[0032] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, but should not be construed as a limitation to the present disclosure.

[0033] First, the implementation environment of the embodiments of the present disclosure will be introduced below: Figure 1 An exemplary schematic diagram of a system architecture based on a network control repeater is shown. A network control repeater (NCR, Network controlled repeater) can improve system coverage in a low-cost manner, such as Figure 1As shown, the network control repeater consists of two parts. The mobile terminal (NCR-MT, Network controlled repeater Mobiletermination) part can be used to receive control commands sent by network devices (such as base stations, high-layer network devices). The control commands are used to control the behavior of the repeater (NCR-Fwd, Network controlled repeater-Forwarding), that is, the behavior on the backhaul link and the access link, such as the beam indication direction, the opening and closing of forwarding, etc. Among them, referring to Figure 1 , the backhaul link can be used for the repeater to communicate with network devices, and the access link can be used for the repeater to communicate with user equipment, so that the user equipment can communicate with network devices through this network control repeater. It can be understood that this network control repeater can also communicate with multiple user equipment.

[0034] Specifically, the above high-layer network devices may include a mobility management network element, a session management network element, a user plane network element, and a data network (DN). The user equipment can communicate with the DN through the base station and the user plane network element.

[0035] The above network elements can be either network elements in the 4G architecture or network elements in the 5G architecture.

[0036] The data network (DN), which provides data transmission services for users, can be a Protocol Data Unit (PDN) network, such as the Internet, IP Multi-media Service (IMS), etc.

[0037] The mobility management network element may include the access and mobility management function (AMF) in 5G. The mobility management network element is responsible for the access and mobility management of user equipment and / or network control repeaters in the mobile network. Among them, the AMF is responsible for the access and mobility management of user equipment and / or network control repeaters, NAS message routing, selection of the session management function entity (SMF), etc. The AMF can be used as an intermediate network element to transmit session management messages between user equipment and / or network control repeaters and the SMF.

[0038] The session management network element is responsible for forwarding path management, such as sending a packet forwarding policy to the user plane network element, instructing the user plane network element to process and forward packets according to the packet forwarding policy. The session management network element can be the SMF in 5G, responsible for session management, such as session creation / modification / deletion, user plane network element selection, and allocation and management of user plane tunnel information, etc.

[0039] The user plane network element can be the user plane function entity (UPF) in the 5G architecture. The UPF is responsible for packet processing and forwarding.

[0040] The system architecture provided by the embodiments of the present disclosure may further include a data management network element, which is used to process user equipment and / or network control repeater device identifiers, access authentication, registration, and mobility management, etc. In the 5G communication system, the data management network element can be the unified data management (UDM) network element.

[0041] The system architecture provided by the embodiments of the present disclosure may further include a policy control function entity (PCF) or a policy and charging control function entity (PCRF). Among them, the PCF or PCRF is responsible for policy control decision-making and flow-based charging control.

[0042] The system architecture provided by the embodiments of the present disclosure may further include a network storage network element, which is used to maintain real-time information of all network function services in the network. In the 5G communication system, the network storage network element can be the network repository function (NRF) network element. A lot of network element information can be stored in the network repository network element, such as the information of the SMF, the information of the UPF, the information of the AMF, etc. Network elements such as AMF, SMF, and UPF in the network may all be connected to the NRF. On the one hand, they can register their own network element information to the NRF, and on the other hand, other network elements can obtain the information of the network elements that have been registered in the NRF. Other network elements (such as the AMF) can obtain optional network elements by requesting from the NRF according to network element type, data network identifier, unknown area information, etc. If the domain name system (DNS) server is integrated in the NRF, then the corresponding selection function network element (such as the AMF) can request from the NRF to obtain other network elements to be selected (such as the SMF).

