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

Номер: RU2193291C2

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.

The invention seeks to provide a more concise frame structure by sending configuration data with a repetition length rather than sending configuration data in every frame as is typical. In transmission of data in a wireless communication system, the data may be transmitted in frames, each of which comprises a data section carrying data streams, and a preamble section carrying configuration data items comprising configuration data for use in receiving one or more corresponding data streams. In what is described herein, different repetition lengths are set for different respective types of configuration item, each repetition length defining a number of frames that sequentially follow within a frame structure before the respective type of data item is repeated. Data is transmitted in a sequence of frames such that the configuration data items are transmitted according to the respective repetition lengths. Thus, a relatively short repetition length may be set for configuration data items that ...

Alternatively the cyclic redundancy code and parity field are replaced by a shortened Reed Solomon code. A method of multiplexing time critical data is also described which comprises determining what data is available for multiplexing to a data unit at a given time, and allocating data to a data field of the data unit appropriately, wherein during allocation of the data to the data field priority is given to time critical data by not allocating non time critical data to the data field of the data unit unless all of the available time critical data has been allocated to the data unit.

There exists a need to reduce re-transmission delays in real time feeds (such as video) by sending the packet with sufficient repair/recovery information inside the packet container so the relaying stations and/or the receiving devices can fix errors in transmission by perusing the contents of the packet and the repair information, and modify the packet and then relay it. By providing the relaying station the ability to fix the error, retransmission of the packet is avoided along each relay station along the network path from source to destination and also by receiving devices that would otherwise request a re-transmission. This application teaches a method so real time streams (e.g. video) may be more efficiently transported over a CSMA based network.

A polar code may be initially divided into multiple polar component codes where the features of these component codes, such as the number of component codes and the size of the component codes, are determined based on parameters such as the number of available timing units within a transmission interval, interleaving depth, and decoder capability. For each selected component code, the order of code bit generation and their indexes may be determined. The determined indexes may be assigned into different, unique groups according to the order of code bit generation. An interleaving operation may be configured and then executed according to the determined index grouping. In the transmission phase, the code bits may be transmitted based on the identified order of the bit generation in the component polar codes, such as the determined index grouping.
