Description

[Technical Field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] The coverage issue is a fundamental problem in cellular network deployment. Mobile operators employ different types of nodes in their deployments to provide complete coverage. While a typical full-protocol stack cell deployment is certainly optimal, it is not always feasible (e.g., lacks a backhaul link) or economically feasible. Therefore, mobile operators are considering the use of new types of nodes to increase the flexibility of their network deployments. For example, 3GPP R16 and R17 introduced a new type of node, Access-back Integration (IAB), that does not require a wired backhaul. Another type of node is the radio frequency repeater (also called an RF repeater). Radio frequency repeaters are typically non-generative and simply amplify and forward (AF) all signals they receive. Radio frequency repeaters have been widely deployed in all 2G, 3G, and 4G to complement the coverage provided by typical full-protocol stack cells.

[0003] 3GPP R17 introduces radio frequency repeaters for New Radio (NR) to increase the coverage area of ​​NR cellular network deployments. Figure 1 is a schematic diagram of a simple radio frequency repeater. Radio frequency repeaters are typically full-duplex and cannot distinguish between uplink and downlink transmissions. The advantages of radio frequency repeaters are low cost, easy deployment, and no increased latency. The disadvantage of radio frequency repeaters is that noise is amplified together, potentially increasing interference with signals.

[0004] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] According to the discovery of the present inventors, NR radio frequency repeaters standardize the needs for radio frequency and electromagnetic compatibility (EMC) and must also consider the frequency bands FR1 (Frequency Division Duplex (FDD) and Time Division Duplex (TDD)) and FR2 (TDD). Radio frequency repeaters do not need to perform adaptive beamforming for UEs. They also do not consider various factors that can improve performance. FR1 (frequency range 1) and FR2 (frequency range 2) are 5G NR frequency band ranges, corresponding to the low and high frequency band ranges, respectively.

[0006] To optimize system performance, including possible interference mitigation and further coverage improvement, a network-controlled repeater (NC repeater, also called an intelligent repeater or smart repeater) capable of receiving and processing side control information from the network has been proposed and is considered to be an effective scheme for improving network topology. This network-controlled repeater is an extension of a conventional radio frequency repeater. However, the configuration and functions of how to set the network-controlled repeater in various states, such as the initial state and the connected state, have not been standardized.

[0007] In view of at least one of the above problems, embodiments of the present invention provide a method and apparatus for configuring a node. [Means for solving the problem]

[0008] In one aspect of an embodiment of the present invention, there is provided a node setup device configured in a first node, the device including: the first unit for setting up a second unit of the device via a signaling procedure between the first unit and a network device; and a second unit for forwarding signals between a terminal device and the network device.

[0009] Another aspect of an embodiment of the present invention provides an apparatus for setting up a node configured in a network device, the apparatus including: a transmitter that transmits a message regarding the configuration of a second unit of the first node to a first unit of the first node via a signaling procedure between the first unit and the network device, and the first unit of the first node configures the second unit of the first node via the signaling procedure.

[0010] One of the advantageous effects of the embodiments of the present invention is as follows: According to the embodiments of the present invention, in a network where a first node is deployed, a second unit can be effectively configured, and a network device can easily control the second unit, thereby improving network coverage and providing better services to users.

In the specification and drawings, specific embodiments of the present invention are disclosed in detail, and some of the embodiments in which the principles of the present invention can be adopted are shown. However, the present invention is not limited to the described embodiments. The present invention includes all modifications, variations, and equivalents within the scope of the appended claims. Below, various embodiments of the present invention will be described with reference to the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0019] In embodiments of the present invention, the terms "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as, for example, Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0020] Additionally, communications between devices in a communications system may occur according to any stage of communications protocol, including, but not limited to, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, and future 5G, New Radio (NR), and / or other currently known or future developed communications protocols.

[0021] In an embodiment of the present invention, the term "network device" refers to a device in a communication system that allows a terminal device to access the communication system and provides a service to the terminal device, and may include, but is not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobility management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0022] Here, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), etc., as well as a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). Also, the term "base station" may include some or all of these functions, and each base station may provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0023] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives network services via, for example, a network device. The terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, etc.

