WIRELESS COMMUNICATION METHOD AND RELATED APPARATUSESTECHNICAL FIELD
[0001] The present application relates to wireless communication, and more particularly, to a wireless communication method and related apparatuses.BACKGROUND ART
[0002] In cellular wireless communication systems developed by the Third Generation Partnership Project (3GPP) , user equipment (UE) is connected by a wireless link to a radio access network (RAN) . The RAN includes a set of base stations (BSs) which provide wireless links to UEs located in cells covered by the base station and an interface to a core network (CN) which provides overall network control. The RAN and CN each conduct respective functions in relation to the overall network. The so-called 4G Long Term Evolution (LTE) system, namely, an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN) has been developed for a mobile access network where one or more macro-cells are supported by a base station known as an eNodeB or eNB (evolved NodeB) . Evolved from LTE, the so-called 5G or new radio (NR) systems where one or more cells are supported by a base station known as a gNB. Envisioned to succeed the current 5G networks, the 6G cellular system is the forthcoming generation of wireless communication technology.
[0003] 3GPP 6G network may be enhanced with a new type of communication plane, that is, the Data Plane. The Data Plane enables native AI and native sensing demand to be collaborative “on-path processing” between different network entities (i.e., not only between point-to-point, but also between any-to-any) over “indiscriminate network topology” to support metadata carriage and processing, in which the metadata are forwarded based on data services and data pipeline identifiers.
[0004] The DP relies on two sublayers of communication –DP control sublayer (signaling) and DP data sublayer (the actual data) . Data Plane is designed to support 6G data requirements, but 3GPP may finally change the name of the framework, i.e. the Data Plane may be replaced by something else. In this invention we focus on the description of the related function. To enable this service, one or more DP controllers are necessary. A new network function (NF) may be added to 6G Core Network. This network function controls Data Plane services. The DP specific NF may be referred to as Data Place Access Control (DPAC) (which may include DPAC-c and DPAC-d) . In the below text, the DPAC stands for any kind of DP controller, which may be specified by 3GPP once 6G normative work starts. 3GPP may finally agree to replace "DPAC" with "DMF" (Data Management Function) , "DPMF" (Data Plane Management Function) or something similar. The same applies to the gNodeB (gNB) and Mobility Management Function (MMF) or Access and Mobility Management Function (AMF) , which may also be changed, e.g. to xNB.
[0005] Any UE, RAN, NF and access stratum (AS) could be the DP data source or DP consumer to communicate with DP data sublayer to store or retrieve the data. Moreover, in order to support the on-path processing, the data pipeline is supported by the Data Plane. Any UE, RAN, NF and AS can be selected to become data pipeline contributor, depending on specific service requirement. Based on the service requirements, the DPAC may select suitable contributors.
[0006] UE and DPAC need to establish virtual communication interfaces, one for signaling to / from DPAC-c and the other one for exchanging the actual data with DPAC-d. UE typically will send the actual data to the DPAC-d data repository. Likewise, the UE may retrieve the data from the DPAC-d data repository.
[0007] The initial communications between UE and DPAC is enabled through the existing registration and packet data unit (PDU) session activation procedures. The lifecycle of the PDU session however is not necessarily as the same as the lifespan of UE-DPAC sessions for providing DP services. There would be a problem in establishing UE-DPAC communication channels.SUMMARY

[0024] Embodiments of the disclosure are described in detail with the technical matters, structural features, achieved objects, and effects with reference to the accompanying drawings as follows. Specifically, the terminologies in the embodiments of the present application are merely for describing the purpose of the certain embodiment, but not to limit the disclosure.
[0025] In this document, the term “ / ” should be interpreted to indicate “and / or. ” A combination such as “at least one of A, B, or C, ” “one or more of A, B, or C, ” “at least one of A, B, and C, ” “one or more of A, B, and C, ” or “A, B, and / or C” may be A only, B only, C only, A and B, A and C, B and C, or A and B and C, where any combination may contain one or more members of A, B, or C.
[0026] The following table includes some abbreviations used in some embodiments of the present application:
[0027] FIG. 1 shows a 5G architecture. Devices involved in the 5G architecture include UE, a Radio Access Network (RAN) , a User Plane Function (UPF) , a Data Network (DN) , an Access and Mobility Management Function (AMF) , a Session Management Function (SMF) , a Policy Control Function (PCF) , an Application Function (AF) , an Authentication Server Function (AUSF) , and Unified Data Management (UDM) . It is noted that this application may be applicable to the architecture shown in FIG. 1, but is not limited thereto. The application can also be applied to future communication system such as 6G system.
