Abstract: Methods and apparatuses are disclosed for calculating and compensating for Doppler shift in a high-speed environment. When in a high-speed environment, Doppler shifts on a transmitted radio frequency signal can become extremely large, which may make it difficult or even impossible for a receiving device to accurately decipher the signal. Therefore, embodiments of the present disclosure describe how tracking reference signals can be transmitted from multiple transmission/reception points, and processed by the UE. For example, the TRS transmitted from the TRP can be enhanced to allow for TRS information from two different TRPs. Additionally, or alternatively, a flag can be set within TRS information that identifies it as having originated from either a first TRP or a second TRP. Additionally, the UE can calculate Doppler shift information and report that information back to the base station in a report message, such as an SRS message. In this manner, the base station can precompensate for the Doppler shift.

Abstract: 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.

Abstract: In 5G/6G wireless networks, user devices and base stations may adjust their transmission power according to the distance to the recipient, and thereby provide sufficient reception without wasting energy or generating interference. User devices can determine their own location by GPS, for example, and transmit that data to the base station so that the base station can adjust its downlink power accordingly. Likewise. base stations can transmit their location coordinates to user devices in, for example, a system information message. Sidelink, or V2V and V2X, messages can likewise be power-adjusted after user devices exchange their location coordinates. Mobile user devices can also indicate their speed and direction of travel, so that the base station or other user devices can calculate the changing distance and compensate power accordingly.

Abstract: Base stations and user devices can transmit 5G and 6G messages with a wide range of transmission power levels. Selecting the appropriate power level for each message is a complex problem, dependent on the distance to the recipient, the background noise and interference level, priority, and many other conflicting factors. To provide an objective recommendation of the transmitter power level, an artificial intelligence model may be trained, using actual network and message parameters, to accurately predict the subsequent network performance versus power level. Then, a practical algorithm may be derived from the trained AI model, and used by base stations and user devices to select an appropriate transmission power level according to current network conditions and message properties. Use of an appropriate transmission power level for each message may reduce message faults, enhance reliability, mitigate external noise and interference, and save energy especially for battery-operated user devices.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR).
