[0014] In the prior art, a relay node is disposed between a sending node and a receiving node and can control the channel between the sending node and the receiving node. However, in some cases, the interaction command between the relay node and the sending node usually depends on the relay node having high processing power, and for a relay node that does not have high processing power, the interaction process with the sending node has poor interaction effect and low reliability.

[0015] If the relay node is a Reconfigurable Intelligent Surface (RIS), the RIS is an artificial electromagnetic material with programmable electromagnetic properties. By controlling the phase of each array, the emitted beam can be focused to a desired direction or point, thereby realizing control of the electromagnetic environment. Meanwhile, the interaction command between the current base station and the RIS usually depends on the RIS's high processing power, and the specific transmission signaling and interface scheme have not been defined.

Therefore, the embodiments of the present application regulate the interaction interface and behavior between the transmitting node and the relay node, thereby realizing reliable and efficient communication between the transmitting node and the relay node.

[0023] In the embodiments of the present application, a base station is used as a transmitting node and a RIS is used as a relay node. However, those skilled in the art can understand that other types of transmitting nodes, such as a TRP or a gNB, or other types of relay nodes, such as a Smart Repeater, are also suitable for the node management method according to the embodiments of the present application.

[0024] 2 is a flowchart of a node management method performed by a relay node according to an embodiment of the present application. As shown in FIG. 2, the node management method may include, but is not limited to, step S1000 and step S2000.

[0025] Step S1000: When receiving a first cooperation signaling from a sending node, analyze the first cooperation signaling at a first pre-configured resource location according to a pre-received cooperation configuration command to obtain node management parameters.

[0026] In one embodiment, after receiving the cooperation configuration command in advance, the relay node may determine an analysis position of the cooperation signaling between the relay node and the transmitting node according to the cooperation configuration command. When the relay node receives the first cooperation signaling transmitted by the transmitting node, the relay node may analyze the first cooperation signaling at the first preset resource position determined by the cooperation configuration command to obtain the node management parameters in the first cooperation signaling.

[0027] In one embodiment, the above-mentioned cooperation configuration command may be configured by Radio Resource Control (RRC) or Medium Access Control (MAC) to define a specific time-frequency resource location for cooperation signaling, i.e., may be configured by Radio Resource Control or Medium Access Control and sent to the transmitting node and the relay node, where the cooperation configuration command may include, but is not limited to, at least one of the following: (1) Transmission frame number and slot number, (2) Symbol start position of the first cooperative signaling; (3) Symbol length of the first cooperative signaling; (4) a frequency domain starting position of the first cooperative signaling; (5) The number of frequency domain occupied resources for the first cooperative signaling; (6) a symbol start position of the second cooperation signaling for transmission to the transmitting node; (7) a symbol length of the second cooperation signaling to be sent to the sending node; (8) a frequency domain starting position of the second cooperation signaling for transmission to the transmitting node; (9) the number of frequency domain occupied resources of the second cooperative signaling to be transmitted to the transmitting node; (10) a frequency domain resource allocation status between a plurality of first cooperative signalings and a second cooperative signaling for transmission to a transmitting node; or (11) The number of delay slots or symbols of the second cooperative signaling to be transmitted to the transmitting node relative to the first cooperative signaling.

[0028] In one embodiment, the first cooperation signaling may be transmitted using a guard interval (GP) symbol as a dedicated communication command between the transmitting node and the relay node, i.e., the transmitting node may transmit the first cooperation signaling to the relay node using the guard interval symbol.

[0029] In one embodiment, the above first cooperation signaling may include, but is not limited to, at least one of the following: (1) a node indication identifier indicating the number of nodes that the first cooperation signaling corresponds to and controls; (2) a target identity identifier representing node identity information that the first coordination signaling corresponds to and controls; (3) a cell identity identifier; (4) System frame number, or (5) Node management parameters.

[0033] Step S2100: If the target identity identifier matches the preset identity identifier, manage the node according to the node management parameters.

[0034] In one embodiment, a preset identity identifier is preset in the relay node, and if the target identity identifier in the first cooperation signaling matches the preset identity identifier of the relay node, it indicates that the current relay node is the control target, and therefore the current relay node manages the node according to the node management parameters.

[0035] In one embodiment, the node management parameters in the first cooperation signaling may include, but are not limited to, at least one of the following: (1) an extended reference signal for timing synchronization, channel estimation, or power control; (2) State control parameters for controlling the operating state, or (3) A codebook identifier for determining a corresponding target codebook and generating a beam based on the target codebook.

