摘要： A method is disclosed for a network node of a cellular communication network adapted for application of an uplink triggered cell handover functionality. The uplink triggered cell handover functionality may comprise initiating a handover when it is determined that an uplink channel performance metric relating to a serving cell falls on a first side of (e.g. is lower than) an uplink handover threshold. The method comprises dynamically restricting application of the uplink triggered cell handover functionality based on whether a restriction criterion is met or not. The restriction criterion is based on at least one of a resource cost of the uplink triggered cell handover functionality and a performance gain of the uplink triggered cell handover functionality. For example, the method may comprise, when the UL triggered cell handover functionality is enabled, disabling the UL triggered cell handover functionality if a disabling criterion is met and, when the UL triggered cell handover functionality is disabled, enabling the UL triggered cell handover functionality if an enabling criterion is met. In some embodiments, restricting application of the uplink triggered cell handover functionality may comprise restricting the application for all wireless communication devices served by the network node. In some embodiments, restricting application of the uplink triggered cell handover functionality may comprise restricting the application for at least one specific wireless communication device served by the network node. Corresponding arrangement, network node and computer program product are also disclosed.

摘要： A network node assigns a transmission parameter, e.g., an Antenna Port Identifier (APID) and a Scrambling Code Identifier (SCID) combination, to each of a plurality of wireless devices responsive to the channel correlations between each pair of wireless devices formed from the plurality of wireless devices, to facilitate the transmission of data from the network node to each wireless device. Such intelligent transmission parameter assignment reduces interference and/or improves throughput.
