US 2023/0155729 A1 · SYSTEM AND METHOD FOR RECEPTION OF WIRELESS LOCAL AREA NETWORK PACKETS WITH BIT ERRORS

Abstract

A method in a first wireless device (WD) supporting wireless communication with a second WD is described. A plurality of wireless packets is received from the second WD including at least a first wireless packet. At least another wireless packet of the plurality of wireless packets is one of a retry packet and a repeat packet of the first packet. Each wireless packet of the plurality of wireless packets includes a plurality of bits and a first group of bits. For each received wireless packet, the plurality of bits corresponding to the received wireless packet is de-spread, and the first group of bits is correlated with a predetermined group of bits. The method further includes performing a majority vote based on the correlation of the first group of bits of each received wireless packet and creating a corrected packet based in part on the majority vote.

Dependent claims

A method for a first wireless device (WD) supporting wireless communication with a second WD, the method comprising:

receiving a plurality of wireless packets from the second WD including at least a first wireless packet and a plurality of retried wireless packets, each wireless packet of the plurality of wireless packets comprising at least a first group of bits, the first group of bits corresponding to a known set of bits;
for each received wireless packet of the plurality of wireless packets:
correlating the first group of bits with the known set of bits;
comparing a result of the correlating to a first threshold;
and
creating a corrected packet based at least in part on whether a number of comparison results exceeding the first threshold is greater than N out of M received packets, M being an integer and N being an integer greater than N.

A first wireless device (WD) supporting wireless communication with a second WD, the first WD comprising:

a transmitter receiver configured to:
receive a plurality of wireless packets from the second WD including at least a first wireless packet and a plurality of retried wireless packets, each wireless packet of the plurality of wireless packets comprising at least a first group of bits, the first group of bits corresponding to a known set of bits;
and
processing circuitry in communication with the transmitter receiver, the processing circuitry being configured to, for each received wireless packet of the plurality of wireless packets:
correlate the first group of bits with the known set of bits;
compare a result of the correlating to a first threshold;
and
create a corrected packet based at least in part on whether a number of comparison results exceeding the first threshold is greater than N out of M received packets, M being an integer and N being an integer greater than N.
