[0065] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0066] 1. Full-duplex communication

[0067] Full-duplex communication can be divided into frequency division multiplexing (FDM) and time division multiplexing (TDM).

[0068] FDM refers to the division of the entire transmission frequency band into several frequency channels, with each user occupying one frequency channel to transmit data, and guard bands left between frequency channels.

[0069] In addition, TDM refers to the ability to divide time into small time slices, each of which is further divided into several channels (time slots), and each user can occupy one channel to transmit data.

[0070] To better understand the networking method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0071] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, two or more access network devices. Figure 1 The number and form of the devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more access network devices may be included. Figure 1 The communication system shown is exemplified by a first access network device 11 and a second access network device 12.

[0072] It should be noted that the technical solutions of this disclosure can be applied to various communication systems, such as Long Term Evolution (LTE) systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0073] The first access network device 11 and the second access network device 12 in this disclosure are network-side entities used for transmitting or receiving signals. For example, the first access network device 11 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 disclosure does not limit the specific technology or device form used by the first access network device 11 and the second access network device 12.

[0074] The first access network device 11 and the second access network device 12 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. By adopting the CU-DU structure, the protocol layer of the first access network device, such as a base station, can be separated. Some of the protocol layer functions are placed in the CU for centralized control, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0075] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. 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 disclosure are also applicable to similar technical problems.

[0076] The networking method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0077] Please see Figure 2 , Figure 2 This is a flowchart illustrating a networking method provided in an embodiment of this disclosure, which is executed by a first access network device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0078] Step 21: Receive first indication information, wherein the first indication information is used to indicate the full-duplex communication information of the second access network device.

[0079] Typically, each access network device can perform full-duplex communication based on the full-duplex communication information it supports. If multiple access network devices simultaneously use the same full-duplex communication information for full-duplex communication, it may cause interference to the communication transmission, thereby affecting the communication transmission quality and efficiency.

[0080] In this embodiment, the first access network device can first receive first indication information, and then obtain the full-duplex communication information of the second access network device according to the indication of the first indication information. Therefore, when the first access network device performs full-duplex communication with the terminal device, it can minimize interference with the second access network device. This reduces interference during full-duplex communication by the access network devices, improving the quality and efficiency of communication transmission.

[0081] Optionally, the full-duplex communication information can be: whether the second access network device supports full-duplex.

[0082] For example, the first indication information suggests that the second access network device supports full-duplex communication. Upon receiving this first indication information, the first access network device can determine that the second access network device supports full-duplex communication. Therefore, the first access network device can determine that its full-duplex communication with the terminal device may be affected by the second access network device, and can then perform special processing as needed to minimize interference from the second access network device's full-duplex communication, thereby improving the quality and efficiency of communication transmission.

[0083] Optionally, the full-duplex communication information can be: information on the full-duplex capability supported by the second access network device.

[0084] Optionally, the full-duplex capability information supported by the second access network device may include at least one of the following: frequency resources for supported full-duplex; time domain resources for supported full-duplex; and type of supported full-duplex.

[0085] The full-duplex type can be either FDM or TDM.

[0086] For example, the first indication information indicates that the second access network device supports full-duplex frequency resource F1. Upon receiving this first indication information, the first access network device can determine that the second access network device supports full-duplex frequency resource F1. Therefore, when the first access network device conducts full-duplex communication with the terminal device, it can do so on a different frequency resource F2, minimizing interference caused by the second access network device's full-duplex communication and improving the quality and efficiency of communication transmission.

[0087] Alternatively, the first indication information indicates that the second access network device supports full-duplex frequency resource F1. Upon receiving this first indication information, the first access network device can determine that the second access network device supports full-duplex frequency resource F1. Therefore, when the first access network device communicates with the second access network device in full-duplex mode, it can do so on frequency resource F1, thereby improving the quality and efficiency of their communication transmission.

