摘要:
A method for transmitting data within a mobile telecommunication system from a user equipment having at least two transmit antennas to a base station having at least two receive antennas. The method comprises (a) providing a number of data streams at the user equipment, wherein the number of data streams is smaller than the number of transmit antennas, (b) applying a spatial pre-coding to the data streams, and (c) transmitting the spatially pre-coded data streams to the base station via the transmit antennas, wherein the number of transmit antennas used for transmitting the spatially pre-coded data streams is larger than the number of data streams. A corresponding method for receiving data, a user equipment for carrying out the data transmitting method, a base station for carrying out the data receiving method and a computer program for controlling the described data transmitting and/or receiving method.

It is described a method for compensating interference effects within a telecommunication network including at least a first base station and a second base station, which serve in a cooperative manner a first user equipment and a second user equipment by using time division duplex. The method is applied in an operational state, in which the first base station is in a downlink mode and the second base station is in an uplink mode. The method includes (a) determining at least one of a first channel state information between the first base station and the second base station and a second channel state information between the first user equipment and the second user equipment, (b) encoding data signals based on the first and/or the second channel state information, and (c) transmitting the encoded data signals by the first base station and/or by the second base station. It is further described a telecommunication network, a program element and a computer readable medium, which are adapted to carry out or control the described method.

Method for transmitting data in a Multiple-Input Multiple-Output (MIMO) system and communication system for transmitting data in a MIMO system. A method for transmitting data in a communication system is provided. The method includes the steps of selecting a first channel (C1) and a second channel (C2), of receiving by the second receiver (Rx2) of first data and frequency resource information, of performing a non-linear pre-coding for second data (D2) of the second channel (x2) and of sending the precoded second data (D2) from the second transmitter (Tx2) to the second receiver (Rx2) and sending the first non-pre-coded data (D1) of the first channel (C1) from a first transmitter (Tx1) to a first receiver (Rx1) at the same timeframe.

摘要:
One exemplary aspect of the invention provides a routing node for an FDD communication network, which node has a node receiving apparatus, which is set up in such a manner that it can be used to receive signals from a terminal at a first frequency, and a node transmitting apparatus which is set up in such a manner that it can be used to transmit signals to the terminal at a second frequency. In this case, the routing node is set up in such a manner that it can transmit an indication signal to the terminal, which signal indicates whether the routing node can receive signals at the first frequency at a given point in time.
