1. A method performed by a wireless device, the method comprising:
receiving a first portion of a PHY Protocol Data Unit (PPDU), the first portion including a Legacy Signal (L-SIG) field;
decoding the L-SIG field;
determining a format of the PPDU using the first portion; and
in response to determining that the format of the PPDU is a High Efficiency (HE) format:
receiving and decoding an HE Signal A (HE-SIG-A) field,
determining, using a Doppler field of the HE-SIG-A field, whether the PPDU includes mid-ambles, and
in response to determining that the PPDU includes mid-ambles:
determining, according to the format of the PPDU and using first information determined using the HE-SIG-A field and second information determined using the L-SIG field, a number of mid-ambles NMA indicating the number of mid-ambles included in a data field of the PPDU,
wherein the number of mid-ambles NMA is determined without using a number of data symbols NSYM included in the data field of the PPDU;
determining, using the number of the mid-ambles NMA, the number of data symbols NSYM included in the data field of the PPDU; and
receiving, using the number of mid-ambles NMA and the number of data symbols NSYM, the data field of the PPDU.
