Disclosed are techniques for wireless communication. In an aspect, a position estimation entity, obtains first timing information that is associated with a first time-of-arrival (TOA) measurement of a first reference signal for positioning (RS-P) as communicated between a target user equipment (UE) and a base station with a first time basis, obtains second timing information that is associated with a second TOA measurement of a second RS-P as communicated between the target UE and a reference UE associated with a known location and having a second time basis that is different than the first time basis, determines a bias between the first time basis and the second time basis, and determines a position estimate of the target UE via a time differential of arrival (TDOA) positioning technique based at least in part upon the first timing information, the second timing information, and the bias.

A communication system is a communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body and a position of the mobile body, and a communicator configured to communicate with a communication device outside the mobile body using an antenna, in which the communicator is configured to set a reception sensitivity of the antenna when the position of the mobile body approaches to within a predetermined distance from the destination of the mobile body to be higher than a reception sensitivity of the antenna before the position of the mobile body approaches to within the predetermined distance.

Device localization (e.g., ultra-wideband device localization) may be used to provide coordinated outputs and/or receive coordinated inputs using multiple devices. Providing coordinated outputs may include providing partial outputs using multiple devices, modifying an output of a device based on its position and/or orientation relative to another device, and the like. In some cases, each device of a set of multiple devices may provide a partial output, which combines with partial outputs of the remaining devices to produce a coordinated output.

A logistics control system includes a server configured to receive information on signal strengths of the signal, which is transmitted from the logistics device, from the at least three base station, specify a departure area of the logistics device using at least three signal strengths, specify a first travel area to which the logistics device is moved using azimuth and travel distance information received from the logistics device on the basis of the departure area after a certain time elapses, specify a second travel area to which the logistics device is moved using at least three signal strengths, and specify a presence area where the first travel area and the second travel area overlap as a location to which the logistics device is moved.

Systems and methods for mapping location and characteristics about wireless emitters are described. The systems and methods advantageously use correlative receivers for observing the emissions from the wireless emitters without decrypting or decoding information included in the emissions from the wireless emitters to allow for tracking location and emitter class and type in real-time. The real-time geolocation and emitter class information for many receivers in a geographic area can be determined and overlaid on a map, for example.

A real-time locating system of the present disclosure may be used in connection with a particular facility and may include a tag associated with an object disposed within the facility. The tag may be configured to continuously emit radio frequency signals encapsulating a tag identifier and a battery status. The real-time locating system may also include a sensor positioned at a known location within the facility. The sensor may be configured to receive radio frequency signals from the tag and determine an associated signal strength. The real-time locating system may be configured to utilize the known location of the sensor and the signal strength of the radio frequency signal to determine the location of the tag and thus the object within the facility.

Geolocated information is communicated to a user based upon a position of smart device in a building as determined by optical recognition of a first visual identifier, a second visual identifier and a third visual identifier. A distance determined from each of the visual identifiers, as well as a direction of interest indicated by a user. A user interface is generated for display on a Smart Device based upon the position of the Smart Device and direction of interest.

Methods and Apparatus relating to environmental monitoring and control systems are discussed. More specifically, the present invention relates to methods and systems for monitoring temperature and other environmental conditions in a cold storage facility and tracking the locations and environmental conditions of a product throughout its cold storage life cycle using the environmental control system and smart devices in logical communication therewith. Tracked interactions with personnel in relationship to products in cold storage are also discussed.

A radiofrequency (RF) localization system can include an RF sensing component, a signal-processing module and a visualization element. A plurality of antennas mounted on a belt, or on a helmet, or at least one extendable antenna attached within a backpack could be used for the RF sensing component. The signal-processing module can receive an RF Signal-of-Interest (SOI), and can further compute localization information for the RF SOI such as line of bearing, signal-to-noise ratio (SNR), and SSID information. The visualization element can be an augmented reality (AR) visor mounted on the helmet, or AR glasses. The signal-processing module can be mounted to the helmet, visor, or glasses, as applicable. The RF sensing component, signal module and said visualization element can be worn by the user, and can cooperate to provide hands free RF localization information in an AR format to an end user.

Methods and device for use in a wireless device of reporting positioning measurements comprises receiving network assistance information from a network node. The network assistance information is for assisting the wireless device in performing Observed Time Difference Of Arrival (OTDOA), and comprises: a list of reference cells; a list of neighbor cells; and a rule for terminating Reference Signal Time Difference (RSTD) measurements. The method further comprises performing RSTD measurement between a cell in the reference cell list and a cell in the neighbor cell list. Upon determining the RSTD measurement satisfies the rule for terminating RSTD measurements, the method includes reporting the RSTD measurements to the network node. Upon determining the RSTD measurement does not satisfy the rule for terminating RSTD measurements, performing another RSTD measurement between the cell in the reference cell list and a cell in the neighbor cell list.
