regularly receives its associated dl dch the on time of the rf part using the methods according to the first and second embodiments could be as low as three timeslots out of 15 i e the p ccpch timeslot the dl dch timeslot and the ul dch timeslot as compared to potentially up to seven out of 15 timeslots if every hs scch to be monitored were allocated to a different dl timeslot a slightly modified version of the second embodiment is to allocate hs scchs to the p ccpch or secondary beacon timeslot instead because the wtru 39 s rf part will already be active for measuring dl pathloss for its ul transmissions in a third embodiment of the method shown in fig2 wtru power consumption is decreased by the rnc allocating the hs sich after a hs dsch decoding attempt to a ul timeslot where the wtru regularly sends its associated ul dch see frame 3 of fig2 the hs sich is sent in frame 3 instead of frame 2 because the standard guarantees that there will be a minimum amount of processing time allocated to processing the data in the hs dsch the hs sich containing the acknowledgement or negative acknowledgement for data in a particular hs dsch is therefore not sent in the same frame as the hs dsch is received but typically two frames later as shown in fig2 it is noted that the standard allocates approximately 15 16 timeslots for tdd mode and approximately 7 5 timeslots for fdd.
