摘要： A radio access network comprises a donor base station node (29) and a relay base station node (20). The relay base station node (29) participates in communications across a first radio interface with a wireless terminal (30) and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node (28) configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

摘要： The invention proposes a novel method for handling acknowledgement messages between a first protocol layer (L1) and a second protocol layer (L2) in a network node operating as a relay network node (RN). The first protocol layer (L1) is lower with respect to the second protocol layer (L2). The acknowledgement messages (ACK) are related to Automatic Repeat Request (ARQ) processes and the Relay Node (RN) is engaged in an Uplink transmission towards a network access node (eNB). The method comprises a step (10) of receiving a first grant indication by said network access node (eNB) that an Uplink Transmission is granted at said first protocol layer entity (L1) and a step of sending (100) towards said second protocol layer entity (L1) an indication of Acknowledgement (ACK) after receiving a first grant indication. The invention also proposes a corresponding Relay Node (RN).

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.
