DOPPLER-BASED BEAM TRAINING INTERVAL ADAPTATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18500475 titled 'DOPPLER-BASED BEAM TRAINING INTERVAL ADAPTATION

Simplified Explanation

The apparatus described in the patent application utilizes predicted Doppler spectrum information calculated using a radio-aware digital twin to adjust the beam refinement interval of a device in a propagation channel. This adjustment is based on measurements of reference signals and the removal of specific Doppler frequencies from the measured Doppler spectrum.

• The apparatus obtains predicted Doppler spectrum information for a propagation channel.
• The predicted Doppler spectrum information includes Doppler frequencies resulting from reflections from moving terminal devices.
• Measurements of reference signals are performed to form a channel estimate.
• A measured Doppler spectrum is calculated based on the channel estimate and specific Doppler frequencies are filtered out.
• The beam refinement interval of the device is adjusted based on the filtered measured Doppler spectrum.

Original Abstract Submitted

According to an aspect, there is provided an apparatus for performing the following. The apparatus obtains predicted Doppler spectrum information for a propagation channel between a first terminal device and one of an access node or a second terminal device calculated using a radio-aware digital twin. The predicted Doppler spectrum information includes information on one or more Doppler frequencies of a predicted Doppler spectrum resulting from reflections from one or more terminal devices capable of movement under control of the digital twin. The apparatus causes performing of measurements of one or more reference signals by a device associated with the propagation channel to a form a channel estimate. The apparatus calculates a measured Doppler spectrum based on the channel estimate and filters out the one or more Doppler frequencies from it. The apparatus adjusts a beam refinement interval of the device based on the filtered measured Doppler spectrum.
