One disclosure of the present specification provides a method for performing communication by a user equipment (UE). The method comprises the steps of: receiving a downlink signal, wherein the downlink signal is received with channel bandwidth of 400 MHz, wherein the downlink signal is received via n263 frequency band, wherein the UE is power class 3 UE, wherein the transceiver is configured to satisfy a Radio Frequency (RF) requirement, wherein the RF requirement includes at least one of REFSENS (Reference Sensitivity) and EIS (Effective Isotropic Sensitivity) spherical coverage.

There is provided a communication device comprising: a control unit configured to control ranging with a wireless signal in conformity with a regulated communication standard, wherein the control unit controls output intensity of a data transmission signal that has a payload based on reception sensitivity for a plurality of ranging signals transmitted to and received from other communication devices.

A method for measuring a sensitivity of a receiver is provided. The method includes: during a first stage, controlling a signal generator to transmit an input test signal to an input node of the receiver, wherein the receiver generates an output test signal on a first output node of the receiver according to the input test signal; calculating a path loss from the input node of the receiver to the first output node of the receiver according to the input test signal and the output test signal; during a second stage, measuring an output noise power on a second output node of the receiver after a load is connected to the input node of the receiver; and calculating the sensitivity of the receiver according to the path loss and the output noise power. The load may be an antenna or a 50-ohm impedance load.

Embodiments disclosed herein relate to techniques for determining a maximum sensitivity degradation (MSD) value at a user equipment (UE), and sending the value to a network for scheduling a frequency band combination for uplink and/or downlink communication. The network configures the frequency band combination for the UE, and determines whether there may be potential interference when the UE uses the frequency band combination. If so, then the network sends an indication to the UE to deactivate uplink transmission. The UE then determines reference sensitivity (REFSENS) of its receiver when the network does not send a downlink transmission on the frequency band combination. The UE sets its transmitter to transmit with a predetermined (e.g., maximum) transmission power, sends uplink transmissions, and determines an interference power when operating using the frequency band combination. The UE then determines the MSD value based on the REFSENS and the interference power.

Disclosed are an OTA test method for a vehicle antenna system, a device and a storage medium. According to the method, the radio frequency performance of a physical layer of a whole vehicle antenna system can be tested, and the problem in the prior art that the test result of parts cannot accurately reflect the performance of the whole vehicle antenna system can be solved.

A sensing method includes: implementing, at a UE, a sensitivity time control profile to change a gain applied over time to a sensing signal received by the UE; and measuring the sensing signal to obtain a sensing signal measurement; wherein the method comprises at least one of: obtaining the sensitivity time control profile based on a sensitivity time control message received by the UE from a network entity; or transmitting a sensing report from the UE to the network entity, the sensing report indicating a measurement of the sensing signal and that sensitivity time control was implemented to obtain the sensing signal measurement.

A method for controlling interference is performed by a terminal device, and includes: transmitting first indication information, wherein the first indication information indicates interference information of the terminal device.

A system for vehicle motion control (VMC) performance enhancement utilizing real-time data reliability and criticality assessments includes a vehicle having sensors and actuators. The sensors collect real-time dynamic state information about the vehicle. The actuators actively and continuously adjust the dynamic state of the vehicle. The system executes a VMC application that obtains, from the sensors and actuators, dynamic state information of the vehicle, and estimates a real-time vehicle dynamic state from the dynamic state information. The VMC application determines a signal criticality and a signal reliability for vehicle dynamic state information, and executes a VMC strategy based on the real-time vehicle dynamic state, the signal criticality and reliability. The VMC application detects and mitigates signal degradation by enacting a VMC strategy, and generates a VMC output command to the actuators based on the VMC strategy. The VMC strategy actively, continuously, and automatically adapts to seamlessly overcome signal degradation.

An apparatus can include communications circuitry configured to receive a signal. The signal can have encoded thereon a plurality of data packets in a sequence with interpacket time differentials. The apparatus can include processing circuitry coupled to the receiver circuitry and to two or more antennas. The processing circuitry can responsive to determining that the interpacket time differentials correlate with a set of expected interpacket time differentials, measure relative signal strength of the signal at the two or more antennas. The processing circuitry can also determine a position or a distance of a second apparatus relative to the apparatus based on a comparison of measured signal strength at the two or more antennas. Other systems and methods are described.

Various aspects of the present disclosure relate to a communication device (e.g., a user equipment (UE)) that has a transceiver and a set of antenna panels. The communication device transmits a signal from the transceiver, where the signal is transmitted simultaneously as a maximum power reference signal from a best beam in each antenna panel of the set of antenna panels for a measurement of effective isotropic radiated power (EIRP) in a transmission direction. Additionally, the communication device receives a reference signal, and demodulates the reference signal independently for each antenna panel of the set of antenna panels for a measurement of effective isotropic sensitivity (EIS) in a reception direction.