[0039] Step S3100: Generate second cooperation signaling based on the first cooperation signaling.

[0040] Step S3200: According to the previously received cooperation configuration command, configure a second cooperation signaling in a second pre-configured resource location, and feed back the second cooperation signaling to the transmitting node.

[0041] In one embodiment, after receiving the first cooperation signaling from the transmitting node, the relay node further generates second cooperation signaling based on the first cooperation signaling, and the relay node determines an analysis position of the cooperation signaling between the relay node and the transmitting node according to the previously received cooperation configuration command, i.e., the relay node determines a second predetermined resource position according to the previously received cooperation configuration command, configures the second cooperation signaling at the second predetermined resource position, and feeds back the configured second cooperation signaling to the transmitting node.

[0042] In one embodiment, the approach by which the relay node feeds back the second cooperation signaling to the transmitting node may include, but is not limited to, the following approaches.

[0049] Step S4000: Establish a first cooperative signaling in a first pre-established resource location according to a pre-received cooperative establishment command.

[0050] Step S5000: Send the first cooperation signaling to the relay node, so that the relay node analyzes the first cooperation signaling at a first preset resource location to obtain node management parameters, and manages the node according to the node management parameters.

[0051] In one embodiment, after receiving a cooperation configuration command in advance, the transmitting node may determine an analysis position of the cooperation signaling between the relay node and the transmitting node according to the cooperation configuration command. After generating first cooperation signaling, the transmitting node may determine a first preset resource position in accordance with the cooperation configuration command in advance, configure the first cooperation signaling at the first preset resource position, and transmit the configured first cooperation signaling to the relay node. Then, after receiving the first cooperation signaling transmitted from the transmitting node, the relay node may analyze the first cooperation signaling at the first preset resource position determined by the cooperation configuration command to obtain node management parameters in the first cooperation signaling, and finally manage the node for itself based on the node management parameters.

[0052] In one embodiment, the above-mentioned cooperation configuration command may be configured by Radio Resource Control (RRC) or Medium Access Control (MAC) to define a specific time-frequency resource location for cooperation signaling, i.e., may be configured by Radio Resource Control or Medium Access Control and sent to the transmitting node and the relay node, where the cooperation configuration command may include, but is not limited to, at least one of the following: (1) Transmission frame number and slot number, (2) Symbol start position of the first cooperative signaling; (3) Symbol length of the first cooperative signaling; (4) a frequency domain starting position of the first cooperative signaling; (5) The number of frequency domain occupied resources for the first cooperative signaling; (6) a symbol start position of the second cooperation signaling for transmission to the transmitting node; (7) a symbol length of the second cooperation signaling to be sent to the sending node; (8) a frequency domain starting position of the second cooperation signaling for transmission to the transmitting node; (9) the number of frequency domain occupied resources of the second cooperative signaling to be transmitted to the transmitting node; (10) a frequency domain resource allocation status between a plurality of first cooperative signalings and a second cooperative signaling for transmission to a transmitting node; or (11) The number of delay slots or symbols of the second cooperative signaling to be transmitted to the transmitting node relative to the first cooperative signaling.

[0053] In one embodiment, the first cooperation signaling may be transmitted using a guard interval (GP) symbol as a dedicated communication command between the transmitting node and the relay node, i.e., the transmitting node may transmit the first cooperation signaling to the relay node using the guard interval symbol.

[0054] In one embodiment, the above first cooperation signaling may include, but is not limited to, at least one of the following: (1) a node indication identifier indicating the number of nodes that the first cooperation signaling corresponds to and controls; (2) a target identity identifier representing node identity information that the first coordination signaling corresponds to and controls; (3) a cell identity identifier; (4) System frame number, or (5) Node management parameters.

[0055] In one embodiment, the node management parameters in the first cooperation signaling may include, but are not limited to, at least one of the following: (1) an extended reference signal for timing synchronization, channel estimation, or power control; (2) State control parameters for controlling the operating state, or (3) A codebook identifier for determining a corresponding target codebook and generating a beam based on the target codebook.

[0057] In one embodiment, the above node management parameters may be pseudo-random sequences such as m-sequences, ZC sequences, PN sequences, etc.