[0028] As shown in FIG. 1, the UPF plays a crucial role in the user plane architecture of the core network, specifically within the 5G Core (5GC) . Once the SMF provisions the UPF with PDRs, i.e. the rules for detecting and handling the packets, the UPF becomes responsible for managing and forwarding user plane data traffic between the RAN and external data networks, such as the Internet or private networks. Policy related network elements mainly include the PCF, which enforced the policy by communicating these to the AMF, the SMF, the RAN, and the UE. The PCF determines policy rules for network behaviors. This may include deciding how network resources are allocated, ensuring efficiency of network capabilities. The SMF is mainly responsible for executing session management tasks. The AMF is mainly responsible for executing access and UE mobility management tasks. Policy transmission and update of the two network elements (the AMF and the SMF) are managed and controlled by the PCF.
[0029] FIG. 2 illustrates that, in some embodiments, a user equipment (UE) 10 and one or more network elements or network devices 20 in a communication network system 30 according to an embodiment of the present application are provided. The communication network system 30 includes the UE 10 and one or more network elements or network devices 20. The UE 10 may include a memory 12, a transceiver 13, and a processor 11 coupled to the memory 12 and the transceiver 13. The one or more network elements or network devices 20 may include a memory 22, a transceiver 23, and a processor 21 coupled to the memory 22 and the transceiver 23. The processor 11 or 21 may be configured to implement proposed functions, procedures and / or methods described in this description. Layers of radio interface protocol may be implemented in the processor 11 or 21. The memory 12 or 22 is operatively coupled with the processor 11 or 21 and stores a variety of information to operate the processor 11 or 21. The transceiver 13 or 23 is operatively coupled with the processor 11 or 21, and the transceiver 13 or 23 transmits and / or receives a radio signal.
[0030] The processor 11 or 21 may include application-specific integrated circuit (ASIC) , other chipset, logic circuit and / or data processing device. The memory 12 or 22 may include read-only memory (ROM) , random access memory (RAM) , flash memory, memory card, storage medium and / or other storage device. The transceiver 13 or 23 may include baseband circuitry to process radio frequency signals. When the embodiments are implemented in software, the techniques described herein can be implemented with modules (e.g., procedures, functions, and so on) that perform the functions described herein. The modules can be stored in the memory 12 or 22 and executed by the processor 11 or 21. The memory 12 or 22 can be implemented within the processor 11 or 21 or external to the processor 11 or 21 in which case those can be communicatively coupled to the processor 11 or 21 via various means as is known in the art.
[0031] In some embodiments, the processor 11 of the user equipment 10 is configured to exchange for a data plane (DP) control sublayer with a network element using one type of radio bearer when the UE uses or is to use a DP service, and use the same type or another type of radio bearer for a DP data sublayer for transmission of DP data of the DP service. This can enable reliable signaling and data plane communication channels between the DP enabled UE and the DP controller (e.g., the DPAC (DPAC-c and DPAC-d) ) on the network side.
[0032] In some embodiments, the processor 21 of the network element or network device 20 is configured to exchange signaling for a data plane (DP) control sublayer with a user equipment (UE) using one type of radio bearer when a DP service is used or is to be used by the UE, and use the same type or another type of radio bearer for a DP data sublayer for transmission of DP data of the DP service. This can enable reliable signaling and data plane communication channels between the DP enabled UE and the DP controller (e.g., the DPAC (DPAC-c and DPAC-d) ) on the network side.
[0033] FIG. 3 is a flowchart of a wireless communication method 100 by a user equipment (UE) according to an embodiment of the present application. Referring to FIG. 3, the wireless communication method 100 includes the following steps. In Step 102, the UE exchanges signaling for a data plane (DP) control sublayer with a network element (e.g., a base station or gNB) using one type of radio bearer when the UE uses or is to use a DP service. In Step 104, the UE uses the same type or another type of radio bearer for a DP data sublayer for transmission of DP data of the DP service. In a first example, DP control signaling and DP data transmission may be carried by a DP-specific radio bearer (DPRB) . That is, a new type of DPRB may be used to support the DP signaling and data exchange. In a second example, the signaling of the DP control sublayer may be exchanged using signaling radio bearer (SRB) , while the DP data of the DP data sublayer may be transmitted using data radio bearer (DRB) . More specifically, the SRB is used to support the DP signaling between DPAC-c and UE, and the DRB is used to support the DP data between DPAC-d and UE. In a third example, both the signaling of the DP control sublayer and the DP data of the DP data sublayer may be carried using DRB. That is, the same DRB is used to support both the DP signaling and DP data. This can enable reliable signaling and data plane communication channels between the DP enabled UE and the DP controller (e.g., the DPAC (DPAC-c and DPAC-d) ) on the network side.
