Title:
DEVICE, METHOD AND COMPUTER READABLE MEDIUM FOR ADJUSTING BEAMFORMING PROFILES
Document Type and Number:
WIPO Patent Application WO/2020/181533
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to an electric device, a method for adjusting beamforming profiles and computer readable medium. The electric device comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the electric device to: obtain performance measurement information for a broadcast area where an initial beamforming profile is currently used, the initial beamforming profile being determined from a set of candidate beamforming profiles; determine, based on the performance measurement information, the initial beamforming profile, each candidate beamforming profile in the set and a learning model, a respective beamforming performance estimation in case where a respective candidate beamforming profile is used in the broadcast area, wherein the learning model specifies an association between historical measurement information for the broadcast area and beamforming performance; and select one candidate beamforming profile from the set for the broadcast area based on the beamforming performance estimation and the performance measurement information such that an optimal beamforming performance can be obtained by using the selected candidate beamforming profile.
