Abstract: A reconfigurable intelligent surface (RIS) in a radio network includes a plurality of passive elements which are controlled by a plurality of active elements distributed among the plurality of passive elements, wherein the plurality of active elements configure the reconfigurable intelligent surface to perform, based on at least one request message, at least one of sensing incident electromagnetic radiation harvested over at least one frequency range by the passive elements; and steering energy of the harvested electromagnetic radiation towards at least one energy harvesting device in the radio network. A network node is configured to select at least one reconfigurable intelligent surface in a radio network; and send at least one request message to the selected reconfigurable intelligent surface to cause the reconfigurable intelligent surface to steer harvested electromagnetic radiation within at least one frequency range toward at least one energy harvesting device in the radio network.

Abstract: Example embodiments of the present disclosure relate to reconfigurable intelligent surfaces (RIS) assisted communication. For example, RIS assisted blockage avoidance for low power internet of things (IoT) devices. An apparatus performs communication with a network device via a RIS, using at least one of a first channel or a second channel, wherein the first channel is for a transmission to the RIS and the second channel is for a reception from the RIS. In this way, it is possible to help reconnecting an IoT device with the network that has lost its connection with a gNB by using an RIS. It is also provided a low-cost and low-power connectivity solution for low-power IoT devices.
