Enhanced Paging DCI Resource Utilization in 5G Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR systems, the probability of paging DCI carrying both scheduling information and a short message is low, leading to resource wastage, especially when only short messages are transmitted, resulting in unused resources in the air interface.
Innovation Solution
A method and device for a base station to determine blank resources in paging DCI and load preset information into these resources to form enhanced paging DCI, optimizing the utilization of air interface resources by transmitting cell-level information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging DCI structure includes fixed scheduling information fields, then compatibility with existing systems is maintained, but resource utilization efficiency deteriorates due to blank resources when scheduling information is not needed
Solution Approach 1:
The paging DCI structure is made dynamic by conditionally including or excluding scheduling information fields based on whether scheduling information needs to be transmitted. When only short messages need to be sent, the scheduling information fields are omitted, transforming the fixed structure into a flexible one that adapts to actual transmission needs, thereby eliminating blank resources and improving air interface efficiency while maintaining compatibility when scheduling information is required
Solution Approach 2:
The format of paging DCI is changed from a fixed structure to a variable structure where the presence or absence of scheduling information fields is controlled by a format indicator. This parameter change allows the system to switch between different DCI formats (with or without scheduling information) based on actual needs, resolving the contradiction between maintaining compatibility and avoiding resource waste
2Adaptability or versatility
If paging DCI always carries scheduling information fields, then scheduling capability is ensured, but resource efficiency deteriorates due to unnecessary information transmission
Solution Approach 1:
The paging DCI is segmented into optional components: a mandatory short message field and an optional scheduling information field. This segmentation allows the system to transmit only the necessary components - when scheduling information is not needed, only the short message field is transmitted, eliminating unnecessary data and improving resource efficiency while preserving scheduling capability when required
Solution Approach 2:
Instead of always transmitting complete scheduling information (excessive action), the system transmits only the partial information needed - either just the short message or just scheduling information, or both when necessary. This partial action approach avoids the resource waste of transmitting unnecessary scheduling information while maintaining the capability to transmit it when needed
