Reserved Physical Resources for Forward Compatibility in NR Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current New Radio (NR) networks face challenges in maximizing the utilization of time and frequency resources for future services without causing backward compatibility issues, necessitating improved design to achieve forward compatibility.
Innovation Solution
The implementation of reserved physical resources in NR networks, configured semi-statically by gNodeB through higher layers or dynamically indicated, allows for flexible resource allocation and deactivation, prioritization, and efficient spectrum use through mechanisms like explicit signaling and dynamic activation/deactivation of reserved resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical resources are reserved for future services, then forward compatibility is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic reservation where reserved physical resources can be flexibly activated or deactivated based on actual service needs. The gNodeB receives indication information to dynamically control whether reserved resources are used, allowing the system to adapt between preserving resources for future services and utilizing them for current services, thus resolving the contradiction between forward compatibility and resource utilization efficiency
Solution Approach 2:
The patent changes the state parameter of reserved resources from static to dynamic by introducing activation and deactivation mechanisms. Through receiving indication information from higher layers, the system can switch the operational state of reserved resources, enabling flexible adjustment of resource allocation to balance future compatibility requirements with current utilization needs
2Adaptability or versatility
If reserved physical resources are configured, then forward compatibility is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring reserved physical resources in advance for future services. The gNodeB is pre-provided with indication information from higher layers that identifies which resources should be reserved, allowing the system to prepare for future services without ad-hoc complexity when those services are actually deployed
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of indication information from higher layers that mediates between the need for resource reservation and system complexity. This intermediary provides a standardized interface for configuring and managing reserved resources, simplifying the overall system architecture while enabling forward compatibility

AI summary
An apparatus of a New Radio (NR) User Equipment (UE), a method and system. The apparatus includes a radio frequency (RF) interface and one or more processors coupled to the RF interface and configured to: decode a communication from a NR evolved Node B (gNodeB), the communication including information on configuration parameters of reserved physical resources confined within a bandwidth part (BWP) of a wireless channel, the configuration parameters including time and frequency resources; based on the communication, determine the reserved physical resources as being allocated reserved physical resources; and process signals received on, or for communication on, only physical resources not overlapping the allocated reserved physical resources.
