  • Patent number: 11070411
    Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (?), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,x?) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

  • Patent number: 11070245
    Abstract: A transmission method, and corresponding transmitter are provided that use a combination of sparse symbol mapping with non-sparse spreading. This can be used for a low-PAPR multiple access scheme where good performance is achieved by sparse domain multi-user detection. The provided method uses per-frequency block time-domain non-sparse spreading across sparse blocks which provides PAPR reduction. Sparsity patterns are partitioned into groups that allows PAPR reduction. The method may be used to support the transmission of a single-carrier signal, e.g. DFT-spread signal, to provide PAPR reduction. More generally the provided method can use any low-PAPR waveform, for example any single-carrier waveform or any single-subcarrier waveform.

  • Patent number: 11038641
    Abstract: Systems and methods are provided in which uplink transmission of pilot uses time-frequency resources that overlap with time-resources for the uplink transmission of data, by the same UE or different UEs. This can result in a decrease in pilot overhead, or if longer pilot sequences are used, can result in a decrease in collision probability. In a group-based approach, UEs are organized into groups, and each group is allocated the same resources for pilot and data.

  • Patent number: 11039429
    Abstract: Methods and apparatus are provided for wireless communication in which a downlink control information (DCI) is transmitted in a physical downlink control channel (PDCCH) in a first bandwidth part (BWP). A UE is responsible for determining a starting resource block (RB) for a data transmission allocated by the DCI based on a value of a frequency domain resource allocation field in the DCI, a reference RB, and a reference size of a second BWP. The data transmission can then be transmitted, in the case of, for example, PUSCH, by a UE or received, in the case of, for example, PDSCH.

  • Patent number: 10945277
    Abstract: A user equipment (UE) receives control signaling in a scheduling bandwidth part (BWP). The control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE. The control signaling aligns with a time unit boundary, such as a slot boundary, that is associated with the scheduling BWP. In the event that a scheduled BWP for a UE has a different numerology than a scheduling BWP that is currently active for the UE, the UE could switch from the scheduling BWP to the scheduled BWP based on a control signaling monitoring periodicity of the scheduled BWP.

  • Publication number: 20210067392
    Abstract: Aspects of the present application use a linear transformation of a sparse mapped single carrier transmission at a transmitter, for which a comparable inverse transform of the linear transform applied at the transmitter can be applied at the receiver. The linear transform reduces the sparsity of sparse mapped symbols. The use of the linear transform to reduce the sparsity enables peak-to-average power ratio (PAPR) and/or cubic metric to be reduced as compared to if the linear transform is not used. The linear transforms may be implemented in a block-wise manner, element-wise manner or combination thereof.

  • Patent number: 10938876
    Abstract: Methods and devices are disclosed for encoding and transmitting data sequences for low data rate applications. An encoded data sequence is transformed and used to shape a multi-carrier pulse to create a narrow-band signal for transmission. Time domain tails of the narrow-band signal may be removed to decrease overhead. The data may be first encoded to create a sparse modulated data sequence. Multi-carrier pulse shaping may be carried out using frequency division multiplexing (FDM) or filter bank multi-carrier (FBMC) techniques. Alternatively, single carrier pulse shaping may be used to create the narrow-band signal.

  • Patent number: 10826745
    Abstract: Embodiments are provided for guard band utilization for synchronous and asynchronous communications in wireless networks. A user equipment (UE) or a network component transmits symbols on data bands assigned for primary communications. The data bands are separated by a guard band having smaller bandwidth than the data bands. The UE or network component further modulates symbols for secondary communications with a spectrally contained wave form, which has a smaller bandwidth than the guard band. The spectrally contained wave form is achieved with orthogonal frequency-division multiplexing (OFDM) modulation or with joint OFDM and Offset Quadrature Amplitude Modulation (OQAM) modulation. The modulated symbols for the secondary communications are transmitted within the guard band.
