Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a signal measurement and transmission method, apparatus, terminal, network equipment and forwarding node. Background Technology

[0002] High-frequency bands have short wavelengths, poor reflection and diffraction properties, and significant path loss, typically requiring multi-beam communication coverage. To ensure user communication quality, it is necessary to measure and report the quality of the transmit and receive beams, and to switch the optimal transmit and receive beam pair in a timely manner according to channel changes. However, in wireless communication systems that relay base station signals through relay nodes (e.g., Reconfigurable Intelligent Surfaces (RIS)), an additional hop is added between the base station and the user equipment (UE, also known as the terminal). The link quality of the relay node also affects terminal communication. Therefore, how to achieve terminal measurement of the relay node's beam is a problem that urgently needs to be solved.

[0114] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0115] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein may be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0116] In this application's embodiments, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this application's embodiments, the term "multiple" refers to two or more, and other quantifiers are similar.

[0117] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0118] The embodiments of this application are described below with reference to the accompanying drawings. The signal measurement, transmission method, apparatus, terminal, network equipment, and forwarding node provided in the embodiments of this application can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G NR system is merely an example and not intended to be limiting.

[0119] See Figure 1 , Figure 1 This is a structural diagram of a network system that can be applied to the embodiments of this application, such as... Figure 1As shown, the system includes a user terminal 11, a base station 12, and a RIS 13. The base station 12 transmits signals to the user terminal 11 through the RIS 13. The user terminal 11 can be user equipment (UE), such as a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that the specific type of user terminal 11 is not limited in this embodiment. The base station 12 can be a 5G or later version base station (e.g., gNB, 5G NR NB), or a base station in other communication systems, also referred to as a node B. It should be noted that this embodiment only uses a 5G base station as an example, but the specific type of base station 12 is not limited.

[0120] First, based on the technical solution provided in this application, some technical terms that may be involved will be introduced.

[0121] like Figure 1 In the RIS-based wireless communication link shown, assume the base station has M beams, the RIS has L beams (assuming the RIS has the same number of transmit and receive beams), and the UE has N beams. Then, the radio connection from the base station to the UE has a total of M*L*L*N transmit / receive (TX-RX) beam pairs. Since the number of TX / RX beams in the millimeter-wave band is typically large, efficient beam measurement and reporting procedures are crucial for achieving sufficient coverage while ensuring low overhead and UE complexity.

[0122] In existing single-hop systems, for each TX beam, the measurement quality of a beam pair needs to be reported (e.g., the best RX beam for a given TX beam). The best RX beam is obtained through beam measurement at the UE and stored in the UE's memory, but does not need to be reported. Upon subsequent transmission to the terminal, the base station indicates the index of the selected TX beam to the terminal. The terminal can use the latest best RX beam of the indicated TX beam (stored in the terminal's memory during beam measurement) to receive the signal. Secondly, among M candidate TX beams, the quality and / or index of K TX beams can be reported, where 1 ≤ K ≤ M. If K = 1, the UE can report the best TX beam index (without associated beam quality) as a recommendation to the base station for downlink (DL) beamforming. If K > 1, the UE can report the metrics (e.g., the best K beams) and their measurement quality (whether relative or absolute) of the K selected TX beams to the base station. The network then decides how to use the reported K beams for DL ​​transmission. For example, if a base station has only one Tx panel, it can compare the reported quality of the Tx beams and select one for DL ​​transmission. If a base station has multiple Tx panels, it can use different beams on different panels for transmission.

[0123] Beam measurement metrics can include Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Channel State Information (CSI). Different metrics lead to varying UE complexities and may be suitable for different scenarios. For example, RSRP measurement is relatively simple and energy-efficient. It facilitates the rapid measurement of a large number of beams, which is useful for initial beam acquisition. CSI measurement is more complex but provides more accurate beam information, which can be used for beam refinement within a small group of candidate beams. CSI-based beam reporting is also faster because it integrates beam training and link adaptation in one step, allowing the base station to quickly schedule data after receiving the beam report. On the other hand, RSRP- or RSRQ-based beam reporting requires a two-step procedure (e.g., beam training, and CSI reporting based on the Reference Signal (RS) configuration from the beam training results), which increases scheduling latency.

[0124] The beam measurement process described above only applies to the single-hop link from the base station to the UE. The measurement and reporting objects are mainly the transmit and receive beams on the base station side; the transmit and receive beams on the UE side are only measured but not reported. For a two-hop link based on RIS wireless communication, taking the following line as an example, if the UE directly measures the signal from the base station, it can only directly measure the overall equivalent channel information of the base station-RIS-UE, obtaining the beam measurement results of the transmit beam used by the base station. It cannot measure the beam of the RIS-UE segment. Due to the movement of the UE, the channel from RIS to UE constantly changes, and the measurement and reporting of the RIS transmit and receive beams also needs to be considered. Since the RIS transmit and receive beams are controlled by a set of RIS phase shift matrices, i.e., one RIS phase shift matrix corresponds to one RIS transmit and receive beam pair, once the RIS phase shift matrix is ​​determined, the direction of the RIS receive beam and the direction of the transmit beam are both determined (under far-field conditions). Therefore, the RIS receive beam and transmit beam are referred to as RIS beams.

