[0029] Wireless communication technologies are moving the world toward an increasingly connected and networked society. High-speed and low-latency wireless communications rely on efficient network resource management and allocation between user equipment and wireless access network nodes (including but not limited to base stations) . A new generation network is expected to provide high speed, low latency and ultra-reliable communication capabilities and fulfill the requirements from different industries and users.
[0030] In some wireless communication system with long term evolution (LTE) and / or new radio (NR) , a high speed dedicated network (HSDN) function / cell may be implemented. In some implementations, HSDN may be referred as a high-speed-railway dedicated network. The HSDN cell (or the HSDN-enabled cell) is implemented with special settings for a high-mobility-state user equipment (UE) to provide better quality of service (QoS) and / or better quality of experience (QoE) when the UE is in a special / high mobility state.
[0031] However, there are some issues / problems associated with utilizing HSDN function / cells. For example, HSDN cell information and configuration may only be configured by an operation, administration, and maintenance (OAM) . With more and more cells deploying the HSDN function and requiring configuration modifications, the load on the OAM to manage such a large number of HSDN cells is getting heavier and heavier. Thus, there is need for an efficient way to manage one or more HSDN functions / cells, so as to reduce the load on OAM and / or improve performance.
[0032] The present disclosure describes various embodiments for transmitting high speed dedicated network (HSDN) related information in a mobile communication system, addressing at least one of the issues / problems discussed in the present disclosure, thus increasing efficiency of managing HSDN cells, enabling future wireless communication system to provide improved performance to meet various demands of new generation wireless services in wireless communication systems.
[0033] Various embodiments in the present may allow a network (NW) to configure HSDN cells (e.g. turn on / off such function, exchange capability, etc. ) . In some implementations, when an HSDN-capable UE in a specific mobility state (e.g., high-mobility state) , the UE may always consider a HSDN cell to be of the highest priority compared to any other network-configured priorities. In some implementations, when a HSDN-capable UE is not in the high-mobility state, the UE may always consider HSDN cells to be of the lowest priority (i.e., lower than any other network-configured priorities) .
[0034] FIG. 1A shows an example of cellular wireless communication network 100 (also referred to as wireless communication system) that includes a core network 110, a radio access network (RAN) 120, and one or more user equipment (UE) 130. The core network 110 may include a user plane function (UPF) , which represents the data plane evolution of a control and user plane separation strategy. The UPF plays the important role in the process of data transfer by providing an interconnect point between the RAN 120 and the Data Network (DN) , for example, encapsulation and decapsulation of general packet radio service tunnelling protocol user plane (GTP-U) . The UPF may perform the functionalities including but not limited to serving as an anchor point for intra- / inter-radio access technology (RAT) mobility, packet routing and forwarding, traffic usage reporting, quality of service (QoS) handling for the user plane, downlink packet buffering and downlink data notification triggering.
[0035] The core network may include a session management function (SMF) , wherein the SMF performs the functionalities including but not limited to establishment, modification, and release of communication sessions, UE IP address allocation and management (including optional authorization functions) , selection and control of UPF, and downlink data notification. Each SMF may control one or more UPFs and is associated with a service area being a collection of UPF service areas of all UPFs under its control.
[0036] The RAN 120 further includes multiple base stations 122 and 124 (or referred as network nodes or RANs) . The base station 122 and one or more user equipment (UE) 130 communicate with uplink / downlink communication channels 140. The wireless communication network 100 may be implemented as, as for example, a 2G, 3G, 4G / LTE, 5G, 6G, or any future communication network. Correspondingly, each of the RANs / base stations 122 and 124 may be implemented as a 2G RAN / base station, a 3G RAN / nodeB, an LTE RAN / eNB, a 5G New Radio (NR) RAN / gNB, and / or a NG RAN. The UE 130 may be implemented as mobile or fixed communication devices for accessing the wireless communication network 100. The one or more UE 130 may include but is not limited to mobile phones, aerial UE (e.g., drone etc. ) , internet of things (IoT) devices, machine-type communications (MTC) devices, laptop computers, tablets, personal digital assistants, wearable devices, distributed remote sensor devices, roadside assistant equipment, and desktop computers. Alternative to the context of cellular wireless network, the RAN 120 and the principles described below may be implemented as other types of radio access networks, such as Wi-Fi, Bluetooth, ZigBee, and WiMax networks.
