  • Patent number: 11662393
    Abstract: It is possible to determine, with a simple configuration, that the connection direction of a cable is the reverse direction. A cable is connected for use between a transmission device and a reception device, and transmits data in one direction. A connection direction determination unit determines whether the connection direction is the reverse direction, on the basis of a result of voltage monitoring at a predetermined position on a power-supply line. When the connection direction is determined to be the reverse direction, the information transmission unit transmits information indicating that the connection direction is the reverse direction, to the transmission device or the reception device.

    Abstract: An electronic device may include wireless circuitry with a baseband processor, a digital transmitter, a digital-to-analog-converter (DAC), and an antenna. The baseband processor may produce baseband signals. The digital transmitter may generate self-interference-compensated signals based on the baseband signals. The DAC may generate radio-frequency signals for transmission by the antenna based on the self-interference-compensated signals and square-wave local oscillator waveforms. The digital transmitter may include a self-interference canceller that generates the self-interference-compensated signals. The self-interference-compensated signals may mitigate the creation of self-interferer repetition replicas that land on the carrier frequency of the radio-frequency signals. This may allow the radio-frequency signals to be free from error vector magnitude degradation and spectral regrowth that would otherwise be produced due to self-interference in the radio-frequency signals output by the DAC.

  • Patent number: 11533113
    Abstract: Techniques are presented to improve the accuracy of and reduce the time required for calibration of an in-phase/quadrature (I/Q) transmission circuit. A measurement receiver measures the I/Q mismatch, where an RF phase shift is introduced to distinguish between the transmitter and measurement receiver I/Q mismatches. Rather than assuming an amount of introduced phase shift, a measurement is used to estimate the phase shift. This phase estimate is then used to determine and correct the I/Q mismatch in the transmitter and measurement receiver. An iterative process can be used to improve the I/Q correction factors. Using simple signal processing to measure the phase shift during calibration and to perform the image calibration calculations, the phase shifter requirements can be significantly relaxed, resulting in faster design time and reduced design area/cost. This approach results in reduced calibration time, thus contributing to reduced factory production time and enabling faster live mode image calibration.

  • Patent number: 11382056
    Abstract: The present disclosure describes techniques and systems for location-based resource scheduling, to reduce or eliminate receiving transmissions, by the base station, over one or more communication resources allocated for another communication. In some aspects, a user device (102) establishes a wireless connection (106) with a base station (104). The user device (102) receives, from the base station (104), a propagation delay message (304). The propagation delay message (304) schedules a delay for a transmission of the user device (102). The delay is based on a location of the user device (1020) being outside of a standard distance (614) from the base station (104). The user device (102) then transmits, to the base station (104), the transmission according to the propagation delay message (304).

  • Patent number: 11356141
    Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

  • Patent number: 11334283
    Abstract: A method for providing application data of at least one application executable on a control unit of a vehicle. The control unit includes components for running an operating system including a virtual memory management. In the method, an application address space of a first virtual memory is initially read out, the application address space being assigned to a process of the application and representing an area of a physical memory of the control unit occupied by the application data. The application address space is mapped in a further step into a virtual address space, which is assigned to a process of a communication application for exchanging data via a communication interface to a control unit-external evaluation unit. The application data are therefore retrievable via the communication interface.

  • Patent number: 11336323
    Abstract: A front-end module includes: a switch module that performs CA for bands A and C and performs non-CA for band B, which is located between these two bands, and that has a common terminal and selection terminals; a duplexer that is connected to the selection terminal and allows band A to pass therethrough; a duplexer that is connected to the selection terminal and allows band C to pass therethrough; an impedance matching network that is connected to the selection terminal; and a reception filter that is connected to the impedance matching network and allows band B to pass therethrough. During CA for bands A and C, a first circuit, which includes the impedance matching network and the reception filter, forms an attenuation pole in the frequency band of band C in the transmission characteristic of a path connecting the duplexer, the common terminal, and the duplexer to each other.
