Aspects of the subject disclosure may include, for example, determining anchor pairs from among a group of anchors and a first mobile device that is operating in an anchor mode, where the determining the anchor pairs is based at least in part on anchor locations, and where the anchor locations are known by the server for the group of anchors and for the first mobile device; generating a schedule for communications between the anchor pairs and one or more second mobile devices; and providing the schedule to the anchor pairs, wherein the communications between the anchor pairs and the one or more second mobile devices enables each of the one or more second mobile devices to determine its respective device position. Other embodiments are disclosed.

A remote controlled system for precision tracking of irrigation equipment with GPS and ultra-wideband communication protocol is designed to track irrigation equipment, including a solenoid valve, through use of a global positioning system (GPS), and an Ultra-Wideband (UWB) communication protocol with a remote control device. The system provides a remote control device to track the location of the solenoid valve, or other irrigation equipment. The GPS tracks the approximate location of the solenoid valve, and the UWB communication protocol provides a more precise tracking capability, locating the exact location of solenoid valves, both underground, and above ground. The remote control device and an agricultural clock, are both in signal communication with the GPS and Ultra-Wideband communication protocols. Further, the agricultural clock utilizes a mesh network, i.e., Z-wave to transmit commands that control the timing and amount of water discharged through the solenoid valve across multiple agricultural zones.

A method of operating a base station includes determining a schedule associated with transmission by the base station of a Positioning Reference Signal (PRS) on a plurality of directional beams, the plurality of directional beams having directions corresponding to at least a portion of a plurality of configurable beam directions, the schedule being based on a coordination of the PRS transmission by the base station with PRS transmission on directional beams from at least one other base station; and transmitting the PRS on each of the plurality of directional beams based on the determined schedule.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine its position based on one or more position reference signals (PRSs), which the UE receives via different component carriers (CCs). The UE may maintain an active state with a first CC transmitting a PRS, while activating and deactivating a secondary CC that may transmit PRSs based on a periodic interval. Additionally, the UE may apply similar techniques for inactive BWPs where a PRS spans multiple BWPs. In some implementations, the position of the UE may enhance a UE mobility procedure based on determining a resource to use for the UE mobility procedure that is dependent upon the position of the UE. For example, the UE mobility procedure may include a random access procedure or a handover procedure. Additionally, the resources used for the mobility procedures may be quasi co-located with PRSs.

Aspects presented herein may enable one or more wireless devices to perform a sidelink-based ranging and/or positioning with an assistance of an RIS. In one aspect, a first wireless device receives an information indicating at least a time in which at least one RIS is to be activated. The first wireless device transmits a first set of reference signals to a second wireless device via the at least one RIS. The first wireless receives a second set of reference signals transmitted from the second wireless device via the at least one RIS. The first wireless calculates a first signal RTT based on the first set of reference signals and the second set of reference signals.

Systems and methods of collaborative localization for a vehicle are provided. In particular, one or more vehicles that are able to localize themselves with high accuracy may transmit timestamped localization information (i.e. localization packets) to a nearby vehicles which lack high-accuracy localization sensors. Each localization packet may include the location of the transmitting vehicle with respect to a global reference frame. Upon receiving the localization packets, a vehicle may use radiolocation techniques to estimate its location relative to the transmitting vehicle(s). Based on this estimation and the information in the localization packets, the vehicle may then estimate its location with respect to the global reference frame with a high degree of accuracy.
