Communication system with repeat-response combining mechanism and method of operation thereof
First Claim
1. A requesting device of a communication system comprising:
- an antenna configured to;
receive preceding data including a communication content corresponding to an instance of a transmission block;
transmit a repeat request corresponding to an error detection status for the preceding data;
receive a receiver signal corresponding to a further instance of the transmission block subsequent to the repeat request;
a control unit, coupled to the antenna, configured to;
determine a previous communication value resulting from decoding the preceding data for generating the error detection status of the preceding data;
identify a repeat data corresponding to the repeat request from the receiver signal;
generate an accumulation output including systematic channel log-likelihood ratios (LLRs), subsequent to de-interleaving the receiver signal and de-puncturing the repeat data, based on combining the preceding data and the repeat data, and a repeat detection result and a preceding detection result; and
determine the communication content based on decoding the accumulation output using the previous communication value and the accumulation output.

Abstract
A communication system includes: a validation module configured to transmit a repeat request corresponding to a preceding data including a communication content; an inter-block processing module, coupled to the validation module, configured to determine a previous communication value based on the preceding data; a detection module, coupled to the inter-block processing module, configured to identify a repeat data corresponding to the repeat request from a receiver signal; an accumulator module, coupled to the detection module, configured to generate an accumulation output based on the preceding data and the repeat data; and a decoding module, coupled to the accumulator module, configured to determine the communication content using the previous communication value and the accumulation output across instances of transmission blocks for communicating with a device.

11. A method of operation of a requesting device in a communication system comprising:
-
receiving preceding data including a communication content corresponding to an instance of a transmission block; transmitting a repeat request corresponding to an error detection status for the preceding data; receiving a receiver signal corresponding to a further instance of the transmission block subsequent to the repeat request; determining with a control unit a previous communication value resulting from decoding the preceding data for generating the error detection status of the preceding data; identifying a repeat data corresponding to the repeat request from the receiver signal; generating an accumulation output including systematic channel log-likelihood ratios (LLRs), subsequent to de-interleaving the receiver signal and de-puncturing the repeat data, based on combining the preceding data and the repeat data, and a repeat detection result and a preceding detection result; and determining the communication content based on decoding the accumulation output using the previous communication value and the accumulation output. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
