  • Patent number: 10887139
    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.

  • Patent number: 10735143
    Abstract: Methods of transmitting and receiving a set of bits are provided. In the transmitting method, some of the bits are mapped to modulated symbol, and some of the bits map to a subset of transmission resources out of a first set of transmission resources. The modulated symbol is transmitted using the subset of transmission resources. At the receiver, a modulated symbol is received using a subset of transmission resources. Some bits are recovered by demodulating the demodulated symbol, and some of the bits are recovered based on the subset of transmission resources over which the modulated symbol was received.

  • Patent number: 10721114
    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.

  • Patent number: 10700912
    Abstract: A bit-level operation may be implemented prior to modulation and resource element (RE) mapping in order to generate a NoMA transmission using standard (QAM, QPSK, BPSK, etc.) modulators. In this way, the bit-level operation is exploited to achieve the benefits of NoMA (e.g., improved spectral efficiency, reduced overhead, etc.) at significantly less signal processing and hardware implementation complexity. The bit-level operation is specifically designed to produce an output bit-stream that is longer than the input bit-stream, and that includes output bit-values that are computed as a function of the input bit-values such that when the output bit-stream is subjected to modulation (e.g., m-ary QAM, QPSK, BPSK), the resulting symbols emulate a spreading operation that would otherwise have been generated from the input bit-stream, either by a NoMA-specific modulator or by a symbol-domain spreading operation.

  • Publication number: 20200186189
    Abstract: According to aspects of the disclosure, there is provided a method for a UE to select or be assigned or configured with a spreading sequence that is based on one or more communication parameters such as receiver type, receiver capability, SE, TBS, MCS, traffic load, PAPR requirement, MCL, number of layers, overloading, reliability requirement, transmission power consumption, number of active UEs, and transmission latency constraint, etc. In some embodiments, the spreading sequence may be related to a performance metric associated with an above parameter (PAPR, BLER, etc.). In some embodiments, this is achieved by associating spreading sequences with parameters or performance metrics, or both. In some instances the spreading sequences may be arranged or ordered in a manner to reduce signaling overhead (e.g., signaling an index is more efficient than signaling a value of a metric, and ordering correlates the index to the value).

  • Publication number: 20200092057
    Abstract: A system and method of non-orthogonal multiple access (NoMA) transmission using a configurable NoMA scheme is provided. A bit level processor, a modulation block, a phase and amplitude adjuster, and a symbol to resource element mapper collectively produce a NoMA signal for output or transmission. A NoMA scheme implemented by the system and method is configurable through one or more NoMA configuration inputs that configure one or more of the bit level processor, the modulation block, the phase and amplitude adjustment block and the symbol to resource element mapper. A multiple access (MA) signature produced by the apparatus once configured for the particular NoMA scheme is selectable through one or more MA signature inputs.

  • Publication number: 20190166624
    Abstract: A diversity channel for data transmission is obtained by communication equipment. The diversity channel indicates communication resources that are assigned to the communication equipment, and is from a set of diversity channels that are consistent with codewords of a linear code. The communication equipment also transmits a data transmission using the communication resources indicated by the diversity channel. The diversity channel assignment could be determined, by network equipment for example, and information that identifies the diversity channel could be transmitting to the communication equipment. Such information could be explicitly or implicitly signaled to the communication equipment. A set of diversity channels could be generated directly as codewords of one or more linear codes, or additional operations could be applied to such codewords, and possibly other information that is not generated using a code, to provide a diversity channel set.
