Abstract: A gate all around transistor may be improved to provide better transistor circuits performance. In one example, a transistor circuit may include a dielectric or air gap as an insulator between the channels of the transistors in the circuit. In another example, a transistor may include a first channel surrounded by a first metal, a second channel surrounded by a second metal proximate to the first channel, and an insulator, such as a dielectric or air gap, between the first metal and the second metal. The insulator helps reduce the parasitic capacitance between the source/drain regions and the metal fill regions of the transistor.

Abstract: Efficient opportunistic communications in integrated access and backhaul (IAB) frameworks are provided allowing scheduling nodes and scheduled nodes to communicate within an allocated set of resources based on a different configuration than for non-opportunistic communications using a different set of resources. An additional set of available resources may be allocated for coordinated communications between a parent IAB-node and the child IAB-node. Resources within this available set are associated with a first configuration, and when prior coordination exists, the parent IAB-node and child IAB-node may communicate based on this first configuration over this available set of resources. However, when prior coordination does not exist, the parent IAB-node and child IAB-node may opportunistically communicate over the allocated set of resources based on a second configuration different than the first configuration.

Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device. The packet delivery window configuration may indicate a periodicity, offset, start time, end time, and/or duration of the delivery windows, among other information. Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.
