Abstract:
1. Signaling method for translating iterative algorithms designed according to the best-effort principle for elastic data traffic for decentralized allocation of online transmission power in a wireless network with i transmit nodes and i′ receive nodes forming current directly connected connection pairs ii′, in an interfering transmission channel whose reciprocal transmission behavior is known at the receive nodes i′, in which a primary network is defined by a wireless data traffic of information data to be transmitted and network-controlling signaling data in the interfering transmission channel from the transmit nodes i to the receive nodes i′ in each connection pair ii′, wherein the primary network also includes directional orthogonal low-rate control channels and back channels in each connection pair ii′, and in which an adjoint network is defined by a wireless data traffic of the signaling data in the interfering transmission channel from the receive nodes i′ to the transmit nodes i in each connection pair ii′, wherein the primary network and the adjoint network are alternately used, during the wireless data traffic, for providing the information on the current power state in the network necessary for iterative calculation of the search direction in a selected iterative optimization algorithm, wherein, in the primary network, signaling data are globally synchronously transmitted via the interfering transmission channel in a time pattern agreed between all transmit nodes i, signaling data are locally transmitted via the control channels in each connection pair ii′ with respect to the changeable weighting of the connection priorities, signaling data are locally transmitted via the back channels in each connection pair ii′ with respect to the current state of the transmission channel and a first transmission power matching is performed in the transmit nodes i and wherein, in the adjoint network, the signaling data are predistorted at the receive nodes i′ for compensating the influence of the transmission channel respectively formed in a connection pair ii′ on the interfering transmission channel, the predistorted signaling data are globally synchronously transmitted in a time pattern agreed between all receive nodes i′ via the interfering transmission channel to the transmit nodes i in the connection pairs ii′, and the information on the power state in the network needed for calculating the i-th search direction components in the selected iterative algorithm is calculated, in the transmit nodes i, from the received predistorted signaling data.
