Radio Installation Path Determination for Multi-Hop Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communications systems, determining an efficient path between radio stations, especially in ad-hoc modes and when stations are outside direct coverage areas, is challenging due to the need for dynamic subband assignment and routing through multiple hops.
Innovation Solution
A method using a radio installation that subdivides a frequency band into subbands, assigns subbands to each radio station, and determines the path by transmitting path identification information, radio station identification information, and subband information to facilitate data transmission between radio stations, allowing for dynamic routing and subband allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If path determination is performed in ad-hoc mode through multiple hops, then radio stations outside direct coverage areas can communicate, but the complexity of path determination and routing increases
Solution Approach 1:
The patent introduces a radio installation as an intermediary component that assists in path determination between radio stations. The radio installation stores identification information of radio stations and subband assignments, and provides this information to facilitate routing decisions, thereby reducing the complexity burden on individual radio stations while enabling communication across multiple hops
Solution Approach 2:
The patent implements preliminary action by having the radio installation pre-store identification information of radio stations and their subband assignments in a database before communication occurs. When path determination is needed, this pre-stored information is quickly retrieved and provided, avoiding the need for complex real-time calculations and reducing path determination complexity
2Productivity
If dynamic subband assignment is implemented for each radio station, then efficient spectrum utilization is achieved, but the information management and routing complexity increases
Solution Approach 1:
The radio installation serves as an intermediary that centralizes the management of subband assignment information. Instead of each radio station independently managing complex subband assignments, the radio installation stores and provides this information, simplifying the information management task while maintaining dynamic subband assignment benefits
Solution Approach 2:
The system implements feedback mechanisms where the radio installation receives requests for path determination, queries the stored identification information and subband assignments, and provides appropriate responses. This feedback loop enables dynamic subband assignment decisions to be made efficiently based on current network conditions and station capabilities
3Reliability
If complete path information is transmitted to all radio stations, then accurate routing is achieved, but the amount of information transmitted and processing overhead increases
Solution Approach 1:
The patent applies local quality by providing customized information to each radio station based on its specific role in the communication path. Each station receives identification information and subband assignments relevant to its particular routing requirements, rather than all stations receiving identical complete path information, thereby reducing overall information transmission volume while maintaining routing accuracy

AI summary
The invention relates to a method for determining a path between a first radio station and an access point of a radio communications system, whereby the radio communications system comprises additional radio stations. A frequency band subdivided into a number of subbands is used in order to communicate between, the radio stations. At least one subband for communicating is assigned to each radio station. The path extends over one or more of the additional radio stations so that information between the first radio station and the access point can be transmitted over the path. The path is at least partially determined by a radio installation apparatus on request of the first radio station. The radio installation additionally transmits, to at least a portion of the radio stations of the path, respective path identification information, subband information and radio station identification information.
