Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a process can include receiving, from a network entity, synchronization information associated with a first set of periodic advertisements (PAs). A first time offset from a reference time can be determined based on the synchronization information, wherein the reference time is associated with synchronization of a plurality of wireless communication devices including the wireless communication device. A second set of PAs can be transmitted at a synchronized time based on the reference time and the first time offset, each PA of the second set of PAs including a constant tone extension (CTE).

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. In one illustrative example, a first network device for wireless communication can receive, from a second network device, a synchronization message comprising synchronization information. The first network device can determine clock information based on the synchronization information. The first network device can generate a clock update command based on the clock information. The first network device can further transmit the clock update command to one or more wireless communication devices associated with the first network device. The first network device can apply the clock information to a clock of the first network device such that the first network device is synchronized with the second network device.

Abstract: Various embodiments include methods for rotating a control node role among devices in a control cluster of a wireless mesh network. Methods may include assuming the control node role by a first device based on a control node assumption timing in a schedule, and transmitting periodic messages to support the wireless mesh network. Methods may further include using the schedule to identify a control node role end timing and a third device in the control cluster that will assume the control node role, transmitting the periodic messages while monitoring for an extended advertisement from the third device after the control node role end timing until the extended advertisement from the third device is received, and assuming a passive node role upon receiving the extended advertisement from the third device or continuing the control node role when no extended advertisement is received from the third device.

Abstract: In an aspect, an asset tracking coordination component estimates a time of a beacon transmission from a wireless energy charging-capable device coupled to an asset within a threshold proximity of a scanning device based on an estimated distance between the asset tracking coordination device and the scanning device and timing information associated with a wireless energy transmission, and schedules a beacon scanning window for the scanning device to scan for the beacon transmission based on the estimated time. In a further aspect, a scanning device may both provide a wireless energy transmission and may also scan for beacon transmission(s) from wireless energy charging-capable device(s) during a beacon scanning window.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a wireless communication device can receive, from a network device, a signal indicating a plurality of slots of time within a subevent interval for transmission of data, wherein the subevent interval is associated with a group of wireless communication devices that includes the wireless communication device. The wireless communication device can transmit one or more data packets within the plurality of slots of time.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a wireless communication device can receive an energizing signal from an energizer and can harvest energy from the energizing signal. The wireless communication device can synchronize, based on one of the energizing signal or a beacon signal, timing for a timing schedule associated with the wireless communication device. The wireless communication device can transmit a signal according to the timing schedule associated with the wireless communication device.

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 handover candidate wherein the handover candidate is a wireless communication device of a plurality of wireless communication devices associated with the network entity. The network entity can transmit to each network device of a plurality of network devices, channel information and scheduling information associated with the handover candidate and can receive, from each network device of the plurality of network devices, energy information associated with a pre-determined packet received by each network device of the plurality of network devices. The network entity can determine a target network device for a handover associated with the handover candidate based on the received energy information.