[0125] Based on the analysis, embodiments of this application provide a signal measurement and transmission method, apparatus, terminal, network device, and forwarding node to achieve beam measurement of the forwarding node.

[0126] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0127] like Figure 2 As shown, this application embodiment provides a measurement reporting method, executed by a terminal, including:

[0128] Step S201: Receive the modulated signal sent by the forwarding node;

[0129] The modulation signal is obtained by the forwarding node modulating the network device measurement signal, and the modulation signal includes the network device measurement signal and the forwarding node measurement signal, wherein the forwarding node measurement signal corresponds to the beam of the forwarding node;

[0130] It should be noted that the forwarding node modulates the network device's measurement signal and adds it to the forwarding node's measurement signal, enabling the terminal to measure the forwarding node's beam based on the forwarding node's measurement signal.

[0131] Step S202: Based on the modulation signal, obtain the target measurement result, which includes the beam quality corresponding to the beam of the forwarding node;

[0132] It should be noted that in this embodiment, the forwarding node is located between the network device and the terminal and is responsible for forwarding the communication signals between the network device and the terminal. That is, the communication architecture of this embodiment is that the network device sends a signal to the forwarding node, and the forwarding node sends a reflected signal to the terminal. Optionally, the forwarding node in this embodiment can be a RIS, a network-controlled repeater (NCR), a relay device, or other devices that can perform signal forwarding.

[0133] Optionally, the network device measurement signal in this embodiment can be a reference signal, such as a channel state information reference signal (CSI-RS); or a pilot signal, such as a demodulation reference signal (DMRS); the forwarding node measurement signal can be a reference signal, a rank indicator (RI), or a predefined sequence (e.g., a ZC sequence, a Gold sequence, etc.).

[0134] It should be noted that when the measurement signals of the forwarding nodes are predefined sequences (also called measurement sequences), each sequence corresponds to a beam of a forwarding node. Each beam of the forwarding node array within a predefined service area (e.g., a cell) has a one-to-one corresponding sequence. The sequences corresponding to the beams of all forwarding nodes form a sequence set, which is known to the network devices, forwarding nodes, and the terminal side. It should also be noted that each beam of each forwarding node has unique identification. Forwarding node arrays in adjacent cells or service areas use different sequence sets to ensure that the beams of forwarding nodes in adjacent cells or control nodes can be uniquely identified.

[0135] Optionally, the network device measurement signal and the network device beam (also referred to as the network device beam) are in one-to-one correspondence, and the forwarding node measurement signal and the forwarding node beam (also referred to as the forwarding node beam) are in one-to-one correspondence.

[0136] It should be noted that in this embodiment of the application, the measurement signal of the network device is modulated by the forwarding node so as to add the measurement signal of the forwarding node to the modulated signal sent by the forwarding node to the terminal, thereby enabling the terminal to measure the beam of the forwarding node.

[0137] Optionally, in one implementation, the network device needs to send a network device measurement signal to the forwarding node. After receiving the network device measurement signal, the forwarding node needs to modulate the measurement signal to obtain a modulated signal, which includes both the network device measurement signal and the forwarding node's measurement signal. Optionally, the forwarding node can modulate the network device measurement signal by amplitude modulation or phase modulation.

[0138] Optionally, after receiving the modulated signal sent by the forwarding node, the terminal needs to demodulate the modulated signal to obtain the measurement signal of the forwarding node. Optionally, the terminal can demodulate the measurement signal of the forwarding node through a filter, coherent or non-coherent demodulation, etc. After obtaining the measurement signal of the forwarding node, the terminal can measure the measurement signal of the forwarding node to obtain the beam quality corresponding to the beam of the forwarding node.

[0139] Optionally, after demodulating the modulated signal, the terminal can also obtain the network device measurement signal. That is, by demodulating the modulated signal, the terminal can obtain the network device measurement signal and the forwarding node measurement signal respectively. If the terminal only measures the forwarding node measurement signal, it can only obtain the beam quality corresponding to the beam of the forwarding node. If the terminal measures the network device measurement signal and the forwarding node measurement signal respectively, it can obtain the beam quality corresponding to the beam of the network device and the beam quality corresponding to the beam of the forwarding node respectively.

[0140] Optionally, in one implementation, the forwarding node modulates the measurement signal of the network device to obtain the modulated signal. Specific implementations include:

[0141] The control matrix is ​​switched at a preset time point to modulate the received measurement signal from the network device to obtain a modulated signal.

