Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit information associated with one or more uplink transmissions performed by the UE within an L-band. The UE may receive, after transmitting the information, an adjusted frequency domain resource allocation that indicates an adjusted frequency range to be used by the UE for performing one or more other uplink transmissions. Numerous other aspects are described.

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: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may transmit, to each receiver device of a plurality of receiver devices communicating with the transmitter device over a wideband channel using frequency division multiplexing, an indication of a bandwidth portion of the wideband channel to be used by the receiver device for performing measurements associated with a non-linear model of the transmitter device. The transmitter device may transmit, to each receiver device of the plurality of receiver devices, one or more wideband reference signals associated with training the non-linear model. The transmitter device may receive a plurality of digital pre-distortion (DPD) coefficients, obtain a set of DPD coefficients based at least in part on combining the plurality of DPD coefficients, and perform DPD processing in accordance with the set of DPD coefficients. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transceiver chain may receive, using a downconverter tuned by at least one local oscillator, transmit signals that are modulated using a modulation bandwidth and that span a total bandwidth greater than or equal to the modulation bandwidth. The at least one local oscillator may cover a first fraction of the total bandwidth. The transceiver chain may receive, using at least one analog-to-digital converter, input from the downconverter, and may output a first digital signal based at least in part on the input and sampling at the first fraction of the total bandwidth. The transceiver chain may determine an error associated with the transmit signals based at least in part on the first digital signal, and may perform digital pre-distortion on new signals based at least in part on the error. Numerous other aspects are described.

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: A UE may identify one or more fractional bands in relation to a bandwidth associated with FD communication. Each fractional band in the one or more fractional bands may be a fraction of the bandwidth. The UE may sample at least one signal at the one or more fractional bands. The UE may estimate one or more SIC coefficients based on the at least one signal. The UE may perform SIC for the bandwidth associated with the FD communication based on the estimated one or more SIC coefficients. In one configuration, the at least one signal may be sampled with a sampling rate less than a threshold. In one configuration, the at least one signal may be sampled using an auxiliary hardware path including an auxiliary ADC. In one configuration, the sampling the at least one signal may be associated with decimation or rotation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit a first signal in accordance with a full duplex configuration. The network node may receive a second signal comprising a communication and self-interference associated with the first signal, wherein receiving the second signal comprises cancelling the self-interference based at least in part on a nonlinear interference cancellation (NLIC) procedure associated with a subset of kernels of a set of nonlinear candidate kernels corresponding to a nonlinear self-interference model.
