Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal measurement and transmission method, device, terminal, network equipment and forwarding node. Background Art

[0002] The high frequency band has a short wavelength, poor reflection and diffraction performance, and large path loss, so multi-beams are usually used for communication coverage. In order to ensure the quality of user communication, it is necessary to measure and report the quality of the transmit and receive beams, and switch the optimal transmit and receive beam pair in time according to channel changes. However, in a wireless communication system that forwards base station signals through forwarding nodes (for example, Reconfigurable Intelligent Surface (RIS)), an additional hop is added between the base station and the user equipment (User Equipment, UE, also known as the terminal), and the link quality of the forwarding node will also affect the terminal communication.

[0114] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0118] The embodiments of the present application are described below in conjunction with the accompanying drawings. The signal measurement, transmission method, device, terminal, network device and forwarding node provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0119] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1As shown, it includes a user terminal 11, a base station 12 and a RIS13, and the base station 12 sends a signal to the user terminal 11 through the RIS13. Among them, the user terminal 11 can be a user equipment (User Equipment, UE), for example: it can be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 can be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or it is called a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

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

[0121] like Figure 1 In the RIS-based wireless communication link shown, it is assumed that the base station has M beams, the RIS has L beams (assuming that the number of RIS transmit and receive beams is the same), 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 is usually large in the mmWave band, an efficient beam measurement and reporting procedure is very important to achieve adequate coverage while ensuring low overhead and UE complexity.

[0122] In existing single-hop systems, for each TX beam, the measured quality of a beam pair (e.g., the best RX beam for a given TX beam) needs to be reported. The best RX beam is obtained at the UE through beam measurement and stored in the UE memory, but does not need to be reported. During 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 the 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 the associated beam quality) as a recommendation to the base station for downlink (DL) beamforming. If K>1, the UE can report the indicators of the K selected TX beams (e.g., the best K beams) and their measured quality (either relative or absolute) to the base station. The network then decides how to use the reported K beams for DL ​​transmission. For example, if the base station has only one Tx panel, it can compare the quality of the reported Tx beams and select one Tx beam for DL ​​transmission. If the base station has multiple Tx panels, different beams can be used on different panels for transmission.

[0123] The metric for beam measurement can be Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Channel State Information (CSI), among others. Different metrics lead to different UE complexities and may be suitable for different scenarios. For example, RSRP measurement is relatively simple and energy-efficient. It helps to quickly measure a large number of beams, which is useful for initial beam acquisition. CSI measurement is more complex, but provides more accurate beam information and can be used for beam refinement in a small group of candidate beams. CSI-based beam reporting is also faster because it combines 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, beam reporting based on RSRP or RSRQ requires a two-step procedure (e.g., beam training, and CSI reporting based on the Reference Signal (RS) configuration of the beam training results), which prolongs the scheduling delay.

[0124] The above beam measurement process is only for the single-hop link from the base station to the UE. The objects of measurement and reporting are mainly the transceiver beams on the base station side, and the transceiver beams on the UE side are only measured but not reported. For the two-hop link based on the RIS wireless communication link, take the following line as an example. If the UE directly measures the signal from the base station, it can only directly measure the information of the overall equivalent channel of the base station-RIS-UE, and obtain the beam measurement result of the transmit beam used by the base station, but cannot perform the measurement on the beam of the RIS-UE segment. Due to the movement of the UE, the channel from the RIS to the UE segment is constantly changing, and the measurement and reporting of the RIS transceiver beams also need to be considered. Since the transceiver beams of the RIS are controlled by a set of RIS phase shift matrices, that is, one RIS phase shift matrix corresponds to one RIS transceiver beam pair, after the RIS phase shift matrix is ​​determined, the RIS receive beam direction and the transmit beam direction 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, an embodiment of the present application provides a signal measurement, transmission method, apparatus, terminal, network equipment and forwarding node to achieve measurement of the beam of the forwarding node.

