AI Technical Summary

Technical Problem

In 5G radio access technology, it is difficult for the prior art to efficiently perform beam prediction, especially when angle assist information is used at user equipment, resulting in large measurement overhead and low prediction accuracy.

Method used

By receiving auxiliary information at the user equipment and measuring multiple reference signal transmissions from the network, the model is used to predict the optimal beam or reference signal reception power and report the prediction results to the network. The auxiliary information includes the angle of the user equipment position relative to the base station panel array to reduce the necessary number of RSRP measurements.

Benefits of technology

It realizes reducing beam measurement overhead in 5G radio access technology, while improving the accuracy and efficiency of beam prediction, and reducing the interference level in the system.

Abstract

Systems, methods, apparatuses, and computer program products for beam prediction using angle assistance information by a user equipment are provided. For example, a method may include receiving assistance information from a network and measuring a plurality of reference signal transmissions from the network. The method may also include predicting, at the user equipment, an optimal beam or reference signal received power using the model. Measurements of the auxiliary information and the plurality of reference signal transmissions are input to the model. Reporting the predicted optimal beam or reference signal received power to the network may also be performed.
