摘要： The embodiments herein relate to a method in a relay node (110) for relaying data from a first network node (107) to a second network node (101) in a radio communication network (100). The relay node (110)receives the data from the first network node (107) and decodes the received data. The relay node (110) determines a delay constraint of the decoded data and recodes the decoded data. The relay node (110) relays the recoded data to the second network node (101) based on the determined delay constraint and according to a radio communication protocol. The communication between the relay node (110), the first network node (107) and the second network node (101) is based on the same radio communication protocol.

摘要： The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. Link cost is determined for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding.

摘要： A dynamic frequency translating repeater operating in a mobile communications system is operable to receive a multi-user signal and perform time-varying and user-specific frequency shifting in the repeater signal. The dynamic frequency translating repeater may further perform user subcarrier specific dynamic frequency translation. Different mobile stations may be allocated different frequency shift amounts based on the interference environments, resource allocations, and scheduling constraints particular to each mobile station.

摘要： A relaying node is in bidirectional communication with at least a first and a second sending/receiving radio node, and the relaying radio node receives at least a first signal carrying at least first data and a second signal carrying at least second data. The relaying node generates a reduced representation of at least the first and second signal, with a reduced information content as compared to the first and second data, by a joint non-linearly encoding operation, and transmits the reduced representation to at least the first and the second communication node. The first and second sending/receiving node can extract data from the reduced representation by a non-linear decoding operation using stored a priori information.

摘要： A method is implemented in an anchor eNodeB of a network, where the anchor eNodeB communicates with a self-backhauled eNodeB via a radio interface and where the network further includes another eNodeB. The method includes determining whether a user equipment (UE) is being handed off from the first self-backhauled eNodeB to the other eNodeB. The determining is based on: receiving (820) a message from the self-backhauled eNodeB via the radio interface instructing the anchor eNodeB to stop delivering packets that are destined for the UE, or sniffing (1 105, 1 1 10, 1 1 15) into one or more messages sent from the self-backhauled eNodeB to the other eNodeB to identify that the UE is being handed off from the self-backhauled eNodeB to the other eNodeB. The method further includes storing (1 120), based on the determination of whether the UE is being handed off, received packets intended for the UE: and forwarding (1 120) the stored packets to the other eNodeB via a transport network for delivery to the UE.

摘要： A basic idea is to employ multi-user detection (MUD) at the receiver side in a multi-hop network to concurrently decode multiple packets transmitted from multiple nodes (T1, T2), and prioritize among the correctly decoded packets to select one or more packets suitable for forwarding, and finally reply with a packet acknowledgement (ACK) to the corresponding transmitting node for each selected packet. In this way, the design choice of MUD is exploited in the forwarding procedure. It is furthermore beneficial to exploit also the diversity enabled by the existence of multiple relay nodes (R1, R2, R3). A transmitting node that transmits its data packet signal to multiple relay candidate nodes and then receives packet acknowledgements from at least two relay candidate nodes preferably performs a prioritization to select a suitable relay node. The transmitting node then transmits a forwarding order (FO) to the selected relay node, which takes on responsibility for forwarding the information to the next node.