[0126] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0127] like Figure 2 As shown, an embodiment of the present application provides a measurement reporting method, which is executed by a terminal and includes:

[0128] Step S201, receiving a modulated signal sent by a forwarding node;

[0129] The modulated signal is obtained by the forwarding node modulating the network device measurement signal, and 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;

[0130] It should be noted that the forwarding node modulates the network device measurement signal and adds the forwarding node measurement signal, so that the terminal can measure the beam of the forwarding node based on the forwarding node measurement signal.

[0131] Step S202: acquiring a target measurement result according to the modulated signal, wherein the target measurement result includes: a beam quality corresponding to a beam of a forwarding node;

[0132] It should be noted that, in the embodiment of the present application, 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 to say, the communication architecture of the embodiment of the present application 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 the embodiment of the present application can be a RIS, a network-controlled repeater (NCR), a relay device, or other device that can realize signal forwarding.

[0133] Optionally, the network device measurement signal in an embodiment of the present application may be a reference signal, such as a channel state information reference signal (CSI-RS); it may also be a pilot signal, such as a demodulation reference signal (DMRS); the forwarding node measurement signal may be a reference signal, a rank indication (RI) or it may also be a predefined sequence (such as a ZC sequence, a Gold sequence, etc.).

[0134] It should be noted that, when the forwarding node measurement signal is a predefined sequence (also referred to as a measurement sequence), each sequence corresponds to a beam of a forwarding node, and each beam of all forwarding node arrays 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 constitute a sequence set, which is known by the network device, the forwarding node, and the terminal side. It should also be noted that each beam of each forwarding node is uniquely identifiable, and the forwarding node arrays in adjacent cells or service areas use different sequence sets to ensure that the beams of the forwarding nodes of the adjacent cells or control nodes can be uniquely identified.

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

[0136] It should be noted that in the embodiment of the present application, the network device measurement signal is modulated by the forwarding node to achieve the addition of the forwarding node measurement signal to the modulated signal sent by the forwarding node to the terminal, so that the terminal can 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, and the modulated signal includes the network device measurement signal and the forwarding node measurement signal. Optionally, the forwarding node modulates 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 first demodulate the modulated signal to obtain the forwarding node measurement signal. Optionally, the terminal can demodulate the forwarding node measurement signal through a filter, coherent or incoherent demodulation, etc.; after obtaining the forwarding node measurement signal, the forwarding node measurement signal can be measured to obtain the beam quality corresponding to the beam of the forwarding node.

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

[0140] Optionally, in one implementation, the forwarding node modulates the network device measurement signal to obtain the modulated signal, and the specific implementation includes:

[0141] The control matrix is ​​switched at a preset time point, and the received network device measurement signal is modulated 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 achieve the modulation of the forwarding node measurement signal into the network device measurement signal to obtain the modulated signal.

[0143] Optionally, in one implementation, switching the control matrix at a preset time point to modulate the received network device measurement signal to obtain a modulated signal includes:

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

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

[0146] Step S12: switching the control matrix at a preset time point according to the control configuration information, and modulating the received network device measurement signal to obtain a modulated signal;

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

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

[0149] It should be noted that the reflection coefficient matrix in the embodiment of the present application is used to represent the beam of the forwarding node. A reflection coefficient matrix represents a beam of a forwarding node, corresponding to an incident signal and a reflected signal direction of a forwarding node array. The reflection coefficient matrix can be determined by the network device according to prior information such as network deployment, channel information and / or beam information reported by the terminal. The forwarding node measurement signal corresponds to the beam of the forwarding node, that is, a forwarding node measurement signal represents the measurement information of a beam of the forwarding node, and usually the forwarding node measurement signal corresponds to the beam index of the forwarding node.

[0150] For example, taking the forwarding node as RIS and the beam of the forwarding node as RIS beam as an example, a possible control matrix generation (modulation by phase modulation) process 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 respectively (i.e., the added modulation information is used to represent the RIS measurement signal). Then the generation process of the control matrix corresponding to the RIS is as follows: Figure 3 shown.