[0024] Here, the terminal device may include, but is not limited to, a cellular phone, a personal digital assistant (PDA), a wireless modulation / demodulation device, a wireless communication device, a handheld device, a machine-type communication device, a laptop computer, a cordless phone, a smartphone, a smart watch, a digital camera, etc.

[0025] Also, for example, in a scenario such as the Internet of Things (IoT), the user equipment may be a monitoring or measuring device or apparatus, and may include, but is 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.

[0026] 2 is a schematic diagram of an example of the configuration of a network-controlled repeater. As shown in FIG. 2, the network-controlled repeater 20 may be divided into two parts. One part realizes part of the UE functions and is used to communicate with the gNB 21. This part may be called an MT (mobile termination) 22, but the present invention is not limited thereto and may have another name. The other part realizes a radio frequency function, i.e., the repeater's amplify-and-forward function, and may be called an RU (radio unit) 23, but the present invention is not limited thereto and may have another name, similar to the MT.

[0027] 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-controlled repeater 20 with side control information such as TDD configuration, on / off 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-controlled repeater 20. This side control refers to the network device (gNB 21) wanting to control the RU 23, but because there is no direct interface between the network device (gNB 21) and the RU 23, the network device (gNB 21) controls the RU 23 via a control interface with the MT 22.

[0028] As shown in Figure 2, the access link from the gNB 21 to a typical UE 24 is referred to as the AF link, also referred to as the data path, because the signal is amplified and forwarded by the network-controlled repeater 20. This network-controlled repeater 20 is transparent to the UE 24, and the UE 24 may not be aware of its existence. This data path (using, for example, the FR2 frequency band) carries analog uplink / downlink signals from or to the UE 24. This data path is essentially a pass-through for analog signals. The data path is entirely controlled by the gNB 21 (or distributed unit (DU)) via a control path.

[0029] The inventors of the present invention discovered that the main advantages of the network-controlled repeater are a simpler protocol stack and network integration than conventional relays, integrated access and backhaul-distributed units (IAB-DUs), and gNBs. Side control by the gNB enables efficient AF operation, for example, by dynamically changing the TX / RX (transmit / receive state) of the repeater, reducing unwanted noise amplification and achieving highly spatially directional transmission and reception.

[0030] The following technical directions are possible for network-controlled repeaters: The design of side control information includes basic design such as beamforming information configuration, timing, TDD configuration, transceiver on / off, bandwidth information, power control, same-frequency related issues or radio frequency requirements, etc. The signaling and configuration for carrying side control information will be considered and confirmed. In addition to side control information, management of network-controlled repeaters requires standardization of, for example, authentication / authorization and interference management.

[0031] However, as mentioned above, the configurations and functions of how to set the network-controlled repeater in various states of the network-controlled repeater, such as the initial state and the connected state, are not standardized.

[0032] Various embodiments of the present invention will now be described with reference to the drawings, which are merely illustrative and not limiting of the present invention.

[0033] In the embodiment of the present invention, for convenience of explanation, a node configured in a network to improve network coverage or user performance is referred to as a first node. This node may be the above-mentioned network-controlled repeater 20, a smart repeater (SR), a reconfigurable intelligent surface (RIS), etc., but the present invention is not limited to these names. Also, for convenience of explanation, a unit in this first node that realizes the above-mentioned MT function is referred to as a first unit, and a unit in this first node that realizes the above-mentioned RU function is referred to as a second unit.

[0034] Example 1 An embodiment of the present invention provides a node setup method, which is explained from the perspective of a first node, where setup includes configuring, activating, reporting capabilities, etc.

[0035] 3 is a schematic diagram of an example of a node configuration method according to an embodiment of the present invention. As shown in FIG. 3, the method includes the following steps:

[0036] Step 301: A first unit of a first node configures a second unit of the first node through a signaling procedure between the first unit and a network device, and the second unit of the first node is used to transfer signals between a terminal device and the network device.

[0037] In an embodiment of the present invention, as described above, the first node includes a first unit and a second unit, and the first unit configures the second unit through a signaling procedure between the first unit and the network device, for example, by setting default parameters, reporting capabilities, starting or ending operation processes, etc., the network device can easily control the second unit, thereby improving network coverage and providing better services to users.

