Abstract: In accordance with some example embodiments, an apparatus may comprise at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to transmit at least one parameter configuration of a random access channel procedure to a user equipment; receive at least one physical uplink shared channel part of a first random access channel message using at least one transmitter beam configuration; upon detection of at least one preamble part of the first random access channel message, decode the physical uplink shared channel part of the first random access channel message and perform at least one channel quality measurement on at least one demodulation reference signal sequence transmitted on a number of selected transmitter beam configurations.

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.
