Abstract

Описаны методы передачи данных с разнесением циклических задержек и смещением пилотного сигнала. Для разнесения циклических задержек генерируются OFDM-символы, которые имеют разные длительности циклических задержек. Длительности циклических задержек для OFDM-символов могут выбираться изменяемыми во времени относительно длительностей циклических задержек для OFDM-символов, переданных соседней базовой станцией. Пилот-сигнал FDM генерируется и мультиплексируется во множественное число наборов поддиапазонов в разные периоды символов. Сигналы для другого метода радиосвязи (например, W-CDMA) могут генерироваться для данных, которые должны передаваться с использованием этого метода радиосвязи. OFDM -символы мультиплексируются во временные интервалы, которые используются для OFDM, и сигналы, для другого метода радиосвязи мультиплексируются во временные интервалы, которые используются для этого метода радиосвязи. Один или множественное число модулируемых сигналов могут генерироваться на основе мультиплексированных OFDM -символов и сигналов. Каждый модулируемый сигнал передается соответствующей антенной.
