17. A device comprising:
radio circuitry configured to facilitate wireless communications of the device over a wireless network; and
a processor communicatively coupled to the radio circuitry and configured to interoperate with the radio circuitry to:
transmit multiple packets that are duplicate packets to a receiver over at least two wireless links;
receive synchronization information corresponding to a timing difference between the two wireless links, wherein the synchronization information is based at least on respective receive timings of the multiple packets over the two wireless links at the receiver; and
control delivery timing of future respective multiple packets that are duplicate packets for transmission to the receiver over the two wireless links, based on the synchronization information.
