[0058] The embodiments of the present application disclose a communication method, device and computer readable storage medium, which can reduce sensing interference and improve communication quality. The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0059] In order to better understand the embodiments of the present application, the related contents, terms or names related to the present application will be briefly introduced.

[0060] I. Sensing

[0061] The perception is mainly achieved by utilizing the transmission of electromagnetic waves, and can achieve the perception of the electromagnetic wave propagation environment, such as detecting, positioning, identifying, imaging, and the like of a target object in the electromagnetic wave propagation environment. For example, a perception signal transmitter can send electromagnetic waves, a reflection signal of the electromagnetic waves reflected by a target object can be received by a perception signal receiver, and then the reflection signal and related data (such as the reception time of the reflection signal) of the reflection signal can be extracted by a processing device, and data analysis and the like are performed to obtain a perception result, which can reflect the size profile and the like of the target object. The reflection signal can also be referred to as a return signal.

[0062] With the development of communication technology, the frequency band used by the base station is also higher and higher, such as the millimeter wave frequency band. The higher the frequency band, the higher the perception resolution (such as spatial resolution) and the stronger the anti-interference ability. Therefore, when the base station has the perception ability brought by the millimeter wave frequency band, the wireless communication system / network can distinguish the perception of a specific area, object or event, and solve the perception demand in many scenarios (such as automatic driving, unmanned aerial vehicle monitoring). Based on this, the perception ability will become an important ability and characteristic of the future communication network, and the integration or fusion of communication and perception (referred to as the integration of communication and perception) is also the development direction of the future communication network. In the embodiments of the present application, the communication and perception can also be referred to as the integration of communication and perception.

[0063] For example, the perception ability of the wireless communication network can be applied in automatic / assisted driving, vehicle networking, intelligent transportation, 3D map reconstruction, intelligent industry, unmanned aerial vehicle monitoring and management, intelligent interaction, environment monitoring, posture detection and identification, and the like. For example, a high-precision dynamic map can be generated based on perception to assist unmanned aerial vehicles / smart cars in automatic driving. For another example, an abnormal posture such as a person falling can be identified based on perception and an alarm can be given. For another example, weather monitoring, pollution monitoring, pest and disease monitoring, and the like can be performed based on perception.

[0064] Common performance indicators of perception include perception accuracy, perception resolution, false alarm probability, and the like. The perception accuracy can generally represent the deviation between the perception result and the actual result, and can include distance accuracy, speed accuracy, angle accuracy, and the like. The perception resolution is the ability to distinguish different perception targets, and can include distance resolution, speed resolution, angle resolution, and the like. Among them, the distance resolution is the ability to distinguish adjacent targets in distance, which is usually measured by the minimum distinguishable distance interval. The speed resolution is the ability to distinguish targets in radial velocity, which is usually measured by the minimum distinguishable speed. The angle resolution / angle measurement accuracy is the ability to distinguish adjacent targets in angle, which is usually measured by the minimum distinguishable angle. The false alarm probability generally refers to the probability of being detected in the case that the target does not exist.

[0065] II. Perception method

[0066] It should be understood that, for one access network device or terminal device, it can act as a sensing signal transmitter or a sensing signal receiver. Therefore, there are various combinations of the transmitter and the receiver of the sensing signal, and according to the combination of the transmitter and the receiver of the sensing signal, the sensing mode (sensing mode) can be divided into the following six kinds: access network device self-transmission and self-reception (access network device self-transmits sensing signal and self-receives reflected signal), terminal device self-transmission and self-reception (terminal device self-transmits sensing signal and self-receives reflected signal), access network device cooperation (one access network device transmits sensing signal and another access network device receives reflected signal), access network device transmission and terminal device reception (access network device transmits sensing signal and terminal device receives reflected signal), terminal device transmission and access network device reception (terminal device transmits sensing signal and access network device receives reflected signal), and terminal device cooperation (one terminal device transmits sensing signal and another terminal device receives reflected signal). The above six sensing modes are shown in Table 1 as follows:

[0067] Table 1 Sensing mode examples

[0068] It should be noted that the two sensing modes of access network device self-transmission and self-reception and terminal device self-transmission and self-reception can be referred to as single-station sensing, and the other four sensing modes can be referred to as double-station sensing. The single-station sensing is that the sensing signal transmitter and the sensing signal receiver are the same device, and the single-station sensing mode is also referred to as self-transmission and self-reception mode. For the double-station sensing, the sensing signal transmitter and the sensing signal receiver are different devices, and the double-station sensing mode is also referred to as A-transmission and B-reception mode.

