[0050] To facilitate understanding, the terminology used in this application will be introduced first.

[0051] 1. Time-division multiplexing (TDM)

[0052] Time-division multiplexing (TDM) technology interleaves different signals into different time periods and transmits them along the same channel; at the receiving end, a method is used to extract the signals from each time period. This technology can transmit multiple signals on the same channel.

[0053] 2. Time-division duplex (TDD)

[0054] In TDD mobile communication systems, uplink and downlink communication between network devices and terminal devices uses different time slots on the same frequency channel (i.e., carrier). Time is used to separate the receive and transmit channels; during certain time periods, the base station transmits signals to the mobile station, and during other time periods, the mobile station transmits signals to the base station. Network devices and terminal devices must coordinate to operate smoothly.

[0055] 3. Smart Repeater

[0056] Intelligent repeaters are network-controlled repeater devices and are expected to become a key technology for extending cell coverage in Rel.18. They can be called 'network-controlled repeaters,' 'repeaters capable of directional signal amplification,' 'intelligent repeaters,' 'network-assisted repeaters,' 'controllable repeaters,' etc., and can be referred to as network-controlled repeaters. Intelligent repeaters operate in the second frequency band (FR2) and all operate in TDD mode. Unlike multiplexing, TDD means that uplink and downlink signals use different time intervals for transmission.

[0057] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system according to an embodiment. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1 The communication system shown is exemplified by a network device 11, an intelligent relay device 13, and a terminal device 12.

[0058] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems, etc.

[0059] The network device 11 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This embodiment does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0060] In this application embodiment, the terminal device 12 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0061] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0062] In typical intelligent relay communication scenarios, intelligent relays can be used to forward uplink signals sent from terminal devices to network devices and downlink signals sent from network devices to terminal devices. They can also be used to send their own generated uplink signals to network devices, such as feedback signals responding to control signals sent by network devices, or to receive downlink signals sent from network devices to the intelligent relay. When these four types of signals are multiplexed together using TDM technology, an uplink / downlink control method needs to be designed to indicate the sending and receiving actions of each signal at specific times to ensure the correctness of transmitted and received information. The following section, with reference to the accompanying drawings, provides a detailed description of an intelligent relay control method and apparatus provided in this application.

[0063] Please see Figure 2 , Figure 2 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0064] Step 201: Receive Time Division Duplex (TDD) configuration information sent by the network device, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0065] The first and second signals can be multiplexed together using TDM, frequency division multiplexing (FDM), or space division multiplexing (SDM), and this scheme does not impose any restrictions. The first signal can be an uplink or downlink signal that needs to be forwarded by the intelligent relay. For example, the first signal can be at least one of the following: an uplink signal sent by the forwarding terminal device, and a downlink signal sent by the forwarding network device. The second signal can be an uplink or downlink signal used for direct communication between the intelligent relay and the network device. For example, the second signal can be at least one of the following: an uplink signal sent by the intelligent relay to the network device for direct communication with the network device, and a downlink signal sent by the network device to the intelligent relay for direct communication with the intelligent relay.

[0066] Optionally, the TDD configuration information received by the smart relay indicates that its behavior is downlink. Alternatively, the TDD configuration information received by the smart relay indicates that its behavior is uplink. Or, the TDD configuration information received by the smart relay indicates that its behavior is downlink at certain specific times and / or uplink at certain specific times and / or uncertain at certain specific times, etc., and this disclosure does not limit this. Wherein, indicating its behavior is downlink means indicating that the smart relay's behavior is to receive downlink signals, and indicating its behavior is uplink means indicating that the smart relay's behavior is to transmit uplink signals.

[0067] Accordingly, when the smart relay receives the downlink action instruction, for the first signal, it can perform the action of forwarding the downlink signal of the base station at the corresponding time; for the second signal, it can perform the action of receiving the information of the base station and performing subsequent instruction demodulation and / or decoding at the corresponding time.

[0068] Alternatively, when the intelligent relay receives an uplink instruction, for the first signal, the intelligent relay performs the action of forwarding the uplink signal of the terminal device at the corresponding time; for the second signal, the intelligent relay performs the action of sending the uplink signal it generates, which has at least been modulated and / or encoded, to the network device at the corresponding time.

[0069] Typically, after establishing a connection with a network device, a smart repeater can receive TDD configuration information sent by the network device. This TDD configuration information includes instructions on the smart repeater's behavior towards a first signal and / or a second signal at a specific time. For example, in the TDD configuration information, D represents downlink, U represents uplink, and F represents unfixed (it can do both uplink and downlink), meaning the TDD information is applicable to both the first and second signals. Optionally, the TDD configuration information may also include TDM pattern information. For example, R represents forwarding information (the first signal), S represents information used for self-control (the second signal), and N indicates uncertainty regarding whether it is R or S.

