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.
