Description

[Technical field]

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

[0002] The coverage problem is a fundamental issue in the deployment of cellular networks. Mobile operators employ different types of nodes in their deployments to provide complete coverage. Although a regular full protocol stack cell deployment is certainly the best, it is not always feasible (e.g., no backhaul links) or economically feasible. Therefore, mobile operators are considering the use of new types of nodes to increase the flexibility of network deployment. For example, 3GPP R16 and R17 introduce a new type of node that does not require a wired backhaul, namely Access-back Integration (IAB). Another type of node is the radio frequency repeater (also called RF repeater). Radio frequency repeaters are usually non-generative and simply amplify and forward (Amplify & Forward: AF) all the signals they receive. Radio frequency repeaters are widely deployed in all 2G, 3G and 4G to complement the coverage provided by regular full protocol stack cells.

[0003] 3GPP R17 introduces radio frequency repeaters for New Radio (NR) to increase the coverage area of ​​NR cellular network deployment. Figure 1 is a schematic diagram of a simple radio frequency repeater. Radio frequency repeaters are usually full duplex and cannot distinguish uplink and downlink transmissions. The advantages of radio frequency repeaters are low cost, easy deployment, and no increase in delay. The disadvantage of radio frequency repeaters is that noise is amplified together, which may increase interference to the signal.

[0004] The above description of the background art is merely for the purpose of more clearly and completely explaining the configurations of the present invention and for the understanding of those skilled in the art, and should not be construed as meaning that these configurations are well known to those skilled in the art just because they are described in the background art of the present invention. Summary of the Invention [Problem to be solved by the invention]

[0005] According to the discovery of the inventors of the present invention, the radio frequency repeater of NR standardizes the needs of radio frequency and electromagnetic compatibility (EMC), and also needs to consider the frequency bands of FR1 (FDD (Frequency Division Duplex) and TDD (Time Division Duplex)) and FR2 (TDD). 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 the frequency band ranges of 5G NR, which correspond to the low frequency band range and the high frequency band range, respectively.

[0006] In order to optimize system performance, including possible interference mitigation and further coverage improvement, a network-controlled repeater (NC repeater, also called 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 corresponds to an extension of the conventional radio frequency repeater. However, the configurations and functions of how to configure the network-controlled repeater in various states of the network-controlled repeater, such as the initial state, the connection state, etc., are not 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 an apparatus for setting up a node, configured in a first node, the apparatus including: the first unit for setting up a second unit of the apparatus 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 for transmitting a message regarding the configuration of a second unit of the first node to a first unit via a signaling procedure between the first unit of the first node and the network device, the first unit of the first node configuring the second unit of the first node via the signaling procedure.

[0010] One of the advantageous effects of the embodiment of the present invention is as follows: According to the embodiment 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, so as to improve the network coverage and provide better services to users.

[0020] Additionally, communications between devices in a communication system may occur according to any stage of communication protocols, 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 communication protocols.

[0021] In the embodiment of the present invention, the term "network device" refers to a device in a communication system, for example, allowing a terminal device to access the communication system and providing a service to the terminal device. The network device 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), and 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 an apparatus that accesses a communication network and receives a network service via, for example, a network device. The terminal apparatus may be fixed or mobile, and may 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, and the like.

[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 equipment, 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, and the like.

[0026] FIG. 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's functions and is used to communicate with the gNB 21, and this part may be called MT (mobile termination) 22, but the present invention is not limited thereto and may have other names. The other part realizes radio frequency functions, i.e., the amplify and forward function of the repeater, and may be called RU (radio unit) 23, but the present invention is not limited thereto and may have other names as well as MT.

[0027] As shown in FIG. 2, the link between the gNB21 and the MT22 is a control link or control path, and also a fronthaul link. Through this control link, the gNB21 can configure the network-controlled repeater 20 with side control information, such as TDD configuration, on / off information, and beamforming information of the RU. This control link can be based on the existing Uu interface. The MT22 applies these configuration information to the RU (i.e., AF module) 23 through the internal operation of the network-controlled repeater 20. This side control means that the network device (gNB21) originally wants to control the RU23, but since there is no direct interface between the network device (gNB21) and the RU23, the network device (gNB21) controls the RU23 through a control interface with the MT22.

[0028] As shown in Figure 2, the access link from the gNB 21 to the normal UE 24 is referred to as the AF link, also referred to as the data path, since 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 the existence of the network controlled repeater 20. This data path (using the FR2 frequency band for example) carries analog uplink / downlink signals from the UE 24 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] As discovered by the inventors of the present invention, the main advantage of the network-controlled repeater is a simpler protocol stack and network integration than traditional relays, IAB-DU (integrated access and backhaul-distributed units) 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 unnecessary noise amplification and achieving highly spatially directional transmission and reception.

[0030] Also, the following possible technical directions are considered for the network-controlled repeater. The design contents of the side control information include basic design such as beamforming information configuration, timing, TDD configuration, on / off of transceivers, bandwidth information, power control, same-frequency related problems or radio frequency requirements, etc. Consider and confirm the signaling and configuration for carrying the side control information. In addition to the side control information, the management of the network-controlled repeater requires standardization, such as authentication / authorization and interference management.

