Methods, systems, and devices for wireless communications are described. A wireless device may establish a radio resource control (RRC) connection over a wireless local area network (WLAN) link. For example, the wireless device may transmit a packet to an access point or WLAN termination that includes an RRC container including an RRC message for establishing (e.g., setting up, resuming) a connection with a centralized unit (CU). In some examples, the wireless device may additionally or alternatively be configured with dual connectivity over a WLAN link, including the addition, modification, and release of nodes associated with different radio access technologies. In such cases, the CU may configure connectivity with the WLAN, where the CU may configure a port number for each radio bearer via an RRC message transmitted over a direct link with the wireless device (e.g., via a distributed unit) or via the WLAN link.
