US 2025/0158739 A1 · SYSTEMS AND METHODS OF INITIATING RETRANSMISSION REQUESTS

Abstract

A communication system is described, among other things. An illustrative system is disclosed to include one or more decoding circuits to perform forward error correction for a received data block in a physical layer and one or more cyclic redundancy check circuits to perform a cyclic redundancy check based on a first output of the decoding circuits and a cyclic redundancy check code generated in the physical layer based on the received data block. In response to one or more of a second output of the decoding circuits and an output of the cyclic redundancy check circuits, a retransmission request of the data block is initiated.

Claims20

Dependent claims

A communication system, comprising:

one or more decoding circuits configured to determine one or more locations of one or more errors in a data block;
a comparator circuit configured to compare a number of the one or more locations of the one or more errors in the data block with a number of expected errors in the data block and output a result as first output;
and
a switching circuit configured to initiate a retransmission request for the data block based on at least the first output from the comparator circuit.
