Abstract: Systems and methods are disclosed for providing H-ARQ transmissions in respect of a set of horizontal code blocks are combined in a code. Retransmissions contain vertical parity check blocks which are determined from verticals from the set of horizontal code blocks. Once all the vertical parity check blocks have been transmitted, a new set may be determined after performing interleaving upon either the content of the horizontal code blocks, in the case of non-systematic horizontal code blocks, or over the content of encoder input bits in the place of systematic horizontal code blocks. The interleaving may be bitwise or bit subset-wise. The retransmissions do not contain any of the original bits. In the decoder, soft decisions are produced, and nothing needs to be discarded; decoding will typically improve with each retransmission.

Abstract: Aspects of the present disclosure provide a scheme for generating a multiple access (MA) signal that include mapping each of at least one stream of bits to generate a set of modulated symbols and transmitting the set of modulated symbols. The spreading signatures that are selected to map the at least one stream of bits are selected, at least in part, based on a set of compatibility rules. The spreading involves mapping each stream of bits using a respective spreading signature from a set of spreading signatures to generate a respective set of modulated symbols, wherein real spreading signature components of the spreading signatures are orthogonal to each other and imaginary spreading signature components of the spreading signatures are orthogonal to each other.

Abstract: Methods and systems are disclosed for symbol sequence generation and transmission for non-orthogonal multiple access (NoMA) transmission. A NoMA signal may be generated based on: (1) a first symbol sequence, the first symbol sequence determined from a set of input bits and associated with a first MA signature within a first MA signature space; (2) a second symbol sequence determined based on the first symbol sequence, the second symbol sequence being associated with a second MA signature within a second MA signature space; and (3) a symbol-to-resource element mapping applied to the second symbol sequence to produce the NoMA signal.

Abstract: An apparatus and method for transmitting data with conditional zero padding is provided. In accordance with an embodiment of the disclosure, a transmitter transmits data to a receiver by transmitting symbols such that each symbol is preceded by a cyclic prefix of a fixed length and the symbol conditionally includes enough zero padding to avoid ISI (Inter-Symbol Interference) between consecutive symbols. In some implementations, if the fixed length for cyclic prefixes is long enough to avoid ISI between consecutive symbols, then the symbols may omit zero padding. Otherwise, the symbols may include enough zero padding to avoid ISI between consecutive symbols. The zero padding may be zero tail or zero head.

Abstract: Methods and devices are disclosed for decoding multiple sparsely encoded data sequences in a wireless communications network. A received signal carrying multiple sparsely encoded data sequences is decoded by selecting a first plurality of the data sequences and performing multi-user decoding on the received signal to decode the first plurality of data sequences. Other data sequences are treated as noise. The plurality of data sequences is selected to meet a collision threshold for the multi-user decoding. Data sequences may be selected based on a collision contribution and signal quality metrics. A modified received signal is generated to remove signals associated with the multiple sparsely encoded data sequences which have been successfully decoded. The method may be performed for additional iterations to select a new plurality of data sequences, and perform the multi-user decoding on the modified received signal to decode additional data sequences, until a stopping condition is met.
