  • System and method of waveform design for operation bandwidth extension
    Patent number: 11050503
    Abstract: Different numerologies may be used to communicate orthogonal frequency division multiplexing (OFDM)-based signals over different frequency sub-bands of a given carrier. This may allow the OFDM-based signals to efficiently support diverse traffic types. In some embodiments, the numerology of OFDM-based signal depends on a bandwidth of the frequency sub-band over which the OFDM-based signals are transmitted. In some embodiments, the OFDM-based signals are filtered OFDM (f-OFDM) signals, and the pulse shaping digital filter used to generate the f-OFDM signals allows the receiver to mitigate interference between adjacent f-OFDM signals upon reception, thereby allowing f-OFDM signals to be communicated over consecutive carriers without relying on a guard band.

  • Method and system for non-orthogonal multiple access communication
    Patent number: 11050532
    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.

  • Method for communication and an apparatus thereof
    Patent number: 11051330
    Abstract: A base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.

  • System and method of configurable sequence usage for transmission reception points
    Patent number: 11051257
    Abstract: Systems and methods are provided that allow a transmit receive point (TRP) that is a member of a group of TRPs to convey a characteristic of the group through the transmission of a synchronization sequence. A transmit receive point in a first group of TRPs transmits with a first synchronization sequence. A TRP in a second group of TRPs transmits with a second synchronization sequence, the first and second synchronization sequences being different from each other. The TRPs of the first group share a common first characteristic and the TRPs of the second group share a common second characteristic. The transmission of the first synchronization sequence conveys the first common characteristic, and the transmission of the second synchronization sequence conveys the second common characteristic.

    Abstract: Some embodiments of the present disclosure provide control signaling mechanisms to support data transmission by a user equipment (UE) that is in the RRC_INACTIVE state and, more generally, in any inactive state. Beyond simply supporting data transmission by a user equipment that is in the RRC_INACTIVE state, aspects of the present application provide mechanisms for configuring the UE for preamble transmission or sounding reference signal (SRS) transmission and for toggling between such transmissions. Aspects of the present application relate to mechanisms for enabling Timing Advance estimation, which mechanisms are not burdened with high overhead and which allow the UE to remain in the RRC_INACTIVE state.

  • SYSTEM AND METHOD FOR BANDWIDTH UTILIZATION
    Publication number: 20210185698
    Abstract: Methods of bandwidth utilization are provided. Within a scheduling bandwidth, which may be an entire carrier bandwidth or a sub-band, scheduling is used to reserve a guard zone at the edge of the scheduled bandwidth. This can be based on the frequency localization capabilities of a transmitter that is to be scheduled. The guard zone may be defined to a resolution that is the same as the scheduling resolution in which case the guard zone is defined entirely through scheduling. Alternatively, the guard zone may be defined to a resolution smaller than the scheduling resolution in which case scheduling and further signaling may be employed to define the guard zone.

  • System and Method for UE Fountain Relay Based Network
    Publication number: 20210160963
    Abstract: System and method embodiments are provided for enabling flexible and reliable UE-to-UE based relay. The embodiments include using fountain codes for combining signals at a suitable network layer higher than a media access control (MAC) sub-layer and using a MAC sub-layer hybrid automatic repeat request (HARQ) transmission scheme. When a relay UE in a UE group for joint reception receives, from a network access point, a data packet intended for a destination UE in the UE group and including fountain code at the higher network layer, the relay UE sends the data packet to the destination UE and returns a HARQ ACK message at the MAC sub-layer to the access point. The destination UE then receives and decodes the data packet. Subsequently, upon receiving the entire data, the destination UE sends an ACK message at the higher network layer to the access point.
