[0051] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In one embodiment, as Figure 1 shown, a beam control method is provided. In this embodiment, it is exemplified that the method is applied to a base station and may include the following steps:

[0053] Step S101: Obtain the information type of the information to be transmitted and the capability information of the network control repeater corresponding to the information type; the information type includes any one of cell public information or user-specific information; the capability information of the network control repeater includes wide beam capability information corresponding to cell public information or narrow beam capability information corresponding to user-specific information.

[0054] Among them, the information to be transmitted may be information that needs to be transmitted by the NCR to the UE (User Equipment).

[0055] Among them, the capability information may include, but is not limited to, the maximum number of wide beams supported by the NCR for public information, the maximum number of narrow beams for UE-specific information, the NCR frequency band support capability (FR1 or FR2), and the NCR antenna port support capability. Among them, FR1 is the frequency band below 6 GHz, and FR2 is the millimeter wave frequency band.

[0056] Among them, the wide beam capability information may be, but is not limited to, the maximum number of wide beams for public information.

[0057] Among them, the narrow beam capability information can be, but is not limited to, the maximum number of narrow beams of UE-specific information.

[0058] Among them, the cell common information can be, but is not limited to, the MIB (Master Information Block), SIB1 (System Information Block 1), and Paging messages.

[0059] Among them, the user-specific information can be, but is not limited to, the PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), PUSCH (Physical Uplink Shared Channel), and UE-specific reference signals.

[0060] In a specific implementation, the NCR can report the information type of the information to be transmitted to the UE to the base station, and can also report the capability information of the NCR to the base station. The capability information may include wide beam capability information and narrow beam capability information.

[0061] Step S102, when the information type is cell common information, determine a wide beam indication message according to the wide beam capability information, and when the information type is user-specific information, determine a narrow beam indication message according to the narrow beam capability information.

[0062] Among them, the wide beam indication message can be the wide beam identifier corresponding to each UE for transmitting cell common information between the NCR and the UE.

[0063] Among them, the narrow beam indication message can be the beam pattern and time domain resources of the narrow beam used for transmitting user-specific information between the NCR and the UE.

[0064] Among them, the beam pattern can be the narrow beam identifier corresponding to each symbol in the time slot.

[0065] Among them, the time domain resources can be the start symbol and length of each segment of symbols in the time slot.

[0066] In a specific implementation, the base station can determine whether to use a wide beam or a narrow beam for transmission according to the information type of the information to be transmitted from the NCR to the UE. If the information type is cell common information, it is determined to use a wide beam for transmission, and a wide beam indication message for transmission using the wide beam is determined according to the obtained wide beam capability information; otherwise, if the information type is UE-specific information, it is determined to use a narrow beam for transmission, and a narrow beam indication message for transmission using the narrow beam is determined according to the obtained narrow beam capability information.

[0067] Step S103: Send a beam indication message to the network control repeater, so that the network control repeater performs beam control according to the received beam indication message. The beam indication message includes either a wide beam indication message or a narrow beam indication message.

[0068] In a specific implementation, after determining a wide beam indication message for transmission using a wide beam, the base station may send the wide beam indication message to the NCR. The NCR controls the wide beam for transmitting cell common information between the NCR and the UE according to the received wide beam indication message. After determining a narrow beam indication message for transmission using a narrow beam, the base station may also send the narrow beam indication message to the NCR. The NCR controls the narrow beam for transmitting UE-specific information between the NCR and the UE according to the received narrow beam indication message.

[0069] Figure 2 A flowchart showing the process of a base station controlling the wide and narrow beams of the NCR is provided. According to Figure 2 , the base station determines whether to use a wide beam or a narrow beam for transmission based on the specific information transmitted to the UE under the current NCR (S201). The specific determination method of the base station (S202) is as follows: If the information transmitted under the current NCR is cell common information, such as MIB, SIB1, and Paging messages, the base station determines it as cell common information and proceeds to step S203; if the information transmitted under the current NCR is UE-specific information, such as PDCCH, PDSCH, PUCCH, PUSCH, and UE-specific reference signals, it is determined as UE-specific information and proceeds to step S205. The base station decides to use a wide beam for transmitting cell common information MIB, SIB1, and Paging (S203); the base station notifies the NCR of the wide beam transmission mode through RRC signaling (S204). For UE-specific information, the base station decides to use a narrow beam for transmitting UE-specific information such as control channels, traffic channels, and reference signals (S205); the base station notifies the NCR of the beam transmission mode set through RRC signaling and dynamically indicates the specific beam transmission mode used through DCI (S206).

