  • Apparatus and a method for generating a radio frequency signal
    Patent number: 10454748
    Abstract: An apparatus for generating a radio frequency signal based on a symbol within a constellation diagram is provided. The constellation diagram is spanned by a first axis representing an in-phase component and an orthogonal second axis representing a quadrature component. The apparatus includes a processing unit configured to select one of a plurality of segments of the constellation diagram containing the symbol. The segment is delimited by two radially extending boundaries, wherein the two radially extending boundaries span an opening angle of the segment that is different from 90°. The processing unit is further configured to calculate a first coordinate of the symbol with respect to a third axis, and a second coordinate of the symbol with respect to a fourth axis. At least one of the third axis and the fourth axis coincides with one of the two radially extending boundaries.

  • Coverage enhancement and normal modes switching related optimization
    Patent number: 10454520
    Abstract: Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

  • Methods and systems relating to ultra wideband broadcasting
    Patent number: 10455494
    Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.

  • Reconfigurable and modular active repeater device
    Patent number: 10447379
    Abstract: An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.

  • Carrier frequency offset compensation circuit and process for a communications receiver
    Patent number: 10348539
    Abstract: A frequency demodulated signal includes a frequency modulation in time that is shifted by a DC level corresponding to a carrier frequency offset. A number of different frequency offsets are applied to the frequency demodulated signal to generate a corresponding number of offset frequency demodulated signals. Each offset frequency demodulated signal is correlated against a reference signal and a determination is made as to which correlation produces a highest correlation value. One offset frequency demodulated signal of the number of offset frequency demodulated signals is then selected for output as an offset corrected frequency demodulated signal. The selected signal is the one having the highest correlation value.
