Abstract: This disclosure provides systems, methods, and devices for Electronic Shelf Label (ESL) systems that support positioning of ESL devices. In a first aspect, a method includes: transmitting, to each ESL device in a group of ESL devices deployed within an environment via a wireless network associated with the environment, a command to emit one or more flashes of light over a flash interval associated with the group; receiving, from a mobile device via the wireless network, visual data collected for the group by a camera during the flash interval; detecting, within the visual data, the one or more flashes emitted by each ESL device in the group over the flash interval; and determining a location within the environment of each ESL device in the group based on the one or more flashes emitted by each ESL device in the visual data. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices that support converting position information from a device to positional descriptions with respect to descriptional layouts of assets at a location. In a first aspect, a method of wireless communication includes obtaining position information associated with a user equipment (UE) and retrieving one or more frames of a survey video of a location that correspond to an estimated position of the UE. The estimated position is based on the position information. The method includes extracting a set of features from the one or more frames and outputting a description of the estimated position with respect to a descriptional layout of assets at the location based on one or more descriptions identified from the descriptional layout. The one or more descriptions are identified based on the set of features. Other aspects and features are also claimed and described.
