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 a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.

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: The present invention relates to a method for configuring a retransmission protocol on the uplink between a network node and a relay node in a mobile communication system, the configuration being performed at a network node or at a relay node, and to the corresponding relay node apparatus and network node apparatus capable of configuring the retransmission protocol. In particular, the number of transmission processes is determined based on the position of time intervals available for the transmission and may be selected in order to control the round trip time of the retransmission protocol. Once the number of transmission processes has been configured, the transmission processes are mapped on the available time intervals in a predefined order and repetitively.

Abstract: A radio communication base station device which can reduce the number of judgment times for a control signal in a mobile station, thereby suppressing power consumption by the mobile station. The radio communication base station device (100) includes: a mapping setting unit (122) which sets a mapping method in a mapping unit (102); the mapping unit (102) which maps a control signal to respective mobile stations to any of sub carriers constituting the OFDM symbol according to the mapping method set by the mapping setting unit (122); an MCS setting unit (121) which references a mapping table in which correlation between a plurality of MCS having different MCS levels and mapping methods is set according to the judgment result of the mapping setting unit (122) and sets MCS in encoding/modulation units (101-1 to 101-n).

Abstract: This invention relates to the proposal of component carrier (de)activation message that is allowing a activation or deactivation of one or more component carriers in the uplink or downlink. Furthermore, the invention relates to the use of the new component carrier (de)activation message in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, the invention proposes to use component carrier-specific or cell-RNTI(s) for the scrambling of the CRC of the component carrier (de)activation message, and to explicitly indicate the intended recipient of the component carrier (de)activation message in a corresponding field in the message. Furthermore, the invention further proposes different designs of the component carrier (de)activation message and further uses thereof, so as to trigger CQI reporting and/or SRS transmission by a mobile terminal.
