Description

[Technical Field]

[0001] This application relates to the field of communications. [Background technology]

[0002] The coverage problem is a fundamental issue in cellular network allocation. Mobile providers employ different types of nodes in their allocations to provide comprehensive coverage. While a common, full-protocol-stack cell allocation is naturally optimal, it is not always feasible (e.g., lack of backhaul links) or economically feasible. Therefore, mobile providers are considering using new types of nodes to increase the flexibility of their network allocations. For example, 3GPP R16 and R17 introduced a new node type that does not require a wired backhaul, namely, Integrated Access Backhaul (IAB). Another type of node is the radio frequency repeater (RF repeater). Radio frequency repeaters are typically non-generative and simply amplify and forward (AF) all received signals. Radio frequency repeaters have been widely applied and allocated in 2G, 3G, and 4G, supplementing the coverage provided by common, full-protocol-stack cells.

[0003] 3GPP (registered trademark) R17 introduces radio frequency repeaters to NR (New Radio) to increase the coverage area of ​​NR cellular network allocation. Figure 1 is a schematic diagram of a simple radio frequency repeater. Radio frequency repeaters are usually full-duplex and cannot distinguish between uplink and downlink transmissions. The advantages are low cost, easy allocation, and no increase in latency. The disadvantage is that noise is also amplified, increasing interference with the signal.

[0004] It should be noted that the introduction of the above technical background is merely for the purpose of providing a clear and complete explanation of the technical solutions of the present application and for the purpose of facilitating the understanding of persons skilled in the art, and the mere mention of these technical solutions in the background section of the present application does not constitute recognition that the technical solutions are publicly known to persons skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors have discovered that NR radio frequency repeaters standardize radio frequency and electromagnetic compatibility (EMC) requirements and must also consider the FR1 (Frequency Division Duplex (FDD) and Time Division Duplex (TDD)) and FR2 (TDD) bands. The radio frequency repeater does not need to perform adaptive beamforming for the UE. It also does not consider various factors that can improve performance. FR1 (frequency range 1) and FR2 (frequency range 2) are 5G NR band ranges, corresponding to the low and high band ranges, respectively.

[0006] To optimize system performance, including reducing interference and increasing coverage, network-controlled repeaters (NC repeaters, also known as smart repeaters) capable of receiving and processing side control information from the network have been proposed and recognized as an effective solution for enhancing network topology. While they represent an enhancement to traditional radio frequency repeaters, the network integration of network-controlled repeaters, including how to dynamically control them, has not yet been standardized.

[0007] To address at least one of the above problems, an embodiment of the present invention provides a method and apparatus for integrating a network of nodes. [Means for solving the problem]

[0019] These and other features of the present application will become apparent from the following specification, taken in conjunction with the accompanying drawings. While the specification and the accompanying drawings specifically disclose certain embodiments of the present application, which represent some of the embodiments in which the principles of the present application may be employed, it is to be understood that the present application is not limited to the described embodiments, but on the contrary, the present application includes all modifications, variations, and equivalents falling within the scope of the appended claims.

[0021] In the examples of this application, the singular forms "one" or "the" should be understood to include the plural form and broadly mean "one" or "a group," and should not be limited to the meaning of "one." Furthermore, unless the context clearly indicates otherwise, "the" should be understood to include not only the singular form but also the plural form. Furthermore, unless the context clearly indicates otherwise, the term "according to" should be understood to mean "at least in part depending on ...," and the term "based on" should be understood to mean "based at least in part on ...."

[0022] In the present embodiments, the term "communications network" or "wireless communication network" may refer to a network conforming to any of the following communications standards, such as Long Term Evolution (LTE), Advanced Long Term Evolution (LTE-A), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0023] Furthermore, communication between devices in the communication system can be performed according to any stage of communication protocol, for example, but not limited to, communication protocols 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, and future 5G, New Radio (NR), etc., and / or other currently known or future developed communication protocols.

