Abstract: A method includes, when a handheld device is in motion within a service area to be traversed by a robot: obtaining ultra-wideband (UWB) ranging measurements between the handheld device and multiple anchors located in the service area; and obtaining image data and inertial measurement unit (IMU) data. The method also includes determining a trajectory of motion of the handheld device based on the UWB ranging measurements. The method also includes adjusting the trajectory based on image features obtained from the image data and motion estimates obtained from the IMU data. The method also includes identifying the adjusted trajectory as a boundary of the service area.

Abstract: A method includes transmitting, via a transceiver, radar signals for object detection. The method includes determining whether a moving object is detected using received reflections of the radar signals corresponding to a current radar frame. In response to a determination that no moving object is detected using the current radar frame, the method includes determining whether a moving object is detected using received reflections of the radar signals corresponding to multiple radar frames. The method also includes generating a detection result indicating that (i) no moving object is detected using the multiple radar frames or (ii) the moving object is detected using either the current radar frame or the multiple radar frames.

Abstract: A basic service set (BSS) corresponding to an access point (AP) affiliated with an AP multi-link device (MLD) is terminated when the AP is removed. The link ID assigned to the AP is no longer assigned to that AP. A BSS corresponding to an AP affiliated with an AP MLD is not terminated when the link on which the AP is operating is disabled. The affiliated AP maintains the link ID assigned to the AP.

Abstract: Methods and apparatuses for facilitating notification of an impending TDLS transmission in a wireless local area network. The apparatuses include a non-access point (AP) multi-link device (MLD) comprising stations (STAs) and a processor. Each STA comprises a transceiver configured to transceive signals on multi-link operation (MLO) links with APs of an AP MLD and on tunneled direct link setup (TDLS) direct links between the STAs and peer STAs of a second non-AP MLD, and to transmit, to the AP MLD on one of the MLO links, a TDLS transmission notification message. The processor is configured to determine that a TDLS transmission is impending over one of the TDLS direct links from one of the STAs that forms a non-simultaneous transmit/receive (NSTR) link pair with another STA, and to generate the TDLS transmission notification message, which includes an indication that the TDLS transmission is impending.

Abstract: A method includes obtaining range estimates and carrier phase estimates from each of multiple anchors. The method also includes, in response to determining that a trilateration technique is to be performed, (i) obtaining improved range estimates using the carrier phase estimates and (ii) determining a first location estimate of a target device using the trilateration technique and the improved range estimates. The method also includes, in response to determining that a triangulation technique is to be performed, (i) obtaining differential range estimates using the carrier phase estimates and (ii) determining a second location estimate of the target device using the triangulation technique and the differential range estimates. The method also includes combining the first location estimate and the second location estimate to determine an overall location estimate of the target device.
