Solution Overview

Problem

Wireless communication systems face interference issues due to neighboring base stations assigning similar communication resources, leading to degradation of wireless communications and potential errors.

Innovation Solution

A base station configured with a processor and memory generates and sends uplink resource allocation information to other base stations to coordinate resource allocation, allowing for the allocation of orthogonal resources and reducing interference by synchronizing frequency and time slots across adjacent cells.

VSEngineering Contradiction Analysis

1Productivity

If neighboring base stations assign similar communication resources (frequency bandwidth, time slots), then resource allocation efficiency is improved, but interference between cells increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidinterference between cells

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The base station receives uplink resource allocation information from neighboring base stations before assigning resources to wireless communication devices. This preliminary action allows the base station to coordinate resource allocation with neighboring cells, avoiding interference while maintaining efficient resource utilization.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where base stations exchange uplink resource allocation information with neighboring base stations. This feedback loop enables continuous coordination and adjustment of resource allocation to minimize interference while maintaining productivity.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If base stations coordinate uplink resource allocation information exchange, then interference reduction is achieved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism where base stations exchange uplink resource allocation information through a coordinated system. This intermediary approach simplifies the complexity by providing a structured framework for information exchange, reducing the burden on individual base stations while achieving interference reduction.
