Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) receiving from a network entity, a configuration message, wherein the configuration message includes a parameter specifying out-of-order delivery of data units from lower layers to upper layers of a protocol stack implemented on the UE, configuring a radio link control (RLC) layer of a protocol stack for out-of-order delivery based on the received configuration message, and notifying the network entity of the configuration of the RLC layer.

A random access control method can be applied to electronic devices and include: determining, when a medium access control layer receives a beam failure instance indication sent by a physical layer, whether a count value of a beam failure indication counter is greater than or equal to a preset value; detecting, when the count value of the beam failure indication counter is greater than or equal to the preset value, whether the electronic device is currently performing a random access; triggering, when the electronic device is not currently performing the random access, a new random access. According to the embodiments of the present disclosure, the user device can be prevented from occupying resources for a contention free random access (CFRA) for a long time.

Aspects of the disclosure generally relate to wireless communication. In some aspects, a wireless node may identify a first set of synchronization signal blocks (SSBs), within a synchronization signal (SS) burst set, that are used to indicate random access channel (RACH) occasions for a first wireless link type, the SS burst set including a second set of SSBs used to indicate RACH occasions for a second wireless link type; and transmit a RACH message in a RACH occasion corresponding to an SSB included in the first set of SSBs. In some aspects, a wireless node may configure an SS burst set to include a first set of SSBs to be used to indicate RACH occasions for a first wireless link type, and a second set of SSBs to be used to indicate RACH occasions for a second wireless link type; and transmit the SS burst set. Other aspects are provided.

Example data security processing methods and apparatus are described. One example method includes setting up a first PDU session. A first base station derives a first user plane key based on a received base key and performs security processing on user plane data in the first PDU session by using the first user plane key and a security algorithm. A second PDU session is set up. The first base station derives a second user plane key based on the base key and performs security processing on user plane data in the second PDU session by using the second user plane key and the security algorithm. The user plane key includes a user plane encryption key and/or a user plane integrity protection key.

Methods to support User Plane Separation (UPS) and User Plane Local offloading (UPL) for Fifth Generation (5G) non-Third Generation Partnership Project (3GPP) access are provided, including solutions for untrusted non-3GPP, trusted non-3GPP, and fixed/wireline communications via a Non-3GPP interworking Function (N3IWF) node. Three UPS solutions methods are provided, as well as UPL solution methods for 5G non-3GPP access involving N3IWFs with or without separated Control Plane (CP) and User Plane (UP) that are combined with a User Plane Function (UPF). Solutions to allow multiple CP entities to control the same single UP entity are also provided.

Method and apparatus for load balancing in a Cloud-radio access network (C-RAN) are disclosed. A method includes receiving control plane (CP) data associated with a user from a core network or a remote access point; and dispatching the CP data to a first user equipment (UE) virtualized network function component (VNFC) based on a first route.
