Abstract: A relay node receives from user equipments UE CQI reports which give a CQI value per radio band resource RBR, from which are aggregated across the RBRs and/or aggregated per UE across that UE's RBR values. The relay node reports an indication of the average to its controlling access node (eNodeB), either explicitly or implicitly (e.g., a gain applied to the CQI of the downlink between the relay and access nodes). The relay node also checks the UEs' buffer status (actual or predicted) and reports either periodically or based on an underflow/overflow occurrence. For periodic reports, each UE buffer experiencing the overrun/underrun is reported.

Abstract: There is proposed a mechanism for controlling a radio link failure recovery procedure in a communication network having relay nodes, wherein a network control node, such as a DeNB, forwards cached UE context information to a target network node which is contacted by an UE for re-establishment after radio link failure and requests, since it does not have the context information, the context information for the UE in question. Context information can also be proactively forwarded from the network control node to candidate neighboring network nodes when it is detected that a radio link failure between a relay node and the network control node, or between the relay node and a UE is possible.

A corresponding first base station is adapted for controlling and/or for carrying out the above described method.

Abstract: A method transmits data packets in a radio system between an emitter and a receiver. A nominal energy is defined for each data packet and each transmission according to a quality requirement for the reception by the receiver. An emission power required for each data packet is determined according to the quality requirement for the reception of the data packet. The transmission data packet is formed from a plurality of data packets. A first transmission emission power is defined for a first transmission of the transmission data packet according to the determined emission powers for the individual data packet. The first transmission of the transmission data packet is carried out with the first transmission emission power. A retransmission emission power is calculated according to a nominal transmission power derived from the nominal energy, for the transmission data packet and the emission power for at least one previous transmission of the transmission data packet.