[0070] In the above beam control method, by obtaining the information type of the information to be transmitted and the capability information of the network control repeater corresponding to the information type, in the case where the information type is cell common information, a wide beam indication message is determined according to the wide beam capability information, and in the case where the information type is user-specific information, a narrow beam indication message is determined according to the narrow beam capability information, and the beam indication message is sent to the network control repeater; it enables the base station to control the beam between the network control repeater and the terminal according to different information types of the information to be transmitted, effectively expanding the coverage of the wireless network.

[0071] In one embodiment, the above step S101 may specifically include: sending a repeater access identifier to the network control repeater, so that the network control repeater establishes an RRC (Radio Resource Control) connection with the base station according to the received repeater access identifier, and returns an access confirmation message of the network control repeater in the case where the RRC connection is successfully established; in the case of receiving the access confirmation message of the network control repeater, sending a capability query message to the network control repeater, so that the network control repeater returns capability information according to the received capability query message.

[0072] Among them, the repeater access identifier may be an identifier used to indicate whether NCR access is allowed.

[0073] Among them, the access confirmation message may be a message used to indicate whether the current access is NCR.

[0074] Among them, the capability query message may be a message used to indicate a query of the capability information of NCR.

[0075] In a specific implementation, the base station may send an SIB1 message to the NCR. The SIB1 contains a repeater access identifier indicating whether NCR access is permitted. The repeater access identifier may be used to indicate whether NCR access is allowed. If the received repeater access identifier indicates that NCR access is not allowed, the NCR does not establish an RRC connection with the base station. Otherwise, if the received repeater access identifier indicates that NCR access is allowed, the NCR establishes an RRC connection with the base station and, when the RRC connection is successfully established, returns an access confirmation message to the base station. The base station may, in the case of receiving the access confirmation message sent by the NCR, send a capability query message to the NCR. The NCR may, in the case of receiving the capability query message, return the capability information of the NCR to the base station.

[0076] In practical applications, the base station sends an SSB (Synchronization Signal Block) to the NCR in a wide beam manner. The SSB contains MIB information for the initial access of the UE. The base station adds a field indicating whether the cell allows NCR access in the CellAccessRelatedInfo cell of the SIB1 information indicated by the MIB, and uses this field as the repeater access identifier to notify the NCR whether the current cell supports the NCR access function. Specifically as follows:

[0077] cellReservedForNCR ENUMERATED{true} OPTIONAL,

[0078] Among them, the field true indicates that NCR access is allowed. Otherwise, if the field is false, it indicates that NCR access is not allowed.

[0079] After NCR obtains the above field cellReservedForNCR from SIB1, it determines whether the current cell allows access. If access is allowed, it sends a MSG1:Random Access Preamble message to the base station to request access; the base station returns a MSG2:Random Access Response message to NCR; NCR sends a MSG3:RRCSetupRequest message to the base station; the base station sends a MSG4:RRCSetup message to NCR; NCR sends a MSG5:RRCSetupComplete message to the base station. A new cell is added to MSG5 to determine whether the current terminal is NCR, specifically as follows:

[0080] NCRIndication ENUMERATED{true}OPTIONAL;

[0081] The base station sends a UE capability query message UECapabilityEnquiry to NCR to obtain the maximum number of wide beams and narrow beams supported by NCR, the NCR frequency band support capability (FR1 or FR2), the number of transmit and receive antenna ports supported by NCR, etc.; NCR sends a UE capability query result UECapabilityInformation to the base station; 4 new cells are added to the UE capability information, specifically as follows:

[0082] NCR-WideBeam-NumbersDL ENUMERATED{4,8}OPTIONAL,

[0083] NCR-WideBeam-NumbersUL ENUMERATED{4,8}OPTIONAL,

[0084] NCR-NarrowBeam-NumbersDL ENUMERATED{8,16,32,64}OPTIONAL,

[0085] NCR-NarrowBeam-NumbersUL ENUMERATED{8,16,32,64}OPTIONAL.

