INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report. ## Claims ### Claim 1 A method for wireless communication, comprising: establishing, at a first node, a connection with a network via a first path that includes at least a first relay node in a wireless communications network, wherein the first node is a user equipment (UE) or a mobile termination (MT) function within the wireless communications network; identifying, at the first node, at least a second path available for the connection with the network that includes at least a second relay node; determining, by the first node, a first network load associated with the first path that includes one or more units of data traffic that the first node is to transmit to the network, and a second network load associated with the second path that includes the one or more units of data traffic; and transmitting a report to the network based at least in part on a difference between the first network load and the second network load determined by the first node or a change in one or more of the first network load or the second network load determined by the first node. ### Claim 2 (depends on 1) The method of claim 1, wherein the first node connects with the network via an anchor node in the wireless communications network. ### Claim 3 (depends on 1) The method of claim 1, further comprising: receiving, from the network responsive to the report, an indication to switch the connection with the network from the first path to the second path. ### Claim 4 (depends on 1) The method of claim 1, wherein the first node, the first relay node, and the second relay node are integrated access and backhaul (IAB) nodes, and wherein one or more IAB nodes may be incorporated in one or more base stations in the wireless communications network. ### Claim 5 (depends on 1) The method of claim 1, wherein the first relay node and the second relay node are mobile termination (MT) functions in integrated access and backhaul (IAB) nodes. ### Claim 6 (depends on 1) The method of claim 1, wherein the first network load and the second network load are determined based at least in part on one or more of: a congestion of one or more nodes within the first path or the second path, a congestion of one or more links within the first path or the second path, a resource utilization of one or more nodes within the first path or the second path, a resource utilization of one or more links within the first path or the second path, a number of other nodes connected with an anchor node via one or more nodes within the first path or the second path, or any combinations thereof. ### Claim 7 (depends on 6) The method of claim 6, further comprising: receiving, at the first node, configuration information that includes network load information associated with one or more nodes within the wireless communications network, the one or more nodes including the first relay node and the second relay node. ### Claim 8 (depends on 7) The method of claim 7, further comprising: measuring one or more channel conditions associated with at least the first relay node and the second relay node;
