Thus, the network device can learn the working mode supported by the smart metasurface, and then can control the smart metasurface accordingly according to application requirements.

[0007] Optionally, the reporting of the working mode includes: reporting the working mode during a random access process.

[0008] By reporting the working mode during the random access process, the network equipment can promptly learn the working mode supported by the smart metasurface without affecting the subsequent data transmission process.

Thus, the network device is implicitly informed of the working mode supported by the smart metasurface, saving uplink overhead.

After receiving the indication message, the intelligent reflective surface control device adjusts the working mode of the intelligent reflective surface to the target working mode, so as to better provide services for the terminal device and the network device.

[0026] Optionally, obtaining the working mode supported by the smart reflecting surface includes: obtaining a frequency domain position corresponding to a received physical random access sequence; and determining the working mode supported by the smart reflecting surface based on the frequency domain position corresponding to the physical random access sequence.

[0027] The intelligent reflective surface control device obtains the frequency domain position corresponding to the working mode from the physical random access channel configuration information, and sends the physical random access sequence at the frequency domain position corresponding to the working mode supported by the intelligent metasurface. The network device determines the working mode supported by the intelligent metasurface based on the frequency domain position corresponding to the received physical random access sequence. As a result, the intelligent reflective surface control device implicitly informs the network device of the working mode supported by the intelligent metasurface, saving overhead.

[0028] Optionally, the network device may send configuration information of a physical random access channel to the intelligent reflector control device; the configuration information of the physical random access channel is used to indicate a mapping relationship between a frequency domain position and a working mode.

[0043] In the prior art, with the continuous development of technology, the intelligent reflective surface can support different working modes, such as supporting only the reflection working mode, supporting only the transmission working mode, supporting both the reflection working mode and the transmission working mode, etc. However, the network device may not be able to know the working mode supported by the intelligent reflective surface, and thus cannot intelligently adjust the parameters of the intelligent reflective surface.

[0044] In the embodiment of the present invention, after obtaining the working mode supported by the intelligent metasurface, the intelligent reflective surface control device reports the working mode supported by the intelligent metasurface. Thus, the network device can learn the working mode supported by the intelligent metasurface, and then can control the intelligent metasurface accordingly according to application requirements.

In some embodiments, the network device may also be a device having a wireless communication function for a terminal device, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

[0048] In some embodiments, the network device may also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0049] The embodiment of the present invention provides a working mode reporting method, referring to Figure 1 , the following is a detailed description through specific steps.

[0050] In a specific implementation, the working mode reporting method described below can be executed by a chip with data processing function in the RIS control device, or by a chip module with data processing function in the RIS control device, or by the RIS control device.

[0051] The following description will be made by taking the RIS control device executing the working mode reporting method described in the following steps 101 to 102 as an example.

[0052] It should be noted that the RIS control device can also be called a RIS controller, a RIS control device, etc. The RIS control device can receive a wireless signal transmitted by a transmitter (hereinafter referred to as an incident signal), process the incident signal, and control the RIS according to relevant parameters of the incident signal (such as amplitude, frequency, phase), thereby making corresponding adjustments to relevant parameters of the outgoing signal (such as amplitude, frequency, phase, etc.).

[0053] In a specific application, the RIS control device may be integrated with the RIS, or the two may be independently separated.

[0054] Step 101, obtaining the working mode supported by the smart metasurface.

[0055] In an embodiment of the present invention, the RIS control device can obtain the working mode supported by the intelligent metasurface.

[0056] In specific applications, it can be known that the working modes supported by the smart metasurface may be one or more. Different types of smart metasurfaces may support different working modes.

[0057] In some embodiments, the smart metasurface supports only the reflection working mode. For a smart metasurface that supports only the reflection working mode, the received signal can be reflected. For example, a network device transmits a signal, and the smart metasurface receives the signal and reflects the signal so that the terminal device can receive the signal.

[0058] In other embodiments, the smart metasurface only supports the transmission working mode. For the smart metasurface that only supports the transmission working mode, the received signal can be transparently transmitted.

[0059] In some other embodiments, the smart metasurface may also support a transmission mode and a reflection mode, that is, the smart metasurface may integrate the reflection function and the transmission function. The smart metasurface (Simultaneously Transmitting and Reflecting, Surface, STARS) that integrates the reflection function and the transmission function can achieve 360° coverage and has more degrees of freedom compared to the smart metasurface that only supports a single function.