[0142] It should be noted that since different control matrices correspond to different beam directions and measurement signals corresponding to the beams, switching the control matrix can modulate the measurement signal of the forwarding node into the measurement signal of the network device to obtain the modulated signal.

[0143] Optionally, in one implementation, the control matrix is ​​switched at a preset time point to modulate the received measurement signal from the network device to obtain a modulated signal, including:

[0144] Step S11: Obtain control configuration information, wherein the control configuration information includes a control matrix, or the control configuration information includes a reflection coefficient matrix and the measurement signal of the forwarding node;

[0145] Optionally, the control configuration information is typically transmitted from the network device to the forwarding node. For example, the network device can send the control configuration information to the forwarding node via the air interface, or the network device can transmit the control configuration information to the forwarding node via a wired network.

[0146] Step S12: According to the control configuration information, switch the control matrix at a preset time point to modulate the received network device measurement signal to obtain a modulated signal;

[0147] The control matrix is ​​determined by the reflection coefficient matrix and the measurement signal of the forwarding node.

[0148] It should be noted that, in order to achieve modulation of the forwarding node, the network device usually sends modulation configuration information to the forwarding node. Optionally, if the modulation configuration information only includes the modulation matrix, it means that the calculation of the modulation matrix is ​​implemented by the network device, and the forwarding node only needs to directly receive the modulation matrix sent by the network device and use it. This can avoid the delay and power consumption of the forwarding node in calculating the modulation matrix. If the modulation configuration information includes the reflection coefficient matrix and the measurement signal of the forwarding node, then the forwarding node needs to calculate the modulation matrix and then use the calculated modulation matrix.

[0149] It should be noted that the reflection coefficient matrix in this embodiment is used to represent the beam of the forwarding node. One reflection coefficient matrix represents the beam of one forwarding node, corresponding to the incident and reflected signal directions of a forwarding node array. This reflection coefficient matrix can be determined by the network device based on prior information such as network deployment, channel information reported by the terminal, and / or beam information. The measurement signal of the forwarding node corresponds to the beam of the forwarding node; that is, one measurement signal of the forwarding node represents the measurement information of one beam of the forwarding node. Typically, the measurement signal of the forwarding node corresponds to the beam index of the forwarding node.

[0150] For example, taking the relay node as RIS and the relay node's beam as the RIS beam as an example, one possible process for generating the control matrix (modulated by phase modulation) is as follows:

[0151] A RIS array has two RIS beams, and two phase modulations are used to represent the beam indices of the two RIS beams (i.e., the added modulation information used to represent the RIS measurement signal). The generation process of the corresponding control matrix for the RIS is as follows: Figure 3 As shown.

[0152] It should be noted that after the terminal performs measurement to obtain beam quality, it can also report beam-related information so that network devices can obtain the beam status of the forwarding nodes and select the better beam for signal forwarding. Optionally, in one implementation, after obtaining the target measurement result based on the modulation signal, the method further includes:

[0153] Based on the target measurement results, measurement reporting information is sent to the network device. The measurement reporting information includes at least one of the following: beam quality corresponding to the beam of the forwarding node, and beam indication information corresponding to the beam of the forwarding node.

[0154] It should be noted that when only the beam of the forwarding node is measured, the measurement report information sent by the terminal to the network device only includes the relevant information of the forwarding node's beam, that is, the beam quality and / or the beam indication information of the forwarding node's beam. If the terminal also measures the signal of the network device, the terminal also needs to send the relevant information of the network device's beam to the network device. For example, the relevant information of the network device's beam includes the beam quality and / or the beam indication information of the network device's beam.

[0155] Optionally, since a forwarding node can use one beam or multiple beams to transmit modulated signals, when only one beam is used, the terminal obtains the beam quality of that single beam, and can report only that beam quality. If multiple beams are used, the terminal obtains the beam quality of multiple beams. In this case, the terminal can select the optimal beam to report. Optionally, the terminal can report the beam quality and beam indication information of the optimal beam, or the terminal can report only the beam indication information of the optimal beam. Alternatively, if the terminal obtains multiple beam qualities, the terminal can select the optimal multiple beams to report. Optionally, the terminal can report the beam quality and beam indication information of the optimal multiple beams, or the terminal can report the beam indication information of the optimal multiple beams.

[0156] For example, if the measurement reporting information only includes the beam quality corresponding to the beam of the forwarding node, it can be understood that the forwarding node uses only one beam to transmit the modulated signal. Since which beam the forwarding node uses for transmission is configured in advance, after the terminal reports the beam quality corresponding to the beam of the forwarding node through the measurement reporting information, the network device can know which beam the beam quality corresponds to.