[0034] In some embodiments, in the case where the same DRB is used to support both the DP signaling and DP data, the UE may encapsulate the signaling of the DP control sublayer in a package with an address information of a DP controller, and send the package to the network using the DRB, which is then forwarded to the DP controller via a user plane function (UPF) . Likewise, the UE may receive a package from the network using the DRB, which is sent from a DP controller via a UPF, and decapsulate the package to obtain the signaling of the DP control sublayer. More specifically, when the UE wants to send DP signaling (e.g., a response to DP configuration) to the DPACA-c, the UE encapsulates the DP signaling in a package with the DPAC-c IP address and then sends the package to the network element using DRB. The network element may send the package to UPF, which directly forwards the package to the DPAC-c. When the DPAC-c sends the DP signaling (e.g., DP configuration) to the UE, the DPAC-c may send the DP signaling to UPF and the UPF sends the package to the UE via the network element. The UE decapsulates the package to obtain the DP signaling.
[0035] In some embodiments, the signaling of the DP control sublayer received from or transmitted to the network element may be carried by non-access stratum (NAS) signaling. More specifically, the network element may convert a UE-originated NAS message carrying the DP signaling into a service based interface (SBI) message with SBI format, and then send the SBI message to a DP controller (e.g., DPAC-c) . Moreover, the network element may convert a SBI message that is originated from a DP controller (e.g., DPAC-c) and carries the DP signaling, into a NAS message with NAS format, and then send the NAS message to the UE.
[0036] In some embodiments, the DP data of the DP data sublayer received from or transmitted to the network element may be carried by user-plane (UP) data. More specifically, the network element may encapsulate UE-originated user-plane (UP) data containing the DP data into a quick user datagram protocol (UDP) internet connection (QUIC) packet, and then send the QUIC packet to a DP controller (e.g., DPAC-d) . Moreover, the network element may decapsulate a QUIC packet that is originated from a DP controller (e.g., DPAC-d) to obtain the DP data, and then send the DP data to the UE via user plane.
[0037] In some embodiments, the DP data of the DP data sublayer received from or transmitted to the network element may be encapsulated in a quick user datagram protocol (UDP) internet connection (QUIC) packet. For example, the UE sends the QUIC packet to the network element and / or receives the QUIC packet from the network element, where the DP data are encapsulated in the QUIC packet. In some embodiments, the DP data of the DP data sublayer received from or transmitted to a network function (NF) may be encapsulated in a QUIC packet. For example, the network element sends the QUIC packet to the NF (e.g., DPAC-d or other NF) and / or receives the QUIC packet from the NF (e.g., DPAC-d or other NF) , where the DP data are encapsulated in the QUIC packet.
[0038] In some embodiments, the UE may send a message used to indicate the network element that the signaling of the DP control sublayer is destinated to a DP controller. More specifically, a new NAS message type may be provided to indicate to the network element that the destination NF for this UE-originated NAS message is DPAC-c. In some embodiments, the UE may receive a message used to indicate the UE that the signaling of the DP control sublayer is originated from a DP controller. More specifically, a new NAS message type may be provided to indicate to the UE this is a DPAC-originated message.
[0039] In some embodiments, if no radio bearer is available for the UE, the UE may wait until a necessary type of radio bearer becomes active or available. In some embodiments, the DP service may use one of existing PDU sessions, and the PDU session used for the DP service is unable to be deactivated during the DP service is used. In some embodiments, the DP service may use a DP-specific PDU session. Different network slices may be applied for the DP-specific PDU session activated for the DP service and PDU sessions activated for non-DP services.
[0040] FIG. 4 is a flowchart of a wireless communication method 200 by a network element according to an embodiment of the present application. Referring to FIG. 4, the wireless communication method 200 includes the following steps. In Step 202, the network element (e.g., a base station or gNB) exchanges signaling for a data plane (DP) control sublayer with a user equipment (UE) using one type of radio bearer when a DP service is used or is to be used by the UE. In Step 204, the network element uses the same type or another type of radio bearer for a DP data sublayer for transmission of DP data of the DP service. In a first example, DP control signaling and DP data transmission may be carried by a DP-specific radio bearer (DPRB) . That is, a new type of DPRB may be used to support the DP signaling and data exchange. In a second example, the signaling of the DP control sublayer may be exchanged using signaling radio bearer (SRB) , while the DP data of the DP data sublayer may be transmitted using data radio bearer (DRB) . More specifically, the SRB is used to support the DP signaling between DPAC-c and UE, and the DRB is used to support the DP data between DPAC-d and UE. In a third example, both the signaling of the DP control sublayer and the DP data of the DP data sublayer may be carried using DRB. That is, the same DRB is used to support both the DP signaling and DP data. This can enable reliable signaling and data plane communication channels between the DP enabled UE and the DP controller (e.g., the DPAC (DPAC-c and DPAC-d) ) on the network side. Other details of the method 200 may be referred to the method 100 described above and are not repeated herein.
