摘要： The present invention relates to quality-based scheduling of data in wireless networks (1). In this scheduling, quality information (30) representing the degree of decodability of previously transmitted but not correctly received and not successfully decoded data packets (10) is estimated in receiving communications nodes (200). This quality information (30) is reported back to the node (100) that transmitted the packet (10). The quality information (30) will be used by the transmitting node (100) when scheduling subsequent data transmissions. In this scheduling process, at least one of selection of: I) receiving node(s) (200), to which a second data packet (20) is to be forwarded; ii) a type of the data in the second packet (20); and/or iii) a data flow, to which the second packet (20) belongs, is performed based on the quality information (30).

摘要： The method and arrangement according to the present invention relates to of scheduling and coding in communication systems utilizing automatic repeat request (ARQ) and/or multihop scheduling and forwarding. According to the inventive method the receiving nodes selectively stores received information, also overheard information, as a priori information and feed back information about their respective stored a priori information to a sending node. The sending node forms composite data packets by jointly encoding and scheduling multiple data packets, which composite data packets are transmitted to receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information in the process of extracting data for themselves from the composite data packets.

摘要： In a multihop communications network a cost determination method includes determining a plurality of simultaneously potential or favorable next hop nodes for at least one of the nodes between a source and a destination node pair, whereby a mesh-like path comprising a plurality of simultaneously potential routes or paths is defined between the source and destination node. This mesh-like structure is typically determined in a distributed manner and results from a cost optimization process. The cost optimization should preferably consider stochastic variations that for example are caused by the wireless medium.

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. A basic idea of the invention is therefore to determine link cost (S3) 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 (S1) and/or the number of transmit and receive antennas (S2) 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 (S4), and packet forwarding (S5).

摘要： A multihop network (100, 400) and nodes (102a-102q and A-G) are described herein that implement a reactive routing protocol (200) that enables resources of the multihop network (100, 400) to be continuously adapted in a distributed/opportunistic manner in response to a topology change within the multihop network (100, 400) so as to optimize the performance of a connection between a source node (102a, A) and a destination node (102m, E). The types of resources that can be adapted include for example: (1) a route; (2) a channel; and/or (3) physical layer parameters. And, the different types of topology changes that can occur include for example: (1) movement of a node (102a-102q and A-G); (2) quality variations in a channel between the source node (102a, A) and the destination node (102m, E); (3) changes in traffic patterns in the multihop network (100, 400); (4) changes in transmit patterns (e.g., power, beamforming direction) in the multihop network (100, 400); and (5) changes in resource allocations in the multihop network (100, 400).

摘要： The present invention relates to methods and arrangements in a relaying radio node and/or in a sending/receiving radio node, adapted for use in a relaying communication system. The 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 (215) 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 (220) 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 (225) using stored a priori information.
