Dual registration using dynamic spectrum sharing (dss) in a wide area network (wan)

An apparatus of a user equipment (UE) for wireless communication, comprising:

• an interface;
• and
• one or more processors, which together with the interface, are configured to:
• determine that a wireless communication network supports a dual registration mode and dynamic spectrum sharing (DSS);
• establish a first connection with a first base station using a first radio access technology (RAT) of the wireless communication network, the first RAT using a first operating frequency band;
• determine, based on one or more parameters associated with the DSS, that a second RAT of the wireless communication network has a second operating frequency band that overlaps the first operating frequency band of the first RAT;
• and
• establish a second connection with a second base station using the second RAT based on the dual registration mode and the DSS, the second RAT using the second operating frequency band.

An apparatus for wireless communication, comprising:

• means for determining that a wireless communication network supports a dual registration mode and dynamic spectrum sharing (DSS);
• means for establishing a first connection with a first base station using a first radio access technology (RAT) of the wireless communication network, the first RAT using a first operating frequency band;
• means for determining, based on one or more parameters associated with the DSS, that a second RAT of the wireless communication network has a second operating frequency band that overlaps the first operating frequency band of the first RAT;
• and
• means for establishing, via the second operating frequency band, a second connection with a second base station using the second RAT based on the dual registration mode and the DSS.

A non-transitory computer-readable medium having stored therein instructions which, when executed by a processor of a user equipment (UE), cause the UE to:

• determine that a wireless communication network supports a dual registration mode and dynamic spectrum sharing (DSS);
• establish a first connection with a first base station using a first radio access technology (RAT) of the wireless communication network, the first RAT using a first operating frequency band;
• determine, based on one or more parameters associated with the DSS, that a second RAT of the wireless communication network has a second operating frequency band that overlaps the first operating frequency band of the first RAT;
• and
• establish, via the second operating frequency band, a second connection with a second base station using the second RAT based on the dual registration mode and the DSS.
