Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference between base stations due to factors such as weather conditions, high transmit power, and antenna positioning leads to degraded signal transmission performance.
Innovation Solution
A method where a target device receives interference information from a first base station, determines a processing mode based on interference parameters, and adjusts the interference by instructing either the first or second base station to modify their transmission parameters or power levels to reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base station transmits signal with high power to improve coverage, then coverage area is improved, but interference to other base stations increases
Solution Approach 1:
The patent changes transmission parameters dynamically by adjusting power levels, frequency resources, and time slots based on interference conditions. The network device coordinates between base stations to allocate different parameters, allowing high power transmission when interference is manageable while reducing power or changing parameters when interference would affect other base stations.
Solution Approach 2:
The patent introduces a network device as an intermediary that coordinates interference management between base stations. This intermediary collects interference information from affected base stations, determines appropriate processing modes, and sends coordination information to both the interfering and affected base stations to resolve the contradiction.
2Length of moving object
If base station uses high antenna position to improve signal reach, then signal reach is improved, but interference to other base stations increases
Solution Approach 1:
The patent adjusts transmission parameters including beamforming directions and antenna port configurations based on the antenna position and interference conditions. By changing these parameters, the system can maintain signal reach while directing energy more precisely to reduce interference to other base stations.
3Reliability
If base station transmits signal to improve communication quality, then communication quality is improved, but interference reception by other base stations increases
Solution Approach 1:
The patent applies local quality by directing transmission energy specifically toward the intended receiver using beamforming techniques. This concentrates the signal in the desired direction to improve communication quality while minimizing energy spillover that would cause interference to other base stations in different directions.
Solution Approach 2:
The patent dynamically adjusts modulation and coding schemes, power levels, and resource allocation based on channel conditions and interference measurements. These parameter changes optimize communication quality for the intended link while adapting to minimize interference impact on other base stations.
4Reliability
If base station increases transmit power to overcome weather conditions, then signal penetration is improved, but interference to other base stations increases
Solution Approach 1:
The patent adjusts transmission parameters including power spectral density, subcarrier spacing, and coding rates to optimize signal penetration through adverse weather conditions. By carefully selecting these parameters, the system achieves sufficient penetration while minimizing total transmitted power and resulting interference to other base stations.
