[0039] 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.

[0040] The real-world application scenarios of mobile network communication technology are constantly expanding. Future-oriented applications such as augmented reality (AR), virtual reality (VR), and new internet applications (such as the Internet of Vehicles and the Internet of Things) are emerging. These applications are placing increasing demands on network communication speed, latency, bandwidth, and other capabilities. To meet these demands, more and more high-frequency bands, such as millimeter waves and terahertz bands, are being developed. However, spectrum, a finite resource, is becoming increasingly scarce. Therefore, in addition to developing higher frequency bands, seeking communication technologies with higher spectral efficiency has become a top priority.

[0041] With the emergence of the concept of vortex electromagnetic waves, linking them to orbital angular momentum (OAM) has greatly expanded the limitations of the modulation dimension in traditional technologies. Currently, there are two main approaches to transmitting information using OAM: OAM-Shift Keying (OAM-SK) and OAM-Division Multiplexing (OAM-DM). For either approach, the OAM modes carried by vortex electromagnetic waves are theoretically infinite in number, and OAM beams with different integer eigenvalues ​​are mutually orthogonal, theoretically increasing spectrum utilization infinitely. In other words, the electromagnetic beam carrying OAM has an infinite number of modes, and each mode is mutually orthogonal. This makes OAM communication characterized by simple generation and demodulation methods, the absence of complex receiving and demodulation algorithms, infinite modes, and ultra-high spectral efficiency. Therefore, mode division multiplexing can be implemented to improve spectrum efficiency and channel capacity to solve the problem of low detection efficiency of the detection system.

[0042] A typical application is OAM communication based on a uniform circular array (UCA). In this system, uplink transmission requires the transmission of an uplink reference signal. This signal is used to obtain uplink channel information, ensure channel reciprocity, and achieve downlink channel acquisition and uplink beam management. However, related technologies all rely on multiple-input, multiple-output (MIMO) arrays for transmission configuration, and uplink transmission configuration has not yet been addressed in OAM-based communications.

[0043] To this end, the present disclosure proposes an uplink transmission configuration method, device and system based on orbital angular momentum, which can effectively solve the resource configuration of reference signals and the mapping between antenna ports and OAM modes during uplink channel transmission.

[0044] It can be understood that the solution provided in the present disclosure can be used for the fifth generation mobile communication technology (Fifth Generation, 5G) and its subsequent communication technologies, such as the fifth generation mobile communication technology evolution (5G-advanced), the sixth generation mobile communication technology (Sixth Generation, 6G), etc., and is not limited in the present disclosure.

[0045] The following is a detailed introduction to the uplink transmission configuration solution based on orbital angular momentum provided by this application in conjunction with the accompanying drawings.

[0046] Figure 1 shows a flow chart of a method for configuring uplink transmission based on orbital angular momentum according to an embodiment of the present disclosure. As shown in Figure 1 , the method is performed by a first device. In the embodiment of the present disclosure, the first device is a network device, specifically a base station.

[0047] The method may include the following steps.

[0048] S101: Determine configuration information of an uplink sounding reference signal of the second device according to capability information of the second device.

[0049] In an embodiment of the present disclosure, the second device may be a network device, such as a relay or a smart repeater, including but not limited to a network-controlled repeater (NCR).

[0050] In the embodiment of the present disclosure, the second device may also be a user equipment (UE), including but not limited to an intelligent terminal device, a cellular phone, a wireless device, a handset, a mobile unit, a vehicle, a vehicle-mounted device, etc.

[0051] In the present disclosure, the configuration information of the uplink measurement reference signal of the second device includes at least one of the following: an OAM modal value of the uplink measurement reference signal; and an antenna port corresponding to the OAM modal value.

[0052] It is understood that in the present disclosure, the configuration of the uplink measurement reference signal between the first device and the second device may include two methods: In the first method, there is an association or binding relationship between the OAM modal value and the antenna port, and this association or binding relationship is agreed upon or configured in advance. In this case, the configuration information of the uplink measurement reference signal may include only one of the OAM modal value and the antenna port; In the second method, the OAM modal value and the antenna port are not bound in advance, and the configuration information of the uplink measurement reference signal includes the OAM modal value and the antenna port. It should be noted that there is a one-to-one correspondence between the antenna port and the OAM modal value.

[0053] S102: Send configuration information of an uplink sounding reference signal to a second device.

