Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an information acquisition method, apparatus and storage medium. Background Technology

[0002] Mobile internet and the Internet of Things (IoT), as the two main drivers of future mobile communication development, provide a broad range of application scenarios for 5G (5th Generation Mobile Communication Technology). To meet the demands of more diverse, faster, and more numerous cellular network services in the future, cellular networks (such as 5G networks) need to significantly improve spectrum efficiency. Full-duplex technology is a key candidate technology for meeting the spectrum efficiency requirements of cellular networks (such as 5G networks).

[0003] Full-duplex technology refers to the simultaneous transmission of wireless services between near-end and far-end devices on the same frequency bandwidth at the same time. Compared to existing time-division duplex and frequency-division duplex technologies, it theoretically doubles the frequency efficiency. However, if full-duplex technology is applied to cellular networks, it may cause serious interference problems. Summary of the Invention

[0004] This disclosure provides an information acquisition method, apparatus, and storage medium applicable to Long Term Evolution (LTE) systems and 5G / NR (New Radio) systems. It enables network devices to know the full-duplex information of surrounding network devices, solves the interference problem caused by the application of full-duplex technology in cellular networking, and improves the spectrum efficiency of cellular networks.

[0005] In a first aspect, embodiments of this disclosure provide an information acquisition method applied to a network device, the method comprising:

[0006] The network device receives a first indication message sent by a first terminal device; wherein the first indication message is used to indicate to the network device that the first terminal device has recorded full-duplex information.

[0007] In this technical solution, the terminal device indicates to the network device that there is recorded network device information that supports full-duplex communication. This enables the network device to know that the surrounding network devices support full-duplex communication, so as to configure the appropriate full-duplex communication mode for the full-duplex terminal devices serving the network device. This can solve the interference problem caused by the application of full-duplex technology in cellular networking and also improve the spectrum efficiency of cellular networks.

[0008] In one implementation, the recorded full-duplex information is information about the network device's support for full-duplex communication, measured and recorded by the first terminal device based on the network device's configuration requirements when the device is in an idle state.

[0009] In this technical solution, the terminal device records the full-duplex information of a network device when it is in an idle state. When the terminal device establishes a connection with the network device, it informs the network device of the recorded full-duplex information, so that the network device can know that the surrounding network devices support full-duplex communication.

[0010] In one optional implementation, the method further includes: in response to the received first indication information, instructing the first terminal device to report the full-duplex information required by the network device; and receiving the reporting information sent by the first terminal device based on the indication.

[0011] In this technical solution, since the terminal device records full-duplex information, the network device can instruct the terminal device to report the full-duplex information required by the network device, so that the terminal device can report the full-duplex information to the network device based on the instruction.

[0012] In one optional implementation, the method further includes: configuring a corresponding full-duplex communication mode for a second terminal device serving the network device based on the reported information; wherein the second terminal device is a terminal device that supports full-duplex communication.

[0013] In this technical solution, the network device configures a suitable full-duplex communication mode for the full-duplex-enabled terminal device it serves based on the information reported by the terminal device. This enables the network device and the full-duplex-enabled terminal device to use the corresponding full-duplex communication mode, which can solve the interference problem caused by the application of full-duplex technology in cellular networking and also improve the spectrum efficiency of the cellular network.

[0014] In one optional implementation, instructing the first terminal device to report the full-duplex information required by the network device includes: instructing the first terminal device to report the full-duplex information required by the network device via a first type of RRC signaling message, according to the needs of the network device.

[0015] Optionally, the first type of RRC signaling message is added to the user equipment information request signaling message.

[0016] In one implementation, the method further includes: sending full-duplex information supported by the network device to a third terminal device via a system message.

[0017] Optionally, the method further includes: sending configuration information to the third terminal device in the connected state, the configuration information being used to notify the third terminal device to perform full-duplex measurement recording when in the idle state.

[0018] In this technical solution, network devices send their supported full-duplex information based on system messages to send configuration information to terminal devices in the connected state. This configuration information instructs the terminal devices to perform full-duplex measurement and recording when in the idle state. This allows the terminal devices to record the measured full-duplex information of the network devices. In the subsequent process of establishing a connection with a network device, the terminal devices can indicate to the network devices that they have recorded full-duplex information. This enables the network devices to know that surrounding network devices support full-duplex information, so as to configure appropriate full-duplex communication methods for the terminals served by the network devices.

[0019] In one alternative implementation, the system message is a minimal system message or other system messages.

[0020] In one implementation, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions.

