Classification: CPC H | IPC H

Claim 0:
1. A method, comprising:
receiving, at a user equipment (UE), a Cell Radio Network Temporary Identity (C-RNTI);
receiving 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, configuring 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, configuring a virtual PCI of the second component carrier based on RRC signaling;
scrambling information from the UE 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, from the UE, the scrambled information using the second component carrier.
