摘要
Apparatuses, systems, and methods for a user equipment device (UE) to perform intra-UE co-existence between non-stand-alone (NSA) and stand-alone (SA) mode. The UE may be configured to connect to a first radio access network (RAN) operating according to a first radio access technology (RAT) via a first radio and connect to a second RAN operating according to a second RAT via a second radio. The UE may provide, to the first RAN, configuration information during a radio resource control (RRC) connection procedure. The configuration information may indicate a dual connectivity status of the UE. The dual connectivity status may include indication disabling (enabling) dual connectivity for the UE, working frequencies associated with the second RAN, and/or configurations associated with the second RAN. The UE may receive, from the first RAN, a dual connectivity configuration that may be based on the dual connectivity status of the UE and operate accordingly.

This application claims benefit of priority to Chinese Patent Application Serial No. 201910745595.6, titled “Intra-UE Coexistence between Non-Stand-alone and Stand-alone Mode”, filed Aug. 13, 2019, which is hereby incorporated by reference in its entirety as though fully and completely set forth herein.
The present application relates to wireless devices, and more particularly to apparatuses, systems, and methods for intra-UE co-existence between non-stand-alone (NSA) and stand-alone (SA) mode.
Wireless communication systems are rapidly growing in usage. In recent years, wireless devices such as smart phones and tablet computers have become increasingly sophisticated. In addition to supporting telephone calls, many mobile devices now provide access to the internet, email, text messaging, and navigation using the global positioning system (GPS), and are capable of operating sophisticated applications that utilize these functionalities.
Long Term Evolution (LTE) has become the technology of choice for the majority of wireless network operators worldwide, providing mobile broadband data and high-speed Internet access to their subscriber base. LTE defines a number of downlink (DL) physical channels, categorized as transport or control channels, to carry information blocks received from medium access control (MAC) and higher layers. LTE also defines a number of physical layer channels for the uplink (UL).
