Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 30, 2023, with application number 202310799507.7 and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0003] Smart metasurfaces, with their unique intelligent control of electromagnetic waves, provide unlimited possibilities for new wireless signal modulation hardware paradigms and intelligent wireless environments. Various new smart metasurface designs are constantly emerging with the following characteristics: 1. Currently, most smart metasurfaces only support one of the reflection-only or transmission-only modes; 2. A new type of simultaneously transmitting and reflecting surface (STARS) that integrates reflection and transmission functions. Compared with single-function reconfigurable intelligence surfaces (RIS), STARS can achieve 360° coverage and has more degrees of adjustment freedom.

[0004] In the prior art, STARS has the following control modes: 1. Reflection-Transmission Energy Splitting (ES): In this mode, all STARS electromagnetic units are in a superposition of reflection and transmission, with each unit having independently adjustable signal amplitude and phase control. 2. Reflection-Transmission Mode Switching (MS): In this mode, the STARS electromagnetic units are divided into two groups, each operating only in pure reflection or pure transmission. 3. Reflection-Transmission Time-Sharing Switching (TS): In this mode, the entire STARS system periodically alternates between pure reflection and pure transmission. While energy-splitting mode 1 has a higher control complexity, it can achieve optimal STARS beamforming gain. Compared to energy-splitting mode, mode 2 offers the advantage of greater practical implementation. Once all electromagnetic units are grouped, the mode-switched STARS can be considered a combination of a reflection-type RIS and a transmission-type RIS. However, since not all electromagnetic units participate in both reflection and transmission, this mode suffers from the disadvantage of not achieving maximum beamforming gain. Mode 3 allows for independent communication design optimization of the reflection and transmission signal processes. However, this mode requires frequent switching of the electromagnetic unit operating modes, placing high demands on clock synchronization.

[0005] However, existing smart surface controllers switch between different control modes, and how to configure the parameters of smart metasurfaces is a technical problem that needs to be solved urgently.

[0048] This application mainly relates to communication between terminal devices and network devices. The terminal device may be a reconfigurable intelligence surface (RIS), such as a smart surface controller.

[0049] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions.

The network device in the embodiment of the present application also includes a device that provides a base station function in a future new communication system, etc.

[0050] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0051] The intelligent surface controller in this embodiment can also be called RIS controller, reconfigurable intelligent surface controller, intelligent metasurface controller, controller, etc.

[0052] Specifically, the RIS consists of three sublayers and a smart surface controller. The outermost layer is composed of numerous reflective elements printed on a dielectric substrate, which directly interact with and reflect the incident signal. The second layer is typically a copper or other metal plate, whose primary function is to prevent the signal from penetrating the reflective surface and causing signal attenuation. The third layer is a control circuit board. Through the controller, the capacitance, resistance, and inductance values ​​of all reflective elements in the RIS can be independently adjusted to adjust the amplitude or phase of the reflected signal. The smart surface controller typically uses a field-programmable gate array (FPGA), which can control the reflection coefficient (including amplitude and phase) of each reflective element. PIN diodes are the most widely used in current smart surface structures. During processing, a PIN diode is connected to each reflective element. To switch the PIN diode between the "on" and "off" states in the equivalent circuit, the diode's bias voltage needs to be controlled via a DC feed circuit, thereby generating a phase shift difference. Therefore, by using FPGA to set the corresponding bias voltage on the smart surface, the phase shift of each reflective unit on the smart surface can be achieved. On this basis, the smart surface controller can be used to jointly adjust multiple (or even the entire smart surface) reflective units, thereby realizing the control of the reflected beamforming to meet the needs of different communication scenarios.

[0053] As described in the background technology, existing smart surface controllers switch between different control modes. How to configure the parameters of the smart metasurface is a technical problem that needs to be solved urgently.

[0054] In the technical solution of this application, first configuration information is used to configure the intelligent surface controller with parameters applicable to multiple control modes, allowing the intelligent surface controller to select a first parameter combination suitable for the current control mode, thereby achieving control of the reflection and / or transmission of electromagnetic waves. The technical solution of this application enables the intelligent surface controller to flexibly switch between different control modes, achieving flexible management of the intelligent surface controller. In addition, the above configuration also enables the intelligent surface controller to quickly and accurately adjust phase and beam in different control modes, serving the target terminal and improving the user communication experience.