[0060] STARS can support the working mode of reflection-transmission energy splitting, the working mode of reflection-transmission mode switching, the working mode of reflection-transmission time-sharing switching, etc.

[0061] Specifically, in the reflection-transmission energy splitting (ES) working mode, each electromagnetic unit of STARS is in a superposition state of reflection and transmission, and each electromagnetic unit has adjustable amplitude and phase control, which can obtain the optimal beamforming gain, but the adjustment complexity is relatively high.

[0062] In the reflection-transmission mode switching (MS) working mode, the electromagnetic units of STARS are divided into two groups, one group of electromagnetic units works in the reflection working mode only, and the other group of electromagnetic units works in the transmission working mode only. In this scenario, STARS can be regarded as a combination of a RIS that only supports the reflection working mode and a RIS that only supports the transmission working mode. However, since the electromagnetic units do not participate in both reflection and transmission, the maximum beamforming gain cannot be obtained.

[0063] In the reflection-transmission time-switching (TS) working mode, the working mode of STARS periodically alternates between the reflection-only working mode and the transmission-only working mode. In this working mode, the communication design optimization of the reflection process and the transmission process are independent of each other, but the working mode of the electromagnetic unit in STARS needs to be switched frequently, which has high requirements for clock synchronization.

[0064] Step 102: Report the working mode.

[0065] In the embodiment of the present invention, after the RIS control device obtains the working mode supported by the intelligent metasurface, it can report the working mode supported by the intelligent metasurface.

[0066] In some embodiments, the RIS control device may send the operating modes supported by the smart metasurface to the network device, so that the network device can learn which operating modes the smart metasurface supports.

[0067] In the embodiment of the present invention, the RIS control device may report the working mode during the random access process.

[0068] In a specific implementation, during random access, the network device may send physical random access channel (PRACH) configuration information to the RIS control device. In the PRACH configuration information, multiple frequency domain positions for reporting PRACH sequences are configured. One working mode of the smart metasurface may correspond to one or more frequency domain positions.

[0069] In some embodiments, each frequency domain position for reporting the PRACH sequence may correspond to one or more operating modes supported by the smart metasurface. In other words, the frequency domain position and the operating mode supported by the smart metasurface may correspond one to one. Alternatively, one operating mode supported by the smart metasurface may correspond to two or more frequency domain positions.

[0070] In a specific implementation, the mapping relationship between the working mode of the smart metasurface and the frequency domain position can be known in advance by the network equipment and the RIS control device.

[0071] Specifically, the mapping relationship between the working mode of the smart metasurface and the frequency domain position can be pre-defined in the communication protocol. Alternatively, the network device can pre-send configuration information to the RIS control device, and the configuration information carries the mapping relationship between the working mode of the smart metasurface and the frequency domain position.

[0072] The RIS control device receives the PRACH configuration information and sends the PRACH sequence at the frequency domain position corresponding to the working mode supported by the smart metasurface. When the network device receives the PRACH sequence, it can determine the frequency domain position corresponding to the PRACH, and then determine the working mode supported by the smart metasurface.

[0073] For example, the working mode corresponding to frequency domain position 1 is set to support only the reflection working mode, the working mode corresponding to frequency domain position 2 is set to support only the transmission working mode, the working mode corresponding to frequency domain position 3 is set to the reflection-transmission energy splitting (ES) working mode, the working mode corresponding to frequency domain position 4 is set to the reflection-transmission mode switching (MS) working mode, and the working mode corresponding to frequency domain position 5 is set to the transmission-transmission time-sharing switching (TS) working mode. The RIS control device learns that the working mode currently supported by the smart metasurface is only the reflection working mode. The RIS control device sends the PRACH sequence at frequency domain position 1. The network device detects the PRACH sequence at frequency domain position 1, so it can determine that the working mode supported by the smart metasurface is only the reflection working mode.

[0074] It is understandable that if the smart metasurface has other supported working modes, or the smart metasurface can simultaneously support a combination of two or more of the above five working modes, more frequency domain positions can be used to characterize other working modes or combined working modes.

