    摘要: The invention relates to methods for detecting at least one of a downlink grant and an uplink grant within a sub-frame of an OFDM-based mobile communication system. The invention provides a reception apparatus (e.g. a relay node or a mobile terminal) that are adapted to perform these methods. The invention defines the uplink grant search space to form a subset of the downlink grant search space. In other words, in the frequency domain, the uplink grant search space is defined on a subset of the resource block pairs that form the downlink search space. This configuration allows downlink data to be mapped to the remaining resources outside the uplink grants search space and the resources used for a downlink grant. Furthermore, the downlink grants comprise an indication of whether the uplink grant search space in the sub-frame comprises (user) data or not.

    摘要: A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions. An allocation unit (106) allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.

    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
