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.

Abstract: Apparatuses, method, and computer-program for a mobile telecommunication network comprising multiple public land mobile networks sharing a radio access network node are provided. An apparatus of one of the multiple public land mobile networks may include at least one processor; and at least one memory comprising: instructions which, when executed by the at least one processor cause the apparatus at least to: receive, from an application function of a content provider, a request for allocation of a temporary mobile group identity for a shared multicast/broadcast session comprising an index value to be used to select a temporary mobile group identity for the shared multicast/broadcast service from the list of temporary mobile group identities for shared services; select, based on the index value, a temporary mobile group identity for the shared multicast/broadcast service from a list or range of temporary mobile group identities for shared services; and send, to the application function, the selected temporary mobile group identity for the shared multicast/broadcast service.

Abstract: In an MN in wireless communication with a UE and in communication with SN(s), after receiving an indication from the UE that an SCG failure has occurred, determining by the MN which node of at least the MN or a last serving SN or another SN is responsible for the SCG failure. Based on the outcome, performing by the MN an analysis for mobility robustness for the SCG failure where the MN was responsible for the SCG failure. In an SN, of an SCG, determining whether or not the SN is responsible for an SCG failure. In response to receiving from the MN a message corresponding to the SCG failure, indicating to the master node by the secondary node whether or not the secondary node is responsible for the secondary cell group failure.

Abstract: Example embodiments of the present disclosure relate to semi-static HARQ-ACK codebook construction for frequency-multiplexed DL data transmission. A first device includes at least one processor; and at least one memory including computer program codes; wherein the at least one memory and the computer program codes are configured to, with the at least one processor, cause the first device to: receive downlink configuration information from a second device, receive at least two frequency-multiplexed downlink transmissions at one downlink data transmission occasion, and set, based on the downlink configuration information and an error state of the frequency-multiplexed downlink data transmissions, an acknowledgment indication in a semi-static HARQ-ACK codebook to be transmitted to the second device for the downlink data transmission occasion.

Abstract: According to an example embodiment, a network device is configured to:
generate an indicator based on at least one of an activation status of a multicast session or a data inactivity status; and transmit the indicator to a client device, wherein the indicator indicates to the client device whether the client device should wait for a paging message for the multicast session and stop monitoring data of the multicast session while the client device is in an inactive state.

Abstract: Methods, devices, apparatuses, and computer readable medium for enhancements on service continuity. The method includes receiving, at a source network node and from a user equipment, UE, being served by the source network node for a service associated with a network slice, a message indicative of a target network node for a handover of the UE from the source network node to the target network node; transmitting a handover request to the target network node, the handover request indicating urgency of the handover for the UE, and the target network node being overloaded for the network slice; and receiving a handover request acknowledgement message from the target network node, the handover request acknowledgement message indicating if multi-carrier radio resource sharing is applicable for supporting the service.

Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include receiving, by a user equipment attached to a public land mobile network as an inbound roamer, a service announcement for a broadcast session or service class indicating whether inbound roamers are allowed to access the broadcast service or service class; determining, based on the service announcement, whether the user equipment is allowed to access a broadcast session or service class in the public land mobile network; and in response to determining that the user equipment is allowed to access a broadcast session or service class in the public land mobile network, transmitting, by the user equipment, a multicast/broadcast service interest indication associated with the broadcast session or service class upon completion of a radio resource request.
