Anchor and Non-Anchor Carrier Selection for Wireless Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies due to increased signaling overhead and power consumption during multicarrier operations, particularly in high ON-time requirements, which strain device resources and processing capabilities.
Innovation Solution
Implementing a configuration that allows UEs and base stations to select between anchor and non-anchor carriers based on a first mapping of carrier priorities for operations such as paging messages, RMSI, and random access procedures, thereby reducing ON-time and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multicarrier operations are implemented to support multiple users and services, then system capacity and service diversity are improved, but signaling overhead and power consumption increase
Solution Approach 1:
The patent segments carriers into anchor carriers and non-anchor carriers with distinct functions. Anchor carriers handle critical operations (system information, random access, paging) while non-anchor carriers handle data traffic. This segmentation allows the system to maintain multiple carriers for high capacity while reducing power consumption by selectively activating only necessary carriers for specific operations.
Solution Approach 2:
The patent implements dynamic carrier selection where the UE can switch between anchor and non-anchor carriers based on operational needs. The base station configures multiple carriers dynamically, allowing the system to adapt carrier usage to traffic conditions, thereby optimizing the balance between system capacity and power consumption.
2Productivity
If multiple carriers are activated for high ON-time requirements, then data transmission capacity is improved, but device resources and processing capabilities are strained
Solution Approach 1:
The patent divides carrier functionality into two segments: anchor carriers for control plane operations and non-anchor carriers for user plane data. This segmentation reduces processing complexity by assigning specific task types to specific carriers, allowing the UE to process only relevant operations on each carrier rather than handling all operations on multiple carriers simultaneously.
Solution Approach 2:
The patent extracts critical control functions (system information broadcasting, random access, paging reception) from non-anchor carriers and concentrates them on anchor carriers. This extraction allows non-anchor carriers to focus solely on data transmission, reducing the processing burden on UEs while maintaining high data transmission capacity.
3Reliability
If anchor carriers are used for all critical operations, then system reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The patent segments critical operations across different carrier types: anchor carriers handle system information and random access, while non-anchor carriers can also handle paging and certain control operations. This segmented approach maintains reliability by distributing critical functions across multiple carriers rather than concentrating them all on anchor carriers, thereby improving resource utilization.
Solution Approach 2:
The patent implements multi-functionality where non-anchor carriers can perform both data transmission and certain control functions (paging, some system information). This universality improves resource utilization efficiency by allowing non-anchor carriers to contribute to multiple operational types, reducing the burden on anchor carriers while maintaining system reliability.
4Ease of operation
If carrier selection is simplified to reduce complexity, then ease of operation is improved, but adaptability to different scenarios decreases
Solution Approach 1:
The patent segments carrier selection into two simple categories: anchor carriers for control operations and non-anchor carriers for data operations. This segmentation provides a simple, intuitive selection rule for UEs while maintaining high adaptability, as the base station can configure multiple carriers in each category to suit different operational scenarios and traffic conditions.

AI summary
Various aspects of the present disclosure relate to methods, apparatuses, and devices for wireless communication. A user equipment (UE) may be configured to, capable of, or operable to receive, from a base station, a configuration for selecting one or more of an anchor carrier or a non-anchor carrier, wherein one or more of the anchor carrier or the non-anchor carrier is selected for at least one or more of a paging message, a required minimum system information (RMSI), a random access procedure, or a random access message 4 (msg4), and wherein the configuration comprises a first mapping between a set of carriers and a set of priorities associated with the set of carriers. The UE may be configured to, capable of, or operable to select the one or more of the anchor carrier or the non-anchor carrier.
