Method and apparatus for providing enhanced reference signal received power estimation
A method and an apparatus for providing reference signal received power (RSRP) are disclosed herein. A signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements at the RS locations are descrambled. Virtual reference signal (VRS) elements are formed using the descrambled signal elements. The VRS elements have smaller noise variances than original RS elements in corresponding locations of the received signal. The RSRP is estimated from the VRS elements.

VEHICLE CONTROL APPARATUS
A vehicle control apparatus comprises a radio receiver and a control unit. The radio receiver receives a terminal signal from a first terminal that a user located outside the vehicle carry. The control unit performs a remote operation control to move the vehicle in accordance with a remote operation to the first terminal. The control unit is configured to: perform the remote operation control in accordance with the remote operation, when a signal condition including a condition that the terminal signal is received is satisfied; and in a case in which the signal condition becomes unsatisfied while performing the remote operation control, continue performing the remote operation control when an unsatisfied state in which the signal condition is not satisfied has not yet continued for a predetermined extension time, and stop performing the remote operation control when the unsatisfied state has continued for the extension time.
NARROW BEAM-BASED CHANNEL ACCESS
A method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, for each of a plurality of locations within a first zone, a first signal measurement for the one or more received signals, determining, at each of a plurality of locations within a second zone, a second signal measurement for the one or more received signals, wherein the second zone is different from the first zone, and determining whether the second wireless communication device satisfies an interference condition based at least in part on a cumulative distribution of at least one of the first signal measurements at the plurality of locations within the first zone or a cumulative distribution of at least one of the second signal measurements at the plurality of locations within the second zone.

Interference mitigation through SINR-based iterative distributed beam selection
Systems and methods for iterative distributed beam selection include a device including at least one of a first head wearable display (HWD), a second HWD, a first console or a second console. The device detects a predefined condition. The device performs a first distributed beam selection responsive to detecting the predefined condition. Performing the first distributed beam selection includes performing beamforming to provide a first plurality of beams for a first link between the first HWD and the first console, selecting a first beam of the first link with a highest signal-to-interference-plus-noise ratio (SINR) from the first plurality of beams, performing beamforming to provide a second plurality of beams for a second link between the second HWD and the second console while the first beam of the first link is active, and selecting a second beam of the second link with a highest SINR from the second plurality of beams.
IN-SERVICE FADE MARGIN MEASUREMENT
Methods may include alerting fixed service microwave operators that their network has been compromised due to interference, before their service is necessarily impacted. In an example, method may include receiving instructions to test fade margin for a wireless communication link associated with a receiver radio, wherein the wireless communication link is passing live traffic; testing the fade margin while the wireless communication link is passing the live traffic; receiving error information, wherein the error information is based on an error correction mechanism for the wireless communication link; based on the error information, determining that a threshold number of errors has been reached; and sending an alert based on the threshold number of errors.
