Uplink Signal Transmission via Panel Resource Group Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation mobile communication systems face challenges in handling explosively increasing data traffic, requiring advanced technologies to support higher per-user transmission rates, numerous connecting devices, very low end-to-end latency, and high-energy efficiency, while existing methods struggle to efficiently manage uplink signal transmission across multiple panels with varying radio channel states and antenna configurations.
Innovation Solution
A method for transmitting uplink signals in a wireless communication system by configuring resource groups for multiple panels, where higher layer messages set up resource configurations and lower layer messages activate specific resource groups for transmission, allowing for effective signal transmission based on activated resource groups, even with different radio channel states and antenna configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple panels with different antenna configurations are used to handle increasing data traffic, then the data transmission capacity is improved, but the complexity of managing uplink signal transmission across multiple panels increases
Solution Approach 1:
The patent segments uplink resources into multiple resource groups, where each resource group is associated with a specific panel. This segmentation allows the system to manage uplink signal transmission by selectively activating or deactivating specific resource groups based on panel availability and channel conditions, thereby reducing the complexity of managing multiple panels while maintaining high data transmission capacity
Solution Approach 2:
The patent implements dynamic activation and deactivation of resource groups based on real-time panel status and channel conditions. The network can dynamically switch between different resource groups to adapt to changing system conditions, enabling flexible resource allocation across multiple panels without requiring complex manual configuration
2Use of energy by moving object
If resource groups are selectively activated based on panel status, then the energy efficiency is improved, but the signaling overhead for activation control increases
Solution Approach 1:
The patent combines multiple resource groups into a unified framework where a single activation command can control multiple resource groups simultaneously. This merging approach reduces the number of separate signaling messages needed to activate or deactivate resources across multiple panels, thereby reducing signaling overhead while still enabling energy-efficient selective activation
Solution Approach 2:
The activation mechanism designed in the patent serves multiple functions: it activates resource groups for transmission, indicates panel availability status, and enables energy-efficient resource allocation. This multi-functionality reduces the need for separate signaling messages for each purpose, thereby reducing overall signaling overhead

AI summary
A method for transmitting, by a terminal, an uplink signal in a wireless communication system, according to one embodiment of the present specification, comprises the steps of: receiving an upper layer message related to setting of resource groups for a plurality of panels; receiving a lower layer message related to whether the resource groups are activated; and transmitting an uplink signal on the basis of the lower layer message. The uplink signal is transmitted on the basis of an activated resource group from among the resource groups.
