  • Patent number: 8081689
    Abstract: The invention concerns a method for performing frequency selective control channel scheduling in networks using an OFDM spectrum, whereby a base station (BS1-BS8) broadcasts on at least one predefined subcarrier which is known to all mobile terminals (T1-T4) a signaling information common to all mobile terminals (T1-T4) indicating the position of at least one subcarrier of at least one frequency selective shared control channel and at least one identification of at least one addressed mobile terminal, the base station (BS1-BS8) sends signaling information for said at least one addressed mobile terminal at the indicated position of said at least one subcarrier of said at least one frequency selective shared control channel, and at least one mobile terminal (T1-T4) measures at least one subcarrier of said at least one frequency selective shared control channel for channel quality estimation, a base station (BS1-BS8), a mobile terminal (T1-T4) and a network (CN) therefor.

  • Publication number: 20110235606
    Abstract: The invention relates to a method for resource allocation in a radio communication system (RCS). The radio communication system (RCS) comprises a base station (BS) and at least one mobile station (MS1, MS2). The base station (BS) comprises a first antenna system (AS1) with at least two antenna elements (AE1, AE2). The base station (BS) and the at least one mobile station (MS1, MS2) comprise a codebook.

  • Patent number: 7675894
    Abstract: The present invention relates to a method for gaining channel quality information at a base station of a multi-carrier radio communication system having a plurality of orthogonal frequency sub-carriers. According to the present invention, the method comprises the steps of: measuring a Channel Frequency Response at a user terminal of said multi-carrier radio communication channel; extracting samples of said Channel Frequency Response represented in the frequency domain at a predefined oversampling factor; sending said samples on a signaling channel from said user terminal to said base station; performing a windowing operation on the received samples in the time domain; determining a channel quality information for each of said sub-carriers on a representation in the frequency domain of said received samples after windowing operation.

  • Patent number: 7545763
    Abstract: The present invention relates to a method for sending channel quality information in a multi-carrier radio communication system comprising at least one mobile terminal and at least one base station, said channel quality information being sent on a signaling channel by said mobile terminal to said base station.

  • Patent number: 7366520
    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.