[0037] In the example wireless communication system 100 of FIG. 1A, the one or more UE 130 may connect with and establish a communication session with the base station 122. The communication session between the UE 130 and the base station 122 may utilize downlink (DL) and / or uplink (UL) transmission resources. The DL transmission resource carries data from the base station 122 to the UE 130, and the UL transmission resource carries data from the UE 130 to the base station 122. Under certain circumstances, for example when the base station 122 is unavailable or when the UE 130 moves into a coverage of the base station 124, the one or more UE 130 may connect with and establish a communication session with the base station 122, for example, during a handover process.
[0038] One or more UE, communicating with a base station, may be served by at least one cell. Each cell is associated with a coverage area. These cells may be alternatively referred to as serving cells. The coverage areas between cells may partially overlap. Each UE may be actively communicating with at least one cell while may be potentially connected or connectable to more than one cell. In the example of FIG. 1A, one or more UEs 130 may be served by one cell, whereas one or more UEs 132 may be served by another cell.
[0039] In some implementations, a UE may be served simultaneously by two or more cells. Each of the UE may be mobile and the signal strength and quality from the various cells at the UE may depend on the UE location and mobility.
[0040] In some implementations, a cell, serving a UE, may be alternatively referred to as a serving cell. One or more serving cells may be grouped into serving cell groups (CGs) . A serving cell group may be either a Master CG (MCG) or Secondary CG (SCG) . Within each type of cell groups, there may be one primary cell and one or more secondary cells. A primary cell in a MSG, for example, may be referred to as a PCell, whereas a primary cell in a SCG may be referred to as PScell. Secondary cells in either an MCG or an SCG may be all referred to as SCell. The primary cells including PCell and PScell may be collectively referred to as spCell (special Cell) . All these cells may be referred to as serving cells or cells. The term “cell” and “serving cell” may be used interchangeably in a general manner unless specifically differentiated. The term “serving cell” may refer to a cell that is serving, will serve, or may serve the UE. In other words, a “serving cell” may not be currently serving the UE. While the various embodiment described below may at times be referred to one of the types of serving cells above, the underlying principles apply to all types of serving cells in both types of serving cell groups.
[0041] Referring to FIG. 1B, a RAN / base station (e.g., gNB) (using 122 as non-limiting example) may have a central-distributed separated structure, which may include a central unit (CU) 160 and one or more distributed unit (DU) 171 and / or 172. The core network (e.g., 5GC) may communicate with the gNB via a NG interface between them. The gNB and another gNB may communicate via a Xn interface. The gNB-CU may communicate with the one or more gNB-DU via a F1 interface.
[0042] In some implementations, F1 interface is between a gNB-CU and a gNB-DU, providing an interconnection point between the gNB-CU and the gNB-DU.
[0043] In some implementations, Xn interface is between two RAN nodes, providing an interconnection point between the RAN nodes.
[0044] In some implementations, in the architecture of CU / DU split, a gNB may consist of a gNB Central Unit (gNB-CU) and one or more gNB Distributed Unit (gNB-DU) . A gNB-CU and a gNB-DU is connected via F1 interface. The gNB-CU is defined as a logical node hosting radio resource control (RRC) , SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. The gNB-DU is defined as a logical node hosting RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is partly controlled by gNB-CU. One gNB-DU supports one or multiple cells. One cell is supported by only one gNB-DU.
[0045] FIG. 1C shows another schematic diagram of a base station (e.g., gNB) 150. The gNB may have a central-distributed separated structure, which may include a central unit (CU) 160 and one or more distributed unit (DU) (for example 171 and / or 172) . The CU may include a control plane (gNB-CU-CP) 161 and one or more user plane (gNB-CU-UP) 162. The gNB-CU-CP 161 may be referred as CU-CP or CP, and the gNB-CU-UP 162 may be referred as CU-UP or UP. The CU-CP 161 may communicate with the one or more CU-UP 162 via an E1 interface between them. The CU-CP 161 may communicate with the one or more DU via a F1-C interface, and each of the one or more CU-UP 162 may communicate with the one or more DU via a F1-U interface.
