US 2026/0040155 A1 · METHODS, ARCHITECTURES, APPARATUSES, AND SYSTEMS FOR INTER-RADIO ACCESS TECHNOLOGY BASED ON LOWER LAYER BASED MOBILITY

Abstract

Methods and systems are provided for inter-Radio Access Technology (RAT) mobility prioritization between two wireless networks, each having a RAT, such as 5G and 6G. The methods involve requesting information about each RAT and their respective networks, receiving an indication of a priority of one RAT relative to the other, and performing mobility procedures based on the priority. These procedures include measurement configurations, identifying candidate cells, and activating or deactivating mobility procedures. The system includes a wireless transmit and/or receive unit (WTRU) configured to request information, determine priorities, and perform mobility procedures. Mobility procedures are controlled between different wireless networks based on their conditions and priorities, thereby making efficient use of network resources and enabling seamless transitions between network technologies.

Dependent claims

A method, performed via a first Radio Access Technology (RAT) of a first wireless network, for configuring inter-RAT mobility prioritization associated with the first RAT of the first wireless network and a second RAT of a second wireless network, the method comprising:

receiving, via the second RAT, from the first wireless network, first information comprising a handover configuration and an indication of a priority of the second RAT;
performing, via the first RAT, a first type of Radio Resource Management (RRM) measurement;
based at least in part on the priority, performing, via the second RAT, a second type of RRM measurement;
and
based at least in part on the RRM measurement of the second RAT satisfying a condition:
updating the first type of RRM measurement and the second type of RRM measurement to a third type of RRM measurement and a fourth type of RRM measurement, respectively;
and
initiating a handover procedure to the second wireless network.

A method, performed by a wireless transmit and/or receive unit (WTRU), for configuring inter-Radio Access Technology (RAT) mobility prioritization associated with a first RAT of a first wireless network and a second RAT of a second wireless network, the method comprising:

measuring, via the first RAT, at the first wireless network, first information regarding one or more first conditions associated with at least one of the first RAT or the first wireless network serving the first RAT;
measuring, via the second RAT, at the second wireless network, second information regarding one or more second conditions associated with at least one of the second RAT or the second wireless network serving the second RAT;
receiving, via the first RAT, from the first wireless network, an indication of a priority of the first RAT relative to the second RAT based at least in part on the first information and the second information;
and
performing at least one first mobility procedure associated with the first RAT based at least in part on the priority of the first RAT being greater than the priority of the second RAT;
or
performing at least one second mobility procedure associated with the second RAT based at least in part on the priority of the second RAT being greater than the priority of the first RAT.
