    摘要: Methods and arrangements in a control node, a base station and a UE, for achieving a UE up link transmit diversity mode adaptation, which is coordinated between a base station and a control node. The methods and arrangements involve the control node indicating a set of allowed up link transmit diversity modes to the base station. Further, an up link transmit diversity mode for the mobile terminal is selected in the base station, from amongst the currently allowed up link transmit diversity modes; where the selection is based on information concerning the mobile terminal which is available in the base station. The base station then indicates the selected up link transmit diversity mode to the mobile terminal, which changes to the up link transmit diversity mode indicated by the base station. The methods and arrangements enable a faster and more flexible UE up link transmit diversity mode adaptation.

    摘要: A radio network system employing a method with dynamic adjustment of the power offset that provides a “per-UE”-NACK to ACK power offset calculation method instead of using a fixed offset for all users in the cell is disclosed. Also for each UE, the power offset can adjusted dynamically. The adjustment is based on the error event of NACK to ACK. When an error event of NACK to ACK happens, the offset is increased, otherwise the offset is decreased. Hence, the offset can be controlled for each User Equipment for the duration of a call starting from some standard configured value is calculated and used rather than a fixed offset.

    摘要: In a transmission scheme for transmitting data over a connection connecting a transmitting Main Unit and a receiving Radio Unit of a cellular radio system, where the transmitted data corresponds to user-plane data in the form of digital baseband data for different antenna-carriers, the digital signal is transmitted over the connection, e.g. a fiber, before spreading and combining is provided. The power and weight factor is transmitted separately with a few additional bits. Hereby, the Digital signal before spreading and combining is transmitted in the fiber instead of the combined multi-code signal.
