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 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.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting the transmission power of an unmanned aerial vehicle are disclosed. In one aspect, a method includes the actions of determining, by an unmanned aerial vehicle that includes a radio transceiver, an altitude of the unmanned aerial vehicle and a distance between the unmanned aerial vehicle and a base station. The actions further include, based on the altitude of the unmanned aerial vehicle and the distance between the unmanned aerial vehicle and the base station, determining, by an unmanned aerial vehicle, a transmission power level for the radio transceiver. The actions further include communicating, by the unmanned aerial vehicle, with the base station using the radio transceiver operating at the transmission power level.

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.

Systems and methods for an in-vehicle base station are described. In one embodiment, a mobile base station is disclosed comprising a first access radio for providing an access network inside and outside a vehicle; a second backhaul radio for providing a backhaul connection to a macro cell; and a global positioning system (GPS) module for determining a location of the mobile base station, and for transmitting the location of the mobile base station to a core network, wherein a transmit power of the first access radio is configured to increase or decrease based on a speed of the vehicle.

Disclosed are systems and methods in 5G and 6G, for compensating frequency shifts caused by the relative motion of a transmitter and receiver. For communication between a mobile user device and a base station, protocols can provide that the messages received by the base station comply with a predetermined channel frequency. Further protocols can provide that a mobile user device may transmit and receive messages at the same frequency. For sidelink communication, protocols can provide that peer devices can either transmit or receive at a predetermined channel frequency, greatly assisting reception of the messages.

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.
