Finding the optimal beam pair and update time in 5G systems operating at mmWave frequencies is time-intensive and resource-demanding. This intricate procedure calls for the proposal of more intelligent approaches. Therefore, this work proposes a machine
As conditions change (or as the user device moves), the beam parameter can be updated again upon each downlink transmission, thereby tracking the user device's preferred transmission value in realtime.
Hence, a dynamical surface is obtained by switching PIN diodes to change the phase distribution on the surface. To verify the concept, the metasurface antenna is fabricated and measured with different OAM beam states, which are in agreement with the full-wave simulations, properly. The designed ...

摘要: PURPOSE: To recognize the state of a finishing point more quickly, by scanning a laser beam wafer repeatedly along the first scanning path, detecting the part of the laser beam reflected from the wafer, and analyzing the reflected beam for determining the desirable parking spot.收藏...
The change in distance between gauges x and y gives the deformation on the sample while the change in distance between gauges x and z multiplied by the stiffness of the force sensing beams gives the force acting on the sample. expectation, beam-induced artifacts are much more pronounced at ...

The change in the UE 906's position or orientation relative to the communication environment may lead to degradation of the channel when using the first pair of Tx and Rx beams 1030 and 1040. Thus, based on the motion of the UE, selection of a new pair of beams may be desirable. ...
This rapid change may present a challenge for beam management. Aspects of the present disclosure present techniques that may help support, in the near-field, efficient and swift beam switches to select a new beam based on the distance between the gNB and the UE (unlike a far-field operation...
