User Equipment QoS Flow Characteristic Reporting for D2D Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional QoS mechanisms in wireless communication systems fail to allocate resources effectively to user equipment as they only consider coarse-grained parameter requirements like latency and packet loss rate, neglecting the characteristics of QoS flows, which results in inadequate resource allocation.
Innovation Solution
User equipment generates and transmits characteristic information, including periodicity and transmission time information of QoS flows, to network side equipment, enabling it to allocate resources based on the specific characteristics of D2D communication, optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station allocates resources based on coarse-grained QoS parameters (latency, packet loss rate) only, then the resource allocation process is simple, but the resource allocation accuracy is insufficient and does not meet user equipment demands
Solution Approach 1:
The patent segments the QoS flow into multiple sub-flows based on different service types and characteristics. Each sub-flow is assigned specific QoS parameters and resource requirements, enabling the base station to allocate resources more accurately according to the specific needs of each sub-flow, thereby improving resource allocation accuracy without significantly increasing overall system complexity
Solution Approach 2:
The patent applies local quality by assigning different QoS parameter sets to different parts (sub-flows) of the overall QoS flow. Each sub-flow receives customized QoS treatment based on its specific service requirements, allowing the base station to optimize resource allocation for each local segment while maintaining overall system manageability
2Loss of information
If the user equipment reports only parameter requirements without QoS flow characteristics, then the reporting overhead is reduced, but the base station cannot obtain fine-grained QoS requirements
Solution Approach 1:
The patent extracts only the essential QoS flow characteristic information that is most relevant for resource allocation from the complete QoS flow description. By selecting and reporting only the critical characteristics (such as service type, periodicity, and key QoS parameters) rather than all possible attributes, the system reduces reporting overhead while preventing information loss about the most important flow characteristics
Solution Approach 2:
The patent implements partial action by reporting a subset of QoS flow characteristics that are sufficient for effective resource allocation. Rather than reporting all possible QoS parameters and flow characteristics, the system reports only the necessary portion that enables the base station to make informed resource allocation decisions, thereby reducing reporting data volume while maintaining allocation accuracy
Data Source
AI summary
User equipment includes a processing circuit, which is configured to: generate characteristics information of a QoS flow for D2D communication between the user equipment and other user equipments, wherein the characteristics information comprises periodicity information and transmission time information of a data service carried by the QoS flow; and transmitting the characteristics information to a network-side device, such that the network-side device allocates, to the user equipment and according to the characteristics information, resources for the D2D communication. By using the user equipment, the electronic device, the wireless communication method, and the computer-readable storage medium, a base station can allocate resources to a user equipment according to the characteristics of a QoS flow, thereby optimizing the process of a base station allocating resources to a user equipment.
