## Abstract

A wireless terminal is served by a public land mobile network (PLMN). The wireless terminal comprises receiver circuitry and processor circuitry. The receiver circuitry is configured to receive a first message and a second message. The first message includes a customized mapping configuration which is specific to the wireless terminal and which configures the one or more network slice groups, the one or more of the network slice groups indicating grouping of one or more network slices, the one or more of the network slices providing a designated service(s) within the PLMN, the one or more of the network slice groups being identified by a group index(ies). The second message is dedicated to the wireless terminal and comprises one or more network slice group indices, the one or more of the network slice group indices being associated with a list(s) of one or more carrier frequencies. The processor circuitry configured to select an intended network slice(s); identify, based on the customized mapping configuration, a group index of a network slice group for the intended network slice(s); perform, based on the list of the one or more of the carrier frequencies associated with the group index of the network slice group for the intended network slice(s), a cell reselection procedure.

### Claim 16

A wireless terminal comprising:
receiver circuitry configured to receive a customized mapping configuration and to receive a message dedicated to the wireless terminal, the customized mapping configuration configuring one or more network slice groups, each of the one or more network slice groups comprising one or more network slices identified by respective Single Network Slice Selection Assistance Information (S-NSSAI) in Configured NSSAI provisioned in the wireless terminal, each of the one or more network slice groups being identified by a corresponding group index, the message comprising one or more group indices, the one or more group indices being associated with respective list(s) of one or more radio frequencies; and
processor circuitry configured to:
determine, based on one of the list(s), a radio frequency(ies) on which a network slice group from the one or more network slice groups is supported; and
perform a cell reselection procedure on the radio frequency(ies).

### Claim 17

A method performed by a wireless terminal, the method comprising:
receiving a customized mapping configuration configuring one or more network slice groups, each of the one or more network slice groups comprising one or more network slices identified by respective Single Network Slice Selection Assistance Information (S-NSSAI) in Configured NSSAI provisioned in the wireless terminal, each of the one or more network slice groups being identified by a corresponding group index;
receiving a message dedicated to the wireless terminal, the message comprising one or more group indices, the one or more group indices being associated with respective list(s) of one or more radio frequencies;
determining, based on one of the list(s), a radio frequency(ies) on which a network slice group from the one or more network slice groups is supported; and
