60 GHZ PHYSICAL LAYER CONVERGENCE PROTOCOL (PLCP) PROTOCOL DATA UNIT (PPDU) FORMATS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17828085 titled '60 GHZ PHYSICAL LAYER CONVERGENCE PROTOCOL (PLCP) PROTOCOL DATA UNIT (PPDU) FORMATS
Simplified Explanation
- This patent application is about methods, devices, and systems for increasing carrier frequencies for wireless communications in wireless local area networks (WLANs). - The focus is on supporting wireless communications on carrier frequencies above 7 GHz. - The wireless communication device maps a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to orthogonal subcarriers based on existing tone plans for frequencies below 7 GHz. - The PPDU is then up-clocked for transmission on frequencies above 7 GHz by increasing the frequency of a clock signal used for conversion between the frequency and time domains. - The PPDU can conform to an existing format designed for sub-7 GHz wireless communications or a new optimized format for frequencies above 7 GHz.
Original Abstract Submitted
This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks (WLANs). Some implementations more specifically relate to packet designs that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a wireless communication device may map a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to orthogonal subcarriers according to existing tone plans associated with carrier frequencies below 7 GHz and may up-clock the PPDU for transmission on carrier frequencies above 7 GHz (such as by increasing the frequency of a clock signal used to convert the PPDU between the frequency domain and the time domain). In some implementations, the PPDU may conform to an existing PPDU format designed for sub-7 GHz wireless communications. In some other implementations, the PPDU may conform to a “green field” PPDU format optimized for wireless communications on carrier frequencies above 7 GHz.
