Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current D2D communication methods in wireless networks face inefficiencies in radio resource management, particularly in the selection of radio resource allocation modes, leading to potential Quality of Service (QoS) issues and inefficient resource utilization.
Innovation Solution
The introduction of new radio configuration parameters by the network to control D2D Autonomous Mode, allowing UEs to adapt radio resource usage based on network needs, and the implementation of default radio resource allocation modes (Scheduled Mode or Autonomous Mode) per cell to manage resource allocation dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Autonomous Mode radio resource allocation is used for D2D communication, then device autonomy and operation simplicity are improved, but Quality of Service and radio resource efficiency deteriorate
Solution Approach 1:
The patent implements dynamic radio resource allocation mode selection, where the network can switch between Autonomous Mode and Scheduled Mode based on current network conditions, traffic load, and QoS requirements. This allows the system to adapt resource allocation strategies in real-time, optimizing both device autonomy and service quality according to varying operational contexts.
Solution Approach 2:
The patent introduces configurable parameters including an Autonomous Mode pool size parameter that controls the number of radio resources available for autonomous D2D communication. By dynamically adjusting this parameter, the network can balance between allowing sufficient device autonomy and maintaining adequate resource control to ensure QoS requirements are met.
2Ease of operation
If Autonomous Mode radio resource allocation is used for D2D communication, then device autonomy and operation simplicity are improved, but radio resource efficiency deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where UEs report their D2D communication status, resource usage, and channel conditions to the network. The network uses this feedback information to make informed decisions about resource allocation mode selection and Autonomous Mode pool configuration, thereby optimizing radio resource efficiency while maintaining appropriate device autonomy.
Solution Approach 2:
The system dynamically adjusts the Autonomous Mode pool size and composition based on real-time network conditions and observed resource utilization patterns. This dynamic adjustment ensures that radio resources are efficiently allocated - neither over-provisioning which would waste resources nor under-provisioning which would limit D2D communication effectiveness.
3Quantity of substance
If a larger Autonomous Mode pool is provided for D2D communication, then more radio resources are available for autonomous allocation, but resource management complexity and potential waste increase
Solution Approach 1:
The patent introduces a configurable Autonomous Mode pool size parameter that allows the network to precisely control the number of radio resources allocated for autonomous D2D communication. This parameter can be adjusted based on network conditions, ensuring an optimal balance between providing sufficient resources and maintaining manageable resource management complexity.
Solution Approach 2:
The patent applies different resource allocation strategies to different spatial locations, service types, and QoS requirements within the network. Rather than using a uniform Autonomous Mode pool for all D2D communications, the system tailors resource allocation to local conditions, reducing overall management complexity while ensuring adequate resources are available where needed.