[0021] Secondly, this disclosure provides another information acquisition method applied to a terminal device, the method comprising:

[0022] During the process of establishing a connection with the first network device, the terminal device is instructed to have recorded full-duplex information.

[0023] In this technical solution, during the process of establishing a connection with a network device, the terminal device indicates to the network device that it has recorded full-duplex information. This allows the terminal device to inform the network device of the recorded full-duplex information when establishing a connection with the network device, thereby enabling the network device to know that surrounding network devices support full-duplex communication.

[0024] In one implementation, the recorded full-duplex information is information about the second network device's support for full-duplex operation, measured and recorded by the terminal device in an idle state based on the configuration requirements of the second network device.

[0025] In this technical solution, when the terminal device is in an idle state, it measures and records the network device's full-duplex support information based on the network device's configuration requirements. This information is then used to indicate to the network device that the terminal device has recorded full-duplex information during the subsequent connection establishment process. When the terminal device establishes a connection with the network device, it informs the network device of the recorded full-duplex information, thereby allowing the network device to know that surrounding network devices support full-duplex communication.

[0026] In one implementation, instructing the first network device that the terminal device has recorded full-duplex information includes: instructing the first network device that the terminal device has recorded full-duplex information via a second type of RRC signaling message.

[0027] Optionally, the second type of RRC signaling message may be added to any of the following signaling messages: RRC connection setup complete signaling message; RRC connection reconfiguration complete signaling message; RRC connection reconstruction complete signaling message; RRC connection recovery complete signaling message.

[0028] In one implementation, the method further includes: receiving second indication information sent by the first network device; wherein the second indication information is used to instruct the terminal device to report full-duplex information required by the first network device; and sending reporting information to the first network device based on the indication information.

[0029] In this technical solution, since the terminal device records full-duplex information, the network device can instruct the terminal device to report the full-duplex information required by the network device, so that the terminal device can report the full-duplex information to the network device based on the instruction.

[0030] In one optional implementation, the first network device configures a corresponding full-duplex communication mode for the terminal devices supporting full-duplex communication that it serves, based on the reported information.

[0031] Optionally, the reported information is transmitted via user equipment information response signaling messages.

[0032] In this technical solution, the network device configures a suitable full-duplex communication mode for the full-duplex-enabled terminal device it serves based on the information reported by the terminal device. This enables the network device and the full-duplex-enabled terminal device to use the corresponding full-duplex communication mode, which can solve the interference problem caused by the application of full-duplex technology in cellular networking and also improve the spectrum efficiency of the cellular network.

[0033] In one implementation, when the terminal device is in an idle state, it measures and records information about the second network device's support for full-duplex based on the configuration requirements of the second network device, including: the terminal device receiving information about the full-duplex support of the second network device sent by the second network device through a system message.

[0034] In one optional implementation, when the terminal device is in an idle state, it measures and records the information that the second network device supports full-duplex based on the configuration requirements of the second network device, and further includes: the terminal device receiving configuration information configured by the second network device through unicast RRC signaling; after entering the idle state, the terminal device measures and records the information that the second network device supports full-duplex based on the configuration information.

[0035] In this technical solution, network devices send their supported full-duplex information based on system messages to send configuration information to terminal devices in the connected state. This configuration information instructs the terminal devices to perform full-duplex measurement and recording when in the idle state. This allows the terminal devices to record the measured full-duplex information of the network devices. In the subsequent process of establishing a connection with a network device, the terminal devices can indicate to the network devices that they have recorded full-duplex information. This enables the network devices to know that surrounding network devices support full-duplex information, so as to configure appropriate full-duplex communication methods for the terminals served by the network devices.

[0036] Optionally, the recorded full-duplex information includes at least: network device information that supports full-duplex communication; or, network device information that supports full-duplex communication and corresponding full-duplex information; or, network device information that has specific full-duplex conditions.

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.

[0072] The information acquisition method, apparatus, and storage medium provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0073] Please see Figure 2 , Figure 2 This is a flowchart illustrating an information acquisition method provided in an embodiment of this disclosure. It should be noted that the information acquisition method of this embodiment can be applied to network devices, wherein the network device is a network device that supports full-duplex communication. Figure 2 As shown, the method for obtaining this information may include, but is not limited to, the following steps.

[0074] Step S201: Receive first indication information sent by the first terminal device; wherein the first indication information is used to indicate to the network device that the first terminal device has recorded full-duplex information.

