Title: Unequal erasure protection for prioritized data transmission
Inventor: LIU KANGQI
IPC: H04L1/00
Filed: 2020-05-08
Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may use a fountain code scheme (e.g., a Luby transform (LT) code scheme or a rapid tornado (Raptor) code scheme) to encode a set of source symbols transmitted to a receiving device based on one or more priorities associated with the set of source symbols. Similarly, a receiving device may decode source symbols based on the associated priorities. In some examples, the transmitting device may use a precoding process that maps source symbols to a set of intermediate symbols, where the set of intermediate symbols includes a quantity of copies of each source symbol based on the priority of each source symbol. Additionally or alternatively, the set of source symbols may have a non-uniform distribution, where source symbols with a higher priority may have a higher probability of being selected and combined into encoding symbols.
