17. A device comprising:
radio circuitry configured to facilitate wireless communications of the device over a wireless network; and
a processing element communicatively coupled to the radio circuitry and configured to cause the device to:
receive multiple packets that are duplicate packets over corresponding multiple wireless links from a second device;
generate synchronization information corresponding to a timing between the multiple wireless links, based at least on respective receive timings of the multiple packets; and
transmit the synchronization information to the second device, wherein the synchronization information affects timing of delivery of future multiple packets that are duplicate packets to the multiple wireless links for transmission to the device from the second device.