[0043] The base station in the above-mentioned network device can be a specific implementation form of an access network (AN), and can also be called an access node. If it is in the form of wireless access, it is called a radio access network (RAN), and can provide wireless access services for user equipment and / or network control repeaters. The access node can specifically be a base station in a global system for mobile communication (GSM) system or a code division multiple access (CDMA) system, or a base station (NodeB) in a wideband code division multiple access (WCDMA) system, or an evolutional node B (eNB or eNodeB) in an LTE system, or a base station device, small base station device, wireless access point (WiFi AP), worldwide interoperability for microwave access base station (WiMAX BS), etc. in a 5G network. The present disclosure does not limit this.

[0044] The above-mentioned user equipment (UE) can also be called a terminal, access terminal, user unit, user station, mobile station, mobile device, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device, etc. The user equipment can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing devices connected to a wireless modem, in-vehicle device, wearable device, Internet of Things terminal device, such as a fire detection sensor, smart water meter / electric meter, factory monitoring device, and so on.

[0045] The above functions can be either network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0046] Based on the above system architecture, the indication of beamforming information can indicate the beams on the backhaul link and / or the control link in a semi-static manner. Since both the control link and the backhaul link are the links between the NCR and the network device, when at least the mobile terminal and the repeater of the network control repeater operate in the same frequency band or adjacent frequency bands, it can be assumed that the large-scale channel characteristics of the control link and the backhaul link are the same. Therefore, the beam used on the control link can be assumed to be the beam of the backhaul link.

[0047] In the related art, for the beam configuration of the control link, it can be indicated for each signal / channel separately, or for multiple channels / signals. At this time, multiple channels can be indicated by the same beam. For downlink reception and uplink transmission, such as PUCCH, PUSCH, PDCCH, and PDSCH, a single beam is uniformly used. In this way, when configuring the control link beam, multiple TCI (Transmission Configuration Indicator) states may be configured for the control link of the mobile terminal to indicate multiple beams. In this case, how to enable the network control repeater to determine the optimal beam applied to its backhaul link more quickly and accurately is an urgent problem to be solved.

[0048] Specifically, in the related art, in the case of configuring multiple beams for the control link of the mobile terminal, the network control repeater needs to test each beam to determine the beam with the best backhaul link performance, resulting in low beam determination efficiency and unable to ensure the immediacy of communication.

[0049] To solve the problems existing in the related art, the embodiments of the present disclosure provide a beam indication method, device, and storage medium for the backhaul link.

[0050] Figure 2 It is a flowchart of a beam indication method for a backhaul link shown according to an exemplary embodiment, applied to a network control repeater, as Figure 2 shown, the method includes: S201. The network control repeater receives a signaling sent by the network device for configuring the beam of the backhaul link, and the signaling includes beam indication information.

[0051] Among them, the network device can be a base station or a high-layer network device. The high-layer network device can be, for example, a network device in the core network (such as an access and mobility management entity, etc.).

[0052] S202. The network control repeater determines the target beam used for the backhaul link from multiple beams configured by the network device for the control link of the network control repeater according to the beam indication information.

[0053] Among them, the target beam may be a beam with better transmission effect among multiple beams configured for the control link determined by the network device.

[0054] In one example, the beam indication information includes one or more of a beam identifier, a reference signal identifier, beam-related information, and a binding relationship between a backhaul link and a target physical channel in a network control repeater.

[0055] Among them, when the beam indication information includes multiple ones of a beam identifier, a reference signal identifier, beam-related information, and a binding relationship between a backhaul link and a target physical channel in a network control repeater, the network control repeater may determine the rate of the target beam according to different information, and select the information with the fastest determined rate from the beam indication information for determining the target beam used by the backhaul link.

[0056] Among them, there is a one-to-one correspondence between the beam identifier (beam ID) and the reference signal identifier (RS ID, Reference Signal ID) and multiple beams configured by the network device for the control link of the network control repeater. The target physical channel may be any channel in the control link for communication between the network device and the network control repeater, and the target physical channel may be the channel with the best detected performance by the network device.

