Physical layer protocol data unit formats for 60ghz communications

A wireless device, comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the wireless device to:
• receive, via at least a portion of a wireless channel associated with 60 GHz communications, one or more first physical layer protocol data units (PPDUs) having a first format for beam selection;
• select a first beam for communications based at least in part on the one or more first PPDUs;
• and
• receive, via at least the portion of the wireless channel, a second PPDU having a second format for beam refinement, the second PPDU including a preamble portion on one or more sub-bands of a bandwidth of the wireless channel that includes a short training field, a long training field, and at least one signal field that includes one or more 60 GHz parameters related to one or more of a data portion or one or more beam refinement parameters (BRPs) of the second PPDU.

A wireless device, comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the wireless device to:
• encode a data portion of a physical layer protocol data unit (PPDU) in accordance with one or more 60 GHz parameters associated with 60 GHz communications;
• and
• transmit, via at least a portion of a wireless channel associated with 60 GHz communications, the PPDU to at least one other wireless device, the PPDU including a legacy preamble portion on one or more sub-bands of a bandwidth of the wireless channel, a non-legacy preamble portion that spans the bandwidth of the wireless channel, and one or more of a data portion, a packet extension, or a training field portion, the legacy preamble portion including a short training field, a long training field, and at least one signal field that includes one or more 60 GHz parameters related to decoding of the data portion.
