[0047] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0048] The following first introduces the implementation environment of the embodiment of the present disclosure:

[0049] Figure 1The schematic diagram of a system architecture based on a network controlled repeater is shown as an example. The network controlled repeater (NCR) can improve the system coverage in a low-cost manner, such as Figure 1 As shown, the network controlled 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 equipment (such as base stations, high-level network equipment). The control commands are used to control the behavior of the forwarder (NCR-Fwd, Network controlled repeater-Forwarding), that is, the behavior on the backhaul link (backhaul link) and the access link (control link), such as beam indication direction, forwarding on and off, etc. Figure 1 The backhaul link can be used for the repeater to communicate with the network device, and the access link can be used for the repeater to communicate with the user device, thereby enabling the user device to communicate with the network device through the network control repeater. It can be understood that the network control repeater can also communicate with multiple user devices.

[0050] Specifically, the above-mentioned high-level network equipment 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 may communicate with the DN through the base station and the user plane network element.

[0051] The above network elements can be network elements in the 4G architecture or network elements in the 5G architecture.

[0052] The data network (DN) provides data transmission services for users and can be a protocol data unit (PDN) network, such as the Internet, IP Multimedia Service (IMS), etc.

[0053] 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 relays in the mobile network. Among them, AMF is responsible for the access and mobility management of user equipment and / or network control relays, NAS message routing, session management function (SMF) selection, etc. AMF can be used as an intermediate network element to transmit session management messages between user equipment and / or network control relays and SMF.

[0054] The session management network element is responsible for forwarding path management, such as sending message forwarding policies to user-plane network elements, instructing user-plane network elements to process and forward messages according to the message forwarding policies. The session management network element can be the SMF in 5G, which is responsible for session management, such as session creation / modification / deletion, user-plane network element selection, and allocation and management of user-plane tunnel information.

[0055] The user plane network element can be a user plane function entity (UPF) in the 5G architecture. UPF is responsible for message processing and forwarding.

[0056] The system architecture provided by the embodiment of the present disclosure may also include a data management network element for processing user equipment and / or network control repeater equipment identification, access authentication, registration and mobility management, etc. In a 5G communication system, the data management network element may be a unified data management (UDM) network element.

[0057] The system architecture provided by the embodiment of the present disclosure may also include a policy control function (PCF) or a policy and charging control function (PCRF), wherein the PCF or PCRF is responsible for policy control decision-making and flow-based charging control.

[0058] The system architecture provided by the embodiment of the present disclosure may also include a network storage network element for maintaining real-time information of all network function services in the network. In the 5G communication system, the network storage network element may be a network repository function (NRF) network element. A lot of network element information may be stored in the network repository network element, such as SMF information, UPF information, AMF information, etc. Network elements such as AMF, SMF, and UPF in the network may be connected to NRF. On the one hand, their own network element information may be registered to NRF, and on the other hand, other network elements may obtain information about registered network elements from NRF. Other network elements (such as AMF) can obtain optional network elements by requesting NRF based on network element type, data network identifier, unknown area information, etc. If the domain name system (DNS) server is integrated in NRF, then the corresponding selection function network element (such as AMF) can request NRF to obtain other network elements to be selected (such as SMF).

[0059] The base station in the above network equipment can be used as a specific implementation form of the access network (AN), and can also be called an access node. If it is a form of wireless access, it is called a radio access network (RAN), which can provide wireless access services for user equipment and / or network control repeaters. The access node can 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 evolutionary base station (eNB or eNodeB) in an LTE system, or a base station device, a small base station device, a wireless access node (WiFiAP), a wireless interoperability microwave access base station (WiMAX BS) in a 5G network, etc., and the present disclosure does not limit this.

[0060] The above-mentioned user equipment (UE) may also be referred to as a terminal, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or a user device, etc. The user equipment may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, an Internet of Things terminal device, such as a fire detection sensor, a smart water meter / electricity meter, a factory monitoring device, etc.

[0061] The above functions can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0062] Based on the above system architecture, the indication of beamforming information can indicate the beam on the backhaul link and / or control link in a semi-static manner. Since the control link and the backhaul link are both links between the NCR and the network device, at least when the mobile terminal and the repeater of the network control repeater operate in the same frequency band or a similar frequency band, it can be assumed that the large-scale channel characteristics of the control link and the backhaul link are the same, so the beam used on the control link can be assumed to be the beam of the backhaul link.

