Abstract

1. Способ генерации блоков данных в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых: ! принимают первый блок данных от верхнего уровня; и ! генерируют второй блок данных, который включает в себя поле опроса, установленное в соответствии с состояниями буфера передачи и буфера повторной передачи и по меньшей мере части первого блока данных, ! причем в случае, когда в буфере передачи и буфере повторной передачи нет данных, подлежащих передаче к приемной стороне, поле опроса включает в себя значение, инструктирующее приемную сторону передать отчет о состоянии. ! 2. Способ по п.1, в котором блок данных, ожидающий подтверждения приема от приемной стороны, исключают при определении, имеются ли данные, подлежащие передаче к приемной стороне, в буфере повторной передачи. ! 3. Способ по п.1, в котором случай, когда в буфере повторной передачи нет данных, подлежащих передаче к приемной стороне, включает в себя случай, когда все блоки данных, для которых информация запроса повторной передачи была принята от приемной стороны, передают повторно. ! 4. Способ по п.1, в котором протокольный уровень является уровнем управления линией радиосвязи (RLC). ! 5. Способ передачи данных в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых: ! принимают отчет о состоянии от приемной стороны, причем отчет о состоянии запрашивает повторную передачу в отношении блока данных, хранимого в буфере повторной передачи; ! устанавливают поле опроса, включенное в блок данных, в соответ�

Claims (12)

1. Способ генерации блоков данных в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых:

причем в случае, когда в буфере передачи и буфере повторной передачи нет данных, подлежащих передаче к приемной стороне, поле опроса включает в себя значение, инструктирующее приемную сторону передать отчет о состоянии.
2. Способ по п.1, в котором блок данных, ожидающий подтверждения приема от приемной стороны, исключают при определении, имеются ли данные, подлежащие передаче к приемной стороне, в буфере повторной передачи.
3. Способ по п.1, в котором случай, когда в буфере повторной передачи нет данных, подлежащих передаче к приемной стороне, включает в себя случай, когда все блоки данных, для которых информация запроса повторной передачи была принята от приемной стороны, передают повторно.
4. Способ по п.1, в котором протокольный уровень является уровнем управления линией радиосвязи (RLC).
5. Способ передачи данных в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых:
принимают отчет о состоянии от приемной стороны, причем отчет о состоянии запрашивает повторную передачу в отношении блока данных, хранимого в буфере повторной передачи;

передают блок данных к приемной стороне,
причем в случае, когда в буфере передачи и буфере повторной передачи нет данных, подлежащих передаче к приемной стороне, после передачи блока данных, поле опроса включает в себя значение, инструктирующее приемную сторону передать отчет о состоянии.
6. Способ по п.5, в котором блок данных, ожидающий подтверждения приема от приемной стороны, исключают при определении, имеются ли данные, подлежащие передаче к приемной стороне, в буфере повторной передачи.
7. Способ выполнения процедуры опроса в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых:
проверяют состояния буфера передачи и буфера повторной передачи этого протокольного уровня; и
выполняют процедуру опроса для запрашивания приемной стороны передать отчет о состоянии, если как в буфере передачи, так и в буфере повторной передачи нет данных, подлежащих передаче к приемной стороне.
8. Способ по п.1, в котором выполнение процедуры опроса заключается в том, что:
устанавливают поле опроса блока данных, подлежащего передаче к приемной стороне, на некоторое конкретное значение; и
передают этот блок данных к приемной стороне.
9. Способ по п.8, в котором блок данных, ожидающий подтверждения приема от приемной стороны, исключают при определении, имеются ли данные, подлежащие передаче к приемной стороне, в буфере повторной передачи.
10. Способ выполнения процедуры опроса в протокольном уровне, выполняющем функцию повторной передачи данных в системе беспроводной связи, причем способ содержит этапы, на которых:
генерируют блок данных, включающий в себя часть заголовка и часть поля данных;
проверяют, превышает ли сумма размера данных, включенных по меньшей мере в один блок данных, переданных к приемной стороне, и размера данных, включенных в сгенерированный блок данных, заданный порог; и
выполняют процедуру опроса, если сумма размеров этих данных превышает заданный порог.
11. Способ по п.10, в котором размер данных, включенных в части полей данных по меньшей мере одного блока данных и сгенерированного блока данных, рассматривают только при вычислении суммы размеров данных.
12. Способ по п.10, в котором процедуру опроса выполняют посредством установки поля опроса, включенного в заголовок сгенерированного блока данных, на некоторое конкретное значение.
