Abstract: The disclosure relates to an apparatus comprising: means for determining (1000) that a second sidelink synchronization reference user equipment extends synchronization coverage of a first sidelink synchronization reference user equipment; means for determining (1002) a first synchronization error between the first sidelink synchronization reference user equipment and the second sidelink synchronization reference user equipment and a second synchronization error between the first sidelink synchronization reference user equipment and the apparatus; and means for determining (1004) whether to operate the apparatus as a sidelink synchronization reference user equipment and extend the synchronization coverage of the first sidelink synchronization reference user equipment based on the first synchronization error and the second synchronization error.

Abstract: Method, apparatuses, and computer program products provide means for monitoring time sources for nodes of a network and providing timing resiliency solutions. An example method includes: establishing time synchronization within a network comprising a plurality of nodes using a time source; receiving an indication regarding at least one of degradation or failure of the time source for at least one node; receiving an indication regarding at least recovery of the time source for the at least one node; and determining, within the network, an action to be taken to upon failure at the at least one node in response to the at least one of the degradation or the failure of the time source for the at least one node, where the action to be taken comprises instructing the at least one node to leverage either hold over functionality or a backup time source.

Abstract: In some example embodiment, there may be provided an apparatus configured to at least receive or generate an indication indicative of two flows including a first flow and a second flow, the two flows carrying data from a first user equipment via a cellular network to a second user equipment. Related system, methods, and articles of manufacture are also disclosed.