[0086] In this embodiment, by sending a repeater access identifier to the network control repeater, the network control repeater is enabled to establish an RRC (Radio Resource Control) connection with the base station according to the received repeater access identifier, and in the case where the RRC connection is successfully established, return an access confirmation message of the network control repeater; in the case where the access confirmation message of the network control repeater is received, send a capability query message to the network control repeater, so that the network control repeater returns capability information according to the received capability query message, which can establish an RRC connection between the base station and the NCR in the case where the base station supports NCR access, and query the capability information of the NCR in the case where the RRC connection is successfully established, ensuring reliable communication between the base station and the NCR.

[0087] In one embodiment, the wide beam capability information includes the maximum number of wide beams; the above step S102 may specifically include: sending the maximum number of wide beams to the network control repeater, so that the network control repeater generates at least one wide beam according to the received maximum number of wide beams, sending the cell common information to the user terminal through at least one wide beam, and returning the target wide beam determined by the user terminal from at least one wide beam; determining the mapping relationship between the user terminal and the target wide beam as the wide beam indication message.

[0088] In specific implementation, the base station may send the maximum number of wide beams to the NCR, the NCR generates at least one wide beam according to the received maximum number of wide beams, the NCR may also send the cell common information to the UE through at least one wide beam, the UE may determine the target wide beam from at least one wide beam according to the received signal strength, return the identifier of the target wide beam to the base station through the NCR, the base station may record the target wide beam corresponding to each UE, and determine the corresponding relationship between each UE and the target wide beam as the wide beam indication message.

[0089] In practical applications, the base station notifies the NCR of the maximum number of beams for wide beam scanning in the RRCReconfiguration (RRC reconfiguration) message

[0090] maxNumberSSBBeam INTEGER(1..32);

[0091] The NCR decides the number of wide beam training SSBs based on the number of antenna ports and the current service scheduling situation; the NCR forwards the SSB information received from the base station in the way of wide beam scanning; the UE receives the SSB in the way of wide beam scanning; the UE determines the SSB beam ID to be accessed according to the strongest signal of the received SSB or the SSBs meeting a certain threshold; the UE initiates a Random Access Preamble on the uplink PRACH resource; the NCR determines the direction of the SSB where the UE is located according to the uplink resource accessed by the UE; the NCR notifies the gNB (the next Generation Node B) of the target wide beam ID where the current UE is located; the gNB stores the best wide beam ID between the NCR and the UE; the gNB notifies the SSB transmission beam pattern to the NCR through RRC signaling according to the best wide beam IDs where all UEs are located.

[0092] In this embodiment, by sending the maximum number of wide beams to the network control repeater, the network control repeater generates at least one wide beam according to the received maximum number of wide beams, sends the cell common information to the user terminal through at least one wide beam, and returns the target wide beam determined by the user terminal from at least one wide beam; the mapping relationship between the user terminal and the target wide beam is determined as the wide beam indication message, and the wide beam indication message can be determined according to the NCR capability information, so that the base station controls the wide beam between the NCR and the UE for the cell common information.

[0093] In one embodiment, the narrow beam capability information includes a narrow beam mode set; the above step S102 may specifically further include: sending the narrow beam mode set to the network control repeater, so that the network control repeater generates at least one narrow beam according to the received narrow beam mode set, sends the user-specific information to the user terminal through at least one narrow beam, and returns the target narrow beam determined by the user terminal from at least one narrow beam; the mapping relationship between the user terminal and the target narrow beam is determined as the narrow beam indication message.

[0094] Among them, the narrow beam mode set may be a set of narrow beam modes. Among them, the narrow beam mode may include the beam pattern of the narrow beam and the time domain resources corresponding to the narrow beam.

[0095] In a specific implementation, the base station may send a narrow beam mode set to the NCR. The NCR generates at least one narrow beam based on the received narrow beam mode set, and sends the user-specific message to the UE through the at least one narrow beam. The UE may determine the target narrow beam from the at least one narrow beam according to the received signal strength, and return the identifier of the target narrow beam to the base station through the NCR. The base station may record the target narrow beam corresponding to each UE, and determine the correspondence between each UE and the target narrow beam as the narrow beam indication message.