[0069] In the embodiments of the present application, the sensing signal transmitter can also be referred to as a sensing signal sending node, and the sensing signal receiver can also be referred to as a sensing signal receiving node. Moreover, the sensing signal receiving node and the sensing signal sending node can be collectively referred to as a sensing node. In the case of access network device self-transmission and self-reception and terminal device self-transmission and self-reception, the sensing signal receiving node and the corresponding sensing signal sending node are the same node.

[0070] III. Precoding

[0071] In a multiple input multiple output (MIMO) system, in order to effectively ensure the transmission performance of uplink data and downlink data, the uplink transmission signal and the downlink transmission signal are usually pre-encoded.

[0072] For example, in a communication and sensing fusion scenario, a channel between a base station and a terminal can be measured, and then a suitable precoding matrix can be selected based on the channel measurement result to improve the communication performance of the terminal. For example, for uplink, a terminal device can send a sounding reference signal (SRS) to an access network device. The access network device can perform uplink channel measurement according to the SRS sent by the terminal device, and determine the precoding matrix, modulation and coding scheme (MCS) and other information of the uplink transmission. Then, the access network device can send a transmitted precoding matrix indicator (TPMI) index, MCS and the like to the terminal device. The TPMI index can be used to identify the precoding matrix used for uplink transmission. The terminal device can determine the precoding matrix based on the indicated TPMI index, precode the uplink data, and then send the uplink data.

[0073] In a communication and sensing fusion networking scenario, the access network devices and terminal devices in the communication network can perform sensing on objects without communication function while communicating. In this case, sensing can interfere with communication. For example, for a terminal device, sensing of a neighboring cell can interfere with communication of a serving cell, or sensing of a neighboring base station can interfere with communication of a serving base station. For example, in a communication and sensing fusion networking scenario, part of the access network devices can communicate while the other part of the access network devices can perform sensing. As shown in FIG. 1, the access network devices in the middle perform sensing, and the access network devices around the middle perform communication. In this case, the sensing of the access network devices in the middle can interfere with the communication of the access network devices around the middle.

[0074] Since the transmission of sensing signals is generally periodic, in the embodiments of the present application, to solve the above problems, the access network devices or terminal devices for communication can measure the sensing interference, and then suppress the sensing interference of the neighboring cell or the neighboring base station based on the measurement result to improve the communication performance.

[0075] To better understand the embodiments of the present application, the system architecture of the embodiments of the present application will be described first.

[0076] Please refer to FIG. 2, which is a system architecture diagram provided by an embodiment of the present application. As shown in FIG. 2, the system architecture can include a terminal device and an access network device. It should be understood that the terminal device can include one or more terminal devices (one is shown in FIG. 2), and the access network device can include one or more access network devices (one is shown in FIG. 2).

[0077] The access network devices can communicate with each other through a fiber interface or an Xn interface. The access network device and the terminal device can communicate with each other through an air interface (i.e., an air interface such as a Uu interface). The communication between the terminal device and the access network device can include uplink communication (i.e., communication from the terminal device to the access network device) and downlink communication (i.e., communication from the access network device to the terminal device). In the uplink communication, the terminal device can be configured to send an uplink signal to the access network device, and the access network device can be configured to receive the uplink signal from the terminal device. In the downlink communication, the access network device can be configured to send a downlink signal to the terminal device, and the terminal device can be configured to receive the downlink signal from the access network device. The uplink communication corresponds to an uplink, and the downlink communication corresponds to a downlink. The terminal device can also be configured to send a signal to another terminal device, or receive a signal from another terminal device, or receive a back echo signal of a signal sent by itself. The access network device can also receive a back echo signal of a signal sent by itself.

[0078] A terminal device, which can also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), a customer premise equipment (CPE), etc., is a device with wireless communication function, which can provide voice and / or data connectivity to users. A terminal device can be a handheld terminal, a notebook computer, an RSU (road side unit), a subscriber unit, a cellular phone, a smart phone, a wireless data card, a personal digital assistant (PDA) computer, a tablet computer, a tag, a wireless modem, other processing devices connected to a wireless modem, a handheld device, a laptop computer, a cordless phone, or a wireless local loop (WLL) station, a machine type communication (MTC) terminal, a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electricity meter, etc.), a smart robot, a plant device, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, or a wireless terminal in smart home, a flight device (such as a smart robot, a hot air balloon, a drone, an airplane, etc.) or other devices that can access a network. A terminal device can be fixed or mobile, and can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can also be deployed on water (such as a ship, etc.); and can also be deployed in the air (such as an airplane, a balloon and a satellite, etc.).

