State-Based Beam Switching for Wireless Link Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for dynamically managing beam pair links (BPLs) in wireless communications systems are inefficient, leading to increased latency and complexity due to the need for repeated beam training whenever a movement sequence changes, especially in environments with changing communication conditions.
Innovation Solution
Implementing state-based beam switching, where each state of a wireless device is associated with a predetermined beam pair link, allowing devices to cycle through stored BPLs without retraining, and dynamically modifying BPLs to maintain link quality by replacing degraded links with higher quality ones and using repeated transmissions in affected states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques dynamically manage beam pair links by performing beam training whenever movement sequence changes, then link quality can be maintained, but latency and system complexity increase significantly
Solution Approach 1:
The system performs beam training in advance for multiple possible movement sequences and stores the resulting beam pair links. When a movement sequence is executed, the pre-trained beam pair links are directly applied without requiring retraining, thus maintaining link quality while avoiding time-consuming retraining operations.
Solution Approach 2:
The system dynamically selects appropriate beam pair links from stored options based on the actual movement sequence executed. The beam management adapts to changing conditions by switching between pre-configured beam pairs corresponding to different movement states, rather than performing static retraining.
2Adaptability or versatility
If beam training is performed repeatedly whenever movement sequence changes, then communication can adapt to new positions, but device complexity and computational overhead increase
Solution Approach 1:
Multiple beam pair links for different movement sequences are pre-established and stored before actual communication occurs. This preliminary preparation eliminates the need for complex real-time beam training decisions during movement, reducing computational overhead while maintaining adaptability.
Solution Approach 2:
The system creates and stores copies of beam pair link configurations for various movement sequences. These copied configurations can be directly applied when corresponding movements occur, avoiding the need to重新 perform complex beam training procedures and reducing system complexity.
3Reliability
If beam pair links are dynamically updated in real-time, then communication quality is maintained, but processing overhead and energy consumption increase
Solution Approach 1:
Beam pair links are established and stored in advance for anticipated movement sequences. This eliminates the need for energy-intensive real-time beam training during actual movements, as the system can simply retrieve and apply pre-configured beam pairs, thereby maintaining communication quality while reducing energy consumption.
4Adaptability or versatility
If conventional beam management is used without state association, then flexibility is maintained, but retraining is required for every movement change reducing efficiency
Solution Approach 1:
Beam pair links are pre-configured and associated with specific movement states or sequences. This allows the system to maintain flexibility in handling different movement scenarios while improving efficiency by directly applying pre-associated beam pairs without requiring retraining for each movement change.
Solution Approach 2:
The system creates a universal beam management framework where a single set of pre-trained beam pair links can serve multiple movement sequences. This multi-functional approach maintains the flexibility to handle various movements while improving overall communication efficiency by avoiding repeated retraining.

AI summary
Methods, systems, and devices for wireless communications are described. Beam pair link (BPLs) may be associated with a state of a wireless device. For example, a first wireless device may communicate with a second wireless device using a set of BPLs, and the second wireless device may operate using a predetermined movement sequence, where different movements may correspond to the second wireless device using respective states. In some examples, a BPL may be selected for each state of the second wireless device and used to communicate with the first wireless device, where the BPL that corresponds to a particular state may be determined through beam training procedures. In some cases, BPLs associated with respective states may experience decreased link quality and the first wireless device may transmit a configuration that modifies the communications between the first and second wireless devices based on the affected BPLs.
