Abstract: A base station, in communication with a UE using a first serving cell, determines a need to perform a security update for the UE and sends a command including information to perform the security update and indication of a time to execute the security update to change to a new security configuration. In response to the time occurring, a security update is performed to a new security configuration for use for communication with the UE using a second serving cell. The UE receives the information and the indication and performs, without performing a random-access procedure, the security update to the new security configuration to use for communication with the second serving cell.

Abstract: Systems, methods, apparatuses, and computer program products for expediting repetition of an unanswered poll for automatic repeat request (ARQ) feedback are provided. One method includes transmitting a poll to a peer protocol entity to trigger status reporting at the peer protocol entity, starting a timer with a duration that is set based on whether at least one predefined condition is met. The at least one predefined condition depends at least on a value of a sequence number (SN) of a protocol data unit (PDU) in which the poll is transmitted. The method may further include re-transmitting a poll when the timer expires.

Abstract: Systems, methods, apparatuses, and computer program products for protocol data unit (PDU) with service data unit (SDU) segment and indication of SDU-tail length. A method may include transmitting, to a network element, a radio link control data protocol data unit including a non-last segment of a service data unit. The protocol data unit may include an indication of a number of bytes of the service data unit that follow this segment in the service data unit.

Abstract: A method including using master cell group resources for a downlink data transmission to a user equipment, wherein the user equipment is configured with at least one secondary cell group terminated split bearer and a secondary cell group is deactivated; determining, at a centralized central unit user plane, when secondary cell group resources of the deactivated secondary cell group are needed, wherein the determining is based, at least partially, on a data volume threshold for a data radio bearer as configured by a central unit control plane; and based upon the determining that the secondary cell group resources are needed, sending a notification to the central unit control plane to trigger activation of the secondary cell group resources.

Abstract: Embodiments of the present disclosure relate to for inter-CU topology adaptation. A first device establishes a communication interface between the first device and a second device. The first device receives from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed. The first device transmits to the second device a command indicating the second device to activate cells configured by the first device.

Abstract: A method is provided that includes receiving, at a layer of a radio protocol stack, a first uplink unit of data from a higher layer of the radio protocol stack. The first uplink unit of data is in a set of one or more first uplink units of data, and the set is marked with information including an importance value associated with the set that identifies a relative importance of the set compared to other sets within a quality of service flow. The method includes constructing a second uplink unit of data from the first uplink unit of data. And the method includes making a determination to submit the second uplink unit of data to a lower layer of the radio protocol stack, or buffer the second uplink unit of data, based on the importance value associated with the set, and a threshold importance value.
