Abstract: Techniques for generating a power tracking supply voltage for a circuit (e.g., a power amplifier) are disclosed. The circuit may process multiple transmit signals being sent simultaneously on multiple carriers at different frequencies. In one exemplary design, an apparatus includes a power tracker and a power supply generator. The power tracker determines a power tracking signal based on inphase (I) and quadrature (Q) components of a plurality of transmit signals being sent simultaneously. The power supply generator generates a power supply voltage based on the power tracking signal. The apparatus may further include a power amplifier (PA) that amplifies a modulated radio frequency (RF) signal based on the power supply voltage and provides an output RF signal.

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 and the at least one receive chain. 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: A method and apparatus for reducing distortion of satellite signals modulated using amplitude phase shift keying (APSK) are disclosed. A receiver such as a user terminal receives, from a satellite, a signal including APSK-modulated symbols mapped to a constellation including a plurality of points arranged in an inner circle and in an outer circle; determines, based on the received APSK-modulated symbols, a ratio between a radius of the inner circle of the constellation and a radius of the outer circle of the constellation; generates a correction signal based, at least in part, on a comparison between the determined ratio and a reference ratio; compensates for distortion of the received signal based, at least in part, on the correction signal; mixes the correction signal with the received signal to generate a distortion-compensated signal; and de-modulates the distortion-compensated signal to recover data transmitted from the satellite.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may indicate a dynamic beam correspondence operation for communications with a second device. For example, the dynamic beam correspondence operation may be declared in a time-dependent manner, for certain transmission configuration indication (TCI) states, time-dependent TCI states, etc. Additionally or alternatively, the first device may declare no beam correspondence and associated power savings and thermal reductions that result from the lack of beam correspondence. Subsequently, based on the dynamic beam correspondence operation, the second device may identify parameters (e.g., which TCI states, subarrays, etc.) for the first device to use for different modes or procedures (e.g., at a corresponding time) based on parameters that correspond to a full beam correspondence or no beam correspondence. For example, the parameters may be used for initial access, beam failure recovery, low power modes, high temperature modes, etc.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal from a network entity, the configuration signal indicating a configuration for a first positioning reference signal. The UE may determine one or more properties associated with the first positioning reference signal based on the configuration signal. The UE may bypass at least one portion of a transmit chain associated with a scheduled transmission of the first positioning reference signal or a receive chain associated with a scheduled reception of a second positioning reference signal. The UE may then activate, after an end of the transmission or the reception, the at least one portion of the transmit chain associated with the scheduled transmission of the first positioning reference signal or the receive chain associated with a scheduled reception of the second positioning reference signal.

Abstract: Phase variations between a transmitter (TX) waveform and a receiver (RX) waveform produced by a TX Phase-Locked-Loop (PLL) and a RX PLL, respectively, is a source of error in processing delay calibration used, e.g., in Round Trip Time (RTT) estimation. While a TX waveform and a RX waveform have a constant phase delay while in steady state conditions, during transient times, e.g., at start up or reset, the phase delay may vary by as much as 180, which at baseband frequencies of 50 MHz, introduces a random delay variations of as much as 10 nsec, which is undesirable for fine position estimation using RTT. The phase delay variation between the TX waveform and RX waveform may be reduced or eliminated using a phase correction signal generated using the output signals of the TX PLL and RX PLL.

Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Precharacterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of a range of frequencies outside an operational bandwidth of the UE based at least in part on the range of frequencies being compatible with one or more sets of analog beamforming beam weights associated with the operational bandwidth. The UE may communicate, with the base station, based at least in part on transmitting the indication of the range of frequencies outside of the operational bandwidth of the UE. Numerous other aspects are provided.
