  • Patent number: 11973707
    Abstract: Various schemes pertaining to distributed-tone resource unit (RU) operation in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes frequency tones of a resource unit (RU) over a distribution bandwidth as a distributed-tone RU (dRU). The communication entity then communicates using the distributed-tone RU in a 6 GHz low-power indoor (LPI) system. In some cases, the dRU is distributed over an entire bandwidth. Alternatively, the dRU operation is implemented per frequency segment. Alternatively, the dRU co-exists with regular or localized RU.

  • Publication number: 20240137054
    Abstract: Described herein are systems with switchable circuitry configured to selectively couple transmitter outputs to processing hardware, which may selectively route subsets of distortion measurements from transmitters for DPD processing that compensates for the measured distortion. The switchable nature of the distortion measurement propagation paths permits the paths to be made substantially shorter than static paths, resulting in improved (e.g., reduced and/or more uniform) attenuation and/or phase change across a transceiver array. In one example, measurement propagation paths may be no longer than a row or column of the array. In some embodiments, systems described herein may be suitable for implementation at mmW transmit and/or receive frequencies, where the length of measurement paths may have a significant impact on attenuation and phase changes.

  • Publication number: 20240137197
    Abstract: A push-start crystal oscillator (XO), an associated electronic device and a push-start method for performing a start-up procedure of an XO are provided. The push-start XO includes an inverting amplifier and a push-start logic control circuit, wherein the inverting amplifier is coupled to a crystal load. The inverting amplifier generates a first XO signal and a second XO signal. The push-start logic control circuit receives a feedback clock from a phase locked loop (PLL), and generates a phase control clock according to the feedback clock, wherein a push phase and a settle phase are specified by the phase control clock. During the settle phase, the PLL calibrates a frequency of the feedback clock according to the second XO signal. During the push phase, the feedback clock is transmitted to the inverting amplifier in order to increase the amplitude of the first XO signal.