[0038] In an embodiment of the present invention, the first unit and the second unit may be two collocated units in the first node, as shown in Fig. 2. However, the embodiment of the present invention is not limited thereto, and the second unit may be a separate entity in the first node. For example, in the overall network, the first node acts as a special UE and performs access and RRC (Radio Resource Control) connection management according to the operation of a conventional UE, while the second unit is not a collocated part and functions as an entity within the UE for amplifying and forwarding radio frequency signals.

[0039] In an embodiment of the present invention, the user plane of the first node relates only to the second unit. Figure 4 is a schematic diagram of an example of a user plane protocol stack of the network controlled repeater 40. As shown in Figure 4, the radio frequency module RF of the RU part (i.e., the second unit) functions as an amplifier to forward analog uplink signals from the UE 41 to the gNB 42, or forward analog downlink signals from the gNB 42 to the UE 41.

[0040] In an embodiment of the present invention, a control plane protocol stack exists between the network device and the first unit. The control plane protocol stack is also referred to as the control plane protocol stack of the first unit or the control plane protocol stack between the first unit and the network device. The second unit does not have a control plane protocol stack. In one embodiment, the control plane protocol stack between the first unit and the network device reuses the control plane protocol stack between the current network device and the UE, including a physical layer, a medium access control (MAC) layer, a radio link control (RLC) layer, a packet data aggregation protocol (PDCP) layer, and an RRC layer. FIG. 5 is a schematic diagram of an example of a control plane protocol stack of the network-controlled repeater 50. As shown in FIG. 5, the MT (i.e., the first unit) is managed and controlled by protocols of the RRC / PDCP / RLC / MAC / PHY layers from top to bottom, and a conventional Uu interface can be used between the gNB 51 and the MT. The MT then manages and configures the RU (i.e., the second unit) internally according to the configuration or instruction of the gNB 51. This allows the RU to realize efficient amplify-and-forward operation of the user plane and realize network-controlled relay functions.

[0041] In some embodiments, the control plane protocol stack of the first unit further includes a Non-Access Stratum (NAS) protocol layer (not shown in FIG. 5), which is located above the RRC layer. The NAS layer terminates to an Access and Mobility management Function (AMF) of the core network via the gNB 51 and provides functions such as authentication, mobility management, or security control of the first node via the core network.

[0042] In some embodiments of the present invention, with respect to the signaling procedure between the first unit and the network device, the first unit of the first node may support a conventional UE RRC procedure and may further extend it based on this, and the first unit may configure the second unit via the RRC procedure between the first unit and the network device.

[0043] In one example, the RRC connection establishment procedure of the second unit may be extended, that is, when the first unit performs RRC establishment initialization, it may perform at least one of the following steps:

[0044] The first unit applies default layer 1 parameter values ​​for the second unit other than the parameter values ​​provided by SIB1.

[0045] The first unit applies the parameter timeAlignmentTimerCommon contained in SIB1 for the second unit.

[0046] When the first unit receives the RRC Setup message, it performs a configuration procedure for the second unit according to the associated configuration of the received second unit.

[0047] In this example, the layer 1 parameters may include the frequency point, bandwidth, on / off mode, antenna beam configuration, transmit power, reference signal configuration, etc. of the second unit.

[0048] In this example, the parameter timeAlignmentTimerCommon is a cell-level timer for controlling the time taken into account for uplink time alignment of the terminal device, the details of which may be referred to in the related art, and the description thereof will be omitted here.

[0049] In this example, the associated configuration of the second unit may be indicated by adding a new IE to the RRC establishment message, for example, ncr-Config. However, the present invention is not limited thereto. For example, the associated configuration of the second unit may be indicated by multiplexing an existing IE in the RRC establishment message, or by other methods.

[0050] In this example, the associated configuration of the second unit includes semi-static parameters configured for the second unit and may include at least one of the following:

[0051] On / off mode, timing information for aligning transmission and / or reception boundaries; Beamforming capabilities, power and / or gain control information; Bandwidth information, a reference signal configuration for the second unit; the reference signal transmit power for the second unit, and The layer 2 and / or layer 3 configuration of the first node.

