Abstract: There is provided an apparatus, said apparatus including means for receiving, at a central unit of a base station, a measurement report from at least one user equipment receiving multicast traffic from a first distributed unit, wherein the measurement report includes at least one cell controlled by a second distributed unit and configuring, based on the measurement report, at least the first distributed unit and the second distributed unit with data transmission parameters for performing multi-cell point to multipoint transmission of multicast traffic.

Abstract: Various communication systems, such as radio access networks, may benefit from various error correction techniques. For example, certain communication systems may benefit from quality of service driven receiver selective hybrid automatic repeat request for point-to-multipoint communication. A method can include identifying, at a receiver, at least one quality of service threshold. The method can also include identifying, at the receiver, at least one quality of service. The method can further include determining, at the receiver, whether or what kind of feedback is to be used for an erroneously received transport block based on the identified at least one quality of service threshold and the identified at least one quality of service. The method can additionally include communicating, by the receiver, with a transmitter of the erroneously received transport block based on the determination.

Abstract: Embodiments of the present disclosure provide methods, apparatus and computer program products for providing broadcast/multicast services. A method at least partially implemented at an application server comprises transmitting a resource request message to a first broadcast/multicast control node (BM-CN), requesting an allocation of broadcast resource for delivering a multimedia broadcast/multicast service (MBMS) user service; transmitting a further resource request message to a second BM-CN, requesting a further allocation of broadcast resource for delivering the MBMS user service; receiving a first response message from the first BM-CN and a second response message from the second BM-CN, the first response message indicating a first broadcast resource allocated by the first BM-CN for the MBMS user service, and the second response message indicating a second broadcast resource allocated by the second BM-CN for the MBMS user service; and indicating information about the second broadcast resource to the first BM-CN and/or indicating information about the first broadcast resource to the second BM-CN. Methods at the BM-CN and a RAN network node, and corresponding apparatus are also provided.
