Carrier Configuration for Selective Offloading Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in carrier aggregation and dual connectivity due to the lack of distinction between mobility and offloading carriers, leading to unnecessary measurements and increased setup times, which can result in resource waste and reduced reliability, especially in applications with strict latency and reliability requirements.
Innovation Solution
Implementing a mechanism that differentiates between mobility and offloading carriers by providing carrier configuration information and type information, allowing user equipment to perform targeted measurements based on specific conditions and conditions, thereby optimizing resource usage and reducing unnecessary measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation and dual connectivity are implemented without distinction between mobility and offloading carriers, then network coverage and capacity are improved, but measurement overhead and setup time increase
Solution Approach 1:
The patent segments carriers into two distinct types: mobility carriers and offloading carriers. This segmentation allows the system to differentiate measurement requirements and procedures for each carrier type, enabling targeted measurements only when necessary and reducing overall measurement overhead and setup time.
Solution Approach 2:
The patent applies partial action by implementing measurements selectively based on carrier type. Full measurement procedures are applied only to mobility carriers, while offloading carriers receive reduced or conditional measurements, thereby reducing unnecessary measurement overhead while maintaining network capacity benefits.
2Reliability
If measurements are performed on all carriers without distinction, then carrier selection reliability is improved, but power consumption and resource usage increase
Solution Approach 1:
The patent segments carriers into mobility carriers requiring reliable measurement-based selection and offloading carriers for which measurements are optional or reduced. This segmentation maintains carrier selection reliability for mobility-critical operations while reducing power consumption by eliminating unnecessary measurements on offloading carriers.
Solution Approach 2:
The patent applies partial measurement action based on carrier type and device state. Measurements are performed fully on mobility carriers, partially or not at all on offloading carriers, thereby maintaining necessary reliability while reducing overall power consumption and resource usage.
3Measurement precision
If measurements are performed on all carriers without distinction, then measurement coverage is improved, but measurement efficiency decreases
Solution Approach 1:
The patent segments measurement procedures based on carrier type, applying comprehensive measurement coverage to mobility carriers while applying reduced or conditional measurements to offloading carriers. This maintains necessary measurement coverage for mobility operations while improving overall measurement efficiency by eliminating redundant measurements.

AI summary
A method, apparatus, and a computer-readable storage medium are provided for configuring carriers and/or performing reference signal measurements. In one example implementation, the method may include a user equipment (UE) receiving carrier configuration information and carrier type information from a network node, the carrier type information including an indication whether a carrier is an offloading carrier; determining whether one or more offloading conditions to perform offloading measurements are satisfied; and performing the offloading measurements in response to determining that the one or more offloading conditions are satisfied. In an additional example implementation, the method may include a network node transmitting carrier configuration information and carrier type information to a user equipment (UE) and receiving offloading and/or mobility measurements from the user equipment (UE), the off-loading and/or mobility measurements generated at the user equipment (UE) based on the carrier configuration information and carrier type.
