    Abstract: This disclosure provides methods, components, devices and systems for partial bandwidth feedback for 480 and 640 MHz transmission in Wi-Fi. Some aspects more specifically relate to the inclusion of a partial bandwidth information field in a null data packet (NDP) announcement frame that indicates for which frequency portions of the 480 or 640 MHz channel bandwidth to generate channel information feedback. In some examples, a receiving device (for example, a station (STA)) may perform channel estimation on an NDP and transmit a beamforming report to the transmitting device (for example, an access point (AP)) based on the NDP. The transmitting device schedules the NDP using an NDP announcement frame, which includes the partial bandwidth information field. The partial bandwidth information field in the NDP announcement frame may include a frequency resolution field and a bitmap with values and lengths based on the channel bandwidth being 480 or 640 MHz.

    Abstract: This disclosure provides methods, devices and systems for interpreting reserved bits and values associated with different releases of a wireless communication protocol. In some implementations, a wireless communication device may determine whether to terminate or continue reception of a physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) if it detects a reserved bit in the physical layer preamble set to an unsupported value (such as a value different than what is defined by a version or release of the wireless communication protocol supported by the wireless communication device). In some other implementations, a wireless communication device may determine whether to terminate or continue reception of a PPDU if it detects a field in the physical layer preamble set to a reserved value (such as defined by a version or release of the wireless communication protocol supported by the wireless communication device).

    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for techniques for reducing feedback information in an extremely high throughput (EHT) wireless local area network (WLAN). A receiving device (beamformee), such as a station (STA), may receive a sounding signal from a transmitting device (beamformer), such as an access point (AP), and transmit channel feedback. The receiving device may transmit the channel feedback as part of a reduced compressed beamforming feedback (CBF) operation that includes determining a first set of channel characteristics. The receiving device may select a subset of the first set of channel characteristics and determine a set of differential characteristics based on the subset. The transmitting device may then transmit the sets of characteristics as reduced CBF to the transmitting device. The transmitting device may determine a channel estimation for beamformed signaling based on the reduced CBF.

    Abstract: This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs for special cases such as, for example, full-bandwidth multi-user multiple-input multiple-output (MU-MIMO), single-user (SU) preamble puncturing, hybrid automatic repeat request (HARQ), and multi-AP coordination. Multi-AP coordination may refer to coordinated beamforming (CoBF), joint transmission (JT), or coordinated orthogonal frequency division multiple access (C-OFDMA). Additionally, or alternatively, some implementations more specifically relate to preamble designs that accommodate signal fields of different cases.

    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.
