The generating of the PDU payload includes inserting a supplemental field and a cyclic redundancy check (CRC) field into the PDU payload. The supplemental field is configured to enable another wireless device to determine an angle of arrival of the AoA packet and the CRC field corresponds to a CRC of at least the supplemental field. The method also includes transmitting the AoA packet with a single antenna of the wireless device.
