摘要： Embodiments herein relate to a first communication device (122, 124) and method therein for enabling interference management of data transmissions from a second communication device (110) to a third communication device (121) in a wireless communications network (100). Furthermore, embodiments herein also relates to a second communication device (110) and method therein for enabling interference management of data transmissions from the second communication device (110) to a third communication device (121) in a wireless communications network (100). First, the second communication device (110) transmits information relating to a request for a first set of radio resources of a radio channel for a first data transmission to the third communication device (121). Then, this information relating to a request for radio resources of a radio channel for a first data transmission from the second communication device (110) to the third communication device (121) is received by the first communication device (122, 124). In response thereto, the first communication device (122, 124) transmits an interference notification to the second communication device (110) when the received information relating to a request for radio resources of the radio channel is determined to conflict with requested radio resources of the radio channel for a second data transmission to or from the first communication device (122, 124). Thus, the second communication device (110) receives at least one interference notification from at least one first communication device (122, 124) indicating that its transmitted information relating to a request for radio resources of the radio channel has been determined to conflict with requested radio resources of the radio channel for at least one second data transmission to or from the at least one first communication device (122, 124).

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.

摘要： The embodiments relate to a method and a base station (110) for interference management in a cellular network (100) employing Space-Division uplink (UL) downlink (DL) Duplexing (SDD). The base station (110) assigns a plurality of Remote Radio Units (RRU) as Tx RRUs operable to dedicatedly transmit downlink signals to a plurality of UEs and Rx RRUs operable to dedicatedly receive uplink signals from the plurality of UEs at the same frequency band and same time as the transmission of the Tx RRUs. The base station then suppresses the interference caused by simultaneous transmission on the same frequency band by using a Tx spatial beamforming weighting matrix and a Rx spatial beamforming weighting matrix. In addition, the base station may perform cross-talk cancellation on the residual interference contained in the received signals by using the knowledge of the downlink traffic data.
