    摘要： A method of coordinated scheduling of a downlink transmission flow from a first radio network node to a user equipment UE in a second radio network node. The method includes scheduling the downlink transmission flow so that the in-sequence delivery of the received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node. The method may further include estimating one or more buffer-related parameters based on buffered data for the downlink transmission flow from the first radio network node, and determining, based on the estimated one or more buffer-related parameter and/or one or more parameters associated with the operation status of the second radio network node, if the in-sequence delivery of the received data blocks to higher layers can be in an acceptable level in the UE.

    摘要： Method and arrangement in a user equipment for adjusting signals transmitted in uplink to a network node based on a feedback value received from the network node. The method includes transmitting a signal, to be received by the network node. A feedback signal is received from the network node, providing feedback on the transmitted signal. A value of a time delay of the received feedback signal is obtained. Signals transmitted in the uplink are adjusted according to the received feedback signal to compensate for the obtained time delay value of the received feedback signal. Related methods and arrangements in a network node are presented.

    摘要： In a radio network in which multiple base stations can communicate with multiple user terminals in a coordinated way, user terminals may be grouped into groups, each group representing a coordination scheme to be used for user terminals in the group. The groups may be chosen, for example, according to path loss or QoS requirements Preferably there are three groups requiring no coordination, multiuser coherent coordination and single user coherent coordination respectively. Grouping may be done dynamically according to one or more of the following factors: —the terminal's signalling overhead—the affordable processing complexity—the traffic load—the radio conditions. The grouping unit may be placed in one or more base stations or in any other suitable unit in the network.
