[0082] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0083] With the continuous development of wireless communications, the demand for communication capabilities is increasing. For future application scenarios such as AR / VR, the Internet of Vehicles, and the Internet of Things, ultra-high-speed, ultra-low-latency, and ultra-large-bandwidth communications will become the norm. Due to the characteristics of OAM communication, OAM communication has the potential to be applied in ultra-high-speed, ultra-low-latency, and ultra-large-bandwidth mobile communications. In mobile communication systems, the transmission of some target signals or control signaling requires extremely high reliability, which necessitates high transmission quality. In OAM communication, how to transmit target signals or control signaling in a highly reliable channel is a pressing issue.

[0084] To this end, the present disclosure proposes an OAM mode indication method and device, which can ensure the reliability of target signal or control signaling transmission.

[0085] The switching method and device provided in this application are described in detail below with reference to the accompanying drawings.

[0086] Figure 1 shows a flow chart of an OAM mode indication method according to an embodiment of the present disclosure. As shown in Figure 1 , the method is applied to a first device, which may be but is not limited to a base station, and includes the following steps.

[0087] Step 101: Receive first indication information reported by a second device.

[0088] In the embodiment of the present disclosure, the second device may be a terminal communicating with the first device, or may be a relay device communicating with the first device, and the specific embodiment of the present disclosure does not limit this.

[0089] In the embodiments of the present disclosure, in an OAM communication system, OAM beams are orthogonal to each other. Theoretically, there are an infinite number of OAM modes, each capable of signal transmission. After receiving the first indication information, the first device selects an OAM mode as the target OAM mode for transmitting the target signal or control signaling based on the first indication information.

[0090] It should be noted that the target OAM mode selected based on the first indication information can be the OAM mode with the best transmission quality among all OAM modes, the OAM mode with the second-best transmission quality, or other available OAM modes. Because the target signal and control signaling have high or extremely high reliability requirements for the transmission channel, when selecting the target OAM mode, the OAM mode with the best transmission quality among the available OAM modes is generally preferred. Specific embodiments of the present disclosure do not limit this. It is sufficient that the target OAM mode is not occupied by other signals and can transmit the target signal or control signaling.

[0091] In an OAM communication system, each OAM mode has different transmission quality. The transmission quality of each OAM mode can be determined by measuring the signal under the OAM mode. The higher the measured value, the higher the transmission quality of the OAM mode.

[0092] In addition, it should be noted that in the OAM communication system, the OAM mode can also set a corresponding antenna port, and the transmission quality of the OAM mode can also be obtained by measuring the measurement value of the antenna port corresponding to the OAM mode. The measurement value of the antenna port corresponding to the OAM mode corresponds to the transmission quality of the OAM mode.

[0093] The embodiments of the present disclosure do not limit the specific method for obtaining the transmission quality of different OAM modes.

[0094] In some embodiments of the present disclosure, the first indication information may be any of the following:

[0095] First OAM modal information;

[0096] Measurement values ​​of OAM modes;

[0097] Antenna port information corresponding to the first OAM mode;

[0098] The measured value of the antenna port corresponding to the OAM mode;

[0099] The first OAM mode is an OAM mode with the best transmission quality among available OAM modes determined by the second device according to the OAM mode measurement value.

[0100] When reporting the indication information, the second device may adopt, but is not limited to, the following method, which includes:

[0101] When the second device measures the transmission signal under each OAM mode and obtains the measurement value of each OAM mode, the obtained measurement value of each OAM mode can be directly reported to the first device. Alternatively, the measurement value of each OAM mode can be processed locally on the second device, and the OAM mode with the highest available OAM mode measurement value is selected as the first OAM mode. The first OAM mode has the highest measurement value and is the OAM mode with the best transmission quality among the available OAM modes. The selected first OAM mode is reported to the first device.

[0102] When each OAM mode is provided with a corresponding antenna port, the second device may also measure the transmission signal of the antenna port corresponding to the OAM mode to obtain the measurement value of the antenna port corresponding to each OAM mode; after obtaining the measurement value of the antenna port corresponding to each OAM mode, the second device may directly report the measurement value of the antenna port corresponding to each OAM mode to the first device; or the measurement value of the antenna port corresponding to the OAM mode may be processed locally on the second device to select the antenna port with the highest measurement value among the available OAM modes. There is a mapping relationship between antenna ports and OAM modes. The antenna port has the highest measurement value, indicating that among the available antenna ports, the selected antenna port has the best transmission quality, and the transmission quality of the OAM mode corresponding to the selected antenna port is also the best. The second device uses the OAM mode corresponding to the antenna port with the highest measurement value as the first OAM mode. When reporting, the second device can directly report the first OAM mode to the first device, or report the antenna port information corresponding to the first OAM mode to the first device. The specific embodiments of the present disclosure are not limited to this.

