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： The invention relates to a downlink transmission scheme that supports downlink HARQ operation and macro-diversity that is capable of overcoming the problem of HARQ protocol de-synchronization when using HARQ in the downlink with multiple data transmitting network nodes. In this scheme, a distributed HARQ protocol operation for downlink data transmissions involving multiple network nodes is provided, where only one network node is terminating downlink HARQ protocol operation towards to mobile terminal, i.e. retransmissions of a data packet are sent from a single network node, a single HARQ transmitter, to the mobile terminal. The multiple network nodes send a first transmission of the data packet to the mobile terminal in a single transmission time interval using HARQ. One of the multiple network nodes is designated as the HARQ terminating node that controls/handles all retransmissions of the data packet.

摘要： A radio transmitting apparatus and the like for improving the reception error rate characteristic. In this apparatus, a data modulating part (121) modulates a data signal to provide a modulated symbol. A Q-inverting part (125) generates a symbol that corresponds to the modulated symbol provided by the data modulating part (121) and that, when combined with the modulated symbol, becomes a signal having a particular value.
