Abstract: A method comprising transmitting a configuration of a default time period, wherein the default time period is for allowing a terminal device to consider a request for leaving an active network connection to a first network as accepted by the first network if the first network does not send a response within that the default period, to the terminal device, receiving a first message, from the terminal device, indicating a request to leave the active network connection, determining an overriding condition that overrides the default time period for leaving the active network condition and transmitting, to the terminal device, a second message comprising the overriding condition.

Abstract: Systems, methods, apparatuses, and computer program products for improving reliability of mobile-terminated (MT) early data transmission (EDT). The method can include receiving, from a primary transmit receive point (TRP), a message. The method may include transmitting, to the primary TRP, an indication of a capability to receive a multi-TRP transmission of a message 4 of a random access procedure. The indication may be a physical random access channel (PRACH) preamble.

Abstract: Method, apparatuses, and computer program product for overhead reduction are provided. One method may include receiving an allocation of a preconfigured uplink resource and a preconfigured uplink resource radio network temporary identifier associated with the preconfigured uplink resource. The method may also include receiving an assignment of a control channel search space associated with the preconfigured uplink resource. The method may further include monitoring, according to a specified occasion cycle, the control channel search space for a message. In addition, the message may be received according to a specific receive pattern.

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: In this invention, when a serving distributed unit informs target distributed unit via a central unit about a target reference, it is proposed to use, signal index X/indices X1 . . . Xn for PDCCH transmissions or PUSCH receptions or a RACH-less handover:
Send by a distributed unit of the serving cell towards a distributed unit of a target cell one of before, upon, or after transmission of a layer 1 serving cell change command to a user equipment, signaling comprising configuration information associated with the user equipment to perform a random access channel less handover of the user equipment to the target cell, wherein the configuration information informs the target cell about at least one target reference signal index that shall be used for at least one of at least one physical downlink control channel transmission or at least one physical uplink shared channel reception.

Abstract: A method includes receiving, by a first network node that is configured as a master node from a second network node that is configured as a source secondary node for dual connectivity for a user device, control information indicating whether or not the first network node may receive from the second network node an updated measurement configuration based on a list of accepted target Primary Secondary Cells (PSCells) that are accepted by the target secondary node among a list of candidate target PSCells; sending to the user device, a conditional reconfiguration message including the initial measurement configuration that is based on the list of candidate target PSCells if the control information indicated that the first network node will not receive from the second network node an updated measurement configuration; and otherwise, sending a conditional reconfiguration message including the updated measurement configuration that is based on the list of accepted target PSCells.

Abstract: Systems, methods, apparatuses, and computer program products for interworking of measurements gaps and measurement gaps for multiple universal subscriber identity module user equipment are provided. For example, a method can include preparing a gap request to request a gap from a first network for performing an operation with respect to a second network. The gap request can include an indication of criticality of the gap. The method can also include transmitting the gap request from a user equipment to the first network.

Abstract: An apparatus (DU) comprising: means for receiving an identification of a serving network access node; and means for associating a sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node. An apparatus (CU) comprising: means for sending a first message comprising an identification of a serving network access node (sDU) to enable association of a sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node (sDU); and means for receiving, in reply, a second message specifying the association of the sub-set of contention-free-random-access (CFRA) resources with the identified serving network access node (sDU).
