摘要： The embodiments of the present invention relate to a method in a transmitting unit; a method in a receiving unit; a transmitting unit and a receiving unit, in a wireless communication network employing Time Division Multiple Access, TDMA, for transmitting and, receiving and demodulating data, respectively, the data being transmitted in a signal comprising a burst, wherein bursts relating to NMS number of mobile stations are multiplexed into a single time slot. The transmission comprises grouping a block of N b number of user code bits, representing the data to be transmitted, into NDS/NMS groups of user code bits. Mapping the groups of user code bits to data symbols such that one group is represented by one data symbol, thereby obtaining a block of data symbols, wherein each data symbol is drawn from one or more pre-defined complex-valued symbol constellation(s). The transmission further comprises repeating the block of data symbols, such that the burst to be transmitted comprises NMS number of equal blocks of data symbols, rotating the NMS number of blocks of data symbols according to a mobile-station-specific rotation, and transmitting the rotated blocks of data symbols in a burst in the time slot.

摘要： Methods, apparatuses, and computer program products provide for routing information between nodes of a radio network. A quality metric is received at a network node that indicates a quality of at least one channel of a plurality of channels in the network. A virtual network is generated that includes one or more routes between a source node and a destination node. A modified virtual network is generated based at least in part on the quality metric and the virtual network, and is then used to determine an optimized route between the source node and destination node. The determination includes a joint selection of one or more of a plurality of network nodes and the plurality of the channels.

摘要： Systems and methods related to distributed route determination through a multi-hop wireless network based on multiple route metrics or properties are disclosed. In some embodiments, a method of operation of a network node comprises identifying a subset of neighbors of the network node in a wireless network based on: (a) link weight(s) for links from the network node to at least some of the neighbors of the network node with respect to route metric(s) and (b) defined limit(s) for the route metric(s). The method further comprises obtaining second link weights for the links from the network node to at least the subset of the neighbors with respect to a second route metric, and identifying from the subset of the neighbors, an optimal next hop neighbor for the network node. In this manner, multiple route metrics are taken into consideration in manner that is computationally efficient.
