Abstract: Various communication devices may benefit from the appropriate use of modeling techniques. For example, devices that include components that may be driven into non-linear ranges of operation may benefit from low complexity non-linear modelling techniques. Such devices may be used, for example, in wireless communication systems. A method can include obtaining a sample of a signal representative of power consumed by a device while the device is operating in a non-linear range while being driven according to a driving signal. The method can also include computing a correction to the driving signal based on the sample. The correction can be calculated based on a plurality of non-overlapped non-linear sections corresponding to a response of the device. The method can further include applying the correction to adjust the driving signal. The correction can be configured to adjust the power to a desired value of power.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

The base station may transmit a beam tapering configuration of the one or more beam tapering configurations to the first wireless node, and the first wireless node may transmit a beamformed message to the base station according to the beam tapering configuration. In some cases, the beam tapering configuration may be associated with less interference when transmitting the beamformed message.

Abstract: A method and apparatus for beamspace processing in a radio access node are proposed. A channel estimate, which characterizes a radio channel between the antenna elements of an antenna array and a user equipment for a given time and a given frequency, is transformed using multiple distinct sets of spatial orthonormal basis functions to obtain transformed channel estimates.

Data streams are encoded, based on a selected transformed channel estimate, into encoded data streams. The encoded data streams are then transmitted through the antenna elements of the antenna array.
