Abstract: A method detecting at least one of a mobility failure and a respective successful handover; determining a type of the mobility failure, wherein the type of the mobility failure is determined in response to the detected mobility failure; generating mobility failure information indicative of one or more parameters associated with the type of mobility failure, wherein the mobility failure information is generated, at least in part, based on the determined type of the mobility failure; and providing the mobility failure information and/or successful handover information including, at least in part, one or more parameters associated with the respective successful handover, wherein mobility failure information and/or successful handover information enable a network to determine whether a root cause associated with at least one of a respective mobility failure information and a respective successful handover information is a misconfiguration of one or more parameters controlling L3 handover procedures or L1/2 inter-cell mobility.

Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include attaching, by a user equipment, to a visited public land mobile network as inbound roamer. The user equipment then receives a service announcement comprising at least one of a multicast service session allowed to be accessed by inbound roamers indication or multicast service class. The user equipment determines whether the user equipment is allowed to access a multicast session or multicast service class in the visited public land mobile network. The user equipment transmits, in response to determining that the user equipment is allowed to access, a request to join a multicast session comprising an identifier of the multicast session and/or a multicast service class. The user equipment receives an indication of an acceptance or rejection of the request to join the multicast session.

Abstract: Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for a transmission indication for a multicast service. In a method, a first apparatus receives a wakeup signal indicating that a next transmission for a multicast service is a new initial transmission or a retransmission. In response to receiving the wakeup signal, the first apparatus performs an action.

Abstract: This specification describes a terminal device configured to transmit a message relating to a change or addition of a primary cell of a secondary cell group, the message including (i) information indicative of a first user plane interruption time experienced by the terminal device and associated with the change or addition of the primary cell, and (ii) an indication of a first data radio bearer type to which the first user plane interruption time relates. It also describes a radio access node which receives the message.

Abstract: Embodiments of the present disclosure relate to reliable SPS configuration for MBS. In the solution, a first device starts a first timer upon receiving, from a second device, configuration of a semi-persistent scheduling (SPS) for a multicast and broadcast service (MBS). Then if the first timer expires and there is no information received to activate corresponding SPS scheduled transmissions, the first device transmits to the second device a message indicating that the first device failed to receive the information. This solution allows reliable SPS configuration for MBS.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for search space configuration for multicast traffic. According to embodiments of the present disclosure, a first device determines, from a group of search space sets configured to the first device, at least one search space set for monitoring multicast traffic from a second device, based on at least one of a priority of the multicast traffic and respective types of the search space sets. The first device monitors the multicast traffic from the second device in the at least one search space set. The solution enables multicast traffic to be monitored in a common search space set, a user-specific search space set or a multicast search space set in different scenarios.

Abstract: There is herein disclosed a method for receiving, from a radio access network node, a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of the UE for a plurality of target cells. The method further comprises receiving, from the radio access network node, an indication that the UE is allowed to select and connect to a preferred target cell from the plurality of target cells. The method further comprises selecting the preferred target cell from the plurality of target cells based on network slice area of service availability information for each target cell configured at the UE and the radio condition and transmitting, a request to connect to the preferred target cell.

Abstract: A H-SMF receives, from a V-SMF in a VPLMN, a join request originating from a UE roaming in the VPLMN to join a multicast multicast and broadcast services (MBS) session, and determines whether the UE is authorized to join the multicast MBS session based upon a local configuration in a home public land mobile network, information received from an application function during establishment of the multicast MBS session, and/or user subscription data received from a user data manager. The H-SMF at least one of: transmits to the V-SMF, if the UE is authorized, an acceptance response configured to establish at least one unicast QoS flow corresponding to multicast QoS flow information received from a H-MB-SMF, or, if the UE is not authorized, a rejection response comprising error cause information indicating that the UE is not authorized to join while roaming.

Abstract: Disclosed are methods and apparatus for multiplexing NACK-only HARQ feedback. A terminal device in a communication network may comprise at least one processor and at least one memory having computer program code stored thereon. The at least one memory and the computer program code may be configured, with the at least one processor, cause the terminal device to perform: receiving, from a network device, one or more uplink control channel configurations for transmitting HARQ feedback for multicast transmission of one or more services; receiving, from the network device, the multicast transmissions of the one or more services; converting HARQ feedback bits of the HARQ feedback for the multicast transmissions of the one or more services; multiplexing the converted HARQ feedback bits into a multiplexed HARQ feedback; selecting a physical uplink control channel (PUCCH) resource for transmission of the multiplexed HARQ feedback; and transmitting the multiplexed HARQ feedback using the selected PUCCH resource.