[0024] In the present embodiment, the term "network device" refers to a device that connects a terminal device to a communication network and provides services to the terminal device in a communication system, for example. Network devices include, but are not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadband transmitter, a mobile management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0025] Base stations include, but are not limited to, Node Bs (NodeBs or NBs), evolved Node Bs (eNodeBs or eNBs), and 5G base stations (gNBs), and may further include remote radio heads (RRHs), remote radio units (RRUs), relays, or low-power nodes (e.g., femeto, pico, etc.). Furthermore, the term "base station" may include some or all of the functions thereof, and each base station may provide communication coverage for a specific geographic area. The term "cell" may refer to a base station and its coverage area, which is determined by the context in which the term is used.

[0026] In the present embodiment, the term "User Equipment" (UE) refers to a device that accesses a communication network and receives network services via network equipment, and is also referred to as "Terminal Equipment" (TE). The terminal equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber, a subscriber station (SS), an access terminal (AT), a station, etc.

[0027] Terminal devices include, but are not limited to, cellular phones, personal digital assistants (PDAs), modems, wireless communication devices, handheld devices, machine-type communication devices, laptop computers, cordless phones, smartphones, smart watches, digital cameras, etc., and may further include IAB-MTs, etc.

[0028] Furthermore, in scenarios such as the Internet of Things (IoT), the terminal equipment can also be a monitoring or measuring device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0029] 2 is an exemplary structural schematic diagram of a network-controlled repeater. As shown in FIG. 2, the network-controlled repeater 20 can be divided into two parts. One part realizes some UE functions and is used for communication with a gNB 21. This part can be referred to as a mobile termination (MT) 22, but the present application is not limited thereto and can have other naming schemes. The other part realizes radio frequency functions, i.e., the repeater's amplification and forwarding function. This part can be referred to as a radio unit (RU) 23, but the present application is not limited thereto and can have other naming schemes, just like the MT.

[0030] As shown in Figure 2, the link between the gNB 21 and the MT 22 is a control link or control path, and also a fronthaul link. Through this control link, the gNB 21 can configure the network control repeater 20 with side control information, such as TDD configuration, switching information, and RU beamforming information. This control link can be based on the existing Uu interface. The MT 22 applies this configuration information to the RU (i.e., the AF module) 23 through the internal operation of the network control repeater 20. Side control refers to the network equipment (gNB 21) originally intending to control the RU 23, but because there is no direct interface between the network equipment (gNB 21) and the RU 23, the network equipment (gNB 21) achieves control over the RU 23 through the control interface with the MT 22.

[0031] As shown in Figure 2, the access link from the gNB 21 to the general UE 24 is referred to as an AF link, or data path, because it undergoes signal amplification and forwarding by the network-controlled repeater 20. The network-controlled repeater 20 is transparent to the UE 24, and the UE 24 is likely unaware of the existence of the network-controlled repeater 20. The data path (e.g., using the FR2 band) carries analog uplink / downlink signals from or issued to the UE 24. The data path essentially passes through analog signals. The data path is entirely controlled by the gNB 21 (or a distributed unit (DU)) via a control path.

[0032] The inventors have discovered that the main advantages of network-controlled repeaters are a simpler protocol stack and network integration compared to traditional relays, IAB-DUs (integrated access and backhaul-distributed units) and gNBs, and that gNB side control enables more efficient AF operation, for example, by dynamically modifying the repeater's TX / RX (transmit and receive state), reducing unnecessary noise amplification and enabling transmission and reception with better spatialized directionality.

[0033] In addition, the possible technical directions for network-controlled repeaters are as follows: the design content of side control information includes basic designs such as beamforming information configuration, timing, and TDD configuration; other design aspects include transmitter / receiver switching (on-off), bandwidth information, power control, same-frequency related issues, and radio frequency requirements; the signals and configurations used to carry side control information must be researched and confirmed; in addition to side control information, the management of network-controlled repeaters must also be standardized, including, for example, authentication / empowerment and interference management.

