Dynamic Radio Resource Allocation in Wireless Relay Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack a protocol mechanism for dynamic allocation of radio resources between base stations and relay stations, leading to suboptimal transmission efficiency and potential resource collisions, as the core network management system is unaware of signal transmission conditions and load conditions between them.
Innovation Solution
A wireless communication system with a protocol mechanism where the relay station transmits system resource information to the base station, allowing the base station to dynamically divide radio resource units into two sets for efficient allocation, enabling optimal signal transmission between the base station, relay station, and user equipment.

Engineering Contradiction Analysis
1Ease of manufacture
If manual adjustment via management system is used for radio resource allocation, then system configuration is simple, but transmission efficiency is suboptimal due to lack of real-time information
Solution Approach 1:
The base station and relay station automatically exchange system resource information and perform dynamic radio resource allocation without manual intervention. The relay station autonomously reports its resource usage to the base station, which then autonomously generates and applies the configuration pattern, eliminating the need for manual management system adjustment while achieving optimal transmission efficiency.
Solution Approach 2:
The relay station provides feedback to the base station about its system resource information including load conditions and signal transmission conditions. This feedback enables the base station to dynamically adjust radio resource allocation in real-time, optimizing transmission efficiency while maintaining simple system configuration through automated decision-making.
2Adaptability or versatility
If base station and relay station independently allocate radio resources, then each station has operational autonomy, but resource collisions occur between them
Solution Approach 1:
The base station acts as an intermediary that coordinates radio resource allocation between itself and the relay station. The relay station reports its resource information to the base station, which then generates a configuration pattern that mediates the allocation decisions of both stations, preventing resource collisions while preserving operational autonomy through the standardized protocol mechanism.
Solution Approach 2:
The radio resource unit is segmented into multiple subunits that can be independently allocated to the base station or relay station based on the configuration pattern. This segmentation allows each station to autonomously use its allocated subunits while the overall protocol prevents collisions through coordinated resource division.
3Productivity
If dynamic resource allocation is implemented, then transmission efficiency is optimized, but system complexity increases due to protocol mechanisms
Solution Approach 1:
The system dynamically changes the allocation parameters of radio resource subunits based on real-time system resource information from the relay station. By adjusting the configuration pattern parameters according to reported load conditions and signal quality, the system achieves optimal transmission efficiency without requiring complex protocol mechanisms beyond the basic information exchange and pattern generation.

AI summary
A wireless communication system is disclosed. The wireless communication system comprises a core network, a base station and a relay station. The relay station transmits a first message with a system resource information of the relay station to the base station. The base station generates a configuration pattern according to the system resource information of the relay station, and transmits a second message with the configuration pattern to the relay station. The configuration pattern is used to divide the radio resource unit of the wireless communication system into a first set and a second set. Therefore, the base station transmits a first signal to the relay station through the first set, and the relay station transfers a second signal with a user equipment through the second set.
