Abstract: Disclosed are methods, devices, systems, apparatus, servers, media, and other implementations, including a method, performed at a first wireless device, for secure range determination that includes transmitting a first signed message at a first time instance, with the first signed message, including a first payload, configured to be received by a second wireless device at a second time instance, and receiving at a fourth time instance a verifiable acknowledgement message transmitted from the second wireless device at a third time instance in response to the first signed message. The method further includes verifying that the verifiable acknowledgement message originated from the second wireless device, and, responsive to a verification that the verifiable acknowledgement message originated from the second wireless device, transmitting a second signed message including a second payload with at least timing information for the first time instance and the fourth time instance.

Abstract: Systems and techniques are provided for wireless communications. For example, a process can include receiving, from a first network entity a request to identify one or more additional network entities available for communication with a wireless communication device. A process can include transmitting, to a second network entity included in the one or more additional network entities, timing information indicative of a difference between first synchronization information associated with the first network entity and second synchronization information associated with the second network entity. A process can include receiving, from the second network entity, subframe allocation information corresponding to periodic advertisements (PAs) between the second network entity and the wireless communication device. A process can include receiving, from the second network entity, a PA based on the subframe allocation information.

Abstract: Systems and techniques are provided for wireless communications. For example, a process can include transmitting, to a network entity, first channel map information of a wireless communication device, wherein the first channel map information includes one or more channels associated with the wireless communication device. A process can include receiving, from the network entity, an identifier of a particular subframe of a plurality of subframes and a subframe channel map of the particular subframe, wherein the wireless communication device is allocated to the particular subframe based on a comparison of the one or more channels included in the first channel map information and one or more channels included in the subframe channel map of the particular subframe. A process can include transmitting, to the network entity, a periodic advertisement (PA) response using a channel included in the subframe channel map of the particular subframe.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a process can include determining, by a network entity, a transmit power value for communicating with a wireless communication device. The network entity can select a subframe of a plurality of subframes, wherein the subframe is selected based on the transmit power value and a respective subframe transmit power value associated with the subframe, and wherein the respective subframe transmit power value is greater than or equal to the transmit power value. The process can further include allocating the wireless communication device to the subframe and transmitting a periodic advertisement (PA) to a plurality of wireless communication devices using the subframe and the respective subframe transmit power value, wherein the plurality of wireless communication devices includes the wireless communication device.

Abstract: Various embodiments may provide systems and methods for determining a distance to a short in a two-conductor wire. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a phase difference between a phase of an injected tone and a phase of a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on both a phase difference and an amplitude difference between an injected tone and a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a measured peak voltage of a combined pulse.