[0103] Step 102: Select an OAM mode as a target OAM mode for transmitting a target signal or control signaling according to the first indication information.

[0104] In an embodiment of the present disclosure, when selecting an OAM mode as the target OAM mode for transmitting a target signal or control signaling according to the first indication information, the OAM mode with the best transmission quality among the available OAM modes is preferentially selected. This can be implemented by, but is not limited to, the following method, which includes:

[0105] In response to the first indication information being first OAM mode information, since the first OAM mode is the OAM mode corresponding to the maximum measurement value among the available OAM modes selected locally by the second device from the OAM mode measurement value or the measurement value of the antenna port corresponding to the OAM mode, upon receiving the first OAM mode information, the first device can directly use the first OAM mode corresponding to the first OAM mode information as the target OAM mode for transmitting the target signal or control signaling, that is, use the first OAM mode as the OAM mode with the best transmission quality among the available OAM modes for transmitting the target signal or control signaling.

[0106] In response to the first indication information being a measurement value of an OAM mode, the OAM mode corresponding to the maximum measurement value among the available OAM modes is selected as the target OAM mode for transmitting the target signal or control signaling, that is, the OAM mode corresponding to the maximum measurement value among the available OAM modes is selected as the OAM mode with the best transmission quality among the available OAM modes, for transmitting the target signal or control signaling.

[0107] In response to the first indication information being antenna port information corresponding to the first OAM mode, receiving the antenna port information indicates that the OAM mode mapping has a corresponding antenna port, and there is a mapping relationship between the antenna port and the OAM mode. Upon knowing the antenna port information, the corresponding first OAM mode can be obtained according to the antenna port information and the mapping relationship between the antenna port and the OAM mode. The first OAM mode is used as the target OAM mode for transmitting the target signal or control signaling, that is, the first OAM mode is used as the OAM mode with the best transmission quality among the available OAM modes for transmitting the target signal or control signaling.

[0108] In response to the first indication information being a measurement value of the antenna port corresponding to the OAM mode, the antenna port corresponding to the maximum measurement value of the antenna port corresponding to the available OAM modes is selected; the OAM mode corresponding to the selected antenna port is determined based on the selected antenna port and a mapping relationship between the antenna port and the OAM mode, and the OAM mode corresponding to the selected antenna port is used as the target OAM mode for transmitting the target signal or control signaling. That is, the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the available OAM modes is used as the OAM mode with the best transmission quality among the available OAM modes, for transmitting the target signal or control signaling.

[0109] In summary, according to the OAM mode indication method provided in the embodiment of the present disclosure, the first device selects an OAM mode as the target OAM mode for transmitting the target signal or control signaling based on the first indication information reported by the second device, and transmits the target signal or control signaling on the selected OAM mode, thereby ensuring the reliability of the target signal or control signaling.

[0110] Figure 2 shows a flow chart of an OAM mode indication method according to an embodiment of the present disclosure. This method is applied to a second device, which can be a terminal or a relay, and is not limited to this embodiment of the present disclosure. Based on the embodiment shown in Figure 1, as shown in Figure 2, the following steps may be included.

[0111] Step 201: Report first indication information to a first device, so that the first device selects an OAM mode as a target OAM mode for transmitting a target signal or control signaling according to the first indication information.

[0112] In an embodiment of the present disclosure, in an OAM communication system, the OAM beams are mutually orthogonal. Theoretically, there are an infinite number of OAM modes, and each OAM mode can transmit signals, but the transmission quality of each OAM mode is different. In order to ensure the reliability of the transmission of the target signal or control signaling, it is necessary to use the OAM mode with the best transmission quality among the available OAM modes to transmit the target signal. The specific method for obtaining the transmission quality of the OAM mode can be, but is not limited to, measuring the measurement signal under each OAM mode, and obtaining the measurement value of the OAM mode transmission quality under each OAM mode by measurement. The measurement value can be measured based on different signals, and the specific embodiment of the present disclosure is not limited to this. After obtaining the measurement value by measuring the measurement signal under each OAM mode, the transmission quality of different OAM modes is obtained based on the measurement value. The higher the measurement value, the higher the transmission quality of the OAM mode.

