Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a narrow radio beam is used to provide high bandwidth communication, then communication bandwidth is improved, but the beam must be continuously adjusted to track the mobile apparatus, causing communication interruptions
Solution Approach 1:
The patent applies dynamics by making the beam steering system adaptive to the mobile apparatus's motion state. The base station receives dynamic state information (velocity, acceleration) from the mobile apparatus and adjusts the beam's rotational radius accordingly. When the apparatus moves faster, the beam rotates with a larger radius to anticipate position changes, maintaining continuous tracking without communication interruptions while preserving high bandwidth.
Solution Approach 2:
The patent implements feedback by having the mobile apparatus continuously transmit its dynamic state information (velocity vector, acceleration vector) to the base station. The base station uses this feedback to dynamically adjust the conical scanning parameters, including the rotational radius of the tracking beam, ensuring the beam remains aligned with the moving apparatus and preventing communication session interruptions.
2Measurement precision
If the base station continuously adjusts the narrow radio beam to track the mobile apparatus, then tracking accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by having the mobile apparatus autonomously measure and report its own dynamic state information (velocity, acceleration) to the base station. This eliminates the need for the base station to complexly track and infer the apparatus's motion, simplifying the beam steering control while maintaining high tracking accuracy through the apparatus's self-provided motion data.
3Device complexity
If conical scanning with a fixed radius is used, then system simplicity is maintained, but tracking performance deteriorates when the mobile apparatus moves
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the rotational radius of the conical scanning beam based on the mobile apparatus's velocity and acceleration. Instead of using a fixed radius, the system modifies the scanning parameter (radius) in response to changing motion conditions, thereby maintaining simple conical scanning architecture while significantly improving tracking performance for moving apparatus.

Implementation Method 2
Any changes in the signal-to-noise ratio of the tracking beam received by the mobile apparatus as the tracking beam rotates about the path is indicative in changes in the location of the mobile apparatus

AI summary
A base station apparatus configured to control operation of a base station causes the base station to perform conical scanning of a mobile apparatus. The base station is configured to communicate via wireless communications using beamforming. A communication session between the base station and the mobile apparatus has been established, and the conical scanning of the mobile apparatus comprises transmitting a tracking beam that rotates about a path centered on a position associated with the mobile apparatus and characterized by a radius. The base station apparatus receives a dynamic state communication indicating a dynamic state of the mobile apparatus; determines, based at least on the dynamic state of the mobile apparatus, a new radius; and causes the base station to perform the conical scanning by transmitting the tracking beam that rotates about the path centered on the position associated with the mobile apparatus and characterized by the new radius.
