摘要： According to the invention a mobile station (10) obtains the time delays of transmissions (T0, T1, T2) from a set of base stations in reaching the mobile station, determines a difference (t1, t2 ) between a group of the time delays and a reference time delay and transmits the time delay differences to base stations (14, 16) in the set having transmissions with time delays in the group via at least one link that is specific to the mobile station. A base station (14) receives the difference (t1) between its own transmission time delay and the reference time delay, compares the difference with a time range and corrects the timing of its transmissions if the difference is outside of the time range.

摘要： The present invention discloses a method, an apparatus and a system for calibrating antenna, wherein channel transfer functions are obtained for subcarriers on at least one antenna to be calibrated and on a reference antenna, and the obtained channel transfer function of a first subcarrier is filtered by multiplying a symmetry filter with channel transfer functions of said first carrier's neighboring subcarriers, and the filtered channel transfer function is normalized; and a signal carried by the first subcarrier on the antenna to be calibrated is multiplied with the ratio of the filtered and normalized channel transfer function of the first subcarrier on said reference antenna to the filtered and normalized channel transfer function of said first subcarrier to get compensated. This enables to perform joint compensation on a subcarrier basis and thus reduce computation complexity.

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.
