Abstract: Systems, methods, apparatuses, and computer program products for inter-gNB small data transmission (SDT) routing at a radio access network (RAN). A method may include transmitting an initial request message from a first element in a first network node, to a second element in the first network node to obtain context information. The method may also include receiving, at the first element, a context setup request message based on the context information containing a transport layer information of a third element of a second network node and context information of a user equipment in the second network node. The method may further include processing a data packet according to the received context information. In addition, the method may include forwarding the data packet to the third element of the second network node according to the received transport layer information.

Abstract: Systems, methods, apparatuses, and computer program products for neighbor cell measurement based timing advance validation. A method may include receiving a network configuration comprising a timing advance command from a network element. The method may also include acquiring at least measurement data of a serving cell relative to a first set of neighbor cells at a first time instance, and measurement data of the serving cell relative to a second set of neighbor cells at a second time instance according to the network configuration. The method may further include performing a timing advance validity check using at least the acquired measurement data from the first time instance and the second time instance. Further, the method may include performing data transmission based on a result of the timing advance validity check.

Abstract: Improved techniques of managing measurement gaps for MPUEs include identifying an idle time for the UE in a coordinated and network-controlled manner during which the UE is able to perform SSB/CSI-RS based measurements for a serving cell using non-serving panels. Such idle time is defined as an omitted operation time (i.e., an idle time of a certain pre-defined length) in which the network has to apply the scheduling restrictions in the SSBs' symbols to the UE. Note that currently as per the RAN4 requirements, the network must apply scheduling restrictions in all SSB symbols for all UEs in FR2 at any time (i.e., worst case scenario).

Abstract: A method, apparatus, and a computer-readable storage medium are provided for providing optimized multi-connectivity and/or data duplication. In one example implementation, the method may include receiving, by a user equipment (UE), packet transmission pattern information from a first network node of one or more network nodes and transmitting, by the user equipment (UE), the consecutive packets using the different radio links indicated in the packet transmission pattern information. In an additional example implementation, the method may include determining, by a network node of a set of network nodes, packet transmission pattern information for a user equipment (UE). The example method may further include transmitting, by the network node, the packet transmission pattern information to the user equipment (UE). In a further additional example implementation, the method may include determining, by a network node of one or more network nodes, packet transmission pattern information of a user equipment (UE) and transmitting, by the network node, the packet transmission pattern information to another network entity. The example method may further include transmitting, by the network node, one or more packets received from the another network entity.

Abstract: Embodiment of the invention include a process of receiving an indication from a first wireless network to configure a user equipment to enter a first operating mode, wherein the first operating mode comprises performing measurements according to a first time pattern for at least one second wireless network signal to detect at least one second wireless network; determining whether the user equipment is stationary; and identifying, at the user equipment, a first condition from at least the measurements performed according to the first time pattern which triggers the user equipment to autonomously enter a second operating mode while the user equipment is determined to be stationary.

Abstract: A method is provided including configuring, by a network node, a set of resources to be used by at least one user equipment for transmitting a first type of uplink data; receiving from the at least one user equipment information that indicates that at least one resource in the set of resources comprises a second type of uplink data different than the first type of uplink data; and decoding data received on the at least one resource based on the information.

Abstract: Various communication systems may benefit from the appropriate aggregation of multiple radio access technologies. For example, certain communication systems may benefit from optimized signaling for wireless local area network and third generation partnership projection aggregation. A method can include determining, by a network element, which parameters according to a first standard are also applicable according to a second standard for aggregation and/or interworking. The method can also include indicating the determined parameters to a user equipment.

Abstract: Example embodiments relate to devices, methods, apparatuses and computer readable mediums for paging information and paging-related actions. A terminal device may receive via a first cell first paging information related to a second cell or another carrier of the first cell, and to perform a paging-related action via the second cell or said another carrier based on the first paging information. Synchronization signals are not transmitted in the second cell or said another carrier. The paging-related action may include monitoring for second paging information in the second cell or said another carrier if the first paging information includes a paging early indication, a wake-up signal, or a scheduling message for scheduling a paging message, or performing at least one action for transferring information via the second cell or said another carrier if the first paging information includes a paging message or a wake-up signal.

Abstract: A terminal device, initially, maintains, in at least one memory, a configuration for a Radio Resource Control, RRC, inactive state. The configuration includes information on a radio access network notification area, RNA. The terminal device, then, acquires information on an expected latency of incoming RRC messages within the RNA. In response to triggering a RRC connection resume procedure, the terminal device performs the following: First, the terminal device transmits a RRC connection resume request to a target access node and starts a timer defined based on the expected latency. In response to the timer expiring, the terminal device initiates monitoring of incoming RRC messages. In response to receiving a RRC connection resume message, the terminal device initiates the RRC connected state.
