TECHNIQUES FOR TRIGGERING RANDOM ACCESS PROCEDURES AT PASSIVE DEVICES

WIPO Patent Application WO/2024/082205

A1

Methods, systems, and devices for wireless communication are described. A first network node may transmit control signaling to a second network node, which may indicate a grant of one or more resources and one or more parameters associated with a random access procedure to be performed at one or more passive network nodes that support backscatter communication. The second network node may transmit, in the one or more resources, a signal to activate the one or more passive network nodes. The second node may transmit command information to the one or more passive network nodes that may indicate the one or more parameters for the random access procedure. The first network node may transmit group control signaling to multiple energy harvesting network nodes. In such examples, the group control signaling may indicate a request for the multiple energy harvesting network nodes to perform a random access procedure.