[0063] In the related art, the beam configuration of the control link can be indicated for each signal / channel separately, or for multiple channels / signals. In this case, multiple channels can be indicated by the same beam, and downlink reception and uplink transmission such as PUCCH, PUSCH, PDCCH, and PDSCH all use one beam. 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 more quickly and accurately enable the network control repeater to determine the optimal beam for its backhaul link application is an urgent problem to be solved.

[0064] Specifically, in the related art, when multiple beams are configured for the control link of a mobile terminal, the network control repeater needs to test each beam to determine the beam with the best backhaul link performance, resulting in low efficiency in beam determination and failure to guarantee the immediacy of communication.

[0065] In order 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 a backhaul link.

[0066] Figure 2 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 2 As shown, the method includes:

[0067] S201. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information.

[0068] The network device may be a base station or a high-level network device. The high-level network device may be, for example, a network device in a core network (eg, an access and mobility management entity, etc.).

[0069] S202: The network control repeater determines, according to the beam indication information, a target beam used by the backhaul link from a plurality of beams configured by the network device for the control link of the network control repeater.

[0070] The target beam may be a beam with better transmission effect among multiple beams configured for the control link determined by the network device.

[0071] 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-controlled repeater.

[0072] Among them, when the beam indication information includes multiple of the beam identifier, the reference signal identifier, the beam-related information, and the binding relationship between the backhaul link and the target physical channel in the network control repeater, the network control repeater can determine the rate of the target beam based on different information, and select the information with the fastest rate from the beam indication information to determine the target beam used for the backhaul link.

[0073] Among them, the beam ID and the reference signal ID (RS ID) have a one-to-one correspondence with multiple beams configured by the network device for the control link of the network control repeater. The target physical channel can be any channel in the control link for communication between the network device and the network control repeater, and the target physical channel can be the channel with the best performance detected by the network device.

[0074] In one example, 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 a control link.

[0075] Among them, the transmission configuration indication state (TCI-State) sent when the network controls the beam of the control link configuration of the 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 relationship indication information may include a unique identifier corresponding to the spatial relationship 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).

[0076] Alternatively, the transmission configuration indication information may be a transmission configuration indication state, the spatial relationship indication information may include a spatial relationship indication, and the quasi-co-location information may include a quasi-co-location, which is not limited in the present disclosure.

[0077] It is worth noting that the transmission configuration indication state (TCI-State) may include quasi-co-address (QCL), where the quasi-co-address may 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 network control repeater are the same, and the beam can be determined based on the quasi-co-address. In addition, different quasi-co-address types (QCL types) contain different channel characteristics, and two reference signals with a QCL relationship have the same channel characteristics.

[0078] In addition, the spatial relation indicator (SRI) may include the spatial relation between the network control repeater and the network device, and the network control repeater may determine a beam corresponding to the spatial relation from a plurality of beams according to the spatial relation.

[0079] By adopting the above scheme, the network equipment can send any one of the transmission configuration indication information, spatial relationship indication information and quasi-co-address information corresponding to the target beam, and the network control repeater can determine the target beam based on the corresponding beam indication information. There is no need to test multiple beams configured for the control link one by one, which effectively improves the beam determination efficiency of the backhaul link.

[0080] In some other examples, the signaling used to configure the beam of the backhaul link is RRC signaling sent by the base station, or signaling carried by an OAM (Operation Administration and Maintenance) message sent by a high-level network device.

[0081] Optionally, the RRC signaling is sent by the base station in a unicast or multicast manner.

[0082] It can be understood that there can be multiple network-controlled repeaters communicating with the base station. For the network-controlled repeaters or network-controlled repeater groups connected to the base station, the base station can send RRC signaling specifically to indicate the beam used for the backhaul link of each network-controlled repeater or each network-controlled repeater group.

[0083] By adopting the above scheme, the base station sends RRC signaling to the network controlled repeater via unicast or multicast to indicate the beam used by the network controlled repeater backhaul link. The indication can be made in a targeted manner, which can effectively ensure the performance of the beam used by each network controlled repeater backhaul link.

