Abstract: An apparatus and a method for reallocation of global unique temporary identifier (GUTI) in 5G networks are disclosed. The method includes receiving, at a user equipment, a first message from a network, the first message including a first global unique temporary identifier and additional information, at least the first global unique temporary identifier being as-signed to the user equipment; receiving a first data transmission including the first global unique temporary identifier from the network; in response to receiving the first data transmission, deriving, at the user equipment, a second global unique temporary identifier based on the first global unique temporary identifier and the additional information; and receiving a second data transmission including the second global unique temporary identifier from the network.

Abstract: Techniques are disclosed for verification of user equipment (UE) for small data transmission (SDT) when the user equipment is in an inactive state with respect to a communication network. For example, the UE is verified at a selected target gNB upon an SDT resume request initiated by the UE, i.e., a returning UE with respect to the selected target gNB, or otherwise prior to UE data resuming transmission to an anchor gNB from the selected target gNB.

Abstract: According to certain embodiments, a method and apparatus may include performing, by a first network entity, at least one benchmarking procedure of at least one network hop delay per at least one transmit resource towards at least one peer network node identified by at least one internet protocol destination address. The method and apparatus may further include deriving, by the first network entity, a second table, by, for each peer node associated with an internet protocol destination address, determining at least one existing configured mapping of at least one network instance into a transport resource Ti per internet protocol destination address. The method and apparatus may further include updating, by the first network entity, the first table and the second table for each internet protocol destination address and transmitting the updated second table to the second network entity.

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: A method, apparatus, and computer program product provide for generating and providing a signaling indicator to manage quality of service notifications in a network. In the context of a method, the method receives a signaling indicator from a user device. The signaling indicator includes data associated with one or more preferences of the user device. The method further receives a quality of service notification associated with the user device. The method also determines, based on the signaling indicator, whether to provide the quality of service notification to the user device.

Abstract: Systems, methods, apparatuses, and computer program products for data transmission with stateless routing are provided. Certain embodiments may include a radio resource control (RRC)—less or RRC-based mechanism for short data transmission (SDT) in an RRC inactive state, where the mechanism may be performed without storing or establishing a UE context in a distributed unit (DU), for a UE served by a single CU-user plane (UP). Certain embodiments may include a RRC-less mechanism for SDT in an RRC inactive state, where the authentication of the user equipment (UE) may be performed at the UP using UP integrity protection (IP) in a CU-UP. Certain embodiments may include a RRC-based mechanism for SDT in an RRC inactive state, where the authentication of the UE may be performed at the UP using UP IP in a CU-UP and/or at the CP using CP IP in a CU-CP.

Abstract: Embodiments of the present disclosure disclose devices, methods and apparatuses for multicast transmission. A terminal device may receive a mode indication of multicast transmission from a network device. The mode indication may indicate a beam mapping mode which is activated among multiple beam mapping modes, and the beam mapping mode may be associated with a mapping between a transmission beam and a physical downlink control channel (PDCCH) monitoring occasion for the terminal device. The terminal device may further perform a PDCCH monitoring based on the mode indication.