[0088] Alternatively, the first indication information indicates that the second access network device supports full-duplex time-domain resources T1. Upon receiving this first indication information, the first access network device can determine that the second access network device supports full-duplex time-domain resources T1. Therefore, when the first access network device performs full-duplex communication with the terminal device, it can do so on different time-domain resources T2, minimizing interference caused by the full-duplex communication of the second access network device, and improving the quality and efficiency of communication transmission.

[0089] Alternatively, the first indication information may indicate that the second access network device supports FDM full-duplex communication. Upon receiving this first indication information, the first access network device can determine that the second access network device supports FDM full-duplex communication based on the indication. Therefore, the first access network device can determine its full-duplex communication mode based on the full-duplex type supported by the second access network device and its own supported full-duplex type. For example, if the first access network device also supports FDM full-duplex communication, and its corresponding frequency bands are F1 and F2, then the first access network device can use either F1 or F2 for full-duplex communication. Correspondingly, the second access network device can use the other frequency band for full-duplex communication, thus minimizing interference during full-duplex communication and improving the quality and efficiency of communication transmission.

[0090] Alternatively, the first indication information may specify that the second access network device supports full-duplex frequency resource F1 and time domain resource T1. Upon receiving this first indication information, the first access network device can determine that the second access network device can utilize frequency resource F1 for full-duplex communication within time domain resource T1. Therefore, when the first access network device communicates with the terminal device in full-duplex mode, it can utilize frequency resource F1 within a time domain different from T1, or it can utilize frequency resources different from F1 within time domain resource T1, thereby minimizing interference caused by the full-duplex communication of the second access network device to the full-duplex communication of the first access network device, and improving the quality and efficiency of communication transmission.

[0091] Optionally, the full-duplex communication information can be: the configuration information of the full-duplex communication of the second access network device.

[0092] The configuration information for full-duplex communication may include which frequency resources can support full-duplex communication within which time resources, etc., and this disclosure does not limit this.

[0093] For example, the first indication information specifies that the full-duplex communication configuration information of the second access network device is: frequency resource F1 can support full-duplex communication within time resource T1 and frequency resource F3 within time resource T3. Upon receiving this first indication information, the first access network device can determine that the second access network device supports full-duplex communication with frequency resource F1 within time resource T1 and frequency resource F3 within time resource T3. Therefore, when the first access network device performs full-duplex communication with the terminal device, it can utilize frequency resource F1 within a time resource different from T1, or it can utilize frequency resources different from F1 within time resource T1, or it can utilize frequency resources different from F3 within time resource T3, or it can utilize frequency resources different from F3 within time resource T3. This minimizes interference caused by the full-duplex communication of the second access network device to the full-duplex communication of the first access network device, improving the quality and efficiency of communication transmission.

[0094] It should be noted that the first indication information may indicate one or more of the above, such as whether the second access network device supports full-duplex and the full-duplex capability information supported by the second access network device, or the first indication information may indicate whether the second access network device supports full-duplex, the full-duplex capability information supported by the second access network device, and the full-duplex communication configuration information of the second access network device, etc. This disclosure does not limit it in this respect.

[0095] By implementing the embodiments of this disclosure, the first access network device can obtain the full-duplex communication information of the second access network device based on the received first instruction information, thereby minimizing interference with the second access network device during full-duplex communication. This reduces interference during full-duplex communication by the access network device, improving the quality and efficiency of communication transmission.

[0096] Please see Figure 3 , Figure 3 This is a flowchart illustrating a networking method provided in an embodiment of this disclosure, which is executed by a first access network device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0097] Step 31: Send second indication information, wherein the second indication information is used to indicate the full-duplex communication information of the first access network device.

[0098] In this embodiment, the first access network device can send second indication information to the second access network device, enabling the second access network device to obtain the full-duplex communication information of the first access network device. This allows the second access network device to minimize interference with the first access network device during full-duplex communication with the terminal device. Consequently, interference during full-duplex communication by the access network device can be reduced, improving the quality and efficiency of communication transmission.

