Abstract:
1. A method for a device to receive transmissions over a wireless medium, the method comprising: receiving a signal including a physical layer convergence protocol procedure (PLCP) protocol data unit (PPDU) over a wireless communication channel, the PPDU including a preamble having a legacy signaling (L-SIG) modulated with binary phase shift keying (BPSK); and detecting a modulation scheme for modulation of a field immediately following the L-SIG after detection of the L-SIG to determine whether the field immediately following the L-SIG comprises an additional signaling field; and determining that the additional signaling field immediately following the L-SIG is a high throughput signaling field (HT-SIG) when a quaternary binary phase shift keying (QBPSK) modulation scheme is detected.