[0031] However, as mentioned above, the configurations and functions of how to configure the network-controlled repeater in various states of the network-controlled repeater, such as the initial state, the connected state, etc., 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 improve 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 that realizes the above-mentioned MT function in this first node is referred to as a first unit, and a unit that realizes the above-mentioned RU function in this first node is referred to as a second unit.

[0034] <Example 1> An embodiment of the present invention provides a node setup method, which is described from the perspective of a first node, where setup includes configure, activate, report 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 network device, for example, by setting default parameters, reporting capabilities, starting or ending the process of operation, 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, as shown in Fig. 2, the first unit and the second unit may be two collocated units in the first node. However, the embodiment of the present invention is not limited thereto, for example, the second unit may be a separate entity in the first node. For example, in the whole network, the first node, as a special UE, 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 inside the UE to amplify and forward radio frequency signals.

[0039] In the embodiment of the present invention, the user plane of the first node only relates 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) serves 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, and 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, and 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 the protocols of RRC / PDCP / RLC / MAC / PHY layers from top to bottom, and the prior art Uu interface can be used between the gNB 51 and the MT. And the MT manages and configures the RU (i.e., the second unit) internally according to the configuration or instruction of the gNB 51. This enables the RU to realize efficient amplify-and-forward operation of the user plane and realize network-controlled relay functionality.

[0041] In some embodiments, the control plane protocol stack of the first unit further includes a NAS (Non-Access Stratum) protocol layer (not shown in FIG. 5), which is located above the RRC layer. The NAS layer terminates to an AMF (Access and Mobility management Function) 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 the embodiments of the present invention, with respect to the signaling procedure between the first unit and the network device, in some embodiments, the first unit of the first node may support a conventional UE RRC procedure and further extend it based on this, and the first unit may configure the second unit through 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 an 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 considered 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, for example, by adding a new IE to the above RRC establishment message, and the new IE is, for example, ncr-Config. However, the present invention is not limited thereto, and may, for example, multiplex an existing IE in the RRC establishment message, or indicate the associated configuration of the second unit in other manners.

[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; a 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, a period of the on / off mode, an on time within the period, etc. Here, the beamforming capability is target beam information, such as beam information from the TRP to the NCR link and / or beam information from the NCR to the UE link, etc. Here, the power and / or gain control information is used for efficient interference management, and includes, for example, gain control information per carrier frequency or BWP (bandwidth part). Here, the bandwidth information is, for example, pass band / carrier frequency / BWP bandwidth and center frequency point, 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 meaning of the layer 1 parameters and the parameter timeAlignmentTimerCommon is the same as that described above, and the description thereof is omitted here. In addition, 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 according to the received associated configuration of the second unit.

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

[0069] The above describes an example in which a first unit configures a second unit through an RRC procedure between 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 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-mentioned embodiments are merely illustrative of the present invention, and the present invention is not limited thereto, and appropriate modifications may be made based on the above-mentioned embodiments. For example, each of the above-mentioned embodiments may be used alone, or one or more of the above-mentioned 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 the capability information of the second unit to the network device. When the first unit receives the message from the network device to inquire about the capabilities of the second unit, the first unit edits the capability information of the second unit and transfers it to the network.

[0073] FIG. 6 is a schematic diagram of an example of an RRC procedure of capability reporting of a second unit. As shown in FIG. 6, when the network device needs (more) capability information of the radio range of the second unit of the first node, it may initiate a capability transfer procedure of the second unit, i.e., send an RRC message, for example, called RUCapabilityEnquiry message, to the first unit. When the first unit receives this message, it edits a response message, called RUCapabilityInformation message, according to the content of the message. The response message may include the radio capability parameters of the second unit, for example, 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 including an IE for inquiring about the capability of the second unit, sent by the network device, and transmits a fourth message including an IE for indicating the capability of the second unit to the network device. That is, the existing RRC procedure and message for transferring UE capability are reused. An IE specific to the second unit is added to the message. For example, an IE for inquiring about the capability of the second unit is added to the UECapabilityEnquiry message, for example, referred to as ru-Capability-Request. For example, an IE for reporting the capability of the second unit is added to the UECapabilityInformation message, for example, referred to as RU-Capability, which is used to transfer the radio access capability parameters of the second unit, such as physical layer and radio frequency parameters. The relevant contents of the above UECapabilityEnquiry message and UECapabilityInformation message may refer to the related art, and the 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) may include: 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 a related 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 reconfiguration with sync is met, it may start operating according to the configuration by the first unit (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 described, the contents of which are incorporated herein by reference, and the description thereof will be omitted here.

[0077] In the above embodiments, 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, when the first unit and the second unit are two collocated units, starting the operation means activating, reactivating, or enabling the second unit, or when 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) may include: When the first unit enters the RRC idle state, If the RRCReconfiguration message received by the first unit includes a related configuration of the second unit, or the related configuration of the second unit includes a bandwidth configuration; If the first unit performs a reconfiguration with sync, If the first unit performs the RRC connection re-establishment initialization, The first unit may stop operating if at least one of the cases where a suspend configuration is included in an RRC release message received by the first unit is met.

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

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

[0082] The above-mentioned embodiments are merely illustrative of the present invention, and the present invention is not limited thereto, and appropriate modifications may be made based on the above-mentioned embodiments. For example, each of the above-mentioned embodiments may be used alone, or one or more of the above-mentioned 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 described from the perspective of the network device. Descriptions similar to those of the first embodiment will be omitted.

[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. 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 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.
