Uplink Grant Resource Multiplexing in NR Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the new radio (NR) system, uplink grant resources are wasted as they can only be used by specific logical channels corresponding to a certain numerology, leading to inefficient resource utilization due to strict mapping constraints.
Innovation Solution
A method and device for multiplexing uplink grant resources, where a network device transmits control information including uplink grant resources information and multiplexing manner information to a terminal device, allowing it to determine and efficiently multiplex remaining resources across logical channels using global, partial, or undefined multiplexing manners, thereby improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uplink grant resources are mapped to specific logical channels according to numerology, then resource allocation precision is improved, but resource utilization efficiency deteriorates due to wasted remaining resources
Solution Approach 1:
The patent enables uplink grant resources to serve multiple logical channels beyond their primary numerology-mapped channel. Remaining resources that would otherwise be wasted are made available to other logical channels, allowing the same resource to fulfill multiple functions and serve different data transmission needs.
Solution Approach 2:
The patent introduces multiplexing manner information as a configurable parameter that dynamically changes how remaining resources are allocated. By adjusting this parameter, the system can switch between different resource sharing modes (e.g., prioritizing primary channel vs. allowing broader multiplexing), thereby optimizing resource utilization without sacrificing allocation precision.
2Productivity
If remaining uplink grant resources are allocated flexibly across multiple logical channels, then resource utilization efficiency is improved, but system complexity increases due to multiplexing management
Solution Approach 1:
The patent pre-configures multiplexing manner information along with the uplink grant resources. This preliminary action establishes the resource allocation rules in advance, allowing terminal devices to automatically follow predetermined multiplexing patterns without requiring complex real-time decision-making or sophisticated resource management algorithms.
Solution Approach 2:
The patent segments the resource allocation process into distinct components: primary resource allocation based on numerology mapping, and secondary allocation of remaining resources based on multiplexing manner. This segmentation simplifies management by separating the deterministic primary allocation from the flexible secondary allocation, reducing overall system complexity.

AI summary
The present application provides a method and device for multiplexing uplink grant resources, including: determining, by a network device, control information, where the control information includes uplink grant resources information and multiplexing manner information, where the uplink grant resources information is used for indicating uplink grant resources configured by the network device for a terminal device, the multiplexing manner information is used for indicating a multiplexing manner of remaining uplink grant resources, and the remaining uplink grant resources are uplink grant resources in the uplink grant resources except a part of uplink grant resources used for carrying data in one or more logical channels corresponding to the uplink grant resources; and transmitting, by the network device, the control information to the terminal device. The method for multiplexing uplink grant resources of the present application can improve a use efficiency of uplink grant resources.
