摘要： A method in a first base station (105) for handling a downlink transmission is provided. The first base station (105) serves a first user equipment (120). The first base station (105) defines a subframe in which the first base station (105) is to avoid interfering a downlink radio channel between a second base station (115) and a second user equipment (125). The second user equipment (125) is located in an extended range of the second base station (120). The first base station (105) performs, in the defined subframe, a downlink transmission to the first user equipment (120). The first base station (105) receives, from the second base station (115), an indication of an interference caused by the performed downlink transmission on the downlink radio channel. The first base station (105) adjusts a further downlink transmission to be performed by the first base station (105) based on the indication.

摘要： The invention relates to a method for detecting that an additional serving cell is activated is provided. The method is implemented by a wireless device and a network node of a system supporting carrier aggregation. The network node serves the wireless device configured with a first serving cell and the additional serving cell. The network node method comprises configuring (710) the wireless device to transmit feedback information associated with the additional serving cell at a first rate, and transmitting (520) a command to the wireless device to activate the additional serving cell. The method also comprises detecting (530) the activation of the additional serving cell based on reception of feedback information from the wireless device, and configuring (540) the wireless device to transmit feedback information associated with the additional serving cell at a second rate after activation, where the second rate is lower than the first rate.

摘要： An interference problem for UE retransmissions at the end of a Sequence Frame Number pattern, in a system wherein a macro base station (12) employs Almost Blank Subframes (ABS) to avoid interference with a micro base station (16), is avoided by first recognizing that an ABS pattern will reset at the end of a SFN period. In some embodiments, in response to this recognition, the micro base station (16) may command (108) a UE to alter a transmission to the micro base station (12), to improve the probability of accurate reception - such as by increasing its transmit power during the relevant time slots, or utilizing a more robust data correction encoding scheme. In other embodiments, in response to recognizing the change in the ABS pattern, the macro base station (12) may schedule (208) other UE to a PRB where they cause lower interference, or may avoid scheduling macro cell UEs in the same time slot.