[0070] for example Figure 3 As shown, Figure 3 This is an example diagram of TDD configuration information containing TDM patterns sent by network devices. Based on this TDD configuration information, the intelligent relay can receive the second signal (downlink signal from the network device) in slot #1, receive the first signal (forwarding the downlink signal from the network device) in slots 2-4, send the second signal (uplink signal generated by the intelligent relay itself) in slot 5, upload the first signal (forwarding the uplink signal from the terminal device) in slots 8-9, and the uplink / downlink status is uncertain in slots 6-7.

[0071] In this disclosure, the intelligent relay can forward uplink signals sent by the terminal device to the network device, or forward downlink signals sent by the network device to the terminal device. It can also send uplink signals generated by itself to the network device, such as feedback signals in response to signals sent by the network device, or receive downlink signals sent by the network device to the intelligent relay, such as control signals sent by the network device to the intelligent relay.

[0072] In this disclosure, the network device can configure information in the TDD configuration information instructing the smart relay to transmit and receive a first signal and / or a second signal at a specific time, and send the TDD configuration information to the smart relay. Thus, the smart relay can determine whether to perform uplink or downlink transmission at a specific time based on the TDD configuration information.

[0073] Optionally, when the configuration information does not indicate the uplink / downlink status of a signal corresponding to any specific time, the uplink signal corresponding to any specific time can be determined. Alternatively, when the configuration information does not indicate the uplink / downlink status of a signal corresponding to any specific time, the downlink signal corresponding to any specific time can be determined. For example, Figure 3 In the TDD configuration information shown, since slots #6 and #7 are not fixed, for smart relay, slots #6 and #7 can be considered as corresponding to downlink signals, or they can be considered as corresponding to uplink signals.

[0074] It should be noted that, if Figure 3 In the TDM pattern section of the TDD configuration information shown, if slot #6 corresponds to R, the intelligent relay can assume that slot #6 corresponds to either a downlink forwarding signal or an uplink forwarding signal. Conversely, if slot #6 corresponds to S in the TDM pattern section, the intelligent relay can assume that slot #6 corresponds to either a downlink self-control signal or an uplink self-control signal.

[0075] In addition, the TDD configuration information may not include the TDM pattern. In this case, the intelligent relay can receive the TDM pattern configured by the network device through other information to determine whether the uplink or downlink signal is the first signal or the second signal. This disclosure does not limit this.

[0076] In this disclosure, the intelligent relay can receive time-division duplex (TDD) configuration information sent by a network device, which instructs the intelligent relay to transmit and receive a first signal and / or a second signal at a specific time. Thus, by using the TDD configuration information, the transmission and reception behavior of each signal at a specific time can be determined, thereby enabling the intelligent relay to control each uplink and downlink signal and further ensuring the correctness of the transmitted and received information.

[0077] Please see Figure 4 , Figure 4This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0078] Step 401: Receive TDD configuration information sent by the network device via Radio Resource Control (RRC) signaling.

[0079] The TDD configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0080] Furthermore, for a detailed explanation of the first signal and the second signal, please refer to the detailed description of any embodiment of this disclosure, which will not be repeated here.

[0081] In this disclosure, the network device can configure TDD configuration information in RRC signaling. Thus, after the intelligent relay receives the RRC signaling sent by the network device, it can determine the TDD configuration information. Subsequently, based on the TDD configuration information, it can determine the sending and receiving behavior of the first signal and / or the second signal at a specific time and location.

[0082] Optionally, the smart trunk can also receive TDD configuration information sent by network devices via semi-static RRC signaling.

[0083] Optionally, the first signal and the second signal may correspond to different TDD configuration information, or the first signal and the second signal may correspond to the same TDD configuration information.

[0084] Optionally, the RRC signaling may further include a first signal identifier and / or a second signal identifier corresponding to each TDD configuration information, to indicate the correspondence between the first signal and the second signal and the TDD configuration information, respectively. The identifier can be any information that can uniquely identify a signal, such as carrier frequency information used to transmit the corresponding signal; this disclosure does not impose any limitations on this.

[0085] In this disclosure, after the intelligent relay establishes a connection with the network device, it can receive RRC signaling containing TDD configuration information sent by the network device. The TDD configuration information may include a corresponding first signal identifier or a second signal identifier. The configuration information may also include TDD configuration information, such as D indicating downlink, U indicating uplink, and F indicating unfixed (can be both uplink and downlink). This TDD configuration information is applicable to the first signal and the second signal respectively.

[0086] like Figure 5As shown, the TDD configuration information includes carrier frequency information for the first and second signals. CC#2 is used for forwarding, i.e., transmitting and receiving the first signal, while CC#1 is used for its own signal transmission and reception, i.e., transmitting and receiving the second signal. If the TDD configuration for the second signal is DFFFFUUFFFFDDUUU, then the intelligent relay receives the second signal (e.g., a physical downlink control channel (PDCCH) signal) in the first slot and demodulates it. In slots 2-5, it waits for further instructions from the network, and in slots 6-7, it transmits the second signal (e.g., an acknowledgement (ACK) / non-acknowledgement (NACK) signal). If the TDD configuration for the first signal is DDDDUUUDDDDDDDDU, then the intelligent relay can receive uplink signals from network devices in slots 1-4 and transmit uplink signals from terminal devices in slots 5-7.

