A communication link is provided between a station of an access system and a relay node. The relay node is a node capable of wirelessly communicating with at least one communication device within the coverage thereof. A set up procedure for the communication link is initiated such that the relay node acts as a communication device towards the station, the set up procedure being initiated according to a set up procedure between the station and communication devices accessing the station directly. Communication between the relay node and at least one communication device within the coverage area thereof are handled such that the relay nodes acts as a station of an access system towards said at least one communication device.

摘要:
There is transmitted to a user equipment UE in a first subframe of a radio frame a downlink shared channel DSCH according to a first relay-transmission mode (e.g., mode A or A′ in the examples); then switch to a second relay-transmission mode (e.g., mode C or C′ in the examples) within the radio frame based on a channel quality of the DSCH. After switching, then transmit to the UE, in a subsequent subframe of the radio frame, the DSCH according to the second relay-transmission mode. In this embodiment the HARQ process is synchronous and non-adaptive for mode C: the eNB re-transmits packets to the UE in a predetermined fashion to be concurrent with transmission of those same packets from the relay node, as scheduled by the eNB. In this embodiment the eNB receives the UE's NACK for the data that is to be retransmitted via relay through the relay node.
摘要:
A method includes receiving information relating to interference between a relay node associated with a first base station and at least one other relay node associated with a second base station. The method also includes initiating modifying transmitting parameters of the relay node and/or the at least one other relay node on the basis of the information.
