    摘要： A node (110, 115) receives (804) transmissions associated with a given set of information bits, wherein each of the transmissions use a different polar code and share one or more information bits of the given set of information bits. The node determines (808), at each of a plurality of polar decoders (505, 605) of the node, soft information for each information bit included in an associated one of the transmissions, wherein each of the plurality of polar decoders is associated with a different transmission of the transmissions. The node provides (812), from each polar decoder of the plurality to one or more other polar decoders of the plurality, the determined soft information for any information bits shared by their respective associated transmissions, and uses (816) the provided soft information in an iterative decoding process to decode one or more of the received transmissions.

    摘要： Real-time selection of interference cancellation schemes based on transmission parameters and amount of resource overlap between the desired payload and the interfering payload. Codeword level interference cancellation may be performed where the signal quality of the interfering signal indicates that the interfering payload will be decoded correctly. When performed, codeword level interference cancellation may be monitored to determine if decoding the interfering payload is converging. Other interference cancellation schemes may be selected based on the signal quality of the interfering signal or non-converging decode of the interfering payload. The number of iterations for iterative decoding in codeword level interference cancellation may be dynamically selected. The decoder output (e.g., soft bits) may be used to perform interference cancellations before the decoder is fully converged. Iterative decoding may be performed in multiple passes and soft decision output form one pass may be used to initialize the decoder for a subsequent pass.