[0087] In this disclosure, the intelligent relay can receive TDD configuration information sent by network devices through Radio Resource Control (RRC) signaling. Therefore, by using the TDD configuration information, the transmission and reception behavior of each signal at a specific time can be determined, thereby realizing the intelligent relay's control over each uplink and downlink signal and further ensuring the correctness of the transmitted and received information.

[0088] Please see Figure 6 , Figure 6 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0089] Step 601: Receive Time Division Duplex (TDD) configuration information sent by the network device, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0090] The specific implementation process of step 601 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0091] Step 602: Receive indication information sent by the network device through the media access control (MAC) or downlink control information (DCI), wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink / downlink signals corresponding to the time when the TDD configuration information does not indicate uplink / downlink status.

[0092] In this disclosure, after the network device sends TDD configuration information to the intelligent relay, it can also activate the TDD configuration information via indication information sent by MAC or DCI. The indication information may include identification information of the TDD configuration to be activated, thus allowing the intelligent relay to determine the activated TDD configuration based on the TDD configuration's identifier. The TDD configuration identifier can be any information that uniquely identifies the TDD configuration, such as a TDD configuration number.

[0093] Alternatively, after a network device assigns multiple TDD configuration information to a smart relay, it can also activate at least one of the multiple TDD configuration information through indication information sent by MAC or DCI.

[0094] Alternatively, after a network device activates the TDD configuration information via an indication message sent by MAC or DCI, it can also deactivate the TDD configuration information via an indication message sent by MAC or DCI. The deactivated TDD configuration information can be one or more.

[0095] In this disclosure, the network device can also indicate to the intelligent relay the uplink and downlink signals corresponding to time periods in the TDD configuration information where uplink and downlink status are not specified, via indication information sent by MAC or DCI. For example, such as Figure 4 As shown, at the 6th slot, the TDD configuration does not indicate the uplink / downlink status. At this time, the uplink / downlink status at the 6th slot can be indicated by the MAC CE and / or DCI commands.

[0096] Optionally, the uplink and downlink signals corresponding to the time periods in the TDD configuration information that do not indicate uplink and downlink status can be the uplink and downlink signals corresponding to one slot position, or they can be the TDD configurations corresponding to multiple consecutive symbol positions in one slot. This disclosure does not limit this.

[0097] like Figure 7 As shown, Figure 7Figure a shows an example of uplink / downlink signals corresponding to times in the TDD configuration information indicated by MAC or DCI that do not specify uplink / downlink status. Figure 7 In the TDD configuration, D, U, and F identify the specific details of the TDD configuration. D indicates receiving downlink signals, U indicates sending uplink signals, and F indicates uncertainty regarding uplink / downlink status. For example, the TDD configuration sent by the network device to the intelligent relay would be DDDDUFFUUU. Here, the uplink / downlink status is uncertain at the 7th slot time position. In this case, MAC or DCI can be used to further indicate the TDD configuration information corresponding to multiple consecutive symbols at the 7th slot time position, such as... Figure 7 As shown in b.

[0098] In this disclosure, after receiving Time Division Duplex (TDD) configuration information sent by the network device, which instructs the intelligent relay to transmit and receive the first and / or second signals at a specific time, the intelligent relay can also receive indication information sent by the network device via MAC or DCI to further configure the TDD settings. Therefore, by determining the transmission and reception of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the accuracy of transmitted and received information.

[0099] In this disclosure, the network device may assign one TDD configuration information to the first signal and multiple TDD configuration information to the second signal. Therefore, the network device may indicate the TDD configuration information corresponding to the first signal only through RRC signaling, indicate multiple TDD configuration information corresponding to the second signal through RRC signaling, and indicate the TDD configuration information to be used by the second signal through MAC or DCI.

[0100] Please see Figure 8 , Figure 8 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 8 As shown, the method may include, but is not limited to, the following steps:

[0101] Step 801: Receive TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling.

[0102] Optionally, two semi-static RRC signaling messages can be used to receive the TDD configuration information corresponding to the first signal sent by the network device and the multiple TDD configuration information corresponding to the second signal.

[0103] Step 802: Receive indication information corresponding to the second signal sent by the network device via MAC or DCI, wherein the indication information is used to activate at least one of the multiple TDD configuration information.

[0104] The specific implementation process of steps 801-802 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0105] In this disclosure, the intelligent relay, after receiving TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling, can receive indication information corresponding to the second signal sent by the network device via MAC or DCI, which is used to activate at least one of the multiple TDD configuration information. Therefore, by determining the sending and receiving behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the correctness of the transmitted and received information.

