Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications networks, traditional beam management methods are inefficient in determining the correct reception beam for wireless devices, leading to overhead and time inefficiencies in obtaining beam reports due to the lack of directionality knowledge by network nodes.
Innovation Solution
Implementing a method where network nodes schedule wireless devices to provide beam reports in a common time/frequency resource using a cell-covering reception beam created by an analog beamforming network, allowing for simultaneous monitoring of beam reports from all directions within the cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network node uses narrow reception beams to monitor beam reports, then the directionality and precision of beam monitoring is improved, but the network node cannot simultaneously monitor multiple wireless devices from different directions
Solution Approach 1:
The patent segments the beam monitoring process into two distinct phases: (1) a first beam sweep for initial direction estimation where the network node transmits reference signals in multiple directions and the wireless device reports back the best beam, and (2) a second beam sweep for actual beam report monitoring where the network node uses the previously determined direction to monitor the wireless device. This segmentation allows the system to achieve both high precision monitoring and efficient resource utilization.
2Area of stationary object
If the network node transmits reference signals in multiple transmission beams for beam sweeping, then the coverage and accuracy of beam discovery is improved, but the overhead and time required for beam management increases
Solution Approach 1:
The patent applies preliminary action by having the network node perform a first beam sweep to estimate the initial direction of the wireless device before the actual beam report monitoring phase. During this preliminary phase, the network node transmits reference signals in multiple directions and the wireless device reports back the best beam. This preliminary direction estimation eliminates the need for extensive beam sweeping during the monitoring phase, significantly reducing the time and overhead while ensuring comprehensive coverage.
