Additional error protection for wireless transmission

摘要

Certain aspects of the present disclosure provide methods and apparatus for enhancing error protection for wireless transmissions. Certain aspects are generally directed to a method for wireless communications by an apparatus, comprising receiving a packet from another apparatus, the packet comprising a first error check value. The packet may further comprise a second error check value generated based at least in part on information known or expected by the apparatus. The apparatus may then perform a first and second error check, based at least in part on the first and second error check values and discard the packet based at least in part on performing the first and second error check.

主权项

1. An apparatus for wireless communications, comprising:
a receiver configured to receive a packet from another apparatus, the packet comprising a first error check value generated based on a remaining portion of the packet and a second error check value generated based on information known or expected by the apparatus and other information transmitted in the packet; and a processing system configured to:
perform a first error check of the packet based on a comparison of the first error check value and an error check value generated by the apparatus for the remaining portion of the packet,reconstruct a value of the known or expected information based on the second error check value and the other information transmitted in the packet,perform a second error check of the packet based on comparison of the reconstructed value and an expected value of the information known or expected by the apparatus, anddiscard the packet if either the first error check fails or the reconstructed value differs from the known or expected value.
