be applied to both anchor cell and supplementary cell optionally if there is a supplementary uplink carrier the dtx pattern of both anchor and supplementary uplink carriers may be aligned the network signals only one dtx pattern which is applied to both uplink carriers the initiation or activation and deactivation of the drx and or dtx pattern may be signaled via an hs scch order i e drx activation deactivation bit in an hs scch order from the anchor cell or the supplementary cell and implicitly applied to both cells alternatively an hs scch order may be transmitted via each cell to control drx and or dtx of each cell independently in accordance with the first embodiment the hs scch reception pattern for both carriers may be defined as a set of subframes whose hs scch drx radio frame number cfn_drx and subframe number s_drx satisfy the following equation 5 u00d7 cfn u2014 drx u2212 ue u2014 dtx u2014 drx _offset s u2014 drx mod ue u2014 drx cycle 0 equation 1 where ue_dtx_drx_offset is uplink dpcch burst pattern and hs scch reception pattern offset in subframes and ue_drx_cycle is hs scch reception pattern length in subframes fig4 shows aligned drx patterns for 2 ms transmission time interval tti for ue_drx_cycle 4 top rows 403 show drx pattern on the anchor cell and bottom rows 405 show drx pattern on the supplementary cell the drx patterns for the anchor cell and the supplementary cell are aligned such that the wtru monitors hs scch on subframes 407 and 409 and may receive hs pdsch on subframes 411 and 413 simultaneously in addition if the wtru is not configured to.
