Frequency Domain Paging Resource Allocation in 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR wireless systems, efficient transmission of paging and broadcasted system information is challenging due to the limitations of analog beamforming architectures, which struggle with frequency domain multiplexing and result in costly, time-consuming broadcasts that need to cover the entire cell/sector.
Innovation Solution
The method involves generating and transmitting information related to frequency domain resources for data transmission, indicating whether the resource comprises a first bandwidth or a combination of bandwidths, allowing for efficient allocation and reception of paging and broadcasted system information, thereby optimizing the multiplexing patterns and reducing transmission duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If analog beamforming architectures are used for paging and broadcasted system information transmission, then the transmission can cover the entire cell/sector, but the frequency domain multiplexing becomes difficult and the transmission duration increases
Solution Approach 1:
The patent transitions from time-domain multiplexing to frequency-domain resource allocation for paging and OSI transmissions. By indicating whether to use a first bandwidth or a second bandwidth (combining first and second bandwidths), the system exploits the frequency dimension to achieve wider transmission without increasing time duration, thereby resolving the contradiction between coverage area and transmission duration in analog beamforming architectures
2Area of stationary object
If analog beamforming architectures are used for paging and broadcasted system information transmission, then the transmission can cover the entire cell/sector, but the system overhead increases
Solution Approach 1:
The patent changes the bandwidth parameter dynamically by providing indications to user equipment about whether to monitor a first bandwidth or a second bandwidth for paging and OSI transmissions. This parameter change allows the system to optimize resource usage and reduce overhead while maintaining full coverage capability in analog beamforming architectures
3Productivity
If frequency domain resources are allocated for paging and OSI transmission, then the transmission efficiency improves, but the resource allocation complexity increases
Solution Approach 1:
The patent implements a simplified frequency domain resource allocation by providing indications for only two bandwidth options (first bandwidth or second bandwidth combining first and second bandwidths). This partial action approach avoids the need for complex multi-parameter resource allocation while still achieving improved transmission efficiency for paging and OSI
