摘要： A method for space-time-frequency coding pieces of data includes receiving a stream of a plurality of pieces of data in a multi-antenna transmission system, where the data may comprise a stream of orthogonal frequency division multiple access (OFDMA) symbols, orthogonal frequency division multiplexed (OFDM) symbols or the like. The pieces of data are then coded across space, time and frequency dimensions based upon a plurality of space-time-frequency (STF) codes. The pieces of data are coded such that one or more STF codes in the frequency dimension differ from one or more other STF codes in the frequency dimension. In this regard, the frequency dimension can include a plurality of frequency bins such that the pieces of data can be coded in a manner whereby the plurality of STF codes sequentially circulates through sets of at least one frequency bin in the frequency domain.

摘要： Apparatus, methods and computer program products implement a channel-aware approach for controlling a relay network operative in a wireless communications system wherein weighting matrices are used at a MIMO-capable source electronic device and at the relays where at least one of the weighting matrices is selected or derived using knowledge of channel components of at least one channel link, where the channel link may be from the relays to the destination antennas of the destination device; or from source antennas of the MIMO-capable source device to the relays, or from the source antennas of the MIMO-capable source device to the destination antennas of the destination device. In one approach weighting matrices applied at the source and relay nodes are selected from a predetermined codebook of weighting matrices in dependence on monitored channel conditions. Alternatively, the weighting matrices may be determined using an eigenvalue decomposition and power allocation (e.g., water-filling) approach by using the effective channel correlation matrix possibly combined with the use of the noise correlation matrix.

摘要： The invention relates to a method for controlling the weighting of a data signal in the at least two antenna elements of a multi-element transceiver 1 of a telecommunications network, which data signal is to be transmitted by at least one weighting vector from the transceiver 1 to a terminal 2. For improving such a method, the invention comprises: receiving signals transmitted by the transceiver 1 at the terminal 2; determining for each antenna element a value w(i) indicative of the short term variations; transmitting the values w(i) to the transceiver 1; estimating, based on those values w(i), coefficients e(i) indicative of the stationary structure of the received signals; and weighting the data signal S in the antenna elements with the coefficients e(i). Alternatively, such coefficients e(i) are determined already in the user equipment 2 and transmitted in bursts to the transceiver 1 for controlling the distribution of a data signal to the antenna elements. Similar methods are proposed for soft handover.

摘要： The invention relates to a method for improving the performance of data transmissions over a communications channel, wherein data is coded and modulated for transmission, wherein coding the data results in differently coded bits. In order to allow for a simple way of a more flexible coding, it is proposed that the differently coded bits are mapped for modulation to different modulation symbols of a symbol alphabet, to which modulation symbols different relative reliabilities are assigned, and wherein by mapping the coded bits to the modulated symbols, different reliabilities are associated to differently coded bits depending on the conditions on the communications channel. The invention equally relates to a corresponding communications system and to elements of such a communications system.

摘要： In mobile communications systems transmission antenna diversity is used e.g. to compensate for fading caused to the signal on the radio path. It is known to make the choice of transmission antenna jointly for all subscriber connections, but it is not hereby possible to offer the optimum transmission antenna to simultaneous connections. The present invention aims at a method for implementing transmission antenna diversity on a data transmission connection, which is set up between a transmitting unit (BS), wherein there are several transmission antenna routes (ANT1, ANT2, ANT3), and a receiving unit (MS1, MS2). In the method, a broadcast signal is transmitted through all transmission antenna routes (ANT1, ANT2, ANT3) of the transmitting unit, with the aid of these signals a choice is made in the receiving unit (MS1, MS2) of the optimum transmission antenna route and a message of the choice is transmitted to the transmitting unit (BS), which transmits user data through the transmission antenna route connected for use. According to the invention, the method is characterised in that the broadcast signal of each transmission antenna route is shaped by an individual signal shaping method which is different from the others and a transmission antenna route is connected for use based on the received antenna choice message, individually for each receiving unit.

摘要： A closed-loop signalling method controls multiple transmit beams. The method also includes transmitting a plurality of beams from a first transceiver via a plurality of transmission channels to a second transceiver, evaluating, at the second transceiver, characteristics of the plurality of transmitted beams received at the second transceiver. The method also includes deriving, at the second transceiver, beamforming information for being fed back from the second transceiver to the first transceiver based on the evaluated characteristics. The beamforming information is usable for controlling, at the first transceiver, the transmitting of the plurality of beams. The method also includes selecting, at the second transceiver, at least one set of beamforming information for being fed back from the second transceiver via a feedback path to the first transceiver. The method also includes calculating, at the first transceiver, additional beamforming information which was not contained in the feedback path, based on the beamforming information being fed back.
