Error detection in wireless communications using sectional redundancy check information
First Claim
1. A method of wirelessly transmitting data in accordance with a radio technology, comprising:
- obtaining, by an encoder of a wireless transmission device, a payload to be transmitted;
partitioning, by the encoder, the payload into a sequence of one or more payload sections;
for each respective payload section in the sequence of one or more payload sections;
deriving, by the encoder, sequential redundancy check information corresponding to all payload sections in the sequence of one or more payload sections starting from a first payload section to the respective payload section;
merging, by the encoder, the respective payload section and the sequential redundancy check information corresponding to the respective payload section with a sequence of bits;
generating, via the encoder, a codeword by encoding the sequence of bits for transmission; and
transmitting, via a transmitter of the wireless transmission device, the codeword across a wireless channel in accordance with the radio technology.

Abstract
Certain aspects of the present disclosure relate to techniques and apparatus for increasing decoding performance and/or reducing decoding complexity. An exemplary method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of payload sections, deriving redundancy check information for each respective payload section of the plurality of payload sections, merging the redundancy check information for each payload section with the plurality of payload sections to form a sequence of bits, and generating a codeword by encoding the sequence of bits using an encoder. Other aspects, embodiments, and features are also claimed and described.