[0075] For example, the working mode supported by the intelligent metasurface includes the TS+MS multi-selection mode. Then the frequency domain position 6 is set to correspond to the TS+MS multi-selection mode. The RIS control device sends the PRACH sequence at the frequency domain position 6, and the network device can determine that the working mode supported by the intelligent metasurface is the TS+MS multi-selection mode.

[0076] In a specific implementation, the working mode supported by the smart metasurface can be carried in the random access message content. Specifically, the RIS control device can report the working mode supported by the smart metasurface through the msg3 message.

[0077] In some embodiments, the working modes that may be supported by the smart metasurface are set to include: only supporting reflection working mode, only supporting transmission working mode, reflection-transmission energy splitting (ES) working mode, reflection-transmission mode switching (MS) working mode, reflection-transmission time-sharing switching (TS) working mode, and TS+MS multiple selection mode.

[0078] In this scenario, 4-bit information can be defined to characterize the working modes supported by the smart metasurface. The 4-bit information is carried in the msg3 message. Specifically, when the bit value of the 4-bit information is 0001, it indicates that the smart metasurface only supports the reflection working mode; when the bit value of the 4-bit information is 0010, it indicates that the smart metasurface only supports the transmission working mode; when the bit value of the 4-bit information is 0100, it indicates that the smart metasurface supports the reflection-transmission energy splitting (ES) working mode; when the bit value of the 4-bit information is 1000, it indicates that the smart metasurface supports the reflection-transmission mode switching (MS) working mode; when the bit value of the 4-bit information is 0011, it indicates that the smart metasurface supports the reflection-transmission time-sharing switching (TS) working mode; when the bit value of the 4-bit information is 0111, it indicates that the smart metasurface supports the TS+MS multi-selection mode.

[0079] In other embodiments, the working modes that may be supported by the smart metasurface are set to include the following: only supporting reflection working mode, only supporting transmission working mode, reflection-transmission energy splitting (ES) working mode, reflection-transmission mode switching (MS) working mode, and reflection-transmission time-sharing switching (TS) working mode.

[0080] In this scenario, 3-bit information can be defined to characterize the working modes supported by the smart metasurface. The 3-bit information is carried in the msg3 message. Specifically, when the bit value of the 3-bit information is 001, it indicates that the smart metasurface only supports the reflection working mode; when the bit value of the 3-bit information is 010, it indicates that the smart metasurface only supports the transmission working mode; when the bit value of the 3-bit information is 100, it indicates that the smart metasurface supports the reflection-transmission energy splitting (ES) working mode; when the bit value of the 3-bit information is 110, it indicates that the smart metasurface supports the reflection-transmission mode switching (MS) working mode; when the bit value of the 3-bit information is 111, it indicates that the smart metasurface supports the reflection-transmission time-sharing switching (TS) working mode.

[0081] It is understandable that the number of bits representing the working modes supported by the smart metasurface can be set according to the actual scenario, and is not limited to the above 3 bits and 4 bits. The mapping relationship between different bit values ​​and working modes can also be set according to specific scenarios, and is not limited to the above examples.

[0082] In an embodiment of the present invention, the RIS control device can report the working mode supported by the smart metasurface in a radio resource control (Radio Resource Control, RRC) connection state.

[0083] In a specific implementation, the RIS control device may report the working mode supported by the intelligent metasurface through a physical uplink control channel (PUCCH). In other words, the working mode supported by the intelligent metasurface may be carried in the PUCCH.

[0084] Alternatively, the RIS control device may report the working mode supported by the intelligent metasurface via a physical uplink shared channel (PUSCH). In other words, the working mode supported by the intelligent metasurface may be carried in the PUSCH.

[0085] In some embodiments, the working modes that may be supported by the smart metasurface are set to include: only supporting reflection working mode, only supporting transmission working mode, reflection-transmission energy splitting (ES) working mode, reflection-transmission mode switching (MS) working mode, reflection-transmission time-sharing switching (TS) working mode, and TS+MS multiple selection mode.

