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.

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.
