Channel Aware Relay Stations in Enhanced Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current channel aware relay implementations in enhanced relay clusters face challenges in reducing channel overhead while maintaining reasonable design costs and complexity, particularly in networks with cost restrictions or limited relay nodes.
Innovation Solution
The method involves authorizing relay stations within the enhanced relay cluster to receive and process channel information, allowing them to perform channel aware relays independently, reducing the need for frequent reporting to the base station and optimizing resource allocation, while maintaining simple design and low costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If relay stations perform channel aware relays independently with full processing capabilities, then channel overhead is reduced and resource allocation is optimized, but device complexity and production costs increase
Solution Approach 1:
The patent segments the relay station into two distinct parts: a simple relay node that forwards channel information and an authorized relay station that performs channel aware processing. This segmentation allows the system to reduce channel overhead through intelligent processing while keeping most relay stations simple and low-cost.
Solution Approach 2:
The patent applies local quality by authorizing only specific relay stations with particular processing capabilities rather than requiring all relay stations to have complex functionality. This localized enhancement reduces overall system complexity while still achieving channel aware relay benefits in critical areas.
2Productivity
If relay stations perform channel aware relays independently, then resource allocation is optimized and interference is reduced, but design costs and complexity increase
Solution Approach 1:
The patent introduces dynamic authorization where relay stations can be dynamically designated as authorized based on network conditions and requirements. This dynamic approach allows the system to optimize resource allocation where needed while maintaining simple, low-cost relay stations in other areas, balancing productivity and manufacturing ease.
3Device complexity
If centralized control is used for enhanced relay cluster, then relay station design is simple and costs are low, but channel overhead increases and resource allocation flexibility decreases
Solution Approach 1:
The patent introduces authorized relay stations as intermediaries between mobile stations and the base station. These intermediary relay stations perform local channel aware processing and resource allocation decisions, reducing the need for continuous centralized control messages and thereby reducing channel overhead while maintaining simple relay station designs.

AI summary
This invention provides a type of method used for providing channel aware relays in enhanced relay clusters. This method is based on the Centralized Cluster Relay Implementation Proposal, and is implemented by transferring MMR-BS channel information based functions to RS. Specifically, in this invention, RS receives authorization from the MMR-BS to receive the channel information from the MS or next single-hop RS point within its single-hop range, and, after performing applicable channel aware relays, reports the processing result to MMR-BS; MMR-BS configures the signal according to the processing result and joins RS to transmit the control signal to the cluster MS. Using the method provided by this invention can reduce the channel overhead between MMR-BS and RS, and at the same time ensure that the RS composition is simple, and the production costs are low.