[0058] In one embodiment, as shown in FIG. 6, FIG. 6 is a flowchart of a node management method according to one embodiment of the present application, in which in the above step S5000, after sending the first cooperation signaling to the relay node, the node management method further includes, but is not limited to, step S6100 and step S6200.

[0059] Step S6100: Receive second cooperation signaling fed back by the relay node based on the first cooperation signaling.

[0060] Step S6200: Analyze a second cooperation signaling at a second pre-configured resource location according to a pre-received cooperation configuration command.

[0061] In one embodiment, after receiving the first cooperation signaling from the transmitting node, the relay node further generates second cooperation signaling based on the first cooperation signaling, and the relay node determines an analysis position of the cooperation signaling between the relay node and the transmitting node according to the previously received cooperation configuration command, i.e., the relay node determines a second predetermined resource position according to the previously received cooperation configuration command, configures the second cooperation signaling at the second predetermined resource position, and feeds back the configured second cooperation signaling to the transmitting node, and further, the transmitting node determines a second predetermined resource position according to the previously received cooperation configuration command, and analyzes the second cooperation signaling at the second predetermined resource position.

[0062] In one embodiment, the approach by which the transmitting node receives the second cooperation signaling from the relay node may include, but is not limited to, the following approaches.

[0063] First approach: The relay node receives the second cooperation signaling fed back by the guard interval symbol.

[0064] Second approach: The relay node receives the second cooperation signaling fed back through the physical uplink channel.

[0067] In one embodiment, the first preset resource location and the second preset resource location may include at least one of a time domain location or a frequency domain location.

[0068] In the following, an embodiment of the present application is proposed based on the node management method executed by the relay node and the node management method executed by the sending node described above.

[0069] In an embodiment of the present application, an efficient, low-complexity, and reliable method for cooperation and interaction between a transmitting node and a relay node, such as a method for cooperation and interaction between a base station and a RIS, is proposed. Cooperation signaling is used to control the RIS to transmit a codebook ID, thereby realizing efficient communication between a base station and a single RIS or multiple RISs. The transmission is performed in a GP symbol position, and a cooperation configuration command defines the cooperation signaling time-frequency position and regulates the interaction interface and behavior between the base station and the RIS.

[0070] Regarding the time-frequency location of the cooperative signaling where the transmitting node and the relay node interact, the cooperative signaling is a dedicated communication command between the transmitting node and the relay node, and the cooperative setting command defines the specific time-frequency resource location of the cooperative signaling, is set by RRC or MAC, and is sent to the transmitting node and the relay node, and the cooperative setting command includes one or more of the following: (1) Transmission frame number and slot number, (2) Symbol start position of downlink cooperative signaling; (3) Symbol length of downlink cooperative signaling; (4) frequency domain starting position of downlink cooperative signaling; (5) The number of frequency domain occupied resources for downlink cooperative signaling; (6) Symbol start position of uplink cooperative signaling; (7) Symbol length of uplink cooperative signaling; (8) frequency domain starting position of uplink cooperative signaling; (9) The number of frequency domain occupied resources for uplink cooperative signaling; (10) Frequency domain resource allocation for multiple cooperative signaling in multi-relay node scenarios; (11) The number of delay slots or symbols for uplink cooperative signaling relative to downlink signaling.

[0071] Here, the downlink cooperative signaling is the first cooperative signaling described above, and the uplink cooperative signaling is the second cooperative signaling described above.

[0072] Also, as shown in Figure 7, Figure 7 is a schematic diagram of the transmission position of the cooperative signaling of the transmitting node and the relay node according to one embodiment of the present application, and the contents of the cooperative signaling such as downlink cooperative signaling and uplink cooperative signaling are as follows:

[0073] The cooperative signaling may be transmitted using a GP symbol as a dedicated communication command between the transmitting node and the relay node. The content of the downlink cooperative signaling transmitted by the transmitting node to the relay node includes one or more of the following, of which (4) to (6) are collectively referred to as cooperative function signaling: (1) Multi-relay node indication, which is a one-bit indication bit: indicates that the current cooperative signaling controls only a single relay node or multiple relay nodes. (2) the number or unique identification ID of the target relay node in the network; (3) Cell ID, system frame number, (4) Extended reference signal: Used for timing synchronization between the transmitting node and the relay node, channel estimation, automatic power control, etc. (5) Control commands: These include, but are not limited to, relay node on / off, restart, beam polling scan instructions, power control, detection cycle (how often the RIS monitors), mechanical adjustment of height tilt angle, and mode switching. Modes include energy-saving mode or normal mode, fixed beam or polling scan mode (fixed beam is a semi-static method, while polling scan mode is a dynamic scan method), codebook set flag (used to switch relay node codebook sets; multiple sets of codebooks may be stored on the RIS board side, supporting switching), etc. (6) Codebook ID: Used by the relay node side to analyze and activate the codebook number (after the RIS side analyzes the codebook number, it switches to the corresponding codebook and outputs the corresponding directional beam).

