摘要： In one implementation, a transmission apparatus includes a protocol stack for a DSL transmission system, the protocol stack includes a retransmission functionality, the retransmission functionality being provided between a sublayer of a TPS-TC layer and a data link layer, the retransmission functionality having a fragment of a packet or a group of fragments of a packet as basic retransmission unit. The protocol stack may implement a service specific retransmission functionality such that for a first class of services retransmission protection is provided and for a second class of services no retransmission protection is implemented.

摘要： Embodiments related to retransmission in data communication systems are described and depicted. In one embodiment, a data packet is received and separated to a plurality of data fragments. Information indicating whether a fragment of the plurality of fragments is to be protected by retransmission is provided or information indicating whether a group of fragments is to be protected by retransmission is provided. A request for retransmission from the second transceiver unit to the first transceiver unit may be generated. Based on the request, one or more identified data fragments may be retransmitted.

摘要： One embodiment relates to a method of communicating data between a transmitter and a receiver of a communication system. In this method, a payload data stream is received from a network interface layer. The payload data stream includes data units eligible for retransmission and data units non-eligible for retransmission. These data units are grouped into containers, where a container is associated with a container identifier that distinguishes the container from other containers. The containers are grouped into data transmission units, where a data transmission unit includes at least one container along with redundancy information that facilitates error detection for that data transmission unit. The data transmission units are transmitted to the receiver as a transmission data stream. Other methods and systems are also disclosed.

摘要： One embodiment relates to a method of transmitting data from a transmitter to a receiver. In the method, a payload data stream is provided which comprises a plurality of payload data units. A container stream is formed which comprises a plurality of containers having respective container identifiers, where a container includes an integer number of the payload data units and where the container identifiers collectively establish a predetermined order for consecutive containers. A codeword stream is formed which comprises a plurality of codewords having respective redundancy information, where a codeword includes at least a portion of the container and where redundancy information of the codeword facilitates detection of erroneous data in the codeword. The codeword is transmitted from the transmitter to the receiver. Other methods and systems are also disclosed.

摘要： Embodiments related to retransmission in a communication system are described and depicted. In one embodiment, a retransmission entity repeats a transmission of a data transfer unit by the device after a predetermined number of other transmitted data transfer units has been transmitted. The retransmission entity may also determine whether a measure for a time period since the first transmission of the data transfer unit by the device has exceeded a predetermined threshold and to provide a final transmission of the data transfer unit based on the determining that the measure for the time period has exceeded the predetermined threshold.