[0152] It should be noted that after the terminal performs measurement to obtain the beam quality, it can also report beam-related information so that the network device can obtain the beam situation of the forwarding node and select a better beam for signal forwarding. Optionally, in one implementation, after obtaining the target measurement result according to the modulated signal, the method further includes:

[0153] According to the target measurement result, measurement reporting information is sent to the network device, where 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 reporting information sent by the terminal to the network device only includes relevant information of the beam of the forwarding node, that is, the beam quality corresponding to the beam of the forwarding node and / or the beam indication information corresponding to the beam of the forwarding node; if the terminal also measures the network device measurement signal, the terminal also needs to send relevant information of the beam of the network device to the network device, for example, the relevant information of the beam of the network device includes the beam quality corresponding to the beam of the network device and / or the beam indication information corresponding to the beam of the network device.

[0155] Optionally, since the forwarding node can use one beam or multiple beams to send a modulated signal, when only one beam is used for transmission, the terminal obtains the beam quality of this beam, and the terminal can only report the beam quality when reporting; if multiple beams are used for transmission, the terminal obtains the beam qualities of multiple beams. At this time, the terminal can select an optimal beam for reporting. Optionally, the terminal can report the beam quality and beam indication information of the optimal beam, or the terminal can only report the beam indication information of the optimal beam; or, when the terminal obtains multiple beam qualities, the terminal can select the optimal multiple beams for reporting. 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, when 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 only uses one beam to send the modulated signal. Because 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, when the measurement 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 send modulated signals. The terminal can determine the beam qualities of multiple beams respectively through measurement, and the terminal can select a beam with the best beam quality to report. After the terminal reports the beam indication information of the best beam through measurement reporting information, the network device can know which beam has the best beam quality.

[0158] For example, in the case where the measurement reporting information includes the beam quality corresponding to the beam of the forwarding node and the beam indication information corresponding to the beam of the forwarding node, in one case, it can be understood that the forwarding node uses one beam to send a modulated signal. In order to clarify the correspondence between the beam and the beam quality, the terminal needs to report the beam quality and the beam indication information at the same time; in another case, it can also be understood that the forwarding node usually uses multiple beams to send modulated signals. The terminal can determine the beam qualities of multiple beams respectively through measurement, and the terminal can select a beam with the best beam quality for reporting. The terminal can report the beam quality and the beam indication information corresponding to the beam of the forwarding node at the same time, and the network device After receiving the information sent by the terminal, the device can know which is the optimal beam and the beam quality corresponding to the optimal beam; in another case, it can also be understood that the forwarding node usually uses multiple beams to send modulated signals. The terminal can determine the beam qualities of multiple beams respectively through measurement, and the terminal can select multiple beams with better beam quality for reporting. At this time, the terminal needs to report the beam quality and beam indication information of the better beam at the same time. After receiving the information sent by the terminal, the network device can know which better beams are and the beam qualities corresponding to these beams. The network device can select an 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 identification;

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

[0162] A12, the forwarding node measurement signal identifier corresponding to the beam;

[0163] It should be noted that since each beam corresponds to a different forwarding node measurement signal, the forwarding node measurement signal can be used to indicate the beam. Optionally, the forwarding node measurement signal identifier can be a measurement signal index, an identifier of a 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. Through the indication of the beam identifier, the network device can clearly know which beam the terminal is measuring. This situation is suitable for the scenario where the beam identifier is 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 to the beam, after the network device obtains the forwarding node measurement signal identifier, it can determine which beam is corresponding based on the forwarding node measurement signal identifier. This situation is applicable to the situation where the beam identifier is not explicitly configured for the terminal. The terminal can determine the specific forwarding node measurement signal to be measured by demodulating the modulated signal.

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

[0167] It should be particularly noted here that: since the measurement signal is usually composed of a sequence, different measurement signals correspond to different sequences, so the measurement signal can be indicated by the sequence.

