  • Publication number: 20250070714
    Abstract: A tank circuit includes a tunable resonator subcircuit having an effective parallel resistance that varies with tuning of the tunable resonator subcircuit. The tank circuit further comprises a variable negative-resistance subcircuit coupled in parallel to the tunable resonator subcircuit, where the variable negative-resistance subcircuit is configured to provide a variable negative resistance, so as to increase the effective parallel resistance of the tank circuit. A control circuit is configured to increase the negative resistance presented by the variable negative-resistance subcircuit in response to a change in the tunable resonator subcircuit that lowers the resonant frequency of the tunable resonator subcircuit.

  • Publication number: 20240356608
    Abstract: First processing circuitry of a first apparatus for compressing channel state information (CSI) classifies a CSI element into one of multiple classes of CSI elements. Each class is associated with a different one of multiple encoders. The first processing circuitry compresses the CSI element based on one of the multiple encoders associated with the one of the multiple classes of CSI elements, and sends, to a second apparatus, the compressed CSI element and a class index of the one of the multiple classes of CSI elements. Second processing circuitry of the second apparatus for decompressing CSI receives the compressed CSI element and the class index. Each class of CSI elements is associated with a different one of multiple decoders. The second processing circuitry determines one of the multiple decoders based on the class index, and decompresses the CSI element based on the determined decoder to obtain a decompressed CSI element.

  • Publication number: 20240348306
    Abstract: Aspects of the disclosure provide a method, an apparatus, and a non-transitory computer-readable medium for compressing channel state information (CSI). Under the method, a CSI matrix is decomposed, at a first device, into a first vector including a plurality of significant numbers extracted from the CSI matrix. A second vector is generated by multiplying the first vector with a linear operator. A length of the second vector is less than a length of the first vector. The second vector is sent from the first device to a second device along with a number of the plurality of significant numbers in the first vector. The method is implemented in software instructions, and when processing circuitry of the apparatus executes the software instructions, the processing circuitry of the apparatus performs the method. The software instructions are stored in the non-transitory computer-readable medium.

    Abstract: Techniques pertaining to channeling state information (CSI) pre-processing are described. A user equipment (UE) that is in wireless communication with a base station node extracts eigenvectors (EVs) from CSI acquired by the UE. The UE generates pre-processed CSI for compression by a machine-learning (ML)-based encoder of the UE into CSI feedback for the base station node by at least performing one or more of a phase discontinuity compensation (PDC), a one-step polarization separation with re-ordering, or a two-step polarization separation that includes separation based on polarization type and separation by position on the EVs.
