In the conventional network of the 3rd generation partnership project (3GPP) 5G new radio (NR) , by leveraging AI / ML technology to address challenges due to the increased complexity of foreseen deployments over the air interface, both for the network and UEs. Data collection is a crucial step in AI / ML Life cycle management (LCM) , which provides the foundation for creating effective and accurate models.
[0003] The quality and quantity of the data directly impact the model's performance. Data collection performed by the network (NW) provides a holistic view of the entire network, including the base stations, core networks elements, and other network nodes. Thus, it’s needed a data collection solution for UE to support the NW-side for AI / ML model training. The solution shall allow UE to support configuration and logged a large amount of non-standardized / proprietary data that can be tailored to various UE internal / external conditions and design choices (e.g., UE resource constraints, radio environment, feature engineering) . The 3GPP has recognized these needs and proposed solutions that emphasize the importance of a standard data collection solution.