[0096] In practical applications, the base station notifies the NCR of the CSI-RS (Channel State Information Reference Signal) narrow beam mode set that can be used in the RRCReconfiguration message, which is represented by two tables: the beam index set and the time domain resource index set respectively; the NCR decides the number of narrow beam training CSI-RS based on the number of antenna ports and the current service scheduling situation; the NCR sends CSI-RS information in a narrow beam scanning manner; the UE receives the CSI-RS beam in a narrow beam scanning manner; the UE determines the CSI-RS beam ID to be accessed according to the strongest CSI-RS beam signal received or the CSI-RS beam signal that meets a certain threshold; the UE notifies the NCR of the narrow beam training result; the NCR determines the best beam ID for the NCR-UE specific information; the NCR notifies the gNB of the target best narrow beam ID where the current UE is located; the gNB saves the best narrow beam ID between the NCR and the UE; the gNB sends a narrow beam indication message to the NCR through DCI, and the following two new fields are added to the DCI:

[0097] Time domain resource indicator (Time domain resource indication message) – 5 bits

[0098] Beam indices indicator (Beam index indication message) – 6 bits;

[0099] In this embodiment, by sending the narrow beam mode set to the network control repeater, the network control repeater generates at least one narrow beam according to the received narrow beam mode set, sends the user-specific information to the user terminal through the at least one narrow beam, and returns the target narrow beam determined by the user terminal from the at least one narrow beam; the mapping relationship between the user terminal and the target narrow beam is determined as the narrow beam indication message, and the narrow beam indication message can be determined according to the NCR capability information, so that the base station controls the narrow beam between the NCR and the UE for the user-specific information.

[0100] In one embodiment, the narrow beam mode set includes a beam index set and a time domain resource set, and the narrow beam indication message includes a beam index indication message and a time domain resource indication message; the above step S103 may specifically include: sending the beam index indication message and the time domain resource indication message to the network control repeater through DCI (Downlink Control Information).

The narrow beam indication message may include a beam index indication message for indicating the beam index in the beam index set and a time domain resource indication message for indicating the time domain resource index in the time domain resource set.

[0104] In practical applications, the beam index set and the time domain resource set may be respectively represented as Table 1 and Table 2 below.

[0109] In this embodiment, by sending the beam index indication message and the time domain resource indication message to the network control repeater through DCI, when the NCR sends user-specific information, the base station can send the beam index indication message and the time domain resource indication message to the NCR, so that the NCR performs beam control according to the received beam index indication message and time domain resource indication message.

[0110] In one embodiment, after the step of sending the beam index indication message and the time domain resource indication message to the network control repeater through DCI, it may specifically further include: determining the number of activated terminals in the user terminal corresponding to the network control repeater; sending a shutdown message to the network control repeater when the number of activated terminals meets a preset condition; the preset condition includes that the number of activated terminals is zero.

[0111] In a specific implementation, an NCR can send user-specific information to at least one UE. For a specified NCR, the base station can determine the number of active UEs among the at least one UE corresponding to the NCR. If the number of active UEs meets a preset condition, for example, is zero, it can send a shutdown message to the NCR to notify the NCR to enter the shutdown state.

[0112] In practical applications, the gNB determines whether there are active UEs in the NCR; if there are no active UEs, it notifies the NCR to transition to the OFF state.

[0113] In this embodiment, by determining the number of active terminals among the user terminals corresponding to the network control repeater; and when the number of active terminals meets the preset condition, sending a shutdown message to the network control repeater, it is possible to notify the NCR to enter the shutdown state when there are no serving UEs in the NCR, thereby saving energy consumption.

[0114] To facilitate those skilled in the art to deeply understand the embodiments of the present application, the following will be described with a specific example.

[0115] In order to provide a method for NCR beam control so that the NCR and the UE can work properly in a beam manner to achieve the purpose of effectively expanding the wireless network coverage, a method for NCR beam control is proposed, and this method includes the following steps:

[0116] Step 1, the base station notifies the NCR in the SIB1 message whether the current cell supports NCR access, and the NCR notifies the base station in the access message 5 (MSG5) that the currently accessed terminal belongs to the NCR. The base station sends an NCR capability request message to the NCR through RRC signaling;

[0117] Step 2, the NCR reports NCR capability information to the base station, and the capability information includes: the maximum number of common information wide beams supported by the NCR, the maximum number of UE-specific information narrow beams; the NCR frequency band support capability (FR1 or FR2); the NCR antenna port support capability, etc.;

[0118] Step 3, after the base station obtains the reported capability information of the NCR, it respectively determines the maximum number of wide beams for the NCR to transmit common information and the maximum number of narrow beams for UE-specific information under the NCR; for the maximum number of wide beams of common information, the base station sends it to the NCR semi-statically through RRC signaling; for the narrow beams of UE-specific information, the base station dynamically notifies the NCR through a combination of RRC signaling and DCI; specifically, the base station notifies the NCR of the Sets of Beam ID Pattern and the Sets of Time Domain Information Pattern in the RRC signaling.