[0079] The access network device can be a device providing access / communication services for the terminal device, and can include a radio access network (RAN) device and an access node (AN) device. The RAN device can include various forms of base stations, such as macro base stations, micro base stations (also referred to as small stations), relay stations, access points, balloon stations, and the like. In systems employing different wireless access technologies, the names of the radio access network devices can differ. For example, evolved NodeB (eNB or eNodeB) in long term evolution (LTE), next generation NodeB (gNB) in the 5th generation (5G) mobile communication system, ng-eNB (4G base station accessing a 5G core network). The radio access network device can also be a radio controller in a cloud radio access network (CRAN) scenario, a base station device in a future network (such as 6G, 7G, etc.), a radio access network device in a future evolved public land mobile network (PLMN) network, a wearable device, a vehicle-mounted device, a transmission and reception point (TRP), a radio network controller (RNC), a home base station (for example, a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access node (AP) in a wireless fidelity (WiFi) system, and the like.

[0080] In some deployments, an access network device (e.g., gNB) can include one or more centralized units (CUs) and one or more distributed units (DUs), etc. The access network device can also include one or more radio units (RUs). The access network device can communicate with a core network via a backhaul, and with a terminal device (UE) via an air interface (e.g., Uu interface). Specifically, a baseband unit (BBU) in the access network device can communicate with the core network via the backhaul, and a radio unit in the access network device can communicate with the terminal device via the air interface. Also, the BBU can communicate with the RU via a front-haul, and the BBU and the RU can or can not be co-located. The BBU can include at least one central unit (CU) and at least one distributed unit (DU), and the CU and the DU can communicate via a mid-haul. The CU can implement part of the functions of the access network device, the DU can implement part of the functions of the access network device, and the CU can be used to control the operation of one or more DUs. For example, the CU can implement the functions of the radio resource control (RRC) and the packet data convergence protocol (PDCP) layer, and can also implement the function of the service data adaptation protocol (SDAP) layer, the DU can implement the functions of the radio link control (RLC) and the media access control (MAC) layer, and can also implement part of the physical (PHY) layer (e.g., the higher physical (Higher PHY) layer) or all of the physical layer functions, and the RU can be used to implement part of the physical layer functions (e.g., the lower physical (Lower PHY) layer) and radio frequency functions. For specific descriptions of the above-mentioned protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). It can be understood that, in some possible implementations, the access network device can be a CU node or a DU node or a device including a CU node and a DU node.

[0081] Please refer to FIG. 3, which is another system architecture diagram provided by the embodiments of the present application. As shown in FIG. 3, the RAN 100 can be an open RAN (O-RAN or ORAN) system. The RAN nodes 110 (such as the RAN nodes 110a and 110b) can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged or arranged in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0082] It should be understood that the architectures of FIG. 2 and FIG. 3 are only illustrative, and other devices / network elements can also be included in the architectures shown in FIG. 2 and FIG. 3, which are not limited by the embodiments of the present application.

Moreover, in order to facilitate the description, the description of “network element” is omitted in some of the following descriptions, for example, the NEF network element is simply referred to as NEF, in which case “NEF” should be understood as the NEF network element or the NEF entity, and similar understanding should be made for other network elements or functions. That is, the function, the functional network element, and the functional entity can be equivalent, such as the UDM, the UDM network element, and the UDM entity, which can be equivalent.

[0085] It should be understood that the technical solutions provided by the embodiments of the present application can be applied to communication systems of various radio access technologies (RATs), such as: a fifth generation (5th generation, 5G) communication system, a transition system between a 5G communication system and a 6G communication system (the transition system can also be referred to as a 5.5G communication system), a network of multiple system fusion, and the like; of course, it can also be a future communication system, such as a sixth generation (6th generation, 6G) or even a seventh generation (7th generation, 7G) communication system, and the like.

[0086] It should be noted that the system architecture, network architecture, and service scenario (or application scenario) described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0087] In order to better understand the embodiments of the present application, the overall concept of the embodiments of the present application will be described first.

[0088] As can be known from the above description, in the sensing fusion scenario, the sensing signal can cause interference to the communication signal and affect the communication performance. Among them, for the sensing signal, the transmission of the sensing signal generally has a certain periodicity, for example, within a sensing result refresh range, the corresponding access network device will periodically scan the sensing beam. Based on this, the related terminal device / access network device can measure the sensing interference, that is, measure the sensing signal transmitted in the sensing frame, and in the subsequent communication process, the measurement result can be used to suppress the sensing interference. For example, the related terminal device / access network device can select a suitable precoding matrix based on the measurement result, and the transmitter can use the precoding matrix for precoding in the subsequent communication process, thereby realizing the suppression of the sensing interference.

