Patent ID: 11411612

Abstract:
In 5G/6G wireless networks, a user device and a base station may transmit and receive messages unidirectionally, using directional antennas, and may thereby provide sufficient reception while saving energy and time. A user device can determine its own location and the location of the base station, calculate an angle toward the base station, and thereby transmit a narrow-beam message to the base station. The message may indicate the user device's location so that the base station can direct its transmission and reception beam toward the user device. The user device and the base station can then transmit and receive messages unidirectionally for improved energy efficiency, improved reception, and reduced interference generation. In addition, a mobile user device can indicate its speed and direction of travel, so that the base station or other user devices can calculate the changing angle and direction toward the other, and may thereby redirect their transmission and reception beams toward the other, without the need for frequent location messages or beam scanning.