[0168] Optionally, in an implementation manner, the receiving of a modulated signal sent by a forwarding node includes:

[0169] Step S21, obtaining configuration information;

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

[0171] B11, at least one measurement opportunity;

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

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

[0174] It should be noted that the configuration information must usually include a measurement opportunity, which is used to indicate the time unit position for sending the measurement signal. By informing the terminal of the beam-related information of the forwarding node, the terminal can know which beams are used to send signals.

[0175] Optionally, B12 and B13 are optional. When there are at least two measurement opportunities (or time units), the terminal can determine which specific beams have sent 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 measurement signal will be sent in multiple time units (for example, in multiple channel state information (Channel State Information, CSI) resource settings or multiple CSI resource sets configured with the same channel state information reference signal (Channel State InformationReference Signal, CSI-RS) resources), and the forwarding node is configured to add the same forwarding node measurement signal in multiple time units; the terminal receives signals in multiple time units according to predefined rules or instructions of the network device, and performs joint detection based on the signals of multiple time units to obtain beam quality.

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

[0177] Optionally, the configuration information may be sent by the network device to the terminal, or may be agreed upon by the protocol; and the different contents contained in the configuration information may be obtained in different ways, for example, B11 is obtained by way of agreement, while B12 and / or B13 are obtained by way of network device configuration. Optionally, when the configuration information is configured by the network device, the network device may send the configuration information via DCI.

[0178] For example, when the configuration information includes a measurement time and a beam identifier of the beam of the forwarding node, the terminal receives the modulated signal at the measurement time indicated by the configuration information, and then measures the forwarding node measurement signal obtained by demodulation, so as to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information. By configuring the measurement time and the beam identifier, the terminal can clearly know which beams are to be measured.

[0179] For example, when the configuration information includes a measurement time, a beam identifier of the beam of the forwarding node, and a forwarding node measurement signal identifier corresponding to the beam of the forwarding node, the terminal receives the modulated signal at the measurement time indicated by the configuration information, and then measures the forwarding node measurement signal obtained by demodulation, so as to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information. Through the configuration of the measurement time, the beam identifier and the forwarding node measurement signal identifier, the terminal can clearly know which beams are to be measured, and clearly 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 a joint measurement of the forwarding node measurement signal obtained by demodulation in multiple measurement opportunities, so as to obtain the beam quality corresponding to the specific beam of the forwarding node. In this way, there is no need to configure the beam and the forwarding node measurement signal, 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 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 signal obtained by demodulation in multiple measurement opportunities, so as 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 based on the joint measurement, which can reduce the measurement overhead of the terminal and improve the speed of obtaining beam quality.

[0182] For example, when the configuration information includes multiple measurement opportunities and a 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 a joint measurement of the forwarding node measurement signals obtained by demodulation in multiple measurement opportunities, so as to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information, and the forwarding node measurement signal identifier and the beam are one-to-one corresponding. 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 speed of obtaining the beam quality.

[0183] For example, when the configuration information includes multiple measurement opportunities, the beam identifier of the beam of the forwarding node, 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, so as to obtain the beam quality corresponding to the beam of the forwarding node indicated by the configuration information. In this way, there is no need for the terminal to determine which beams are being measured based on the joint measurement, and the forwarding node measurement signal identifier and the beam are one-to-one corresponding. The terminal can directly determine the forwarding node measurement signal used to measure the measured beam according to the indication of the configuration information. This method can reduce the measurement overhead of the terminal and improve the speed of obtaining beam quality.

[0184] Step S22: receiving a modulated signal sent by the forwarding node through at least one beam during a measurement opportunity indicated by the configuration information;

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

[0186] In summary, an embodiment of the present application proposes a beam measurement and reporting method for a forwarding node. When the forwarding node reflects a network device measurement signal transmitted by the network device, the network device measurement signal is modulated by the forwarding node (for example, adding a fixed phase, or overall amplitude modulation, etc.), and then the modulation information added by the modulation (that is, the forwarding node measurement signal) is used to measure the beam of the forwarding node to obtain a measurement result, thereby enabling the terminal to measure the beam of the forwarding node, facilitating the network device to control the beam of the forwarding node, and improving the communication reliability of the terminal.