[0054] In an embodiment of the present disclosure, the first device may send the determined configuration information of the uplink sounding reference signal to the second device to assist the second device in generating a transmission beam of the uplink sounding reference signal and thereby sending the uplink sounding reference signal.

[0055] In summary, according to the uplink transmission configuration method based on orbital angular momentum provided by the embodiment of the present disclosure, the first device can determine the configuration information of the uplink measurement reference signal of the second device based on the capability information of the second device, wherein the configuration information includes at least one of the following: the OAM mode value of the uplink measurement reference signal; the antenna port corresponding to the OAM mode value, and the configuration information of the uplink measurement reference signal is sent to the second device, providing an uplink transmission configuration scheme suitable for OAM communication scenarios, which effectively solves the resource configuration and mapping problems of uplink transmission.

[0056] Figure 2 shows a flow chart of a method for configuring uplink transmission based on orbital angular momentum 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 2, and may include the following steps.

[0057] S201: Receive an uplink sounding reference signal sent by a second device.

[0058] In an embodiment of the present disclosure, the first device may receive an uplink sounding reference signal sent by the second device and perform subsequent processing.

[0059] S202: Measure an uplink sounding reference signal sent by a second device.

[0060] In an optional embodiment, the uplink sounding reference signal may be generated by the second device according to the configuration information of the uplink sounding reference signal. In an optional embodiment, the configuration information of the uplink sounding reference signal may be obtained by configuration of the first device.

[0061] For example, the first device can measure the uplink measurement reference signal sent by the second device to obtain a measurement result, and determine the configuration information of the uplink data channel and the demodulation reference signal of the second device according to the measurement result.

[0062] Specifically, in an embodiment of the present disclosure, the first device receives an uplink measurement reference signal sent by the second device, and calculates channel information of the uplink measurement reference signal as a measurement result. The channel information can characterize the quality of the uplink measurement reference signal, including but not limited to at least one of signal to interference plus noise ratio (SINR), reference signal received power (RSRP), reference signal received quality (RSRQ), and received signal strength indication (RSSI), or any other parameter that can measure signal quality, which is not limited in the present disclosure.

[0063] S203: Determine configuration information of an uplink data channel and a demodulation reference signal of the second device according to the measurement result.

[0064] In an embodiment of the present disclosure, the first device may determine the configuration information of the uplink data channel and the demodulation reference signal of the second device according to a measurement result obtained by measuring the uplink sounding reference signal.

[0065] In a specific implementation, the first device may use the configuration information corresponding to the uplink sounding reference signal whose measurement result meets the communication condition as the configuration information of the uplink data channel and its demodulation reference signal of the second device.

[0066] For example, the first device may perform screening based on the principle of maximizing channel capacity, or select the antenna port and / or OAM mode corresponding to the uplink measurement reference signal with a better measurement result as the configuration information of the uplink data channel and its demodulation reference signal of the second device. The specific manner in which the first device determines the configuration information of the uplink data channel and its demodulation reference signal of the second device based on the measurement result is not limited in this disclosure.

[0067] S204: Send configuration information of the uplink data channel and the demodulation reference signal of the second device to the second device.

[0068] In the present disclosure, the first device sends the determined configuration information of the uplink data channel and demodulation reference signal of the second device to the second device, so that the second device can perform uplink transmission of signals or data according to the configuration information, thereby completing the uplink transmission configuration in the OAM communication system.

[0069] In summary, according to the orbital angular momentum-based uplink transmission configuration method disclosed in the present invention, the first device can receive the uplink measurement reference signal sent by the second device, measure the uplink measurement reference signal, determine the configuration information of the uplink data channel and its demodulation reference signal based on the measurement result, and send it to the second device, thereby completing the uplink transmission configuration suitable for OAM communication scenarios, effectively solving the resource configuration and mapping problems of uplink transmission, and providing optional solutions to enhance applicability.

[0070] Figure 3 shows a flow chart of a method for configuring uplink transmission based on orbital angular momentum according to an embodiment of the present disclosure. The method is applied to a first device, based on the embodiments shown in Figures 1 and 2, as shown in Figure 3, and may include the following steps.

[0071] S301: Receive capability information of a second device.

[0072] In an embodiment of the present disclosure, the capability information includes the maximum number of transmit OAM modes supported by the second device and / or identifiers of each OAM mode.

[0073] It is understood that the maximum number of transmit OAM modes supported by the second device is related to the hardware configuration of the second device, specifically, the number of antenna elements of the second device. For example, assuming that the second device is configured with 8 antenna elements, the maximum number of transmit OAM modes supported by the second device is 8.

