Uplink Resource Allocation via Transmission Profile Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, existing methods for allocating uplink resources to logical channels based on priority and bit rate fail to meet the diverse requirements for sub-carrier spacing and Transmission Time Interval (TTI) across different logical channels, leading to inefficient data transmission.
Innovation Solution
A method and device that allocate uplink resources based on transmission profile priorities, where the terminal receives a UL grant and determines the priority of the corresponding transmission profile to select and allocate resources that meet the specific requirements of each logical channel, allowing for flexible allocation of time-frequency resource blocks across different transmission profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uplink resources are allocated based on priority and bit rate of logical channels, then resource allocation simplicity is maintained, but the ability to meet diverse sub-carrier spacing and TTI requirements of different logical channels deteriorates
Solution Approach 1:
The patent segments the resource allocation mechanism by introducing transmission profile priority as a separate dimension from logical channel priority. This segmentation allows the system to handle different sub-carrier spacing and TTI requirements through distinct transmission profiles, while maintaining the original priority-based allocation framework. The resource allocation is divided into profile selection and resource distribution stages, enabling versatile adaptation without overwhelming complexity.
Solution Approach 2:
The patent adds a new dimension to resource allocation by introducing transmission profile priority alongside the existing logical channel priority. This dimensional expansion allows the system to simultaneously consider multiple requirements (sub-carrier spacing, TTI, and priority) without fundamentally changing the allocation mechanism. The multi-dimensional approach enables flexible resource allocation across different transmission profiles while preserving the simplicity of priority-based decisions.
2Productivity
If uplink resources are allocated based on transmission profile priority of logical channels, then data transmission efficiency for diverse services is improved, but the complexity of resource allocation decision-making increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring transmission profiles with their associated priorities, sub-carrier spacing, and TTI parameters before resource allocation occurs. This pre-configuration allows the terminal to quickly match incoming data requirements with appropriate transmission profiles without real-time complex calculations. The UL grant can directly indicate the transmission profile, enabling fast resource allocation decisions that improve transmission efficiency while keeping the decision process simple.
3Adaptability or versatility
If multiple transmission profiles are supported with different priorities, then flexibility in meeting diverse service requirements is improved, but the complexity of managing and allocating resources across profiles increases
Solution Approach 1:
The patent creates a universal resource allocation framework that handles multiple transmission profiles through a unified priority-based mechanism. The same priority comparison and resource allocation logic applies regardless of which transmission profile is selected, making the system multi-functional without increasing operational complexity. The UL grant structure is designed to universally indicate transmission profile priorities, enabling flexible support for diverse services while maintaining consistent management procedures.

AI summary
A method for allocating an uplink resource includes: receiving an uplink (UL) grant sent by a base station; and allocating, based on a transmission profile priority of a logical channel, an uplink resource indicated by the UL grant to the logical channel. In the embodiments of the present disclosure, by allocating the transmission profile priority to the logical channel, the uplink resource that meets the transmission profile priority of the logical channel can be preferentially allocated to the logical channel. Thus, transmission of data on the logical channel can be guaranteed better to meet requirements of communication services.