[0086] In this scenario, 4-bit information can be defined to characterize the working modes supported by the smart metasurface. The 4-bit information is carried in the msg3 message. Specifically, when the bit value of the 4-bit information is 0001, it indicates that the smart metasurface only supports the reflection working mode; when the bit value of the 4-bit information is 0010, it indicates that the smart metasurface only supports the transmission working mode; when the bit value of the 4-bit information is 0100, it indicates that the smart metasurface supports the reflection-transmission energy splitting (ES) working mode; when the bit value of the 4-bit information is 1000, it indicates that the smart metasurface supports the reflection-transmission mode switching (MS) working mode; when the bit value of the 4-bit information is 0011, it indicates that the smart metasurface supports the reflection-transmission time-sharing switching (TS) working mode; when the bit value of the 4-bit information is 0111, it indicates that the smart metasurface supports the TS+MS multi-selection mode.

[0087] In other embodiments, the working modes that may be supported by the smart metasurface are set to include the following: only supporting reflection working mode, only supporting transmission working mode, reflection-transmission energy splitting (ES) working mode, reflection-transmission mode switching (MS) working mode, and reflection-transmission time-sharing switching (TS) working mode.

[0088] In this scenario, 3-bit information can be defined to characterize the working modes supported by the smart metasurface. The 3-bit information is carried in the msg3 message. Specifically, when the bit value of the 3-bit information is 001, it indicates that the smart metasurface only supports the reflection working mode; when the bit value of the 3-bit information is 010, it indicates that the smart metasurface only supports the transmission working mode; when the bit value of the 3-bit information is 100, it indicates that the smart metasurface supports the reflection-transmission energy splitting (ES) working mode; when the bit value of the 3-bit information is 110, it indicates that the smart metasurface supports the reflection-transmission mode switching (MS) working mode; when the bit value of the 3-bit information is 111, it indicates that the smart metasurface supports the reflection-transmission time-sharing switching (TS) working mode.

[0089] It is understandable that the number of bits representing the working modes supported by the smart metasurface can be set according to the actual scenario, and is not limited to the above 3 bits and 4 bits. The mapping relationship between different bit values ​​and working modes can also be set according to specific scenarios, and is not limited to the above examples.

[0090] It can be seen that, by adopting the technical solution provided in the above embodiment, after obtaining the working mode supported by the intelligent metasurface, the intelligent reflective surface control device reports the working mode supported by the intelligent metasurface. As a result, the network device can learn the working mode supported by the intelligent metasurface, and then can control the intelligent metasurface accordingly according to application requirements.

[0091] In an embodiment of the present invention, after learning the working modes supported by the smart metasurface, the network device can determine the target working mode of the smart metasurface according to the current network status, the needs of the terminal device, etc. The network device can send indication information to the RIS control device, and the indication information can be used to indicate the target working mode of the smart reflective surface. The RIS control device receives the indication information and can adjust the working mode of the smart reflective surface according to the indication information. Specifically, the RIS control device can adjust the working mode of the smart reflective surface to the target working mode indicated by the indication information.

[0092] In a specific implementation, the network device can obtain the working mode supported by the smart metasurface through the solutions provided in the above steps 101 to 102.

[0093] In some embodiments, the network device may also be informed in advance of the operating modes supported by the smart metasurface. For example, when setting up the smart metasurface, the network device is notified in advance of the operating modes supported by the smart metasurface.

[0094] In a specific implementation, the network device may send RRC configuration information to the RIS control device, and the RRC configuration information may be used to indicate the candidate working modes of the smart reflective surface. The RIS control device receives the indication information and determines the target working mode from the candidate working modes.

[0095] In some embodiments, in the RRC configuration information, 3-bit information can be defined to characterize the candidate working modes of the smart metasurface. Specifically, when the bit value of the 3-bit information is 001, the candidate working mode characterizing the smart metasurface is a working mode that only supports reflection; when the bit value of the 3-bit information is 010, the candidate working mode characterizing the smart metasurface is a working mode that only supports transmission; when the bit value of the 3-bit information is 100, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission energy splitting (ES); when the bit value of the 3-bit information is 110, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission mode switching (MS); when the bit value of the 3-bit information is 111, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission time-sharing switching (TS).

[0096] The network device sends an indication message to the RIS control device, and the 3 bits carried by the indication message have a value of 111. Thus, the RIS control device determines that the target working mode of the smart metasurface is a working mode that supports reflection-transmission time-sharing switching (TS). In a specific implementation, the network device may also send the indication message via downlink control information (DCI).