[0084] In the disclosed embodiment, the network control repeater receives beam indication information in the signaling sent by the network device, and based on the beam indication information, can quickly and accurately determine the beam used for the return link between the repeater in the network control repeater and the network device from the multiple beams used for the control link between the mobile terminal in the network control repeater and the network device. The network control repeater does not need to test the multiple beams one by one and can quickly determine the beam with better performance in the return link, thereby effectively improving the efficiency and performance of communication.

[0085] Figure 3 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 3 As shown, the method includes:

[0086] S301. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information; wherein the beam indication information includes a beam identifier or a reference signal identifier.

[0087] S302: The network controls the repeater to determine a target beam used by the backhaul link according to a reference signal identifier or a beam identifier.

[0088] It can be understood that after configuring multiple beams, the control link of the network control repeater can uniquely identify each beam in the multiple beams or the reference signal corresponding to each beam, wherein 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.

[0089] The network device may be a base station or a high-level network device, and the signaling may be RRC signaling sent by the base station in a unicast or multicast manner, or may be signaling carried in an OAM message sent by a high-level network device, which is not limited in the embodiments of the present disclosure.

[0090] By adopting the above scheme, the network control repeater can directly determine the target beam used by the backhaul link indicated by the network device by receiving the beam identifier or reference signal identifier in the signaling sent by the network device. The network control repeater does not need to test the multiple beams one by one, and the backhaul link can quickly determine the beam with better performance, thereby effectively improving the efficiency and performance of communication.

[0091] Figure 4 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 4 As shown, the method includes:

[0092] S401. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information; wherein the beam indication information includes beam-related information.

[0093] S402: The network controls the repeater to determine a first reference signal identifier in the beam-related information according to the beam-related information.

[0094] S403: The network controls the repeater to determine a target beam used by the backhaul link according to the first reference signal identifier.

[0095] 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.

[0096] By adopting the above scheme, 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-address 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-address, and then can determine the corresponding reference signal identifier based on the transmission configuration indication state, spatial relationship indication and / or quasi-co-address, that is, it 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 the backhaul link can quickly determine the beam with better performance without testing the multiple beams one by one, thereby effectively improving the efficiency and performance of communication.

[0097] Figure 5 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 5 As shown, the method includes:

[0098] S501. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, 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.

[0099] S502: The network control repeater determines, according to the beam indication information, a target beam used by the backhaul link from multiple beams configured by the network device for the control link of the network control repeater.

[0100] S503. The network control repeater determines the effective time of the target beam according to the preset time in the communication protocol or the preset time configured by the network device, where the preset time is the time relative to a specific moment.

[0101] The specific moment includes the end moment when the network controls the relay to receive the PDSCH containing the beam indication information, and / or the moment when the network controls the relay to feed back the last symbol of the uplink resource of the HARQ-ACK information for the PDSCH including the beam indication information.

[0102] The network device may be a base station or a high-level network device, and the signaling may be RRC signaling sent by the base station in a unicast or multicast manner, or may be signaling carried in an OAM message sent by a high-level network device, which is not limited in the embodiments of the present disclosure.

[0103] For example, the preset duration may be X unit durations, and the unit duration may be a duration corresponding to a time slot, a duration corresponding to a symbol, or a duration corresponding to a subframe, which is not specifically limited in the present disclosure.

[0104] For example, if the end time of the PDSCH containing the signaling containing the beam indication information received by the network-controlled repeater is the time corresponding to slotn, the unit time length is the time slot, where slot represents the time slot and n is the number of the time slot. If the network-controlled repeater backhaul link uses the target beam, the effective time can be the time corresponding to slot n+X, that is, the compression model is enabled at the time corresponding to the time slot numbered n+X.

[0105] By adopting the above scheme, by stipulating the preset duration in the communication protocol and determining the effective time of the target beam based on the specific time corresponding to the beam knowledge information, the network device repeater can communicate reliably with the network device based on the return link using the beam, thereby ensuring the communication quality between the network device repeater and the network device.

[0106] Figure 6 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 6 As shown, the method includes:

[0107] S601. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information; wherein the beam indication information includes a binding relationship between the backhaul link and a target physical channel in the network control repeater.

[0108] S602: The network control repeater determines, according to the binding relationship, a first beam used by a target physical channel from a plurality of beams configured by the network device for a control link of the network control repeater.

[0109] S603: The network controls the repeater to use the first beam as the target beam.