[0055] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0056] Referring to FIG1 , the method provided in this application specifically includes the following steps:

[0057] Step 101: A network device sends first configuration information, where the first configuration information indicates multiple parameters applicable to multiple control modes, each parameter having at least one candidate value. Accordingly, the smart surface controller receives the first configuration information.

[0058] Step 102: The intelligent surface controller extracts a first parameter combination corresponding to the current control mode based on the first configuration information. Each first parameter combination includes multiple parameters and their target values. Specifically, the target value of a parameter is selected from candidate values ​​of the parameter, and the target value of the parameter is part or all of the candidate values ​​of the parameter.

[0059] Step 103: The smart surface controller controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode. Specifically, the smart surface controller can achieve reflection and / or transmission of electromagnetic waves by controlling the electromagnetic units of the smart surface.

[0060] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0061] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0062] In this embodiment, the first configuration information may be carried in a Radio Resource Control (RRC) signaling, that is, the RRC signaling sent by the network device to the smart surface controller includes the first configuration information.

[0063] In this embodiment, the control mode can be selected from a reflection-transmission energy split mode, a reflection-transmission mode switching mode, and a reflection-transmission time-sharing switching mode.

[0064] When configuring the parameters in the first configuration information, the network device may configure the first configuration information to include different contents, which will be described below in conjunction with specific embodiments.

[0065] Example 1: The first configuration information includes multiple parameter lists, each parameter list includes Z max Second parameter combinations, each of which includes multiple parameters of different working modes and their candidate values, where Z max Is a positive integer.

[0066] Referring to FIG. 2 , in step 201 , the network device sends the first configuration information to the smart surface controller.

[0067] In a specific embodiment, the multiple parameters may include one or more of time, first beam information and its operating mode, second beam information and its operating mode, and reflection-transmission power ratio. Specifically, the operating mode is selected from reflection and transmission.

[0068] For example, the specific form of the i-th parameter list Listi is as follows.

[0069] Among them, Time1 to TimeN represent various times, beamindex1 to beamindexN represent beams with indices 1-N respectively, R represents the working mode as reflection, T represents the working mode as transmission, and 1 / 2 to 3 / 4 represent the transmission-reflection power ratio. Specifically, N represents the number of times, and the value of N can be combined with the number of second parameter combinations Z max For example, when the second parameter combination corresponds to multiple times, the value of N is greater than Z. max .

[0070] In another specific embodiment, the multiple parameters include one or more of time, first beam information, second beam information, and a reflection-to-transmission power ratio. The first beam information and the second beam information each have a corresponding operating mode. For example, the default operating mode of beam information 1 is reflection, and the default operating mode of beam information 2 is transmission.

[0071] For example, the i-th parameter list List i The specific form is as follows.

[0072] Compared with the above-mentioned embodiment, the parameter list in this embodiment does not need to configure the working mode parameter, and the signaling overhead is smaller.

[0073] It should be noted that the working mode corresponding to the beam information may be specified by a communication standard protocol, or may be sent in advance by a network device to the smart surface controller.

[0074] In steps 202 and 203 , the smart surface controller extracts a first parameter combination corresponding to the current control mode according to the first configuration information, and controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode.

[0075] In a specific embodiment, the smart surface controller may periodically perform the above steps.

[0076] In another specific embodiment, the smart surface controller may receive second configuration information, the second configuration information including an identifier of an activated parameter list, and the first parameter combination is extracted from the activated parameter list.

[0077] Specifically, the network device may activate the parameter list by carrying the identifier of the parameter list in a Media Access Control (MAC) control element (CE), and the smart surface controller periodically executes the above steps according to the activated parameter list.

[0078] For example, the current control mode of the intelligent surface controller is the reflection-transmission energy split mode. The intelligent surface controller extracts the information required for the reflection-transmission energy split mode: time1, and the reflected beam is beam information 1. Since the transmitted beam and the reflected beam are the same under this control mode, the transmitted beam is also beam information 1, and the transmission and reflection power ratio is 1 / 2.

