With Third Generation Partnership Project (3GPP) dual connectivity (DC), a multiple receive/transmit (Rx/Tx) capable user equipment (UE) may be configured to utilize resources provided by two different nodes connected via a non-ideal backhaul, with one node providing New Radio (NR) access and the other node providing either Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) or NR access. One node may act as a master node (MN) and the node other as the secondary node (SN). The MN and SN are connected via a network interface and at least the MN is connected to the core network. The MN and/or the SN can be operated with shared spectrum channel access. Additional resources can be allocated on a user plane function (UPF) for uplink traffic for a dual connected UE; however, this may lead to a waste of UPF resources in some instances. Presented herein is a technique that provides for the ability to avoid such potential waste of UPF resources without imposing limitations NR-DC sessions.