[0075] In some embodiments of this disclosure, the recorded full-duplex information may be information about the network device's support for full-duplex communication, measured and recorded by the first terminal device based on the network device's configuration requirements when it is in an idle state. In this embodiment, the network device configured to perform full-duplex measurement and recording for the first terminal device may be the network device receiving the first indication information sent by the first terminal device; alternatively, the network device configured to perform full-duplex measurement and recording for the first terminal device may also be other surrounding network devices.

[0076] For example, a network device supporting full-duplex communication sends its supported full-duplex information via a system message. This allows a first terminal device in an idle state to receive the system message, read the supported full-duplex information from it, and record it. Alternatively, the network device can configure full-duplex measurement and recording for a first terminal device in a connected state. Upon receiving this signaling, the first terminal device in a connected state, after entering an idle state, performs measurements and records according to the network device's configuration requirements. During subsequent connection establishment with another network device, the first terminal device can indicate its recorded full-duplex information. Upon receiving this indication, the network device understands that the first terminal device has recorded full-duplex information, allowing it to know that surrounding network devices support full-duplex communication. This enables the network device to configure appropriate full-duplex communication methods for the full-duplex terminal devices it serves, thus resolving interference issues arising from the application of full-duplex technology in cellular networks and improving the spectral efficiency of cellular networks.

[0077] Optionally, in this embodiment of the disclosure, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions. Wherein, the network device information can be understood as relevant information about the network device, such as the network device's identifier; the full-duplex information can be understood as full-duplex communication method information; and possessing specific full-duplex conditions can be understood to include at least one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex in one or more specified times, and supporting full-duplex in a specific mode.

[0078] It should be noted that the system message used by a network device to send full-duplex information supported by the network device to the first terminal device can be a Minimum System Message (MSI) or another system message (OtherSI). As an example, this system message can be a Minimum SI, which can be propagated using a broadcast mechanism. Minimum SIs typically include critical system messages related to cell selection and initial access (including obtaining OtherSIs). These system messages need to be propagated through periodic broadcasts, thus greatly compressing the information that needs to be broadcast.

[0079] As another example, the system message can be Other SI, such as all system messages other than the minimum system message. Other system messages are transmitted according to the requests of terminal devices or the needs of network devices, and can be transmitted using dedicated signaling, broadcast, or multicast, rather than being transmitted continuously and periodically, in order to improve resource utilization efficiency.

[0080] It should be noted that in some embodiments of this disclosure, the first terminal device may be a full-duplex supported terminal device. In other embodiments of this disclosure, the first terminal device may be a terminal device that does not support full-duplex but is capable of reading system messages sent by the network that contain full-duplex information of the network device.

[0081] For example, assuming the first terminal device is a full-duplex terminal device, the network device configures the first terminal device in the connected state to perform full-duplex measurement and recording. After receiving the configuration, the first terminal device in the connected state can perform measurements and recordings according to the network device's configuration requirements after entering the idle state, so that the first terminal device records the network device's full-duplex information.

[0082] For example, suppose the first terminal device does not support full-duplex but can read system messages sent by the network that contain full-duplex information of the network device. In this case, when the network device sends its supported full-duplex information through system messages, the first terminal device can read the full-duplex information supported by the network device from the system messages.

[0083] By implementing the embodiments of this disclosure, a terminal device can indicate to a network device that the terminal device has recorded network device information that supports full-duplex communication. This enables the network device to know the information of surrounding network devices that support full-duplex communication, so as to configure a suitable full-duplex communication mode for the full-duplex terminal devices serving the network device. This can solve the interference problem caused by the application of full-duplex technology in cellular networking and also improve the spectrum efficiency of cellular networks.

[0084] It should be noted that after receiving an instruction from the first terminal device, the network device can instruct the first terminal device to report the full-duplex information required by the network device, according to its own needs. Optionally, please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a flowchart of another information acquisition method provided in this disclosure. It should be noted that the information acquisition method of this disclosure can be applied to a network device that supports full-duplex communication. Figure 3 As shown, the method for obtaining this information may include, but is not limited to, the following steps.

[0085] Step S301: Receive first indication information sent by the first terminal device; wherein the first indication information is used to indicate to the network device that the first terminal device has recorded full-duplex information.

[0086] In some embodiments of this disclosure, the recorded full-duplex information may be information about the network device's support for full-duplex communication, measured and recorded by the first terminal device based on the network device's configuration requirements when it is in an idle state. In this embodiment, the network device configured to perform full-duplex measurement and recording for the first terminal device may be the network device receiving the first indication information sent by the first terminal device; alternatively, the network device configured to perform full-duplex measurement and recording for the first terminal device may also be other surrounding network devices.

