Abstract: A wireless communication device for communicating across a wireless communication channel includes a memory storing instructions and one or more processors coupled to the memory to execute the instructions stored in the memory. The instructions are configured to determine a plurality of channel estimation measurements corresponding to a plurality of PPDUs received from an additional wireless communication device; determine a plurality of position measurements using information about the transmission of the plurality of PPDUs, wherein the position measurement is a position of the additional wireless communication device relative to the wireless communication device; select a subset of the plurality of channel estimation measurements based on the plurality of position measurements; and determine a change in a state of the wireless communication channel based on the selected subset of the plurality of channel estimation measurements.

Abstract: In Down Link MU-MIMO, an AP transmits to several STAs concurrently. In the mmWave band, directional transmissions are used so it is necessary for both the AP and the STAs to set their antenna arrays (by setting their antenna weight vectors—AWVs) in the best way to receive the transmissions directed to them by the AP and to avoid interference from transmissions directed to other devices. An exemplary embodiment discloses a beamforming training protocol that is capable of generating a set of antenna weight vectors for MU-MIMO operation that at least improves performance of subsequent communications.

Abstract: This disclosure describes systems, methods, and devices related to non-trigger based (non-TB) sensing. A device may initiate sensing measurements by sending a sensing null data packet announcement (NDPA) frame to an access point (AP) responder. The device may send one or more first null data packet (NDP) packets to the AP responder. The device may identify one or more second NDP packets received from the AP responder.

Abstract: This disclosure describes systems, methods, and devices related to enhanced ranging. A device may initiate a ranging sequence by transmitting an NDPA frame followed by an I2R NDP frame. The device may receive a corresponding R2I NDP frame and an R2I LMR from a responding station. The device may repeat the ranging sequence for two or more iterations to collect multiple data sets. The device may process the R2I NDP frame and the R2I LMR to generate continuous ToA and ToD measurements for each iteration.

Abstract: This disclosure describes systems, methods, and devices related to neighbor awareness networking (NAN) operations in the 6 GHz frequency band. A NAN device may generate a first NAN frame including a first indication of a NAN operation capability, and a second indication of a transmit power of the NAN device. The NAN device may send the first NAN frame and may identify a second NAN frame received from a second NAN device, the second NAN frame including a third indication of the NAN operation capability, and a fourth indication of a transmit power of the second NAN device. The NAN device may determine, based on the transmit power of the NAN device and the transmit power of the second NAN device, an operation parameter for the 6 GHz frequency band. The NAN device may establish, based on the operation parameter, a NAN connection using the 6 GHz frequency band.

Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operation. A device may determine a multi-link communication with a first multi-link device comprising two or more links associated with two or more station devices (STAs) included in the first multi-link device. The device may determine a first medium access control (MAC) address associated with a first link of the two or more links. The device may determine a second MAC address associated with a second link of the two or more links. The device may generate one or more pairwise security keys to be used in the multi-link communication on the two or more links. The device may cause to send a frame to the first multi-link device using at least one combination of the one or more pairwise security keys.

Abstract: Time Sensitive Networks (TSN) are networks that provide time synchronization and timeliness (deterministic latency and reliability/redundancy) guarantees to important or critical data flows. Traditionally, TSN applications have used wired connectivity (e.g., Ethernet TSN) for reliability. However, wiring has several limitations such as high maintenance cost, weight and limited mobility. Moreover, many TSN applications (e.g., Automotive and Industrial control) could benefit from enabling TSN-grade (wired) performance over a wireless network, i.e., a wireless TSN (WTSN) as discussed herein.
