Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a mechanism of an improved discontinuous reception operation in a mobile terminal.

SOLUTION: A DRX operation of user equipment is improved by introducing an additional DRX wake-up cycle which runs in parallel to a short and/or long DRX cycle. The DRX wake-up cycle defines time intervals and after the time intervals the user equipment starts monitoring a PDCCH for a wake-up duration. The user equipment does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle sandwiched between the wake-up durations are preferably shorter than that of the long DRX cycle and may have the same or a shorter length than that of the short DRX cycle. The wake-up duration is as long as the on-duration of the short/long DRX cycle or preferably much shorter (for example only one or a few sub frames).
