[0001] The present application claims priority to the Chinese Patent Application No. 202411093828.6, filed on August 8, 2024, and entitled "A communication method and a communication device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication technology, and in particular to a communication method and a communication device. BACKGROUND

[0003] With the development of communication technology, the perception task and the communication task of the terminal device are coordinated with each other to improve the communication experience of the terminal device.

[0004] In the case that the frequency domain resource and the time domain resource of the perception task and the communication task are configured to overlap, the perception task and the communication task will interfere with each other at the terminal device side, thereby causing the quality of the perception task and the communication task to decrease. SUMMARY

[0005] The present application provides a communication method and a communication device, which can reasonably adjust the resource configuration of the communication task or the perception task according to the time domain and / or beam characteristics of the communication perception interference, thereby avoiding the link cross interference of the perception task and the communication task.

[0006] To achieve the above technical purpose, the present application adopts the following technical scheme:

[0007] In a first aspect, a communication method is provided. The method is applied to a first network device. The first network device performs a first task with a first terminal device. The first task includes a communication task and / or a perception task. The first terminal device also receives a first signal sent by a second device. The first signal corresponds to a first perception task. The method includes: sending a first message. The first message includes a perception measurement parameter. The perception measurement parameter is determined according to configured resources of the first task and / or the first perception task. Sending a perception measurement signal. The perception measurement signal is used for the first terminal device to perform measurement according to the perception measurement parameter. Receiving a second message. The second message includes a first measurement report. The first measurement report is generated by the first terminal device in the case that a result of the measurement satisfies a condition corresponding to at least one threshold indicated by the perception measurement parameter. According to the second message, adjusting resources for performing the first task with the first terminal device, or instructing the second device to adjust resources of a perception task corresponding to the first signal.

[0008] In the implementation of the scheme, the first network device can determine the resource with interference according to the measurement report obtained by the first terminal device measurement. For example, the beam resource, frequency domain resource, time domain resource, etc. with interference is determined. It can be understood that the resource with interference can be included in the communication resource of the configured communication task, or the sensing resource of the configured sensing task. In this way, the first network device can adjust the resource of the communication task or the sensing task based on the known resource with interference, so that the communication task or the sensing task can avoid using the interference resource. It can be understood that as long as one of the communication task or the sensing task no longer uses the interference resource, the interference between the two tasks on the resource can be avoided.

[0009] In the example, the first task can also be a sensing task. In this example, the first network device can adjust the resource of the sensing task performed by the first network device or the sensing task performed by the second device through the first message of the resource with interference reported by the first terminal device, thereby avoiding the mutual interference of the two tasks on the interference resource.

[0010] In this way, whether the first task is a communication task or a sensing task, the above-mentioned scheme implementation can be used to avoid the interference of the first signal to the first task and improve the signal quality of the first task.

[0011] Based on the scheme implementation of the first aspect, since the sensing measurement parameter is determined according to the configured resource of the first task and / or the first sensing task, the resource of the sensing measurement indicated by the first network device to the first terminal device can be included in the configured communication resource and / or sensing task. In this way, the first terminal device can more specifically perform sensing measurement. For example, the first terminal device can perform sensing measurement on each resource in the configured communication resource, so as to determine whether there is an interference resource in the configured communication resource.

[0074] Hereinafter, the terms "first" and "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0075] With the development of wireless communication technology, the 6th Generation Mobile Communication Technology (6G) has begun to be widely concerned.

[0076] Compared with the 5th Generation Mobile Communication Technology (5G), 6G focuses on communication services and basic positioning services.

[0077] 6G will integrate sensing and communication capabilities to build an Integrated Sensing and Communication (ISAC) system to model the spatial structure, mobility, and surrounding environment of unconnected devices and connected devices. Typical sensing scenarios can include ranging and speed measurement, high-precision positioning and tracking, imaging, target detection, pattern recognition, etc. Among them, the sensing objects of the sensing scenario can include users, etc.

[0078] In the ISAC system, the sensing function and the communication function empower each other. On the one hand, the communication system assists the sensing function, such as extracting sensing information from the communication signal while sensing, enhancing the sensing function. On the other hand, the sensing system assists the communication function, such as using the results of the sensing scan to assist beam management.

