Abstract: According to an aspect, there is an apparatus comprising at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to receive, from a serving access node, a downlink radio resource control message comprising reference time information for a clock provided by the serving access node and traceability information for enabling traceability of the clock to a reference time standard. The traceability information comprises at least information on a clock class indicative of a current status of the clock provided by the serving access node.

Abstract: A network node, a core network node and a user equipment are disclosed. The network and the core network node each includes a processor; and a memory storing respective instructions. When executed by the processor, the network node is configured to: determine at least one radio access network timing synchronization status reporting range associated with at least one radio access network timing synchronization status attribute; and transmit, to a second network node, the radio access network timing synchronization status reporting range. The core network node is configured to: determine at least one radio access network timing synchronization status reporting range associated with at least one radio access network timing synchronization status attribute. In addition, the user equipment includes a processor; and a memory storing instructions that, when executed by the processor, cause the user equipment to: determine a clock quality acceptance criteria; and transmit the clock quality acceptance criteria.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for an exposure framework for clock resilience. For example, certain embodiments may provide a way for a network and an application function (AF) to configure a cellular system for timing resiliency. Certain embodiments may utilize a cellular system exposure framework to exchange timing resiliency configuration between the cellular system and AFs.

Abstract: A method, apparatus and computer program product are provided herein to receive, from a source, performance requirements, and cause transmission, to a network, of a request to influence time sensitive communications (TSC) configuration parameters. For example, a method is provided to in response to the request to influence TSC configuration, receive, from the network, network configuration and radio access network (RAN) resource constraints and determine a quality of service (QoS) and the TSC configuration parameters to support a TSC data stream based on the performance requirements received from the source, the network configuration, and the RAN resource constraints. The method is further configured to cause transmission of the determined QoS and the TSC configuration parameters to the network and the source and in an instance the network accepts the determined QoS and the TSC configuration parameters, configure resources for the TSC data stream and continuously support service continuity.

Abstract: Systems, methods, apparatuses, and computer program products for carrying information elements containing timing information to a remote user equipment via a relay UE. One method may include a relay user equipment receiving a system information block associated with reference time information from a network entity, and determining that a remote user equipment needs the reference time information. The method may further include transmitting the system information block to the remote user equipment according to at least one rule associated with the reference time information.

Abstract: Systems, methods, apparatuses, and computer program products for defining service area(s) for time synchronization. A method may include receiving, at a user equipment, time synchronization service area information from a network node in a network. The method may also include selecting a cell for connection based on the time synchronization service area information. The selected cell may maintain a time domain required by the user equipment to remain synchronized with the network.

Abstract: An apparatus, method, and computer program for causing a receiver to perform: receiving, at a lower protocol layer of the receiver from a lower protocol layer of a transmitter, an indication of when a first retransmission mechanism between the transmitter and receiver at the lower protocol layer will terminate; causing retransmission of a data packet according to the first retransmission mechanism; determining, at the lower protocol layer of the receiver using the received indication, that the first retransmission mechanism has been completed in respect of the data packet; and signaling, from the lower protocol layer of the receiver to a radio link control, RLC, protocol layer of the receiver, an indication that the data packet has not been received.
