摘要： A method and an apparatus for transmitting error-tolerant data is disclosed employing the ARQ technique, wherein the retransmission of erroneous data is performed up to the point where the remaining amount of errors is acceptable (for instance because the erorrs will not be perceived by the recipient of the information, which can be a person or a higher level protocol with additional error correction capabilities). The number of data blocks (RLC) detected as erroneous is employed to define a reliability measure (RM) and a request for retransmission of the erroneous data blocks is performed until a desired reliability threshold (RT) is reached. An additional threshold with a higher value than the first one can be employed to request for optional retransmission when the reliability measure (RM) is between the first and the second threshold. The retransmission will be performed only if further conditions such as channel availability are met.
摘要翻译：使用ARQ技术公开了一种用于发送容错数据的方法和装置，其中执行错误数据的重传直到剩余的错误量是可接受的（例如，由于错误的错误数据不会被信息的接收者，其可以是具有附加纠错能力的人或更高级协议）。使用检测为错误的数据块（RLC）的数量来定义可靠性度量（RM），并且执行错误数据块的重传请求，直到达到期望的可靠性阈值（RT）。当可靠性测量（RM）在第一和第二阈值之间时，可以采用具有比第一阈值更高的值的附加阈值来请求可选重传。只有在满足诸如频道可用性等更多条件的情况下，才会进行重传。

摘要： The invention relates to retransmissions in wireless communication systems. It is proposed to reduce the retransmission delays by utilizing feedback associated with a lower protocol layer than the conventional feedback messages of the ARQ functionality. After sending a packet from a transmitter towards a receiver, the transmitter monitors the link for a low-level control signal from the receiver. The low-level control information can e.g. comprise power control commands or be related to link quality indicators. Based on this signal, it is decided whether a retransmission is to take place, e.g. at the transmitter or at an external control unit.

摘要： A device and method for controlling data unit communications between a sender and a receiver, and flexibly responding to a potential data loss event. Data units are transmitted from the sender to the receiver, and the receiver returns an acknowledgment data unit for each data unit received. If the receiver fails to receive a data unit, the sender retransmits the data unit in accordance with a data unit loss response procedure. If the potentially lost data unit is subsequently received, the sender determines whether the correctly received data unit was the initial data unit or the retransmission. If the correctly received data unit was the retransmission, the sender continues to transmit subsequent data units in accordance with the data unit loss response procedure. However, if the correctly received data unit was the initial data unit, the sender transmits subsequent data units in accordance with an excessive delay response procedure.

摘要： A device and method for controlling data unit communications between a sender and a receiver, and flexibly responding to a potential date loss event. Data units are transmitted from the sender to the receiver, and the receiver returns an acknowledgment data unit for each data unit received. If the receiver falls to receive a data unit, the sender retransmits the data unit in accordance with a data unit loss response procedure. If the potentially lost data unit is subsequently received, the sender determines whether the correctly received data unit was the initial data unit or the retransmission. If the correctly received data unit was the retransmission, the sender continues to transmit subsequent data units in accordance with the date unit loss response procedure. However, if the correctly received data unit was the initial data unit the sender transmits subsequent data units in accordance with an excessive delay response procedure.

摘要： A method of controlling a data unit sender is described. A flow control procedure for controlling the flow of data units sent by said data unit sender is conducted in dependence on acknowledgement messages from the receiver The flow control procedure utilizes (S103) at least one output limiting parameter (olp; cwnd) for placing a limit on the data units sender's current data send rate. A procedure is provided for detecting (S110) a data unit loss indication, in response to the detection of a data unit loss indication, performing (S311) a retransmission, subsequent to said retransmission (S311) waiting (S312) for an acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost, and distinguishing (S317) whether said acceptable acknowledgment message relates to an original transmission, and in response to distinguishing that said acceptable acknowledgment message does not relate to said original transmission, performing (S318) a congestion response step, while in response to distinguishing that said acceptable acknowledgment message relates to said original transmission, said output limiting parameter is adapted (S319) based on one or more duplicate acknowledgment messages received since receiving the last acceptable acknowledgment message that precedes the acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost.
