Overlapping Time-Frequency Resource Allocation for Multi-Panel UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G NR systems only allow terminal equipment to perform radio transmissions on one panel at a time, limiting concurrent transmissions and system capacity improvement.
Innovation Solution
A method for determining time-frequency resources for multiple concurrent radio transmissions by considering the antenna panels, ensuring minimal interference and maximizing transmission reliability through index group determination and resource subgrouping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminal equipment is configured with multiple antenna panels, then transmission capacity and system performance can be improved, but the device complexity and resource management difficulty increase
Solution Approach 1:
The patent segments time-frequency resources into distinct resource groups, each associated with specific antenna panels. This segmentation allows the terminal to manage multiple antenna panels independently by allocating specific resource groups to each panel, thereby reducing resource management complexity while maintaining high transmission capacity.
Solution Approach 2:
The patent introduces a new dimension of resource management by associating resource groups with antenna panel indices. This dimensional extension allows the system to track and manage resources across multiple antenna panels systematically, transforming the complex multi-panel resource management problem into a structured multi-dimensional resource allocation framework.
2Productivity
If multiple concurrent radio transmissions are allowed on multiple panels, then system capacity is improved, but interference between transmissions increases
Solution Approach 1:
The patent applies local quality by ensuring that each antenna panel transmits on locally exclusive time-frequency resources. By associating specific resource groups with specific antenna panels, the system guarantees that transmissions from different panels do not interfere with each other, as each panel operates on dedicated resources with unique characteristics.
Solution Approach 2:
The patent introduces resource group indices as intermediaries between antenna panels and time-frequency resources. These indices act as mediators that systematically map antenna panels to specific resource groups, enabling the system to coordinate multiple concurrent transmissions while preventing interference through structured resource separation.
3Reliability
If time-frequency resources are allocated for multiple transmissions, then transmission reliability can be ensured, but resource overlap and interference occur
Solution Approach 1:
The patent changes the parameters of resource allocation by introducing panel-specific resource group associations. Instead of generic time-frequency allocation, the system assigns specific resource groups with unique time-frequency characteristics to each antenna panel, thereby ensuring reliable transmissions while eliminating overlap interference through parameter differentiation.

AI summary
In some implementations, a UE may receive a first signaling indicating a first time-frequency resource group, the first time-frequency resource group being reserved for a first bit block and may receive a second signaling for determining a second time-frequency resource group, the second time-frequency resource group being reserved for a second bit block. The UE transmits the first bit block in time-frequency resources in the first time frequency resource group excluding a first resource subgroup, and transmits the second bit block in the second time-frequency resource group. The first time-frequency resource group and the second time-frequency resource group may be partially overlapping where the first signaling is used to determine a first index group, the second signaling is used to determine a second index group. The first resource subgroup may be determined based on whether the first index group and the second index group belong to the same index set.