[0079] For another example, if the current control mode of the intelligent surface controller is the reflection-transmission time-sharing switching mode, the intelligent surface controller extracts the information required for the reflection-transmission time-sharing switching mode. Under this control mode, the working mode at a moment can only be reflection or transmission, so one of the beam information 1 and beam information 2 is configured as empty (NULL).

[0080] Example 2: The first configuration information includes multiple parameter list combinations, each parameter list combination includes multiple parameter lists, each parameter list combination corresponds to a control method, and each parameter list includes Z max Second parameter combinations, each of which includes multiple parameters and their candidate values, where Z max Is a positive integer.

[0081] In this embodiment, multiple parameter lists in the same parameter list combination may correspond to the same control method.

[0082] Referring to FIG. 3 , in step 301 , the network device sends the first configuration information to the smart surface controller.

[0083] In a specific embodiment, the multiple parameters may include time, first beam information and its operating mode, second beam information and its operating mode, and reflection-transmission power ratio. Specifically, the operating mode is selected from reflection and transmission.

[0084] For example, the i-th parameter list List i The specific form is as follows;

[0085] The i+Mth parameter list List i+M The specific form is as follows;

[0086] List of parameters i+M1 i+M1The specific form is as follows;

[0087] Among them, parameter list combination 1 includes the 1st parameter list to the i-th parameter list, and parameter list combination 1 corresponds to the reflection-transmission energy split mode, that is, the 1st parameter list to the i-th parameter list correspond to the reflection-transmission energy split mode. Parameter list combination 2 includes the i+1th parameter list to the i+Mth parameter list, and parameter list combination 2 corresponds to the reflection-transmission mode switching, that is, the i+1th parameter list to the i+Mth parameter list correspond to the reflection-transmission mode switching. Parameter list combination 3 includes the i+M+1th parameter list to the i+M1th parameter list, and parameter list combination 3 corresponds to the reflection-transmission time-sharing switching mode, that is, the i+M+1th parameter list to the i+M1th parameter list correspond to the reflection-transmission time-sharing switching mode.

[0088] In another specific embodiment, the multiple parameters include one or more of time, first beam information, second beam information, and a reflection-to-transmission power ratio. The first beam information and the second beam information each have a corresponding operating mode. For example, the default operating mode of beam information 1 is reflection, and the default operating mode of beam information 2 is transmission.

[0089] For example, the i-th parameter list List i The specific form is as follows.

[0090] The i+Mth parameter list List i+M The specific form is as follows;

[0091] List of parameters i+M1 i+M1 The specific form is as follows;

[0092] In step 302 and step 303, the smart surface controller extracts a first parameter combination corresponding to the current control mode according to the first configuration information, and controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode.

[0093] In a specific embodiment, the smart surface controller may periodically perform the above steps.

[0094] In another specific embodiment, the smart surface controller may receive second configuration information, the second configuration information including an identifier of an activated parameter list, and the first parameter combination is extracted from the activated parameter list.

[0095] For example, the current control mode of the intelligent surface controller is the reflection-transmission energy splitting mode, then the intelligent surface controller extracts the first parameter combination from the 1st parameter list to the i-th parameter list. The information extracted by the intelligent surface controller is time1, the reflected beam is beam information 1, the transmitted beam is also beam information 1, and the transmission and reflection power ratio is 1 / 2.

[0096] For another example, if the current control mode of the intelligent surface controller is the reflection-transmission time-sharing switching mode, the intelligent surface controller extracts the information required for the reflection-transmission time-sharing switching mode. Under this control mode, the working mode at a moment can only be reflection or transmission. Therefore, one of beam information 1 and beam information 2 is configured as NULL. At time 1, the reflected beam is beam index 1.

[0097] Embodiment 3: The first configuration information includes multiple parameter sets, each parameter set corresponds to a parameter, each parameter set includes multiple parameter groups, and each parameter group includes at least one candidate value of the parameter.

[0098] Referring to FIG. 4 , in step 401 , the network device sends the first configuration information to the smart surface controller.

[0099] In this embodiment, the multiple parameters may include time, first beam information, second beam information, and reflection-transmission power ratio.