[0046] In some implementations, a NG-RAN may also consist of a set of ng-eNBs, and an ng-eNB may consist of an ng-eNB-CU-CP, one or more ng-eNB-CU-UP (s) , and one or more ng-eNB-DU (s) . An ng-eNB-CU-CP and an ng-eNB-CU-UP is connected via the E1 interface. An ng-eNB-DU is connected to an ng-eNB-CU-CP via the W1-C interface, and to an ng-eNB-CU-UP via the W1-U interface. The various embodiments / implementations described in the present disclosure may also be applicable to ng-eNB and its corresponding E1 and W1 interfaces, if not explicitly specified otherwise.
[0047] In some implementations, a gNB may consist of a gNB-CU-CP, multiple gNB-CU-UPs and multiple gNB-DUs. The gNB-CU-CP is connected to the gNB-DU through the F1-C interface. The gNB-CU-UP is connected to the gNB-DU through the F1-U interface. The gNB-CU-UP is connected to the gNB-CU-CP through the E1 interface. One gNB-DU is connected to only one gNB-CU-CP. One gNB-CU-UP is connected to only one gNB-CU-CP.
[0048] In some implementations, for resiliency, a gNB-DU and / or a gNB-CU-UP may be connected to multiple gNB-CU-CPs by appropriate implementation. In some implementations, one gNB-DU can be connected to multiple gNB-CU-UPs under the control of the same gNB-CU-CP. In some implementations, one gNB-CU-UP can be connected to multiple DUs under the control of the same gNB-CU-CP.
[0049] In some implementations, the connectivity between a gNB-CU-UP and a gNB-DU is established by the gNB-CU-CP using bearer context management functions.
[0050] In some implementations, the gNB-CU-CP selects the appropriate gNB-CU-UP (s) for the requested services for the UE. In some implementations, multiple CU-UPs may belong to same security domain.
[0051] In some implementations, data forwarding between gNB-CU-UPs during intra-gNB-CU-CP handover within a gNB may be supported by Xn-U.
[0052] FIG. 1D further illustrates a simplified view of the various network layers involved in transmitting user-plane data (e.g., protocol data units (PDUs) ) from a transmitting device 181 to a receiving device 185 in the example wireless access network. FIG. 1D is not intended to be inclusive of all essential device components or network layers for handling the transmission of the PDUs. FIG. 1D illustrates that the data packaged by upper network layers 182 at the transmitting device 181 may be transmitted to corresponding upper layer 186 (such as radio resource control or RRC layer) at the receiving device 185 via Packet Data Convergence Protocol layer (PDCP layer, not shown in FIG. 1D) , radio link control (RLC) layer 183 and media access control (MAC) layer 184 of the transmitting device, the physical (PHY) layers of the transmitting and receiving devices and the radio interface, as shown as 189, and the media access control (MAC) layer 188 and RLC layer 187 of the receiving device. Various network entities in each of these layers may be configured to handle the transmission and retransmission of the PDUs.
[0053] In FIG. 1D, the upper layers (182 and / or 186) may be referred as layer-3 or L3, whereas the intermediate layers such as the RLC layer (183 and / or 187) and / or the MAC layer (184 and / or 188) and / or the PDCP layer (not shown in FIG. 1D) may be collectively referred to as layer-2, or L2, and the term layer-1 is used to refer to layers such as the physical layer and the radio interface-associated layers. In some instances, the term “low layer” may be used to refer to a collection of L1 and L2, whereas the term “high layer” may be used to refer to layer-3. In some situations, the term “lower layer” may be used to refer to a layer among L1, L2, and L3 that are lower than a current reference layer. Control signaling may be initiated and triggered at each of L1 through L3 and within the various network layers therein. These signaling messages may be encapsulated and cascaded into lower layer packages and transmitted via allocated control or data over-the-air radio resources and interfaces. The term “layer” generally includes various corresponding entities thereof. For example, a MAC layer encompasses corresponding MAC entities that may be created. The layer-1, for example, encompasses PHY entities. The layer-2, for another example encompasses MAC layers / entities, RLC layers / entities, service data adaptation protocol (SDAP) layers and / or PDCP layers / entities.
[0054] In some implementations for reselection priorities handling during cell reselection evaluation process, absolute priorities of different NR frequencies or inter-RAT frequencies may be provided to a UE in the system information, in the RRCRelease message, or by inheriting from another radio access technology (RAT) at inter-RAT cell (re) selection. In the case of system information, an NR frequency or inter-RAT frequency may be listed without providing a priority (i.e. the field cellReselectionPriority is absent for that frequency) . If any fields with cellReselectionPriority or nsag-CellReselectionPriority are provided in dedicated signalling, the UE may ignore any fields with cellReselectionPriority and nsag-CellReselectionPriority provided in system information.