[0057] In one example, the beam-related information includes one or more of transmission configuration indication information, spatial relation indication information, and quasi-co-location information configured by the network device for the control link.

[0058] Among them, the transmission configuration indication state (TCI-State) sent when configuring the beam for the control link of the network control repeater may include a transmission configuration indication state identifier (TCI-StateID) for uniquely identifying the transmission configuration indication state, and the transmission configuration indication information may be the transmission configuration indication state identifier (TCI-StateID) in the transmission configuration indication. Similarly, the spatial relation indication information may include a unique identifier corresponding to the spatial relation indication (SRI, spatial relation indicator), and the quasi-co-location information may include a unique identifier corresponding to the quasi-co-location (QCL, quasi-co-location).

[0059] Alternatively, the transmission configuration indication information may be the transmission configuration indication state, the spatial relation indication information may include the spatial relation indication, and the quasi-co-location information may include the quasi-co-location. The present disclosure does not limit this.

[0060] It should be noted that in the transmission configuration indication state (TCI-State), quasi-co-location (QCL) can be included. Among them, the quasi-co-location can indicate the corresponding spatial reception parameters. Under the assumption of beam correspondence, the spatial transmission parameters and spatial reception parameters of the user equipment or the network-controlled repeater are the same, and thus the beam can be determined based on this quasi-co-location. In addition, different quasi-co-location types (QCL types) have different channel characteristics, and two reference signals with a QCL relationship have the same channel characteristics.

[0061] In addition, the spatial relation indicator (SRI) can include the spatial relationship between the network-controlled repeater and the network device. Furthermore, the network-controlled repeater can determine the beam corresponding to this spatial relationship from multiple beams according to this spatial relationship.

[0062] By adopting the above solution, the network device can send any one of the transmission configuration indication information, spatial relation indication information, and quasi-co-location information corresponding to the target beam. The network-controlled repeater can then determine the target beam based on the corresponding beam indication information, without having to test each of the multiple beams configured for the control link one by one, effectively improving the beam determination efficiency of the backhaul link.

[0063] In some other examples, the signaling for configuring the beam of the backhaul link is the RRC signaling sent by the base station, or the signaling carried in the OAM (Operation Administration and Maintenance) message sent by the high-level network device.

[0064] Optionally, the RRC signaling is sent by the base station in a unicast or multicast manner.

[0065] It can be understood that there can be multiple network-controlled repeaters communicating with the base station. For the network-controlled repeaters accessing this base station, or the group of network-controlled repeaters, the base station can send RRC signaling specifically to indicate the beam used for the backhaul link of each network-controlled repeater or each group of network-controlled repeaters.

[0066] By adopting the above solution, the base station sends RRC signaling to the network-controlled repeater in a unicast or multicast manner to indicate the beam used for the backhaul link of the network-controlled repeater, and can make a targeted indication, which can effectively ensure the performance of the beam used for the backhaul link of each network-controlled repeater.

[0067] In an embodiment of the present disclosure, the network control repeater can quickly and accurately determine the beam used for the backhaul link between the repeater in the network control repeater and the network device from among multiple beams used for the control link of communication between the mobile terminal in the network control repeater and the network device by receiving the beam indication information in the signaling sent by the network device. The network control repeater can quickly determine the beam with better backhaul link performance without testing each of the multiple beams one by one, effectively improving the communication efficiency and performance.

[0068] Figure 3 is a flowchart of a method for indicating a beam of a backhaul link shown according to an exemplary embodiment, which is applied to a network control repeater, as Figure 3 shown, the method includes: S301. The network control repeater receives a signaling sent by the network device for configuring the beam of the backhaul link, and the signaling includes beam indication information; wherein, the beam indication information includes a beam identifier or a reference signal identifier.

[0069] S302. The network control repeater determines the target beam used for the backhaul link according to the reference signal identifier or the beam identifier.