[0187] Taking the communication between the base station and the terminal through RIS as an example, the specific application of the embodiment of the present application is described as follows.

[0188] First of all, it should be noted that the signal received by the terminal side may be in the following three situations:

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

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

[0191] B. The terminal detects an unknown signal (signal from other signal sources in the environment) plus additional information (RIS beam indication) after RIS modulation. This situation can be understood as the terminal only detecting the RIS measurement signal.

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

[0193] C. The terminal detects the measurement signal sent by the base station, but fails to detect the additional RIS measurement signal after RIS modulation, that is, the terminal fails to detect the RIS measurement signal.

[0194] This situation means that the terminal can directly receive the signal from the base station without RIS forwarding.

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

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

[0197] Application 1: Measurement reporting based on one time unit

[0198] The terminal performs measurement reporting at the measurement timing indicated by the base station according to the configuration information configured by the base station (the configuration information includes the base station beam index, the RIS beam index and the measurement timing (also referred to as the receiving timing)). The specific process is as follows:

[0199] Step 11: The terminal receives configuration information (eg, 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 modulated signal at the measurement timing according to the configuration information, detects the base station measurement signal and the RIS measurement signal respectively according to the beam index indicated by the base station, and obtains the corresponding beam quality (eg, RSRP of the beam).

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

[0202] A possible beam measurement reporting process is shown as follows: Figure 4 As shown, the base station and the terminal perform transmission and reception of downlink control information in time unit 1, and the base station, RIS and the terminal perform signal transmission and detection 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 the same reporting criteria. For example:

[0204] Single beam measurement only reports beam quality;

[0205] The multi-beam measurement reports one or more beam identifiers that meet predefined rules, for example, the beam with the largest RSRP;

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

[0207] The RIS side mainly implements:

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

[0209] The main implementation of the base station:

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

[0211] The base station determines the control matrix according to 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 a reflection coefficient matrix and a RIS measurement signal to the terminal.

[0212] Application 2: Measurement reporting based on multiple time units

[0213] The base station transmits the same base station measurement signal in M ​​consecutive time units starting from the nth transmission time unit (e.g., n orthogonal frequency division multiplex (OFDM) symbols) after the control configuration information is sent;

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

[0215] According to the configuration information sent by the base station, the terminal receives the modulated signal at multiple predefined measurement opportunities for joint measurement and reporting. The specific process is as follows:

[0216] Step 21: The terminal receives configuration information (eg, DCI) sent by the base station and obtains a measurement opportunity.

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

[0218] Step 23: The terminal reports beam information (beam quality information and / or beam identification) 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 After receiving all M=3 groups of modulation signals, the terminal performs joint detection on the base station measurement signals and RIS measurement signals in all 3 groups of modulation signals, and determines 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 from the base station

[0221] The terminal performs measurement reporting at the measurement timing indicated by the base station according to the configuration information sent by the base station. The specific process is as follows:

[0222] Step 31: The terminal receives configuration information (eg, 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) at the measurement opportunity, performs measurement signal detection according to the beam index indicated by the base station, and only obtains the base station beam index and the corresponding beam quality.

[0224] Step 33: The terminal determines that the received signal is a direct signal sent 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 performs measurement reporting at the measurement timing indicated by the base station according to the configuration information sent by the base station. The specific process is as follows:

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

[0228] Step 42: The terminal receives a modulated signal (which has a one-to-one correspondence with a beam index) at a measurement opportunity, 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 5.

[0231] The terminal receives the signal at the measurement opportunity according to the configuration of the base station, and detects a modulated signal including the RIS measurement signal and a signal including only the base station measurement signal without the RIS measurement signal. The terminal can select the beam information (including beam index and / or beam quality) of a stronger link for reporting according to the beam qualities measured respectively, or report the information of both links, and the base station decides which link to select for signal transmission.

