Abstract: This application provides a communication method and apparatus. The method may include: A terminal device obtains first indication information, where the first indication information indicates at least one multicast key transmission procedure, each multicast key transmission procedure is a communication procedure that is supported by a network side and that is used to transmit a multicast key to the terminal device, and the multicast key is a security transmission key of a multicast session between the terminal device and a first content delivery network element. The terminal device obtains service data from a core network based on a support case of the terminal device for the at least one multicast key transmission procedure.

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: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Specifically, the disclosure related to systems and methods for configuring and controlling state transitions of UEs for NR MBS multicast service reception in an RRC inactive state. The methods include controlling state transitions based on one or more configured threshold parameters. The methods include providing an access category setting, and an access barring operation for performing an RRC resume procedure for receiving multicast in the RRC inactive state. Further, the methods include performing an RRC resume procedure based on an SIB1/SIB24 scheduling status.

Abstract: A method for detecting downlink control information (DCI) is performed by a terminal. The method includes: detecting and receiving at least one DCI according to a priority order of multiple DCIs within a time unit; wherein the multiple DCIs comprise at least one DCI for simultaneously scheduling multicast broadcast service (MBS) of multiple terminals; and in response to determining that a number of DCIs detected and received within the time unit reaches a maximum DCI number that the terminal supports to detect within the time unit, stopping detecting DCI within the time unit.

Abstract: A method and apparatus for paging information on a Multicast/Broadcast Service (MBS) bandwidth part (BWP) in a wireless communication system is provided. The method comprises receiving a Multicast/Broadcast Services (MBS) service on an MBS Bandwidth Part (BWP), wherein the MBS BWP is not overlapped with an initial BWP; receiving paging information on the MBS BWP, wherein the paging information includes information related to a paging message on the initial BWP; switching from the MBS BWP to an initial BWP, based on the paging information; and receiving the paging message on the initial BWP.

Abstract: A method for delivering data to User Equipments (UEs) is implemented in a node of a Radio Access Network (RAN), and includes receiving, from a network node, a packet including data that is to be delivered from a Core Network (CN) to one or more User Equipments (UEs); transmitting the packet to at least some of the one or more UEs via a broadcast transmission when the packet is received via a common downlink tunnel or via a first DL tunnel of a plurality of DL tunnels; and transmitting the packet to a particular UE of the one or more UEs via a unicast transmission when the packet is not received via the common downlink tunnel or is received via a second DL tunnel of the plurality of DL tunnels.

Abstract: To manage multicast and unicast data transmissions. a base station receives. from a core network (CN), a multicast and/or broadcast services (MBS) downlink data packet via a downlink tunnel (602). The base station determines whether to transmit the MBS downlink data packet to a plurality of UEs via unicast or multicast. Then the base station transmits the MBS downlink data packet to a plurality of first UEs via a multicast data transmission (606), and/or transmits the MBS downlink data packet to a plurality of second UEs via a plurality of unicast data transmissions (608).

Abstract: Embodiments relate to e.g. a method performed by radio network node (12) for paging a UE (10) in a wireless communication network. The UE (10) transmits a paging signal on a carrier to the UE (10), wherein the carrier is associated with a second paging signal for a second type of UEs. A first number of carriers are configured for a first paging signal of a first type of UEs and a second number of carriers are configured for the second paging signal of the second type of UEs, wherein the first paging signal comprises a first wake-up signal, WUS, and wherein the second paging signal comprises a group wake up signal, WUS, for a group of UEs of the second type of UEs.
