Methods, devices, and systems for processing uplink broadcast or multicast (“broadcast/multicast”) packets from a user equipment (UE) and distributing the broadcast/multicast packets to other UEs in a network. In some aspects, a UE may receive, from a base station, a downlink packet comprising broadcast or multicast (broadcast/multicast) Ethernet data for a protocol data unit (PDU) session of the UE with a data network (DN) associated with the base station, determining whether the downlink packet corresponds to an uplink packet previously transmitted to the base station by the UE, discarding the downlink packet for the PDU session based on determining that the UE previously transmitted the corresponding uplink packet comprising the broadcast/multicast Ethernet data for the PDU session to the base station, and processing the downlink packet for the PDU session based on determining that the UE did not previously transmit the corresponding uplink packet.
