Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced ESL position determination and ESL position based notifications. In a first aspect, a method of wireless communication includes obtaining first position information for an asset of one or more assets associated with an electronic shelf label system based on first wireless information, and the first position information is associated with a first time. The method also includes obtaining second position information for the asset based on second wireless information, and the second position information is associated with a second time. The method further includes determining a notification for the asset based on the first position information, the second position information, the first time, and the second time. Other aspects and features are also claimed and described.

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: determining known positions of a first subset of ESL devices; receiving positioning measurements for each ESL device in a second subset of ESL devices; estimating a first position of each ESL device in the second subset based on the positioning measurements received for that ESL device and the known positions of the first subset; determining a positioning error associated with the first position of each ESL device in the second subset; and estimating a second position of each ESL device in the second subset based on the positioning error and additional positioning measurements received for that ESL device. Other aspects and features are also claimed and described.

Abstract: In some implementations, a ultra-wideband (UWB) device comprises a Global Anchor for a network of UWB anchors having a plurality of clusters and initiator anchors (Init-Anchors). The Global Anchor may obtain metric information comprising a centrality metric value of each Init-Anchor from information communicated to the Global-Anchor in a first control phase. The Global Anchor may determine a slot schedule for a second control phase, wherein: determining the slot schedule is based on the centrality metric values of the plurality of Init-Anchors; the slot schedule comprises an allocation of time slots of the second control phase among the plurality of Init-Anchors for wireless radio frequency (RF) communication; and the allocation of time slots includes a first set of time slots for upstream communication followed by a second set of time slots for downstream communication. The Global Anchor may send the slot schedule to an Init-Anchor of the plurality of Init-Anchors.
