Abstract

métodos e aparelhos para indicar e para detectar parâmetros de temporização e uma identidade de um grupo de célula particular parâmetros de temporização e uma identidade de um particular dentre um número de grupos de célula são indicados em um sinal transmitido em um sistema de comunicação celular possuindo um quadro de rádio em uma camada física, o quadro de rádio compreendendo um número de intervalo de tempo. em um intervalo de tempo conhecido dos intervalos de tempo ' um sinal de sincronização s1 é transmitido, o qual compreende um par de seqüências (i) arranjadas em uma primeira ordenação. em um outro intervalo de tempo dos intervalos de tempo conhecido, um sinal de sincronização s2 é transmitido, o qual compreende o par de seqüências (ii) arranjadas em uma segunda ordenação. o par de seqüências selecionadas é univocamente identificado com o grupo de célula particular, e a primeira ordenação das seqüências é usada somente para transmissão no conhecido dos intervalos de tempo, e a segunda ordenação de seqüências é usada somente para transmissão no citado outro dos intervalos de tempo conhecido.
