Abstract: Methods, systems, and devices for wireless communications are described for self-interference or cross-link interference measurements at a user equipment (UE). A UE may receive configuration information from a base station that indicates one or more slot format index (SFI) values that are compatible for cross-link interference or self-interference measurements. Based on the configured SFI(s), the UE may measure interference in multiple symbols, which may be used to estimate an amount of cross-link interference or self-interference, and the UE may transmit a measurement report to the base station. The base station, based on the measurement report, may identify one or more compatible SFIs, beam pairs, or combinations thereof, for subsequent communications with one or more UEs. The interference measurements may identify cross-link interference at the UE that results from transmissions of a different UE, or may identify self-interference of concurrent communications of multiple channels at a same UE.

Abstract: A transceiver is configured for a calibration mode of operation in which an impedance of a transmit chain is tuned responsive to a power measurement of a mixed RF calibration signal to form a tuned transmit chain. A direct conversion mixes an RF calibration signal with a DC offset signal to form the mixed calibration signal. During a normal mode of operation, a heterodyne mixer mixes an LO signal with an IF signal to produce an RF signal that is amplified through the tuned transmit chain.

Abstract: An apparatus is disclosed for an antenna with a conductive cage. In an example aspect, the apparatus includes a ground plane with at least one opening. The apparatus also includes at least one antenna assembly with at least one radiating element, at least one feed via, and a conductive cage. The radiating element is implemented on a first plane that is substantially parallel to the ground plane. The feed via is connected to the at least one radiating element and is configured to connect to at least one transmission line through the opening. The conductive cage includes at least three ground vias, which are connected to the ground plane at positions that are distributed around the opening. Lengths of the at least three ground vias extend a portion of a distance between the ground plane and the radiating element.

Abstract: An antenna system includes: a ground conductor; a substrate; a pair of planar dipole conductors disposed such that at least a portion of the substrate is disposed between the ground conductor and the pair of dipole conductors; a pair of energy couplers each electrically connected to a respective one of the pair of dipole conductors; and a pair of isolated lobes including electrically-conductive material. The pair of isolated lobes are electrically separate from the pair of dipole conductors and the pair of energy couplers, and disposed between the pair of dipole conductors and the ground conductor.

Abstract: Certain aspects of the present disclosure provide an N-path filter implemented using a generalized impedance converter (GIC) circuit. The GIC circuit is configured such that the N-path filter has a desired frequency response, which may include a wide passband with steeper rejection than a conventional N-path filter with only a single pole in each filter path. Certain aspects of the present disclosure provide an N-path filter having a frequency response with multiple concurrent passbands. In certain aspects, the N-path filter with multiple passbands is implemented using the GIC circuit. In other aspects, the N-path filter may include a bandpass response circuit where an inductance of the bandpass response circuit may be implemented using gyrators.