[0089] In the embodiments of the present application, in order to facilitate description, the following is described by taking an example that a second device transmits a communication signal to a first device, and a sensing signal interferes with the communication signal between the second device and the first device. Among them, there are many possible situations for the first device and the second device, for example, the second device can be a terminal device, and the first device can be an access network device, that is, the service access network device of the second device, at this time the sensing signal can cause interference to the uplink communication. For another example, the second device can be an access network device, that is, the service access network device of the second device, and the first device can be a terminal device, at this time the sensing signal can cause interference to the downlink communication. It should be understood that the two cases exemplified here are only exemplary descriptions and do not constitute a limitation.

[0090] The overall flow of the technical solutions provided by the embodiments of the present application will be exemplarily described below. Please refer to FIG. 4, which is a flow diagram of a communication method disclosed by the embodiments of the present application. As shown in FIG. 4, the method can include but is not limited to the following steps:

[0091] 401. The first device receives a first resource indication, the first resource indication being used to indicate a first sensing resource.

[0092] When the second device sends a communication signal to the first device, the related sensing signal will cause interference to the communication signal. In order to suppress the sensing interference, the related device can indicate the sensing resource corresponding to the sensing signal to the first device, so that the first device measures the sensing interference based on the sensing resource. Exemplarily, the first device can receive a first resource indication, the first resource indication can be used to indicate a first sensing resource, and the first sensing resource can be used to send the sensing signal. Specifically, the following illustrates the sending of the first resource indication in two different cases. In the case where the first device is a terminal device and the second device is an access network device, the first device can receive the first resource indication from the second device, or the first device can receive the first resource indication from a third device, which can be a neighboring access network device of the second device. In the case where the first device is an access network device and the second device is a terminal device, the first device can receive the first resource indication from a fourth device, which can be a neighboring access network device of the first device. That is, the access network device (such as the third device, the fourth device, etc.) configured with the sensing resource (such as the first sensing resource) can send the sensing resource configuration to the first device, or send it to the first device through the second device, so that the first device measures the sensing interference.

[0093] In some possible implementation manners, the first device can receive measurement configuration information, which can include the first resource indication to configure the related measurement resource. The first sensing resource can include a time domain resource, a frequency domain resource, and a sensing sequence.

[0094] It can be understood that the first sensing resource can be used to measure the sensing interference. For example, it can be used to measure the interference of the sensing signal to the uplink communication and / or the interference of the sensing signal to the downlink communication.

[0095] In some possible implementations, the first sensing resource can be a sensing resource corresponding to a neighbor cell device of the first device and / or a neighboring access network device of the second device. For example, in a case that the first device is a terminal device and the second device is an access network device, the first sensing resource can be a sensing resource corresponding to a neighbor cell device of the first device and / or a neighboring access network device of the second device, so as to measure interference caused by the sensing of the neighbor cell device and / or the neighboring access network device to downlink communication of the terminal device. For another example, in a case that the first device is an access network device and the second device is a terminal device, the first sensing resource can be a sensing resource corresponding to a neighbor cell device of the second device or a neighboring access network device of the first device, so as to measure interference caused by the sensing of the neighbor cell device and / or the neighboring access network device to uplink communication of the terminal device. It should be understood that the neighbor cell device can be understood as a device in a neighbor cell, such as a terminal device in a neighbor cell, and the neighbor cell can be understood as a nearby cell or a nearby non-serving cell. For example, the neighbor cell device of the first device can be understood as a device in another cell near the first device or a device in another non-serving cell near the first device. It should also be understood that the neighboring access network device can be understood as a nearby access network device. For example, the neighboring access network device of the second device can be understood as an access network device near the second device, such as an access network device adjacent to the second device. It should be understood that in some other possible implementations, the first sensing resource can be a sensing resource corresponding to a serving cell and / or a serving access network device.

[0096] It should be noted that the sensing signal can be periodically transmitted, that is, the sensing signal that causes interference to the communication signal transmitted by the second device to the first device can be periodically transmitted. Moreover, the frequency domain resource used by the sensing signal each time it is transmitted and the sensing sequence can be the same. Based on this, by measuring the interference of the first transmitted sensing signal, the interference caused by the sensing signal in the subsequent communication process can be suppressed. For example, assuming that the transmission resource of the sensing signal includes resource 1 (such as the last 1 OFDM symbol of time slot 1), resource 2 (such as the last 1 OFDM symbol of time slot 2), resource 3 (such as the last 1 OFDM symbol of time slot 3), and resource 4 (such as the last 1 OFDM symbol of time slot 4), in this case, the sensing interference can be measured by resource 1, and a suitable precoding matrix can be selected based on the measurement result. In subsequent communication, the second device can use the precoding matrix for precoding when transmitting the communication signal to the first device on resource 2, resource 3, and resource 4, so as to suppress the sensing interference. The frequency domain resource used by the second device to transmit the communication signal to the first device can be the same as the frequency domain resource of the sensing signal. It should be understood that there are various ways to periodically transmit the sensing signal, for example, the sensing signal can be periodically transmitted after being configured, or the sensing signal can be periodically transmitted within a certain time period, such as within a sensing result refresh range, and the embodiments of the present application do not limit this.

