Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive a set of reference signals having different levels of power amplifier compression. The mobile station may transmit a measurement report based at least in part on measurements of the set of reference signals. Numerous other aspects are described.

A method for configuring telemetry transmission includes receiving a transmitted telemetry signal at the earth's surface. The received signal is selected and processed to compute a measured power spectral density (PSD). A theoretical PSD is computed of the transmitted signal at the known carrier frequency and processed in combination with the measured PSD to compute an attenuation factor of the transmitted signal at a plurality of frequencies.

An electronic device includes a network monitor configured to acquire network environment information related to a radio frequency (RF) transmission signal; a transceiver configured to generate an envelope signal of the RF transmission signal; a transmission (Tx) module including a power amplifier for receiving the RF transmission signal from the transceiver and amplifying the RF transmission signal; and an envelope tracking (ET) modulator configured to receive the envelope signal from the transceiver and to provide a bias of a power amplifier to correspond to the envelope signal, wherein the ET modulator determines a magnitude of the bias of the power amplifier based on the network environment information acquired by the network monitor.

A method and network node for timing error estimation and compensation for Fifth Generation (5G) New Radio (NR) downlink (DL) systems with uncalibrated antennas are provided. According to one aspect, a method in a network node includes transmitting a first Channel State Information Reference Signal (CSI-RS) having a first timing compensation and transmitting a second CSI-RS having a second timing compensation, receiving a CSI-RS resource indicator (CRI) in a CSI report from a wireless device (WD), and determining from the CRI which of the first and second timing compensation results in a greater spectrum efficiency.

Methods and devices are provided to enable a cooperating group of user equipments (UEs) to receive a group-specific common-parameters configuration (CPC) message over a first spectrum band and access a second spectrum band synchronously for device-to-device (D2D) sidelink transmission within the group. In an embodiment, a UE operating in a cooperation mode in a cooperating group of UEs receives a group-specific common-parameters configuration (CPC) message from a transmit point (TP) over a first spectrum band, the group-specific CPC message comprising information to configure cooperating UEs in the group for synchronous clear channel assessment (CCA) and aligned sidelink transmission starting times in a second spectrum band. The UE performs a synchronous CCA in the second spectrum band in accordance with a common contention window generated based on the information in the group-specific CPC message.

Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may operate in accordance with a full-duplex communication mode and may be scheduled for an uplink transmission without a simultaneous downlink reception. For example, the UE may actively operate both a first one or more antenna panels for transmission and a second one or more antenna panels for reception and, in scenarios in which the UE is performing an uplink transmission without simultaneously receiving a downlink transmission, the UE may use self-interference from the uplink transmission at the second one or more antenna panels for energy harvesting. For example, the UE may receive the self-interference associated with the uplink transmission at the second one or more antenna panels, may refrain from applying interference cancellation, and may instead use a received energy from the self-interference to power one or more components of the UE.

Downhole telemetry systems and related methods adaptively compensate for channel non-linearity effects. To compensate for channel non-linearity, the optimum signal generation parameters are determined that produce the desired modulated pressure variation at the surface. The signal generation parameters are optimized to minimize the discrepancy between the surface detected pressure signal and the intended signal. The mud propagation channel is first estimated in light of the known modulation scheme under an ideal linear-time-invariant channel assumption. The estimated channel is used to synthesize the modulated pressure signal undergoing the mud propagation given the initial signal generation parameters. The method then varies the synthesized signal generation parameters to search for the optimal signal generation parameters. The optimal signal generation parameters are then sent over downlink channel to the downhole pulser, which is ultimately used to generate the pulse waveform.

A method is performed by a coordinating controller of a site that includes the at least two radio signal paths. The method includes obtaining, from a respective inner controller of each of the at least two radio signal paths, long-term 5 time averaged traffic related information for each of the at least two radio signal paths. The method includes determining control information for each of the at least two radio signal paths based on the long-term time averaged traffic related information, antenna gain information for each of the at least two radio signal paths, and a condition on total average EIRP for the site, and performing 10 individual average EIRP control of each of the at least two radio signal paths by providing the control information to each respective inner controller.