[0034] However, as mentioned above, there is no standardization of how to dynamically control the network integration of network control repeaters.

[0035] Various embodiments of the present application will be described below with reference to the accompanying drawings, which are merely illustrative and not limiting of the present application.

[0036] In the embodiments of the present application, for convenience of explanation, a node allocated in a network to improve network coverage or user performance is referred to as a first node, which may be the network control repeater 20, a smart repeater (SR), or a reconfigurable intelligent surface (RIS), and the name is not limited in the present application. Also, for convenience of explanation, a unit that realizes the MT function in the first node is referred to as a first unit, and a unit that realizes the RU function in the first node is referred to as a second unit.

[0037] Example of the first aspect In this embodiment, a method for integrating a network of nodes is provided, which will be explained from the side of the first node.

[0038] FIG. 3 is a schematic diagram of a node network integration method in an embodiment of the present application. Referring to FIG. 3, the method includes: 301: A first unit of a first node accesses a network; 302: A first unit of the first node reports capability information to a network device; 303: A first unit of the first node logs in and empowers a core network through the network device; 304: A second unit of the first node starts up.

[0039] It should be noted that the above-mentioned attached drawing 3 is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of each operation can be adjusted as appropriate, and further, other operations can be added or some operations can be deleted. Those skilled in the art can make appropriate modifications according to the above content, without being limited to the description of the attached drawing 3.

[0040] In the present embodiment, as described above, the first node includes a first unit and a second unit, the first unit is a unit for configuring the second unit in the first node, and the second unit is a unit for transmitting signals between the network device and the terminal device in the first node. The above network integration process can effectively integrate the network and dynamically manage and control the second unit of the first node, thereby realizing an enhanced network coverage and providing better services to users.

[0041] In the present embodiment, the first unit and the second unit may be two collocated units in the first node as shown in Fig. 2, but the present invention is not limited thereto, and the second unit may be a single entity in the first node. For example, in the entire network, the first node acts as a special UE, accessing and managing RRC (Radio Resource Control) according to conventional UE behavior, and the second unit is not a collocated part but an entity within the UE, used to amplify and forward frequency signals.

[0042] In one set of embodiments, the first unit accessing the network includes the first unit selecting and accessing a network device supporting the first node based on air interface indication information of the candidate network devices.

[0043] In the above embodiment, the first unit connects to the network as a general UE, and the initial access process can be the same as that of a general UE. The difference from a general UE is that the first unit selects and accesses a network device that supports the first node based on the air interface indication information of the candidate network devices. The air interface information can be one piece of information added to SIB1, such as NCR-support, which is used to indicate whether the network device supports the first node type, but the present application is not limited thereto.

[0044] In one set of embodiments, the first unit reporting capability information to the network equipment includes the first unit sending a first message to the network equipment, the first message including information to indicate the capabilities of the first node and / or the type of the first node (e.g., whether it is a special UE, whether it is an NCR, whether it includes the second unit, etc.).

[0045] In the above embodiment, the first message may be an RRC Setup Complete message. For example, the RRC Setup Complete message may include an indication of the first node, for example, referred to as ncr-NodeIndication, and the network device may select an access and mobility management function (AMF) supporting the first node type for the first node based on the indication. However, the present application is not limited thereto, and the first message may be other messages.

[0046] In this embodiment, operation 303 is optional. If it is necessary to log in and empower the core network, operation 303 can be performed, so that the core network logs in and empowers the first node and notifies the network equipment of the result.

[0047] In this embodiment, after the second unit is powered on in 304, the repeater's AF function is immediately initiated to amplify and forward signals between the network device and the terminal device.

[0048] In this embodiment, in a series of embodiments, the first unit of the first node further establishes an operation, administration and maintenance (OAM) connection with an OAM server.

[0049] In one example, the first unit can establish an OAM connection with an OAM server using a protocol data unit (PDU) session.