[0079] In actual system deployment, the sensing system and the communication system can be integrated in stages. The first stage is business coexistence, that is, the communication system and the sensing system use independent hardware and regard each other as interference. The second stage is capability mutual assistance, that is, the communication system and the sensing system use independent hardware but share information. The third stage is the integration of communication and sensing (referred to as the integration of sensing and communication), that is, the communication and sensing systems are integrated into one system, sharing hardware, resources, an integrated air interface, and an integrated waveform.

[0080] Taking the first stage and the second stage deployment as examples, the communication system and the sensing system are respectively configured with corresponding base stations (BSs). For example, the base station used for performing the communication task can include BS1, and the base station used for performing the sensing task can include BS2. BS1 and BS2 are different.

[0081] Correspondingly, in the case of third stage deployment, BS1 can implement partial or full hardware sharing with BS2, for example, BS1 and BS2 can be the same base station.

[0082] Taking the communication task scenario as an example.

[0083] In this example, BS1 can perform the transmission of data or commands of the communication task with the user equipment (UE) based on the communication link, thereby realizing the communication task. It can be understood that in some implementations, BS1 can be a communication base station that can only perform the communication task. In other implementations, BS1 can be a base station that can perform the communication task and the sensing task, such as an integrated sensing and communication base station. Thus, BS1 can realize the communication task with the UE and the sensing task with the UE as the sensing target by sending an integrated sensing and communication signal to the UE.

[0084] It should be noted that in different implementations, the sensing target can be an active device or a passive target. The active device can include a terminal device, a user equipment (UE), etc. The passive target can include a user, a car, etc.

[0085] In some embodiments, BS1 can implement the communication task with the UE by any one or more of the following waveforms: an Orthogonal Frequency Division Multiplexing (OFDM) waveform; a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform; a Discrete Fourier Transform-Spread OFDM (DFT-S-OFDM) waveform; and / or the like.

[0086] In embodiments of the present application, the communication task can be performed based on any one of the following communication protocols:

[0087] Long Term Evolution-Advanced (LTE-A) corresponding to a 4G network, New Radio (NR) corresponding to a 5G network, a cellular communication protocol corresponding to a 6G network and / or the like, a short-range communication protocol corresponding to WIFI, Bluetooth, Zigbee and / or the like.

[0088] Taking a perception task scenario as an example.

[0089] In this example, BS2 can transmit a perception beam in different directions by means of beam scanning and / or the like, and the perception beam can carry a perception signal. For example, BS2 can transmit a perception beam in the direction of a perception target (e.g., a user) by a perception link. The perception signal in the perception beam can be received by BS2 after being reflected by the user. In this way, BS2 can implement perception of the user according to the transmitted perception signal and the received reflected perception signal. For example, determine the location of the user, implement identification of the user and / or the like.

[0090] In some implementations, the perception task can be a self-generation and self-reception perception task. For example, BS2 can send a perception signal to a perception target (i.e., self-generation). BS2 can receive the perception signal reflected by the perception target (i.e., self-reception), and implement perception of the perception target according to the received perception signal (or the received perception signal and the sent perception signal).

[0091] In other implementations, the sensing task can be a self-to-other sensing task. For example, BS 2 can cooperate with other devices (e.g., UE 1, BS 2, etc.) to implement sensing of a sensing target. In this example, BS 2 can transmit a sensing signal to the sensing target (i.e., self). The other devices can receive the sensing signal reflected by the sensing target (i.e., other). In this way, the other devices or BS 2 can acquire the reflected sensing signal by signal synchronization, and implement sensing of the sensing target. This self-to-other sensing task can also be referred to as a cooperative sensing task.

[0092] In different implementations, the waveform used to implement the sensing task can be different. In some embodiments, BS 2 can implement the sensing task by using any one or more of the following waveforms: frequency modulated continuous wave (FMCW); single-carrier frequency-division multiple access (SC-FDMA); orthogonal time-frequency space (OTFS); pulse signal; OFDM; etc.

