20230021575 · 2023-01-26 ·

Disclosed are systems and methods for entities in a 5G or 6G wireless network to indicate their geographical location to other entities. A base station can inform the user devices of its antenna location so that the users can direct beams toward the antenna. Mobile users can update their location information to the base station so that the base station can direct beams toward the mobile users in real-time. For example, the base station can embed the latitude and longitude of the base station antenna in a system information message, such as an unallocated portion of the SSB (synchronization signal block) which is periodically broadcast, and the users can transmit location-update messages to the base station using disclosed formats. By directing transmission beams and reception beams toward each other, base stations and users can obtain substantially improved reception with reduced background generation and reduced energy consumption.

Automatic adjustment of transmission power for 5G/6G messaging
11533084 · 2022-12-20 · ·

Automatic adjustment of the transmission power, of 5G and 6G wireless messages, is necessary for efficient energy utilization and minimizing background generation, especially in high-density communication environments. However, the power level needed for adequate reception is a complex compromise among competing factors related to network performance, message features, and constantly changing noise/interference backgrounds. Disclosed are artificial intelligence systems and methods configured to determine an appropriate power level for communications. The AI model is trained to account for a wide range of conditions in real-time. For field use, an algorithm derived from the AI model, may be simplified and reduced in size to be appropriate for mobile user devices. The base station may prepare a map of signal attenuation factors, noting especially the “dead zones” of poor reception, and increase the transmission power whenever a mobile user device enters such a location. Many other aspects are disclosed.

Location-Based System Information and Doppler Correction in 5G/6G
20220337290 · 2022-10-20 ·

A base station of a 5G/6G network can include its location coordinates in the SSB system information message which is broadcast on a standard frequency periodically. A mobile user device can receive the SSB and thereby determine the base station location. Thereafter, the user device can measure its own location, speed, and direction of travel, and thereby calculate a Doppler frequency correction before transmitting a message to the base station, thus causing the base station to receive the message at the expected standard frequency. In addition, the user device can calculate, based on the location of the base station relative to the direction of travel of the mobile user device, a particular frequency at which downlink messages from the base station will be received. In addition, the user device can pre-emptively adjust its transmission frequency when changing speed or direction, thereby avoiding wasteful frequency-correction messages from the base station.
