摘要： The disclosure relates to methods and apparatuses that allow for channelisation code allocation adapted for uplink MIMO transmissions. A method for use in a user equipment of a telecommunication system comprises spreading data symbols of a plurality of streams to be transmitted from the user equipment as MIMO transmissions. The step of spreading the data symbols comprises allocating, for each stream, at least one channelisation code (62) to be applied for spreading the data symbols of the stream. The plurality of streams are allocated channelisation codes (62) from a predefined code tree (61) of applicable channelisation codes such that any channelisation code (62) is allocated to more than one stream only if there is no applicable channelisation code left in the code tree (61) which currently is not allocated for any stream. The channelisation code allocation scheme makes it possible to avoid inter- stream interference in many scenarios of uplink MIMO transmissions.

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.
