Abstract:
1. A method for controlling discontinuous reception (DRX) in a wireless transmit/receive unit (WTRU), the method comprising: the WTRU receiving a DRX configuration comprising a plurality of DRX levels, each of the plurality of DRX levels comprising at least one DRX cycle length; the WTRU operating at a first DRX level of the plurality of DRX levels; the WTRU determining that a WTRU timer has expired; and responsive to determining that the WTRU timer has expired, the WTRU transitioning from the first DRX level to a second DRX level of the plurality of DRX levels without receiving explicit signaling from a base station to transition from the first DRX level to the second DRX level, the second DRX level comprising a second DRX cycle length that is a multiple of a first DRX cycle length of the first DRX level.