[0097] In some possible implementation manners, the sensing signal can also be non-periodically transmitted, but the frequency domain resource used by the sensing signal each time it is transmitted and the sensing sequence can be the same. In this case, the sensing interference in the subsequent communication process can also be suppressed by measuring the interference of the first transmitted sensing signal. It can be understood that the sensing signals transmitted by the same frequency domain resource and sensing sequence in the embodiments of the present application can be sensing signals for the same sensing task or the same sensing result. The frequency domain resource can be a subcarrier, a resource block (RB), etc., and the time domain resource can be a time slot, a sub-slot, a mini-slot, a symbol, etc., and the embodiments of the present application do not limit this.

[0098] It can be understood that in some possible implementation manners, the first sensing resource can be the sensing resource when the sensing signal is first transmitted.

[0099] 402. The first device measures the sensing signal corresponding to the first sensing resource to obtain a first measurement result, and the first measurement result is used to determine a target precoding matrix.

[0100] After the first device receives the first resource indication, the first device can measure a sensing signal corresponding to the first sensing resource of the first resource indication to obtain a first measurement result. The first measurement result can be used to determine a target precoding matrix, which can be used to precode a communication signal. It should be understood that the first measurement result can include an interference condition of the sensing signal corresponding to the first sensing resource. For example, the first measurement result can be an interference covariance matrix corresponding to the sensing signal or information used to obtain the interference covariance matrix corresponding to the sensing signal.

[0101] For example, a common way of quantizing and feeding back a spatial correlation matrix is introduced as follows. The way quantizes and feeds back a spatial correlation matrix with discrete fourier transform (DFT) vectors as basis vectors. Each basis vector can correspond to an angle. For example, the base station antenna array is a rectangular surface array, where the number of horizontal antennas is N1 and the number of vertical antennas is N2. The basis vector is where n1∈{0,1,2,…,N1O1-1},n2∈{0,1,2,…,N2O2-1} represents the index of the basis vector, O1,O2 represents the oversampling factor, represents the Kronecker product. The terminal device can quantize the spatial correlation matrix according to the basis vector, and select K basis vectors with the largest coefficients, and report the indices n 1,k 2,k ,k=0,1,2,…,K-1 and the corresponding coefficients p k to the base station. The base station can recover the spatial correlation matrix

[0102] For a spatial-frequency correlation matrix, for example, the base station antenna array is a rectangular surface array, where the number of horizontal antennas is N1, the number of vertical antennas is N2, and the number of frequency domain samples is N3. The spatial-frequency basis vector is where n1∈{0,1,2,…,N1O1-1},n2∈{0,1,2,…,N2O2-1},n3∈{0,1,2,…,N3-1} represents the index of the basis vector, O1,O2 represents the spatial oversampling factor, represents the Kronecker product. The terminal device can quantize the spatial-frequency correlation matrix according to the spatial-frequency basis vector, and select K spatial-frequency basis vectors with the largest coefficients, and report the indices n 1,k 2,k 3,k ,k=0,1,2,…,K-1 and the corresponding coefficients p k to the base station. The base station can recover the spatial correlation matrix ​​​

[0103] 403. The second device acquires the target precoding matrix.

[0104] In embodiments of the present application, the second device acquires the precoding matrix in multiple ways, three of which are exemplified below.

[0105] In the first way, after the first device measures the first measurement result, it can send the first measurement result to the second device. Correspondingly, the second device can receive the first measurement result from the first device, and then the second device can determine the target precoding matrix based on the first measurement result.

[0106] In the second way, after the first device measures the first measurement result, it can determine the target precoding matrix based on the first measurement result, and then send the target precoding matrix to the second device. Correspondingly, the second device can receive the target precoding matrix from the first device.

