Network Node Primary Component Carrier Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G and 6G development, face challenges in efficiently managing user assistance information (UAI) for maximum bandwidth (BW) and component carrier (CC) utilization, especially when indications of 0-BW or 0-CC are received, leading to ambiguity in network node behavior and potential disruption of connectivity.
Innovation Solution
The proposed solution involves mechanisms and strategies for network nodes to interpret and respond to UAI indicating 0-BW or 0-CC by configuring the wireless device (WD) to disable or ignore such indications that would exclude the primary component carrier, while maintaining communication on the primary carrier, and allocating carrier power to ensure continuous connectivity and power savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the network node disables all component carriers based on UAI indicating 0-CC, then power consumption is reduced, but connectivity is disrupted
Solution Approach 1:
The patent extracts the primary component carrier from the set of all component carriers and excludes it from disabling operations. When UAI indicates 0-CC, the network node disables secondary component carriers while preserving the primary component carrier, thus achieving power savings without disrupting connectivity. This is implemented by identifying the primary carrier and applying different disabling logic compared to secondary carriers.
Solution Approach 2:
Instead of disabling all carriers indicated by 0-CC and then re-enabling the primary carrier if needed, the patent inverts the approach by explicitly excluding the primary carrier from the disabling operation from the start. This reversal of the disabling logic ensures connectivity is maintained while still achieving power savings on secondary carriers.
2Use of energy by moving object
If the network node reduces bandwidth based on UAI indicating 0-BW, then power consumption is reduced, but network operations are hindered
Solution Approach 1:
The patent extracts the primary component carrier from the bandwidth reduction operation. When UAI indicates 0-BW, the network node reduces bandwidth on secondary component carriers while maintaining the bandwidth configuration of the primary component carrier, thus achieving power savings without hindering essential network operations.
Solution Approach 2:
The patent inverts the bandwidth reduction approach by explicitly preserving the primary carrier's bandwidth configuration rather than reducing it and then attempting to maintain operations. This ensures network operations continue uninterrupted on the primary carrier while power is saved on secondary carriers.
3Use of energy by moving object
If the network node disables all indicated component carriers, then power savings are achieved, but ambiguity in behavior causes connectivity issues
Solution Approach 1:
The patent segments component carriers into two distinct categories: primary component carrier and secondary component carriers. Different disabling behaviors are applied to each segment - secondary carriers are disabled when indicated by 0-CC, while the primary carrier is always preserved. This segmentation eliminates behavioral ambiguity and ensures connectivity is maintained.
Solution Approach 2:
The patent applies different quality characteristics to different parts of the system - the primary component carrier receives special protection and is excluded from disabling operations, while secondary component carriers are subject to normal disabling logic. This local differentiation in treatment resolves the ambiguity and ensures critical connectivity functions are preserved.

AI summary
A method, network node and wireless device (WD) for implementing network strategies for maximum bandwidth (BW) and maximum component carrier (CC) user assistance information (UAI) utilization are disclosed. According to one aspect, a method in a network node includes receiving UAI including an indication of at least one of a zero bandwidth for a frequency band and a component carrier to be disabled. The method also includes determining an allocation of at least one of a bandwidth and at least one component carrier based at least in part on whether the indicated at least one of the zero bandwidth and the component carrier to be disabled would exclude a primary component carrier by which the network node and the WD maintain communication in a cell.
