Spatially Guided Beamforming for Faster Transceiver Discovery

Solution Overview

Problem

Existing beamforming techniques for mobile communication systems face challenges in efficiently discovering a transceiver of interest, leading to high time and energy consumption, and spectrum occupation due to blind beam sweeping and omni-directional patterns.

Innovation Solution

A device or network node determines antenna weights based on spatial information to prioritize transmission on a preferred beamformed direction over others, using techniques such as sequential and non-sequential scanning to optimize beam sweeping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If beam sweeping is employed to discover a transceiver of interest by blindly pointing directive beams in an arbitrary order, then area coverage is improved, but time required for discovery and energy consumption increase

Engineering Contradiction:

Improvearea coverageVSAvoiddiscovery time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The patent applies preliminary action by determining spatial information (location, orientation, movement direction) before performing beam sweeping. This allows the system to pre-calculate prioritized beamformed directions based on the device's spatial state, so that when beam sweeping is executed, it starts from the most promising directions rather than arbitrary ones, thereby reducing discovery time while maintaining area coverage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes parameters by dynamically adjusting beamformed directions based on spatial information parameters (location, orientation, movement). Instead of using fixed arbitrary directions, the system modifies beam directions as parameters to align with the device's spatial state, enabling more efficient scanning that covers necessary areas faster

AI summary

A method performed by a network node of a wireless network includes determining at least one spatial information of a device attached to the wireless network via a radio interface, determining a preferred spatial direction depending on the at least one spatial information of the device, and sending a control message to the device. The control message indicates the preferred spatial direction and prompts the device to execute transmission and/or reception on a plurality of beamformed directions and to prioritize transmission and/or reception on a first beamformed direction of the plurality of beamformed directions over transmission and/or reception on a second beamformed direction of the plurality of beamformed directions.
