Abstract

Способ связи для пользовательского терминала в системе радиосвязи, в которой каждый из пользовательских терминалов выполняет мультиплексирование сигнала данных и пилот-сигнала и передает мультиплексированный сигнал в базовую станцию, используя разные частоты полосы передачи данных, которые назначаются базовой станцией, причем способ связи содержит этапы, на которых:принимают информацию ресурсов восходящей линии связи от базовой станции; игенерируют последовательность Задоффа-Чу в качестве пилот-сигнала на основании информации ресурсов восходящей линии связи;выполняют отображение последовательности, генерируемой циклическим копированием последовательности Задоффа-Чу; ипередают отображаемый пилот-сигнал в базовую станцию.
