    摘要： The disclosure relates to methods and apparatuses that allow for channelization 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 channelization code (62) to be applied for spreading the data symbols of the stream. The plurality of streams are allocated channelization codes (62) from a predefined code tree (61) of applicable channelization codes such that any channelization code (62) is allocated to more than one stream only if there is no applicable channelization code left in the code tree (61) which currently is not allocated for any stream. The channelization code allocation scheme makes it possible to avoid inter-stream interference in many scenarios of uplink MIMO transmissions.

The system includes a first filter to filter uplink TDM transmissions, associated with the user device, during a first period of time when the user device is transmitting on an uplink data channel (DCH) to generate a first interference estimate. The system further includes a second filter to filter uplink TDM transmissions, associated with the user device, during a second period of time when the user device is not transmitting on the uplink DCH to generate a second interference estimate. The system also includes a third filter to filter uplink TDM transmissions, associated with the user device, during the first and second periods of time, to generate a third interference estimate. The system further includes a power control unit to determine one or more power control commands for sending to the user device based on the first, second and third interference estimates.