[0157] For example, if the measurement and reporting information only includes the beam indication information corresponding to the beam of the forwarding node, it can be understood that the forwarding node usually uses multiple beams to transmit modulated signals. The terminal can determine the beam quality of multiple beams by measurement. The terminal can choose the beam with the best beam quality to report. After the terminal reports the beam indication information of the best beam through the measurement and reporting information, the network device can know which beam has the best beam quality.

[0158] For example, when the measured and reported information includes the beam quality and beam indication information corresponding to the beam of a forwarding node, in one scenario, it can be understood that the forwarding node uses one beam to transmit modulated signals. To clarify the correspondence between the beam and its quality, the terminal needs to report both the beam quality and beam indication information simultaneously. In another scenario, it can be understood that the forwarding node typically uses multiple beams to transmit modulated signals. The terminal can determine the beam quality of each beam through measurement, and can choose the beam with the best quality to report. The terminal can simultaneously report both the beam quality and the beam indication information corresponding to the forwarding node's beam. After receiving information from the terminal, the network device can determine which beam is the optimal beam and its corresponding beam quality. Alternatively, a forwarding node typically uses multiple beams to transmit modulated signals. The terminal can determine the beam quality of each beam through measurement. The terminal can then select several beams with superior beam quality to report. In this case, the terminal needs to simultaneously report the beam quality and beam indication information of the superior beams. After receiving the information from the terminal, the network device can identify the superior beams and their corresponding beam qualities. The network device can then select the optimal beam from these beams for signal transmission.

[0159] Optionally, in one implementation, the beam indication information includes at least one of the following:

[0160] A11, Beam Marker;

[0161] It should be noted that the beam identifier can be a beam index or a beam number.

[0162] A12, Measurement signal identifier of the relay node corresponding to the beam;

[0163] It should be noted that since each beam corresponds to a different relay node measurement signal, the relay node measurement signal can be used for beam indication. Optionally, the relay node measurement signal identifier can be a measurement signal index, an identifier of the sequence corresponding to the measurement signal, or a sequence corresponding to the measurement signal.

[0164] For example, the beam indication information only includes the beam identifier. By indicating the beam identifier, the network device can clearly know which beam the terminal is measuring. This is applicable to scenarios where a beam identifier has been explicitly configured for the terminal.

[0165] For example, the beam indication information only includes the forwarding node measurement signal identifier corresponding to the beam. It should be noted that since the forwarding node measurement signal corresponds one-to-one with the beam, after the network device obtains the forwarding node measurement signal identifier, it can determine which beam corresponds to it based on the forwarding node measurement signal identifier. This situation applies to cases where the beam identifier is not explicitly configured for the terminal. The terminal can determine what the measured forwarding node measurement signal is by demodulating the modulated signal.

[0166] For example, the beam indication information includes the beam identifier and the corresponding forwarding node measurement signal identifier. The direct indication of these two types of information enables network devices to quickly determine what the forwarding node measurement signal being measured by the terminal is and which beam it is measuring, without the need for the network device to determine based on the correspondence between the beam and the forwarding node measurement signal.

[0167] It is important to note that since measurement signals are usually composed of sequences, and different measurement signals correspond to different sequences, the measurement signal can be indicated by the sequence.

[0168] Optionally, in one implementation, the modulation signal transmitted by the receiving and forwarding node includes:

[0169] Step S21: Obtain configuration information;

[0170] Optionally, the configuration information includes at least one of the following:

[0171] B11. At least one measurement opportunity;

[0172] B12, the beam identifier of the beam of the forwarding node;

[0173] B13. The measurement signal identifier of the forwarding node corresponding to the beam of the forwarding node.

[0174] It should be noted that this configuration information must typically include the measurement timing, which indicates the time unit position for transmitting the measurement signal. By informing the terminal of the beam information of the forwarding node, the terminal can know which beams are transmitting signals.

[0175] Optionally, B12 and B13 are optional. When there are at least two measurement opportunities (or time units), the terminal can determine which beams transmitted signals based on the joint detection results of multiple measurement opportunities. It should be noted that when there are at least two measurement opportunities, the same network device's measurement signal will be transmitted in multiple time units (e.g., the same Channel State Information Reference Signal (CSI-RS) resource is configured in multiple Channel State Information (CSI) resource settings or multiple CSI resource sets), and the same forwarding node measurement signal is added to multiple time units. The terminal receives signals in multiple time units according to predefined rules or network device instructions, and performs joint detection based on the signals from multiple time units to obtain beam quality.

[0176] Optionally, when there is only one measurement opportunity, B12 and / or B13 configuration is usually required so that the terminal can know which beams are being measured.

[0177] Optionally, the configuration information can be sent to the terminal by the network device or it can be agreed upon by a protocol; and the different contents contained in the configuration information can be obtained in different ways. For example, B11 is obtained through a protocol-defined method, while B12 and / or B13 are obtained through network device configuration. Optionally, when the configuration information is configured by the network device, the network device can send the configuration information through DCI.