[0050] For example, the first unit may establish a data radio bearer (DRB) for transmitting OAM data, i.e., transmit the OAM data as user plane data of the first unit. This type of scheme requires establishing a PDU session and a Uu interface data bearer for the first unit to transmit the OAM data. Multiple DRBs may be established between the first unit and the network device to transmit different types of OAM data.

[0051] In this example, the OAM data protocol stack of the first node may include a physical layer, a MAC layer, an RLC layer, a PDCP layer, an SDAP layer, and an OAM layer, with the OAM layer located above the SDAP layer.

[0052] FIG. 4 is an exemplary schematic diagram of an OAM data protocol stack. As shown in FIG. 4, an MT (i.e., a first unit) of a network control repeater 40 (i.e., a first node) establishes an OAM connection with an OAM server 41 via a PDU session.

[0053] In another example, the first unit establishes an OAM connection with an OAM server over the IP layer.

[0054] For example, the first node generates IP-based OAM packets and routes them from the network device to the OAM server via a conventional TCP / IP protocol stack. Downstream OAM data sent by the OAM server to the first node can be sent directly to the network device via an IP router, and the network device forwards it to the first node after receiving it. After receiving the downstream OAM data, the first node delegates its processing to a higher layer.

[0055] In this example, the OAM data protocol stack of the first node may include an L1 layer, an L2 layer, an IP layer, a TCP layer, and an OAM layer, with the OAM layer sitting on top of the TCP layer.

[0056] FIG. 5 is another exemplary schematic diagram of an OAM data protocol stack. As shown in FIG. 5, a higher layer (OAM module in FIG. 5) of a MT (i.e., a first unit) of a network control repeater 50 (i.e., a first node) performs OAM configuration for the MT and the RU (i.e., a second unit) based on the OAM data.

[0057] In another example, the first unit establishes an OAM connection with an OAM server over Layer 2.

[0058] For example, the first node generates OAM data, packages it into a Layer 2 protocol data unit, and transfers it from the network device to the OAM server via the Layer 2 protocol. Downstream OAM data sent from the OAM server to the first node is also sent to the network device via the Layer 2 protocol, and the network device forwards it to the first node after receiving it. After receiving the downstream OAM data, the first node entrusts the OAM module with its processing.

[0059] In this example, the OAM data protocol stack of the first node may include an L1 layer, an L2 layer, and an OAM layer, and the OAM layer is located above the L2 layer. In this example, the protocol types of the L1 layer and the L2 layer are not limited.

[0060] 6 is yet another exemplary schematic diagram of an OAM data protocol stack, and as shown in FIG. 6, the protocols of Layer 2 and Layer 1 are not specifically limited. The OAM module of the MT (i.e., the first unit) of the network control repeater 60 (i.e., the first node) performs OAM configuration for the MT and / RU (i.e., the second unit) based on the OAM data.

[0061] In Figures 4 to 6, "OAM" refers to a functional module that achieves OAM configuration, and is not necessarily a single protocol layer; it can be an application program or a simple command interface.

[0062] The above embodiments are merely illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0063] The method according to the present embodiment can effectively aggregate the network in the network to which the first node is assigned, and can dynamically manage and control the second unit of the first node, thereby enhancing the network coverage and providing better services to users.

[0064] Example of the second aspect This embodiment provides a network integration method for nodes, and will be explained from the perspective of network equipment. The same content as in the first embodiment will not be explained again.

[0065] FIG. 7 is another schematic diagram of a node network integration method in an embodiment of the present application. As shown in FIG. 7, the method includes: 701: A network device responds to an access request of a first unit of a first node by allowing the first unit of the first node to access a network; 702: The network device receives capability information reported by the first unit of the first node, the capability information indicating that the first node includes a second unit; 703: The network device logs in and empowers the first node to a core network; The first unit is used to configure the second unit, the second unit is used to forward signals between the network equipment and the terminal equipment, and the second unit accesses the network in the first unit, reports capability information to the network equipment, and starts up after logging in and empowering to the core network through the network equipment.

