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.
