Dynamic Timer Configuration for Coverage Enhancement Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in providing extended coverage and power savings for devices in low-cost applications, especially in poor channel conditions, while advanced repetition schemes can increase bandwidth congestion and power consumption.
Innovation Solution
The system determines an operating mode based on the coverage enhancement (CE) mode supported by User Equipment (UE) and evolved NodeB (eNB), configuring timers to balance coverage, bandwidth, latency, and power consumption by selecting between a first CE mode with fewer repetitions and a second CE mode with more repetitions.

Engineering Contradiction Analysis
1Reliability
If advanced repetition schemes are used to extend coverage, then coverage is improved, but bandwidth congestion increases
Solution Approach 1:
The patent implements dynamic timer configuration that adapts to different coverage enhancement modes. The system adjusts timer values based on the selected CE mode, enabling flexible control over repetition behavior. This dynamic adjustment allows the system to optimize coverage while managing bandwidth usage by not unnecessarily extending timer ranges when high repetition counts are configured.
2Reliability
If advanced repetition schemes are used to extend coverage, then coverage is improved, but power consumption increases
Solution Approach 1:
The system dynamically configures timer parameters based on the coverage enhancement mode. When a lower CE mode is selected with fewer repetitions, the timer range is相应 adjusted to avoid unnecessary extended timing operations. This dynamic adaptation reduces power consumption by matching timer behavior to the actual repetition requirements of the selected CE mode.
3Reliability
If timer range is extended to support more repetitions, then coverage enhancement is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic timer configuration mechanism that adjusts timer ranges based on the selected coverage enhancement mode. Rather than always maintaining maximum timer ranges, the system adaptively scales timer values to match the repetition requirements. This approach provides coverage enhancement capability when needed while avoiding the complexity overhead of always maintaining extended timer infrastructure.

AI summary
Technology for user equipment (UE) and evolved NobeB (eNB) to support enhanced coverage is disclosed. If both the UE and eNodeB provide support for a first and second coverage enhancement (CE) mode, one or more timers of the UE, eNB and a core network (CN) can 5 be configured according to an extended timer range. However, if either the UE or the eNB does not provide support for both the first and second CE modes, the one or more timers of the UE, eNB and CN are configured according to a legacy timer range.