[0232] In summary, the embodiment of the present application solves the problem that in a wireless communication system based on RIS, it is difficult to measure and report the RIS beam because the RIS does not have signal processing capabilities. The beam measurement and reporting method proposed in the embodiment of the present application can solve the measurement and reporting problem of the RIS beam with low overhead and complexity.

[0233] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0234] The terminal involved in the embodiment of the present application, also known as the terminal device, may be a device that provides voice and / or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

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

[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 multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.

[0237] like Figure 6 As shown, an embodiment of the present application provides an information transmission method, which is applied to a forwarding node, including:

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

[0239] Optionally, the forwarding node in the embodiment of the present application may be a device such as RIS, NCR, etc. that can implement signal forwarding.

[0240] The network device measurement signal in the embodiment of the present application may be a reference signal, for example, a channel state information reference signal (CSI-RS); it may also be a pilot signal, for example, a demodulation reference signal (DMRS); the forwarding node measurement signal may be a reference signal, a rank indication (RI) or may also be a predefined sequence (for example, a ZC sequence).

[0241] Step S602, sending the modulated signal to the terminal;

[0242] It should be noted that in the embodiment of the present application, the network device measurement signal is modulated by the forwarding node to achieve the addition of the forwarding node measurement signal to the modulated signal sent by the forwarding node to the terminal, so that the terminal can measure the beam of the forwarding node.

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

[0244] The control matrix is ​​switched at a preset time point, and the received network device measurement signal is modulated 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 achieve the modulation of the forwarding node measurement signal into the network device measurement signal to obtain the modulated signal.

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

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

[0248] Optionally, usually, the control configuration information is transmitted from the network device to the forwarding node. For example, the network device may send the control configuration information to the forwarding node via an air interface, or the network device may 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, and the received network device measurement signal is modulated to obtain a modulated signal;

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

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

[0252] It should be noted that the reflection coefficient matrix in the embodiment of the present application is used to represent the beam of the forwarding node. A reflection coefficient matrix represents a beam of a forwarding node, corresponding to an incident signal and a reflected signal direction of a forwarding node array. The reflection coefficient matrix can be determined by the network device according to 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, a forwarding node measurement signal represents the measurement information of a beam of the forwarding node, and usually the forwarding node measurement signal corresponds to the beam index.

[0253] It should be noted that by regulating the sending of configuration information, the forwarding node can perform modulation accurately, thereby improving the accuracy of modulation.

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

[0255] like Figure 7 As shown, an embodiment of the present application provides an information transmission method, which is applied to a network device, including:

[0256] Step S701, sending a network device measurement signal to a forwarding node;

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

[0258] Step S702: receiving measurement reporting information sent by the terminal, where 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 a target measurement result, the target measurement result is obtained by the terminal according to a modulated signal sent by the forwarding node, and the target measurement result includes: a beam quality corresponding to a beam of the forwarding node;

[0260] 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 a forwarding node measurement signal. 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, where the configuration information includes at least one of the following:

[0263] at least one measurement opportunity;

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

[0265] The forwarding node measurement signal identifier corresponding to the beam of the forwarding node.

[0266] By sending the configuration information to the terminal through the network device, the configuration information can be adjusted in real time, and the configuration flexibility can be achieved.

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

[0268] Sending control configuration information to the forwarding node, where the control configuration information includes a control matrix, or the control configuration information includes a reflection coefficient matrix and the forwarding node measurement signal;

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

[0270] It should be noted that by regulating the sending of configuration information, the forwarding node can accurately perform modulation, thereby ensuring the accuracy of the modulated signal.

[0271] Optionally, in an implementation manner, in the method, 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 forwarding node measurement signal identifier corresponding to the beam; it should be noted that since each beam corresponds to a different forwarding node measurement signal, the forwarding node measurement signal can be used to indicate the beam. Optionally, the forwarding node measurement signal identifier can be a measurement signal index, an identifier of a sequence corresponding to the measurement signal, or a sequence corresponding to the measurement signal.

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

[0275] like Figure 8 As shown, the embodiment of the present application provides a signal measurement device 800, which is applied to a terminal, including:
