Claim Text:
1. A method for multicarrier wireless communications in a wireless transmit/receive unit (WTRU), comprising: receiving first configuration information for a set of downlink (DL) component carriers and a set of uplink (UL) component carriers, the set of UL component carriers including a primary UL component carrier, and the set of DL component carriers including a primary DL component carrier; receiving a handover command in a radio resource control (RRC) message via one or more of the DL component carriers, wherein the handover command triggers the WTRU to change the primary UL carrier and the primary DL component carrier; applying second configuration information for a new primary UL component carrier and a new primary DL component carrier; receiving signals over the configured set of DL component carriers; and transmitting control information for the configured set of DL component carriers over a physical uplink control channel (PUCCH) only on the new primary UL component carrier, wherein the control information comprises one or more of a channel quality information (CQI) or a precoding matrix index (PMI), a first reporting periodicity and first offset value are used for transmitting control information associated with a first DL component carrier on the PUCCH of the new primary UL component carrier, and a second reporting periodicity and second offset value are used for transmitting control information associated with a second DL component carrier on the PUCCH of the new primary UL component carrier.