[0055] In some implementations, when a UE is in camped normally state, if it supports slice-based cell reselection and has received the network slice (s) and network slice access stratum group (NSAG) information from non-access stratum (NAS) to be used for cell reselection, the UE may derive reselection priorities according to a pre-defined rule. In some implementations, the UE derives reselection priorities according to the pre-defined rule also in case a system information block (SIB) (e.g., SIB16) is not broadcast in the camped cell.
[0056] In some implementations, if a UE is in camped on any cell state, the UE may only apply the priorities provided by system information from current cell, and the UE preserves priorities provided by dedicated signalling and deprioritisationReq received in RRCRelease unless specified otherwise. When the UE in camped normally state, has only dedicated priorities other than for the current frequency, the UE may consider the current frequency to be the lowest priority frequency (i.e. lower than any of the network configured values) . When the HSDN capable UE is in high-mobility state, the UE may always consider the HSDN cells to be the highest priority (i.e., higher than any other network configured priorities) . When the HSDN capable UE is not in high-mobility state, the UE may always consider HSDN cells to be the lowest priority (i.e., lower than any other network configured priorities) . If the UE is configured to perform both NR sidelink communication and vehicle to everything (V2X) sidelink communication, the UE may consider the frequency providing both NR sidelink communication configuration and V2X sidelink communication configuration to be the highest priority. If the UE is configured to perform NR sidelink communication and not perform V2X communication, the UE may consider the frequency providing NR sidelink communication configuration to be the highest priority. If the UE is configured to perform V2X sidelink communication and not perform NR sidelink communication, the UE may consider the frequency providing V2X sidelink communication configuration to be the highest priority. If the UE is configured to perform ranging / sidelink positioning, the UE may consider the frequency providing ranging / sidelink positioning configuration to be the highest priority.
[0057] In some implementations, with respect to an orverall architecture of a network (NW) structure, an NG-RAN node may include a gNB or a ng-eNB. The gNB may provide NR user plane and control plane protocol terminations towards the UE. The ng-eNB may provide E-UTRA user plane and control plane protocol terminations towards the UE.
[0058] In some implementations, referring to FIG. 1E, gNBs and ng-eNBs are interconnected with each other by means of the Xn interface. The gNBs and ng-eNBs are also connected by means of the NG interfaces to the 5G core network (5GC) , more specifically to an access and mobility management function (AMF) by means of the NG-C interface and to the user plane function (UPF) by means of the NG-U interface.
[0059] FIG. 2 shows an example of electronic device 200 to implement a network base station (wireless communication node or gNB) or core network. The example electronic device 200 may include radio transmitting / receiving (Tx / Rx) circuitry 208 to transmit / receive communication with UEs and / or other base stations. The electronic device 200 may also include network interface circuitry 209 to communicate the base station with other base stations and / or a core network, e.g., optical or wireline interconnects, Ethernet, and / or other data transmission mediums / protocols. The electronic device 200 may optionally include an input / output (I / O) interface 206 to communicate with an operator or the like.
[0060] The electronic device 200 may also include system circuitry 204. System circuitry 204 may include processor (s) 221 and / or memory 222. Memory 222 may include an operating system 224, instructions 226, and parameters 228. Instructions 226 may be configured for the one or more of the processors 124 to perform the functions of the network node. The parameters 228 may include parameters to support execution of the instructions 226. For example, parameters may include network protocol settings, bandwidth parameters, radio frequency mapping assignments, and / or other parameters.
