Abstract

Systems and methods for releasing context(s) and / or connection(s) associated with a network node are provided herein. An Integrated Access Backhaul (IAB)-donor central unit (CU) receives an indication of a mobile termination context release associated with an IAB-node and coordinates the release of any user equipment / nodes served by the IAB-node and the release of F1 interface resource(s) and / or RRC connection(s) associated with the IAB-node.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 825,586, filed March 28, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates generally to wireless communications and wireless communications networks. Background technique [0004] Standardization bodies such as the 3rd Generation Partnership Project (3GPP) are studying potential solutions for efficient operation of Integrated Access Backhaul (IAB) and Radio Access Backhaul in New Radio (NR) networks. [0005] The IAB strives to reuse the existing functions and interfaces defined for the access. In particular, Mobile-Terminal (MT), gNB Distributed Unit (gNB-DU), gNB Central Unit (gNB-CU), User Plane Function (UPF), Access and Mobility Management Function (AMF) and Session Management Function (SMF) and the corresponding interfaces NR uu (between MT and gNB), F1, NG, X...
