5 results about "Physical Layer Convergence Protocol" patented technology

A wireless communication method for determining data includes: receiving, by a first communication device from a second communication device, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) format and decoding, by the first communication device, the PPDU format, where the PPDU format includes a preamble with spreading and a media access control protocol data unit (MPDU).

This disclosure provides methods, components, devices and systems for techniques for tone mapping for 60 MHz distribution bandwidth. Some aspects more specifically relate to techniques for tone mapping for the 60 MHz distribution bandwidth that support distributed transmissions. In some examples, the wireless device may transmit obtain data for transmission in a physical layer convergence protocol (PLCP) protocol data unit (PPDU) over a PPDU bandwidth that exceeds 80 megahertz (MHz) and comprises an 80 MHz distributed transmission subblock, and the 80 MHz distributed transmission subblock may be punctured providing a 60 MHz distribution bandwidth. Tones of the 60 MHz distribution bandwidth may be shifted by tone shift values to align with a boundary of valid tones defined in the punctured 80 MHz distributed transmission subblock of the PPDU bandwidth.

In some examples, the wireless device may obtain data for transmission in a physical layer convergence protocol (PLCP) protocol data unit (PPDU) over an 80 megahertz (MHz) distribution bandwidth. The 80 MHz distribution bandwidth may be punctured providing a 60 MHz distribution bandwidth. A first 20 MHz dRU tone plan, a second 20 MHz dRU tone plan, and a third 20 MHz dRU tone plan may be interleaved over the 60 MHz distribution bandwidth.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to signaling in a trigger frame to support distributed transmissions via distributed resource units (dRUs). In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a wireless station (STA), where the trigger frame carries RU allocation information identifying a distributed resource unit (dRU) allocated for the STA and carries tone mapping information indicating a selected spreading bandwidth design for the wireless channel or subchannel. The AP can support channel puncturing by selecting a particular spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.

In some examples, the wireless device may obtain data for transmission in a physical layer convergence protocol (PLCP) protocol data unit (PPDU) over an 80 megahertz (MHz) distribution bandwidth. The 80 MHz distribution bandwidth may be punctured providing a 60 MHz distribution bandwidth. Cyclic shift delays (CSDs) are respectively applied to a plurality of distribution resource units (dRUs) of the PPDU in accordance with a first CSD index pattern defined for a first 60 MHz or a second 60 MHz of a 80 MHz distribution bandwidth or a second CSD index pattern defined for a first 40 MHz and a second 40 MHz of the 80 MHz distribution bandwidth.
