Communication Terminal Power Adjustment for Out-of-Band Emission Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power reduction methods in communication terminals result in reduced uplink coverage and communication efficiency due to stringent out-of-band emission requirements, particularly in sparsely populated areas where such limitations are unnecessary.
Innovation Solution
Determine out-of-band emission limitation information based on geographic features and regulatory requirements to adjust power levels, allowing for relaxed emission constraints in specific situations, thereby reducing unnecessary power reduction and enhancing uplink coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict out-of-band emission requirements are applied to meet regulatory standards, then emission compliance is improved, but uplink coverage and communication efficiency deteriorate
Solution Approach 1:
The patent applies dynamics by making the out-of-band emission limitation configurable rather than fixed. The network device can dynamically adjust the emission limitation parameter based on terminal capability and deployment scenario, allowing the system to adapt between strict compliance mode and relaxed coverage mode. This resolves the contradiction by enabling the emission requirement to change according to operational needs rather than being static.
Solution Approach 2:
The patent changes the emission limitation parameter from a fixed regulatory constant to a configurable parameter. By introducing a parameter that can be adjusted between different limitation levels, the system can optimize for either emission compliance or uplink coverage depending on the scenario, thus resolving the technical contradiction between these two opposing requirements.
2Reliability
If power reduction is applied to meet out-of-band emission requirements, then emission limitations are satisfied, but communication efficiency and productivity deteriorate
Solution Approach 1:
The patent makes the power reduction requirement dynamic by allowing the network device to configure different emission limitation levels. When high communication efficiency is needed, the system can reduce power reduction requirements (within acceptable limits), and when emission compliance is prioritized, stricter limits are applied. This dynamic adjustment resolves the contradiction between emission satisfaction and communication efficiency.
Solution Approach 2:
By changing the emission limitation parameter to be configurable, the system can adjust the degree of power reduction required. This parameter change enables the system to optimize communication efficiency by reducing unnecessary power reduction while still meeting acceptable emission limitations, thus resolving the productivity contradiction.
3Reliability
If uniform out-of-band emission limitations are applied across all locations, then regulatory compliance is maintained, but uplink coverage in special locations deteriorates
Solution Approach 1:
The patent applies local quality by allowing different out-of-band emission limitations to be applied to different locations or deployment scenarios. Instead of a uniform global limitation, the network device can configure location-specific emission requirements based on terminal capability and local regulatory environment. This enables special locations to have relaxed limitations for improved coverage while other locations maintain strict compliance.
Solution Approach 2:
The patent creates a universal configuration mechanism that can handle multiple scenarios through a single adaptable parameter. The emission limitation parameter serves multiple functions: it can enforce strict regulatory compliance in standard deployments, provide relaxed limitations in special locations, and scale between different compliance levels. This multi-functionality resolves the contradiction between uniform compliance and location-specific optimization.