[0107] In the third way, after the first device measures the first measurement result, it can select a suitable precoding matrix from a preset codebook based on the first measurement result, and the precoding matrix is the target precoding matrix. Then, the first device can send first indication information to the second device, which can be used to indicate the target precoding matrix. The first indication information can be the number, index, or other information that can identify the target precoding matrix, which is not limited in embodiments of the present application. Exemplarily, the first device and the second device can both include a preset codebook, which can include multiple precoding matrices, each of which can include an index. After the first device selects a precoding matrix from the preset codebook, it can send the index of the precoding matrix to indicate that the second device uses the precoding matrix corresponding to the index.

[0108] It can be understood that the target precoding matrix can be an uplink precoding matrix or a downlink precoding matrix.

[0109] In some possible implementations, in addition to measuring the perceived interference, the first device can also measure the channel from the second device to the first device to obtain a channel measurement result from the second device to the first device, for example, in the case where the second device is an access network device and the first device is a terminal device, the first device can measure the channel state information reference signal (CSI-RS) to obtain a downlink channel measurement result. Then, the first device or the second device can determine the target precoding matrix based on the channel measurement result from the second device to the first device (such as the downlink channel measurement result) and the measurement result of the perceived interference (such as the first measurement result), so as to improve the communication quality from the second device to the first device.

[0110] The following illustrates a manner of determining a target precoding matrix.

[0111] Taking the UE sending SRS as an example, the communication base station can obtain the channel H between the communication UE and the communication base station by receiving the SRS signal, the dimension of which is Nr*Nt, and Nr and Nt are the number of antennas of the UE and the communication base station, respectively. Meanwhile, the UE feeds back the interference of the sensing base station measured by the UE to the communication base station, denoted as R. At this time, the precoding matrix of the UE can be obtained at the base station side by calculation according to the following formula: W = (I + H H R -1 H) -1 H H R -1

[0112] I is the unit matrix, and W is the precoding matrix.

[0113] 404. The second device precodes the communication signal based on the target precoding matrix.

[0114] In the subsequent communication process, when the second device sends the communication signal to the first device, the second device can precodes the communication signal based on the target precoding matrix. Specifically, since the target precoding matrix can be used to suppress the interference of the sensing signal, and the sensing signal can not be continuously sent, in the part of the time-frequency resources of the second device sending the communication signal to the first device which is the same as the time-frequency resources of the sensing signal, the second device can precodes the communication signal based on the target precoding matrix. As for other parts, the second device can not use the target precoding matrix, and can use the precoding matrix determined based on the SRS or CSI-RS measurement result. For example, assuming that the communication resources of the second device sending the communication signal to the first device include time-frequency resource 1, time-frequency resource 2, time-frequency resource 3, time-frequency resource 4, time-frequency resource 5, and time-frequency resource 6, and the time-frequency resources corresponding to the sensing signal include time-frequency resource 1, time-frequency resource 3, and time-frequency resource 5, in this case, the second device can use the target precoding matrix when sending the communication signal to the first device in time-frequency resource 1, time-frequency resource 3, and time-frequency resource 5, so as to suppress the sensing interference, and can not use the target precoding matrix when sending the communication signal to the first device in time-frequency resource 2, time-frequency resource 4, and time-frequency resource 6, since there is no sensing interference, the precoding matrix determined based on the SRS or CSI-RS measurement result can be used.

[0115] It can be understood that, in order to suppress the sensing interference by the target precoding matrix, the second device needs to know the resource of the sensing signal, i.e., in which resource the sensing signal is transmitted. Exemplarily, the second device can receive a second resource indication (such as a resource set), and the second resource indication can indicate a second sensing resource, which is the transmission resource of the sensing signal. Then, the second device can use the target precoding matrix based on the second sensing resource. In the case that the first device is a terminal device and the second device is an access network device, the first device can receive the second resource indication from the second device, or the first device can receive the second resource indication from a third device, which can be a neighboring access network device of the second device. In the case that the first device is an access network device and the second device is a terminal device, the first device can receive the second resource indication from a fourth device, which can be a neighboring access network device of the first device. That is, an access network device (such as the third device, the fourth device, etc.) that configures the sensing resource (such as the first sensing resource) can transmit the sensing resource configuration to the first device, or transmit the sensing resource configuration to the first device through the second device, so as to facilitate the first device to measure the sensing interference.