[0113] It should be noted that in an OAM communication system, an OAM mode can also be assigned a corresponding antenna port. The transmission quality of the OAM mode can also be determined by measuring the value of the antenna port corresponding to the OAM mode. The measured value of the antenna port corresponding to the OAM mode corresponds to the transmission quality of the OAM mode. The higher the measured value of the antenna port, the higher the transmission quality of the antenna port, and the higher the transmission quality of the OAM mode corresponding to the antenna port.

[0114] When reporting the indication information, the second device may adopt, but is not limited to, the following method, which includes:

[0115] When the second device measures the transmission signal under each OAM mode and obtains the measurement value of each OAM mode, the obtained measurement value of each OAM mode can be directly reported to the first device. Alternatively, the measurement value of each OAM mode can be processed locally on the second device, and the OAM mode with the highest available OAM mode measurement value is selected as the first OAM mode. The first OAM mode has the highest measurement value and is the OAM mode with the best transmission quality among the available OAM modes. The selected first OAM mode is reported to the first device.

[0116] When each OAM mode is provided with a corresponding antenna port, the second device may also measure the transmission signal of the antenna port corresponding to the OAM mode to obtain the measurement value of the antenna port corresponding to each OAM mode; after obtaining the measurement value of the antenna port corresponding to each OAM mode, the second device may directly report the measurement value of the antenna port corresponding to each OAM mode to the first device; or the measurement value of the antenna port corresponding to the OAM mode may be processed locally on the second device to select the antenna port with the highest measurement value among the available OAM modes. There is a mapping relationship between antenna ports and OAM modes. The antenna port has the highest measurement value, indicating that among the available antenna ports, the selected antenna port has the best transmission quality, and the transmission quality of the OAM mode corresponding to the selected antenna port is also the best. The second device uses the OAM mode corresponding to the antenna port with the highest measurement value as the first OAM mode. When reporting, the second device can directly report the first OAM mode to the first device, or report the antenna port information corresponding to the first OAM mode to the first device. The specific embodiments of the present disclosure are not limited to this.

[0117] Since the OAM mode transmission quality can be obtained in the above manner, and there is a mapping relationship between the OAM mode and the antenna, when the second device reports the first indication information, the first indication information may be any of the following:

[0118] First OAM modal information;

[0119] Measurement values ​​of OAM modes;

[0120] Antenna port information corresponding to the first OAM mode;

[0121] The measured value of the antenna port corresponding to the OAM mode;

[0122] The first OAM mode is an OAM mode with the best transmission quality among available OAM modes determined by the second device according to the OAM mode measurement value.

[0123] In summary, according to the OAM mode indication method provided by the embodiment of the present disclosure, after the second device obtains information related to the OAM mode transmission quality, it reports to the first device indication information of a target OAM mode reference for the first device to select an OAM mode for transmitting a target signal or control signaling. In response to the first indication information, the first device selects a target OAM mode for transmitting the target signal or control signaling in an OAM mode, and transmits the target signal or control signaling on the selected OAM mode, thereby ensuring the reliability of the target signal or control signaling.

[0124] In some embodiments of the present disclosure, the measured value of the OAM mode may be, but is not limited to, any of the following:

[0125] Signal to Interference plus Noise Ratio (SINR) measurement value, Reference Signal Receiving Power (RSRP) measurement value, Reference Signal Receiving Quality (RSRQ) measurement value, Received Signal Strength Indicator (RSSI) measurement value.

[0126] In some embodiments of the present disclosure, the target signal or control signaling includes: Phase Tracking Reference Signal (PT-RS), Radio Resource Control (RRC) signaling, enhanced Media Access Control Command Element (MAC Control Element, MAC CE), and physical layer control information.

[0127] In some embodiments of the present disclosure, after obtaining the measurement value of each OAM mode, the second device may perform local processing to select the optimal OAM mode from the available OAM modes. After selecting the optimal OAM mode from the available OAM modes, i.e., the first OAM mode, the first mode is reported to the first device. Alternatively, the second device may directly report the obtained measurement value of each OAM mode to the first device without performing local processing. The embodiments of the present invention do not limit the specific method used by the second device to report the first indication information for selecting an OAM mode as the transmission target signal or control signaling to the first device. When the second device performs local processing to select the first OAM mode, it may be implemented by, but is not limited to, the following method: the second device selects the OAM mode corresponding to the maximum measurement value from the available OAM modes as the first OAM mode from the measurement values, and reports the first OAM mode to the first device.