[0070] It can be understood that after configuring multiple beams for the control link of the network control repeater, each beam or the reference signal corresponding to each beam among the multiple beams can be uniquely identified. Among them, there is a unique corresponding relationship between the reference signal identifier and the reference signal, and there is a unique corresponding relationship between the beam identifier and the beam.

[0071] Among them, the network device can be a base station or a high-level network device. The signaling can be an RRC signaling sent by the base station in a unicast or multicast manner, or a signaling carried in an OAM message sent by the high-level network device. The embodiments of the present disclosure do not limit this.

[0072] Adopting the above solution, the network control repeater can directly determine the target beam used for the backhaul link indicated by the network device by receiving the beam identifier or the reference signal identifier in the signaling sent by the network device. The network control repeater can quickly determine the beam with better performance for the backhaul link without testing each of the multiple beams one by one, effectively improving the communication efficiency and performance.

[0073] Figure 4 is a flowchart of a method for indicating a beam of a backhaul link shown according to an exemplary embodiment, which is applied to a network control repeater, as Figure 4 shown, the method includes: S401. The network control repeater receives a signaling for configuring a beam of a backhaul link sent by a network device, where the signaling includes beam indication information; wherein, the beam indication information includes beam-related information.

[0074] S402. The network control repeater determines a first reference signal identifier in the beam-related information according to the beam-related information.

[0075] S403. The network control repeater determines a target beam used for the backhaul link according to the first reference signal identifier.

[0076] Wherein, the beam-related information includes one or more of transmission configuration indication information, spatial relationship indication information, and quasi-co-location information configured by the network device for the control link.

[0077] With the above solution, the network control repeater receives the beam-related information of the signaling sent by the network device, and based on the transmission configuration indication information, spatial relationship indication information, and / or quasi-co-location information in the beam-related information, the network control repeater can determine the corresponding transmission configuration indication state, spatial relationship indication, and / or quasi-co-location, and then can determine the corresponding reference signal identifier based on the transmission configuration indication state, spatial relationship indication, and / or quasi-co-location, that is, can determine the target beam indicated by the network device for the backhaul link of the network control repeater based on the reference signal identifier, and can quickly determine a beam with better performance for the backhaul link without testing each of the multiple beams one by one, effectively improving the communication efficiency and performance.

[0078] Figure 5 It is a flowchart of a beam indication method for a backhaul link shown according to an exemplary embodiment, applied to a network control repeater, as Figure 5 shown, the method includes: S501. The network control repeater receives a signaling for configuring a beam of a backhaul link sent by a network device, where the signaling includes beam indication information; wherein, the beam indication information includes a beam identifier or a reference signal identifier, or beam-related information.

[0079] S502. The network control repeater determines a target beam used for the backhaul link from multiple beams configured by the network device for the control link of the network control repeater according to the beam indication information.

[0080] S503. The network control repeater determines an effective time of the target beam according to a preset duration in the communication protocol or a preset duration configured by the network device, and the preset duration is a duration relative to a specific moment.

[0081] Among them, the specific moment includes the end moment of the PDSCH where the network control repeater receives the beam indication information, and / or the moment of the last symbol of the uplink resource for the network control repeater to feedback the HARQ-ACK information for the PDSCH including the beam indication information.

[0082] Among them, the network device can be a base station or a high-layer network device. The signaling can be the RRC signaling sent by the base station in a unicast or multicast manner, or the signaling carried in the OAM message sent by the high-layer network device. The embodiments of the present disclosure do not make limitations thereto.

[0083] Exemplarily, the preset duration can be X unit durations. The unit duration can be the duration corresponding to one time slot, or the duration corresponding to one symbol or one subframe. The present disclosure does not make specific limitations thereto either.

[0084] For example, if the end moment of the PDSCH of the signaling where the network control repeater receives the beam indication information is the moment corresponding to slotn, and the unit duration is a time slot, where slot represents a time slot and n is the number of the time slot. If the effective time for the network control repeater to use the target beam in the backhaul link can be the moment corresponding to slot n+X, that is, the compression model is enabled at the moment corresponding to the time slot numbered n+X.