[0087] For example, a network device supporting full-duplex communication sends its supported full-duplex information via a system message. This allows a first terminal device in an idle state to receive the system message, read the supported full-duplex information from it, and record it. Alternatively, the network device can configure full-duplex measurement and recording for a first terminal device in a connected state. Upon receiving this signaling, the first terminal device in a connected state, after entering an idle state, performs measurements and records according to the network device's configuration requirements. During subsequent connection establishment with another network device, the first terminal device can indicate its recorded full-duplex information. Upon receiving this indication, the network device understands that the first terminal device has recorded full-duplex information, allowing it to know that surrounding network devices support full-duplex communication. This enables the network device to configure appropriate full-duplex communication methods for the full-duplex terminal devices it serves, thus resolving interference issues arising from the application of full-duplex technology in cellular networks and improving the spectral efficiency of cellular networks.

[0088] Optionally, in this embodiment of the disclosure, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions. Wherein, the network device information can be understood as relevant information about the network device, such as the network device's identifier; the full-duplex information can be understood as full-duplex communication method information; and possessing specific full-duplex conditions can be understood to include at least one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex in one or more specified times, and supporting full-duplex in a specific mode.

[0089] It should be noted that the system message used by a network device to send full-duplex information supported by the network device to the first terminal device can be either a Minimum System Message (Minimum SI) or another system message (Other SI). As an example, this system message can be a Minimum SI, which can be propagated using a broadcast mechanism. Minimum SIs typically include critical system messages related to cell selection and initial access (including obtaining Other SIs). These system messages need to be propagated through periodic broadcasts, thus greatly compressing the information that needs to be broadcast.

[0090] As another example, the system message can be Other SI, such as all system messages other than the minimum system message. Other system messages are transmitted according to the requests of terminal devices or the needs of network devices, and can be transmitted using dedicated signaling, broadcast, or multicast, rather than being transmitted continuously and periodically, in order to improve resource utilization efficiency.

[0091] It should be noted that in some embodiments of this disclosure, the first terminal device may be a full-duplex supported terminal device. In other embodiments of this disclosure, the first terminal device may be a terminal device that does not support full-duplex but is capable of reading system messages sent by the network that contain full-duplex information of the network device.

[0092] For example, assuming the first terminal device is a full-duplex terminal device, the network device configures the first terminal device in the connected state to perform full-duplex measurement and recording. After receiving the configuration, the first terminal device in the connected state can perform measurements and recordings according to the network device's configuration requirements after entering the idle state, so that the first terminal device records the network device's full-duplex information.

[0093] For example, suppose the first terminal device does not support full-duplex but can read system messages sent by the network that contain full-duplex information of the network device. In this case, when the network device sends its supported full-duplex information through system messages, the first terminal device can read the full-duplex information supported by the network device from the system messages.

[0094] Step S302: In response to the received first instruction information, instruct the first terminal device to report the full-duplex information required by the network device.

[0095] In this embodiment of the disclosure, after receiving the first instruction information sent by the first terminal device, the network device can instruct the first terminal device to report the full-duplex information required by the network device according to its own needs. As an example, this requirement can be understood as the network device supporting full-duplex in one or more specified frequency bands, or the network device supporting full-duplex in one or more specified times, or the network device supporting full-duplex in a specific mode, etc.

[0096] Optionally, in this embodiment of the disclosure, the network device may instruct the first terminal device to report the full-duplex information required by the network device through a first type of RRC (Radio Resource Control) signaling message, and the first type of RRC signaling message may be added to the UE Information Request signaling message.

[0097] Step S303: Receive the reporting information sent by the first terminal device based on the instruction.

[0098] Optionally, after receiving an instruction from the network device, the first terminal device may report full-duplex information as required by the network device. This reported information may be transmitted via a User Equipment Information Response (UEInformationResponse) signaling message.

[0099] By implementing the embodiments of this disclosure, since the terminal device records full-duplex information, the network device can instruct the terminal device to report the full-duplex information required by the network device, so that the terminal device can report the full-duplex information to the network device based on the instruction.

[0100] It should be noted that the network device can configure a suitable full-duplex communication mode for the terminal devices it serves based on the information reported by the first terminal device, to ensure that the terminal devices and the network device can communicate normally. Optionally, please refer to [link to relevant documentation]. Figure 4 This is a flowchart of another information acquisition method provided in this disclosure. It should be noted that the information acquisition method of this disclosure can be applied to network devices that support full-duplex communication. Figure 4 As shown, the method for obtaining this information may include, but is not limited to, the following steps.

