Information processing apparatus, information processing method, and non-transitory computer-readable storage medium
An information processing apparatus includes a specifying unit, an obtaining unit, and a display unit. The specifying unit specifies a first position of a communication apparatus viewed from the information processing apparatus by wireless communication with the communication apparatus. The obtaining unit obtains information representing a second position of a target viewed from the communication apparatus. The target is held by the communication apparatus, from the communication apparatus by the wireless communication. The display unit displays information representing a third position of the target viewed from the information processing apparatus based on the first position specified by the specifying unit and the second position represented by the information obtained by the obtaining unit.
GUIDED ALIGNMENT OF WIRELESS DEVICE ORIENTATION
Embodiments provide for guided alignment of the orientation of two wireless devices. A first wireless device is at a known position and a known orientation. A signal from a second wireless device is received via a plurality of receive elements of the first wireless device. The first wireless device measures phase differences of the signal at the plurality of receive elements, and determines locations of each of the second wireless device's transmit elements based on the differences. Based on the transmit element locations, and a known antenna layout of the second wireless device, an orientation of the second wireless device is determined. Based on differences between the determined orientation and the known orientation of the first wireless device, instructions for aligning the devices are generated. Once the devices are aligned, location estimates of a third wireless device are made by both the first wireless device and the second wireless device.
METHOD FOR TRANSMITTING, BY APPARATUS, CPM IN WIRELESS COMMUNICATION SYSTEM SUPPORTING SIDELINK, AND APPARATUS THEREFOR
Disclosed are, according to various embodiments, a method for transmitting, by a user equipment (UE), a first collective perception message (CPM) in a wireless communication system supporting a sidelink, and an apparatus therefor. Disclosed are the method and the apparatus therefor, the method comprising the steps of: obtaining first object information on surrounding objects through a sensor; receiving a second CPM including second object information; and transmitting the first CPM including the first object information and location information for the UE, wherein the second CPM further includes information on a location reliability of the second object information, the position information of the UE is corrected by applying an offset, based on the first object information and the second object information being object information for the same object, and the offset is determined by applying a ratio between a first position reliability related to the position information of the UE and the second position reliability included in the second CPM to a distance between an object position based on the first object information and an object position based on the second object information.

Communication system and method for operating 5G mesh network for enhanced coverage and ultra-reliable communication
A communication system includes a central cloud server to establish a primary communication path between a radio access network (RAN) node and one or more user equipment (UEs) via a first set of edge devices of a plurality of edge devices, where each edge device is configured as a mesh node of a mesh network. The central cloud server determines a plurality of secondary communication paths between the RAN node and the one or more UEs via different sets of edge devices. The central cloud server ranks each of the plurality of secondary communication paths in terms of one or more signal quality parameters and controls switching from the primary communication path to one or more secondary communication paths configured as backup communication paths within a threshold time to maintain a continuity in service to the one or more UEs for uplink and downlink communication.
METHOD, APPARATUS, AND SYSTEM FOR MAP RECONSTRUCTION BASED ON WIRELESS TRACKING
Methods, apparatus and systems for map reconstruction based on wireless tracking are described. In one example, a described system comprises: a sensor configured to collect sensing data in a venue and obtain a plurality of trajectories, and a processor. Each trajectory is a time series of spatial coordinates (TSSC) representing a path traversed by a respective object in the venue. Each TSSC is accompanied by at least one respective time series of sensing data (TSSD) collected while the respective object traverses the path in the venue. The processor is configured for: segmenting each TSSC and its accompanying at least one TSSD into segments, bundling the plurality of trajectories based on similarity measures between pairs of the segments, fusing the bundled trajectories to generate fused trajectories, computing a shape of the fused trajectories, and generating a map of the venue based on the computed shape.
UNAUTHORIZED TRACKING DEVICE DETECTION AND PREVENTION
Unauthorized tracking devices, including those that change their identification information periodically, are detected to protect an individual's privacy. A mobile device of a user detects a first advertisement signal from an unknown wireless device, the first advertisement signal containing information representative of the unknown device. Multiple advertisement signals may be received as the mobile device moves a distance greater than a broadcast range away from the location where the first signal was detected. Responsive to detecting a second advertisement signal containing the same identity information after the mobile device has moved at least the distance greater than the broadcast range away from the location where the first signal was detected, the system generates an interface on the mobile device. The generated interface indicates to a user of the mobile device the presence of an unknown device.
SYSTEMS AND METHODS FOR IDENTIFYING A SOURCE OF RADIO FREQUENCY INTERFERENCE IN A WIRELESS NETWORK
An interference detection system in a network determines that an unknown radio frequency (RF) interference source that causes RF interference experienced by a first wireless station is a persistent RF interference source over a plurality of time intervals in a selected time period. A predicted interference source location is identified for each time interval in the selected time period. An aggregated predicted interference source location is calculated based on the identified one or more predicted interference source locations.
