Abstract

APARELHOS E MÉTODOS PARA AQUISIÇÃO DE DADOS DE QUALIDADE DE CANAL DE MÚLTIPLAS ANTENAS EM UMA REDE DE SERVIÇO DE DIFUSÃO/MULTIDIFUSÃO UTILIZANDO UM SÍMBOLO DE MULTIDIFUSÃO. Vários métodos e aparelhos fornecem aquisição de dados de canal de difusão ponto a ponto, como informações de antena, a partir de subquadros de Serviço de Difusão/Multidufusão de Multimídia (MBMS). Um método de operar uma entidade de infraestrutura de rede de comunicação sem fio é revelado que compreende definir um subquadro de Rede de Frequência Única de Difusão/Multidifusão (MBSFN) (400) que compreende um símbolo de difusão ponto a ponto (401) compreendendo pelo menos um primeiro símbolo de referência de antena; definir uma segunda posição de símbolo (403) no subquadro (400) para conter pelo menos um segundo símbolo de referência de antena de difusão ponto a ponto; e transmitir o subquadro (400) onde o símbolo de difusão ponto a ponto (401) compreende pelo menos um primeiro símbolo de referência de antena e onde o símbolo de multidifusão (403) compreende pelo menos o segundo símbolo de referência de antena de difusão ponto a ponto.
