Switching Period Indication for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of uplink Carrier Aggregation, there is an ambiguity issue regarding switching periods when user equipment (UE) performs dynamic switching between multiple frequency bands, leading to potential interruptions and inefficiencies in data transmission, as current technical specifications only allow for limited reporting of switching periods, which may not accurately reflect the actual switching times used by the UE.
Innovation Solution
The proposed solution involves determining the actual switching period used by the UE when switching between frequency bands and transmitting update information to the network, allowing the network to adjust its scheduling accordingly and ensuring that the switching period in use is accurately reflected, thereby minimizing interruptions and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network uses a predetermined switching period for scheduling, then scheduling is simplified, but data transmission interruptions occur when the actual switching period differs
Solution Approach 1:
The UE feeds back its actual switching period information to the network through update messages. When the UE determines that its actual switching period differs from the predetermined switching period, it transmits an update message containing the actual switching period to the network, enabling the network to adjust its scheduling based on real UE switching behavior
Solution Approach 2:
The switching period information is made dynamic rather than static. The network can update the switching period configuration based on UE feedback, allowing the scheduling parameters to adapt to changing UE switching patterns and operational conditions
2Measurement precision
If the UE reports switching period information frequently, then scheduling accuracy is improved, but signaling overhead increases
Solution Approach 1:
The UE applies different reporting strategies based on local conditions. It determines whether to report switching period information by comparing the actual switching period with the predetermined switching period and only reporting when they differ, rather than reporting continuously or periodically
Solution Approach 2:
The patent extracts only the necessary switching period information for reporting. The UE identifies and reports only the specific parameter (actual switching period) that needs to be updated, rather than transmitting comprehensive UE state information
