REDUNDANCY VERSION CONFIGURATION FOR A PROBABILISTIC CONSTELLATION SHAPING SCHEME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240121035 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. Redundancy versions of the message are configured based on the non-uniform distribution of symbols, with the same set of non-uniformly distributed systematic bits or at least a portion included 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.

• Wireless communications system utilizing non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping.
• Support for probabilistic constellation shaping (PCS) for message transmission.
• Configuration of redundancy versions based on non-uniform distribution of 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.
