Abstract: A method, apparatus, and a computer-readable storage medium are provided for NG based context release and data forwarding for multi-hop mobility. In an example implementation, the method may include a core network entity receiving a first message from a first network node, the first message including at least one of a user equipment context release request and a data forwarding request and detecting the at least one of the user equipment context release request and the data forwarding request from the first message. The method may further include sending a second message including at least one of a user equipment context release command and data forwarding information to a second network node based at least on the detected at least one of the user equipment context release request and the data forwarding request.

Abstract: A method includes receiving, by a user equipment (UE), at least a first UE identity assigned to the user equipment for a wireless network, the first UE identity associated with a first paging timing; and receiving, by the user equipment, a second UE identity that has been assigned to the user equipment at least for paging purposes that adjusts a paging timing from a first paging timing associated with the first UE identity to a second paging timing associated with the second UE identity, wherein the second paging timing is different from the first paging timing.

Abstract: Certain embodiments may relate to communication systems, and, for example, some embodiments may relate to multi-QoS level uplink grants. According to a first embodiment, a method may include transmitting, by a first network entity, one or more grants of one or more uplink resources to a second network entity. The one or more grants of one or more uplink resources includes one or more physical resource allocation parameters containing one or more logical channel groups. The method may further include receiving, by the first network entity, data from the second network entity allocated according to the one or more logical channel groups.

Abstract: A method includes: detecting a need for a retransmission of a data transmission on one or more bandwidth parts (BWP) between a user apparatus and a radio access network; and in response to detecting the need for the retransmission, resetting a timer, wherein an expiration of the timer causes automatic switching from using the one or more BWPs for the data transmission to using a default BWP for the data transmission.

Abstract: The present disclosure relates to a simple and power-efficient procedure that allows using wake-up signaling in inter-cell mobility scenarios. The procedure is based on configuring a Wake-Up Signal (WUS) Beacon Occasion (WBO) for each Tracking Area (TA) of a user device. A WUS beacon corresponding to each cell in the TA is transmitted once at a cell-specific time offset within the WBO. The WBO is configured together with a mapping table that maps each of the cell-specific time offsets to cell-specific information. The cell-specific information may comprise a cell ID and/or an indicator of a cell-specific frequency and/or cell-specific frequency range to be used for synchronization signal reception (e.g., Global Synchronization Channel Number (GSCN)). Each TA comprises intra-frequency cells only. By using the WBO, the user device may reduce its power consumption by avoiding switching from its sleep state to its active state when doing cell reselections in the TA.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of UL data duplication avoidance. The method includes obtaining, from an application layer of a terminal device, at least one UL data to be transmitted to a network device, the at least one UL data including one or more application retransmission data and keeping the one or more application retransmission data in a buffer of the terminal device for respective time intervals. The method further includes in accordance with a determination that an indication, that respective acknowledges are received for at least a portion of application retransmission data in the one or more application retransmission data, is received from the application layer, removing the portion of application retransmission data from the buffer. In this way, redundant retransmission of UL application data may be avoided.

Abstract: In order to perform small data transmission during an RRC_INACTIVE mode, a UE may need to determine whether the stored timing advance (TA) is valid. A TA may be valid if its usage would result in an uplink transmission arriving at a TRP of a base station during a time period during which the base station expects to receive uplink transmission. A UE may determine that a TA is valid based on a received fraction of the length of a cyclic prefix and observed SSB time shift.

Abstract: A method, apparatus and computer program product are provided in accordance with example embodiments in order to provide for the efficient, dynamic distribution of traffic in a hybrid network environment based at least in part on reliability probabilities associated with individual subflows within the network. In some example implementations, a traffic distribution entity provides for control over the determination of combined reliability probabilities of multiple potential traffic distribution modes and the selection of a traffic distribution mode that is capable of meeting performance targets, such as those associated with mission-critical operations of cyber-physical systems.
