摘要： The present invention relates to a method for controlling performance in a radio base station communicating in a Time Division Duplex (TDD) mode in a cellular network. The radio base station has a transceiver comprising a transmitter part, a receiver part, and an antenna, the antenna being alternately connectable to the transmitter part and the receiver part. The method comprises: estimating, at the receiver part, a leakage signal in the receiver part, the leakage signal originating from a local oscillator of the transmitter part; and removing, at the receiver part, the estimated leakage signal from a received uplink signal. The present invention also relates to a corresponding radio base station.

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.

摘要： User grouping is employed to tradeoff the COMP forward link capacity and required reverse link feedback, which makes the design of COMP practical and flexible. A channel element, such as the large scale fading, is measured for each distributed transmitter and UE pair based on reference signals, and the network receives this information as feedback in the reverse link. The COMP determines a maximum cross interference level αreq that is affordable, based on the available reverse link capacity for feedback. If this maximum cross interference level αreq is exceeded, geographically separate UEs are divided into as few groups as possible, with UEs within each group separated, and the groups are allocated different time/frequency resource blocks. The grouping is done with the constraint that the cross interference does not exceed αreq.