[0106] In this disclosure, the TDD configuration information corresponding to the first signal does not include time periods when uplink and downlink conditions are not indicated, while the TDD configuration information corresponding to the second signal may include time periods when uplink and downlink conditions are not indicated. Therefore, the network device can indicate the TDD configuration information corresponding to the first signal only through RRC signaling, indicate multiple TDD configuration information corresponding to the second signal through RRC signaling, and indicate the uplink and downlink signals corresponding to some time periods when uplink and downlink conditions are not indicated in the TDD configuration information corresponding to the second signal through MAC or DCI.

[0107] Please see Figure 9 , Figure 9 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 9 As shown, the method may include, but is not limited to, the following steps:

[0108] Step 901: Receive TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling.

[0109] Step 902: Receive indication information corresponding to the second signal sent by the network device via MAC or DCI, wherein the indication information is used to indicate to the smart relay the uplink and downlink signals corresponding to the time when the uplink and downlink status is not indicated in the TDD configuration information.

[0110] The specific implementation process of steps 901-902 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0111] In this disclosure, after receiving TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling, the intelligent relay can receive indication information corresponding to the second signal of the uplink / downlink signals sent by the network device via MAC or DCI. This indication is used to show the intelligent relay the time corresponding to the time when the uplink / downlink status in the TDD configuration information is not specified. Therefore, by determining the sending and receiving behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink / downlink signal, further ensuring the accuracy of the transmitted and received information.

[0112] In this disclosure, the first signal and the second signal may correspond to different TDD configuration information, and both the first signal and the second signal have relevant information that needs to be further indicated regarding the TDD configuration. For example, both the first signal and the second signal need to further indicate the uplink and downlink signals corresponding to some time periods in the TDD configuration information that do not indicate uplink and downlink status. The network device can indicate the TDD configuration information corresponding to the first signal and the second signal respectively through RRC signaling, and further indicate the relevant TDD configuration information corresponding to the first signal and the second signal respectively through MAC or DCI.

[0113] Please see Figure 10 , Figure 10 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 10 As shown, the method may include, but is not limited to, the following steps:

[0114] Step 1001: Receive TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling.

[0115] Step 1002: Receive indication information corresponding to the first signal sent by the network device via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink / downlink signal corresponding to the time when the uplink / downlink status is not indicated in part of the TDD configuration information.

[0116] Step 1003: Receive indication information corresponding to the second signal sent by the network device via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink / downlink signal corresponding to the time when the uplink / downlink status is not indicated in part of the TDD configuration information.

[0117] The specific implementation process of steps 1001-1003 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0118] In this disclosure, the intelligent relay can receive TDD configuration information corresponding to the first and second signals sent by the network device via semi-static RRC signaling. It can then receive indication information corresponding to the first signal and the second signal sent by the network device via MAC or DCI. Therefore, by determining the sending and receiving behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the accuracy of transmitted and received information.

[0119] In this disclosure, the first signal and the second signal may correspond to the same TDD configuration information, but the relevant information of the TDD configuration that the first signal and the second signal need to further indicate may be different. For example, the uplink and downlink signals corresponding to the time when the uplink and downlink status is not indicated in the TDD configuration information of the first signal and the second signal are different. The network device can indicate the TDD configuration information corresponding to the first signal and the second signal through RRC signaling, and further indicate the relevant information of the TDD configuration corresponding to the first signal and the second signal through MAC or DCI respectively.

[0120] Please see Figure 11 , Figure 11 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 11 As shown, the method may include, but is not limited to, the following steps:

[0121] Step 1101: Receive TDD configuration information sent by the network device via semi-static RRC signaling, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and the second signal at a specific time.

[0122] Step 1102: Receive indication information corresponding to the first signal sent by the network device via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink / downlink signal corresponding to the time when the uplink / downlink status is not indicated in part of the TDD configuration information.

[0123] Step 1103: Receive indication information corresponding to the second signal sent by the network device via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink / downlink signal corresponding to the time when the uplink / downlink status is not indicated in part of the TDD configuration information.

[0124] The specific implementation process of steps 1101-1103 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0125] In this disclosure, the intelligent relay can receive TDD configuration information sent by a network device via semi-static RRC signaling. This information instructs the intelligent relay to transmit and receive a first signal and a second signal at a specific time. Subsequently, it can receive indication information corresponding to the first signal sent by the network device via MAC or DCI, and also receive indication information corresponding to the second signal sent by the network device via MAC or DCI. Therefore, by determining the transmission and reception behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the accuracy of transmitted and received information.

[0126] Please see Figure 12 , Figure 12 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 12 As shown, the method may include, but is not limited to, the following steps:

[0127] Step 1201: Receive Time Division Duplex (TDD) configuration information sent by the network device, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0128] The specific implementation process of step 1201 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0129] Step 1202: In response to the first signal and / or the second signal being a downlink signal, the smart relay forwards the downlink signal of the network device to the terminal device at a specific time corresponding to the first signal, and / or receives the control signal sent by the network device at a specific time corresponding to the second signal, and performs at least demodulation and / or decoding processing on the control signal.

