Dynamic UE Capability Reporting for Energy-Efficient Protocol Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in wireless communication systems faces inefficiencies in energy consumption and protocol switching when reporting capabilities, particularly when switching between different communication protocols like UMTS Release 99 and enhanced protocols like HSPA or LTE, due to high power consumption and configuration overheads, especially for small data transfers.
Innovation Solution
Implementing a dynamic capability reporting mechanism that allows UE to initially report using a less efficient protocol like UMTS Release 99 for small data transfers to conserve energy and switch to enhanced protocols like HSPA or LTE only when data activity or significance meets certain conditions, thereby optimizing energy efficiency and data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE reports enhanced capability and uses enhanced protocols (HSPA/LTE), then data throughput is improved, but energy consumption increases
Solution Approach 1:
The UE dynamically adjusts its capability reporting based on data activity conditions. When data activity exceeds a threshold, the UE reports enhanced capability to enable high-speed data transfer. When data activity is low, the UE reports basic capability to conserve energy. This dynamic adaptation resolves the contradiction by matching protocol efficiency with actual data transfer needs.
Solution Approach 2:
The invention changes the capability reporting parameter based on data activity conditions. The UE monitors data activity and selectively reports different capability levels (enhanced vs. basic) to the network. This parameter change allows the system to achieve high throughput when needed while consuming less energy during low-activity periods.
2Adaptability or versatility
If UE switches between different communication protocols, then adaptability to different data transfer needs is improved, but configuration overheads increase
Solution Approach 1:
The UE performs preliminary assessment of data activity conditions before switching protocols. By monitoring data activity thresholds in advance, the UE can proactively report enhanced capability when needed, reducing the frequency of protocol switching and associated configuration overheads. This preliminary action prevents unnecessary protocol changes.
Solution Approach 2:
The UE implements a feedback mechanism where it monitors data activity and uses this information to dynamically adjust capability reporting. The feedback loop ensures that protocol switching occurs only when data activity justifies the configuration overhead, balancing adaptability with operational simplicity.
3Speed
If UE uses enhanced protocols for all data transfers, then data transfer speed is improved, but energy efficiency deteriorates
Solution Approach 1:
Instead of always using enhanced protocols, the UE applies enhanced capability reporting partially - only when data activity exceeds a certain threshold. For small data transfers or low-activity periods, the UE uses basic reporting and protocols, avoiding the excessive energy consumption that would result from always using enhanced protocols. This partial application optimizes the balance between speed and energy efficiency.

AI summary
Aspects of the disclosure provide an apparatus and methods for dynamic user equipment capability reporting. A user equipment (UE) is configured to communicate with a network utilizing a plurality of communication protocols including a first communication protocol and a second communication protocol. The UE communicates with the network utilizing the first communication protocol with a maximum achievable throughput less than that of the second communication protocol, and the UE dynamically reports a capability of the UE to transfer data utilizing the second communication protocol in consideration of a power efficiency of transferring an amount of data utilizing the first communication protocol or the second communication protocol.
