PHYSICAL LAYER (PHY) PACKET DESIGN FOR POWER SPECTRAL DENSITY (PSD) LIMITS

Abstract:

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for physical layer (PHY) packet design for power spectral density (PSD) limits. In some implementations, a wireless communication device generates a plurality of PHY convergence protocol (PLCP) protocol data unit (PPDU) duplicates configured for transmission over a selected bandwidth, and transmits each PPDU duplicate of the plurality of PPDU duplicates on a corresponding frequency subband of a plurality of different frequency subbands. In some other implementations, the wireless communication device generates a PPDU for transmission over a set of duplicated resource units (RUs) allocated to the wireless communication device, and transmits the PPDU over the allocated set of duplicated RUs.