[0074] In a multi-RIS scenario, a corresponding number of cooperative function signalings are arranged according to the number of numbers, and the number of cooperative function signalings is equal to the number of numbers.

[0075] In addition, the signaling content of the uplink cooperative signaling sent by the relay node to the transmitting node includes one or more of the following, and this feedback signaling may be transmitted via a PUSCH channel or using HARQ in addition to being transmitted at the GP position: (1) The number or unique identification ID of the current relay node in the network; (2) Relay node reception synchronization, control or codebook ID success or failure indication: This feedback signaling may be placed in the PUSCH. (3) reporting the relay node's current codebook ID or operating mode; (4) Feedback of dysfunction.

[0076] Of these, the extended reference signal, control command, and codebook ID sequence may be transmitted using a pseudo-random sequence such as an m sequence, a ZC sequence, or a PN sequence.

[0077] The downlink cooperation signaling transmitted also includes a one-bit multi-RIS indication, which indicates whether the current cooperation signaling controls only one RIS or multiple RISs. When controlling multiple RISs, the downlink cooperation function signaling transmitted by the base station to multiple RISs and the uplink cooperation function signaling reported by the multiple RISs to the base station must be located in the same symbol where the cooperation signaling is present. The frequency domain resource allocation for the multiple RIS cooperation function signaling is defined in the cooperation configuration command. The RIS reads the target RIS number or ID in the cooperation signaling and compares it with its own. If its own number or ID is found in the transmitted cooperation signaling, it analyzes information such as the extended reference signal, control command, and codebook ID at the time-frequency position corresponding to the current RIS and activates the control command and codebook. If its own number or ID is not found in the cooperation signaling, no signaling analysis is performed.

[0078] In one embodiment, as shown in FIG. 8, FIG. 8 is a flowchart of the interaction between a transmitting node and a relay node according to one embodiment of the present application, where, for example, the transmitting node is a base station and the relay node is a RIS, the interaction process includes, but is not limited to, step S7100, step S7200, and step S7300.

[0079] Step S7100: The base station sends cooperative signaling to the RIS, sets and sends a specific transmission position through RRC or MAC, and sets cooperative signaling between the base station and the RIS at the corresponding GP symbol position. As shown in Figure 9, Figure 9 is a schematic diagram of setting cooperative signaling in a single relay node scenario according to an embodiment of the present application, which includes one or more of the following: (1) Multi-RIS indication, which is a one-bit indication bit: Here, it is set to 0, which indicates that only one RIS is controlled. (2) The number or unique identification ID of the target RIS in the network: The target RIS has a number in the network of x, and the receiving RIS compares its own number with x. If they are identical, it analyzes and activates the corresponding cooperation function signaling. (3) Cell ID, system frame number, (4) Extended reference signal: Used for timing synchronization between the base station and the RIS, channel estimation, automatic power control, etc., and transmitted using a pseudo-random sequence. (5) Control command: Set RIS to beam polling scanning mode, set codebook flag to 5, adjust horizontal tilt angle to 10 degrees, adjust height to -10 cm, and use energy-saving mode. (6) Codebook ID: Set the codebook ID as 150, that is, the 150-number codebook of the codebook set 5 number, and after analyzing the corresponding ID on the RIS side, apply this codebook to the RIS board and emit the corresponding directional beam.

[0080] Step S7200: The RIS receives the coordination signaling, analyzes it at the corresponding time-frequency position, and validates the control content therein. If the codebook instruction is included therein, the RIS board switches to the corresponding codebook.

