    IPC: H04W36/36

    CPC classification number: H04W36/362

    Abstract: The present invention relates to survival time aware mobility and presents handover procedures when considering survival time (ST) requirements. It proposes a mechanism and embodiments to allow a target cell to have the information relating to a joining UE's Survival Time requirements as well as the ST status during the handover procedure. In particular, the invention is aimed at being introduced into the mobility procedures: Baseline Handover (BHO), Conditional HO (CHO), and Dual Active Protocol Stack (DAPS) HO. In addition to the aggregated RAN architecture, the mobility procedures can be applicable to disaggregated RAN architecture, e.g., CU-DU split.

    Abstract: An apparatus is provided for use by a network agent element or function to conduct link layer information related processing. The apparatus is caused to receive first link layer related information from a neighboring network element or function, forward second link layer related information to a communication network control element or function, receive third link layer related information from a communication network control element or function, and forward fourth link layer related information to a neighboring network element or function. The second and fourth link layer related information are generated using first and third link layer related information, respectively. The second and third link layer related information is received and forwarded via a wireless connection path of a wireless communication network. The apparatus is connected to or part of the/or communication element or function, a communication network control element or function and a communication network data element or function.

    Abstract: Systems, methods, apparatuses, and computer program products for data transmission with stateless routing are provided. Certain embodiments may include a radio resource control (RRC)—less or RRC-based mechanism for short data transmission (SDT) in an RRC inactive state, where the mechanism may be performed without storing or establishing a UE context in a distributed unit (DU), for a UE served by a single CU-user plane (UP). Certain embodiments may include a RRC-less mechanism for SDT in an RRC inactive state, where the authentication of the user equipment (UE) may be performed at the UP using UP integrity protection (IP) in a CU-UP. Certain embodiments may include a RRC-based mechanism for SDT in an RRC inactive state, where the authentication of the UE may be performed at the UP using UP IP in a CU-UP and/or at the CP using CP IP in a CU-CP.
