Abstract
Official abstract text for this publication.
A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method implemented by a wireless transmit/receive unit (WTRU), the method comprising: receiving a radio resource control (RRC) message via a first downlink component carrier associated with a first site, the RRC message comprising information indicating first search space information for decoding physical downlink control channel (PDCCH) transmissions via the first downlink component carrier associated with the first site, and second search space information for decoding PDCCH transmissions via a second downlink component carrier associated with a second site; receiving a first PDCCH transmission via the first downlink component carrier associated with the first site in accordance with the first search space information; receiving a second PDCCH transmission via the first downlink component carrier associated with the first site in accordance with the first search space information; sending a first transmission via a first uplink component carrier associated with the first site in accordance with the first PDCCH transmission; and sending a second transmission via a second uplink component carrier associated with the second site in accordance with the second PDCCH transmission, wherein the first transmission and second transmission at least partially overlap in time.
