Abstract: A method may include forming a mask layer on top of a first dielectric layer formed on a first source/drain and a second source/drain, and creating an opening in the mask layer and the first dielectric layer that exposes portions of the first source/drain and the second source/drain. The method may include filling the opening with a metal layer that covers the exposed portions of the first source/drain and the second source/drain, and forming a gap in the metal layer to create a first metal contact and a second metal contact. The first metal contact may electrically couple to the first source/drain and the second metal contact may electrically couple to the second source/drain. The gap may separate the first metal contact from the second metal contact by less than nineteen nanometers.

Abstract: A source donor supports inter-donor migration of an integrated access backhaul (IAB) node from the source donor to a target donor, where the source donor and the target donor corresponding to respective nodes of a radio access network (RAN), and when a user equipment (UE) is in communication with the RAN via the IAB-node. The source donor transmits, to the target donor, a handover request message related to the IAB-node; receives, from the target donor, a handover request acknowledge message including an IAB-node configuration related to the inter-donor migration of the IAB-node; provides the IAB-node configuration to the IAB-node; and transmits downlink data for the UE to the target donor, for forwarding to the UE via the IAB-node.

Abstract: This document describes methods and systems for user equipment (UE) context transfer over radio access network (RAN) paging. A first base station receives from a second base station a first message that includes a context that is associated with a user equipment while the user equipment was in an engaged mode with the second base station. The first base station transmits a second message that is a paging message to the user equipment and in response receives, from the user equipment, a third message that includes a resume message authentication code identifier. After the first base station verifies the third message using the resume message authentication code identifier, the first base station transmits, to the user equipment, a fourth message that enables the user equipment to resume the engaged mode with the first base station in accordance with the context.

Abstract: A user equipment (UE) receives, from a radio access network (RAN), conditional configuration information including (i) a configuration related to a base station or a cell, and (ii) a condition to be satisfied before the UE applies the configuration (2102). The UE determines a procedure to which the conditional information pertains (2104). The UE applies, during the determined procedure, the configuration if the condition is satisfied (2106).

Abstract: This document describes methods, devices, systems, procedures, and means of maintaining communication and signaling interfaces during network role transitions, such as a secondary node change or a handover. A source secondary base station holds a source donor Central Unit (Source CU) for its own Distributed Unit (source DU) and for the Distributed Unit(s) of the node base station(s) (node DU). The source secondary base station connects to the node base station via a first F1 interface. The node DU triggers handover of the node base station and connected User Equipment (UE) from the source secondary base station to a target secondary base station. The node base station creates Transport Network Layer (TNL) connectivity toward a target donor Central Unit (Target CU) and exchanges application layer configuration data with the Target CU via a wireless backhaul link implemented utilizing the TNL connectivity.

Abstract: This document describes techniques and apparatuses for handling radio resource control (RRC) cell group configuration. In implementations, a base station receives a first radio resource control message that requests a connection procedure between a user equipment and the base station, such as a radio resource control resume request or a radio resource setup request. In response to receiving the first radio resource control message, the base station generates a second radio resource control message that includes a cell-group-configuration information element that excludes a reconfiguration-with-sync information element. The base station then transmits the second radio resource control message to the user equipment. Afterward, the base station receives, from the user equipment, a third radio resource control message that indicates the connection procedure is complete.

Abstract: This document describes techniques and apparatuses for handling radio resource control (RRC) cell group configuration. In implementations, a base station (120) receives a first radio resource control message that requests a connection procedure between a user equipment (110) and the base station (e.g., 325, 425, 1325), such as a radio resource control resume request or a radio resource setup request. In response to receiving the first radio resource control message, the base station (120) generates a second radio resource control message that includes a cell-group-configuration information element that excludes a reconfiguration-with-sync information element (e.g., 330, 430, 1330). The base station (120) then transmits the second radio resource control message to the user equipment (110) (e.g., 335, 435, 1345). Afterward, the base station (120) receives, from the user equipment (110), a third radio resource control message that indicates the connection procedure is complete (e.g., 340, 440, 1350).

Abstract: This document describes methods, devices, systems, and means for determining configurations for the exchange of configuration information during network role transitions, such as a secondary node change or a handover. A secondary base station (123) node includes a central unit (CU) (410) and one or more distributed units (DU) (420). The secondary base station node is configured to receive an addition request message including configuration information and, based on the received configuration information, determine, at the CU (410) of the secondary base station (123), whether to apply a full configuration or a delta configuration. The CU (410) generates secondary cell group information, based on cell group configuration information received from the one or more DUs (420), and send an addition response message, including the generated secondary cell group information, to a master base station (122).