[0085] By adopting the above solution, by stipulating the preset duration in the communication protocol and determining the effective time of the target beam based on the specific moment corresponding to the beam knowledge information, it can enable the network device repeater to communicate reliably with the network device based on the backhaul link using the beam, and ensure the communication quality between the network device repeater and the network device.

[0086] Figure 6 is a flowchart of a beam indication method for a backhaul link shown according to an exemplary embodiment, applied to a network control repeater, as Figure 6 shown, the method includes: S601. The network control repeater receives the signaling sent by the network device for configuring the beam of the backhaul link, and the signaling includes beam indication information; among them, the beam indication information includes the binding relationship between the backhaul link and the target physical channel in the network control repeater.

[0087] S602. The network control repeater determines the first beam used by the target physical channel from the multiple beams configured by the network device for the control link of the network control repeater according to the binding relationship.

[0088] S603. The network control repeater uses the first beam as the target beam.

[0089] Among them, the network device can be a base station or a high-level network device. The signaling can be RRC signaling sent by the base station through unicast or multicast, or signaling carried in the OAM message sent by the high-level network device. The embodiments of the present disclosure do not limit this.

[0090] It can be understood that the target physical channel can be a channel of the control link for the mobile terminal of the network control repeater to communicate with the network device, and this channel can be a channel with better communication performance determined by the network device.

[0091] Specifically, in step S602 and step S603, the network control repeater can determine the reference signal identifier of the first beam used by the target physical channel according to the binding relationship and determine the target beam according to the reference signal identifier; or, it can determine the target beam according to the beam identifier of the beam used by the physical channel.

[0092] Adopting the above solution, the network control repeater receives the binding relationship between the backhaul link in the beam information sent by the network device and the target physical channel in the network control repeater, and determines the target beam used by the channel bound to the backhaul link according to the binding relationship. Without testing each of the multiple beams one by one, the backhaul link can quickly determine a beam with better performance, effectively improving the communication efficiency and performance.

[0093] Figure 7 is a flowchart of a method for beam indication of a backhaul link shown according to an exemplary embodiment, applied to a network control repeater, as Figure 7 shown, the method includes: S701. The network control repeater receives signaling sent by the network device for configuring the beam of the backhaul link, and the signaling includes beam indication information; among them, the beam indication information includes the binding relationship between the backhaul link and the target physical channel in the network control repeater.

[0094] S702. The network control repeater determines the first beam used by the target physical channel from multiple beams configured by the network device for the control link of the network control repeater according to the binding relationship.

[0095] S703. The network control repeater uses the first beam as the target beam.

[0096] S704. The network control repeater determines the first time when the target physical channel applies the first beam; S705. The network control repeater determines the first time as the effective time when the backhaul link uses the target beam.

[0097] Among them, the network device can be a base station or a high-layer network device. The signaling can be RRC signaling sent by the base station in a unicast or multicast manner, or signaling carried in an OAM message sent by the high-layer network device. The embodiments of the present disclosure do not limit this.

[0098] It can be understood that in the embodiments of the present disclosure, the first beam used by the target physical channel can be a beam that the target physical channel is about to use but has not started to use yet.

[0099] Adopting the above solution, when the beam indication information includes the binding relationship between the backhaul link and the target physical channel in the network control repeater, the effective time of the target beam determined by the backhaul link is the same as the time when the target physical channel bound to the backhaul link uses the corresponding first beam, which can effectively ensure the reliability of communication between the network control repeater and the network device through the backhaul link.

[0100] Figure 8 is a flowchart of a beam indication method for a backhaul link shown according to an exemplary embodiment, applied to a network control repeater, such as Figure 8 shown, the method includes: S801. The network control repeater receives signaling sent by the network device for configuring the beam of the backhaul link, and the signaling includes beam indication information.
