Abstract: At least some aspects of the present disclosure provide for a method of data transmission, performed by a wireless device. In some examples, the method includes receiving a localization tone having a first value. The method further includes inserting the localization tone into a data packet at an application layer of a communication protocol stack, the localization tone preceding data of a payload of the data packet and having a last bit immediately preceding a first bit of the data of the payload. The method further includes generating a modified localization tone estimating an effect of processing on the localization tone, wherein the modified localization tone is generated and configured to have the first value after undergoing processing. The method further includes replacing the localization tone in the data packet with the modified localization tone. The method further includes transmitting the data packet.
