Abstract
Embodiments related to retransmission in a communication system are described and depicted. In one embodiment, a retransmission entity repeats a transmission of 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.
Claims33
A digital subscriber line (DSL) noise protection apparatus, the apparatus comprising:
- first circuitry to receive data transfer units from a downstream direction including at least one data transfer unit corrupted by noise;
- second circuitry to obtain a retransmission return message with a number of the data transfer units acknowledged;
- the second circuitry to determine a start of the data transfer units acknowledged based on a look back value;
- and
- the second circuitry to communicate the look back value in an upstream direction.
