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 first radio connection unit of a radio communications system, which data signal is to be distributed for parallel transmission to a second radio connection unit to at least two beams. In order to improved such a method, it comprises: determining in the second radio connection unit a weight information enabling the first radio connection unit to determine the sets of weights for suitable beams for transmission and transmitting it to the first radio connection unit; and distributing the data signal in the first radio connection unit to those sets of weights and transmitting the data signals simultaneously via the formed beams. Alternatively or additionally, the second unit determines the number of beams to be used and informs the first unit about it. The invention equally relates to corresponding radio connection units, radio connection unit modules and radio communications systems.

摘要： A method, device, and system in which radio links between relays and users are optimized separately from the links between relays and base stations and in which multiple simultaneous data streams between relays and base stations are created. The system includes transceivers of at least three kinds with two kinds of radio interfaces. The first kind of transceiver, a base station (BS), is connected to the core network with a link of wire line quality. The second kind, a relay station (RS), is connected to the BS with a first radio interface, and to the third kind, the user equipment (UE), with a second radio interface. The first and second radio interfaces can operate, at least in part, using the same frequency bandwidth. The UE can also connect directly to the BS using the second radio interface if the BS is closer than any RS.

摘要： The invention is related to a computer program product encoding a computer program of instructions for executing a computer process for interference control, the process comprising: setting a first power constraint for multi-antenna transmissions; setting a second power constraint for single-stream transmissions, wherein the first power constraint and the second power constraint control the use of predetermined resources in a way that the resources are reserved for the single-stream transmissions or the resources are allowed for the multi-antenna transmissions and for the single-stream transmissions, the power level of the multi-antenna transmissions being lower than the power level of the single-antenna transmissions.

摘要： The performance and symbol rate in a wireless mobile system are increased by forming a transmission code matrix using transformed orthogonal codes, in such a way that the code is robust to channel statistics and operates well in both Ricean and (correlated) Rayleigh channels. Furthermore, the invention enables high symbol rate transmission using multiple transmit antennas, and one or multiple receive antennas, and obtains simultaneously high diversity order and high symbol or data rate.

摘要： A transmitter and an applicable method include an antenna system for achieving two transmit paths, a first modulator for modulating a signal to be transmitted into complex modulation symbols, and a second modulator for constructing layered channel symbols as linear combinations of the complex modulation symbols. The second modulator constructs channel symbols by using first and second non-zero coefficients when performing the linear combination. The ratio of the first and second coefficients is not a real number. The channel symbols are transmitted by using a first non-zero total power for transmission on a first transmit path, and a second non-zero total power for transmission on a second transmit path, wherein the first and second total powers are not equal.