[0130] In this disclosure, when the intelligent relay determines that the first signal and / or the second signal are downlink signals based on the TDD configuration information, it can forward the downlink signal of the network device to the terminal device at the specific time corresponding to the first signal, and can receive the signal sent to the intelligent relay by the network device at the specific time corresponding to the second signal.

[0131] Step 1203: In response to the first signal and / or the second signal being an uplink signal, the smart relay forwards the uplink signal of the terminal device to the network device at a specific time corresponding to the first signal, and / or sends the uplink signal generated by itself, which has undergone at least demodulation and / or decoding, to the network device at a specific time corresponding to the second signal.

[0132] Optionally, the TDD configuration information may also instruct the smart relay on the behavior of the downlink first signal and / or second signal at a specific time, and may also instruct the smart relay on the behavior of the uplink first signal and / or second signal at a specific time. Thus, the smart relay can forward the first signal to the terminal device at the specific time corresponding to the downlink first signal; receive the second signal sent by the network device at the specific time corresponding to the downlink second signal, and perform demodulation and / or decoding processing on the second signal; forward the first signal to the network device at the specific time corresponding to the uplink first signal; and send its own generated uplink signal, which has undergone at least demodulation and / or decoding processing, to the network device at the specific time corresponding to the uplink second signal, such as sending the generated response signal to the network device, etc. This disclosure does not limit this.

[0133] In this disclosure, the intelligent relay, based on the uplink and downlink information corresponding to the first signal and / or the second signal in the TDD configuration information, performs a corresponding forwarding operation on the first signal at a specific time corresponding to the first signal, and transmits its own generated signal, which has undergone at least demodulation and / or decoding processing, at a specific time corresponding to the second signal. This achieves accurate processing of the first and / or second signals by the TDD intelligent relay, and enables reliable control of the TDD intelligent relay.

[0134] In this disclosure, after receiving Time Division Duplex (TDD) configuration information from a network device instructing the intelligent relay to transmit and receive a first signal and / or a second signal at a specific time, the intelligent relay, at the specific time corresponding to a downlink operation, forwards the downlink signal from the network device to the terminal device at the specific time corresponding to the first signal, and / or receives a control signal from the network device at the specific time corresponding to the second signal, and performs at least demodulation and / or decoding processing on the control signal. At the specific time corresponding to an uplink operation, the intelligent relay, at the specific time corresponding to the first signal, forwards the uplink signal from the terminal device to the network device, and / or, at the specific time corresponding to the second signal, sends its own generated uplink signal, which has undergone at least demodulation and / or decoding processing, to the network device. Thus, by determining the transmission and reception behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the correctness of transmitted and received information.

[0135] Please see Figure 13 , Figure 13 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. This method is executed by a network device. Figure 13 As shown, the method may include, but is not limited to, the following steps:

[0136] Step 1301: Send Time Division Duplex (TDD) configuration information to the smart relay, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0137] The first and second signals can be multiplexed together using TDM, frequency division multiplexing (FDM), or space division multiplexing (SDM), and this scheme does not impose any restrictions. The first signal can be an uplink or downlink signal that needs to be forwarded by the intelligent relay. For example, the first signal can be at least one of the following: an uplink signal sent by the forwarding terminal device, and a downlink signal sent by the forwarding network device. The second signal can be an uplink or downlink signal used for direct communication between the intelligent relay and the network device. For example, the second signal can be at least one of the following: an uplink signal sent by the intelligent relay to the network device for direct communication with the network device, and a downlink signal sent by the network device to the intelligent relay for direct communication with the intelligent relay.

[0138] Optionally, the TDD configuration information received by the smart relay indicates that its behavior is downlink. Alternatively, the TDD configuration information received by the smart relay indicates that its behavior is uplink. Or, the TDD configuration information received by the smart relay indicates that its behavior is downlink at certain specific times and / or uplink at certain specific times and / or uncertain at certain specific times, etc., and this disclosure does not limit this. Wherein, indicating its behavior is downlink means indicating that the smart relay's behavior is to receive downlink signals, and indicating its behavior is uplink means indicating that the smart relay's behavior is to transmit uplink signals.

[0139] Accordingly, when the smart relay receives the downlink action instruction, for the first signal, it can perform the action of forwarding the downlink signal of the base station at the corresponding time; for the second signal, it can perform the action of receiving the information of the base station and performing subsequent instruction demodulation and / or decoding at the corresponding time.

[0140] Alternatively, when the intelligent relay receives an uplink instruction, for the first signal, the intelligent relay performs the action of forwarding the uplink signal of the terminal device at the corresponding time; for the second signal, the intelligent relay performs the action of sending the uplink signal it generates, which has at least been modulated and / or encoded, to the network device at the corresponding time.

