Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to select a set of beams to generate energy in a first coverage region (e.g., an out-of-coverage (OOC) region) to reduce the effects of a distorted electric field. The UE may select the set of beams based on gain parameters associated with a set of antennas at the UE, where the gain parameters are determined for communications in a second coverage region (e.g., an in-coverage (INC) region). In some examples, the UE may use iterative techniques to select the beams. In some examples, the UE may select the set of beams based on calculations using a set of codebook beams associated with the second coverage region. In some examples, the UE may additionally select the set of beams for communications in the second coverage region.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to detect motion of the UE based on a motion sensor, such as an inertial measurement unit (IMU). The UE, based on the detected motion, may trigger a measurement procedure in which measurements of different beams or cells are performed at a greater periodicity than if the motion were not detected. The indication from the motion sensor may indicate that UE acceleration, rotation, orientation, or any combinations thereof, exceeds a threshold and results in the UE switching to a fastest available measurement periodicity. After triggering the fastest available measurement periodicity, the UE may adjust the measurement periodicity based on newly obtained beam measurements and converge to a measurement periodicity based on observed metrics.
