Beam Switch Interruption Time for 5G Component Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G and LTE technologies, face challenges in managing beam switching delays that exceed threshold values, leading to potential interruptions across active component carriers, especially in high-frequency bands where beam switching delays cannot fit within the cyclic prefix duration of OFDM symbols.
Innovation Solution
Implementing a beam switch interruption time across one or more active component carriers when the beam switching delay exceeds a threshold value, allowing for additional time to accommodate the delay and prevent interruptions, particularly in scenarios with large subcarrier spacings like FR4.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If beam switching is performed in high-frequency bands with large subcarrier spacings, then communication speed and spectral efficiency are improved, but beam switching delay exceeds the cyclic prefix duration causing communication interruptions
Solution Approach 1:
The patent applies preliminary action by configuring a beam switch interruption time parameter before beam switching occurs. This parameter is pre-configured based on the beam switching delay of the UE, allowing the system to prepare adequate guard time in advance to prevent communication interruptions during beam switching in high-frequency bands
Solution Approach 2:
The patent changes the time parameter by introducing a beam switch interruption time that is configured based on the UE's beam switching delay characteristics. This parameter adjustment allows the cyclic prefix duration to accommodate the beam switching delay, thereby preventing interruptions while maintaining high communication speed
2Reliability
If beam switching delay is reduced to fit within cyclic prefix duration, then communication continuity is maintained, but additional time for beam switching is limited affecting adaptability
Solution Approach 1:
The patent applies dynamics by making the beam switch interruption time adaptive to each UE's specific beam switching delay characteristics. The network entity configures this parameter dynamically based on UE capabilities, allowing each UE to have optimized guard time that matches its hardware characteristics while maintaining communication continuity
Solution Approach 2:
The patent changes the time parameter by configuring beam switch interruption time based on measured or reported beam switching delays. This parameter customization allows the system to adapt to different UE hardware capabilities while ensuring communication continuity through adequate guard time allocation
3Productivity
If beam switching is performed without sufficient guard time, then productivity is improved by avoiding interruptions, but beam switching delay causes communication failures
Solution Approach 1:
The patent applies preliminary action by pre-configuring the beam switch interruption time parameter before beam switching operations. This pre-configuration ensures that adequate guard time is allocated in advance based on the UE's beam switching delay characteristics, preventing communication failures while maintaining productivity
Data Source
AI summary
A user equipment (UE) detects a beam switching event and switches, in response to the beam switching event, a beam for communications on a first active component carrier. The UE applies a beam switch interruption time across one or more second active component carriers if a beam switching delay associated with the beam switch exceeds a threshold value.
