Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for multicasting traffic using multi-connectivity. A wireless network can send a downlink (DL) packet, which follows one path from a core network entity to a user equipment (UE) under current standards, to multiple base stations (BSs) and from each of the base stations to a UE. The UE receives the DL packet from whichever BS first delivers the DL packet, and then the UE sends a report reporting receipt of the DL packet back to all of the BSs. BSs that receive a report indicating the UE received the packet can drop the packet, even if they have not yet successfully delivered the packet. The same procedure can be used for an UL packet, which can be sent from a UE to multiple BSs, and from the BSs to a core network entity.