[0141] Typically, after establishing a connection with a smart relay, a network device can send TDD configuration information to the smart relay. This TDD configuration information includes instructions on the smart relay's behavior towards a first signal and / or a second signal at a specific time. For example, in the TDD configuration information, D represents downlink, U represents uplink, and F represents unfixed (it can be both uplink and downlink), meaning the TDD information is applicable to both the first and second signals. Optionally, the TDD configuration information can also include TDM pattern information. For example, R represents forwarding information (the first signal), S represents information used for self-control (the second signal), and N indicates uncertainty regarding whether it is R or S.

[0142] for example Figure 3 As shown, Figure 3 This is an example diagram of TDD configuration information containing TDM patterns sent by network devices. Based on this TDD configuration information, the intelligent relay can receive the second signal (downlink signal from the network device) in slot #1, receive the first signal (forwarding the downlink signal from the network device) in slots 2-4, send the second signal (uplink signal generated by the intelligent relay itself) in slot 5, upload the first signal (forwarding the uplink signal from the terminal device) in slots 8-9, and the uplink / downlink status is uncertain in slots 6-7.

[0143] In this disclosure, the intelligent relay can forward uplink signals sent by the terminal device to the network device, or forward downlink signals sent by the network device to the terminal device. It can also send uplink signals generated by itself to the network device, such as feedback signals in response to signals sent by the network device, or receive downlink signals sent by the network device to the intelligent relay, such as control signals sent by the network device to the intelligent relay.

[0144] In this disclosure, the network device can configure information in the TDD configuration information instructing the smart relay to transmit and receive a first signal and / or a second signal at a specific time, and send the TDD configuration information to the smart relay. Thus, the smart relay can determine whether to perform uplink or downlink transmission at a specific time based on the TDD configuration information.

[0145] Optionally, when the configuration information does not indicate the uplink / downlink status of a signal corresponding to any specific time, the uplink signal corresponding to any specific time can be determined. Alternatively, when the configuration information does not indicate the uplink / downlink status of a signal corresponding to any specific time, the downlink signal corresponding to any specific time can be determined. For example, Figure 3 In the TDD configuration information shown, since slots #6 and #7 are not fixed, for smart relay, slots #6 and #7 can be considered as corresponding to downlink signals, or they can be considered as corresponding to uplink signals.

[0146] It should be noted that, if Figure 3 In the TDM pattern section of the TDD configuration information shown, if slot #6 corresponds to R, the intelligent relay can assume that slot #6 corresponds to either a downlink forwarding signal or an uplink forwarding signal. Conversely, if slot #6 corresponds to S in the TDM pattern section, the intelligent relay can assume that slot #6 corresponds to either a downlink self-control signal or an uplink self-control signal.

[0147] In addition, the TDD configuration information may not include the TDM pattern. In this case, the intelligent relay can receive the TDM pattern configured by the network device through other information to determine whether the uplink or downlink signal is the first signal or the second signal. This disclosure does not limit this.

[0148] In this disclosure, the network device can send time-division duplex (TDD) configuration information to the smart relay to instruct the smart relay to transmit and receive the first signal and / or the second signal at a specific time. Thus, by using the TDD configuration information, the transmission and reception behavior of each signal at a specific time can be determined, thereby enabling the smart relay to control each uplink and downlink signal and further ensuring the correctness of the transmitted and received information.

[0149] Please see Figure 14 , Figure 14This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 14 As shown, the method may include, but is not limited to, the following steps:

[0150] Step 1401: Send TDD configuration information to the smart relay via Radio Resource Control (RRC) signaling.

[0151] The TDD configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0152] Furthermore, for a detailed explanation of the first signal and the second signal, please refer to the detailed description of any embodiment of this disclosure, which will not be repeated here.

[0153] In this disclosure, the network device can configure TDD configuration information in RRC signaling. Thus, after the intelligent relay receives the RRC signaling sent by the network device, it can determine the TDD configuration information. Subsequently, based on the TDD configuration information, it can determine the sending and receiving behavior of the first signal and / or the second signal at a specific time and location.

[0154] Optionally, network devices can also send TDD configuration information to intelligent trunks via semi-static RRC signaling.

[0155] Optionally, the first signal and the second signal may correspond to different TDD configuration information, or the first signal and the second signal may correspond to the same TDD configuration information.

[0156] Optionally, the RRC signaling may further include a first signal identifier and / or a second signal identifier corresponding to each TDD configuration information, to indicate the correspondence between the first signal and the second signal and the TDD configuration information, respectively. The identifier can be any information that can uniquely identify a signal, such as carrier frequency information used to transmit the corresponding signal; this disclosure does not impose any limitations on this.

[0157] In this disclosure, after establishing a connection with the smart relay, the network device can send RRC signaling containing TDD configuration information to the smart relay. The TDD configuration information may include a corresponding first signal identifier or a second signal identifier, and may also include TDD configuration information, such as D indicating downlink, U indicating uplink, and F indicating unfixed (capable of both uplink and downlink). This TDD configuration information is applicable to both the first and second signals respectively.

