Classification: CPC H | IPC H

Claim 0:
1. A method performed by a wireless communication node, comprising:
receiving a random access preamble from a wireless communication device which currently camps in a first cell in which a first radio access technology (RAT) is used,
transmitting a message to the wireless communication device for the wireless communication device to select a second cell to transition to, wherein:
a second RAT, different from the first RAT, is used in the second cell,
the message comprises information indicating whether to stay in the first cell or to transition to the second cell based on respective measured reference signal received power (RSRP) values in the first and second cells and a predefined offset between the respective RSRP values, wherein the information comprises:
scheduling information of a multimedia broadcast multicast service (MBMS) provided by the first and second cells, and
cell selection criteria information for the wireless communication device, wherein the cell selection criteria information indicates that:
the wireless communication device selects either the first cell to stay or the second cell to transition to using an enhanced machine-type communication (eMTC) technology when the wireless communication device is in a normal coverage mode, and
the wireless communication device selects either the first cell to stay or the second cell to transition to using a narrowband internet-of-things (NB-IoT) technology when the wireless communication device is in an enhanced coverage mode.
