Abstract: The invention relates to a method for transmitting signals in a radio communication system consisting of at least two frequency signal-transmitting channels. At least the first (fcoord) of said frequency channels is used for organising radio resources, and at least the second (fi) of the frequency channels is used for transmitting signals between the stations of the system where the signal transmission is carried out by the frequency channels from/in a direction of said stations in conformity with a predefined temporal pattern (P1, P2, P3).

Abstract: Radio system resource management is provided in a cellular radio communication network like a multiple-carrier network. Information is transmitted on at least one frequency range consisting of a plurality of sub-carriers. The sub-carriers of the frequency range are temporarily made available to each cellular radio for transmitting information. The sub-carriers of the frequency range are temporarily assigned to a given number of cellular radios in such a way that each assigned sub-carrier is made available to a set of the cellular radios for information transmission. In the transmission framework, the assignment of information necessary for a transmission decision reduces the signalling complexity to a single symbol OFDM, thereby reducing interferences and increasing spectrum efficiency.

Abstract: A method transmits data by radio during which a frequency band is split into a plurality of subcarriers, and a plurality of antennas are used for transmitting. The data are split into a number of elements, which are to be respectively transmitted by each antenna, said number of elements corresponding to the number of subcarriers, whereby for each antenna, each element is respectively assigned to a subcarrier for transmitting, and at least two antennas on at least one subcarrier transmit different elements. Before an OFDM modulation for each antenna, each element is multiplied by an antenna-specific and element-specific factor. Alternatively, after an OFDM modulation for at least one antenna, the time sequence of the time-dependent signal generated on the basis of the OFDM modulation is reordered. A transmitter carries out the method.

Abstract: In a communication system, a first transmitting station transmits a transmission signal to a first receiving station for transmitting a sequence of data via a radio interface. The radio interface is monitored with respect to an interference signal from an interference source prior to transmission via at least one of the first transmitting station and the first receiving station. The transmission only begins if the radio interface is sufficiently free from interference for a moment in time.

Abstract: A method for the code-modulated transmission of information in a communications system via a carrier having at least two independent orthogonal resources, uses in particular a frequency band with a plurality of sub-resources as the first resource and the time as the second resource with a sequence of time slots constituting the sub-resource. A code of coded data or information in the form of a two-dimensional matrix is used to assign the information to the individual resources, said matrix having a rank that is greater than or equal to 2. A unique mapping of the code elements to the symbols of an OFDM transmission system is carried out in such a way that transmission errors in both the first sub-resource and the second sub-resource can be reconstructed on the receiver side.
