Multi-Mode Uplink Grant Allocation for Congestion-Aware Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing uplink grants for multiple modes, particularly in scenarios requiring simultaneous use of different resource allocation methods, leading to inefficiencies and potential congestion.
Innovation Solution
A method and apparatus are developed to determine and utilize both a first and a second mode uplink grant autonomously, allowing simultaneous transmission based on availability, with specific formulas and procedures for logical channel prioritization and resource allocation to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple modes are used for data transmission, then system efficiency and resource utilization are improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent segments the resource allocation process by separating first mode uplink grants (received from network) from second mode uplink grants (determined autonomously). This segmentation allows the system to handle different transmission modes independently while maintaining overall efficiency, reducing the complexity of managing multiple modes simultaneously.
Solution Approach 2:
The patent implements dynamic resource allocation where the UE can adaptively switch between receiving network-scheduled grants and autonomously determined grants based on current channel conditions and traffic requirements. This dynamic approach optimizes system efficiency while managing complexity through flexible, condition-based mode selection.
2Adaptability or versatility
If autonomous determination of uplink grants is implemented, then resource allocation flexibility is improved, but scheduling coordination difficulty increases
Solution Approach 1:
The patent employs preliminary action by having the network pre-configure resource pools and parameters for autonomous grant determination. This preparation reduces the coordination burden during actual transmission, as the UE has advance knowledge of available resources and determination rules, maintaining flexibility while simplifying real-time scheduling coordination.

AI summary
Apparatuses, methods, and systems are disclosed for determining uplink grants for multiple modes. One method (600) includes determining (602), over a first time period, a first mode uplink grant corresponding to a first mode. Determining the first mode uplink grant comprises receiving the first mode uplink grant. The method (600) includes determining (604) autonomously, over a second time period, a second mode uplink grant corresponding to a second mode. The second mode is different from the first mode. The method (600) includes using (606) the first mode uplink grant and the second mode uplink grant to transmit data based on an uplink grant availability corresponding to the first mode uplink grant and the second mode uplink grant.