[0052] Here, the on / off mode is used for efficient interference management and energy saving, and includes, for example, an on / off mode cycle, an on time within the cycle, etc. Here, the beamforming capability is target beam information, for example, beam information for a link from the TRP to the NCR and / or beam information for a link from the NCR to the UE, etc. Here, the power and / or gain control information is used for efficient interference management, and includes, for example, gain control information for each carrier frequency or BWP (bandwidth part). Here, the bandwidth information is, for example, the bandwidth and center frequency point of the pass band / carrier frequency / BWP, etc. Here, the Layer 2 / Layer 3 configuration of the first node is, for example, the identifier, IP address, identifier and permission related information of the first node or first unit, etc.

[0053] In another example, the RRC connection re-establishment procedure of the first unit may be extended, i.e., after cell selection and when the T311 timer is running, the first unit performs at least one of the following steps:

[0054] The first unit applies default Layer 1 parameter values ​​for the second unit other than the parameter values ​​provided by SIB1.

[0055] The first unit applies the parameter timeAlignmentTimerCommon contained in SIB1 for the second unit.

[0056] In this example, the meanings of the Layer 1 parameters and the parameter timeAlignmentTimerCommon are the same as those described above, and the description thereof is omitted here. Also, the specific definition and operation of the T311 timer may refer to TS38.331.

[0057] In another example, the RRC reconfiguration procedure of the first unit may be extended, that is, when the first unit receives an RRC reconfiguration message, it performs the following steps:

[0058] Based on the received associated configuration of the second unit, a configuration procedure of the second unit is performed.

[0059] In this example, the meaning of the related configuration of the second unit is the same as that described above, and the description thereof will be omitted here.

[0060] In another example, the RRC connection resume procedure of the first unit may be extended.

[0061] For example, when the first unit performs RRC connection recovery initialization, it performs at least one of the following steps:

[0062] The first unit applies default Layer 1 parameter values ​​for the second unit other than the parameter values ​​provided by SIB1.

[0063] The first unit applies the parameter timeAlignmentTimerCommon contained in SIB1 for the second unit.

[0064] In this example, the meaning of the layer 1 parameters and the parameter timeAlignmentTimerCommon is the same as that described above, and the description thereof will be omitted here.

[0065] Also, for example, when the first unit receives an RRC recovery (RRCResume) message, it performs at least one of the following steps:

[0066] If the related configuration of the second unit is stored, restore the related configuration of the second unit from the UE Inactive AS context.

[0067] If the RRC recovery message includes the associated configuration of the second unit, perform a configuration procedure of the second unit based on the received associated configuration of the second unit.

[0068] In this example, the related configuration of the second unit is similar to that described above, and the description thereof will be omitted here.

[0069] The above describes an example in which a first unit configures a second unit through an RRC procedure between the first unit and a network device, but the present invention is not limited to this, and the first unit may configure the second unit through other signaling procedures between the first unit and the network device, the principles and embodiments of which are the same as those of the above examples, and the description thereof will be omitted here.

[0070] The above-described embodiments are merely illustrative of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above-described embodiments. For example, each of the above-described embodiments may be used alone, or one or more of the above-described embodiments may be used in combination.

[0071] In some embodiments of the present invention, the first unit may report the capabilities of the second unit to the network device.

[0072] In some embodiments, a new RRC procedure may be added to report the capabilities of the second unit, e.g., referred to as a second unit capability transfer procedure. For example, the first unit receives a message (referred to as a first message) sent from a network device to inquire about the capabilities of the second unit, and transmits a message (referred to as a second message) including capability information of the second unit to the network device. When the first unit receives the message to inquire about the capabilities of the second unit from the network device, the first unit compiles the capability information of the second unit and transfers it to the network.

[0073] 6 is a schematic diagram of an example of an RRC procedure for reporting the capabilities of a second unit. As shown in FIG. 6, when a network device needs (more) wireless coverage capability information of a second unit of a first node, it may initiate a capability transfer procedure of the second unit, i.e., send an RRC message, for example, referred to as an RUCapabilityEnquiry message, to the first unit. Upon receiving this message, the first unit compiles a response message, for example, referred to as an RUCapabilityInformation message, according to the message content. The response message may include wireless capability parameters of the second unit, such as supported passband width or band combination information, TDD or FDD capability information, multi-antenna MIMO capability information, etc.

