Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may operate in accordance with a full-duplex communication mode and may be scheduled for an uplink transmission without a simultaneous downlink reception. For example, the UE may actively operate both a first one or more antenna panels for transmission and a second one or more antenna panels for reception and, in scenarios in which the UE is performing an uplink transmission without simultaneously receiving a downlink transmission, the UE may use self-interference from the uplink transmission at the second one or more antenna panels for energy harvesting. For example, the UE may receive the self-interference associated with the uplink transmission at the second one or more antenna panels, may refrain from applying interference cancellation, and may instead use a received energy from the self-interference to power one or more components of the UE.

Abstract: Currently, user devices in a 5G/6G wireless network must perform a complex iteration procedure to align their directional transmission/reception beams toward the base station. Disclosed is a faster, simpler procedure to enable users with beamforming capability to align their beams. The base station transmits a series of sequential signals, all with the same amplitude, modulation, and spatial distribution. A user device can receive the signals using directional reception beams oriented in various directions, measuring the signal quality for each of the reception beams. The user device can then select the reception beam with the best signal quality, or it can interpolate between the two best beams to determine the optimal alignment direction toward the base station. A single user device (such as a new arrival) can align its beam, or all of the user devices in the network can optimize their beams simultaneously, saving time at very low resource cost.

Abstract: Aspects described herein relate to determining one of multiple antenna panels to use to receive downlink beams based on whether a configuration from a base station indicates an antenna panel associated with the downlink beam or in determining a number of repetitions of a downlink beam to receive in beam refinement.

Abstract: In 5G and 6G, beam alignment remains an arduous, time-consuming process. Procedures are disclosed herein for rapid and efficient beam alignment, by configuring a phased-array antenna to emit a “triangular beam”, which is a wide beam that varies in angle from a high power at angle-1 to a low power at angle-2, with a ramp-like intensity variation in the region between the two angles. Then a second signal is emitted, with the triangular distribution reversed (higher power at angle-2). A receiver can then measure the as-received amplitudes from the two triangular beams, calculate the ratio of signal reception from the two beams, and thereby determine the alignment angle. In another version, the transmitter transmits two non-directional pulses, and the receiver detects them using a triangular sensitivity distribution versus angle. By either method, the devices can align their beams using just two triangle beam pulses, saving substantial time, resources, and background generation.

Abstract: Embodiments provide for guided alignment of the orientation of two wireless devices. A first wireless device is at a known position and a known orientation. A signal from a second wireless device is received via a plurality of receive elements of the first wireless device. The first wireless device measures phase differences of the signal at the plurality of receive elements, and determines locations of each of the second wireless device's transmit elements based on the differences. Based on the transmit element locations, and a known antenna layout of the second wireless device, an orientation of the second wireless device is determined. Based on differences between the determined orientation and the known orientation of the first wireless device, instructions for aligning the devices are generated. Once the devices are aligned, location estimates of a third wireless device are made by both the first wireless device and the second wireless device.

Abstract: Various communication devices may benefit from the appropriate use of modeling techniques.

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).
