Abstract:
This disclosure provides methods, components, devices and systems for service period based coordinated spatial reuse. Some aspects relate to long term signaling to reduce the amount of signaling while achieving the gain associated with coordinated spatial reuse as compared to distributed spatial reuse. A first wireless device associated with a first basic service set (BSS) may transmit a beacon indicating a set of service periods designated for spatial reuse and an interference threshold. A second wireless device associated with a second BSS may receive the beacon and may communicate with one or more other wireless devices associated with the second BSS during the set of service periods designated for spatial reuse in accordance with the indicated interference threshold. Accordingly, the wireless devices in the second BSS may communicate at a power level that causes an acceptable level of interference at the first BSS.
Abstract:
This disclosure provides methods, devices and systems for wireless communication, and particularly, for generating or receiving a multi-generation physical layer protocol data unit (PPDU). The multi-generation PPDU may concurrently include a first generation-specific preamble based on a first generation of a wireless communication specification (such as that defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards) and a second generation-specific preamble based on a second generation of the wireless communication specification in a same transmission. The generation-specific preambles may be generated based on bandwidth portions of a wireless channel that each generation-specific preamble will occupy in the multi-generation PPDU. One or more of the generation-specific preambles may be modified based on an aggregate bandwidth of the multi-generation PPDU. This disclosure includes several options for modifying one or more generation-specific preambles or data fields to accommodate their use in a multi-generation PPDU.

This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for generating or receiving a wireless packet that includes a first preamble based on a first generation of a wireless communication protocol and a second preamble based on a second generation of the wireless communication protocol. The wireless packet may include the first preamble in a first subchannel of a wireless channel and the second preamble in a second subchannel of the wireless channel. Thus, the wireless packet may concurrently include communication to or from different types of wireless stations that support the different generations of a wireless communication protocol.

Abstract:
This disclosure provides methods, components, devices, and systems that support sounding techniques for ultra-high reliability (UHR) communications. In some implementations, a first communication device may receive a null data packet announcement (NDPA) frame associated with a UHR NDPA variant type. The NDPA frame may include sounding information for communication devices that support UHR communications. The first communication device may receive a null data packet (NDP) in accordance with the sounding information, and may perform UHR communications based on measurements of the NDP. In some other implementations, the first communication device may receive a trigger frame that indicates the NDPA, a sounding mode for transmission of the NDP, and parameters for transmission of a compressed beamforming frame (CBF) associated with the NDP. The first communication device may transmit or receive the NDP in accordance with the sounding mode, and may receive or transmit the CBF using the parameters.
Abstract:
Duplicated physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmission is described for a wireless device with reduced peak-to-average power ratios (PAPR). One example includes obtaining a first sub-PPDU from ta PPDU that includes a data field with data content. A second sub-PPDU may also be obtained by duplicating the PPDU including the data content of the PPDU. At least one of a phase rotation, a phase offset, or a phase ramp is applied to at least a portion of a second set of sub-carrier of a wideband channel. The first sub-PPDU is transmitted on a first set of sub-carriers of the wideband channel and the second sub-PPDU is transmitted on the second set of sub-carriers of the wideband channel.