[0101] Step S401: Receive first indication information sent by the first terminal device; wherein the first indication information is used to indicate to the network device that the first terminal device has recorded full-duplex information.

[0102] In some embodiments of this disclosure, the recorded full-duplex information may be information about the network device's support for full-duplex communication, measured and recorded by the first terminal device based on the network device's configuration requirements when it is in an idle state. In this embodiment, the network device configured to perform full-duplex measurement and recording for the first terminal device may be the network device receiving the first indication information sent by the first terminal device; alternatively, the network device configured to perform full-duplex measurement and recording for the first terminal device may also be other surrounding network devices.

[0103] For example, a network device supporting full-duplex communication sends its supported full-duplex information via a system message. This allows a first terminal device in an idle state to receive the system message, read the supported full-duplex information from it, and record it. Alternatively, the network device can configure full-duplex measurement and recording for a first terminal device in a connected state. Upon receiving this signaling, the first terminal device in a connected state, after entering an idle state, performs measurements and records according to the network device's configuration requirements. During subsequent connection establishment with another network device, the first terminal device can indicate its recorded full-duplex information. Upon receiving this indication, the network device understands that the first terminal device has recorded full-duplex information, allowing it to know that surrounding network devices support full-duplex communication. This enables the network device to configure appropriate full-duplex communication methods for the full-duplex terminal devices it serves, thus resolving interference issues arising from the application of full-duplex technology in cellular networks and improving the spectral efficiency of cellular networks.

[0104] Optionally, in this embodiment of the disclosure, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions. Wherein, the network device information can be understood as relevant information about the network device, such as the network device's identifier; the full-duplex information can be understood as full-duplex communication method information; and possessing specific full-duplex conditions can be understood to include at least one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex in one or more specified times, and supporting full-duplex in a specific mode.

[0105] It should be noted that the system message used by a network device to send full-duplex information supported by the network device to the first terminal device can be either a Minimum System Message (Minimum SI) or another system message (Other SI). As an example, this system message can be a Minimum SI, which can be propagated using a broadcast mechanism. Minimum SIs typically include critical system messages related to cell selection and initial access (including obtaining Other SIs). These system messages need to be propagated through periodic broadcasts, thus greatly compressing the information that needs to be broadcast.

[0106] As another example, the system message can be Other SI, such as all system messages other than the minimum system message. Other system messages are transmitted according to the requests of terminal devices or the needs of network devices, and can be transmitted using dedicated signaling, broadcast, or multicast, rather than being transmitted continuously and periodically, in order to improve resource utilization efficiency.

[0107] It should be noted that in some embodiments of this disclosure, the first terminal device may be a full-duplex supported terminal device. In other embodiments of this disclosure, the first terminal device may be a terminal device that does not support full-duplex but is capable of reading system messages sent by the network that contain full-duplex information of the network device.

[0108] For example, assuming the first terminal device is a full-duplex terminal device, the network device configures the first terminal device in the connected state to perform full-duplex measurement and recording. After receiving the configuration, the first terminal device in the connected state can perform measurements and recordings according to the network device's configuration requirements after entering the idle state, so that the first terminal device records the network device's full-duplex information.

[0109] For example, suppose the first terminal device does not support full-duplex but can read system messages sent by the network that contain full-duplex information of the network device. In this case, when the network device sends its supported full-duplex information through system messages, the first terminal device can read the full-duplex information supported by the network device from the system messages.

[0110] Step S402: In response to the received first instruction information, instruct the first terminal device to report the full-duplex information required by the network device.

[0111] In this embodiment of the disclosure, after receiving the first instruction information sent by the first terminal device, the network device can instruct the first terminal device to report the full-duplex information required by the network device according to its own needs. As an example, this requirement can be understood as the network device supporting full-duplex in one or more specified frequency bands, or the network device supporting full-duplex in one or more specified times, or the network device supporting full-duplex in a specific mode, etc.

[0112] Optionally, in this embodiment of the disclosure, the network device may instruct the first terminal device to report the full-duplex information required by the network device through a first type of RRC signaling message, which may be added to the User Equipment Information Request (UEInformationRequest) signaling message.

[0113] Step S403: Receive the reporting information sent by the first terminal device based on the instruction.

[0114] Optionally, after receiving an instruction from the network device, the first terminal device may report full-duplex information as required by the network device. This reported information may be transmitted via a User Equipment Information Response (UEInformationResponse) signaling message.

[0115] Step S404: Configure the corresponding full-duplex communication mode for the second terminal device serving the network device according to the reported information.

