Dynamic Minimum Receiver Levels for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems are limited by strict standards that require default minimum receiver levels for all mobile devices, which do not account for individual device capabilities, leading to inefficient use of base station capacity and coverage area.
Innovation Solution
A base station transmits both a standardized and a non-standardized minimum receiver level, allowing mobile devices to selectively employ the appropriate level based on their ability to utilize carrier aggregation, thereby optimizing communication standards and capacity utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If default minimum receiver levels are used for all mobile devices, then communication reliability is maintained, but base station capacity utilization is inefficient and coverage area is limited
Solution Approach 1:
The patent implements dynamic minimum receiver levels that adjust based on device capabilities. Carrier aggregation-capable devices receive a first minimum receiver level that allows more robust modulation techniques, while non-capable devices receive a second minimum receiver level. This dynamic adjustment optimizes base station capacity utilization while maintaining communication reliability for each device type.
Solution Approach 2:
The patent applies different minimum receiver level standards to different device groups based on their carrier aggregation capability. Carrier aggregation-capable devices are assigned a first minimum receiver level with more robust modulation, while non-capable devices receive a second minimum receiver level. This local differentiation optimizes resource allocation and expands effective coverage area.
2Reliability
If strict default minimum receiver levels are enforced, then communication standard compliance is maintained, but coverage area and device capability optimization are restricted
Solution Approach 1:
The system dynamically selects between a first minimum receiver level for carrier aggregation-capable devices and a second minimum receiver level for non-capable devices. This dynamic approach maintains standard compliance through the second level while optimizing for advanced capabilities through the first level, thereby improving adaptability without sacrificing reliability.
Solution Approach 2:
The patent changes the minimum receiver level parameter based on device capabilities. Carrier aggregation-capable devices operate with a first minimum receiver level that enables more robust modulation techniques, while non-capable devices use a second minimum receiver level. This parameter change allows the system to adapt to different device capabilities while maintaining standard compliance.
3Device complexity
If a single minimum receiver level is used for all devices, then system simplicity is maintained, but resource efficiency and coverage optimization are compromised
Solution Approach 1:
The patent segments mobile devices into two groups based on carrier aggregation capability: devices capable of carrier aggregation and devices not capable of carrier aggregation. Each segment is assigned a different minimum receiver level (first level for capable devices, second level for non-capable devices). This segmentation enables optimized resource efficiency and coverage while maintaining manageable system complexity through clear classification.

AI summary
Methods and systems are disclosed for a dynamic minimum receiver level. A base station can transmit a set of access parameters that enable the mobile device to communicate with the base station. The set of access parameters may comprise a first minimum receiver (RX) level that corresponds to a first standard of qualified communications between the mobile device and the base station utilizing carrier aggregation, and a second minimum RX level that corresponds to a second standard of qualified communications between the mobile device and the base station without utilizing carrier aggregation. The mobile device may be configured to receive the set of access parameters and selectively employ the first minimum RX level so as to communicate with the base station within the qualified coverage area according to the first standard of qualified communications.
