摘要： Methods and radio network nodes (BS1, BS2) for alleviating interference on downlink radio signals in a victim User Equipment, UE (T1, T2), caused by uplink transmission from an aggressor UE (T2, T1). The interference occurs during a flexible subframe in which the direction of signal transmission is variable between uplink and downlink in different radio frames. A first radio network node (BS1) detects (4:1) that a first UE (T1) that is served by the first radio network node (BS1) is one of the victim and aggressor UEs. The first radio network node (BS1) identifies (4:2) a second radio network node (BS2) employing a subframe scheme such that uplink transmission from the aggressor UE may overlap at least partly with downlink reception in the victim UE during the flexible subframe. The first radio network node (BS1) sends (4:3) a notification to the second radio network node, indicating that the first UE is served by the first radio network node. The second radio network node (BS2) is thereby triggered to execute (4:5) an interference mitigation action for alleviating the interference when serving a second UE (T2) being the other one of the victim and aggressor UEs.

摘要： Techniques are disclosed for synchronizing frequency among a cluster of coordinated transmission points cooperating in a coherent joint transmission. In some embodiments, one transmission point is set (510) as a reference transmission point for a group of coordinated transmission points. Each of one or more other transmission points in the group receives (530) a specified downlink reference signal from the reference transmission point, measures (540) its frequency offset relative to the reference point, and compensates (550) the frequency offset in baseband processing or by a radio adjustment. Which transmission point acts as the reference transmission point is statically defined, in some embodiments, or dynamically configured, in others. Likewise, which time‐frequency resources are used for the reference signal may be statically defined or dynamically configured. In some embodiments, information identifying the reference transmission point and/or specifying the radio resource locations and durations of the reference signal is distributed to the synchronizing transmission points.