[0178] For example, if the configuration information includes a measurement timing and the beam identifier of the forwarding node's beam, the terminal receives the modulated signal at the measurement timing indicated by the configuration information, and then measures the measurement signal of the forwarding node obtained by demodulation. This allows the terminal to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information. By configuring the measurement timing and the beam identifier, the terminal can clearly know which beams are being measured.

[0179] For example, if the configuration information includes a measurement timing, the beam identifier of the forwarding node's beam, and the forwarding node measurement signal identifier corresponding to the forwarding node's beam, the terminal receives the modulated signal at the measurement timing indicated by the configuration information, and then measures the forwarding node measurement signal obtained through demodulation. This allows the terminal to obtain the beam quality corresponding to the forwarding node's beam indicated by the configuration information. By configuring the measurement timing, beam identifier, and forwarding node measurement signal identifier, the terminal can clearly know which beams are being measured and determine what the forwarding node measurement signal corresponding to the measured beam is.

[0180] For example, when the configuration information includes multiple measurement opportunities, the terminal receives the modulated signal at the measurement opportunity indicated by the configuration information, and then performs joint measurement on the forwarding node measurement signals obtained by demodulation in multiple measurement opportunities. This allows the beam quality corresponding to the specific beam of the forwarding node to be obtained. In this way, there is no need to configure the beam and the forwarding node measurement signals, which can save the signaling overhead of the configuration information.

[0181] For example, when the configuration information includes multiple measurement opportunities and the beam identifier of the forwarding node's beam, the terminal receives the modulated signal at the measurement opportunity indicated by the configuration information, and then performs joint measurement on the forwarding node measurement signals obtained by demodulation in multiple measurement opportunities. This allows the terminal to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information. In this way, the terminal does not need to determine which beams are being measured separately based on the joint measurement, which can reduce the terminal's measurement overhead and improve the speed of beam quality acquisition.

[0182] For example, when the configuration information includes multiple measurement opportunities and the forwarding node measurement signal identifier corresponding to the beam of the forwarding node, the terminal receives the modulated signal at the measurement opportunity indicated by the configuration information, and then performs joint measurement on the forwarding node measurement signals obtained by demodulation in multiple measurement opportunities. This allows the beam quality corresponding to the beam of the forwarding node indicated by the configuration information to be obtained. Moreover, the forwarding node measurement signal identifier and the beam are in one-to-one correspondence. Through the correspondence between the forwarding node measurement signal identifier and the beam, it is possible to directly determine which beams are being measured, thereby reducing the measurement overhead of the terminal and improving the acquisition speed of beam quality.

[0183] For example, when the configuration information includes multiple measurement opportunities, the beam identifier of the forwarding node's beam, and the forwarding node measurement signal identifier corresponding to the forwarding node's beam, the terminal receives the modulated signal at the measurement opportunity indicated by the configuration information. Then, it performs joint measurement on the forwarding node measurement signals obtained through demodulation at multiple measurement opportunities to obtain the beam quality corresponding to the forwarding node's beam indicated by the configuration information. In this method, the terminal does not need to separately determine which beams are being measured based on the joint measurement, and the forwarding node measurement signal identifier corresponds one-to-one with the beam. The terminal can directly determine what forwarding node measurement signal is used to measure the beam being measured through the indication of the configuration information. This method can reduce the terminal's measurement overhead and improve the speed of beam quality acquisition.

[0184] Step S22: At the measurement timing indicated by the configuration information, receive the modulated signal transmitted by the forwarding node through at least one beam;

[0185] It should be noted that by obtaining the configuration information, the terminal can know how the forwarding node transmits the modulated signal, thereby improving the accuracy of the terminal receiving the modulated signal.

[0186] In summary, this application proposes a method for beam measurement and reporting of a forwarding node. While the forwarding node reflects the network device measurement signal transmitted by the network device, it modulates the network device measurement signal using the forwarding node (e.g., by adding a fixed phase or overall amplitude modulation). Then, it uses the modulated information (i.e., the forwarding node measurement signal) to measure the beam of the forwarding node and obtain the measurement result. This enables the terminal to measure the beam of the forwarding node, facilitates the network device to control the beam of the forwarding node, and improves the communication reliability of the terminal.

[0187] The following describes the specific application of this application embodiment, taking the communication between the base station and the terminal via RIS as an example.

[0188] First, it should be noted that the signal received by the terminal may fall into one of the following three categories:

[0189] A. The terminal detects the measurement signal from the base station and the additional RIS measurement signal after RIS modulation.

[0190] This situation indicates that the terminal can receive signals sent by the base station and relayed by RIS.

[0191] B. The terminal detects additional information (RIS beam indication) after RIS modulation of an unknown signal (signal from other environmental signal sources). In this case, it can be understood that the terminal only detects the RIS measurement signal.

