[0066] The continuous emergence of new internet applications such as augmented reality (AR) / virtual reality (VR) and vehicle-to-vehicle communications has placed higher demands on wireless communication technology, driving its continuous evolution to meet these demands. Currently, cellular mobile communication technology is in the process of evolving into a new generation of technology. A key feature of this new generation of technology is its flexible configuration support for multiple service types. Different service types have different requirements for wireless communication technology. For example, enhanced mobile broadband (eMBB) services focus on large bandwidth and high speeds; ultra-reliable low latency (uRLLC) services require high reliability and low latency; and massive machine-type communications (mMTC) services require a large number of connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission needs of various service types.

[0067] In traditional communications, the wireless environment is an uncontrollable factor. This uncontrollability often negatively impacts communication efficiency and reduces service quality. Signal attenuation limits the propagation distance of wireless signals, multipath effects cause fading, and reflection and refraction from large objects are major uncontrollable factors.

[0068] To this end, this embodiment proposes a communication processing method and apparatus, which can reflect the first network device signal incident on its surface in a specific direction by deploying a second network device in a wireless transmission environment, such as a RIS-type device, to enhance the signal strength of the receiving terminal device, thereby providing an effective related configuration and control solution.

[0069] The communication processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0070] FIG1 shows a structural diagram of a communication processing system according to an embodiment of the present disclosure. As shown in FIG1 , the system architecture may include a first network device 11 , a second network device 12 , and a terminal device 13 .

[0071] In some examples, the first network device 11 may be an entity on the network side for transmitting or receiving signals. For example, the first network device 11 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the first network device 11. The first network device 11 provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are centrally controlled by the CU, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0072] In some examples, the second network device 12 may be a reconfigurable intelligent surface (RIS) type network device, equipped with a RIS array. For example, deploying RIS on various surfaces within a wireless transmission environment can overcome the uncontrollability of traditional wireless channels and build intelligent, programmable wireless networks. RIS can utilize precoding technology to reflect incident signals in a specific direction, thereby enhancing signal strength at the receiving end and achieving channel control.

[0073] In some examples, the terminal device 13 can be called a terminal, user equipment, mobile station (MS), mobile terminal (MT), etc. The terminal device 13 can also be a car with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality device, an augmented reality device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal device 13.

[0074] In some examples, the first network device 11 can obtain capability information of the second network device 12; the first network device 11 sends first configuration information of a reference signal to the second network device 12 based on the capability information of the second network device 12, and sends second configuration information of the reference signal to the terminal device 13; the second network device 12 sends the reference signal to the terminal device 13 based on the first configuration information; and the terminal device 13 performs measurement and evaluation based on the received reference signal and the second configuration information to obtain a measurement result, and the terminal device 13 sends CSI to the first network device 11, and the CSI includes the measurement result; the second network device 12 sends indication information to the second network device 12 based on the CSI and the capability information of the second network device, and the second network device 12 determines a precoding matrix based on the indication information, and the precoding matrix includes a phase shift matrix; the second network device 12 uses the precoding matrix to reflect or transmit the signal.

[0075] Through the above-mentioned communication processing scheme, the second network device deployed in the wireless transmission environment can reflect the first network device signal incident on its surface to a specific direction to enhance the signal strength of the receiving terminal device, and provide effective related configuration and control solutions.

[0076] Furthermore, to illustrate the specific execution process of the first network device, Figure 2 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to the first network device and may include the following steps.

[0077] Step 201: A first network device obtains capability information of a second network device.

[0078] The capability information of the second network device may include relevant capability information of the second network device, so as to determine a transmission scheme based on the second network device and configure and regulate the second network device based on the capability information of the second network device.

[0079] In some examples, the first network device may first determine the type information of the second network device. If it is determined that the type of the second network device is a specific type, such as a RIS-type network device, the first network device may further obtain capability information of the second network device of the RIS type and continue to execute the processes shown in the following steps 202 to 204 to configure and regulate the second network device of the RIS type.

[0080] Step 202: The first network device sends first configuration information of a reference signal to the second network device according to the received capability information of the second network device, and sends second configuration information of a reference signal to the terminal device.

