摘要： A transmitter for transmitting data in a cellular radio system is provided. The transmitter transmits data to User Equipment(s) using multiple transmitting antennas, using at least two polarization formers generating orthogonal polarizations of an input data stream. The transmitter further comprises a transmitter diversity arrangement adapted to receive input data to be transmitted to the User Equipment(s), where the transmitter diversity arrangement is connected to the input terminals of the polarization formers. By combining transmitter diversity with polarization former weights, orthogonality between multiple, in particular 4, transmitting antennas can be obtained.

摘要： A radio base station has at least two radio chains and a precoder for precoding information symbols by a precoding matrix for multi-antenna transmission to a number of user equipment terminals. Precoding matrix statistics representative of phase coherency between at least two radio chains is compiled based on feedback information representative of preferred precoding matrix from one or more user equipment terminals (S1). A relative phase error is then detected between radio chains based on the compiled precoding matrix statistics (S2). It is then possible to compensate or otherwise adjust for the detected relative phase error (S3) based on the compiled precoding matrix statistics.

摘要： Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, it is assumed that a mobile unit is served by an active cell set (S1). A basic idea according to the present invention is to select, prior to establishment of a new serving radio link for a mobile unit, a narrow target beam within a neighbor area of the current active cell set of the mobile unit based on pre-established information of narrow beams within the neighbor area (S2), and to initiate establishment of the new serving radio link directly with the selected narrow target beam (S3). In this way, the narrow target beam can be selected at handover initiation and the new radio link can be established directly with a target narrow beam without first establishing the radio link with a cell-wide beam and then, after uplink measurements, reconfiguring the radio link onto a narrow beam.

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.
