US 2023/0155719 A1 · TRANSMISSION PUNCTURING SCHEMES FOR RATELESS CODING

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for signaling mechanisms associated with transmission puncturing schemes for rateless coding. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message and may perform transmission puncturing to adapt a bit rate of related signal transmissions. The transmitting device may signal an indication of the transmission puncturing scheme, and potentially one or more modifications to the transmission puncturing scheme, to a receiving device via control signaling. The transmitting device may modify the transmission puncturing scheme in accordance with prioritizing retransmissions for some cumulative portions of the message ahead of other cumulative portions, such as by granting prioritized cumulative portions of the message relatively earlier transmission occasions in the transmission puncturing scheme.