[0192] This situation indicates that the terminal is within the coverage area of ​​the RIS, but the RIS is not forwarding any signals sent by the base station.

[0193] C. The terminal detects the measurement signal sent by the base station, but does not detect the additional RIS measurement signal after RIS modulation, that is, the terminal does not detect the RIS measurement signal.

[0194] This situation indicates that the terminal can directly receive the base station's signal without the need for RIS forwarding.

[0195] It should also be noted that when the signal received by the terminal contains both A and C, it means that the terminal can receive signals from both the direct link and the reflected link (RIS forwarding) at the same time.

[0196] The embodiments of this application may include the following application scenarios:

[0197] Application Scenario 1: Measurement Reporting Based on a Single Time Unit

[0198] The terminal reports measurements at the measurement time indicated by the base station, based on the configuration information configured by the base station (which includes the base station beam index, RIS beam index, and measurement timing (also known as reception timing)). The specific process is as follows:

[0199] Step 11: The terminal receives configuration information (e.g., DCI) sent by the base station and obtains the base station beam index, RIS beam index, and measurement timing.

[0200] Step 12: The terminal receives the modulation signal at the measurement time according to the configuration information, and performs the detection of the base station measurement signal and the RIS measurement signal according to the beam index indicated by the base station to obtain the corresponding beam quality (e.g., the beam RSRP).

[0201] Step 13: The terminal reports beam information (beam quality and / or beam identifier) ​​to the base station according to the predefined beam reporting criteria.

[0202] A possible beam measurement reporting process is illustrated as follows: Figure 4 As shown, the base station and the terminal transmit and receive downlink control information in time unit 1, and the base station, RIS and the terminal transmit and detect signals in time unit 2.

[0203] It should be noted that the above process can be used for multi-beam or single-beam measurement and reporting. Different measurement processes can define different beam reporting criteria, or they can define the same reporting criteria. For example:

[0204] Single-beam measurements only report beam quality;

[0205] Multi-beam measurements report one or more beam identifiers that meet predefined rules, such as the beam with the highest RSRP.

[0206] Multi-beam measurements report one or more beam identifiers and beam qualities that meet predefined rules.

[0207] Main implementation on the RIS side:

[0208] The RIS switches the control matrix at a preset time point according to the control configuration information configured by the base station, that is, it modulates the base station measurement signal incident on the RIS array, obtains the modulated signal, and sends it to the terminal.

[0209] The main implementation of a base station:

[0210] The base station sends configuration information to the terminal, instructing the terminal to perform beam measurement at the appropriate time and report the measurement.

[0211] The base station determines the control matrix based on prior information such as network deployment, channel information and / or beam information reported by the UE, and instructs the RIS to switch the control matrix at a preset time point; or, the base station sends the reflection coefficient matrix and RIS measurement signal to the terminal.

[0212] Application Scenario 2: Measurement Reporting Based on Multiple Time Units

[0213] Starting from the nth transmission time unit (e.g., n Orthogonal frequency division multiplex (OFDM) symbols) after sending the control configuration information, the base station transmits the same base station measurement signal for M consecutive time units.

[0214] Starting from the nth transmission time unit (e.g., n OFDM symbols) after receiving the control configuration information, the RIS transmits a modulated signal every L time units, and continuously transmits M identical modulated signals.

[0215] Based on the configuration information sent by the base station, the terminal receives modulated signals at multiple predefined measurement opportunities to perform joint measurements and report. The specific process is as follows:

[0216] Step 21: The terminal receives configuration information (e.g., DCI) sent by the base station to obtain the measurement opportunity.

[0217] Step 22: The terminal receives the modulation signal according to the acquired measurement timing, and performs detection together with multiple RIS measurement signals in the modulation signal to determine the beam quality (e.g., the RSRP of the beam) of the RIS beam. It also performs detection together with multiple base station measurement signals in the modulation signal to determine the beam quality (e.g., the RSRP of the beam) of the base station beam.

[0218] Step 23: The terminal reports beam information (beam quality information and / or beam identifier) ​​to the base station according to the predefined beam reporting criteria.

[0219] A possible multi-time-unit joint beam measurement reporting process is as follows: Figure 5 As shown. After receiving all M=3 modulated signals, the terminal performs joint detection on the base station measurement signal and the RIS measurement signal in all 3 modulated signals to determine the beam index and beam quality of the RIS beam and the beam index and beam quality of the base station beam.

[0220] Application Scenario 3: The terminal identifies the received signal as a direct signal transmitted by the base station.

[0221] The terminal reports measurements at the designated measurement time indicated by the base station, based on the configuration information sent by the base station. The specific process is as follows:

[0222] Step 31: The terminal receives configuration information (e.g., DCI) sent by the base station and obtains the base station beam index and measurement timing.

[0223] Step 32: The terminal receives the base station measurement signal (which has a one-to-one correspondence with the beam index) during the measurement. It performs measurement signal detection according to the beam index indicated by the base station and obtains only the base station beam index and the corresponding beam quality.

