Abstract

Способы и устройство для обработки и генерации широковещательных сообщений, определенных поддиапазоном и OFDM символами кадров, в которых принимаются сигналы. Генерируются служебные сообщения, которые указывают ресурсы, которые используются широковещательными сообщениями в системе беспроводной связи. Сигналы принимаются в беспроводной системе, и широковещательные сообщения определяются из сигналов, которые указываются поддиапазоном и OFDM символами кадров ультракадра, в котором принимаются сигналы.
