SSB Resource Coordination via Request Messages in 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR communications systems, there is a lack of solutions for coordinating resources occupied by cells corresponding to synchronization signal and physical broadcast channel blocks (SSBs) across multiple network devices, leading to resource conflicts and performance degradation.
Innovation Solution
A communication method where network devices send request messages to each other to update or activate SSBs, allowing them to learn and coordinate resource usage by including indication information such as SSB identification, channel bandwidth, and state lists, enabling accurate resource management and coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices independently manage SSB resources without coordination, then device operation simplicity is maintained, but resource conflicts occur and system performance degrades
Solution Approach 1:
The patent implements a feedback mechanism where network devices send request messages to notify others of SSB activation/deactivation decisions. This allows devices to learn about resource usage status and adjust their behavior accordingly, preventing resource conflicts while maintaining relatively simple local decision-making logic.
Solution Approach 2:
The patent introduces request messages as intermediaries that carry indication information between network devices. These messages serve as a communication channel that enables resource coordination without requiring complex direct negotiation or centralized control mechanisms.
2Productivity
If network devices implement comprehensive resource coordination for SSBs, then resource utilization improves and conflicts are reduced, but the complexity of device operation increases
Solution Approach 1:
The patent enables network devices to autonomously make decisions about SSB activation and deactivation based on local conditions. Each device independently manages its resources while using simple request messages to notify others, maintaining operational simplicity while achieving effective resource utilization.
Solution Approach 2:
The request message mechanism provides feedback about SSB status to other network devices, enabling them to adjust their resource allocation decisions. This feedback loop improves overall resource utilization without requiring complex coordination protocols, as each device simply responds to the status information it receives.

AI summary
Examples in this application provide a communication method and a communications apparatus. One example communication method includes generating, by a first network device, load information, wherein the load information indicates load information of at least one synchronization signal and physical broadcast channel block (SSB) of the first network device; and sending, by the first network device, the load information to a second network device.