[0099] Alternatively, the first access network device can send a second indication message to other access network devices, enabling them to be aware of the first access network device's full-duplex communication information. This allows the other access network devices to minimize interference with the first access network device when communicating in full-duplex with terminal devices. Consequently, interference during full-duplex communication by access network devices can be reduced, improving the quality and efficiency of communication transmission.

[0100] Step 32: Receive first indication information, wherein the first indication information is used to indicate the full-duplex communication information of the second access network device.

[0101] It should be noted that the specific content and implementation method of step 32 can be referred to the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0102] Step 33: When it is determined that the full-duplex communication information of the first access network device has changed, the second indication information is sent through the next-generation access network device configuration update message.

[0103] Understandably, when the full-duplex communication information of the first access network device changes, the second indication information sent via the Next Generation Radio Access Network (NGRAN) node configuration update message can indicate the change in the first access network device's full-duplex communication information, or it can indicate the full-duplex communication information supported by the first access network device after the change, etc. Thus, other access network devices can be aware of the change in the first access network device's full-duplex communication information based on the second indication information, and consequently, when conducting full-duplex communication with terminal devices, they can minimize interference with the first access network device. This reduces interference during full-duplex communication by access network devices, improving the quality and efficiency of communication transmission.

[0104] Understandably, the NG RAN node configuration update message can be extended so that the second indication information carried in the message can indicate the full-duplex communication information of the first access network device.

[0105] For example, the protocol stipulates that a bit can be added to the NG RAN node configuration update message to indicate the full-duplex communication information of the first access network device. Thus, after receiving the NG RAN node configuration update message, other access network devices can determine the full-duplex communication information of the first access network device based on the newly added bit in the message, according to the protocol.

[0106] It should be noted that the above examples are merely illustrative and should not be construed as limiting the ways in which the interface establishment response messages are extended in the embodiments of this disclosure.

[0107] It should be noted that this disclosure does not limit the order of performing steps 32 and 33.

[0108] By implementing the embodiments of this disclosure, the first access network device can first send a second indication message to indicate its full-duplex communication information. Then, based on the received first indication message, it can obtain the full-duplex communication information of the second access network device. When it is determined that the full-duplex communication information of the first access network device has changed, the second indication message is sent via a next-generation access network device configuration update message. This minimizes interference during full-duplex communication by the access network devices, improving the quality and efficiency of communication transmission.

[0109] Please see Figure 4 , Figure 4 This is a flowchart illustrating a networking method provided in an embodiment of this disclosure, which is executed by a first access network device. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0110] Step 41: Establish a request message through the interface and receive the first indication information, wherein the first indication information is used to indicate the full-duplex communication information of the second access network device.

[0111] The interface setup request message can be an Xn setup request message, or it can be other interface setup request messages, etc. This disclosure does not limit it.

[0112] In this embodiment, the first access network device can establish a request message through an interface, receive first indication information, and then obtain the full-duplex communication information of the second access network device according to the indication information. Therefore, when the first access network device conducts full-duplex communication with the terminal device, it can minimize interference with the second access network device. This reduces interference during full-duplex communication by the access network devices, improving the quality and efficiency of communication transmission.

[0113] Optionally, the first indication information may be included in at least one of the following information elements: Serving Cell Information NR Information Element in Serving Cell List NR Information Element; Neighbor Cell Information NR Information Element in Serving Cell List NR Information Element; Evolved Universal Terrestrial Radio Access (E-UTRA) Information Element in Serving Cell List NR Information Element; Serving Cell Information E-UTRA Information Element in Serving Cell List E-UTRA Information Element; Neighbor Cell Information NR Information Element in Serving Cell List E-UTRA Information Element; Neighbor Cell Information E-UTRA Information Element in Serving Cell List E-UTRA Information Element; Designated Information Element in Serving Cell List NR Information Element; Designated Information Element in Serving Cell List E-UTRA Information Element.

[0114] It is understandable that the Served Cell Information NR information unit in the List of Served Cells NR information unit can be extended so that the Served Cell Information NR information unit can carry the first indication information.