[0116] In this embodiment of the disclosure, the second terminal device may be a terminal device that supports full-duplex communication.

[0117] In other words, after receiving the full-duplex information report sent by the first terminal device, the network device can configure a suitable full-duplex communication mode for the full-duplex communication-enabled terminal devices served by the network device based on this information. This full-duplex communication mode can be full-duplex communication in one or more specified frequency bands, full-duplex communication in one or more specified times, or full-duplex communication using a specific method.

[0118] By implementing the embodiments of this disclosure, a suitable full-duplex communication mode can be configured for the full-duplex-enabled terminal devices serving the network device based on the information reported by the terminal device. This enables the network device and the full-duplex-enabled terminal devices to use the corresponding full-duplex communication mode, which can solve the interference problem caused by the application of full-duplex technology in cellular networking and improve the spectrum efficiency of the cellular network.

[0119] It should be noted that, in some embodiments of this disclosure, a network device can send full-duplex information supported by the network device to a third terminal device via system messages. This allows the third terminal device connected to the network device to record the full-duplex information supported by the network device, so that the third terminal device can indicate the recorded full-duplex information to the network device during subsequent connection establishment. For example, a network device supporting full-duplex communication sends its supported full-duplex information via system messages. These system messages can be Minimum SIs, which can be propagated using a broadcast mechanism. Minimum SIs typically include critical system messages related to cell selection and initial access (including obtaining Other SIs). These system messages need to be propagated using periodic broadcasting, thereby greatly compressing the information that needs to be broadcast.

[0120] As another example, the system message can be Other SI, such as all system messages other than the minimum system message. Other system messages are transmitted according to the requests of terminal devices or the needs of network devices, and can be transmitted using dedicated signaling, broadcast, or multicast, rather than being transmitted continuously and periodically, in order to improve resource utilization efficiency.

[0121] In this embodiment of the disclosure, the third terminal device may be a full-duplex supported terminal device. In other embodiments of the disclosure, the third terminal device may be a terminal device that does not support full-duplex but is capable of reading system messages sent by the network that contain full-duplex information of network devices.

[0122] For example, assuming the third terminal device is a full-duplex supporting terminal device, after the network device sends the full-duplex information supported by the network device to the third terminal device through a system message, the third terminal device can read the full-duplex information supported by the network device from the system message, and thus can record the full-duplex information supported by the network device.

[0123] For example, suppose the third terminal device does not support full-duplex but can read system messages sent by the network that contain full-duplex information of the network device. In this case, when the network device sends its supported full-duplex information through system messages, the third terminal device can read the full-duplex information supported by the network device from the system messages.

[0124] It should be noted that, in other embodiments of this disclosure, the network device can send configuration information to a third terminal device in a connected state. This configuration information is used to notify the third terminal device to perform full-duplex measurement recording when in an idle state. In other words, the network device can use this configuration to inform the third terminal device to record the measured full-duplex information of the network device when in an idle state. As an example, the information measured and recorded by the third terminal device may include at least any of the following:

[0125] Measure and record information about network devices that support full-duplex communication;

[0126] Measure and record information about network devices that support full-duplex communication and the specific full-duplex information supported by the network device;

[0127] Measure and record information about full-duplex network devices that meet certain specific requirements; wherein, the full-duplex requirement can be one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex in one or more specified times, supporting full-duplex in a specific mode, etc.

[0128] By implementing the embodiments of this disclosure, a network device sends its supported full-duplex information based on a system message. Upon receiving this system message, a first terminal device in an idle state reads the supported full-duplex information from the system message and records it. Alternatively, the network device sends configuration information to a terminal device in a connected state. This configuration information instructs the terminal device to perform full-duplex measurement and recording when in an idle state. The terminal device records the measured full-duplex information of the network device. In this way, during subsequent connection establishment with another network device, the terminal device can indicate its recorded full-duplex information to the network device, allowing the network device to know that surrounding network devices support full-duplex communication and configure appropriate full-duplex communication methods for the terminals served by that network device.

[0129] It is understood that the above embodiments describe the implementation of the information acquisition method of this disclosure from the network device side. This disclosure also proposes another information acquisition method, which will be described below from the terminal device side. Please refer to... Figure 5 , Figure 5 This is a flowchart illustrating an information acquisition method provided in an embodiment of this disclosure. It should be noted that the information acquisition method of this embodiment can be applied to terminal devices. For example... Figure 5 As shown, the method for obtaining this information may include, but is not limited to, the following steps.

[0130] Step S501: During the process of establishing a connection with the first network device, the terminal device is instructed to have recorded full-duplex information.

