The method comprises obtaining (500) a three-dimensional model of a given environment; obtaining (502) ray tracing calculations describing propagation of radio frequency signals in the given environment; locating (504) one or more devices in the given environment; determining (506) utilising ray tracing calculations the radio frequency signal properties of one or more devices communicating with the device under test; transmitting (508) control information to the radio frequency controller unit for updating the connections between one or more devices and a set of antenna elements to match with the determined properties; obtaining (510) information on the location and propagation environment of the one or more devices and updating (512) the radio frequency signal properties of the one or more devices if the location or propagation environment changes.

Channel predictive behavior and fault analysis may be provided. A forward time value may be determined comprising a time a forward signal takes to travel from a transmitter over a channel to the receiver. Next, a reflected time value may be determined comprising a time a reflected signal takes to travel to the receiver. The reflected signal may be associated with the forward signal. A discontinuity may then be determined to exist on the channel based on the forward time value and the reflected time value. The reflected signal may be caused by the discontinuity and a high impedance or low impedance at the transmitter present after the forward signal is sent.

A wireless communications system may support beamforming to transmit and receive signals. A device operating within the wireless communications system may transmit a request to measure a beamformed reference signal. The device may also transmit a beamforming configuration indicating one or more beamforming options for measuring the beamformed reference signal. The beamforming options may include measuring the beamformed reference signal using a directional configuration and an omni-directional configuration. The device receiving the beamforming configuration may form a receive beam in accordance with the beamforming configuration to measure the beamformed reference signal. A device operating within the wireless communications system may determine to use a particular beamforming option for measuring a beamformed reference signal without first receiving a beamforming configuration, and may make the determination based on signal quality at the device or capabilities of the device.