[0115] For example, the protocol stipulates that a bit can be added to the "served cell information NR" information unit within the "list of served cells NR" information unit. This added bit indicates the full-duplex communication information of the second access network device. Therefore, after receiving the "served cell information NR" information unit from the "list of served cells NR" information unit, the first access network device can determine the full-duplex communication information of the second access network device based on the added bit in that information unit, according to the protocol.

[0116] It should be noted that the above examples are merely illustrative and should not be construed as limiting the ways in which the served cell information NR information unit in the list of served cells NR information unit in the embodiments of this disclosure can be extended.

[0117] Optionally, the neighbor information NR information unit in the list of served cells NR information unit can be extended so that the neighbor information NR information unit can carry the first indication information. The specific content and implementation process will not be described here.

[0118] Optionally, the neighbor information evolved universal terrestrial radio access (E-UTRA) information unit in the list of served cells NR information unit can be extended so that the neighbor information E-UTRA information unit can carry first indication information. The specific content and implementation process are not described here.

[0119] Optionally, the served cell information E-UTRA information unit in the list of served cells E-UTRA information unit can be expanded so that the served cell information E-UTRA information unit can carry first instruction information. The specific content and implementation process will not be described here.

[0120] Optionally, the neighborhood information NR information unit in the list of served cells E-UTRA information unit can be expanded so that the neighborhood information NR information unit can carry the first indication information. The specific content and implementation process will not be described here.

[0121] Optionally, the neighborhood information E-UTRA information unit in the list of served cells E-UTRA information unit can be expanded so that the neighborhood information E-UTRA information unit can carry the first instruction information. The specific content and implementation process will not be described here.

[0122] Optionally, a specified information unit can be added to the list of served cells NR information unit so that the specified information unit can carry the first indication information. The specific content and implementation process will not be described here.

[0123] Optionally, a specified information unit can be added to the list of served cells E-UTRA information units so that the specified information unit can carry the first instruction information. The specific content and implementation process will not be described here.

[0124] Step 42: Establish a response message through the interface and send the second indication information, wherein the second indication information is used to indicate the full-duplex communication information of the first access network device.

[0125] The interface establishment response message can be an Xn setup response message, or it can be a response message for other interfaces, etc. This disclosure does not limit it.

[0126] Understandably, the interface establishment response message can be extended to include a second indication message.

[0127] For example, the protocol stipulates that a bit can be added to the interface establishment response message to indicate the full-duplex communication information of the first access network device. Thus, after receiving the interface establishment response message, other access network devices can determine the full-duplex communication information of the first access network device based on the newly added bit in the message, according to the protocol.

[0128] It should be noted that the above examples are merely illustrative and should not be construed as limiting the ways in which the interface establishment response messages are extended in the embodiments of this disclosure.

[0129] Optionally, after learning of the full-duplex communication information of the second access network device, the first access network device can also indicate the full-duplex communication information of the second access network device to other access network devices. For example, the first access network device can send a second indication message so that other access network devices can learn about the full-duplex communication information of the first and second access network devices based on the second indication message. This allows other access network devices to minimize interference with the first and second access network devices when conducting full-duplex communication with terminal devices. Therefore, interference during full-duplex communication by access network devices can be minimized, improving the quality and efficiency of communication transmission.

[0130] By implementing the embodiments of this disclosure, the first access network device can establish a request message through an interface, receive first indication information, and then obtain the full-duplex communication information of the second access network device according to the indication of the first indication information. It can then establish a response message through the interface and send second indication information to indicate the full-duplex communication information of the first access network device. Therefore, interference during the use of full-duplex communication by the access network device can be minimized, improving the quality and efficiency of communication transmission.

[0131] Please see Figure 5 , Figure 5 This is a flowchart illustrating a networking method provided in an embodiment of this disclosure, which is executed by a first access network device. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0132] Step 51: Establish a request message through the interface and send the second indication information, wherein the second indication information is used to indicate the full-duplex communication information of the first access network device.