[0128] In some embodiments of the present disclosure, the second device selects, from the measured values, an OAM mode corresponding to a maximum measured value among the available OAM modes as the first OAM mode, which may be implemented by, but not limited to, the following method, including:

[0129] When the measured value of the OAM mode is an SINR measured value, in response to the measured value of the OAM mode being the SINR measured value, an OAM mode corresponding to a maximum SINR measured value among available OAM modes is selected from the measured values ​​of the OAM modes as the first OAM mode.

[0130] When the measurement value of the OAM mode is an RSRP measurement value, in response to the measurement value of the OAM mode being the RSRP measurement value, the second device selects an OAM mode corresponding to a maximum RSRP measurement value in available OAM modes from the measurement values ​​of the OAM modes as the first OAM mode, and reports the first OAM mode to the first device.

[0131] When the measurement value of the OAM mode is an RSRQ measurement value, in response to the measurement value of the OAM mode being the RSRQ measurement value, the second device selects an OAM mode corresponding to a maximum RSRQ measurement value among available modes from the measurement values ​​of the OAM modes as the first OAM mode, and reports the first OAM mode to the first device.

[0132] When the measurement value of the OAM mode is an RSSI measurement value, in response to the measurement value of the OAM mode being the RSSI measurement value, the second device selects an OAM mode corresponding to a maximum RSSI measurement value in available OAM modes from the measurement values ​​of the OAM modes as the first OAM mode, and reports the first OAM mode to the first device.

[0133] Based on the first indication information reported by the above-mentioned second device, when the first indication information received by the first device is the measurement value of the OAM mode, the measurement value of the OAM mode can be but is not limited to any one of the following information, including: SINR measurement value, RSRP measurement value, RSRQ measurement value, RSSI measurement value.

[0134] In some embodiments of the present disclosure, the first device selects an OAM target mode for target signal transmission based on the measured value of the OAM mode. Specifically, but not limited to, the following method can be adopted: the OAM mode corresponding to the maximum measured value among the available OAM modes is selected from the measured values ​​of the OAM modes as the target OAM mode.

[0135] In some embodiments of the present disclosure, when the first device selects the OAM mode corresponding to the maximum measured value among the available OAM modes from the measured values ​​of the OAM modes as the target OAM mode, this can be achieved by, but is not limited to, the following method, which includes:

[0136] When the measurement value of the OAM mode in the first indication information received by the first device is an SINR test value, in response to the measurement value, the first device selects, from the measurement values, an OAM mode corresponding to a maximum SINR measurement value in available OAM modes as the target OAM mode.

[0137] When the measurement value of the OAM mode in the first indication information received by the first device is an RSRP measurement value, in response to the measurement value, an OAM mode corresponding to a maximum RSRP measurement value in available OAM modes is selected from the measurement values ​​as the target OAM mode.

[0138] When the measurement value of the OAM mode in the first indication information received by the first device is an RSRQ measurement value, in response to the measurement value being the RSRQ measurement value, an OAM mode corresponding to a maximum RSRQ measurement value among available OAM modes is selected from the measurement values ​​as the target OAM mode.

[0139] When the measurement value of the OAM mode in the first indication information received by the first device is an RSSI measurement value, in response to the measurement value, the OAM mode corresponding to the maximum RSSI measurement value in the available OAM modes is selected from the measurement values ​​as the target OAM mode.

[0140] In some embodiments of the present disclosure, when a mapping relationship exists between an OAM mode and an antenna port, as described above, the second device can obtain the measurement value of the antenna port corresponding to the OAM mode. After obtaining the measurement value of each OAM mode, the second device can process it locally and select the optimal OAM mode from the available OAM modes based on the measurement value of the antenna port corresponding to the OAM mode. After selecting the optimal OAM mode from the available OAM modes, that is, the first OAM mode, the first mode is reported to the first device. Alternatively, the second device can directly report the measurement value of the antenna port corresponding to each OAM mode obtained to the first device without performing local processing. The specific method used by the second device to report the first indication information for selecting an OAM mode as the transmission target signal or control signaling to the first device is not limited in this embodiment of the present invention. When the second device uses local processing to select the first OAM mode, it can be implemented by, but is not limited to, the following method: the second device selects, from the measurement values ​​of the antenna ports corresponding to the OAM modes, the OAM mode corresponding to the maximum measurement value of the antenna ports corresponding to the available OAM modes as the first OAM mode, and reports the first OAM mode to the first device.

[0141] In some embodiments of the present disclosure, the measurement value of the antenna port corresponding to the OAM mode may be any one of the following, including: an SINR measurement value, an RSRP measurement value, an RSRQ measurement value, and an RSSI measurement value.