[0074] In addition, the capability information of the second device may also include identifiers of each modality supported by the second device, for example, each modality may be numbered with an integer. In the above example, the eight OAM modalities may be numbered with integers from 1 to 8. The identifier uniquely identifies the OAM mode, and the size or order of the identifier does not impose any restrictions on the modalities themselves.

[0075] S302: Determine configuration information of an uplink sounding reference signal of the second device according to capability information of the second device.

[0076] In an embodiment of the present disclosure, the first device may determine the configuration information of the uplink measurement signal of the second device according to the received capability information of the second device.

[0077] For example, after receiving the capability information, the first device may configure the configuration information of the uplink sounding reference signal according to the currently schedulable modes. The first device may also configure according to the current communication environment state under each mode, which is not limited in this disclosure.

[0078] In an embodiment of the present disclosure, the OAM modal value of the uplink sounding reference signal is: an identifier of an OAM mode, the identifier being obtained from capability information of the second device; and / or an index of a modality set formed by two or more OAM modes.

[0079] In other words, the first device can configure the uplink measurement reference signal in multiple forms. The first device can directly select the identifier of a certain OAM mode as the OAM mode value, or it can form a set of multiple OAM modes, configure an index for the set, and use the index as the mode value of the mode set. The multiple OAM modes contained in the set still correspond to their own identifiers. For example, the second device reports the capability information of 8 OAM modes. The first device determines that the schedulable OAM modes include 6 modes identified as 1-6, and configures the uplink measurement reference signal, such as configuring the OAM modes identified as 1-3 and forming a mode set with the modes identified as 4-6 and configuring the index as 001.

[0080] In some optional embodiments, the configuration information of the uplink sounding reference signal may further include time-frequency resource information and a sending mode of the uplink sounding reference signal.

[0081] Among them, the time-frequency resource information includes the time domain position and the frequency domain position. The time domain position indicates the time when the signal is sent, which can be indicated by, for example, the sending period, the offset position within the period, and the indicated time unit can be a time slot or an OFDM symbol, etc. The frequency domain position indicates the resource block (RB) where the antenna port is located or the subcarrier set where it is located.

[0082] The sending mode includes a periodic sending mode, a semi-periodic sending mode, or a non-periodic sending mode, wherein the periodic sending mode is that the second device sends at a preset period, that is, the second device periodically sends signals according to the specified parameters; the semi-periodic sending mode is that the second device sends at a preset period after receiving the activation signaling sent by the first device, that is, the second device periodically sends signals only after receiving the activation signaling about the semi-periodic uplink reference signal resource, and adds a trigger condition on the basis of periodic sending; the non-periodic sending mode is that the second device sends once in response to the activation signaling sent by the first device, that is, the second device only sends once in response to the uplink reference signal activation signaling, and does not send at other times.

[0083] In this disclosure, the transmission mode to be used depends on the specific needs of uplink transmission. For example, when uplink transmission is frequent, uplink sounding reference signal transmission is also frequent, so a periodic transmission mode can be used. If uplink transmission tasks are less frequent, periodic transmission will waste transmission resources, so a semi-periodic or aperiodic transmission mode can be used. The period value in the above-mentioned periodic and semi-periodic transmission modes depends on the frame structure and is not specifically limited in this disclosure.

[0084] It is worth noting that, in the present disclosure, the above-mentioned time-frequency resource information and the sending method are configured by the first device or determined according to the communication protocol between the first device and the second device.

[0085] Specifically, the time-frequency resource information and sending method of the uplink measurement reference signal can be configured by the first device. The first device can configure the time-frequency resource information and sending method of the uplink measurement reference signal by considering the busyness of the time, interference factors or the transmission needs described above, so it is more flexible.

[0086] In an optional embodiment, the time-frequency resource information and the sending method of the uplink measurement reference signal can also be agreed upon through a protocol between the first device and the second device. For example, by agreeing on the time-frequency pattern and the sending method of the uplink reference signal antenna port, the first device does not need to perform further configuration or subsequent signaling interaction, thereby saving the processing capability of the first device and simplifying the communication process.

[0087] S303: Send configuration information of an uplink sounding reference signal to the second device.

[0088] In the present disclosure, the configuration information of the uplink sounding reference signal is used to assist the second device in generating a transmission beam of the uplink sounding reference signal to send the uplink sounding reference signal.

