Abstract
A method performed by a beam management system that obtains spatial and temporal measurements of a mobile terminal and geolocation information of an associated base station on a wireless communication network. The system determines a phase compensation value for the mobile terminal based on the obtained information, which is used to calculate or select coefficients for antenna elements that form an optimal antenna beam. Thus, the system can perform beam switching quickly and efficiently based on predicted spatial or temporal characteristics of the mobile terminal without needing to wait for actual beam measurements.

- obtaining spatial and temporal measurements of a mobile terminal connected to a base station of the wireless communication network;
- obtaining geolocation information of the base station;
- determining a phase compensation value for an antenna of the mobile terminal at a future time based on an expected rotation and geolocation of the mobile terminal,
- wherein the phase compensation value is based on the spatial and temporal measurements of the mobile terminal and the geolocation information of the base station;
- obtaining one or more coefficients for one or more antenna elements of the antenna to select an antenna beam for the future time based on the phase compensation value;
- and
- configuring the one or more antenna elements to form the antenna beam in a direction relative to the expected rotation and geolocation of the mobile terminal.
