Service-Based Early Measurement Control for Cellular SCell Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G networks face issues with high power consumption and resource wastage due to unnecessary secondary cell (SCell) setup triggered by continuous early frequency measurements, regardless of the service type, leading to increased signaling overhead and inefficient resource utilization.
Innovation Solution
A method and user equipment (UE) that determines whether the service belongs to a first or second service set, temporarily terminating early frequency measurements and reports when it's a first service set, and performing measurements and reporting when it's a second set, thereby optimizing power usage and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the UE continuously performs early frequency measurements for SCell setup, then the setup speed of CA/DC is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the early measurement feature configurable and service-dependent. The network can dynamically enable or disable early measurements based on service requirements, and the UE adapts its measurement behavior accordingly. This resolves the contradiction by allowing fast setup when needed (improving speed) while avoiding unnecessary measurements for services that don't require SCells (reducing power consumption).
Solution Approach 2:
The patent changes the parameter of measurement activation from a fixed state to a service-dependent variable state. By introducing service type as a controlling parameter, the system can adjust whether early measurements are performed based on the specific service being accessed. This enables the system to achieve fast setup for services that need it while conserving power for services that don't require SCell aggregation.
2Speed
If the UE transmits early measurement reports for all services, then the SCell addition is expedited, but the signaling overhead increases
Solution Approach 1:
The patent extracts the early measurement reporting function from being a universal requirement and makes it selective based on service type. By taking out the reporting obligation only when necessary (for services that require SCells), the system reduces unnecessary signaling overhead while maintaining fast SCell addition capability for services that need it. This resolves the contradiction by eliminating redundant reporting for services like voice calls that don't benefit from SCell aggregation.
3Productivity
If the network configures SCell for all early measurement scenarios, then the bandwidth utilization is maximized, but the network resource efficiency decreases
Solution Approach 1:
The patent applies local quality by making SCell configuration service-specific rather than universal. Different service types receive different treatments: services that benefit from high bandwidth (like data transfers) get SCell configuration, while services that don't need it (like voice calls) don't receive SCell configuration. This resolves the contradiction by maximizing bandwidth utilization for services that need it while avoiding wasteful allocation of network resources for services that don't require additional bandwidth.

AI summary
A method, and a user equipment (UE) for power saving through optimized early measurement of frequencies for secondary cell setup in cellular network are provided. The UE initiates a service with a base station associated with a primary cell supporting the early measurement of the frequencies for the secondary cell (SCell) setup. The UE determines whether the service belongs to one of a first service set, and a second service set. The early measurement of the frequencies for the S Cell setup is temporarily terminated, and/or the transmission of an early measurement report comprising the one or more frequencies for the SCell setup to the base station is temporarily terminated. Alternatively, the UE performs the early measurement of the frequencies for the SCell setup and transmits the early measurement report to the base station when the service belongs to the second service set.
