Solution Overview
Problem
Traditional telecommunications networks face limitations in serving high-speed users due to Doppler shifts caused by device velocity, leading to signal degradation and inefficient beam pattern management.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined beam pattern is used in traditional telecommunications networks, then the system structure is simple and easy to implement, but the system cannot effectively serve high-speed users experiencing Doppler shifts
Solution Approach 1:
The patent implements dynamic beam pattern switching that adapts to device velocity. The system transitions from static predetermined beam patterns to dynamic patterns that change based on detected Doppler shifts, allowing the telecommunications system to effectively serve both stationary and high-speed users.
Solution Approach 2:
The system changes beam pattern parameters based on device velocity detection. When Doppler shifts are detected indicating high-speed movement, the system modifies beam pattern characteristics (such as switching between omnidirectional and directional patterns) to maintain effective communication.
2Reliability
If multiple antennas are used to create multiple individually-identifiable beams, then beam directionality is improved, but CPU utilization increases and network infrastructure becomes overburdened
Solution Approach 1:
The system applies partial beamforming by using a subset of available antennas rather than all antennas simultaneously. This provides sufficient signal quality for the user while reducing the computational burden on the network infrastructure, avoiding the need to process signals from all antenna elements.
Solution Approach 2:
The patent segments the antenna array into different groups that can be selectively activated. Instead of using all antennas for every user, the system divides and conquers by activating only the necessary subset of antennas based on user requirements and network conditions.
3Reliability
If traditional predetermined beam patterns are used, then device complexity is low, but the system becomes sensitive to Doppler shifts and signal degradation occurs at high velocities
Solution Approach 1:
The system performs self-service by automatically detecting device velocity and selecting appropriate beam patterns without requiring manual intervention. The telecommunications equipment monitors for Doppler shifts and autonomously adjusts beam patterns to maintain reliable communication.
Solution Approach 2:
The system uses feedback from Doppler shift detection to control beam pattern selection. By monitoring frequency shifts caused by device movement and using this feedback to adjust beam patterns, the system maintains reliable communication while simplifying operation through automatic adaptation.

AI summary
Methods and systems are provided for dynamically adjusting broadcast beam patterns of a wavefront emitted by an antenna array based on the velocities of devices communicatively coupled to the base station associated with the antenna array. The broadcast beam patterns can be adjusted by modifying the broadcast mode or at least one phase, amplitude, or power of the at least one antenna associated with the base station. Adjusting the beam pattern, for example between multiple beams and a single unified beam, based on device types can improve the quality of service for the devices and reduce the processing burden of the base station.
