Abstract: Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

Abstract: A wireless communication device includes a memory, and a processing circuitry coupled to the memory. The processing circuitry is to process a wake-up radio (WUR) frame transmitted by an Access Point (AP), the WUR frame comprising a medium access control (MAC) header and a frame body, the MAC header comprising a Frame Control field, an Address field, and a Type Dependent (TD) Control field, wherein the Frame Control field comprises a Type field; determine, based on a value of the Type field, that the WUR frame is a WUR Discovery frame; determine an identifier (ID) of the AP front the WUR Discovery frame; and in response to a determination that the WUR frame is a WUR Discovery frame, cause a Primary Connectivity Radio (PCR) corresponding to the wireless communication device to communicate with the AP based on the WUR Discovery frame.

Abstract: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a portion of a physical layer (PHY) protocol data unit (PPDU), the first portion of the PPDU including a physical universal signal field (U-SIG), the U-SIG comprising a version independent portion and a version dependent portion, the version independent portion including a version identifier field, the version identifier field indicating a standard version of the PPDU. The processing circuitry is further configured to refrain from decoding the version dependent portion when the standard version indicates a standard version of a later generation than a standard version of the AP or STA, and otherwise decode the version dependent portion in accordance with the standard version.

Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station, duty cycle timing for transmission to a second station via a primary connectivity radio. A wake-up radio (WUR) receiver (WURx) is enabled to receive a transmission based upon the duty cycle timing of the WURx when the primary connectivity radio is in a doze state from a perspective of the second station. A wake-up packet, received from the second station, is decoded and received by the WURx. The WURx receives a WURx transmission when in an WURx awake state. The primary connectivity radio is enabled based upon decoding the wake-up packet.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The STA may determine a portion of a channel occupied by an incumbent device. The STA may refrain from communication in a first subset of resource units (RUs) that overlap the portion of the channel occupied by the incumbent device. The STA may determine a combined RU that comprises two or more RUs of a second subset of RUs that do not overlap the portion of the channel occupied by the incumbent device. The STA may encode a physical layer convergence procedure protocol data unit (PPDU) for transmission in the combined RU. The PPDU may be encoded in accordance with joint coding across the RUs of the combined RU.

Abstract: Methods, computer readable media, and apparatus for determining a receive (Rx) number of spatial streams (NSS) for different bandwidths (BWs) and modulation and control schemes (MCSs) are disclosed. An apparatus is disclosed comprising processing circuitry configured to decode a supported HE-MCS and a NSS set field, the supported HE-MSC and NSS set field received from an high-efficiency (HE) station. The processing circuitry may be further configured to determine a first maximum value of N receive (Rx) SS for a MCS and a bandwidth (BW), where the first maximum value of N Rx SS is equal to a largest number of Rx SS that supports the MCS for the BW as indicated by the supported HE-MCS and NSS set field; and, determine additional maximum values based on an operating mode (OM) notification frame, and a value of an OM control (OMC) field. Signaling for BW in 6 GHz is disclosed.

Abstract: Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In sonic embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.