[0142] Among them, the second device selects, from the measurement values ​​of the antenna port corresponding to the OAM mode, the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the available OAM mode as the relevant description of the first OAM mode, which can refer to the second device selecting the OAM mode corresponding to the maximum measurement value of the available OAM modes from the measurement values ​​as the first OAM mode. It can be implemented by but not limited to the following methods, including:

[0143] When the measurement value of the antenna port corresponding to the OAM mode is an SINR measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the SINR measurement value, the second device selects the OAM mode corresponding to the maximum SINR measurement value in the available OAM modes from the measurement values ​​of the antenna port corresponding to the OAM mode as the first OAM mode.

[0144] When the measurement value of the antenna port corresponding to the OAM mode is an RSRP measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the RSRP measurement value, the second device selects the OAM mode corresponding to the maximum RSRP measurement value in the available OAM modes from the antenna port measurement values ​​corresponding to the OAM mode as the first OAM mode.

[0145] When the measurement value of the antenna port corresponding to the OAM mode is an RSRQ measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the RSRQ measurement value, the second device selects the OAM mode corresponding to the maximum RSRQ measurement value in the available modes from the antenna port measurement values ​​corresponding to the OAM mode as the first OAM mode.

[0146] When the antenna port measurement value corresponding to the OAM mode is an RSSI measurement value, in response to the antenna port measurement value corresponding to the OAM mode being the RSSI measurement value, the second device selects an OAM mode corresponding to a maximum RSSI measurement value among available OAM modes from the antenna port measurement values ​​corresponding to the OAM mode as the first OAM mode, and reports the first OAM mode to the first device, so that when the first device receives the first OAM mode, it selects the first OAM mode as the target OAM mode for performing target signaling or control signaling.

[0147] In some embodiments of the present disclosure, when the indication information received by the first device is the antenna port information corresponding to the first OAM mode, the first device obtains a mapping relationship between the OAM mode and the antenna port in response to the antenna port information corresponding to the first OAM mode, and obtains the first OAM mode corresponding to the antenna port based on the mapping relationship. Furthermore, the first device maintains or adjusts the mapping relationship between the OAM mode and the antenna port so that the target OAM mode is mapped to the target antenna port.

[0148] When the first device receives the first indication information including the measurement value of the antenna port corresponding to the OAM mode, it can be implemented using but not limited to the following method: the second device selects the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the available OAM mode from the measurement values ​​of the antenna port corresponding to the OAM mode as the target OAM mode.

[0149] When the measurement value of the antenna port corresponding to the OAM mode in the first indication information is an SINR measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the SINR measurement value, the first device selects the OAM mode corresponding to the maximum SINR measurement value in the available OAM modes from the measurement values ​​of the antenna port corresponding to the OAM mode as the target OAM mode.

[0150] When the measurement value of the antenna port corresponding to the OAM mode in the first indication information is an RSRP measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the RSRP measurement value, the second device selects the OAM mode corresponding to the maximum RSRP measurement value in the available OAM modes from the antenna port measurement values ​​corresponding to the OAM modes as the target OAM mode.

[0151] When the measurement value of the antenna port corresponding to the OAM mode corresponding to the OAM mode in the first indication information is an RSRQ measurement value, in response to the measurement value of the antenna port corresponding to the OAM mode being the RSRQ measurement value, the first device selects the OAM mode corresponding to the maximum RSRQ measurement value in the available modes from the antenna port measurement values ​​corresponding to the OAM mode as the target OAM mode.

[0152] Figure 3 shows a flow chart of an OAM mode indication method according to an embodiment of the present disclosure. The method is applied to a first device, based on the embodiment shown in Figure 1, as shown in Figure 3, and may include the following steps.

[0153] Step 301: Determine the target signal or control signaling carried by the target OAM mode.

[0154] The transmission of some target signals or control signaling in a mobile communication system requires extremely high reliability, which requires that these target signals or control signaling need to be transmitted in some channels with higher transmission quality. For example, the target signal or control signaling may include but is not limited to: PT-RS, RRC signaling, MAC CE, physical layer control information, etc., and may also be other signals or control signaling. In the embodiments of the present disclosure, it is necessary to determine which target signals or control signaling are transmitted in a determined target OAM mode. When determining the target signal or control signaling, it may be implemented in the following manner but is not limited to: the target signal or control signaling carried by the target OAM mode may be determined by the first device, or the target signal or control signaling carried by the target OAM mode may be determined according to a predetermined protocol agreement.

