摘要： The present invention relates to a method and a communication system wherein stations communicate on a wireless interface. The method includes the steps of including beam identity information into signals transmitted on multiple beams provided by a first station, receiving at a second station signals transmitted from the first station, and identifying beams via which the second station received signals from the first station based on said identity information. At least one beam for transmission on the wireless interface between the stations is then selected. A station configured for the communication comprises antenna means for receiving signals transmitted from the other station on multiple beams and a controller for identifying beams based on beam identity information associated with signals received from the other station.

摘要： The invention relates to a radio system and a data mission method. In the method of the invention, a transmitter codes a signal to be transmitted such that at least two non-orthogonal channels are obtained; the transmitter transmits the coded channels via at least two different transmit antenna paths; and a receiver receives the signal. The transmit antenna paths are divided into at least two different groups; and the signals to be transmitted through the different groups are weighted in the transmitter by means of changeable weighting coefficients determined for each group.

摘要： The invention relates to a method and an arrangement for transmitting a digital signal consisting of symbols, which arrangement comprises a coder (308) for coding complex symbols to channel symbols in blocks having the length of a given K, means (312) for transmitting the channel symbols via several different channels and two or more antennas (314 to 318). The coder (308) is arranged to code the symbols using a code matrix, which can be expressed as a sum of 2K elements, in which each element is a product of a symbol or symbol complex conjugate to be transmitted and a N×N representation matrix of a complexified anti-commutator algebra, extended by a unit element, and in which each matrix is used at most once in the formation of the code matrix. A code matrix is also provided which is formed by matrices of a portion of the symbols placed on the diagonal of the code matrix and by matrices of a second portion of symbols along the anti-diagonal of the code matrix.

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： Apparatus, and an associated method, for facilitating communication of communication data upon a communication channel susceptible to distortion. Both diversity techniques and spatial multiplexing techniques are utilized to compensate for the distortion introduced upon the data during its communication. Separate parts of the communication data are mapped pursuant to separate mapping schemes. The mapping schemes are selected to exhibit different properties. When the communication data is communicated upon the communication channel and delivered to a receiving station, a decoder decodes the data to recover the informational content of the data.

摘要： A transmitter and an applicable method comprising 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 is disclosed. 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.
