAMENTO DE RECURSO EM OPERAÇÕES DE RETRANSMISSÃO EM SISTEMAS DE COMUNICAÇÃO SEM FIO. Um terminal de retransmissão de comunicação sem fio, que inclui um controlador acoplado ao transceptor, onde o controlador é configurado para fazer com que o transceptor transmita uma primeira porção de um primeiro subquadro durante uma primeira região de tampo - frequência para um dispositivo receba a partir de uma estação base uma porção de um segundo subquadro durante uma segunda região de tempo - frequência, onde a primeira e segunda regiões de tempo - frequência são de não superposição. O controlador também é configurado para a detecção de uma região de controle na porção do segundo subquadro recebida pela tentativa de decodificar uma informação em uma possível região de controle do segundo subquadro tendo pelo menos uma de várias localizações de começo possíveis que são conhecidas a priori pelo terminal.