[0155] In summary, according to the OAM mode indication method provided in the embodiments of the present disclosure, a first device selects an OAM mode as the target OAM mode for transmitting a target signal or control signaling based on the first indication information reported by the second device, and transmits the target signal or control signaling on this target OAM mode, thereby ensuring the reliability of the target signal or control signaling transmission. Furthermore, when determining the target signal or control signaling to be transmitted on the target OAM mode, this can be determined based on a protocol or by the first device, providing a flexible implementation method and ensuring that the target signal or control signaling is transmitted on the optimal OAM mode among the available OAM modes.

[0156] Figure 4 shows a flow chart of an OAM mode indication method according to an embodiment of the present disclosure. The method is applied to a first device, based on the embodiment shown in Figure 3, as shown in Figure 4, and may include the following steps.

[0157] Step 401: Determine the target signal or control signaling carried by the target OAM mode.

[0158] In the embodiment of the present disclosure, for the relevant description of determining the target signal or control signaling carried by the target modality, reference may be made to the description of step 301 in FIG. 3 , which will not be repeated here.

[0159] Step 402: The first device instructs the second device to receive a corresponding target signal or control signaling on the target OAM mode.

[0160] When instructing the second device to receive the corresponding target signal on the target OAM mode, the following method may be used but is not limited to:

[0161] Second indication information is sent to the second device, instructing the second device to receive a corresponding target signal or control signaling on the target OAM mode, where the second indication information includes information about the target OAM mode.

[0162] In some embodiments of the present disclosure, when the first device instructs the second device to receive the corresponding target signal or control signaling on the target OAM mode, the method may further include:

[0163] The first device sends second indication information to the second device, instructing the second device to receive a corresponding target signal or control signaling on the target OAM mode. When the first device sends the second indication information to the second network device, a specific description may be provided based on whether the second network device is configured with an antenna port associated with the OAM mode.

[0164] In some embodiments of the present disclosure, when the OAM mode is not set with a corresponding antenna port, when the target signal or control signaling is transmitted through the OAM mode, regardless of which OAM mode the target OAM mode is determined to be, it is necessary to notify the target OAM mode of which OAM mode it is. In this case, the first device sends second indication information to the second device, indicating the target OAM mode for transmitting the target signal or control signaling. Therefore, in response to the fact that the OAM mode is not mapped to a corresponding antenna port, the target OAM mode is indicated to the second device through the second indication information, and the second device is instructed to receive the corresponding target signal or control signaling on the target OAM mode.

[0165] When the OAM mode is not mapped to a corresponding antenna port, indicating the target OAM mode to the second device through the second indication information, and instructing the second device to receive the corresponding target signal or control signaling in the target OAM mode, can be implemented by, but not limited to, the following method, which includes:

[0166] When the determined target OAM mode is the OAM mode or the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the OAM mode, since the second device does not know the target OAM mode, if the second indication information does not include the information of the target OAM mode, the second device will not be able to know which OAM mode to use to receive the target signal or control signaling, so it is necessary to send the information of the selected target OAM mode to the second device; when the target signal or control signaling carried by the target OAM mode is the target signal or control signaling determined according to a predetermined protocol agreement, since the second device can know the target signal or control signaling carried by the target OAM mode according to the predetermined protocol agreement, it is not necessary to send the information of the target signal or control signaling carried by the target OAM mode to the second device; therefore, in response to the target signal or control signaling carried by the target OAM mode being the target signal or control signaling determined according to the predetermined protocol agreement, and the target OAM mode being the OAM mode or the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the OAM mode, second indication information is sent to the second device, and the second indication information includes the target OAM mode information.

[0167] When the determined target OAM mode is the first OAM mode or the antenna port information corresponding to the first OAM mode, although the antenna port associated with the OAM mode is not set in the second device, if the determined target OAM mode is the first OAM mode reported by the second device, the second indication information does not include the information of the target OAM mode. The second device can also know the antenna port corresponding to the target OAM mode, so there is no need to send the information of the determined target OAM mode to the second device; when the target signal or control signaling carried by the target OAM mode is the target signal or control signaling confirmed by the first device, due to The target signal or control signaling is confirmed by the first device, and the second device cannot know it in advance, so it is necessary to send the information of the target signal or control signaling carried by the target OAM mode to the second device; therefore, in response to the target signal or control signaling carried by the target OAM mode being the target signal or control signaling confirmed by the first device according to a predetermined protocol, and the target OAM mode is the first OAM mode or the antenna port information corresponding to the first OAM mode, second indication information is sent to the second device, and the second indication information includes the target signal or control signaling information carried by the target OAM mode.

