Relay Node Access via Indication Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems like LTE-A, the introduction of Relay Nodes (RN) creates a need for an efficient access method to enable RNs to access the wireless access network, as existing solutions do not effectively address the challenge of accessing transmission resources.
Innovation Solution
The proposed method involves a first transmission point receiving indication information from a second transmission point, which indicates its support for the relay function, allowing the first transmission point to access the wireless access network and obtain necessary transmission resources based on the transmission level or hop number, thereby improving access efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If relay nodes are introduced to extend network coverage, then network coverage is improved, but access efficiency deteriorates due to lack of effective access method
Solution Approach 1:
The patent applies preliminary action by having the second transmission point send indication information about relay function support and transmission resources before the first transmission point attempts to access the network. This advance notification allows the relay node to efficiently obtain transmission resources without trial-and-error access attempts, thus improving access efficiency while maintaining extended network coverage
Solution Approach 2:
The patent implements feedback through the indication information mechanism where the second transmission point provides feedback about its relay capabilities and available transmission resources to the first transmission point. This feedback loop enables the relay node to adjust its access strategy and efficiently acquire resources, resolving the contradiction between network coverage extension and access efficiency
2Ease of operation
If relay nodes access the network without indication information, then access procedure is simple, but transmission resources cannot be obtained efficiently
Solution Approach 1:
The patent introduces indication information as an intermediary element that carries relay function support status and transmission resource details from the second transmission point to the first transmission point. This intermediary mechanism maintains operational simplicity by using a standardized information exchange protocol while significantly improving transmission resource acquisition efficiency through informed access decisions

AI summary
Provided are an access method and transmission point. In the embodiments of the present invention, indication information sent by a second transmission point is received by means of a first transmission point and is used for indicating that said second transmission point supports relay functionality, such that said first transmission point is capable of accessing, according to the indication information, the wireless access network on which the second transmission point is located; thus the first transmission point is taken as a relay node and accesses the wireless access network.
