摘要： Methods and apparatus for signaling scheduling information in a spatial multiplexing wireless communications system (700), as well as corresponding methods and apparatus for processing such signaling information, are disclosed. An exemplary method for signaling scheduling information comprises scheduling (310, 420) first and second transport blocks (110) for simultaneous transmission during a first transmission interval on first and second data substreams, respectively, and further comprises assigning (320, 430) a single re-transmission process identifier for the first transmission interval and transmitting(330, 440) first scheduling information for the first transmission interval. The first scheduling information comprises the re-transmission process identifier and first disambiguation data. The method further comprises scheduling (360, 470) at least one of the first and second transport blocks (110) for re-transmission during a second transmission interval and transmitting (370, 495) second scheduling information for the second transmission interval, the second scheduling information comprising the re-transmission process identifier and second disambiguation data. The first and second disambiguation data indicate whether the re-transmission of the retransmitted transport block (110) is scheduled for the first or second data substream and may be used by a receiver to determine the same.

摘要： A method and a radio network node for assisting in a handover of a user equipment from a first cell to a second cell as well as a method and a user equipment for handling the handover are disclosed. The radio network node sends an indication to the user equipment, wherein the indication indicates whether or not to use a same first codebook subset restriction bitmap in the second cell as in the first cell. Moreover, the user equipment receives the indication from the radio network node.

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： The disclosure relates to a method, performed in a multi-antenna radio access node comprising four logical antenna ports mapped to corresponding physical antennas, of transmitting data using three physical antennas. The method comprises determining (S51) loss of data transmission from one physical antenna of the four physical antennas. A required multi-antenna transmission scheme is determined (S52). An antenna mapping matrix prestored in the radio access node is selected (S53), the selected antenna mapping matrix adapted to the required multi-antenna transmission scheme. Data on the four logical antenna ports are re-mapped (S54) to the remaining three physical antennas by using the selected antenna mapping matrix, whereupon the data is transmitted (S55) from the remaining three physical antennas.

摘要： There is provided a dual-polarized N/2-column antenna arrangement. The antenna module arrangement comprises a coupler module. The coupler module is arranged to direct a first summation of energy from signals from a first distinct set of power amplifiers of an N-channel radio to a first single output port connected to a first polarization of a first column of the dual-polarized N/2-column antenna arrangement. The coupler module is arranged to direct a second summation of energy from signals from a second distinct set of power amplifiers of the N-channel radio to a second single output port connected to a second polarization of a second column of the dual-polarized N/2-column antenna arrangement.