[0081] A reference signal (RS) is a "pilot" signal that can be used for channel estimation or channel sounding, etc. The first configuration information of the reference signal can be used to instruct the second network device on how to send the reference signal to the terminal device. That is, the first network device can send the first configuration information to the second network device so that the second network device sends the reference signal to the terminal device according to the configuration information. For the terminal device, the terminal device can receive the second configuration information sent by the first network device to measure and evaluate the reference signal according to the second configuration information to obtain a measurement result. That is, the second configuration information of the reference signal can be used for the measurement result obtained by the terminal device based on the measurement and evaluation of the reference signal sent by the second network device.

[0082] Step 203: The first network device receives channel state information (CSI) sent by the terminal device.

[0083] The CSI indicates the channel state of the reference signal and reflects the channel condition of the reference signal. In some embodiments, the CSI may include a measurement result obtained by the terminal device based on the second configuration information and the reference signal through measurement and evaluation.

[0084] Step 204: The first network device sends indication information to the second network device based on the CSI and the capability information of the second network device.

[0085] The indication information is used by the second network device to determine a precoding matrix, wherein the precoding matrix may include a phase shift matrix, so that the second network device can use the precoding matrix to reflect or transmit signals.

[0086] For example, the second network device is a RIS-type network device. The first network device can analyze the incident condition of the signal beam based on the capability information of the RIS-type network device, and analyze the reflection condition of the signal beam based on the CSI containing the measurement results. Then, based on the incident condition and reflection condition of the signal beam, the first network device can further determine the indication information. The indication information can be used by the RIS-type network device to determine the precoding matrix used by the RIS units therein, so that these RIS units can use the values ​​at their respective corresponding positions in the precoding matrix to reflect or transmit the signal in the specified direction to enhance the signal strength at the receiving end.

[0087] In some embodiments according to the present disclosure, the first network device, the second network device, and the terminal device described may be the first network device 11, the second network device 12, and the terminal device 13 in the aforementioned embodiments.

[0088] The communication processing method provided in this embodiment can enhance the signal strength of the receiving terminal device by reflecting the first network device signal incident on its surface in a specific direction through a second network device deployed in a wireless transmission environment, such as a RIS-type network device, and provides effective related configuration and control solutions.

[0089] Figure 3 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. Based on the embodiment shown in Figure 2, as shown in Figure 3, the method is applied to the first network device and may include the following steps.

[0090] Step 301: A first network device obtains type information of a second network device.

[0091] The type information of the second network device may include a RIS type. For example, if the second network device establishes a network connection with the first network device, the second network device may provide the RIS type information of the second network device to the first network device through the network connection.

[0092] For another example, relevant data of the second network device may be pre-configured in the core network, and the first network device may obtain type information of the second network device through an operation administration and maintenance (OAM) system associated with the core network.

[0093] Step 302: The first network device obtains capability information of the second network device.

[0094] For example, if the second network device establishes a network connection with the first network device, the second network device may provide the capability information of the second network device to the first network device through the network connection.

[0095] For another example, relevant data of the second network device may be pre-configured in the core network, and the first network device may obtain capability information of the second network device through an OAM system associated with the core network.

[0096] In some examples, if the type information of the second network device includes a RIS type, the capability information of the second network device may include at least one of the following:

[0097] The operating frequency bands supported by the RIS array; the operating modes of the RIS array, such as reflection and transmission; the scale information of the RIS array, such as the number of RIS units, the number of rows and columns of RIS units, etc.; the control capability information of the RIS array; the active RIS unit information of the RIS array; the deployment information of the RIS array, etc.

[0098] For example, if the second network device is a RIS device, the first network device obtains capability information from the RIS device and, based on this information, determines a transmission scheme for the RIS device and configures and controls the RIS device. Compared to configuring and controlling the RIS using alternating optimization techniques (which involve optimizing multiple algorithms and are highly complex), this embodiment provides an effective configuration and control scheme for the RIS device. Through collaboration between the first network device (such as a base station) and the RIS device, configuration and control of RIS channel estimation, precoding, and other features are implemented, reducing the complexity of configuring and controlling the RIS device.

[0099] In some examples, the control capability information of the RIS array includes at least one of the following:

[0100] The control accuracy of the RIS unit, such as the number of bits that the RIS unit can control; beam width; beam coverage angle range; beam adjustment response time, such as the time it takes to complete the shaping from beam A to beam B; the adjustment range of the RIS unit reflection coefficient, such as used to control the reflection / transmission power, etc.