[0061] FIG. 3 shows an example of an electronic device to implement a terminal device 300 (for example, wireless communication terminal or user equipment (UE) ) . The UE 300 may be a mobile device, for example, a smart phone, or a mobile communication module disposed in a vehicle or a drone. The UE 300 may include communication interfaces 302, a system circuitry 304, an input / output interfaces (I / O) 306, a display circuitry 308, and a storage 309. The display circuitry may include a user interface 310. The system circuitry 304 may include any combination of hardware, software, firmware, or other logic / circuitry. The system circuitry 304 may be implemented, for example, with one or more systems on a chip (SoC) , application specific integrated circuits (ASIC) , discrete analog and digital circuits, and other circuitry. The system circuitry 304 may be a part of the implementation of any desired functionality in the UE 300. In that regard, the system circuitry 304 may include logic that facilitates, as examples, decoding and playing music and video, e.g., MP3, MP4, MPEG, AVI, FLAC, AC3, or WAV decoding and playback; running applications; accepting user inputs; saving and retrieving application data; establishing, maintaining, and terminating cellular phone calls or data connections for, as one example, internet connectivity; establishing, maintaining, and terminating wireless network connections, Bluetooth connections, or other connections; and displaying relevant information on the user interface 310. The user interface 310 and the inputs / output (I / O) interfaces 306 may include a graphical user interface, touch sensitive display, haptic feedback or other haptic output, voice or facial recognition inputs, buttons, switches, speakers and other user interface elements. Additional examples of the I / O interfaces 306 may include microphones, video and still image cameras, temperature sensors, vibration sensors, rotation and orientation sensors, headset and microphone input / output jacks, Universal Serial Bus (USB) connectors, memory card slots, radiation sensors (e.g., IR sensors) , and other types of inputs.
[0062] Referring to FIG. 3, the communication interfaces 302 may include a Radio Frequency (RF) transmit (Tx) and receive (Rx) circuitry 316 which handles transmission and reception of signals through one or more antennas 314. The communication interface 302 may include one or more transceivers. The transceivers may be wireless transceivers that include modulation / demodulation circuitry, digital to analog converters (DACs) , shaping tables, analog to digital converters (ADCs) , filters, waveform shapers, filters, pre-amplifiers, power amplifiers and / or other logic for transmitting and receiving through one or more antennas, or (for some devices) through a physical (e.g., wireline) medium. The transmitted and received signals may adhere to any of a diverse array of formats, protocols, modulations (e.g., QPSK, 16-QAM, 64-QAM, or 256-QAM) , frequency channels, bit rates, and encodings. As one specific example, the communication interfaces 302 may include transceivers that support transmission and reception under the 2G, 3G, BT, WiFi, Universal Mobile Telecommunications System (UMTS) , High Speed Packet Access (HSPA) +, 4G / Long Term Evolution (LTE) , 5G standards, 6G, and / or any other telecommunication standards. The techniques described below, however, are applicable to other wireless communications technologies whether arising from the 3rd Generation Partnership Project (3GPP) , GSM Association, 3GPP2, IEEE, or other partnerships or standards bodies.
[0063] Referring to FIG. 3, the system circuitry 304 may include one or more processors 321 and memories 322. The memory 322 stores, for example, an operating system 324, instructions 326, and parameters 328.

[0117] For step 620, the gNB-CU receives the HSDN related information in the F1AP message A from the gNB-DU and keeps / stores it locally. In some implementations, the gNB-CU responds with the F1AP message B. This F1AP message B may be either new defined F1AP message or existing one (e.g. F1 Setup Response message, gNB-DU Configuration Update Acknowledge message, etc. ) .
[0118] In some implementations, the F1AP message B may include a portion or all of the following HSDN related information / configuration: HSDN capability information used to indicate whether this gNB-CU supports the HSDN function, and / or at least one of the information introduced in step 610 and / or other embodiments in the present disclosure.

[0120] In some implementations, the step 620 is not needed, i.e., the F1AP message B is not needed, so that the gNB-DU sends the F1AP message A to the gNB-CU with the HSDN related information described in step 610 and the gNB-CU does not need to send F1AP message B.
[0121] In some implementations, the F1AP message B may not contain the detail information, so that the F1AP message B may be only used as acknowledge in HSDN function in this procedure.
[0122] In some implementations, the CU prefers to modify DU’s current HSDN state, so the CU sends the HSDN related configuration information to the DU, wherein information of the HSDN related configuration corresponds for the DU.

[0130] In some implementations, the F1AP message B may not be needed, so that the gNB-CU sends the F1AP message A to the gNB-DU with the HSDN configuration described in step 710 and the gNB-DU does not send F1AP message B to the gNB-CU.
[0131] In some implementations, in the Embodiment Set I, the RAN nodes may be at the same level, so the procedure is used to exchange their HSDN information with each other without further modification / advising; and / or in the Embodiment Set IV, the CU may send its HSDN capacity information to the DU, and may modify the DU’s HSDN state based on the received / stored DU’s HSDN information.
