    摘要: The present disclosure relates to a Multimedia Broadcast Multicast Service (MBMS), and in particular to a method, system and network entity for configuring transmission parameters for providing MBMS service(s). In one embodiment, a network entity in communication with a plurality of network nodes within a geographical area is provided. The network entity includes a communication interface configured to receive a representation of signal quality measurement data associated with a plurality of non-Multimedia Broadcast Multicast Service, non-MBMS, user equipments, UEs. Each UE is served by at least one of the plurality network nodes. The network entity includes a processor communicatively coupled to the communication interface. The processor is configured to determine a combined signal quality data of a plurality of MBMS UEs based at least in part on the received representation of signal quality measurement data associated with the plurality of non-MBMS UEs.

    摘要: A node (260) of a cellular network node sends data units to a group of base stations (200). Each data unit is configured for conveying multicast data to be sent by the base stations (200) in a synchronized manner at a starting time indicated in the data unit. For each of the data units, the node (260) determines the starting time as the sum of the time of sending the data unit from the node and an offset value. Further, the node (260) obtains feedback information from the base stations (200) of the group. The feedback information indicates a deviation of the starting time indicated in one of the data units (411) from an earliest possible time of sending the multicast data from the data unit (411) by the base stations (200) of the group. Depending on the feedback information, the node (260) adapts the offset value.

    摘要: A method and device for determining whether to send a measurement report to a serving cell and determining when an inter-cell coordination procedure is likely to achieve coordination gain are disclosed. According to one aspect, a method includes performing received signal quality measurements of the serving cell and a plurality of neighboring cells. The method also includes calculating a UE metric based on the received signal quality measurements of a plurality of interfering cells and based on a scaling parameter. The method further includes comparing the calculated UE metric to a threshold to determine whether to send the measurement report to the serving cell.

    摘要: A method and apparatus for preventing muting of ongoing services when a new multicast traffic channel, MTCH, is to be started or stopped are disclosed. In one embodiment, the method includes sending a multicast control channel, MCCH, update at a start of an MCCH modification period indicating that the new MTCH is to be started during a following MCCH modification period. The method further includes sending a calculated multicast control channel service start offset, MCCH-offset, indicating when the new MTCH is to be started after an MCCH boundary.
