AI Technical Summary

Technical Problem

Existing dual connectivity (DC) systems face challenges in efficiently coordinating user equipment (UE) capabilities across multiple network devices, particularly when MN and SN are from different vendors, leading to complex UE capability reporting and interdependence issues.

Method used

The UE-based capability coordination mechanism allows the user device to select a combination of candidate resource configurations from separate sets provided by the MN and SN, ensuring the combination does not exceed its communication capabilities, using performance estimates to optimize resource allocation.

Benefits of technology

This approach enables efficient dual connectivity without requiring detailed knowledge of each other's configurations by MN and SN, improving interoperability and optimizing performance metrics like throughput and delay.

Abstract

Devices, methods, apparatuses and computer readable media for a UE-based capability coordination in dual connectivity (DC) are provided In a method, a user device receives a set of first candidate resource configurations. Each of the first candidate resource configurations is available for configuring a first communication between the user device and a first network device. The user device receives a set of second candidate resource configurations. Each of the second candidate resource configurations is available for configuring a second communication between the user device and a second network device. The user device selects a combination of at least one first candidate resource configuration from the set of first candidate resource configurations and at least one second candidate resource configuration from the set of second candidate resource configurations, to enable a DC communication of the user device with the first and second network devices.
