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： A method for limiting Channel Quality Indicator (CQI) reporting from a User Equipment to a network node is provided where a User Equipment can transmit CQI reports to a network node, such as e.g. a base station, when the User Equipment is operating in low transmission and/or low reception activity mode. A limited CQI reporting is obtained by triggering the reporting according to one or more predefined rules, which to at least some extent depend on CQI specific information provided to the User Equipment from the network node. A User Equipment and a network node adapted to operate in accordance with the suggested method are also provided.

摘要： When a handover is to be performed of a user equipment from a serving radio base station to a target radio base station, it is ensured before the handover that the user equipment is operating in a MIMO mode that is supported by the serving radio base station and by the target radio base station. This can be done by comparing a first mode list, which includes potential MIMO modes jointly supported by the user equipment and the serving radio base station, and a second mode list, which includes potential MIMO modes jointly supported by the user equipment and the target radio base station, to form a common mode list.

摘要： The invention relates to a method of globally balancing the transmit power in a cellular radio system with tight reuse of frequencies, to a central controller node, and to an access point that in combination with conventional power control schemes balances the downlink transmission power on reused frequencies in order to balance co-channel interference in a multi-cell environment. The power balancing scheme dynamically assigns a token to or takes a token away from an individual reused radio channel based on quality of, or based on transmission power in the channel. A token, if taken away from the channel, inhibits conventional power control thereby freezing the transmission power in the channel on its current power level. A token, if assigned or re-assigned to channel, re-assumes conventional power control thereby allowing dynamic variation of the transmission power in the channel in accordance with the conventional power control.
