摘要： The invention relates to Coordinated Scheduling for a Time Division Duplex (TDD) network. In a method for User Equipment (UE) scheduling by a base station in a TDD network, the base station receives scheduling decision from at least one neighboring cell of the base station, and schedules a UE among a plurality of UEs in the serving cell of the base station based on the scheduling decision from the at least one neighboring cell and based on smart antenna information. The inter-cell interference is suppressed and therefore the network performance is improved.

摘要： Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

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.