[0093] It should be noted that in some cases, the sensing signal used to implement the sensing task and the communication signal used to implement the communication task can be different. For example, the beam type, frequency range, and / or time domain range of the sensing signal and the communication signal can be different. Taking the beam type of the sensing signal and the communication signal as an example, the sensing signal can be transmitted using a radar beam, while the communication signal generally does not use a radar beam.

[0094] In this way, in the sensing system, the device (referred to as a sensing device, such as BS 2) for implementing the sensing task can be configured to have the capability of sensing (or referred to as sensing measurement). In some implementations, the sensing device can be provided with a hardware device (such as a transmitter) capable of implementing sensing to support different sensing signals. In other implementations, the modem in the sensing device can be configured to have the capability of sensing to support different sensing signals.

[0095] Correspondingly, in the communication system, the device (referred to as a communication device, such as BS 1) for implementing the communication task can be configured to have the capability of communication (or referred to as communication measurement). In some implementations, the communication device can be provided with a hardware device (such as a transmitter) capable of implementing communication to support different communication signals. In other implementations, the modem in the communication device can be configured to have the capability of communication to support different communication signals.

[0096] It can be understood that, in the case of separate deployment of the sensing device and the communication device, the communication device can only support communication measurement, but not sensing measurement. Alternatively, the communication device can support communication measurement, and support sensing measurement.

[0097] In the case of combined deployment of the sensing device and the communication device (such as an integrated sensing and communication system), the communication device can support communication measurement, and support sensing measurement.

[0098] In some cases, the sensing target is close to the device (such as a terminal device) performing the communication task. For example, the sensing target is a user, and the device performing the communication task is a terminal device of the user. When the user holds the terminal device, or when the user carries the terminal device, the sensing target is close to the device performing the communication task.

[0099] Taking the case of using the same time domain and frequency domain resource configuration and uplink and downlink configuration for the communication task and the sensing task as an example. The communication task of the terminal device and the sensing task for the sensing target (user) are performed at the same time, and the frequency domain resource configuration and uplink and downlink configuration of the communication link and the sensing link are the same. In this way, the sensing signal reflected by the user and / or the sensing signal sent by the BS 2 will also be received by the terminal device. As a result, cross-link interference between the sensing signal and the communication signal of the communication task will occur.

[0100] For example, as shown in FIG. 1, for the terminal device, the communication signal of the communication task can be received through the communication link in the process of communicating with the BS 1. In addition, the terminal device can also receive the sensing signal reflected by the user. Since the time domain and frequency domain configurations are the same, the communication signal and the sensing signal will interfere with each other, and the communication quality of the communication task will be reduced.

[0101] Based on similar reasons, the transmission of data of the communication task can also cause the decrease of the sensing task accuracy.

[0102] It should be noted that, in the above examples, the sensing target is taken as the user as an example. In other embodiments, the sensing target can also include other objects. For example, objects similar to the user, such as houses, cars, etc., which do not actively communicate. For example, a terminal device, such as another UE, which can communicate with the network device. In the case of the sensing target being another UE (such as UE 2), the BS 2 can implement sensing on the UE 2 by transmitting the sensing signal to the UE 2. In this way, the UE (such as UE 1) performing the communication task will also be interfered with the communication task due to receiving the sensing signal sent by the BS 2 to the UE 2.

[0103] It can be understood that in the above examples, the form of the UE performing the communication task can be various. For example, the UE can perform the communication task by directly communicating with the BS1. For another example, the UE can perform the communication task with the BS1 by performing the communication sensing task. The above various implementations of performing the communication task can be referred to as the UE performing a first task with the BS1.

[0104] In the above description, the UE performs the communication task while receiving the signal (e.g., the sensing signal, which can also be referred to as the first signal) of the sensing task. In some other implementations, when the UE performs the sensing task (e.g., directly receives the sensing signal sent by the sensing device or performs the cooperative sensing task), interference between two signals can occur due to the reception of the sensing signal of the other sensing task. In this application, the task performed by the UE due to the interference of the other sensing task can be referred to as the first task. The first task can include the communication task, the cooperative sensing task, and / or the integrated communication and sensing task.

[0105] In the following description, the first task is taken as the communication task. The mutual interference between the communication task and the sensing task can be referred to as the communication sensing interference.

