Classification: CPC H | IPC H

Claim 10:
11. A user equipment (UE), comprising:
one or more hardware processors;
a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instruct the one or more processors to:
receive a Cell Radio Network Temporary Identity (C-RNTI);
receive a message via a first component carrier different from a second component carrier, wherein the message identifies the second component carrier, and instructs the UE to monitor a physical downlink control channel (PDCCH) of the second component carrier for physical downlink shared channel (PDSCH) assignment, wherein the message further indicates whether the second component carrier is of a first component carrier type or a second component carrier type;
in case the second component carrier is of the first component carrier type, configure a physical cell identity (PCI) of the second component carrier based on Radio Resource Configuration (RRC) signaling;
in case the second component carrier is of the second component carrier type, configure a virtual PCI of the second component carrier based on RRC signaling;
scrambling information with a scrambling sequence based on the C-RNTI and the PCI or the virtual PCI of the second component carrier, wherein the PCI or the virtual PCI of the second component carrier is different from a PCI of the first component carrier; and
transmitting the scrambled information using the second component carrier.
