    Abstract: The disclosure 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.

    Abstract translation: 本公开涉及通过引入与短周期和/或长DRX周期并行运行的附加DRX唤醒周期来改善UE的DRX操作的方法。 DRX唤醒周期定义时间间隔，在此之后，UE开始监视PDCCH的唤醒持续时间; 除了监视PDCCH之外，UE在唤醒持续时间内不执行任何其他操作。 唤醒持续时间之间的唤醒周期的时间间隔优选地短于DRX长周期中的一个，并且可以具有与DRX短周期相同或更短的长度。 唤醒持续时间可以与DRX短/长周期的开启持续时间一样长，或者可以优选地更短，诸如仅一个或几个子帧。

    Abstract: The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs.

    Abstract: Methods inform an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Also described is an implementation of these methods by hardware and in software. The invention proposes procedures that allow the eNodeB to recognize the power usage status of a UE in a communication system using carrier aggregation. The UE indicates to the eNodeB when the UE is close to using its total maximum UE transmit power or when it has exceeded the same. This is achieved by the UE including indicator(s) and/or new MAC CEs to one or more protocol data units transmitted on respective component carriers within a single sub-frame that is providing the eNodeB with power status information. The MAC CEs may report a per-UE power headroom. Alternatively, the MAC CEs may report per-CC power headrooms and/or power reductions applied to the respective uplink CCs.

    Abstract: The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.
