Abstract: 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 and numerologies that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a wireless communication device may up-clock a physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) for transmission on carrier frequencies above 7 GHz, where the PPDU conforms to an existing PPDU format associated with carrier frequencies below 7 GHz. As used herein, the term “up-clocking” refers to increasing the frequency of a clock signal used to convert the PPDU between the frequency domain and the time domain. In some aspects, the up-clocking may result in a subcarrier spacing (SCS) greater than or equal to 1.2 MHz, where the SCS represents a spacing between the subcarriers on which a PHY preamble of the PPDU is modulated.

Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.
