    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.
