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: 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.
