Techniques for redundancy generation of polar codes during wireless communications

Abstract:

Methods and apparatuses for wireless communications are described. In an aspect, a method and apparatus may include determining that a second transmission is decoded incorrectly in response to a first received indication on a communication channel. The method and apparatus may further include transmitting, on the communication channel, a third transmission and a fourth transmission based on a determination that the second transmission is decoded incorrectly, wherein the third transmission corresponds to a coded bit set of the third transmission including a first group of information bits of a coded bit set of a first transmission and a second group of information bits of a coded bit set of the second transmission and the fourth transmission corresponds to a coded bit set of the fourth transmission including a combination of the coded bit sets of the first transmission, the second transmission, and the third transmission.
