Abstract: Methods, apparatuses, and computer program products are disclosed for implementing recovery from a communication failure. A method includes receiving, by a first user equipment, an indication that a second user equipment has experienced a failure, where the first user equipment and the second user equipment are part of a same device, and where the first user equipment is configured with a first primary reliability group and where the second user equipment is configured with a second primary reliability group; based upon the indication, the first user equipment transmitting to a network equipment a first signal to activate a secondary reliability group for the first user equipment; and receiving, by the first user equipment, a second signal to use the secondary reliability group, where the second signal is at least partially based upon the first signal transmitted from the first user equipment.

Abstract: A technique includes transmitting a request for the delivery of multicast data; receiving the multicast data via a unicast data radio bearer or a multicast data radio bearer, wherein the user device is located in a first cell; receiving, by the user device from the base station, a connection suspend message, wherein the connection suspend message includes: information describing a radio access network (RAN) multicast area (RMA) for the delivery of the multicast data via a multicast data radio bearer, and a group identifier associated with the multicast data, wherein the RMA includes a list of one or more cells that has been updated by the base station to include the first cell where the user device is located; entering, by the user device, a low activity state in response to the connection suspend message; and, receiving, by the user device, the multicast data via the multicast data radio bearer.

Abstract: A method, apparatus and computer program product receive an application flow comprising a source flow and a supplementary flow from a core network. The method, apparatus and computer program product receive a flow payload indication from the core network. The method, apparatus and computer program product determine whether the application flow is to be transmitted via a unicast transmission or a multicast transmission. The method, apparatus and computer program product determine whether the supplementary flow is droppable based on the flow payload indication and whether the application flow is to be transmitted via a unicast transmission or a multicast transmission. The method, apparatus and computer program product cause only the source flow to be transmitted in a circumstance where the supplementary flow is droppable.

Abstract: Embodiments of the present disclosure relate to time domain resource allocation for multicast broadcast service. A first device receives, from a second device, DCI comprising a TDRA field, and determines, based on at least one of an identifier for scrambling the DCI, a RRC state of the first device or a type of traffic configured for the first device, a TDRA list from a set of configurations for TDRA. Then the first device applies, based on the TDRA list, the TDRA field for reception of the traffic from the second device. In this way, a TDRA list to be used may be determined in an optimal manner, with all terminal devices receiving multicast and broadcast traffic determining common values for time domain resources where data traffic would be scheduled.

Abstract: A method, apparatus and computer program product receive, at a network node of a communication network, information about an accumulated packet delay in the communication network. The method, apparatus and computer program product estimate next hop transport delay and estimate or measure a processing delay of the network node. The method, apparatus and computer program product update the accumulated packet delay by adding the next hop transport delay and the processing delay to the accumulated packet delay. The method, apparatus and computer program product cause transmission of information about the accumulated packet delay in a header of a packet carrying user data or a control packet in the communication network to a next hop node of the communication network.

Abstract: Systems, methods, apparatuses, and computer program products for multicast-broadcast service (MBS) deactivation and/or activation are provided. One method may include receiving, at a multicast-broadcast session management entity, a multicast-broadcast service (MBS) session setup message, from at least one management entity, comprising at least one of an identifier of at least one network node requesting setup of the multicast-broadcast service (MBS) session and an identifier of the at least one management entity. The method may also include storing, at the multicast-broadcast management entity, at least one of the identifier of the at least one network node, the identifier of the at least one management entity, or an identifier of a region of the at least one management entity.

Abstract: Systems, methods, apparatuses, and computer program products for the configuration of user device(s) for reception of point-to-multipoint transmission are provided. One method may include receiving, at a user equipment, a configuration for point-to-multipoint reception of a group-common transport channel. The configuration may include a group-common signaling configuration for a group of user equipment. The method may also include receiving, at the user equipment, a point-to-multipoint reconfiguration message using the group-common signaling configuration on the group-common transport channel from a device (e.g., a network node). The point-to-multipoint reconfiguration message may include an updated point-to-multipoint configuration. The method may then include receiving point-to-multipoint data, from the device on the group-common transport channel, based on the updated point-to-multipoint configuration.

Abstract: A method comprises receiving a handover request from a source BS, the handover request comprising a request for a handover of a UE involved in at least two QoS flows using a first MRB with the source BS, wherein the apparatus is using at least a second MRB for other UEs; starting to buffer packets for the UE; receiving a subsequent message comprising, for each of the at least two QoS flows, a CN SN of a first packet not transmitted by the source BS for that QoS flow; identifying a second packet with the highest protocol entity SN according to a protocol entity transmission order of the second MRB among packets which the source BS has delivered to the UE using the first MRB and the apparatus has transmitted to the other UEs using the second MRB; and transmitting a message configuring the UE to use the second MRB.
