1. A method performed by a wireless transmit receive unit (WTRU), the method comprising:
receiving configuration information, wherein the configuration information indicates a plurality of downlink carriers and indicates a plurality of physical control channel resources for feedback;
receiving a physical downlink (PHY DL) control signal comprising scheduling information associated with a downlink transmission for reception on one of the plurality of downlink carriers and an indication of at least one of the plurality of physical control channel resources, wherein the indication indicates a starting symbol, a symbol length, and a subcarrier for feedback transmissions;
receiving the downlink transmission on the one of the plurality of downlink carriers; and
transmitting feedback for the downlink transmission using the at least one of the plurality of physical control channel resources indicated by the PHY DL control signal.