[0133] Step 52: Establish a response message through the interface and receive the first indication information, wherein the first indication information is used to indicate the full-duplex communication information of the second access network device.

[0134] Understandably, the first access network device can establish a response message through the interface, receive the first indication information, and then obtain the full-duplex communication information of the second access network device based on the indication information. Therefore, when the first access network device conducts full-duplex communication with the terminal device, it can minimize interference with the second access network device. This reduces interference during full-duplex communication by the access network devices, improving the quality and efficiency of communication transmission.

[0135] Optionally, the first indication information may be included in at least one of the following information elements: Serving Cell Information NR Information Element in Serving Cell List NR Information Element; Neighbor Cell Information NR Information Element in Serving Cell List NR Information Element; Evolved Universal Terrestrial Radio Access (E-UTRA) Information Element in Serving Cell List NR Information Element; Serving Cell Information E-UTRA Information Element in Serving Cell List E-UTRA Information Element; Neighbor Cell Information NR Information Element in Serving Cell List E-UTRA Information Element; Neighbor Cell Information E-UTRA Information Element in Serving Cell List E-UTRA Information Element; Designated Information Element in Serving Cell List NR Information Element; Designated Information Element in Serving Cell List E-UTRA Information Element.

[0136] It should be noted that the specific content and implementation method of the first instruction information may be included in at least one of the following information units, which can be referred to the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0137] By implementing the embodiments of this disclosure, the first access network device can establish a request message through an interface and send second indication information to indicate the full-duplex communication information of the first access network device. Subsequently, it can establish a response message through the interface, receive the first indication information, and then obtain the full-duplex communication information of the second access network device based on the indication of the first indication information. Therefore, interference with the second access network device can be minimized during full-duplex communication. This reduces interference during full-duplex communication by the access network device, improving the quality and efficiency of communication transmission.

[0138] Please see Figure 6 , Figure 6 This is a flowchart illustrating a networking method provided in an embodiment of this disclosure, which is executed by a first access network device. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0139] Step 61: Receive first indication information via a next-generation wireless access network device configuration update message, wherein the first indication information is used to indicate the full-duplex communication information of the second access network device.

[0140] Optionally, the first indication information may be included in at least one of the following information elements: the gNB information element in the NG RAN node configuration update message; and the next generation eNB (next generation eNodeB) information element in the NG RAN node configuration update message.

[0141] Understandably, the gNB information element in the NG RAN node configuration update message can be expanded to carry first indication information.

[0142] For example, the protocol stipulates that a bit can be added to the gNB information unit in the NG RAN node configuration update message to indicate the full-duplex communication information of the second access network device. Therefore, after receiving the gNB information unit in the NG RAN node configuration update message, the first access network device can determine the full-duplex communication information of the second access network device based on the newly added bit in the gNB information unit, according to the protocol.

[0143] It should be noted that the above examples are merely illustrative and should not be construed as limiting the ways in which gNB information elements in the NG RANnode configuration update message can be extended in the embodiments of this disclosure.

[0144] Alternatively, the ng eNB information unit in the NG RAN node configuration update message can be extended to carry first indication information. The specific content and implementation process will not be elaborated here.

[0145] Step 62: Communicate with the second access network device according to the first instruction information and the full-duplex communication information of the first access network device.

[0146] For example, if the first access network device learns from the first instruction information that the second access network device supports full-duplex time-domain resources T1, and the first access network device supports full-duplex time-domain resources T1, T3, and T4, then when the first access network device communicates with the second access network device in full-duplex mode, it can do so on time-domain resource T1, thereby improving the quality and efficiency of their communication transmission. This disclosure does not limit this aspect.

[0147] By implementing the embodiments of this disclosure, a first access network device can receive first indication information via a next-generation wireless access network device configuration update message, and then communicate with a second access network device based on the first indication information and the full-duplex communication information of the first access network device.
