摘要： A relay node for a wireless network is configured for transmissions on the basis of a radio frame with a plurality of subframes. The relay node includes a first relay path and a second relay path. The first relay path is configured to receive, in a first subframe of the subframes, first unicast transmission signals, to decode the first unicast transmission signals to obtain unicast data, and to forward the decoded unicast data by sending second unicast transmission signals in a second subframe of the subframes. The second relay path is configured to receive, in a third subframe of the subframes, multicast transmission signals, to amplify the received multicast transmission signals, and to send the amplified multicast transmission signals in the third subframe. The relay node may switch between the first relay path and the second relay path in order to implement a hybrid Decode-and-Forward and Amplify-and-Forward relaying operation.

摘要： In order to provide efficient relaying of multicast data in a wireless network, the wireless network comprises a base station and a relay node. The relay node is configured for transmissions on the basis of a radio frame including one or more subframes for unicast transmission and one or more subframes for multicast transmission. In a multicast-only operating mode of the relay node, the base station transmits multicast data to the relay node in one or more subframes which are selectable from the one or more subframes for unicast transmission and the one or more subframes for multicast transmission. The relay node receives the multicast data as transmitted by the base station and transmits the received multicast data in one or more of the subframes for multicast transmission.

摘要： With respect to cooperative signal communication between a mobile terminal (200) and a plurality of access nodes (100-1, 100-2), a combined signal quality value is calculated on the basis of a first individual signal quality value (Q1) of a communication link between a first access node (100-1), e.g. a serving base station, and the terminal (200), and a second individual signal quality value (Q2) of a second communication link between a second access node (100-2), e.g. a supporting base station, and the terminal (200). On the basis of the combined signal quality value, a transmission parameter (50) for future cooperative transmissions is adapted. The transmission parameter (50) may he a modulation scheme, a coding scheme, a transmit power, or a resource allocation.

摘要： In downlink signal communication to a mobile terminal (200), the mobile terminal (200) is associated with a serving access node (100-1). Signal communication to a further mobile terminal (200; 200′″) may interfere with the signal communication between the serving access node (100-1) and the mobile terminal (200). In order to allow interference mitigation at the mobile terminal (200), the serving access node (100-1) obtains scheduling information pertaining to the signal communication to the further mobile terminal (200; 200′″). The obtained scheduling information is then forwarded to the mobile terminal (200) to be used for interference mitigation.