[0081] Step S7300: The RIS feeds back to the base station cooperative signaling, including one or more of the following, where the feedback signaling may be transmitted via a PUSCH channel or using HARQ, in addition to being transmitted at the GP position: (1) The number or unique identification ID of the current RIS in the network: The number is x. (2) RIS reception synchronization, control or codebook ID success or failure indication: This feedback signaling may be placed on the PUSCH. (3) Report the current codebook ID or operation mode of the RIS: The current codebook ID is 150. (4) Feedback of dysfunction.

[0082] If the base station does not receive the successful reception feedback, it will retransmit the cooperation signaling, and after the cooperation is successful, start normal uplink and downlink services.

[0083] In one embodiment, the time-frequency resource location of the cooperative signaling is defined using a cooperative configuration command as follows: The cooperative configuration command defines a specific transmission time-frequency resource location of the cooperative signaling, and is configured by RRC or MAC and sent to the first node and the second node. In this embodiment, the first node may be a base station, and the second node may be a terminal, a RIS, or a smart repeater. Taking the RIS as an example, as shown in Figure 10, Figure 10 is a schematic diagram of the configuration of the first cooperative signaling and the second cooperative signaling according to one embodiment of the present application.

[0084] For example, the frequency domain starting position of downlink cooperative signaling is set to 100, the number of frequency domain resources is set to 127, the frame number is set to 5, the slot number is set to 13, the symbol starting position is set to 8, and the symbol length is set to 1, which indicates that the frequency domain RE position of the current cooperative signaling is 100 to 226 and the time domain occupies the 8th symbol of the 13th slot of the 5th frame. The frequency domain starting position of uplink cooperative signaling is set to 100, the number of frequency domain resources is set to 127, the frame number is set to 5, the slot number is set to 13, the symbol starting position is set to 11, and the symbol length is set to 1, which indicates that the frequency domain RE position of the current cooperative signaling is 100 to 226 and the time domain occupies the 11th symbol of the 13th slot of the 5th frame.

[0085] The base station sets downlink cooperation signaling at the corresponding position according to the instruction of the cooperation setting command and sends it to the RIS, and the RIS analyzes it at the corresponding time-frequency position; the RIS uploads uplink cooperation signaling at the indicated time-frequency position, and the base station analyzes it at the time-frequency position.

[0086] In one embodiment, the communication flow between a base station and a target RIS in a multi-RIS scenario is as follows: In this embodiment, the first node is a base station, and the second node may be a terminal, a RIS, or a smart repeater, taking the RIS as an example. The multi-RIS scenario indicates that multiple RISs are connected to one base station, or that there may be relays or cascades between multiple RISs. An example of a communication system in a multi-RIS scenario is shown in Figure 11, and multi-RIS cooperative signaling is shown in Figure 12.

[0087] As shown in FIG. 13, FIG. 13 is a flowchart of the interaction between a transmitting node and a relay node in a multiple relay node scenario according to one embodiment of the present application, and the interaction process includes, but is not limited to, steps S8100, S8200, S8300, S8400, and S8500.

[0088] Step S8100: The base station sets a multi-RIS indication (a 1-bit indication bit) in the transmitted cooperative signaling, defines that the current cooperative signaling controls multiple RISs, specifies the number or unique identification ID of the corresponding target RIS, and sets a cooperative function signaling with a corresponding number at a corresponding time-frequency position.

[0089] Step S8200: The base station sends cooperation signaling to the RIS, sets a specific transmission position by RRC or MAC, and transmits it at the corresponding GP symbol position or other time-frequency position.

[0090] Step S8300: The RIS receives and analyzes the cooperative signaling. If it is a single-RIS scenario, it directly analyzes and activates it according to embodiment 1; if it is a multi-RIS scenario, it determines whether its own number is included in the number set of the cooperative signaling. If it is not included, it does not analyze or activate the function.

[0091] Step S8400: If the analysis result indicates a multi-RIS scenario and the received cooperation signaling contains its own number or ID, read and analyze the cooperation function signaling at the frequency domain resource position corresponding to the number order, and enable the control content and codebook therein.

[0092] Step S8500: The RIS feeds back cooperation signaling to the base station, including one or more of the following: (1) The number or unique identifier of the current RIS in the network; (2) RIS reception synchronization, control or codebook ID success or failure indication: This feedback signaling may be placed in the PUSCH. (3) Report the current codebook ID or operating mode of the RIS (4) Feedback of dysfunction.

[0093] If the base station does not receive the successful reception feedback, it will retransmit the cooperation signaling, and after the cooperation is successful, start normal uplink and downlink services.
