Deterministic low-complexity beam alignment for 5G and 6G users

Abstract

5G and especially 6G are built around beamed transmissions and receptions, but aligning the beams toward the intended recipient is currently an expensive and complex process that reduced-capability devices may have difficulty performing. Therefore, an improved beam alignment process is disclosed, involving “triangle” beams. A triangle beam is a wide transmission beam that is arranged to be high-power at one side and low-power at the other side, tapering monotonically between the two angles. A user device can detect the triangle beam and measure the received amplitude or power level. By comparing to the amplitude of a previous transmission, the user device can determine its angle relative to the base station. The user device can then transmit directional beams toward the base station, and can also inform the base station of the angle so that they both can use well-directed transmission and reception beams. Many other aspects are disclosed.
