Relay System Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems using relays inefficiently allocate wireless resources, leading to waste and reduced data transmission efficiency due to unused resources and interference between uplink and downlink allocations.
Innovation Solution
Implementing a system where relays, terminals, and base stations utilize distinct wireless resources for reception and transmission links, allowing for efficient allocation and reuse of resources by differentiating frequency ranges or time slots, thereby minimizing waste and enhancing data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless resources are allocated to uplinks and downlinks between base station and relay, then data transmission is enabled, but wireless resources are wasted when relays do not operate in certain data regions
Solution Approach 1:
The relay is configured to perform multiple functions: receiving data from base station in first data region, transmitting data to relay terminal in second data region, and receiving/transmitting data in third and fourth data regions. This multi-functional operation eliminates resource waste by utilizing all allocated wireless resources across different data regions for productive communication operations.
Solution Approach 2:
The system dynamically allocates wireless resources across multiple data regions based on communication needs. The relay adaptively operates in different data regions (second and third regions) to transmit and receive data, optimizing resource utilization dynamically rather than being static in a single operational mode.
2Object-affected harmful factors
If relays perform no operation in certain wireless resources, then interference is minimized, but wireless resource waste increases
Solution Approach 1:
The wireless resource spectrum is segmented into multiple distinct data regions (first, second, third, fourth data regions), each allocated for specific communication operations. This segmentation allows the relay to operate in designated regions (second and third) while remaining inactive in others (first and fourth), thereby minimizing interference through spatial-frequency separation while maximizing resource utilization in active regions.

AI summary
A communication system which transmits data using a relay is disclosed. The communication system efficiently divides and allocates wireless resources allocated to a data transmission system to reception and transmission links between a base station and a relay, reception and transmission links between the base station and a terminal, and reception and transmission links between the relay and the terminal.
