Abstract: Method for managing available communication resources in a communication network and node (100, 200) for a communication network The invention concerns a method for managing signaling duties in a communication network and a node for a communication network, the node comprising a resource management. The method comprises using at least one signaling duty concerning a requested service for allocating corresponding communication resource of one of the nodes (200), the signaling duty being assigned to a different, further node (100) and the one node (200) being capable for at least partly providing the service. The method further comprises using the one node and the further node for determining a compensation and providing the compensation to said one node.

Abstract: A method is described for managing available communication resource in a communication network comprising nodes (100, 200). Each node comprises a resource management (RM100, RM200) exclusively authorized for managing a part of the communication resource. The method comprises using two of the nodes (100, 200) for agreeing on a compensation and temporarily transferring, from one to the other of the two nodes (100, 200) and during a time interval, authority for managing at least a surplus portion of the managed part of the one node (100, 200) in exchange for the compensation. The communication resource comprises at least one of: frequencies, code books, beamforming vectors, channel inversion matrices, interleavers and decoding strategies.

Abstract: In an OFDM multi carrier modulation method, M sub-carriers are used in a frequency band of a broadband mobile radio channel and several symbols are used in a time band. With application of a MIMO multi-antenna method with T transmitting antennae and R receiving antennae, for all sub-carriers and all symbols, a single, pre-determined, channel-matched transmission strategy is used, which is described by a maximum of T*R complex values on the signal side, independent of the species of the MIMO multi-antenna method and independent of the size of the frequency/time bands.

Abstract: A bidirectional signal processing method uses parallel transmission of digital transmitted data streams in a multiple input-multiple output system. Related art methods generate high bit error rates mostly in singular transmission channels. For this reason, the rank-adaptive signal processing method provides that the number nd of active subchannels are varied according to the actual channel behavior in order to effect a robust data transmission even in singular radio channels based on a transmit-side and receive-side channel knowledge and a modification of the data vector by a linear matrix vector multiplication while introducing a factor gamma for limiting the maximum transmit power. The maximum transmit power is then only distributed to the currently activated subchannels so that no transmit power remains unused. Another optimization of the number of subchannels nd occurs when selecting the modulation and encoding methods.

Abstract: The invention relates to a signal processing method which optimizes the bit error rate under pragmatic conditions. The signalling method is optimally matched to the radio channel, variable with time, in rapid sequence by means of linear operations. Uplink and downlink transmission sides are determined by an excess of antennae on the downlink transmission side. The estimations of the channel matrix in the one transmission direction, necessary for the matching of the transmitter, can, in the absence of common-channel distortions with the condition of channel reciprocity, be directly obtained from the estimations for the other transmission direction. By a suitable linear combination of the transmission signals and, optionally, also the received signals, an error-free bi-directional transmission of data streams can be achieved in Rayleigh and Rice channels with significantly lower transmission powers than in purely receiver-side linear signal processing.