[0097] In a specific implementation, the network device may also directly send the indication information through a physical downlink control channel (Physical Downlink Control Channel, PDCCH), or the network device may send the indication information through a physical downlink control channel (Physical Downlink Shared Channel, PDSCH).

[0098] In some embodiments, in PDCCH or PDSCH, 3-bit information can be defined to characterize the candidate working modes of the smart metasurface. Specifically, when the bit value of the 3-bit information is 001, the candidate working mode characterizing the smart metasurface is a working mode that only supports reflection; when the bit value of the 3-bit information is 010, the candidate working mode characterizing the smart metasurface is a working mode that only supports transmission; when the bit value of the 3-bit information is 100, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission energy splitting (ES); when the bit value of the 3-bit information is 110, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission mode switching (MS); when the bit value of the 3-bit information is 111, the candidate working mode characterizing the smart metasurface is a working mode that supports reflection-transmission time-sharing switching (TS).

[0099] The network device sends an indication message to the RIS control device, and the 3 bits carried by the indication message have a value of 110. Therefore, the RIS control device determines that the target working mode of the smart metasurface is a working mode supporting reflection-transmission mode switching (MS).

[0100] Reference Figure 2 , a working mode indication method in the present invention is given, and is described in detail through specific steps below.

[0101] The working mode indication method described below may be executed by a chip having a data processing function in a network device, or may be executed by a chip module having a data processing function in the network device, or may be executed by the network device.

[0102] Step 201: Obtain the working modes supported by the smart reflective surface.

[0103] In a specific implementation, the network device may first send configuration information of a physical random access channel to the RIS control device, and configure multiple frequency domain positions for reporting PRACH sequences in the PRACH configuration information. A working mode of the smart metasurface may correspond to one or more frequency domain positions.

[0104] In some embodiments, each frequency domain position for reporting the PRACH sequence may correspond to an operating mode of the smart metasurface. In other words, the frequency domain position and the operating mode of the smart metasurface may correspond one to one.

[0105] In a specific implementation, the mapping relationship between the working mode of the smart metasurface and the frequency domain position can be known in advance by the network equipment and the RIS control device.

[0106] Specifically, the mapping relationship between the working mode of the smart metasurface and the frequency domain position can be pre-defined in the communication protocol. Alternatively, the network device can pre-send configuration information to the RIS control device, and the configuration information carries the mapping relationship between the working mode of the smart metasurface and the frequency domain position.

[0107] In a specific implementation, the network device can obtain the working mode supported by the intelligent reflective surface from the msg3 message.

[0109] Specifically, the specific process of the network device obtaining the working mode supported by the intelligent reflective surface can refer to the solutions provided in the above steps 101 to 102 to obtain the working mode supported by the intelligent metasurface.

[0110] In some embodiments, the network device may also be informed in advance of the operating modes supported by the smart metasurface. For example, when setting up the smart metasurface, the network device is notified in advance of the operating modes supported by the smart metasurface.

[0111] Step 202: Send instruction information.

[0112] In a specific implementation, the network device may send the indication information via the PDSCH, or the network device may send the indication information via the PDCCH.

[0113] In a specific implementation, the network device may send RRC configuration information to the RIS control device, and the RRC configuration information may be used to indicate the candidate working modes of the smart reflective surface. The RIS control device receives the indication information and determines the target working mode from the candidate working modes.

[0114] In a specific implementation, the specific execution process of the above steps 201 to 202 may correspond to the above steps 101 to 102, which will not be described in detail here.

[0115] In the embodiment of the present invention, after obtaining the working mode supported by the intelligent reflective surface, the network device sends indication information to the intelligent reflective surface control device to indicate the target working mode of the intelligent reflective surface. The intelligent reflective surface control device receives the indication information and adjusts the working mode of the intelligent reflective surface to the target working mode, so as to better provide services for the terminal device and the network device.

[0119] In a specific implementation, the specific execution process of the working mode reporting device 30 may correspond to step 101 to step 102, which will not be described in detail here.

[0120] In a specific implementation, the working mode reporting device 30 may correspond to a chip with a data processing function in a RIS control device, or to a chip module including a chip with a data processing function in a RIS control device, or to a RIS control device.
