PHYSICAL LAYER PREAMBLE DESIGN

Abstract:

This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. Among other examples, the preamble designs of the present implementations may allow for more reliable packet detection, more accurate channel estimation, and more robust decoding of signal field (SIG) symbols. Additionally, or alternatively, the preamble designs of the present disclosure may be implemented with different lengths, modulation schemes, or transmit power compared to preamble designs that conform to existing versions of the IEEE 802.11 standard.
