1. A User Equipment (UE) comprising:
transmission and reception circuitry;
storage circuitry; and
a controller,
wherein
the transmission and reception circuitry receives, from a core network, a first Single Network Slice Selection Assistance Information (S-NSSAI), a cause value, and a back-off timer value,
the controller stores the first S-NSSAI in a first rejected NSSAI in the storage circuitry,
the controller starts a back-off timer with the back-off timer value for the first S-NSSAI, and
in a case that the controller deletes the first S-NSSAI from the first rejected NSSAI in the storage circuitry, the controller stops the back-off timer associated with the first S-NSSAI, and
the first rejected NSSAI includes one or multiple pieces of S-NSSAI in which a maximum number of UEs that is capable of being registered per network slice has been reached.