[0168] When the determined target OAM mode is the OAM mode or the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the OAM mode, since the second device does not know the target OAM mode, if the information of the target OAM mode is not included in the second indication information, the second device will not be able to know which OAM mode to use to receive the target signal or control signaling, so it is necessary to send the information of the selected target OAM mode to the second device; when the target signal or control signaling carried by the target OAM mode is the target signal or control signaling confirmed by the first device, since the target signal or control signaling is confirmed by the first device , if the second device cannot be known in advance, it is necessary to send the target signal or control signaling information carried by the target OAM mode to the second device; therefore, in response to the target signal or control signaling carried by the target OAM mode being the target signal or control signaling confirmed by the first device, and the target OAM mode is the OAM mode or the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the OAM mode, second indication information is sent to the second device, and the second indication information includes the target OAM mode information and the target signal or control signaling information carried by the target OAM mode.

[0169] In some embodiments of the present disclosure, when an OAM mode is provided with a corresponding antenna port, it indicates that no matter which OAM mode the first device selects as the target OAM mode, the target antenna port is used to receive the target signal or control signaling transmitted by the target OAM mode, and the first device does not need to notify the second device which OAM mode the target OAM mode is. In this case, it is only necessary to send the target signal or control signaling information carried by the determined target OAM mode to the second device. When the second device is provided with an antenna port associated with the OAM mode, sending the second indication information to the second device can be implemented by, but not limited to, the following method, which includes:

[0170] In response to the target signal or control signaling carried by the target OAM mode being the target signal or control signaling confirmed by the first device, and the target OAM mode being the OAM mode or the OAM mode corresponding to the maximum measurement value of the antenna port corresponding to the OAM mode, second indication information is sent to the second device, where the second indication information includes the target signal or control signaling information carried by the target OAM mode.

[0171] Among them, the relevant description about the target signal or control signaling information can refer to the corresponding description above and will not be repeated here.

[0172] In some embodiments of the present disclosure, in addition to instructing the second device to receive the corresponding target signal or control signaling on the target OAM mode through instructions, the second device may also receive the corresponding target signal or control signaling on the target OAM mode through a protocol agreement. When the second device receives the corresponding target signal on the target OAM mode through a protocol agreement, this may be achieved in the following ways, including but not limited to:

[0173] When an OAM mode is assigned a corresponding antenna port, regardless of which OAM mode the first device selects as the target OAM mode, the target antenna port is used to receive the target signal or control signaling transmitted in the target OAM mode. The first device does not need to notify the second device of the target OAM mode. Therefore, in response to the OAM mode being mapped to a corresponding antenna port, the second device receives the corresponding target signal or control signaling on the target antenna port.

[0174] In some embodiments of the present disclosure, when the target signal or control signaling carried by the target OAM mode is determined according to a predetermined protocol, the first device and the second device learn the target signal or control signaling carried by the target OAM mode according to the predetermined protocol, without the first device sending indication information of the target signal or control signaling carried by the target OAM mode to the second device. Furthermore, based on the configuration of a corresponding antenna port for the OAM mode, the second device receives the indication information of the corresponding target signal or control signaling agreed upon in the protocol on the target antenna port.

[0175] In a specific implementation, when the OAM mode mapping has a corresponding antenna port, the mapping relationship between the OAM mode and the antenna port is maintained or adjusted so that the target OAM mode is mapped to the target antenna port, and the target antenna port receives the corresponding target signal or control signaling.

[0176] In some embodiments of the present disclosure, although the OAM mode does not have a corresponding antenna port, when the selected target OAM mode is the first OAM mode reported by the second device, even if the selected target OAM mode for transmitting the target signal or control signaling is not indicated to the second device, the second device can also know that the target OAM mode for transmitting the target signal or control signaling is the first OAM mode; therefore, in response to the OAM mode not having a corresponding antenna port, the target OAM mode being the first OAM mode, and the target signal or control signaling carried by the target OAM mode being the target signal or control signaling determined according to a predetermined protocol agreement, the second device receives the corresponding target signal or control signaling agreed upon in the agreed first OAM mode.

[0177] In addition to the above two cases, the second device may receive the corresponding target signal or control signaling on the target OAM mode based on the protocol agreement. In other cases, the second device may receive the corresponding target signal or control signaling on the target OAM mode through the protocol agreement. The specific embodiments of the present disclosure are not limited to this, and the specific embodiments may be implemented according to actual conditions.

