Abstract:
Systems and methods of expanding indication capabilities of existent PPDU preamble fields. An existing field “Doppler mode” in a preamble is redefined into a dual-use field for indicating channel variation for a short packet as well as for indicating presence of mid-amble(s) in a long packet. Particularly, for a long packet (longer than a predefined data transmission time or a longer than a predefined number of data symbols), the two possible values of the one-bit “Doppler mode” field indicate whether there is any mid-amble carrying training symbols in the payload. On the other hand, for a short packet, the two possible values in the same field indicate whether the channel for transmitting the instant packet is currently time-variant as determined by the transmitting device.

Claim (Index 15):
A device comprising:\n a memory; a processor coupled to said memory; and a transceiver comprising a signal processor and configured to:\n receive a first packet transmitted from a wireless channel; \n based on a determination that a data length of said first packet is shorter than a first limit, use a value of a first field in a preamble of said first packet as an indication of whether said wireless channel is time-variant; and \n based on a determination that said data length of said first packet is greater than said first limit, use a value of said first field as an indication of whether a Doppler mode mid-amble is present in a payload of said first packet.
