Method and device for retransmission

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.

主权项

1. A method comprising:
determining a first value indicating a length of repetitive impulse noise events occurring on a communication system when transmitting data transfer units comprising data from a first device to a second device, wherein the first value indicates a length of the repetitive impulse noise events which corresponds to a length of a plurality of data transfer units; determining a second value indicating a period length of the repetitive impulse noise events occurring on the communication system; determining a parameter of a retransmission for the communication system based on the first and second value, wherein the parameter is used to determine a starting point for counting a number of consecutive correct received data transfer units, wherein the number of consecutive correct received data transfer units is provided in a retransmission return message.
