Abstract: Disclosed are techniques for wireless communication. In an aspect, an asset tracking device receives a set of group scheduling parameters for a plurality of asset tracking devices assigned to a plurality of assets in a shipment, wherein the set of group scheduling parameters comprises a global wakeup start time and a time interval between consecutive wakeup times, wherein the shipment comprises a plurality of stops, including a starting stop, one or more intermediate stops, and an ending stop, and wherein each of the plurality of asset tracking devices has a target stop of the plurality of stops, and, at each wakeup time of at least a set of wakeup times of the consecutive wakeup times: obtains one or more positioning measurements, transmits the one or more positioning measurements, synchronizes a local clock of the asset tracking device to a global time protocol, and transitions to a sleep mode.