[0041] For leading to a better understanding of this invention, exemplary embodiments are illustrated below.
[0042] Embodiment 1. Holding OFF till UE-gNB radio bearer becomes active
[0043] It is assumed the Data Plane information is not time critical. When UE needs to send any kind of DP info via DP control sublayer and / or DP data sublayer, if no radio bearer is available for the UE, the UE shall wait until necessary type of a radio bearer becomes active / available. Only after this will the UE be able to send the DP specific data. It is noted that in the Embodiment 1 the only impact on 3GPP specifications may be adding the above statement to 6G descendant of the 3GPP TS 23.501 (or something similar) .
[0044] Embodiment 2. Modifying the management of the existing PDU session
[0045] In the Embodiment 2, it is relied on DP services using one of the existing PDU sessions. The caveat is, the PDU session cannot be deactivated for the whole duration of the UE-DPAC communications and therefore the PDU session deactivation triggers need to be revisited. According to 3GPP TS 23.501, PDU Sessions are set up when requested by the UE, and can be modified or released at the request of either the UE or 5GC. These operations use NAS SM signaling exchanged over the N1 interface between the UE and the SMF. When an Application Server requests it, the 5GC can send a trigger to a specific application running on the UE. Upon receiving this trigger, the UE delivers it to the designated application, which may then establish a PDU Session to a specific DNN. It should be noted that apart from the need for other changes, this embodiment may also require changes to the triggers of the PDU session deactivation, that is, current PDU session deactivation triggers may have to be revised accordingly.
[0046] Embodiment 3. Activating DP specific network slice, i.e. DP specific PDU session
[0047] In the Embodiment 3, it is relied on activating a DP specific PDU session, because typically there will be a QoS requirement mismatch between the DP specific PDU session and the PDU session activated for another reason (for non-DP services) . To resolve this, differentiated QoS flows must be applied, i.e. different network slices shall be used. According to 3GPP TS 23.501, a PDU Session belongs to one and only one specific Network Slice instance per PLMN. Different Network Slice instances do not share a PDU Session, though different Network Slice instances may have slice-specific PDU Sessions using the same DNN. Therefore, when applying the Embodiment 3, DP specific PDU session with DP specific Network Slice instance may be allocated.
[0048] Embodiment 4. New interfaces, adding intelligence to gNB
[0049] a) New interfaces need to be specified between a DPAC and a gNB. The DPAC shall become capable of requesting the gNB to establish a new type or new types of radio bearer (s) between the UE and the gNB. One bearer will be used to exchange DP control sublayer (signaling) messages between the UE and the DPAC-c, while the same or another radio bearer type will be used for the DP data sublayer, as described below.
[0050] i. New type of DPRB to support the DP signaling and data exchange.
[0051] ii. Using SRB to support the DP signaling configuration between DPAC-c and UE. Using DRB to support the DP data between DPAC-d and UE.
[0052] iii. Using the same DRB to support both the DP signaling and DP data. If using the DRB to carry the DP signaling, when the DPAC-c sends the DP signaling configuration to the UE, the DPAC-c will first send the DP signaling to UPF and the UPF sends the package to the UE via RAN. When the UE wants to send the DP signaling (e.g. DP signaling configuration response) to the DPACA-c, UE needs to know the DPAC-c IP address first and sends the package to the RAN using DRB. The RAN sends the package to UPF. The UPF directly forwards the package to DPAC-c.
[0053] b) The gNB needs to become more intelligent by telling apart:
[0054] i. Ordinary NAS signaling from the UE to DPAC-c from those to the AMF. The gNB shall send ordinary NAS messages to the AMF, while it shall send the NAS messages, which contain DP signaling to the DPAC-c. The same applies to the reverse direction, the gNB shall handle the downlink signaling differently (see the below points 'c. i' and 'd. i') .
[0055] ii. User Plane (UP) data from UE to UPF from DP data from UE to DPAC-d. The gNB shall send the UP data to the UPF, while it shall send the DP data to the DPAC-d. The same applies to the reverse direction (see the below points 'c. ii' and 'd. ii') .
