Uplink Data Transmission Resource Allocation by Class
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE systems fail to effectively allocate transmission resources based on the packet loss rate requirements of different services, leading to difficulties in meeting the diverse transmission needs of uplink data with varying service priorities.
Innovation Solution
The proposed solution involves allocating different transmission resources to uplink data based on distinct transmission classes, which consider reliability, delay, and service priority, allowing user equipment to determine the appropriate transmission format and resources for each logical channel, thereby improving data transmission flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission resources are allocated based on service priority only, then service priority requirements are met, but packet loss rate requirements cannot be ensured
Solution Approach 1:
The patent segments transmission resources by introducing transmission classes that separate packet loss rate requirements from service priority. Different transmission classes (e.g., first transmission class with lower packet loss rate requirement, second transmission class with higher packet loss rate requirement) allow independent allocation based on specific service needs, resolving the contradiction between ensuring reliability and adapting to diverse requirements.
Solution Approach 2:
The patent changes the parameter structure by introducing transmission class as a new dimension for resource allocation. Instead of using only service priority, the system now uses transmission class (which encapsulates packet loss rate requirements) combined with service priority, enabling differentiated resource allocation that simultaneously meets both reliability and adaptability requirements.
2Adaptability or versatility
If single transmission resource allocation is used, then resource allocation is simple, but diverse transmission requirements of different uplink data cannot be met
Solution Approach 1:
The patent segments transmission resources into multiple transmission classes, where each class is designed to meet specific packet loss rate requirements. This segmentation allows the system to handle diverse transmission requirements by selecting appropriate transmission classes, achieving high adaptability without requiring completely separate resource allocation mechanisms for each service type.
Solution Approach 2:
The patent creates a universal transmission class framework that can accommodate multiple types of services with different requirements. The transmission class mechanism serves multiple functions: it categorizes services by packet loss rate requirements, guides resource allocation, and enables flexible adaptation to diverse uplink data needs, thereby achieving versatility without proportionally increasing complexity.
Data Source
AI summary
A data transmission method is provided. The method includes: receiving, by user equipment, first information from a radio access device, where the first information indicates different transmission classes corresponding to a plurality of logical channels; determining, by the user equipment based on the first information, a transmission format of uplink data on at least one logical channel corresponding to at least one transmission class in the different transmission classes, and determining a transmission resource in the transmission format; and sending, by the user equipment, the uplink data by using the transmission format and the transmission resource in the transmission format. In this application, different transmission resources are allocated to uplink data on logical channels (LCHs) of different transmission classes, so that different requirements of different uplink data can be met.