[0224] Step 33: The terminal determines that the received signal is a signal directly transmitted by the base station, and only reports the beam quality and / or beam identifier of the base station beam to the base station.

[0225] Application Scenario 4: The terminal identifies the received signal as a RIS forwarding signal.

[0226] The terminal reports measurements at the designated measurement time indicated by the base station, based on the configuration information sent by the base station. The specific process is as follows:

[0227] Step 41: The terminal receives configuration information (e.g., DCI) sent by the base station and obtains the measurement timing and RIS beam index.

[0228] Step 42: The terminal receives the modulated signal (which has a one-to-one correspondence with the beam index) during the measurement. It performs signal detection according to the beam index indicated by the base station and obtains only the RIS beam index and the corresponding beam quality.

[0229] Step 43: The terminal determines that the received signal is a RIS forwarding signal and only reports the beam quality and / or beam identifier of the RIS beam to the base station.

[0230] Application Scenario 5

[0231] The terminal receives signals during measurement according to the base station configuration. It detects a modulated signal containing the RIS measurement signal and a signal containing only the base station measurement signal but without the RIS measurement signal. The terminal can choose to report the beam information (including beam index and / or beam quality) of the stronger link based on the measured beam quality, or it can report the information of both links, allowing the base station to decide which link to use for signal transmission.

[0232] In summary, the embodiments of this application solve the problem that in RIS-based wireless communication systems, the lack of signal processing capabilities of the RIS makes it difficult to measure and report RIS beams. The beam measurement and reporting method proposed in the embodiments of this application can solve the problem of RIS beam measurement and reporting with lower overhead and complexity.

[0233] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0234] The terminal involved in the embodiments of this application, also known as a terminal device, can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application does not limit the terminology.

[0235] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0236] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0237] like Figure 6 As shown, this application embodiment provides an information transmission method applied to a forwarding node, including:

[0238] Step S601: Modulate the received network device measurement signal to obtain a modulated signal, wherein the modulated signal includes: the network device measurement signal and the forwarding node measurement signal, and the forwarding node measurement signal corresponds to the beam of the forwarding node;

[0239] Optionally, the forwarding node in the embodiments of this application can be a device capable of signal forwarding, such as a RIS or NCR.

[0240] The network device measurement signal in this embodiment can be a reference signal, such as a channel state information reference signal (CSI-RS); or a pilot signal, such as a demodulation reference signal (DMRS); the forwarding node measurement signal can be a reference signal, a rank indicator (RI), or a predefined sequence (e.g., a ZC sequence).

[0241] Step S602: Send the modulated signal to the terminal;

[0242] It should be noted that in this embodiment of the application, the measurement signal of the network device is modulated by the forwarding node so as to add the measurement signal of the forwarding node to the modulated signal sent by the forwarding node to the terminal, thereby enabling the terminal to measure the beam of the forwarding node.

[0243] Optionally, in one implementation, modulating the received network device measurement signal to obtain a modulated signal includes:

[0244] The control matrix is ​​switched at a preset time point to modulate the received measurement signal from the network device to obtain a modulated signal.

[0245] It should be noted that since different control matrices correspond to different beam directions and measurement signals corresponding to the beams, switching the control matrix can modulate the measurement signal of the forwarding node into the measurement signal of the network device to obtain the modulated signal.

[0246] Optionally, in one implementation, the step of switching the control matrix at a preset time point to modulate the received network device measurement signal to obtain a modulated signal includes:

[0247] Obtain control configuration information, wherein the control configuration information includes a control matrix, or the control configuration information includes a reflection coefficient matrix and the measurement signal of the forwarding node;

[0248] Optionally, the control configuration information is typically transmitted from the network device to the forwarding node. For example, the network device can send the control configuration information to the forwarding node via the air interface, or the network device can transmit the control configuration information to the forwarding node via a wired network.

[0249] According to the control configuration information, the control matrix is ​​switched at a preset time point to modulate the received network device measurement signal to obtain a modulated signal;

[0250] The control matrix is ​​determined by the reflection coefficient matrix and the measurement signal of the forwarding node.

[0251] It should be noted that, in order to achieve modulation of the forwarding node, the network device usually sends modulation configuration information to the forwarding node. Optionally, if the modulation configuration information only includes the modulation matrix, it means that the calculation of the modulation matrix is ​​implemented by the network device, and the forwarding node only needs to directly receive the modulation matrix sent by the network device and use it. If the modulation configuration information includes the reflection coefficient matrix and the measurement signal of the forwarding node, then the forwarding node needs to calculate the modulation matrix and then use the calculated modulation matrix.

