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: A network access node receives an indication of an interval between expected receptions of echo requests that pass through a tunnel that uses an interface between a network element in a core network of the cellular network to the network access node of the cellular network. The network access node determines a threshold time period based on the interval, detects there has been no echo request for a time period greater than the threshold time period, and determines that a failure has occurred of the tunnel that uses the interface. The network access node triggers set up of a new tunnel using the interface due to the failure of the tunnel. Multiple techniques are disclosed for determining that this failure has occurred and recovering from the failure, including setting up a new MBS session or using a new transport address for a current MBS session.

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: According to an example aspect of the present invention, there is provided a method comprising receiving, by an apparatus, a message while the apparatus is in a radio resource control inactive state, wherein the message comprises a first indication indicating a multicast-broadcast service session to which the apparatus has joined and a second indication indicating to remain in the radio resource control inactive state and in response to receiving the message: in case determining based at least on information received in a radio resource control message that the apparatus belongs to a subset of user equipments, initiating a resumption of a radio resource control connection, and in case not determining that the apparatus belongs to the subset, remaining in the radio resource control inactive state.

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.

Abstract: Example embodiments of the present disclosure relate to configuration and interpretation of control information for a retransmission. A first device receives control information from a second device. In accordance with a determination that the control information indicates a retransmission to be scheduled from the second device. the first device determines an information combination of at least one of the following: at least one field of the control information, a search space in which the control information is received. and a format of the control information. The first device further determines a source traffic type of the retransmission based on the information combination, the source traffic type of the retransmission indicating whether the retransmission is for traffic in a point-to-multipoint initial transmission or in a point-to-point initial transmission.