[0100] For example, the specific form of one of the parameter groups in the first parameter set is as follows;

[0101] The specific form of one of the parameter groups in the second parameter set is as follows;

[0102] The specific form of one of the parameter groups in the third parameter set is as follows;

[0103] Wherein, PowerRatio represents the reflection-transmission power ratio.

[0104] In step 402, the network device sends third configuration information to the smart surface controller. The third configuration information includes pairing information between different parameter groups corresponding to various control modes, and the first parameter combination is extracted based on the first configuration information and the third configuration information.

[0105] In this embodiment, the third configuration information can be carried in downlink control information (DCI) to implement dynamic configuration of the parameters of the smart surface controller. Specifically, the DCI indicates the parameters through indexes of various parameters, such as the index of time, the index of beam information, and the index of reflection and transmission power ratio.

[0106] For example, in the reflection-transmission energy splitting mode, the pairing information between parameter groups is as follows:

[0107] In the reflection-transmission mode, the pairing information between parameter groups is as follows:

[0108] In the reflection-transmission time-sharing switching mode, the pairing information between parameter groups is as follows:

[0109] Among them, in the first parameter group representing beam information, the working mode of each beam is reflection; in the second parameter group representing beam information, the working mode of each beam is transmission.

[0110] In steps 403 and 404, the smart surface controller extracts a first parameter combination corresponding to the current control mode according to the first configuration information and the third training information, and controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode.

[0111] For example, in the reflection-transmission energy splitting mode, in the first parameter combination, the target values ​​for the time parameter range from time1 to timeN; the target values ​​for the reflection beam information parameter range from beam index 1 to beam index N; and the target values ​​for the reflection-to-transmission power ratio parameter range from power ratio1 to power ratioN. Time1, beam index 1, and power ratio 1 have a corresponding relationship and are directly indicated through the DCI. In the reflection-transmission energy splitting mode, the beam information for the transmission mode is the same as the beam information for the reflection mode.

[0112] For reflection-transmission mode switching, in the first parameter combination, the target value of the time parameter includes time1 to timeN; the target value of the reflection beam information parameter includes beam index 1 to beam index N; the target value of the transmission beam information parameter includes beam index 1 to beam index N; the target value of the reflection and transmission power ratio parameter includes power ratio1 to power ratioN, time1, beam index1, beam index1, and power ratio1 have a corresponding relationship and are directly indicated through DCI.

[0113] For reflection-transmission time-sharing switching mode, in the first parameter combination, the target values ​​for the time parameter range from time1 to timeN; the target values ​​for the reflection beam information parameter range from beam index 1 to beam index N; and the target values ​​for the transmission beam information parameter range from beam index 1 to beam index N. Time1, beam index 1, and NULL are in a corresponding relationship and are directly indicated via the DCI. In reflection-transmission time-sharing switching mode, if the reflection beam information is NULL, only the beam operating in transmission mode is operating at that moment; if the transmission beam information is NULL, only the beam operating in reflection mode is operating at that moment.

[0114] Example 4: The first configuration information includes multiple parameter lists, each parameter list includes Z max The first configuration information further includes a reflection-transmission power ratio corresponding to each parameter list, that is, the reflection-transmission power ratio values ​​are the same in the same parameter list.

[0115] In this embodiment, the third parameter combination does not include the reflection-transmission power ratio.

[0116] Please refer to FIG. 5 , in step 501 , the network device sends the first configuration information to the smart surface controller.

[0117] In a specific embodiment, the multiple parameters may include time, first beam information and its operating mode, second beam information and its operating mode, and reflection-transmission power ratio. Specifically, the operating mode is selected from reflection and transmission.

[0118] For example, the specific form of the i-th parameter list Listi is as follows, and the reflection-transmission power ratio corresponding to the i-th parameter list Listi is 1 / 2.

[0119] For example, the specific form of the i+1th parameter list Listi+1 is as follows. The reflection-transmission power ratio corresponding to the i+1th parameter list Listi+1 is 2 / 3.

