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 17):
The device of  claim 16 , wherein said transceiver is further configured to, based on a detection that said first field has said first value and based on said determination that said data length is greater than said first limit, automatically determine that said first packet comprises a Doppler mode mid-amble in said payload and resolving said Doppler mode mid-amble in a channel estimation process.
