The invention relates to methods for improving the DRX operation of a UE by introducing an additional DRX wake-up cycle, which runs in parallel to the short and / or long DRX cycle. The DRX wake-up cycle defines time intervals after which the UE starts monitoring the PDCCH for a wake-up duration of time; the UE does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle between the wake-up durations are preferably shorter than the one of the DRX long cycle, and may have the same or a shorter length than the ones of the DRX short cycle. The wake-up duration may be as long as the on-duration of the DRX short / long cycle, or may be preferably much shorter, such as only one or a few subframes.

System and Method for Promoting Intrinsic Conduction Through Atrial Timing
An atrial based pacing protocol promotes intrinsic conduction. An entire cardiac cycle is monitored for ventricular activity and permitted to lapse with ventricular activity. Ventricular pacing is available in a cardiac cycle immediately subsequent to such a skipped beat. When monitoring for intrinsic ventricular events, an event is expected within a given window. If no such event is detected, the cardiac cycle in truncated, leading to a shorter cycle that is devoid of ventricular activity. The subsequent cycle has a high likelihood of a ventricular sensed event and a greater than normal AV interval is provided prior to pacing.

ActiveUS20090238105A1Avoiding unnecessary excessive stayAvoiding unnecessary excessive stay of short cyclePower managementTransmission systemsTimerEmbedded system
A method for avoiding unnecessary excessive stay of short cycle in discontinuous reception mechanism begins by using the short cycle while the short cycle timer is running. Then, it determines whether the inactivity timer expires or not and whether the short cycle timer expires or not. If the inactivity timer expires but the short cycle timer does not expire, the short cycle is used. If the short cycle timer expires but the inactivity timer does not expire, the long cycle is used. If the inactivity timer and the short cycle timer expire at the same time, either the short cycle or the long cycle is selected for use.

If a monitor measurement cycle is set as a long cycle, promotion in a short cycle cannot be performed; and even if the number of I / Os is very large in response to fluctuations of the number of I / Os in several minutes to several hours of normal work, pages will be promoted after waiting for several weeks. As a result, I / Os which could have normally accepted by an upper tier will be accepted by a lower tier, which results in a problem of worsening the performance efficiency. A monitoring system capable of preventing demotion due to temporary reduction of the number of I / Os for specific pages from a viewpoint of a long cycle and enabling prompt promotion in response to an increase of the number of U / Os for 3the specific pages is realized.A load index value defined from a viewpoint of a long cycle and a load index value defined from a viewpoint of a short cycle are updated based on the number of I / Os which is counted cyclically for each storage area.
