    Abstract: Embodiments pertain to systems, methods, and component devices for dynamic non-orthogonal multiple access (NOMA) communications. A first example embodiment includes user equipment (UE) configured to receive a first downlink control indicator (DCI) from an evolved node B (eNB) and process the first subframe as a first higher power NOMA subframe in response to a first power ratio signal. The DCI includes the first power ratio signal for a first NOMA subframe. The UE may then receive, from the eNB, a second DCI, the second DCI comprising a second power ratio signal for a second subframe and process, by the UE, the second subframe as a second lower power NOMA subframe in response to the second power ratio signal. Additional embodiments may further use another DCI with a third power ratio signal to configure the UE to receive orthogonal multiple access (OMA) communications.

    Abstract: Embodiments of User Equipment (UE), an Evolved Node-B (eNB), and methods for channel quality indicator (CQI) feedback are disclosed herein. An aperiodic CQI type parameter received at the UE may indicate a CQI type for use in a determination of an aperiodic CQI based on signals received from the eNB. Channel-state information reference signals (CSI-RS) may be used when single-user multiple-input multiple-output (SU-MIMO) signals are received. Physical downlink shared channel (PDSCH) blocks may be used when multi-user multiple-input multiple-output (MU-MIMO) signals are received. The aperiodic CQI may be transmitted to the eNB as part of an aperiodic CQI measurement report. In addition, periodic CQI measurement reports may also be transmitted to the eNB and may include periodic CQIs that are based on CSI-RS received at the UE.

    Abstract: Apparatuses, methods, and computer readable media are disclosed. A STA to detect a HE SIG may be configured to detect the HE SIG based on at least one from the following group: a flipped reserved bit, a scrambled portion of the HE SIG, and a rotation of a signal constellation of the HE SIG different than legacy rotations of: a rotation of a first signal constellation and no rotation of a second signal constellation, and no rotation of the first signal constellation and a rotation of the second signal constellation. The STA may determine that a reserved bit is the flipped reserved bit based on a bit being reversed from a legacy standard. The STA may unscramble a received signal field, determine whether a CRC indicates the HE-SIG contains errors, and if the CRC indicates there are no errors, then determine that the signal field is the HE SIG.

    Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.