[0131] In some embodiments of this disclosure, during the process of establishing a connection with a first network device, the terminal device can indicate to the first network device via a second type of RRC signaling message that the terminal device has recorded full-duplex information. As an example, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions. The possession of specific full-duplex conditions can be understood to include at least one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex at one or more specified times, and supporting full-duplex in a specific mode.

[0132] In one alternative implementation, the second type of RRC signaling message can be added to any of the following signaling messages: RRC connection setup complete signaling message; RRC connection reconfiguration complete signaling message; RRC connection reconstruction complete signaling message; RRC connection recovery complete signaling message.

[0133] It should be noted that the terminology for RRC connection setup complete signaling messages, RRC connection reconfiguration complete signaling messages, RRC connection re-establishment complete signaling messages, and RRC connection recovery complete signaling messages may differ across cellular network systems. For example, in a 4G network, this second type of RRC signaling message can be added to the following RRC connection setup complete signaling messages: RRCConnectionSetupComplete, RRCConnectionReconfigurationComplete, RRCConnectionReestablishmentComplete, and RRCConnectionResumeComplete. For example, in a 5G network, this second type of RRC signaling message can be added to the RRC connection setup complete signaling message; the RRC connection reconfiguration complete signaling message; the RRC connection reestablishment complete signaling message; and the RRC connection recovery complete signaling message.

[0134] It should be noted that, in this embodiment of the disclosure, the recorded full-duplex information can be obtained by the terminal device by reading a message sent by the network device containing full-duplex information supported by that network device. For example, a second network device supporting full-duplex communication sends its supported full-duplex information via a system message, so that the terminal device in an idle state, upon receiving the system message, can read the full-duplex information supported by the second network device from the system message and record the full-duplex information supported by the second network device. During the subsequent connection establishment process with the first network device, the terminal device can indicate to the first network device that the terminal device has recorded full-duplex information.

[0135] In other embodiments of this disclosure, the recorded full-duplex information may be information about the second network device's support for full-duplex operation, measured and recorded by the terminal device in an idle state based on the configuration requirements of the second network device. The first network device and the second network device may refer to the same network device, or they may refer to different network devices. For example, in this embodiment, the network device configured for full-duplex measurement and recording on the terminal device may be the same device as the network device receiving the indication information sent by the terminal device.

[0136] For example, a second network device configures full-duplex measurement recording for a terminal device in a connected state. The terminal device in the connected state receives configuration information from the second network device via unicast RRC signaling. After entering an idle state, it performs measurements based on this configuration information and records the second network device's support for full-duplex communication. This allows the terminal device to indicate to the first network device that it has recorded full-duplex information during subsequent connection establishment. Upon receiving this indication from the terminal device, the network device understands that the terminal device has recorded full-duplex information. This allows the network device to know that surrounding network devices support full-duplex communication, enabling it to configure appropriate full-duplex communication methods for the full-duplex-enabled terminal devices it serves. This can solve the interference problems caused by applying full-duplex technology to cellular networks and improve the spectrum efficiency of cellular networks.

[0137] By implementing the embodiments of this disclosure, during the connection establishment process between the terminal device and the network device, the terminal device indicates to the network device that it has recorded full-duplex information. This allows the terminal device to inform the network device of the recorded full-duplex information when establishing a connection, thereby enabling the network device to know that surrounding network devices support full-duplex communication. This allows the network device to configure appropriate full-duplex communication methods for the full-duplex terminal devices it serves. This can solve the interference problem caused by the application of full-duplex technology in cellular networking and also improve the spectrum efficiency of cellular networks.

[0138] It should be noted that the terminal device can receive the second indication information sent by the first network device, and based on the indication information, report the full-duplex information required by the first network device to the first network device, so that the first network device can configure a suitable full-duplex communication mode for the full-duplex communication-enabled terminal devices served by the first network device according to the information reported by the terminal device. Optionally, please refer to... Figure 6 , Figure 6 This is a flowchart illustrating yet another information acquisition method provided in this disclosure. It should be noted that the information acquisition method of this disclosure can be applied to terminal devices. For example... Figure 6As shown, the method for obtaining this information may include, but is not limited to, the following steps.

[0139] Step S601: During the process of establishing a connection with the first network device, the terminal device is instructed to have recorded full-duplex information.

