Abstract
To receive data in data field of a PHY Protocol Data Unit (PPDU), wherein the data field includes mid-ambles, a number of mid-ambles and a number of data symbols included in the data field is determined. The number of mid-ambles is determined according to information in an HE-SIG-A field of the PPDU, information in an L-SIG field of the PPDU, and one or more predetermined values prescribed by a standard. The number of data symbols may be determined using the number of the mid-ambles, and the data received according to the number of mid-ambles and the number of data symbols.
Claims10
A non-transitory computer-readable media (CRM) including computer programing instructions which, when performed by a processor of a wireless device, cause the wireless device to perform steps 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 a total number of mid-ambles included in a data field of the PPDU;
- determining, using the number of the mid-ambles NMA, a number of data symbols NSYM indicating a total number of data symbols 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.
