Abstract

MÉTODO PARA ESTABELECER UM SINAL DE REFERÊNCIA EM UM SISTEMA DE COMUNICAÇÃO DE RÁDIO E SISTEMA PARA O MESMO. A invenção refere-se a um método e um sistema para estabelecer um sinal de referência em um sistema de comunicação de rádio. O sistema de comunicação de rádio inclui uma célula servidora e uma célula vizinha, e um terminal móvel da célula servidora utiliza o mesmo recurso de frequência temporal de modo a receber um bloco de recursos de servidor da célula servidora e receber um bloco de recursos de interferência da célula vizinha. O método de acordo com a presente descrição inclui uma etapa de estabelecer um sinal de referência específico de usuário no bloco de recursos de interferência e uma etapa na qual uma perfuração é executada na mesma posição de frequência temporal que a posição de frequência temporal na qual o sinal de referência específico de usuário está estabelecido no bloco de recurso de interferência de modo a impedir que qualquer sinal seja transmitido na posição de frequência temporal perfurada. Quando o método e o sistema providos na presente descrição são utilizados e a potência de interferência entre as células é por meio disto medida, é possível reduzir efetivamente o excesso de retorno em uma formação de feixe coordenada.