[0089] In one embodiment, the first device may notify the second device of the configuration information of the uplink sounding reference signal via signaling, for example, radio resource control (RRC) signaling, media access control (MAC) signaling, or physical layer signaling (e.g., downlink control information (DCI) signaling). The signaling type is not limited in this disclosure. The configuration information includes at least one of the following a) and b):

[0090] a) an OAM mode set (and / or its index) of an uplink measurement reference signal, i.e., an OAM mode value configured by the first device;

[0091] b) an antenna port set (and / or its index) of an uplink measurement reference signal, that is, the antenna port corresponding to the OAM modal value configured by the first device.

[0092] In addition, if the time-frequency resource information and the sending mode of the uplink sounding reference signal are configured by the first device, the configuration information further includes:

[0093] c) The time-frequency position occupied by the uplink measurement reference signal and the transmission method.

[0094] If the time-frequency resource information and the sending mode are agreed upon by a protocol, the configuration information of the uplink sounding reference signal sent by the first device to the second device does not include the above c).

[0095] It can be understood that after receiving the configuration information sent by the first device, the second device can execute which port to send the beam, how much time-frequency resources to occupy, and how to send the beam according to the configuration information. That is, the relay can send the uplink measurement reference signal on the specified time-frequency resources, using the specified antenna port and in the specified sending method.

[0096] S304: Receive an uplink sounding reference signal sent by the second device.

[0097] In an embodiment of the present disclosure, the second device may generate a transmission beam of an uplink sounding reference signal according to the configuration information sent by the first device, thereby sending the uplink sounding reference signal. The first device may receive the uplink sounding reference signal and perform subsequent processing.

[0098] S305: Measure the uplink sounding reference signal sent by the second device based on the configuration information.

[0099] The first device can measure the uplink measurement reference signal sent by the second device to obtain a measurement result, and determine the configuration information of the uplink data channel and the demodulation reference signal of the second device according to the measurement result.

[0100] Specifically, in an embodiment of the present disclosure, the first device receives an uplink measurement reference signal sent by the second device, and calculates channel information of the uplink measurement reference signal as a measurement result. The channel information can characterize the quality of the uplink measurement reference signal, including but not limited to at least one of signal to interference plus noise ratio (SINR), reference signal received power (RSRP), reference signal received quality (RSRQ), and received signal strength indication (RSSI), or any other parameter that can measure signal quality, which is not limited in the present disclosure.

[0101] S306: Determine configuration information of the uplink data channel and its demodulation reference signal of the second device according to the measurement result.

[0102] In an embodiment of the present disclosure, the first device may determine the configuration information of the uplink data channel and the demodulation reference signal of the second device according to a measurement result obtained by measuring the uplink sounding reference signal.

[0103] In a specific implementation, the first device may use the configuration information corresponding to the uplink sounding reference signal whose measurement result meets the communication condition as the configuration information of the uplink data channel and its demodulation reference signal of the second device.

[0104] For example, the first device may perform screening based on the principle of maximizing channel capacity, or select the antenna port and / or OAM mode corresponding to the uplink measurement reference signal with a better measurement result as the configuration information of the uplink data channel and its demodulation reference signal of the second device. The specific manner in which the first device determines the configuration information of the uplink data channel and its demodulation reference signal of the second device based on the measurement result is not limited in this disclosure.

[0105] S307: Send the configuration information of the uplink data channel and the demodulation reference signal of the second device to the second device.

[0106] In the present disclosure, the first device sends the determined configuration information of the uplink data channel and demodulation reference signal of the second device to the second device, so that the second device can perform uplink transmission of signals or data according to the configuration information, thereby completing the uplink transmission configuration in the OAM communication system.

[0107] In summary, according to the uplink transmission configuration method based on orbital angular momentum disclosed in the present invention, the first device can receive the capability information of the second device, determine the configuration information of the uplink measurement reference signal of the second device based on the capability information, and send the configuration information to the second device, wherein the configuration information includes at least one of the following: the OAM mode value of the uplink measurement reference signal; the antenna port corresponding to the OAM mode value, and send the configuration information to the second device, thereby completing the uplink transmission configuration suitable for the OAM communication scenario, effectively solving the resource configuration and mapping problems of the uplink transmission, and providing optional solutions to enhance applicability.

[0109] As shown in FIG4 , the method may include the following steps.

[0110] S401: Send an uplink sounding reference signal according to configuration information of the uplink sounding reference signal.