[0119] Step 4: The base station notifies the NCR to perform wide-beam scanning and transmission of public information. During the UE access process, the NCR obtains the SSB wide-beam ID where the UE is currently located based on the PRACH (Random Access Channel) resources used by the UE for access, and the NCR reports the SSB wide-beam ID where the current UE is located to the base station.

[0120] Step 5: The base station notifies the NCR to perform beam training on the currently accessed UE. The NCR performs narrow-beam scanning and transmission of the CSI-RS reference signal; the UE receives the CSI-RS reference signal in a narrow-beam scanning manner, and the UE takes the strongest received CSI-RS beam pair as the result of the NCR-UE beam training, and notifies the NCR of the beam training result by sending an uplink SRS reference signal.

[0121] Step 6: The NCR notifies the base station of the result of the beam training for the UE-specific information this time - the narrow-beam ID.

[0122] Step 7: The base station combines other scheduling information to decide the narrow-beam ID for the NCR to send service information this time, and notifies the NCR of the beam ID pattern (Beam ID Pattern) and time-domain information pattern (TimeDomain Information Pattern) used for this scheduling through DCI.

[0123] Step 8: When the base station determines that there is no scheduled user in the current NCR, it notifies the NCR to switch to the OFF mode through RRC signaling.

[0124] Figure 2 A flowchart showing the process of the base station controlling the narrow and wide beams of the NCR is provided. According to Figure 2 , the base station decides whether to use a wide beam or a narrow beam for transmission based on the specific information transmitted to the UE under the current NCR (S201). The specific decision method of the base station (S202): If the information transmitted under the current NCR is cell public information, such as MIB, SIB1, and Paging messages, the base station determines it as cell public information and proceeds to step S203; if the information transmitted under the current NCR is UE-specific information, such as PDCCH, PDSCH, PUCCH, PUSCH, and UE-specific reference signals, it is determined as UE-specific information and proceeds to step S205. The base station decides to use a wide beam for transmitting the cell public information MIB, SIB1, and Paging (S203); the base station notifies the NCR of the wide-beam transmission mode through RRC signaling (S204). For UE-specific information, the base station decides to use a narrow beam for transmitting UE-specific information such as control channels, service channels, and reference signals (S205); the base station notifies the NCR of the beam transmission mode set through RRC signaling and dynamically indicates the specific beam transmission mode used through DCI (S206).

[0125] Figure 3 A schematic diagram of the interaction link between a base station, an NCR, and a UE is provided. According to Figure 3 , side control information is exchanged between the base station and the NCR-MT (mobile terminal) through a control link. For an in-band network control repeater, the control link between the base station and the NCR is based on the NR air interface and is in the same frequency band as the feedback link; data is transmitted between the base station and the NCR-Fwd (forwarding) through the feedback link, and the NCR-Fwd has traditional radio frequency functions; the NCR-Fwd and the terminal interact through an access link. Through the access link between the NCR-Fwd and the terminal and the feedback link between the base station and the NCR-Fwd, data between the base station and the terminal is transmitted in a transparent manner.

According to Figure 4 , transmission is carried out between the base station (gNB) and the network control repeater (NCR) in a wide beam manner, mainly transmitting information such as MIB, SIB1, and Paging; transmission is also carried out between the network control repeater and the terminal in a wide beam manner, and the NCR forwards cell common information to UEs within the NCR coverage area through wide beam scanning. The wide beam transmission information between the base station, the network control repeater, and the terminal is updated semi-statically through RRC signaling.

[0127] Figure 5 A schematic diagram of narrow beam transmission between a base station, an NCR, and a UE is provided. According to Figure 5 , the base station transmits UE-specific information to the NCR in a narrow beam manner, such as PDCCH, PDSCH, PUCCH, PUSCH, and UE-specific reference signal CSI-RS, etc. After receiving the UE-specific information sent by the base station, the NCR transmits it to the UE in a narrow beam manner; the specific narrow beam ID (Beam ID) used is specified in the DCI sent by the base station to the NCR.