[0110] The network device may be a base station or a high-level network device, and the signaling may be RRC signaling sent by the base station in a unicast or multicast manner, or may be signaling carried in an OAM message sent by a high-level network device, which is not limited in the embodiments of the present disclosure.

[0111] It can be understood that the target physical channel may be a channel of a control link for communication between a mobile terminal of a network control repeater and a network device, and the channel may be a channel with better communication performance determined by the network device.

[0112] 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 based on the binding relationship and determine the target beam based on the reference signal identifier; or, it can determine the target beam based on the beam identifier of the beam used by the physical channel.

[0113] By adopting the above scheme, the network control repeater receives the binding relationship between the backhaul link and the target physical channel in the network control repeater in the beam information sent by the network device, and determines the target beam used by the channel bound to the backhaul link according to the binding relationship. There is no need to test the multiple beams one by one, so that the backhaul link can quickly determine the beam with better performance, effectively improving the efficiency and performance of communication.

[0114] Figure 7 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 7 As shown, the method includes:

[0115] S701. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information; wherein the beam indication information includes a binding relationship between the backhaul link and a target physical channel in the network control repeater.

[0116] S702: The network control repeater determines, according to the binding relationship, a first beam used by a target physical channel from a plurality of beams configured by the network device for a control link of the network control repeater.

[0117] S703: The network controls the repeater to use the first beam as the target beam.

[0118] S704, the network controls the repeater to determine a first time for applying the first beam to the target physical channel;

[0119] S705. The network controls the repeater to determine the first time as the effective time of the backhaul link using the target beam.

[0120] The network device may be a base station or a high-level network device, and the signaling may be RRC signaling sent by the base station in a unicast or multicast manner, or may be signaling carried in an OAM message sent by a high-level network device, which is not limited in the embodiments of the present disclosure.

[0121] It can be understood that, in the embodiment of the present disclosure, the first beam used by the target physical channel may be a beam that the target physical channel is about to use but has not yet started to use.

[0122] By adopting the above scheme, 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 consistent with 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.

[0123] Figure 8 is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Figure 8 As shown, the method includes:

[0172] Fig.13is a flow chart of a beam indication method for a backhaul link according to an exemplary embodiment, which is applied to a network control repeater, such as Fig.13 As shown, the method includes:

[0173] S1301. A network control repeater receives a signaling sent by a network device for configuring a beam of a backhaul link, where the signaling includes beam indication information.

[0174] S1302: The network control repeater determines, according to the beam indication information, 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.

[0180] In some optional embodiments, when the network controls the repeater to determine that the target beam includes two beams, the network controls the repeater to perform downlink reception according to the first target beam in the target beams and perform uplink transmission according to the second target beam.

[0181] Among them, the first target beam and the second target beam can be randomly selected by the network relay controller from the two beams included in the target beam, or can be selected according to a preset rule, and the present disclosure does not limit this.

[0185] The network device may be a base station or a high-level network device, and the target beam may be a beam with better communication performance predetermined by the network device based on the communication quality of multiple beams communicating with the control link of the network control repeater.

When only one beam is indicated, the network control repeater can use the beam for uplink transmission and downlink reception.

And, according to the information included in the beam indication information, determine the effective time of the target beam.

[0192] Further, as mentioned above Figure 8-Figure 13 In the provided embodiment, the network relay controller can also determine, based on predefined rules, the beam used by the backhaul link of the network relay controller before receiving the signaling sent by the network device to configure the beam of the backhaul link, and / or before the target beam takes effect.

[0193] In the disclosed embodiment, the network device sends a signal for configuring the beam of the backhaul link to the network control repeater, so that the network control repeater can directly select a beam with better performance from multiple beams pre-configured by the network device for the control link based on the beam indication information in the signal. The network control repeater does not need to test the multiple beams one by one, but can quickly determine the beam with better performance for the backhaul link, thereby effectively improving the efficiency and performance of communication.

[0194] Those skilled in the art can understand that the aforementioned multiple embodiments executed by the network control repeater and the multiple embodiments executed by the network device correspond to each other, so the corresponding steps may be described only on one side, and the other side must perform the corresponding operation. For example, the network device sends a signaling for configuring the beam of the backhaul link to the network control repeater by broadcasting or unicasting or multicasting; then the terminal must receive the signaling in a corresponding manner.
