Wireless Resource State Transition for Beam Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing beam failures in beamformed wireless transmissions, leading to communication disruptions and reduced reliability.
Innovation Solution
The method involves configuring a wireless resource to have two states: an active state for data communications and an inactive state for beam failure recovery procedures. Upon detecting a communication failure, the wireless resource is transitioned from the active state to the inactive state, allowing for the execution of a beam failure recovery procedure using the resource in its inactive state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless resources are continuously used for data communications, then communication productivity is maintained, but beam failure recovery cannot be performed timely
Solution Approach 1:
The wireless resource is configured to dynamically switch between two states: active state for data communications and inactive state for beam failure recovery procedures. This dynamic state transition allows the system to adapt resource allocation based on operational needs, ensuring timely failure recovery while maintaining communication efficiency during normal operation
Solution Approach 2:
The wireless resource allocation is segmented into distinct functional states rather than being continuously dedicated to a single function. By dividing the resource usage into active (data communication) and inactive (failure recovery) states, the system can allocate resources appropriately for each specific operational requirement
2Reliability
If wireless resources are dedicated for beam failure recovery procedures, then recovery reliability is improved, but data communication capability is reduced
Solution Approach 1:
The system employs dynamic state transition where the wireless resource alternates between active state (supporting data communications) and inactive state (supporting beam failure recovery). This dynamic allocation ensures that resources are dedicated to failure recovery only when needed, rather than being permanently reserved, thus maintaining data communication capability during normal operation
Solution Approach 2:
The wireless resource is designed to serve multiple functions through its dual-state configuration. The same resource can be used for both data communications (when in active state) and beam failure recovery procedures (when in inactive state), making the system more versatile and efficient

AI summary
Methods, systems, and devices for wireless communications are described. A wireless device may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The wireless device may determine that a communication failure has occurred during a first communication period. In some cases, one or more techniques for confirming the communication failure may be used to verify the failure. The wireless device may transition during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The wireless device may perform the communication failure recovery procedure using the resource transitioned to the second state.
