5G Terminal Bandwidth Resource Allocation for Monitoring Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR standard, terminals with bandwidth capabilities less than the system bandwidth face challenges in efficiently monitoring information, as existing methods do not effectively allocate resources for simultaneous monitoring of common and terminal-specific information.
Innovation Solution
A network device allocates a first frequency domain resource to a terminal as a bandwidth part, determines a second frequency domain resource based on the terminal's bandwidth capability, and sends indication information to enable the terminal to monitor common information on the second resource, thereby improving monitoring efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal monitors both common information and terminal-specific information separately on different frequency resources, then the information monitoring completeness is improved, but the monitoring complexity and resource allocation difficulty increase
Solution Approach 1:
The patent combines common information and terminal-specific information into a single downlink control information (DCI) message that is transmitted on the same physical downlink control channel (PDCCH). This merging approach allows the terminal to monitor both types of information simultaneously without requiring separate monitoring procedures, thereby reducing monitoring complexity while maintaining information completeness.
Solution Approach 2:
The downlink control information is designed to serve multiple functions simultaneously: it carries both common information (applicable to multiple terminals) and terminal-specific information (dedicated to a specific terminal). This multi-functionality enables a single monitoring mechanism to handle diverse information types, reducing the overall monitoring burden on the terminal.
2Loss of information
If the network device allocates separate frequency resources for common information and terminal-specific information, then the information separation is improved, but the resource allocation efficiency deteriorates
Solution Approach 1:
The patent merges the allocation of common and terminal-specific information into a single frequency resource allocation decision. The network device determines a single set of frequency resources for the PDCCH that carries both types of information, eliminating the need for separate resource allocation procedures and improving resource allocation efficiency.
Solution Approach 2:
The patent changes the parameter structure of the downlink control information to include both common and terminal-specific fields within a single message. By modifying the DCI format to accommodate multiple information types, the system achieves both information separation (through distinct fields) and resource allocation efficiency (through single resource assignment).
3Loss of information
If the terminal uses its entire bandwidth capability for monitoring, then the monitoring coverage is improved, but the ability to simultaneously monitor terminal-specific information deteriorates
Solution Approach 1:
The patent combines common and terminal-specific information monitoring into a single monitoring operation on the same frequency resources. This allows the terminal to achieve comprehensive monitoring coverage without needing to allocate separate bandwidth portions for each information type, thereby maintaining both coverage and efficiency.
Solution Approach 2:
The terminal uses its full bandwidth capability for a unified monitoring function that serves multiple purposes simultaneously. By designing the monitoring mechanism to be self-sufficient and handle all information types within a single process, the terminal maximizes its bandwidth utilization without requiring additional bandwidth for separate monitoring functions.
