Abstract

1//1 resumo “métodos e aparelhos para manipular sinais de referência em uma rede celular” a descrição refere-se a métodos e aparelhos para possibilitar que um sinal de referência de demodulação configurado seja transmitido a partir de um equipamento de usuário, eu (202) quando servido por uma estação base (200) em uma rede celular. a estação base envia (2:3) ao menos um parâmetro de configuração ao eu, o que indica uma sequência base específica do eu e/ou um padrão de salto de deslocamento cíclico específico do eu (2:2) ao eu. o eu usa então parâmetros de configuração para gerar (2:4) e transmitir (2:5) o sinal de referência de demodulação base- ado na sequência base específica do eu e no padrão de salto de deslocamento cíclico específico do eu. desse modo, a ortogonalidade pode ser alcançada entre o sinal de referência de demodulação transmitido e quaisquer sinais de referência de demodulação transmitidos por outros eus, usando as sequências base específicas do eu separadas e/ou padrões de salto de deslocamento cíclico específicos do eu.
