1. A method of a User Equipment (UE), the method comprising:
receiving, from a first cell, a first signaling indicative of one or more random access resources of a second cell;
receiving, from the first cell, a second signaling indicative of switching a Special Cell (SpCell) of the UE to the second cell, wherein the second signaling comprises a Medium Access Control (MAC) Control Element (CE); and
in response to receiving the second signaling from the first cell:
applying a Cell Radio Network Temporary Identifier (C-RNTI) for the second cell, wherein the C-RNTI, applied for the second cell to which the SpCell is indicated to be switched to, is indicated by the first signaling received from the first cell; and
initiating a random access procedure on the second cell,
wherein the random access procedure is performed by the UE using at least one of the one or more random access resources indicated in the first signaling received by the UE from the first cell.
