A wireless communication network such as a 5G communication network can use MIMO technologies to enhance bandwidth between a wireless communications base station and one or more user equipment devices within a service area of the base station. RF signal repeaters can be utilized to provide one or more additional physical channels for communication between the MIMO base station and the MIMO user equipment. These RF signal repeaters can be regarded as increasing the MIMO channel diversity within the ambient environment.

Physical layer processing methods for network acquisition by remote nodes in wireless communication systems are described herein. New methods for wireless network discovery and synchronization by remote nodes are described herein that utilize spatial (e.g., antenna array) processing algorithms which may achieve enhanced functioning in challenging radio frequency environments, such as those containing interference and multipath distortion effects. These methods may include advantageous use of spatial whiteners and associated pluralities of adaptive beamformers to detect network reference and synchronization signals and estimate their parameters.

An information processing method and apparatus, a terminal, and a communications device are provided. The method includes: determining, based on detection of a reporting trigger event, whether to report an event-based beam report and/or an event-based channel state information (CSI) report to a network-side device.

The disclosed invention provides a distributed directional aperture (DDA) system that is installed in a vertical lift aircraft that comprises a fuselage and a rotor system including rotary wings rotatably coupled to the fuselage. The DDA system provides capability to receive and/or transmit signals in one or more frequency bands, and provides communications, signals intelligence (SIGNINT), positional sensing, jamming, and offensive cyber on the vertical lift aircraft. The DDA system of the vertical lift aircraft includes a sensor and emitter array subsystem that includes a plurality of sensors and emitters distributed in the rotary wings, a beamformer subsystem that processes the sensor signals and emitter signals, and a telemetry subsystem that conveys signals between the sensor and emitter array subsystem and the beamformer subsystem.

The present solution ensures that the UEs are able to make use of all the available reference signals that can be used in a cell for performing UE measurements, estimations or demodulations. That is achieved by indicating on a downlink common or shared channel, the MIMO mode settings associated with a specific network node. The indicated MIMO mode settings explicitly or implicitly indicate available common reference signals and/or dedicated reference signals to be used for said UE measurements, estimations or demodulations, which implies that measurements, estimations or demodulations can be performed based on said received indication.

Methods and systems are provided for dynamically detecting and correcting the deactivation of beamforming from an antenna. One or more users are identified as present within a particular geographic area typically served by beamforming, and the average signal strength of the one or more user devices is monitored. If a threshold level of degradation of the average signal strength is detected, then a beamforming status is determined for one or more of the antennas serving the user device or devices. Based on the determination, corrective measures are taken and beamforming is reactivated.
