    摘要: Disclosed herein are apparatus, methods and computer program products providing sub-channel re-assignment performed by a relay node in a wireless communications system. In the apparatus, methods and computer program products, a relay receives an input signal made up of a plurality of sub-channels. The relay de-multiplexes the sub-channels into a plurality of signal streams, and reassigns at least one of the signal streams to a new sub-channel on the output side, the new sub-channel on the output side different from the sub-channel originally containing the signal stream on the input side. In one embodiment of the invention, the wireless communications system is an OFDM system and the sub-channels correspond to OFDM sub-carriers. In another embodiment of the invention, during sub-channel reassignment input sub-channels are matched to output sub-channels sharing a pre-determined criterion.

    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 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.

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: 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.

    摘要: The invention relates to a cellular radio system and a method of locating a terminal in a cellular radio system having in each cell at least one base station 104 communicating with the terminals 100 within its area. The base station measures channel parameters from the signals transmitted by the terminals. The coverage area of each base station is modelled by a digital map. To enable accurate localization of the terminals, to each point on the digital map is added a model of the channel parameters of a signal to be transmitted from the point. The channel parameters estimated from the signal of the terminal are compared with the parameters at different points on the map, and the terminal is located on the basis of the comparison.