[0074] In another embodiment, the capability of the second unit may be reported by extending the existing RRC capability transfer procedure. For example, the first unit receives a third message sent by the network device, the third message including an IE for inquiring about the capability of the second unit, and then transmits a fourth message to the network device including an IE for indicating the capability of the second unit. That is, the existing RRC procedures and messages for transferring UE capabilities are reused. An IE specific to the second unit may be added to the message. For example, an IE for inquiring about the capability of the second unit may be added to the UECapabilityEnquiry message, e.g., referred to as ru-Capability-Request. For example, an IE for reporting the capability of the second unit may be added to the UECapabilityInformation message, e.g., referred to as RU-Capability, which is used to transfer radio access capability parameters of the second unit, such as physical layer and radio frequency parameters. The relevant content of the above UECapabilityEnquiry message and UECapabilityInformation message may refer to the related art, and a description thereof will be omitted here.

[0075] In some embodiments of the present invention, the second unit of the first node (the amplifier portion of the first node) comprises: If the first unit receives an RRC Setup message and the second unit is configured: If the first unit's access layer security is activated, If the first unit receives an RRC Resume message: When a first unit restores the associated configuration of a second unit, When the first unit enters the RRC connected state, If the RRCReconfiguration message received by the first unit includes the associated configuration of the second unit, if the associated configuration of the second unit includes a bandwidth configuration; and If at least one of the cases where the first unit has performed a synchronous reconfiguration (reconfiguration with sync) is met, it may start operating according to the configuration by the first unit (the associated configuration of the second unit above).

[0076] In the above embodiment, the meaning of the related configuration of the second unit has already been explained, the contents of which are incorporated herein by reference, and the explanation thereof will be omitted here.

[0077] In the above embodiment, if the RRC Reconfiguration message includes the related configuration of the second unit, or the related configuration of the second unit includes a bandwidth configuration, or the first unit performs reconfiguration with sync, the second unit stops operating and then resumes operating according to the related configuration of the second unit in the RRC Reconfiguration message, i.e., stops operating and then resumes operating, which is also referred to as re-initiating or reactivating the operation.

[0078] In the above embodiment, if the first unit and the second unit are two collocated units, starting the operation means activating, reactivating, or enabling the second unit, or if the second unit is a separate entity in the first node, starting the operation means starting, creating, or activating the second unit entity.

[0079] In some embodiments of the present invention, the second unit of the first node (the amplifier portion of the first node) comprises: When the first unit enters the RRC idle state, If the RRCReconfiguration message received by the first unit includes the associated configuration of the second unit, or the associated configuration of the second unit includes a bandwidth configuration, If the first unit performs a reconfiguration with sync, If the first unit performs RRC connection re-establishment initialization, The first unit may stop operating if at least one of the following cases is met: the RRC release (RRCRelease) message received by the first unit includes a suspend configuration (suspendConfig).

[0080] In the above embodiment, the meaning of the related configuration of the second unit has already been explained, the contents of which are incorporated herein by reference, and the explanation thereof will be omitted here.

[0081] In the above embodiment, if the first unit and the second unit are two co-located units in the first node, stopping operation means deactivating or disabling the second unit, or if the second unit is a separate entity in the first node, stopping operation means releasing or deactivating the second unit entity.

[0082] The above-described embodiments are merely illustrative of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above-described embodiments. For example, each of the above-described embodiments may be used alone, or one or more of the above-described embodiments may be used in combination.

[0083] According to the method of the embodiment of the present invention, in a network in which a first node is deployed, a second unit can be effectively configured, and a network device can easily control the second unit, thereby improving network coverage and providing better services to users.

[0084] <Example 2> The embodiment of the present invention provides a node setup method, and will be explained from the network device side. The same content as in the first embodiment will not be explained again.

[0085] 7 is a schematic diagram of another example of a node configuration method according to an embodiment of the present invention. As shown in FIG. 7, the method includes the following steps:

[0086] Step 701: A network device sends a message regarding the configuration of a second unit of a first node to a first unit of a first node through a signaling procedure between the first unit and the network device, and the first unit of the first node configures the second unit of the first node through the signaling procedure (i.e., based on the message).

[0087] In some embodiments, the network device transmits a message regarding the configuration of the second unit of the first node to the first unit via a radio resource control (RRC) procedure between the first unit of the first node and the network device, such that the first unit of the first node configures the second unit of the first node via the RRC procedure.