[0101] In some examples, the active RIS cell information of the RIS array includes at least one of the following:

[0102] The operating frequency band of the active RIS unit; the number of active RIS units; the location information of the active RIS unit, such as the row number and column number of the active RIS unit; the transmission bandwidth of the active RIS unit; the transmission power information of the active RIS unit, such as the maximum transmission power of the active RIS unit.

[0103] In some examples, the deployment information of the RIS array may include position information of the RIS array and direction information of the RIS array. For example, the position information of the RIS array may include the normal direction of the RIS array; the direction information of the RIS array may include coordinate information, etc.

[0104] Step 303: The first network device sends first configuration information of a reference signal to the second network device according to the capability information of the second network device, and sends second configuration information of a reference signal to the terminal device.

[0105] In some examples, step 303 may specifically include: the first network device determines first configuration information and second configuration information of the reference signal based on the active RIS unit information, wherein the first configuration information may include the first active RIS unit used to send the reference signal, the time-frequency domain position of the reference signal, and the sequence information of the reference signal; the second configuration information may include the time-frequency domain resources used by the reference signal; the first network device sends the first configuration information to the second network device, and sends the second configuration information to the terminal device.

[0106] For example, the second network device may send a reference signal to the terminal device based on the first active RIS unit used to send the reference signal, the time-frequency domain position of the reference signal, and the sequence information of the reference signal. The terminal device may perform measurement and evaluation based on the time-frequency domain resources used by the reference signal and the reference signal to obtain a measurement result.

[0107] In some examples, if the second network device does not have an active RIS unit, the first network device may not need to send the first configuration information to the second network device. Instead, the first network device may send a reference signal to the RIS-type second network device, which may then reflect or transmit the reference signal to the terminal device. Specifically, the method may further include the first network device sending the reference signal to the second network device, and upon receiving the reference signal, the second network device may forward the reference signal to the terminal device.

[0108] In some examples, the method of this embodiment may further include: transmitting to the second network device a RIS operating frequency band selected from the operating frequency bands supported by the RIS array. For example, based on the frequency bands supported by the RIS, a RIS-based operating frequency band is selected so that the second network device can operate using the RIS operating frequency band.

[0109] Step 304: The first network device receives the CSI sent by the terminal device.

[0110] The CSI may include a measurement result obtained by the terminal device through measurement and evaluation based on the second configuration information and the reference signal. In some examples, the measurement result may include a PMI and / or a beam measurement result.

[0111] In some examples, the beam measurement results include at least one of the following:

[0112] Measurement reference signal identification; RSRP; RSRQ; SINR, etc.

[0113] Step 305: The first network device sends indication information to the second network device based on the CSI and the capability information of the second network device.

[0114] The indication information may be used by the second network device to determine a precoding matrix, where the precoding matrix may include a phase shift matrix.

[0115] In some examples, step 305 may specifically include: sending indication information of the precoding matrix to the second network device according to the PMI, scale information of the RIS array, control capability information of the RIS array, and deployment information of the RIS array.

[0116] For example, taking the first network device as a base station and the second network device as a RIS device, the base station can determine the incident angle information from the base station to the RIS device based on the deployment information of the RIS array; and determine the accuracy of the RIS device's precoding or beam indication information, as well as the reflection / transmission coefficient of the RIS device, based on the control capability of the RIS array. In this example, the precoding matrix indication information sent by the base station to the RIS device may include: assuming the RIS device has a continuous phase shift, determining the precoding matrix used by each RIS unit based on the PMI, incident angle information, and RIS array scale information. For example, beam matrix information related to the reflection angle can be analyzed from the PMI, and beam matrix information related to the incident angle can be analyzed from the incident angle information. Then, the beam matrix information related to the incident angle and the beam matrix information related to the reflection angle are processed to obtain the precoding matrix. Then, based on the control capability of the RIS array, such as the accuracy of the precoding or beam indication information of the RIS device and the reflection / transmission coefficient of the RIS device, the precoding matrix is ​​quantized to a phase shift supported by the RIS device according to a shortest distance criterion. Finally, the PMI and incident angle information are forwarded to the RIS device, and the precoding matrix determination and quantization processes are performed at the RIS device.

