  • Patent number: 10880033
    Abstract: A two stage scrambling design is provided for generating and decoding Resource Spread Multiple Access (RSMA) modulated streams. A User equipment (UE) scrambles each data stream of a set of data streams using a first scrambling sequence to generate a first set of scrambled data streams, and then scrambles the first set of scrambled data streams using a second scrambling sequence to generate a second set of scrambled data streams, wherein the second scrambling sequence is longer than the first scrambling sequence. The UE then transmits the second set of scrambled data streams. A receiving base station determines the first and second scrambling sequences used by the UE and decodes the transmissions received from the UE based on the determined scrambling sequences.

  • Patent number: 10862722
    Abstract: Methods, systems, and devices for wireless communications are described that provide for concurrent reference signal transmissions using common resources, such as demodulation reference signal (DMRS) transmissions, from a number of non-orthogonal multiple access (NOMA) transmitters. Different transmitters may use different sequences for reference signal transmissions, which may allow a receiver, such as a wireless base station, to decode the reference signal transmissions for each NOMA transmitter and perform channel estimation for each NOMA transmitter. The reference signal transmissions may be asynchronous with a bounded timing offset or quasi-synchronous, and the reference signal sequence selection may provide for relatively reliable channel estimation and coherent demodulation.

  • Patent number: 10630349
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may divide a data stream into multiple data sub-streams. The wireless device may map the data sub-streams to a set of layers of a multi-layer modulated stream. The wireless device may encode, rate match, modulate, spread and scramble the set of layers before combining them into a combined data stream. The number of layers in the set of layers may be configurable. The wireless device may apply scrambling sequences to the layers. An additional phase rotation or power scaling factor may be applied to each layer. The layers may then be synchronized and combined into a combined data stream. A set of combined data streams may be mapped to multiple-input, multiple-output (MIMO) layers. The wireless device may precode the MIMO layers, map the MIMO layers to tones, and transmit the combined data streams.
