    Abstract: Some embodiments of the present disclosure provide for a determination, transmission, and reception of lists of visible virtual transmission points. A virtual transmission point is defined based on a signal from a transmission-reception point reflecting off a reflector before arriving at a location in a wireless communication environment. On the basis of the lists and the location of a given device, the transmission-reception point or a device in the environment may reconstruct and track channel subspaces related to a communication. The channel subspaces may relate to angles of departure of signals that reach the given device. The channel subspaces may relate to the angles of arrival of signals that reach the given device.

    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).

    Abstract: Systems, methods, and apparatuses for providing waveform adaptation are provided. In an example, a method is provided for identifying a plurality of candidate waveforms, and selecting one of the candidate waveforms for data transmission. The candidate waveforms may be identified in accordance with one or more criteria, such as a transmission capability of the transmitting device, a reception capability of the receiving device, a desired Peak-to-Average-Power-Ratio (PAPR) characteristic, adjacent channel interference (ACI) rejection requirements, spectrum localization requirements, and other criteria. The waveform selected for data transmission may be selected in accordance with one or more waveform selection criteria, such as traffic characteristic, application types, etc.

    Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

    Abstract: Higher rates of data communication may be utilized for downlink than for uplink. However, the decoding complexity of Sparse Code Multiple Access (SCMA) may become prohibitive for very high rates, resulting from, for example, a large number of layers, for very large constellations, or a combination of the two. Methods and transmitters are provided herein for transmitting that has been generated to reduce complexity at the receiver and methods and receivers are provided herein for receiving and decoding a received signal with reduced complexity. The reduced complexity in part is provided by the ability to maintain real and imaginary parts of a transmitted signal independent from one another.

    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.
