INDICATION ON PROBABILISTIC SHAPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17543432 titled 'INDICATION ON PROBABILISTIC SHAPING

Simplified Explanation

The present disclosure provides techniques for indicating the actual transport block size (TBS) on shaping encoding. Instead of using a compensated rate code, the disclosure supports using multiple actual TBS for a given nominal TBS to improve efficiency of the shaping encoder.

• The disclosure enables a transmitter to encode a payload size of bits with a shaping encoder to obtain a transport block (TB) with an actual TBS.
• The actual TBS is selected from a set of TBSs based on a nominal TBS.
• The transmitter then transmits an indication of the actual TBS to the receiver, allowing the receiver to decode the corresponding encoded bits.
• The transmitter then transmits the TB to the receiver.

Potential Applications

• This technology can be applied in wireless communication systems, such as cellular networks, to improve the efficiency of encoding and decoding processes.
• It can be used in various communication devices, including network entities and user equipment (UE), to enhance the overall performance of data transmission.

Problems Solved

• The disclosure addresses the issue of using a compensated rate code for a fixed number of output bits that may differ from the scheduled TBS, which can lead to inefficiencies in shaping encoding.
• By using multiple actual TBS for a given nominal TBS, the disclosure improves the efficiency of the shaping encoder and ensures accurate decoding of the transmitted data.

Benefits

• The use of multiple actual TBS allows for more efficient encoding and decoding processes, improving the overall performance of data transmission.
• By indicating the actual TBS to the receiver, the disclosure ensures accurate decoding of the transmitted data, reducing errors and improving the reliability of communication systems.

Original Abstract Submitted

Certain aspects of the present disclosure provide techniques for indicating actual transport block size (TBS) on shaping encoding. For example, in shaping encoding, instead of using a compensated rate code (e.g., by padding or truncating) for a fixed number of output bits that is often different from the TBS scheduled, the present disclosure supports using multiple actual TBS for a given nominal TBS to improve efficiency of the shaping encoder. A transmitter (e.g., a network entity or use equipment (UE)) may encode a payload size of bits with a shaping encoder to obtain a transport block (TB), which has an actual TBS. The actual TBS is selected from a set of TBSs based on a nominal TBS. The transmitter then transmits to a receiver, an indication of the actual TBS. The indication enables the receiver to decode the corresponding encoded bits. The transmitter then transmits the TB to the receiver.
