Abstract

métodos e disposições para transmitir e decodificar sinais de referência. em algumas modalidades, proporciona-se um método em um nó de rede de rádio para transmitir um sinal de referência através de uma porta de antena, em que o sinal de referência é transmitido em um grupo de multiplexação por divisão de código, cdm. o grupo cdm compreende pelo menos dois subgrupos cdm, sendo que cada subgrupo cdm é transmitido em uma subportadora diferente. cada subgrupo cdm compreende elementos de recurso. em uma primeira etapa, o nó de rede de rádio transmite o sinal de referência através de um primeiro subgrupo cdm utilizando um código de cobertura ortogonal. o primeiro subgrupo cdm compreende elementos de recurso em uma primeira partição de tempo e em uma partição de tempo subsequente. em uma etapa adicional, o nó de rede de rádio transmite o sinal de referência através de um segundo subgrupo cdm utilizando uma permutação do código de cobertura ortogonal. o segundo subgrupo cdm compreende elementos de recurso na primeira partição de tempo e na segunda partição de tempo. a permutação do código de cobertura ortogonal é selecionada de tal modo para permitir a decodificação do sinal de referência no domínio de frequência, ao aplicar o código de cobertura ortogonal apenas a elementos de recurso no grupo cdm que estão compreendidos na primeira partição de tempo.
