Claim 12:
13. An apparatus, comprising:
a network interface configured to enable network communications;
one or more processors; and
one or more memories storing instructions that when executed configure the one or more processors to perform operations comprising:
encoding a non-high throughput (non-HT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) (non-HT PPDU) to include a first Service Field, a payload field, a first tail field, and a pad field, the pad field or a first value of the first Service Field encoded to indicate preamble puncturing configuration information;
encoding a first parity value in the pad field based on the preamble puncturing configuration information encoded in the first Service field and the preamble puncturing configuration information encoded in the pad field; and
transmitting the non-HT PPDU over a wireless network.
