  • Patent number: 11924818
    Abstract: This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve a desired amplitude distribution. Some implementations more specifically relate to performing an encoding operation to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some implementations of the non-uniform distribution, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. Some implementations enable the tracking of MPDU boundaries to facilitate successful decoding by a receiving device. Additionally or alternatively, some implementations enable the determination of a packet length after performing the amplitude shaping, which enables a transmitting device to determine the number of padding bits to add to the payload and to signal the packet length to a receiving device so that the receiving device may determine the duration of the packet.

  • Patent number: 11910391
    Abstract: Techniques for implementing an uplink control channel in Non-Orthogonal Multiple Access (NOMA) asynchronous transmissions are disclosed. The techniques described herein provide an additional control channel in NOMA transmissions for a user equipment (UE) (102) to indicate certain information to a base station (106) to enable the base station (106) to detect and decode the data transmitted by the UE (102). For example, uplink control information (UCI) is transmitted (406) via an uplink control channel in connection with a group user equipment identifier (group UE-ID) to enable the base station (106) to detect and decode the UCI. After decoding (506) the UCI based on the group UE-ID, the base station (106) obtains information usable to distinguish (508) the UE (102), such as a UE-specific ID, as well as to detect (510) and decode (512) a data transmission from the UE (102) on an uplink data channel.

  • Patent number: 11876657
    Abstract: A user equipment (UE) (30) is configured to enhance Demodulation Reference Signals (DM-RS) in order to reduce the Peak-to-Average Power Ratio (PAPR) to the same level as for data symbols. To accomplish this function, the UE obtains a first initialization value that is calculated based on one of a first parameter (e.g., cell ID) and a second parameter and a scrambling code ID. The UE then maps the first initialization value to either a first Code Division Multiplexing (CDM) group or a second CDM group based on the scrambling code ID. The mapping associates the first initialization value with the first or second CDM group such that the initialization value is used when generating a demodulation sequence for that CDM group.