[0066] It should be noted that the above-mentioned attached drawing 7 is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of each operation can be appropriately adjusted, and further, other operations can be added or certain operations can be deleted. Those skilled in the art are not limited to the description of the attached drawing 7, and can appropriately modify it according to the above content.

[0067] In a series of embodiments, the network device may further transmit air interface indication information to the first unit of the first node, so that the first unit of the first node selects and accesses a network device supporting the first node based on the air interface indication information of the candidate network devices.

[0068] In one set of embodiments, the network device may further receive a first message reported by a first unit of the first node, the first message including the capability information, the capability information including information for indicating the capabilities of the first node and / or the type of the first node.

[0069] In the above embodiment, the first message may be an RRC Setup Complete message.

[0070] The above embodiments are merely illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0071] The method according to the present embodiment can effectively aggregate the network in the network to which the first node is assigned, and can dynamically manage and control the second unit of the first node, thereby enhancing the network coverage and providing better services to users.

[0072] Third-party examples In the present embodiment, a communication control method is provided, and will be explained starting from the first node side.

[0073] FIG. 8 is a schematic diagram of a communication control method according to an embodiment of the present invention. As shown in FIG. 8, the method includes: 801: A first unit of a first node receives control information from a network device; 802: The first unit of the first node manages and configures the second unit of the first node according to the control information, and the second unit is used to transfer an analog upstream signal from a terminal device to a network device, or to transfer an analog downstream signal from a network device to a terminal device.

[0074] In the present embodiment, as described above, the first node includes a first unit and a second unit, the first unit is a unit for configuring the second unit in the first node, and the second unit is a unit for transmitting signals between the network device and the terminal device in the first node. The control method for the control information can dynamically manage and control the second unit in the first node, thereby realizing an increase in network coverage and providing better services to users.

[0075] In the present embodiment, the first unit and the second unit may be two collocated units in the first node as shown in Fig. 2, but the present invention is not limited thereto, and the second unit may be a single entity in the first node. For example, in the entire network, the first node acts as a special UE, accessing and managing RRC (Radio Resource Control) according to conventional UE behavior, and the second unit is not a collocated part but an entity within the UE, used to amplify and forward frequency signals.

[0076] In this embodiment, the user plane of the first node only relates to the second unit, and Figure 9 is a schematic diagram of the user plane protocol stack of the network control repeater 90 (i.e., the first node). As shown in Figure 9, the radio frequency module RF of the RU part (i.e., the second unit) functions as an amplifier to forward analog upstream signals from UE91 to gNB92, or forward analog downstream signals sent by gNB92 to UE91.

[0077] In this embodiment, the second unit itself only has RF functionality, does not have an upper layer protocol stack, and cannot directly interface with the network device, so the network device can only indirectly control the second unit through control over the first unit.

[0078] In one set of embodiments, the control information may be carried by dynamic signals.

[0079] In one example, the dynamic signal is a layer 2 signal.

[0080] In this example, the control plane protocol stack of the first unit (i.e., the control plane protocol stack between the first unit and the network device) may include a physical layer and a MAC layer. Figure 10 is an exemplary schematic diagram of the control plane protocol stack of the network control repeater (i.e., the first node).

[0081] As shown in Figure 10, the control plane protocol stack exists between the gNB 100 and the NCR-MT (i.e., the first unit) of the network control repeater 101. The control plane protocol stack manages and controls the MT via MAC layer / physical layer (PHY) protocols, and can use the NR Uu interface in existing technology, for example. The MT then manages and configures the RU (i.e., the second unit) internally according to the configuration or instructions of the gNB 100, so that the RU can perform highly efficient user plane amplification and forwarding operations and also perform network control relay functions.

[0082] In this example, the Layer 2 signaling can also use a MACCE (Control Unit) to carry the control message to dynamically control the first node, which can be a MAC PDU between MAC layers and carries only control information.

[0083] In another example, the dynamic signal is a layer 1 signal.

[0084] In this example, the control plane protocol stack of the first unit (i.e., the control plane protocol stack between the first unit and the network device) includes a physical layer.