[0120] In another specific embodiment, the multiple parameters include one or more of time, first beam information, second beam information, and a reflection-to-transmission power ratio. The first beam information and the second beam information each have a corresponding operating mode. For example, the default operating mode of beam information 1 is reflection, and the default operating mode of beam information 2 is transmission.

[0121] For example, the i-th parameter list List i The specific form of is shown below, where the reflection-transmission power ratio corresponding to the i-th parameter list Listi is 1 / 2.

[0122] In steps 502 and 503 , the smart surface controller extracts a first parameter combination corresponding to the current control mode according to the first configuration information, and controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode.

[0123] In a specific embodiment, the smart surface controller may periodically perform the above steps.

[0124] In another specific embodiment, the smart surface controller may receive second configuration information, the second configuration information including an identifier of an activated parameter list, and the first parameter combination is extracted from the activated parameter list.

[0125] For example, the current control mode of the intelligent surface controller is the reflection-transmission energy splitting mode. When the intelligent surface controller receives the i-th parameter list, the intelligent surface controller extracts the information required for the reflection-transmission energy splitting mode: time1, the reflected beam is beam information 1. Since the transmission beam and the reflected beam are the same under this control mode, the transmission beam is also beam information 1, and the transmission and reflection power ratio is 1 / 2 of the transmission and reflection power ratio corresponding to the i-th parameter list.

[0126] Example 5: The first configuration information includes multiple parameter lists, each parameter list includes Z max third parameter combinations, each of which includes multiple parameters and candidate values ​​thereof.

[0127] Compared with the second parameter combination, the third parameter combination does not include the reflection-transmission power ratio.

[0128] Referring to FIG. 6 , in step 601 , the network device sends the first configuration information to the smart surface controller.

[0129] The format of the parameter list in this embodiment of the present invention is the same as that in Example 4 and will not be repeated here.

[0130] In step 602, the network device sends a power control parameter to the smart surface controller. The power control parameter includes a reflection-transmission power ratio.

[0131] In this embodiment, the reflection-transmission power ratio and other parameters of the smart surface controller can be configured independently.

[0132] In steps 603 and 604, the smart surface controller extracts a first parameter combination corresponding to the current control mode according to the first configuration information and the power control parameter, and controls the reflection and / or transmission of electromagnetic waves according to the first parameter combination under the current control mode.

[0133] In a specific embodiment, the smart surface controller may periodically perform the above steps.

[0134] In another specific embodiment, the smart surface controller may receive second configuration information, the second configuration information including an identifier of an activated parameter list, and the first parameter combination is extracted from the activated parameter list.

[0135] For example, if the smart surface controller's current control mode is reflection-transmission energy splitting, and it receives the i-th parameter list, it extracts the information required for reflection-transmission energy splitting: time 1, and the reflected beam is beam information 1. Because the transmitted and reflected beams are identical in this control mode, the transmitted beam is also beam information 1. The ratio of transmitted to reflected power is controlled and adjusted using the power control parameter.

[0136] In embodiment 6, the first configuration information includes multiple parameter sets, each parameter set corresponds to a parameter, each parameter set includes multiple parameter groups, each parameter group includes at least one candidate value of the parameter, and the parameter set does not correspond to the reflection-transmission power ratio.

[0137] In this embodiment, the network device sends third configuration information to the smart surface controller. The third configuration information includes pairing information between different parameter groups corresponding to various control modes, and the first parameter combination is extracted based on the first configuration information and the third configuration information.

[0138] In this embodiment, the third configuration information can be carried in the DCI to implement dynamic configuration of the parameters of the smart surface controller. Specifically, the DCI indicates the parameters through indexes, such as the time index, the beam information index, and the reflection and transmission power ratio index.

[0139] For example, in the reflection-transmission energy splitting mode, the pairing information between parameter groups is as follows:

[0140] In the reflection-transmission mode, the pairing information between parameter groups is as follows:

[0141] In the reflection-transmission time-sharing switching mode, the pairing information between parameter groups is as follows:

[0142] Compared with Example 3, the parameter set configured in Example 6 does not include a parameter group for the reflection-transmission power ratio.

[0143] In this case, the network device can indicate and adjust the reflection-transmission power ratio to the smart surface controller through the power control parameters.