[0116] In some possible implementation manners, the first device and / or the second device can further receive second indication information, which is used to indicate a sensing mode, i.e., the sensing mode corresponding to the neighbor cell or the neighboring access network device. The sensing mode can include one or more of the following: access network device to terminal device, terminal device to access network device, access network device self-to-self, terminal device self-to-self, access network device A to access network device B, and terminal device A to terminal device B. Some sensing modes can only cause sensing interference to downlink communication, such as the access network device to terminal device and the access network device self-to-self, and some sensing modes can only cause sensing interference to uplink communication, such as the terminal device to access network device and the terminal device self-to-self. Therefore, the terminal device or the access network device can be controlled to measure based on the sensing mode. Exemplarily, assuming that the sensing mode is the access network device to terminal device, after the access network device receives the second indication information, it can be determined that the sensing interference is caused to the downlink communication, and the access network device can trigger the terminal device to measure the sensing interference, so that the sensing interference can be suppressed based on the measurement result in the subsequent, and the downlink communication quality can be improved. Exemplarily, assuming that the sensing mode is the terminal device to access network device, after the access network device receives the second indication information, it can be determined that the sensing interference is caused to the uplink communication, and the access network device itself can measure the sensing interference, so that the sensing interference can be suppressed based on the measurement result in the subsequent, and the uplink communication quality can be improved.

[0117] In the process, in the case that the sensing signal interferes with the communication signal sent by the second device to the first device, the first device can measure the interference of the sensing signal, and then determine (or select) a suitable precoding matrix based on the interference measurement result of the sensing signal. In the subsequent communication process, the second device can use the precoding matrix for precoding when sending the communication signal to the first device, so as to reduce the interference of the sensing signal and improve the communication performance. Moreover, since the frequency domain resource and the sensing sequence used by the sensing signal are the same each time the sensing signal is sent, the sensing interference is measured only once, and the measurement overhead is small.

[0118] It can be understood that the technical solutions provided by the embodiments of the present application can be used in the architecture of an open access network. The operations performed by the access network device can be performed by a CU, a DU, a CU-CP, a RIC (such as a near-RT RIC), and the like. The information sent by the terminal device to the access network device can be sent to a CU, a DU, a CU-CP, or a RIC (such as a near-RT RIC), and the like. The embodiments of the present application do not limit this. For example, the access network device can configure the sensing resource and the like that the terminal device needs to measure through a CU, a DU, or a CU-CP. The access network device can also configure the sensing resource and the like that the terminal device needs to measure through a RIC.

[0140] In a possible implementation, in the communication device shown in FIG. 5 and FIG. 6, the processing unit can be one or more processors / logic circuits, the sending unit can be a transmitter, and the receiving unit can be a receiver. The sending unit and the receiving unit can be integrated into one device, for example, a transceiver. In the embodiments of the present application, the processor and the transceiver can be coupled, and the connection manner of the processor and the transceiver is not limited in the embodiments of the present application. In the process of executing the above method, the process of sending information (for example, sending the first measurement result) in the above method can be understood as the process of outputting the above information by the processor. When the above information is output, the processor outputs the above information to the transceiver, so that the transceiver transmits. After the above information is output by the processor, it may also need to be processed further, and then reach the transceiver. Similarly, the process of receiving information (for example, receiving the first measurement result) in the above method can be understood as the process of receiving the input above information by the processor.

[0142] FIG. 7 shows a possible hardware structure of the communication apparatus 700 provided by the embodiment of the present application. The communication apparatus 700 can include a processor 701 and a transceiver 702. It should be noted that FIG. 7 only shows the main components of the communication apparatus 700, and the communication apparatus 700 can further include a memory 703, an input / output device (not shown in the figure), etc.

[0143] The processor 701 is mainly used for processing communication protocols and communication data, and controlling the whole communication apparatus, executing software programs, and processing data of the software programs. The memory 703 is mainly used for storing software programs and data. The transceiver 702 can include a control circuit and an antenna.

The input / output device, for example, a touch screen, a display screen, a keyboard, etc., is mainly used for receiving data input by a user and outputting data to the user.

[0144] When the communication apparatus is powered on, the processor 701 can read the software programs in the memory 703, interpret and execute the instructions of the software programs, and process the data of the software programs. When data needs to be transmitted wirelessly, the processor 701 can output the baseband signals of the data to be transmitted to the control circuit after baseband processing, the control circuit can convert the baseband signals into radio frequency signals, and transmit the radio frequency signals in the form of electromagnetic waves through the antenna. When data is transmitted to the communication apparatus, the control circuit receives the radio frequency signals through the antenna, converts the radio frequency signals into baseband signals, and outputs the baseband signals to the processor 701. The processor 701 converts the baseband signals into data and processes the data.

[0145] In a possible implementation, the control circuit and the antenna can be arranged independently of the processor for baseband processing, for example, in a distributed scenario, the control circuit and the antenna can be arranged remotely from the communication apparatus.

[0146] The processor 701, the transceiver 702, and the memory 703 can be connected through a communication bus.

For details, refer to the related description of FIG. 4, which will not be repeated here.

