摘要： A data communication method involves combine space time encoding a first set of multiple data elements into a combined space time coded data element. A second set of at least one data element is likewise space time coded into a space time coded data element. The combined data element is transmitted at a transmission slot by a first antenna (112) of a multi-antenna system (110) simultaneously as a second antenna (114) of the system transmits the space time coded data element. The combination STC coding of multiple data elements allows provision of a balance between spatial multiplexing gain and diversity gain in the data transmission and still achieves code rates of more than one.

摘要： The method and arrangement according to the present invention relates to 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 multicast data packets, and subsequently transmits the composite data packets to the receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information, comprising of regular multicast packets, or full or partly decoded composite packets comprised of regular multicast packets, in the process of extracting multicast data packets from the composite data packets.

摘要： A time-frequency resource allocation planner (18) for planning allocation of time-frequency resources to sustain communication links from a common transmitter (TX) to multiple receivers (RX 1 ,..., RX K ) in a wireless OFDMA communication system includes a resource block selector (30) configured to select a set (RBS) of time-frequency resource blocks (RB) for transmission of one packet for each communication link. A communication link quality measure provider (36) is configured to determine a gain-to-interference-plus-noise ratio measure (G k ) for each communication link. A transmit power and transmit rate estimator (34), connected to the resource block selector (30) and the communication link quality measure provider (36), is configured to jointly estimate, within the selected set of time-frequency resource blocks, transmit power (P k ) and transmit rate {R k ) of the packets as functions of determined gain-to-interference-plus-noise ratio measures, to at least approximately minimize expected transmitter energy consumption.

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： 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).
