摘要： The present invention relates to a method and arrangement in a transmitter unit of a multi-antenna system for an improved calculating of the antenna weights for a beamforming transmission of data from a transmitter unit to a target receiver unit, whereby interfering signal components for receiving units other than the target receiving unit and the desired communication signal at a target receiving unit are weighted by receiver-specific parameters describing the receiver capabilities of said units in terms of their capability for interference suppression and/or signal enhancement. The invention also relates to a method and arrangement for scheduling of user equipments by using said information on the signal processing capabilities for received signals of each receiving unit.

摘要： It is presented a method for determining how to prepare transmission signals for transmission. The method is performed in a transmitter device and comprises the steps of: obtaining an indicator of mutual correlation between signals transmitted from different transmission antennas of the transmitter device; when the indicator indicates mutual correlation less than a threshold value, selecting a first transmission signal operation scheme; and when the indicator indicates a mutual correlation greater than the threshold value, selecting a second transmission signal operation scheme.

摘要： A receiving node makes an early estimate of the outcome of a decoding attempt and sends a corresponding early feedback (EHF) to the sending node. This has an effect of enabling a fast retransmission of the data by the sending node in case the decoding by the receiving node is likely to fail. An advantage of this is that any delays due to data retransmission may be minimized, resulting in a higher average throughput of the data transmission between the nodes.

摘要： The invention relates to the technical field of radio communications, and in particular to an antenna device for a radio base station, and a method for precoding data in a Multiple-Input Multiple-Output (MIMO) system. Embodiments of the invention disclose a secondary precoder 24 in series with a multiple-input multiple-output precoder 22. The secondary precoder 24 has a plurality of inputs 34, 36 and a plurality of outputs 38, 40. The second plurality of inputs being in communication with each plurality of outputs 38, 40 such that one or more signals input to a respective one or more of the second plurality of inputs 34, 36 provides a substantially equal power of signals at the second plurality of outputs 38, 40.

摘要： An objective problem of the invention is to provide a mechanism for improving the performance of a radio access network. According to a first aspect of the present invention, the object is achieved by a method in a first node for adapting a multi-antenna transmission to a second node over an effective channel. The first node and the second node are comprised in a wireless communication system. The method comprises the steps of obtaining at least one symbol stream and determining a precoding matrix having a block diagonal structure. The method comprises the further steps of precoding the at least one symbol stream with the determined precoding matrix, and transmitting the at least one precoded symbol stream over the effective channel to the second node.

摘要： The embodiments herein relate to a method in a user equipment for handling CSI in a communication system. The user equipment determines the CSI, based on information about a CPICH. The CSI comprises at least one of a CQI, a RI, a PCI and an HARQ ACK/NACK. The user equipment transmits the CSI multiplexed into a plurality of TTIs to the base station so that a first CQI-S is transmitted in one TTI and a second CQI-S or a DTX codeword is transmitted in another TTI. The second CQI-S corresponds to a second layer.

摘要： The invention relates to devices and methods for signalling control information associated with transmission of data over a wireless channel. A second communication device receives (S2) data from a first communication device, wherein the data comprises an indication of recommended precoders and a recommendation of a first transmission rank to possibly use during transmission. The second communication device determines (S4) a second transmission rank to use for transmitting data, and transmits (S6) a confirmation message to the first communication device. The confirmation message comprises a confirmation that transmission of data from the second communication device is using at least parts of each recommended precoder associated with a frequency resource that falls within the transmission of data and an indicator of the second transmission rank to use.

摘要： In a transmitter using at least two transmitting antennas a STTD transmitter is used in combination with a common pre-coding transmitter for power amplifying power balancing. A selector can be provided for selecting data/channels transmitted using STTD and common pre-coding such that for one channel type, STTD or common pre-coding is used whereas the combination of both STTD and common pre-coding is used for a different data/channel type. By selectively using both STTD and common pre-coding for power amplifier power balancing, an improved power balancing is achieved. At the same time, the STTD gain is obtained in the relevant cases but the STTD loss in other cases is avoided.