[0178] In summary, according to the OAM mode indication method provided in the embodiments of the present disclosure, a first device selects an OAM mode as the target OAM mode for transmitting a target signal or control signaling based on the first indication information reported by the second device, and transmits the target signal or control signaling on this target OAM mode, thereby ensuring the reliability of the target signal or control signaling transmission. Furthermore, when determining the target signal or control signaling to be transmitted on the target OAM mode, this can be determined based on a protocol or by the first device, providing a flexible implementation method and ensuring that the target signal or control signaling is transmitted on the optimal OAM mode among the available OAM modes.

[0179] In some embodiments of the present disclosure, based on the first device sending second indication information to the second device, as shown in FIG5 , the method includes:

[0180] 501. Receive a corresponding target signal or control signaling in the target OAM mode according to the target signal or control signaling reception indication information of the first device.

[0181] In some embodiments of the present disclosure, receiving the corresponding target signal or control signaling on the target OAM mode according to the target signal or control signaling reception indication information of the first device may be implemented by, but not limited to, the following method, which includes:

[0182] Receive second indication information sent by the first device, and in response to the second indication information, receive a corresponding target signal or control signaling on a target OAM mode indicated by the second indication information.

[0183] In some embodiments of the present disclosure, a second device receives second indication information sent by the first device, and in response to the second indication information, receives a corresponding target signal or control signaling on a target OAM mode indicated by the second indication information. Receiving the corresponding target signal or control signaling on the target OAM mode according to the second indication information by the second device may be implemented using, but is not limited to, the following method, including:

[0184] When the second indication information includes only target OAM modal information, it indicates that the target signal or control signaling carried by the target OAM modal is determined according to a predetermined protocol. In response to the target OAM modal information being included in the second indication information, the target signal or control signaling agreed upon in the predetermined protocol is received on the target OAM modal corresponding to the target OAM modal information.

[0185] When the second indication information includes only the target signal or control signaling information carried by the target OAM mode, it indicates that the OAM mode is set with a corresponding antenna port or the target OAM mode is the first OAM mode reported by the second device, and the target signal or control signaling carried by the target OAM mode is determined by the first device. In response to the target signal or control signaling information carried by the target OAM mode being included in the second indication information, the target signal or control signaling corresponding to the target signal or control signaling information carried by the target OAM mode is received at the target antenna port or the first OAM mode.

[0186] In response to the second indication information including the target OAM modal information and the target signal or control signaling information carried by the target OAM modal, a target signal or control signaling corresponding to the target signal or control signaling information carried by the target OAM modal is received on the target OAM modal corresponding to the target OAM modal information.

[0187] In some embodiments of the present disclosure, a corresponding target signal or control signaling may be received on a target OAM mode according to a protocol agreement. In response to a protocol agreement indication, when receiving a corresponding target signal or control signaling on a target OAM mode according to a protocol agreement, the following method may be used, but is not limited to, to implement the method, including:

[0188] When the OAM mode is set with a corresponding antenna port, regardless of the target OAM mode selected by the first device, the corresponding target signal or control signaling is received at the target antenna port. Therefore, in response to the OAM mode being set with a corresponding antenna port and the target signal or control signaling carried by the target OAM mode being the target signal or control signaling agreed upon in a predetermined protocol, the target signal or control signaling agreed upon in the protocol is received on the target antenna port in accordance with the protocol.

[0189] When the OAM mode is not set with a corresponding antenna port, but the target OAM mode selected by the first device is the first OAM mode reported by the second device, although the second indication information does not include information about the target OAM mode, the second device can also learn that the target OAM mode is the first OAM mode reported by it according to the protocol agreement. Therefore, in response to the fact that the OAM mode is not set with a corresponding antenna port, the target OAM mode is the first OAM mode, and the target signal or control signaling specified in the protocol is received on the target antenna port according to the protocol agreement.

[0190] In summary, according to the OAM mode indication method provided in the embodiments of the present disclosure, a first device selects an OAM mode as the target OAM mode for transmitting a target signal or control signaling based on the first indication information reported by the second device, and transmits the target signal or control signaling on this target OAM mode, thereby ensuring the reliability of the target signal or control signaling transmission. Furthermore, when determining the target signal or control signaling to be transmitted on the target OAM mode, this can be determined based on a protocol or by the first device, providing a flexible implementation method and ensuring that the target signal or control signaling is transmitted on the optimal OAM mode among the available OAM modes.
