State transition based on multicast measurement

A wireless device adapted to operate in a wireless communication system, the wireless device comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• transitioning from a connected state to an inactive state;
• receiving, via the at least one transceiver, a multicast session from a network while in the inactive state;
• performing a measurement related to the multicast session;
• and
• initiating a connection resume procedure for transitioning from the inactive state to the connected state based on a result of the measurement related to the multicast session satisfying a certain condition.

A base station comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• transmitting, via the at least one transceiver, a Radio Resource Control (RRC) Release message with a suspend configuration to a wireless device;
• transmitting, via the at least one transceiver, a multicast session to the wireless while the wireless device in an inactive state;
• receiving, via the at least one transceiver, a connection resume request message from the wireless device, based on a result of measurement related to the multicast session satisfying a certain condition;
• and
• transmitting, via the at least one transceiver, the multicast session to the wireless while the wireless device in a connected state.
