Abstract: Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.

Abstract: Systems and methods for providing indications about the TX RF non-linear impairments are disclosed. In accordance with some implementations, a first device (UE or base station) estimates EVM indications for the signal and determines if the EVM indications is above a threshold. The first device may transmit the estimated TX non-linearity indications such as AM-AM, AM-PM, Volterra coefficients, and/or other performance metrics to a second device, that transmitted the signal, when it is determined that the EVM indications is above the threshold. Systems and methods for wireless communication impairment correction are also disclosed wherein, in accordance with some implementations, a first device receives estimated TX non-linearity indications such as AM-AM, AM-PM, and/or Volterra coefficients from a second device and performs non-linear correction of a transmit signal for the second receiver device based at least in part on the EVM indications. Other aspects, embodiments, and features are also claimed and described.

Abstract: A user equipment (UE) includes a transmit chain that includes multiple radio frequency transmitters, multiple power amplifiers and a front end (FE) through which signals are transmitted. To achieve a high power UE solution, aspects of the disclosure selectively combine two or more power amplifier outputs based on an expected power output of the UE. To synchronously combine the outputs, an output feedback signal from a feedback receiver is used to adjust a delay and a phase of one or more signals associated with the power amplifiers.

Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.

Abstract: A transmitter includes a delta-sigma modulator characterized by a noise transfer function having a multitude of zeroes positioned substantially near a frequency band of a receive signal. The transmitter further includes, in part, a multi-phase digital-to-analog (DAC) converter converting an output signal of the delta-sigma modulator to an analog signal. The DAC is characterized by a transfer function that passes the desired signal to its output and attenuates a multitude of images of the sampling clock signal. The transmitter transmits at a frequency defined by an odd multiple of a fraction of the sampling clock signal frequency. The DAC includes a number of stages each pair of which is associated with one of the images being attenuated. The delta-sigma modulator includes a multitude of stages each associated with a different one of the zeroes. Each stage of said delta-sigma modulator optionally receives three tap coefficients.
