摘要： A hybrid ARQ retransmission method in a communication system, wherein data packets being encoded with a forward error correction (FEC) technique prior to transmission, are retransmitted based on an automatic repeat request and subsequently soft-combined with previously received erroneous data packets either on a symbol-by-symbol or a bit-by-bit basis. The symbols of said erroneous data packets are modulated by employing a predetermined first signal constellation. The symbols of the retransmitted data packets are modulated by employing at least a predetermined second signal constellation. Each symbol bit has a mean bit reliability defined by the individual bit reliabilities over all symbols of the predetermined signal constellation. According to the invention, the predetermined first and the at least second signal constellation are selected such that the combined mean bit reliabilities for the respective bits of all transmissions are averaged out.

摘要： Provided are a radio transmitting apparatus and a control signal transmitting method whereby the number of blind decodings on a control signal receiving side can be reduced without increasing the control signal allocation block rate. In a base station (100), a search space establishing unit (103) establishes two subsets into which a UE-SS established in a second transmission mode different from a first transmission mode has been divided and the number of which is the same as the number of the sub-modes of the first transmission mode, and an allocating unit (106) allocates the mutually different subsets to those two respective sub-modes. Each subset has a plurality of downstream control information allocation area candidates. In this way, the blind decoding area candidates related to DCI format corresponding to each sub-mode can be limited to the subset corresponding to each sub-mode.

摘要： The invention relates to methods for informing an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Furthermore, the invention is also related to the implementation of these methods by hardware and their implementation 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 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.

摘要： The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report.

摘要： The invention relates to a method for dynamically controlling the PUSCH of a SCell in a backhaul link of a communication system utilizing a relay node with carrier aggregation, where the SCell is inband with respect to the access link between the relay node and the UEs. In order to avoid subframe blocking due to inband operation, the PUSCH of an SCell may be deactivated. The new downlink-only configuration of the SCell allows the relay node to use all resources of the SCell for scheduling resources for uplink and downlink transmissions in the access link. The PUSCH may deactivated and activated e.g. depending on the need for higher data rates in the uplink and downlink of the access link between the relay node and the UEs. The decision to deactivate/activate the PUSCH of an SCell may be taken by the DeNB or the relay node.

摘要： 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
