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.

A method for configuring a transmission of data over a communication channel to or from a wireless communication unit within a femto cell comprises, at an access point for the femto cell, receiving an indication of at least one communication channel condition (CQI) from the wireless communication unit and configuring a capacity allocation (transport block size) for the transmission of data to or from the wireless communication unit based at least partly on the received indication.

Channel assignment in enhanced fixed-plan mobile communications systems

In a multi-reuse level cellular communications system, a channel is assigned for use by a mobile unit by first determining whether the mobile unit is a non-enhanced mobile unit or an enhanced mobile unit. Then a determination is made as to the type of communication service being requested. A minimum link quality required by the mobile unit can then be established based on factors that include the mobile unit type and the type of communication service being requested. A base station that has the necessary receiver detection capabilities and transceiver processing capabilities is then selected, and a channel, corresponding to a highest reuse plan, available to the base station is assigned to the call.

Adaptive modulation and coding method

An adaptive modulation and coding method comprises selecting (S7) one of a plurality of different available modulation and coding levels to apply to a signal transmitted from a transmitter to a receiver. The selection is based on a comparison between a signal transmission quality («or/Ioc) and one or more threshold values. The or each threshold value is adjusted (S5, S6) when the signal transmission quality is within a predetermined range of that threshold value, and is maintained unchanged (S3) when the signal transmission quality is outside that range. By maintaining the threshold value unchanged when the signal transmission quality is outside the range of that value the adjustments to the threshold value(s) are limited, whilst still enabling the threshold value(s) to take account of prevailing signal transmission conditions. This leads to improved throughput performance, especially under path conditions involving a single dominant path.

Techniques directed to attributing information regarding communications with a modulation scheme to a different modulation scheme are described. In one example, a successful communication for a higher data rate modulation scheme may be attributed to a lower data rate modulation scheme.
