СПОСОБ ОБЕСПЕЧЕНИЯ ВЫСОКОСКОРОСТНОЙ ПЕРЕДАЧИ ДАННЫХ В ОБОРУДОВАНИИ СОТОВОЙ СВЯЗИ И УСТРОЙСТВО ДЛЯ ЕГО ОСУЩЕСТВЛЕНИЯ

Изобретение относится к системам связи, в частности к высокоскоростной передаче данных в оборудовании беспроводной сотовой связи. Технический результат - повышение скорости передачи данных за счет выбора скорости кодирования передаваемых сигналов при поддержании скорости передачи постоянной и за счет выбора формата модуляции передаваемого сигнала, который непосредственно измеряет скорость передачи на абонентскую станцию. Соседним ячейкам сотовой системы запрещено передавать данные одновременно. Поскольку главным источником помех является шум от передачи соседних ячеек, то скорость передачи базовых станций с ограниченной мощностью можно резко увеличить, если исключить шум от соседних ячеек. Передачи на каждую абонентскую станцию выполняются с фиксированным уровнем мощности передачи. Однако скорость передачи данных передаваемых сигналов изменяется от одной абонентский станции к другой в зависимости от различий в потерях на трассе. 4 с. и 20 з.п.ф-лы, 7 ил.

SUB-BAND POSITION MODULATION TECHNIQUES FOR WIRELESS COMMUNICATION

Aspects of the disclosure relate to efficiently exchanging data in power-limited wideband communications. A base station and a UE transmit some or all data using sub-band position modulation (SBPM), in which a select subset of frequency sub-bands carry the data transmission. At a given interval of the streamed data portion, a new subset of the sub-bands may be selected as the active sub-bands, thus modulating the active sub-band positions during the data transmission. A receiver monitors for the data transmission signal and detects the sub-bands on/off state in order to receive the data within the active sub-bands. This is “blind” detection—the entities exchange no control information indicating which sub-bands a given transmission uses. Further, SBPM includes pattern recognition by both devices in order to convey additional information each interval by selecting the positions of the active sub-bands to match the pattern associated with the information to be conveyed. 1.