[0111] The configuration information of the uplink measurement reference signal includes at least one of the following: an OAM modal value of the uplink measurement reference signal; and an antenna port corresponding to the OAM modal value.

[0112] As described in the embodiments shown in Figures 1 to 3, when there is an association or binding relationship between the OAM modal value and the antenna port, the second device can determine the corresponding antenna port by receiving the OAM modal value from the first device, or can determine the corresponding OAM modal value by receiving the antenna port from the first device. When there is no association or binding relationship between the OAM modal value and the antenna port, the second device receives both the OAM modal value and the antenna port from the first device. For this, please refer to the embodiments shown in Figures 1 to 3 and will not be described in detail here.

[0113] The second device may generate a transmission beam of the uplink sounding reference signal according to the received configuration information of the uplink sounding reference signal, so as to send the uplink sounding reference signal to the first device.

The second device of the present disclosure can send an uplink signal according to the configuration of the first device, providing an uplink transmission configuration scheme suitable for OAM communication scenarios, effectively solving the resource configuration and mapping problems of uplink transmission.

[0115] It should be understood that this embodiment can be implemented alone or in combination with the aforementioned embodiment. For example, the second device can obtain the configuration information of the uplink measurement reference signal according to the method described in the aforementioned embodiment, such as first sending its own capability information to the first device, and then receiving the configuration information sent by the first device, and sending the uplink measurement reference signal according to the configuration information, etc. The present disclosure does not limit this.

[0116] In a possible implementation, the method may further include: receiving configuration information of an uplink data channel and a demodulation reference signal thereof.

[0117] The configuration information of the uplink data channel and its demodulation reference signal is determined by the first device based on a measurement result of the uplink sounding reference signal.

[0118] Figure 5 is a flow chart of a method for configuring uplink transmission based on orbital angular momentum according to an embodiment of the present disclosure.

[0121] It is understood that the maximum number of transmit OAM modes supported by the second device is related to the hardware configuration of the second device, specifically, the number of antenna elements of the second device. For example, assuming that the second device is configured with 8 antenna elements, the maximum number of transmit OAM modes supported by the second device is 8.

[0122] In addition, the capability information of the second device may also include identifiers of each modality supported by the second device, for example, each modality may be numbered with an integer. In the above example, the eight OAM modalities may be numbered with integers from 1 to 8. The identifier uniquely identifies the OAM mode, and the size or order of the identifier does not impose any restrictions on the modalities themselves.

[0123] S502: Receive configuration information of an uplink sounding reference signal sent by a first device.

[0124] It can be understood that the configuration information of the uplink measurement reference signal includes at least one of the following: the OAM modal value of the uplink measurement reference signal; and the antenna port corresponding to the OAM modal value.

[0125] S503: Determine time-frequency resource information and a sending method of an uplink sounding reference signal according to a communication protocol between the first device and the second device.

[0126] In an optional embodiment, the configuration information of the uplink sounding reference signal may further include time-frequency resource information and a transmission mode of the uplink sounding reference signal. In this case, the first device may configure the time-frequency resource information and the transmission mode of the uplink sounding reference signal and send it to the second device. The second device may receive the information from the first device in step S502.

[0127] In another optional embodiment, the second device may determine the time-frequency resource information and the sending mode of the uplink sounding reference signal according to the communication protocol between the first device and the second device. In this case, the second device may autonomously determine the information according to the protocol.

[0128] In other words, step S503 is an optional step. When the configuration information received in step S502 includes the time-frequency resource information and the sending method of the uplink measurement reference signal, that is, the information is configured by the first device, step S503 does not need to be executed. When the configuration information received in step S502 does not include the time-frequency resource information and the sending method of the uplink measurement reference signal, that is, the information is agreed upon through a protocol between the first device and the second device, step S503 is executed.

[0129] In the present disclosure, the configuration information of the uplink sounding reference signal received by the second device may refer to the embodiments shown in FIG. 1 and FIG. 2 , and will not be described in detail here.

The second device receives the configuration information of the uplink data channel and its demodulation reference signal sent by the first device, thereby completing the uplink transmission configuration in the OAM communication system, that is, the second device can generate a transmission beam of the data channel and its demodulation reference signal according to the configuration information to perform subsequent uplink transmission of signals or data.

[0135] In the present disclosure, the base station has configuration and decision-making capabilities, and the relay and / or terminal can transmit and receive beams according to the configuration of the base station without making any selection or judgment, but the present disclosure does not restrict the relay and / or terminal to have certain decision-making capabilities.
