Abstract:
1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising: receiving a first radio resource control (RRC) message comprising carrier aggregation information, the carrier aggregation information comprising an indication that downlink control information for downlink transmissions on a first component carrier will be received via a second component carrier, wherein the WTRU receives, via the second component carrier, an indication of which orthogonal frequency division multiplexing (OFDM) symbols of a subframe include a physical downlink shared channel (PDSCH) region for the WTRU to decode the downlink transmissions on the first component carrier; receiving a physical downlink control channel (PDCCH) transmission on the second component carrier, wherein the PDCCH transmission comprises a downlink grant and an index indicating which component carrier is to be used for carrying a physical downlink shared channel (PDSCH) transmission associated with the downlink grant; determining the PDSCH transmission is to be received on the first component carrier based on the index included in the PDCCH transmission received on the second component carrier; and receiving the PDSCH transmission on the first component carrier in accordance with the downlink grant included in the PDCCH transmission received on the second component carrier.
