  • Patent number: 11172473
    Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

    Abstract: Methods, systems, and devices for wireless communications are described. In some cases, devices such as band limited (BL) or coverage enhancement (CE) user equipment (UE) having limited transmitting and receiving capability may operate using a subset of a system bandwidth of a carrier (e.g., narrowbands). To support frequency hopping or frequency diversity in transmissions, for example, such devices may utilize retuning when a resource allocation moves from a first narrowband to a second narrowband. Retuning, however, may create challenges when transmitting and receiving capability is limited. Aspects of this disclosure may support a flexible starting physical resource block (PRB) for indicating new resource allocations for BL or CE UEs. In some aspects, a UE is disclosed which may retune between consecutive transmission time intervals (TTIs) or subframes, for example, from a first tuning band to a second tuning band (e.g., a newly defined retuning narrowband).

    Abstract: Based on information from a controller scheduling data traffic in a processing arrangement, a super capacitor unit is activated, whereby reactive power is fed to a system bus of said power system. The controller is configured to have information at time t(n) about the data traffic workload of the processing arrangement at time t(n+1). By triggering discharge of the super capacitor unit based on super capacitor data at time t(n+1), transients on a system bus voltage are, at least in part, smoothed out at time t(n+1), which reduces the need for reactive power of the power system, where said transients are related to the data traffic workload of the processing arrangement. The power efficiency of the power system can be improved by 3-4% by the reduction of the need for reactive power from a power grid, for which reason the electrical bill of an operator is reduced.

  • Patent number: 10958297
    Abstract: There is provided mechanisms for mitigating interference in a communications network. A method is performed by a network node. The method comprises obtaining a packet. The packet has been wirelessly received in an uplink direction by a transmission and reception point of the network node and from a packet sender. The packet is indicative of scheduled transmission of a further packet within a predefined time interval from the transmission and reception point has wirelessly received the packet. The method comprises determining beamforming weights such that interference caused by transmission from the transmission and reception point of the network node in a downlink direction being reversed to the uplink direction is less than a threshold interference value. The method comprises initiating transmission in at least one beam using the determined beamforming weights. The beamforming weights are used for the transmission at least within the predefined time interval.

  • Patent number: 10958395
    Abstract: The present disclosure discloses a method and a system for transmitting DFT-s-OFDM symbols. A data sequence for transmitting as an OFDM symbol is received as input from a data source. A reference sequence for transmitting along with the data sequence as the OFDM symbol is generated and time-multiplexed with the data sequence, to generate a multiplexed sequence. Thereafter, a Discrete Fourier Transform (DFT) operation is performed on the multiplexed sequence to generate a DFT-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) symbol that is further processed for transmitting over a channel. The transmission of the reference sequence and the data sequence in a single OFDM symbol provides better bandwidth utilization and flexibility in modulation of the reference sequence and the data sequence.

    Abstract: In order to perform efficient communications. A terminal apparatus includes a higher layer processing unit configured to configure a subcarrier spacing of a physical channel, based on a first parameter, and a transmission unit configured to perform an uplink transmission by using the physical channel. In a case that transmissions on a first physical channel configured with a first subcarrier spacing and a second physical channel configured with a second subcarrier spacing occur in one serving cell, and that the second subcarrier spacing is wider than the first subcarrier spacing, the transmission unit allocates a transmit power on a priority basis to the second physical channel.

    Abstract: Systems and methods for utilizing millimeter-wave radio components in synthesizing microwave signals. A first up-conversion frequency generated using millimeter-wave radio components is used to up-convert a baseband signal into a first millimeter-wave signal, which is then down-converted into a microwave signal using a second and lower down-conversion frequency generated using additional millimeter-wave radio components. Using millimeter-wave conversion frequencies allows for tight integration of multiple transmission and reception chains while facilitating good coexistence of different microwave channels, and further allows for a wide span of frequencies over which microwave transmissions can be made.