[0117] In some examples, step 305 may specifically include: sending beam indication information to the second network device based on the beam measurement result, scale information of the RIS array, control capability information of the RIS array, and deployment information of the RIS array. The beam indication information may include a Transmission Configuration Indicator (TCI) status identifier (ID).

[0118] A TCI state is associated with a specific reference signal (RS). The TCI state ID represents the beam of the associated RS. When a terminal device receives a TCI state indication, for downlink reception, during a specific time period, the terminal device assumes that the network is using the beam used for the RS associated with the TCI state. For uplink transmission, during a specific time period, the terminal device uses the receive spatial filter corresponding to the RS associated with the TCI state.

[0119] By applying the communication processing method provided in this embodiment, RIS devices deployed in a wireless transmission environment can reflect incident signals in a specific direction, thereby enhancing signal strength at the receiving end. This method also provides an effective solution for configuring and controlling related RIS devices. Through the collaboration between base stations and RIS devices, RIS channel estimation, precoding, and other configuration and control functions are implemented, reducing the complexity of RIS device configuration and control.

[0120] Figure 4 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to the second network device side (such as the second network device 12 in Figure 1) and may include the following steps.

[0121] Step 401: A second network device receives first configuration information of a reference signal sent by a first network device.

[0122] The first configuration information of the reference signal may be used to instruct the second network device how to send the reference signal to the terminal device.

[0123] Step 402: The second network device sends a reference signal to the terminal device based on the first configuration information.

[0124] The reference signal can be used for channel estimation or channel detection, etc.

[0125] Step 403: The second network device receives the instruction information sent by the first network device.

[0126] Step 404: The second network device determines a precoding matrix according to the indication information.

[0127] The precoding matrix may include a phase shift matrix.

[0128] Step 405: The second network device uses the precoding matrix to reflect or transmit the signal.

[0129] By applying the communication processing method provided in this embodiment, the signal of the first network device incident on its surface can be reflected in a specific direction by a second network device deployed in a wireless transmission environment to enhance the signal strength of the receiving terminal device, and an effective related configuration and control solution is provided.

[0130] Figure 5 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to the second network device and may include the following steps.

[0131] Step 501: The second network device sends type information of the second network device to the first network device.

[0132] The type information of the second network device may include a RIS type. For example, the second network device provides the RIS type information of the second network device to the first network device in an offline or online manner.

[0133] Step 502: The second network device sends capability information of the second network device to the first network device.

[0134] For example, the second network device provides the capability information of the second network device to the first network device in an offline or online manner. In some examples, if the type information of the second network device includes the RIS type, the capability information of the second network device may include at least one of the following:

[0135] The operating frequency bands supported by the RIS array; the operating mode of the RIS array; the scale information of the RIS array; the control capability information of the RIS array; the active RIS unit information of the RIS array; the deployment information of the RIS array, etc.

[0141] Step 503: The second network device receives first configuration information of the reference signal sent by the first network device.

In some examples, the first configuration information may include a first active RIS unit used to send the reference signal, the time-frequency domain location of the reference signal, and sequence information of the reference signal.

[0143] In some examples, the method of this embodiment may further include: the second network device receiving the RIS operating frequency band sent by the first network device; and operating using the RIS operating frequency band.

[0144] Step 504: The second network device sends a reference signal to the terminal device based on the first configuration information.

[0145] In some examples, if the second network device does not have an active RIS unit, the first network device may not need to send the first configuration information to the second network device. Instead, the first network device may send a reference signal to the RIS-type second network device, which may then reflect or transmit the reference signal to the terminal device. Specifically, the method may further include the first network device sending the reference signal to the second network device, and upon receiving the reference signal, the second network device may forward the reference signal to the terminal device.

[0146] Step 505: The second network device receives the instruction information sent by the first network device.

[0147] In some examples, the indication information may be indication information of a precoding matrix or beam indication information.

[0148] Step 506: The second network device determines a precoding matrix according to the indication information.

[0149] The precoding matrix may include a phase shift matrix.

[0150] Step 507: The second network device uses the precoding matrix to reflect or transmit the signal.