[0056] c) The gNB needs to become more intelligent by converting the data formats when communicating with the DPAC-and DPAC-d.
[0057] i. The gNB shall convert the UE-originated NAS messages, which contain DP signaling to SBI format (OpenAPI) , before sending these to the DPAC-c.
[0058] ii. The gNB shall encapsulate the UE-originated UP data into a QUIC packet, before sending these to the DPAC-d.
[0059] d) The gNB needs to become more intelligent by converting the data formats when communicating with the UE.
[0060] i. The gNB shall convert the DPAC-originated SBI messages from OpenAPI format into NAS format, before sending these to the UE.
[0061] ii. The gNB shall decapsulate the QUIC packet, before sending the data to the UE.
[0062] e) New signaling interface between the DPAC-c and gNB is provided to configure the gNB to establish a data pipeline connection between the UE and gNB. DPAC-c needs to communicate with the PCF first to determine the connection policy and then trigger the gNB configuration for establishing data plane connectivity between the UE and gNB. A new radio bearer type may be required for the data plane communications between the UE and the gNB. Alternatively, the same radio bearer that is used for the signaling can be reused for the UE to DPAC-d connection. After the connection is established, the following call flow is enabled.
[0063] i. UE sends the QUIC packet to the gNB.
[0064] ii. The gNB needs to be able to understand the received data, process it and send it to the next hop within a QUIC packet. The next hope is typically the DPAC-d, but in principle it can be any NF.
[0065] It is also noted that a new message type may be provided to indicate to the gNB that the destination NF for this UE-originated NAS message is DPAC-c. So, the gNB shall convert the message into SBI format (see the above bullet point 'c. i') .
[0066] It is also noted that a new message type may be provided to indicate to the UE this is a DPAC-originated message (i.e. it is not coming from e.g. the AMF) . Therefore, the gNB has converted the received SBI message into the NAS format (see the above bullet point 'd. i') .
[0067] FIG. 5 is a block diagram of an example system 700 for wireless communication according to an embodiment of the present application. Embodiments described herein may be implemented into the system using any suitably configured hardware and / or software.

The processors may be coupled with the memory / storage and configured to execute instructions stored in the memory / storage to enable various applications and / or operating systems running on the system.
[0068] The baseband circuitry 720 may include circuitry such as, but not limited to, one or more single-core or multi-core processors. The processors may include a baseband processor. The baseband circuitry may handle various radio control functions that enables communication with one or more radio networks via the RF circuitry. The radio control functions may include, but are not limited to, signal modulation, encoding, decoding, radio frequency shifting, etc. In some embodiments, the baseband circuitry may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry may support communication with an evolved universal terrestrial radio access network (EUTRAN) and / or other wireless metropolitan area networks (WMAN) , a wireless local area network (WLAN) , a wireless personal area network (WPAN) . Embodiments in which the baseband circuitry is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.
[0069] In various embodiments, the baseband circuitry 720 may include circuitry to operate with signals that are not strictly considered as being in a baseband frequency. For example, in some embodiments, baseband circuitry may include circuitry to operate with signals having an intermediate frequency, which is between a baseband frequency and a radio frequency. The RF circuitry 710 may enable communication with wireless networks using modulated electromagnetic radiation through a non-solid medium. In various embodiments, the RF circuitry may include switches, filters, amplifiers, etc. to facilitate the communication with the wireless network. In various embodiments, the RF circuitry 710 may include circuitry to operate with signals that are not strictly considered as being in a radio frequency. For example, in some embodiments, RF circuitry may include circuitry to operate with signals having an intermediate frequency, which is between a baseband frequency and a radio frequency.
[0070] In various embodiments, the transmitter circuitry, control circuitry, or receiver circuitry discussed above with respect to the user equipment, eNB, or gNB may be embodied in whole or in part in one or more of the RF circuitry, the baseband circuitry, and / or the application circuitry. As used herein, “circuitry” may refer to, be part of, or include an Application Specific Integrated Circuit (ASIC) , an electronic circuit, a processor (shared, dedicated, or group) , and / or a memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and / or other suitable hardware components that provide the described functionality. In some embodiments, the electronic device circuitry may be implemented in, or functions associated with the circuitry may be implemented by, one or more software or firmware modules. In some embodiments, some or all of the constituent components of the baseband circuitry, the application circuitry, and / or the memory / storage may be implemented together on a system on a chip (SOC) . The memory / storage 740 may be used to load and store data and / or instructions, for example, for a system.
