    摘要: A first radio network node (110) and a method therein for measuring interference as well as a second radio network node (120) and a method therein for enabling the first radio network node to measure interference are disclosed. The first radio network node (110) obtains (201) configuration information for indicating a designated subframe in which a reference signal for measurement of the interference is to be transmitted by the second radio network node (120). The second radio network node (120) obtains (202) configuration information for configuring a designed subframe for transmission of a reference signal. The first radio network node (110) receives (205), in the designated subframe indicated by the configuration information, the reference signal transmitted by the second radio network node (120). The first radio network node (110) determines (206) a value of the interference based on the reference signal.

    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.
