Abstract: Aspects of the disclosure relate to an apparatus (e.g., a user equipment (UE)) configured to operate in a full-duplex mode. The apparatus may include at least one transmit chain configured to operate within a first frequency band and at least one receive chain configured to operate within a second frequency band. The apparatus may receive coordination information that is configured to mitigate the self-interference between the at least one transmit chain of the apparatus and the at least one receive chain of the apparatus. In some examples, the received coordination information includes at least one of subcarrier spacing coordination information, beam coordination information, or slot format index coordination information. In some examples, the apparatus may transmit a first signal while receiving a second signal based on at least the subcarrier spacing coordination information, the beam coordination information, or the slot format index coordination information to mitigate self-interference.

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: An apparatus is disclosed for implementing a flexible beamforming architecture. In an example aspect, the apparatus comprises an antenna array comprising a first antenna element with a first feed port and a second antenna element with a second feed port. The apparatus also comprises a wireless transceiver with a first dedicated transceiver path coupled to the first feed port and a second dedicated transceiver path coupled to the second feed port. The wireless transceiver also comprises a flexible beamforming network configured to selectively be in a first configuration that couples both the first dedicated transceiver path and the second dedicated transceiver path to a first intermediate transceiver path of the wireless transceiver, and be in a second configuration that connects the first dedicated transceiver path to the first intermediate transceiver path and connects the second dedicated transceiver path to a second intermediate transceiver path of the wireless transceiver.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine at least one of an orthogonal frequency division multiplexing (OFDM) parameter associated with the UE or a modem function associated with a modem of the UE. The UE may control a loop bandwidth of a phase-locked loop (PLL), used to generate a tunable radio frequency (RF) carrier frequency used by the UE to communicate synchronously with a base station, based at least in part on at least one of the OFDM parameter or the modem function. Numerous other aspects are provided.

Abstract: In certain aspects, a method for calibration includes setting a phase shift of a first phase shifter to a reference phase shift, wherein the first phase shifter shifts a phase of a first signal transmitted via a first antenna. The method also includes sequentially setting a phase shift of a second phase shifter to each one of a first plurality of phase shifts, wherein the second phase shifter shifts a phase of a second signal transmitted via a second antenna. The method further includes receiving the first and second signals at a receiver via a third antenna, and, for each one of the first plurality of phase shifts, measuring a magnitude of a third signal at the receiver, wherein the third signal includes the received first and second signals. The method further includes determining a calibration phase shift based on one or more of the measured magnitudes.
