SOFT BUFFER PARTITION FOR SUPERPOSITION CODING

Title:

SOFT BUFFER PARTITION FOR SUPERPOSITION CODING

Document Type and Number:

WIPO Patent Application WO/2016/107570

Kind Code:

A1

Abstract:

When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, it is helpful if the soft buffer at the receiver is reserved not only for the desired transport blocks (TBs) but also for the interfering TBs handled by the CW-IC. In so doing, the soft channel bits of interfering TBs at multiple (re) transmissions can be combined to enhance the success rate of data decoding. A soft buffer partition method for the soft channel bits of the desired and interfering TBs in the superposition coding scheme is proposed. The proposed method has a full flexibility in adjusting the soft buffer sizes for the desired and interfering TBs.