[0158] like Figure 5As shown, the TDD configuration information includes carrier frequency information for the first and second signals. CC#2 is used for forwarding, i.e., transmitting and receiving the first signal, while CC#1 is used for its own signal transmission and reception, i.e., transmitting and receiving the second signal. If the TDD configuration for the second signal is DFFFFUUFFFFDDUUU, then the intelligent relay receives the second signal (e.g., a physical downlink control channel (PDCCH) signal) in the first slot and demodulates it. In slots 2-5, it waits for further instructions from the network, and in slots 6-7, it transmits the second signal (e.g., an acknowledgement (ACK) / non-acknowledgement (NACK) signal). If the TDD configuration for the first signal is DDDDUUUDDDDDDDDU, then the intelligent relay can receive uplink signals from network devices in slots 1-4 and transmit uplink signals from terminal devices in slots 5-7.

[0159] In this disclosure, network devices can send TDD configuration information to intelligent relays via Radio Resource Control (RRC) signaling. By using the TDD configuration information, the sending and receiving behavior of each signal at a specific time can be determined, thereby enabling intelligent relays to control each uplink and downlink signal and further ensuring the correctness of the sending and receiving information.

[0160] Please see Figure 15 , Figure 15 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 15 As shown, the method may include, but is not limited to, the following steps:

[0161] Step 1501: Send Time Division Duplex (TDD) configuration information to the smart relay, wherein the configuration information is used to instruct the smart relay to send and receive the first signal and / or the second signal at a specific time.

[0162] The specific implementation process of step 1501 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0163] Step 1502: Send indication information to the smart relay via Media Access Control Unit (MAC) or Downlink Control Information (DCI). The indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink and downlink signals corresponding to the time when the uplink and downlink status is not indicated in the TDD configuration information.

[0164] In this disclosure, after the network device sends TDD configuration information to the intelligent relay, it can also activate the TDD configuration information via indication information sent by MAC or DCI. The indication information may include identification information of the TDD configuration to be activated, thus allowing the intelligent relay to determine the activated TDD configuration based on the TDD configuration's identifier. The TDD configuration identifier can be any information that uniquely identifies the TDD configuration, such as a TDD configuration number.

[0165] Alternatively, after a network device assigns multiple TDD configuration information to a smart relay, it can also activate at least one of the multiple TDD configuration information through indication information sent by MAC or DCI.

[0166] Alternatively, after a network device activates the TDD configuration information via an indication message sent by MAC or DCI, it can also deactivate the TDD configuration information via an indication message sent by MAC or DCI. The deactivated TDD configuration information can be one or more.

[0167] In this disclosure, the network device can also indicate to the intelligent relay the uplink and downlink signals corresponding to time periods in the TDD configuration information where uplink and downlink status are not specified, via indication information sent by MAC or DCI. For example, such as Figure 4 As shown, at the 6th slot, the TDD configuration does not indicate the uplink / downlink status. At this time, the uplink / downlink status at the 6th slot can be indicated by the MAC CE and / or DCI commands.

[0168] Optionally, the uplink and downlink signals corresponding to the time periods in the TDD configuration information that do not indicate uplink and downlink status can be the uplink and downlink signals corresponding to one slot position, or they can be the TDD configurations corresponding to multiple consecutive symbol positions in one slot. This disclosure does not limit this.

[0169] like Figure 7 As shown, Figure 7 Figure a shows an example of uplink / downlink signals corresponding to times in the TDD configuration information indicated by MAC or DCI that do not specify uplink / downlink status. Figure 7 In the TDD configuration, D, U, and F identify the specific details of the TDD configuration. D indicates receiving downlink signals, U indicates sending uplink signals, and F indicates uncertainty regarding uplink / downlink status. For example, the TDD configuration sent by the network device to the intelligent relay would be DDDDUFFUUU. Here, the uplink / downlink status is uncertain at the 7th slot time position. In this case, MAC or DCI can be used to further indicate the TDD configuration information corresponding to multiple consecutive symbols at the 7th slot time position, such as... Figure 7 As shown in b.

[0170] In this disclosure, after the network device sends Time Division Duplex (TDD) configuration information to the smart relay to instruct the smart relay to transmit and receive the first signal and / or the second signal at a specific time, it can further send indication information to the smart relay via MAC or DCI to configure the TDD settings. Thus, by determining the transmission and reception behavior of each signal at a specific time based on the TDD configuration information, the smart relay can control each uplink and downlink signal, further ensuring the accuracy of transmitted and received information.

[0171] In this disclosure, the network device may assign one TDD configuration information to the first signal and multiple TDD configuration information to the second signal. Therefore, the network device may indicate the TDD configuration information corresponding to the first signal only through RRC signaling, indicate multiple TDD configuration information corresponding to the second signal through RRC signaling, and indicate the TDD configuration information to be used by the second signal through MAC or DCI.

