REDUNDANCY VERSION CONFIGURATION FOR A PROBABILISTIC CONSTELLATION SHAPING SCHEME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18263671 titled 'REDUNDANCY VERSION CONFIGURATION FOR A PROBABILISTIC CONSTELLATION SHAPING SCHEME
Simplified Explanation
The abstract describes methods, systems, and devices for wireless communications that utilize non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for message transmission. The device configures redundancy versions based on the non-uniform distribution of symbols and may include the same set of non-uniformly distributed systematic bits in each redundancy version. Multiple modulation and coding scheme (MCS) values are used to modulate the redundancy versions, with a first MCS value for non-uniformly distributed symbols and a second MCS value for uniformly distributed symbols.

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may In use non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for transmission of a message. To provide a coding gain with one or more retransmissions of the message, the device may configure redundancy versions based on the non-uniform distribution of one or more symbols. In some examples, the device may include the same set of non-uniformly distributed systematic bits or at least a portion of non-uniformly distributed systematic bits in each redundancy version of the message. Additionally or alternatively, the device may use multiple modulation and coding scheme (MCS) values to modulate one or more of the redundancy versions, where a first MCS value is used to modulate non-uniformly distributed symbols and a second MCS value is used to modulate uniformly distributed symbols.
