Uplink Resource Activation via Preliminary Data Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing uplink resources, particularly in 5G NR and LTE technologies, where pre-allocated resources are not guaranteed to be available for use without an activation indication, leading to potential delays in data transmission and inefficient resource utilization.
Innovation Solution
Implementing a method where communication devices pre-allocate uplink resources and use an activation indication to confirm availability, allowing data preparation before activation and efficient resource management through the use of pre-allocated grants and activation indications, enabling timely data transmission and reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If pre-allocated uplink resources are made available for use without waiting for activation indication, then data transmission speed is improved, but resource allocation reliability deteriorates
Solution Approach 1:
The system performs preliminary data preparation and buffering actions before the activation indication is received. The UE can prepare uplink data in advance and store it in a buffer, so that when the activation indication is received, the data can be transmitted immediately without waiting for preparation, thus achieving both fast transmission and reliable resource allocation.
2Reliability
If activation indication is required before using pre-allocated uplink resources, then resource allocation reliability is improved, but data transmission delay increases
Solution Approach 1:
The UE performs preliminary actions by preparing and buffering uplink data before receiving the activation indication. This way, when the activation indication is received, the data is already ready for immediate transmission, eliminating the delay that would otherwise occur between receiving the activation indication and completing data preparation.
3Productivity
If pre-allocated uplink resources are used without activation indication, then productivity is improved, but resource management complexity increases
Solution Approach 1:
The system implements a self-service mechanism where the UE automatically manages the pre-allocated resources by preparing data in advance and storing it in a buffer. The UE autonomously determines when data is ready for transmission and maintains the buffer, eliminating the need for complex centralized resource management and activation indications, thus improving productivity while reducing management complexity.

AI summary
The present disclosure provides techniques for uplink resource management. For example, a method of wireless communication by a first communication device is provided including receiving, from a second communication device, a configuration allocating at least one uplink resource for use by the first communication device to transmit data on an uplink. The method further includes initiating preparing data for transmission on a first uplink resource of the at least one uplink resource prior to receiving an activation indication for the first uplink resource. The method further includes when the activation indication is received from the second communication device, transmitting uplink data on the first uplink resource to the second communication device. The method further includes when failing to receive the activation indication from the second communication device, refraining from transmitting uplink data on the first uplink resource.