[0172] Please see Figure 16 , Figure 16 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 16 As shown, the method may include, but is not limited to, the following steps:

[0173] Step 1601: Send the TDD configuration information corresponding to the first signal and the second signal to the smart relay via semi-static RRC signaling.

[0174] Optionally, two semi-static RRC signaling messages can be used to send the TDD configuration information corresponding to the first signal and multiple TDD configuration information corresponding to the second signal to the smart relay.

[0175] Step 1602: Send indication information corresponding to the second signal to the smart relay via MAC or DCI, wherein the indication information is used to activate at least one of the multiple TDD configuration information.

[0176] The specific implementation process of steps 1601-1602 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0177] In this disclosure, after the network device sends TDD configuration information corresponding to the first and second signals to the intelligent relay via semi-static RRC signaling, it can send indication information corresponding to the second signal for activating at least one of the multiple TDD configuration information via MAC or DCI. Thus, by determining the sending and receiving behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the correctness of the transmitted and received information.

[0178] In this disclosure, the TDD configuration information corresponding to the first signal does not include time periods when uplink and downlink conditions are not indicated, while the TDD configuration information corresponding to the second signal may include time periods when uplink and downlink conditions are not indicated. Therefore, the network device can indicate the TDD configuration information corresponding to the first signal only through RRC signaling, indicate multiple TDD configuration information corresponding to the second signal through RRC signaling, and indicate the uplink and downlink signals corresponding to some time periods when uplink and downlink conditions are not indicated in the TDD configuration information corresponding to the second signal through MAC or DCI.

[0179] Please see Figure 17 , Figure 17 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 17 As shown, the method may include, but is not limited to, the following steps:

[0180] Step 1701: Send the TDD configuration information corresponding to the first signal and the second signal to the smart relay via semi-static RRC signaling.

[0181] Step 1702: Send indication information corresponding to the second signal to the smart relay via MAC or DCI. The indication information is used to indicate to the smart relay the uplink and downlink signals corresponding to the time periods in the TDD configuration information where uplink and downlink status are not indicated.

[0182] The specific implementation process of steps 1701-1702 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0183] In this disclosure, after the network device sends the TDD configuration information corresponding to the first and second signals to the intelligent relay via semi-static RRC signaling, it can send indication information corresponding to the second signal to the intelligent relay via MAC or DCI. This indication is used to show the intelligent relay the uplink and downlink signals for times when the uplink and downlink status is not specified in the TDD configuration information. Therefore, by determining the sending and receiving behavior of each signal at specific times based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the accuracy of the transmitted and received information.

[0184] In this disclosure, the first signal and the second signal may correspond to different TDD configuration information, and both the first signal and the second signal have relevant information that needs to be further indicated regarding the TDD configuration. For example, both the first signal and the second signal need to further indicate the uplink and downlink signals corresponding to some time periods in the TDD configuration information that do not indicate uplink and downlink status. The network device can indicate the TDD configuration information corresponding to the first signal and the second signal respectively through RRC signaling, and further indicate the relevant TDD configuration information corresponding to the first signal and the second signal respectively through MAC or DCI.

[0185] Please see Figure 18 , Figure 18 This is a flowchart illustrating a control method for an intelligent relay provided in an embodiment of this application. The method is executed by the intelligent relay. Figure 18 As shown, the method may include, but is not limited to, the following steps:

[0186] Step 1801: Send the TDD configuration information corresponding to the first signal and the second signal to the smart relay via semi-static RRC signaling.

[0187] Step 1802: Send indication information corresponding to the first signal to the smart relay via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink and downlink signals corresponding to the time when the uplink and downlink status is not indicated in part of the TDD configuration information.

[0188] Step 1803: Send indication information corresponding to the second signal to the smart relay via MAC or DCI, wherein the indication information is used to achieve any of the following: activate TDD configuration information, activate at least one of multiple TDD configuration information, deactivate TDD configuration information, deactivate at least one of multiple TDD configuration information, and indicate to the smart relay the uplink and downlink signals corresponding to the time when the uplink and downlink status is not indicated in part of the TDD configuration information.

[0189] The specific implementation process of steps 1801-1803 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0190] In this disclosure, the network device can send TDD configuration information corresponding to the first and second signals to the intelligent relay via semi-static RRC signaling, and then send indication information corresponding to the first signal to the intelligent relay via MAC or DCI. Subsequently, it sends indication information corresponding to the second signal to the intelligent relay via MAC or DCI. Thus, by determining the sending and receiving behavior of each signal at a specific time based on the TDD configuration information, the intelligent relay can control each uplink and downlink signal, further ensuring the accuracy of information transmission and reception.

[0191] In this disclosure, the first signal and the second signal may correspond to the same TDD configuration information, but the relevant information of the TDD configuration that the first signal and the second signal need to further indicate may be different.
