Abstract  Abstract

claims in using carrier aggregation of discontinuous reception (DRX) mode operating wireless transmit/receive unit (WTRU) method and device. In one case the physical downlink (DL) shared channel (PDSCH) is received on the DL component carrier of a particular serving cell (CC) in cell specific activity time period whereby DL CCs and uplink (UL) CC are associated. Then the cell specific activity time period in a physical DL control channel (PDCCH) DL distributed monitoring special service cell and the UL grant for UL CC. In another case the first subset of CC is configured for PDCCH reception second subset of CC is not configured for PDCCH reception. at least one CC of the PDCCH in active time based on the first subset the DRX application to at least one CC in the second subset.

A method and apparatus are described for operating a wireless transmit/receive unit (WTRU) in a discontinuous reception (DRX) mode employing carrier aggregation. In one scenario a physical downlink (DL) shared channel (PDSCH) is received on a DL component carrier (CC) of a particular serving cell during a cell-specific active time whereby the DL CC is associated with an uplink (UL) CC. Then a physical DL control channel (PDCCH) is monitored for DL assignments for the particular serving cell and UL grants for the UL CC during the cell-specific active time. In another scenario a first subset of CCs is configured for PDCCH reception and a second subset of the CCs is not configured for PDCCH reception. DRX is applied to at least one CC in the second subset based on a PDCCH active time of at least one of the CCs in the first subset.