[0252] It should be noted that the reflection coefficient matrix in this embodiment is used to represent the beam of a forwarding node. One reflection coefficient matrix represents the beam of a forwarding node, corresponding to the incident and reflected signal directions of a forwarding node array. This reflection coefficient matrix can be determined by the network device based on prior information such as network deployment and / or channel information and / or beam information reported by the terminal. The forwarding node measurement signal corresponds to the beam; that is, one forwarding node measurement signal represents the measurement information of one beam of the forwarding node. Typically, the forwarding node measurement signal corresponds to the beam index.

[0253] It should be noted that by controlling the transmission of configuration information, the forwarding nodes can accurately perform modulation, thereby improving the accuracy of modulation.

[0254] It should be noted that all descriptions of forwarding nodes in the above embodiments are applicable to the embodiments of this signal transmission method and can achieve the same technical effect, so they will not be repeated here.

[0255] like Figure 7 As shown, this application provides an information transmission method applied to a network device, including:

[0256] Step S701: Send network device measurement signals to the forwarding node;

[0257] It should be noted that the measurement signal of this network device corresponds to the beam of the network device.

[0258] Step S702: Receive measurement reporting information sent by the terminal. The measurement reporting information includes at least one of the following: beam quality corresponding to the beam of the forwarding node, and beam indication information corresponding to the beam of the forwarding node.

[0259] The measurement reporting information is sent based on the target measurement result, which is obtained by the terminal according to the modulation signal sent by the forwarding node. The target measurement result includes the beam quality corresponding to the beam of the forwarding node.

[0260] The modulation signal is obtained by the forwarding node modulating the network device measurement signal. The modulation signal includes the network device measurement signal and the forwarding node measurement signal, and the forwarding node measurement signal corresponds to the beam of the forwarding node.

[0261] Optionally, in one implementation, the method further includes:

[0262] Send configuration information to the terminal, the configuration information including at least one of the following:

[0263] At least one measurement opportunity;

[0264] The beam identifier of the beam of the forwarding node;

[0265] The relay node's beam corresponds to the relay node's measurement signal identifier.

[0266] Sending configuration information to the terminal via network devices enables real-time adjustments to the configuration information, thus providing flexibility in configuration.

[0267] Optionally, in one implementation, the method further includes:

[0268] Send control configuration information to the forwarding node, the control configuration information including a control matrix, or the control configuration information including a reflection coefficient matrix and the measurement signal of the forwarding node;

[0269] The control matrix is ​​determined by the reflection coefficient matrix and the measurement signal from the forwarding node.

[0270] It should be noted that by controlling the transmission of configuration information, the forwarding nodes can accurately perform modulation, ensuring the accuracy of the modulated signal.

[0271] Optionally, in one implementation, the beam indication information includes at least one of the following:

[0272] Beam identifier; it should be noted that the beam identifier can be a beam index or a beam number.

[0273] The relay node measurement signal identifier corresponding to the beam; it should be noted that since each beam corresponds to a different relay node measurement signal, the relay node measurement signal can be used to indicate the beam. Optionally, the relay node measurement signal identifier can be a measurement signal index, an identifier of the sequence corresponding to the measurement signal, or a sequence corresponding to the measurement signal.

[0274] It should be noted that all descriptions of network devices in the above embodiments are applicable to the embodiments of this information transmission method and can achieve the same technical effect, so they will not be repeated here.

[0275] like Figure 8 As shown, this application embodiment provides a signal measurement device 800, applied to a terminal, including:

[0276] The first receiving unit 801 is used to receive a modulated signal sent by the forwarding node. The modulated signal is obtained by the forwarding node modulating the network device measurement signal. The modulated signal includes the network device measurement signal and the forwarding node measurement signal. The forwarding node measurement signal corresponds to the beam of the forwarding node.

[0277] The first acquisition unit 802 is used to acquire target measurement results based on the modulation signal, wherein the target measurement results include the beam quality corresponding to the beam of the forwarding node.

[0278] Optionally, the device further includes:

[0279] The third sending unit is used to send measurement reporting information to the network device according to the target measurement result. The measurement reporting information includes at least one of the following: beam quality corresponding to the beam of the forwarding node, and beam indication information corresponding to the beam of the forwarding node.

[0280] Optionally, the beam indication information includes at least one of the following:

[0281] Beam identification;

[0282] The measurement signal identifier of the relay node corresponding to the beam.

[0283] Optionally, the first receiving unit 801 is configured to:

[0284] Get configuration information;

[0286] The configuration information includes at least one of the following:

[0287] At least one measurement opportunity;

[0288] The beam identifier of the beam of the forwarding node;

[0289] The relay node's beam corresponds to the relay node's measurement signal identifier.

[0290] It should be noted that this device embodiment corresponds one-to-one with the above method embodiments. All implementation methods in the above method embodiments are applicable to this device embodiment and can achieve the same technical effect.

[0291] It should be noted that the division of units in the embodiments of this application is illustrative and only represents one logical functional division.