[0152] It should be noted that the communication apparatus 700 shown in FIG. 7 is only one implementation of the embodiments of the present application, and in actual applications, the communication apparatus 700 can also include more or fewer components, which is not limited here.

[0153] FIG. 8 shows a possible architecture of a RAN chip according to an embodiment of the present application. As shown in FIG. 8, the RAN chip can include a CU, a DU and a RU. The CU can perform the functions of upper layer L2 and L3. The DU can perform the functions of L1 and part of L2. The RU can perform the functions of L1 computation and RF digital part.

The fronthaul interface is used to carry the traffic between the RU and the DU. Exemplarily, the integrated DU can include the functions of the DU and the RU described above.

[0154] The CU / DU hardware can include a chassis platform, a motherboard, peripherals and cooling equipment. The motherboard can include a processing unit, a memory, an internal input / output (I / O) interface and an external connection port. The CU system can be implemented using a multi-core processor and one or more hardware accelerators.

[0155] The DU system can be implemented using a multi-core processor and one or more hardware accelerators. Part of the DU protocol stack can be implemented in software running on the multi-core processor. The computation-intensive L1 and L2 functions can be offloaded to hardware accelerators based on field programmable gate array (FPGA) / graphics processing unit (GPU). Alternatively, all L1 functions can be offloaded to hardware accelerators based on FPGA / GPU, while other protocol stack contents are implemented in software running on the processor. Alternatively, all protocol stacks are implemented in software running on the processor. The hardware accelerators support interconnection with x86 or non-x86 processors (such as ARM processors). Similarly, the accelerators have a multi-lane peripheral component interconnect express (PCIe) interface pointing to the CPU, and are externally connected through a gigabit ethernet (GbE) connection. It should be understood that the hardware accelerators can be designed with interfaces, and the hardware function components can include storage of software, hardware and system debugging interfaces, and a single board management controller.

[0156] The RU can include three parts, namely, an O-RAN processing unit (OPU), a digital processing unit (DPU), and an RF processing unit. The OPU can receive eCPRI frames from the O-RAN fronthaul and perform fronthaul interface, bottommost L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping, etc. The OPU can be implemented as a CPU, FPGA, or ASIC. The DPU can perform synchronization, DDC (digital down conversion in UL), DUC (digital up conversion in DL), CFR, and DPD to improve power amplifier efficiency by reducing PAPR / ACLR of the RF front end. The DPU can be implemented as a FPGA or ASIC. The RF processing unit can include a transceiver module, up / down converter, power amplifier (PA), low noise amplifier (LNA), Tx / Rx filter. All conversions between analog and digital domains (DAC and ADC) (e.g., RF sampling, frequency conversion using RF, IF, and LO mixing in upconversion and downconversion) can be performed within the transceiver module.

[0157] FIG. 9 shows a possible hardware structure of a baseband chip according to an embodiment of the present application. As shown in FIG. 9, the baseband chip can be implemented by a processing system including one or more processors.

[0158] For example, the processor can be a microprocessor (e.g., X86, ARM), a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), a GPU, a programmable logic device (PLD), a state machine, gated logic, discrete hardware circuits, and other suitable hardware configured to perform various functions.

[0159] The processing system can be implemented with a bus architecture, generally represented by the bus. The bus can include any number of interconnecting buses and bridges, depending on the specific application of the processing system and the overall design constraints. The bus communicatively couples various circuitry including one or more processors (generally represented by the processor), memory (e.g., a memory), and computer-readable storage media (generally represented by the computer-readable media). The bus can also connect various other circuitry, such as a timing source, peripherals, voltage regulators, and power management circuitry, which are well known in the art, and therefore, will not be further described. A bus interface provides an interface between the bus and a transceiver and between the bus and an interface.

[0160] The transceiver provides a communication interface or means for communicating with various other apparatuses over a wireless transmission medium. The transceiver can be coupled to an antenna array, and the transceiver and antenna array can together function to communicate with a corresponding network type. At least one interface (e.g., network interface and / or user interface) provides a communication interface or means for communication over an internal bus or via an external transmission medium. The transceiver module is capable of implementing transmit functionality and receive functionality, and when the transceiver module implements transmit functionality, it can be referred to as a transmit module (sometimes referred to as a transmit unit), and when the transceiver module implements receive functionality, it can be referred to as a receive module (sometimes referred to as a receive unit). The transmit module and receive module can be the same functional module, which is referred to as a transceiver module, capable of implementing transmit functionality and receive functionality; or the transmit module and receive module can be different functional modules, and the transceiver module is a generic term to refer to these functional modules.