[0140] In some embodiments of this disclosure, during the process of establishing a connection with a first network device, the terminal device can indicate to the first network device via a second type of RRC signaling message that the terminal device has recorded full-duplex information. As an example, the recorded full-duplex information includes at least: network device information supporting full-duplex communication; or, network device information supporting full-duplex communication and corresponding full-duplex information; or, network device information possessing specific full-duplex conditions. The possession of specific full-duplex conditions can be understood to include at least one or more of the following: supporting full-duplex in one or more specified frequency bands, supporting full-duplex at one or more specified times, and supporting full-duplex in a specific mode.

[0141] In one alternative implementation, the second type of RRC signaling message can be added to any of the following signaling messages: RRC connection setup complete signaling message; RRC connection reconfiguration complete signaling message; RRC connection reconstruction complete signaling message; RRC connection recovery complete signaling message.

[0142] It should be noted that the terminology for RRC connection setup complete signaling messages, RRC connection reconfiguration complete signaling messages, RRC connection re-establishment complete signaling messages, and RRC connection recovery complete signaling messages may differ across cellular network systems. For example, in a 4G network, this second type of RRC signaling message can be added to the following RRC connection setup complete signaling messages: RRCConnectionSetupComplete, RRCConnectionReconfigurationComplete, RRCConnectionReestablishmentComplete, and RRCConnectionResumeComplete. For example, in a 5G network, this second type of RRC signaling message can be added to the RRC connection setup complete signaling message; the RRC connection reconfiguration complete signaling message; the RRC connection reestablishment complete signaling message; and the RRC connection recovery complete signaling message.

[0143] It should be noted that, in this embodiment of the disclosure, the recorded full-duplex information can be obtained by the terminal device by reading a message sent by the network device containing full-duplex information supported by that network device. For example, a second network device supporting full-duplex communication sends its supported full-duplex information via a system message, so that the terminal device in an idle state, upon receiving the system message, can read the full-duplex information supported by the second network device from the system message and record the full-duplex information supported by the second network device. During the subsequent connection establishment process with the first network device, the terminal device can indicate to the first network device that the terminal device has recorded full-duplex information.

[0144] In other embodiments of this disclosure, the recorded full-duplex information may be information about the second network device's support for full-duplex operation, measured and recorded by the terminal device in an idle state based on the configuration requirements of the second network device. The first network device and the second network device may refer to the same network device, or they may refer to different network devices. For example, in this embodiment, the network device configured for full-duplex measurement and recording on the terminal device may be the same device as the network device receiving the indication information sent by the terminal device.

[0145] For example, a second network device configures full-duplex measurement recording for a terminal device in a connected state. The terminal device in the connected state receives configuration information from the second network device via unicast RRC signaling. After entering an idle state, it performs measurements based on this configuration information and records the second network device's support for full-duplex communication. This allows the terminal device to indicate to the first network device that it has recorded full-duplex information during subsequent connection establishment. Upon receiving this indication from the terminal device, the network device understands that the terminal device has recorded full-duplex information. This allows the network device to know that surrounding network devices support full-duplex communication, enabling it to configure appropriate full-duplex communication methods for the full-duplex-enabled terminal devices it serves. This can solve the interference problems caused by applying full-duplex technology to cellular networks and improve the spectrum efficiency of cellular networks.

[0146] Step S602: Receive second indication information sent by the first network device; wherein the second indication information is used to instruct the terminal device to report the full-duplex information required by the first network device.

[0147] Optionally, the first network device receives first indication information sent by the terminal device, wherein the first indication information is used to indicate to the first network device that the terminal device has recorded full-duplex information. After receiving the first indication information sent by the terminal device, the first network device instructs the terminal device to report the full-duplex information required by the first network device through a first type of RRC signaling message, which can be added to a UE Information Request signaling message.

[0148] Step S603: Send reporting information to the first network device based on the instruction information.

[0149] Optionally, after receiving an instruction (such as the second instruction information mentioned above) from the first network device, the terminal device may report full-duplex information according to the requirements of the first network device. This reported information can be transmitted via a User Equipment Information Response (UEInformationResponse) signaling message. After receiving the full-duplex information report from the terminal device, the first network device can configure a suitable full-duplex communication mode for the full-duplex communication-enabled terminal devices served by the first network device based on this information.

[0150] By implementing the embodiments of this disclosure, full-duplex information can be reported according to the requirements of the network device. After receiving the full-duplex information report from the terminal device, the network device can configure a suitable full-duplex communication method for the full-duplex-enabled terminal device it serves, so that the network device and the full-duplex-enabled terminal device can use the corresponding full-duplex communication method. This can solve the interference problem caused by the application of full-duplex technology in cellular networking and improve the spectrum efficiency of cellular networks.
