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

VSEngineering 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

Engineering Contradiction:

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.

Inventive Principle:

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.

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.

Inventive Principle:
