Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station, control signaling identifying a measurement configuration for one or more non-linear estimation measurements of reference signals associated with a power amplifier configuration of the base station, receiving, from the base station, the reference signals on a set of resources identified by the measurement configuration, performing one or more non-linear estimation measurements associated with the power amplifier configuration of the base station based on the received reference signals, and transmitting, to the base station according to the measurement configuration, a measurement report based on the one or more non-linear estimation measurements.

The embodiments of the present application provide an indoor positioning system, including an information source module, a gateway, a first leaky cable and a first positioning device; where the information source module is connected to a first end of the first leaky cable through a feeder; the first positioning device is arranged between the first end of the first leaky cable and the feeder, and the first positioning device is configured to transmit a positioning signal through the first leaky cable, so as to enable the terminal to perform positioning according to the positioning signal. There is no need to set up a new positioning system, thus reducing costs for network construction as well as space requirements for the network construction.

This disclosure provides techniques for impedance matching. A radio frequency (RF) device includes a power detector to determine a transmitter leakage and a post-processing unit to determine a receiver leakage, and determines if isolation is acceptable based on the leakages. The RF device may include a device for measuring antenna impedance. Otherwise, the RF device may select multiple tuner settings (e.g., capacitor values) for test signals to be transmitted and received at a target frequency, determine multiple sets of leakage values, determine multiple reflection coefficients based on the multiple sets of leakage values, and determine an estimated antenna impedance at the target frequency based on the reflection coefficients. The RF device then determines impedance tuner settings based on the measured or estimated antenna impedance. Alternatively, the RF device determines impedance tuner settings using an inverse machine-learning model based on a determined matching impedance.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

An apparatus and a method for providing measurement information are provided. The method for providing measurement information of a user equipment (UE) includes measuring an uplink duty cycle percentage within a measurement duration, wherein the measurement duration is one of a configuration duration form a network node, a default duration, and a pre-defined duration, and reporting a maximum uplink duty cycle percentage according to a measured uplink duty cycle percentage within the measurement duration.

An operation system including: a prediction unit configured to determine a predicted value of a motion of an operator at a prediction time that is a time after elapse of a prediction time interval from the present using a predetermined machine learning model from a biomedical signal of the operator; a control unit configured to control a motion of a robot on the basis of the predicted value; and a prediction time setting unit configured to determine the prediction time interval on the basis of a delay time from a current value of the motion of the operator to the motion of the robot.

32 The present disclosure proposes schemes, techniques, designs and methods pertaining to frequency synchronization for integration of terrestrial network (TN) and non-terrestrial network (NTN) communications. Communications between a user equipment (UE) and a terrestrial network (TN) and communications between the UE and a non-terrestrial network (NTN) are established. A frequency shift in the communications between the UE and the NTN is compensated regardless of availability of information related to a movement of the UE and a relative location of the NT network node of the NTN with respect to the UE.

Certain aspects of the present disclosure provide techniques for beam refinement procedures including dynamic signaling and/or selection of beam-switching latency for beam refinement procedures using inter- and/or intra-antenna module beam switching. A method by a base station (BS) includes configuring a user equipment (UE) with one or more reference signal (RS) resource sets. Each of the one or more RS resource sets is associated with a first or second type of beam refinement procedure. The BS receives an indication from the UE of at least a first latency and a second latency, longer than the first latency. The BS dynamically selects, for each RS transmission using one of the configured resource sets, the first or second latency. The BS sends the RS transmissions at the selected latency with respect to downlink control information (DCI) triggering the RS transmissions for the first or second type of beam refinement procedure.

Cell acquisition is disclosed in frequency diversity configured for frame based equipment (FBE) access, such as using opportunistic frequency switching. A user equipment (UE) begins cell acquisition by synchronizing to an available communication channel of an available cell in response to detection of a synchronization signal block (SSB) associated with a network on which the UE communicates. The UE receives system information associated with the available cell from a serving base station, wherein the system information includes identification of at least: a link indicator identifying linked communication channels available for opportunistic switching, sensing occasion offsets for each of the linked channels, and access information associated with each of the linked channels. The UE measures a channel quality for each available channel. The base station transmits this system information on each of the linked channels and then monitors the allocated random access resources for signals from the UEs.

Embodiments of this application disclose an information transmission method. The method in embodiments of this application includes: A core network device receives indication information and delay information, and the core network device may determine, based on the indication information, whether the delay information includes a terminal side delay or whether the terminal device supports measurement of the terminal side delay.
