    Abstract: The present invention relates to a method for determining link adaptation parameters for a wireless device. The method is performed in a first radio network node of a wireless communication system. The first radio network node hosts a first cell serving the wireless device. The wireless device is interfered by a second cell. The method comprises predicting (410) a future position of the wireless device. The method also comprises estimating (420) a first radio channel quality value for the wireless device in the predicted future position, based on: pathloss values related to the wireless device in the predicted future position for the first and the second cell respectively; and a transmission power of the second cell. The method further comprises determining (430) link adaptation parameters for the scheduling of the wireless device in the future position using the estimated first radio channel quality value.

    Abstract: The present disclosure relates to a link adaptation scheme. In one embodiment, there provides a method for performing link adaptation in an uplink subframe for a first cell, the method comprising: obtaining interference to the uplink subframe of the first cell from at least one neighboring cell's downlink subframe occupying a time interval same as the uplink subframe; determining whether the obtained interference exceeds a predetermined threshold; and applying to the uplink subframe a first link adaptation loop when the obtained interference exceeds the predetermined threshold.

    Abstract: A first base station (14) in a wireless communication system (10) operating according to a synchronised time division scheme detects interference of uplink communication, determines the delay of the interference in relation to an own communication structure (CS1), detects aerial interface identifying data of the source of interference identifying a further base station and sends an indication of the further base station interfering uplink communication to the interference handling node (22). The indication is accompanied by identification data comprising aerial interface identifying data of the further base station and distance data determining the distance (D1) between the first and the further base station. The interference handling node (37) receives the indication with accompanying identification data, investigates the identification data in order to determine the identity of a candidate for the further base station and orders the candidate base station to perform an interference limitation activity.

    Abstract: The present invention discloses a node for transmission mode switching for downlink transmission in a downlink channel (100), comprising: a configuring unit (110) adapted to configure an initial transmission mode for the downlink transmission as a default transmission mode; a deriving unit (120) adapted to derive channel quality metric (CQM) of the downlink channel; a first determining unit (130) adapted to determine a first predefined threshold on the basis of link level simulation of a first transmission mode and a second transmission mode; and a first switching unit (140) adapted to switch the transmission mode from the initial transmission mode to the first transmission mode or the second transmission mode on the basis of the CQM and the first predefined threshold. The present invention provides a simple, direct and efficient approach for transmission mode switching for downlink transmission in a downlink channel on the basis of available feedback from UE (or other kinds of terminals if appropriate) and/or link adaptation decisions from eNB (or other kinds of base stations if appropriate), provides high peak rate while maintaining cell coverage, and provides a proprietary solution without any impact on protocol/standard or UE implementation.