[0106] Based on this, the technical scheme provided by the embodiments of the present application can utilize the sensing capability of the UE to cooperate with the resource configuration of the BS1 and the BS2 to avoid the cross interference of the sensing and communication links.

[0107] The scheme provided by the embodiments of the present application can be applied to the scenario where the communication task and the sensing task coexist. In some embodiments, the hardware corresponding to the communication task (e.g., the base station, BS1, etc.) can be different from the hardware corresponding to the communication task (e.g., the BS2, etc.), that is, corresponding to the configuration form of the first stage or the second stage described above. In some other embodiments, the BS1 and the BS2 can also be integrated in the same base station, that is, corresponding to the configuration form of the third stage described above. The embodiments of the present application do not limit this.

[0108] Taking the BS1 as the communication device for performing the communication task and the BS2 as the sensing device for performing the sensing task as an example.

[0109] Referring to FIG. 2, a flowchart of a communication method provided by the embodiments of the present application is shown. In this example, the scheme is applied to the first base station.

[0110] In some embodiments, the first base station can correspond to the BS1 described above. Correspondingly, the second base station can correspond to the BS2 described above. In some other embodiments, the first base station can also correspond to the BS2 for performing the sensing task, and then the second base station can correspond to the BS1. The embodiments of the present application do not limit this.

[0111] It can be understood that in some embodiments, the first base station is BS1, and the second base station is BS2. BS1 can perform a communication task with the UE. BS2 can perform a sensing task with the UE. The resources used by the communication task and the sensing task can at least partially overlap. For example, the frequency domain resources and the time domain resources used by the currently ongoing communication task can be the same as the frequency domain resources and the time domain resources used by the currently ongoing sensing task. That is, the communication task and the sensing task are currently being performed simultaneously, and the communication task and the sensing task use the same frequency.

[0112] In the present example, BS1 can perform a communication task with the UE. In the case where the communication quality of the communication task decreases, BS1 can attempt to improve the communication quality of the communication task. For example, BS1 can attempt to adjust the cell, beam, frequency band, etc. used by the communication task to attempt to improve the quality of the communication task.

[0113] In the case where BS1 is unable to improve the quality of the communication task through existing solutions, it can be indicated that the decrease in the quality of the current communication task is caused by interference from other tasks (such as the sensing task).

[0114] Therefore, BS1 can perform the following solution as shown in FIG. 2 to avoid interference of the sensing task on the communication task, and thus effectively improve the communication quality of the communication task.

[0115] It should be noted that the first base station can perform a communication task with the UE. During the execution of the process as shown in FIG. 2, the communication task between the first base station and the UE can not be interrupted. Correspondingly, during the execution of the process as shown in FIG. 2, the sensing device (such as BS2) can continue to perform the sensing task with the sensing target, or can temporarily not perform the sensing task.

[0116] As shown in FIG. 2, the solution can include:

[0117] S201, the first base station obtains the sensing capability of the UE.

[0118] For example, the first base station can obtain the sensing capability of the UE through signaling interaction between the UE.

[0119] In some embodiments, the sensing capability can include at least one of the following:

[0120] Sensing waveform; frequency domain bandwidth; time domain duration; time domain interval; guard interval; subcarrier spacing.

[0121] Specifically, in some implementations, the sensing capability can include a sensing waveform, a time domain duration, a time domain interval. In some other implementations, the sensing capability can include a sensing waveform, a frequency domain bandwidth, a time domain duration, a time domain interval, a guard interval, a subcarrier spacing.

[0122] wherein the sensing waveform is used to indicate a waveform feature in a sensing task process. The sensing waveform can include any one of the following: Orthogonal Frequency Division Multiplexing (OFDM), Frequency Modulated Continuous Wave (FMCW), Orthogonal Time Frequency Space (OTFS), Single-carrier Frequency-Division Multiple Access (SC-FDMA), pulse signal.

[0123] The frequency domain bandwidth and the time domain duration can be used to indicate relevant features corresponding to the sensing waveform. For example, taking the case that the sensing waveform includes a pulse signal. The frequency domain bandwidth can be used to indicate the maximum bandwidth of the pulse signal supported by the UE. The time domain duration can be used to indicate the pulse signal transmission interval.

[0124] As a possible implementation, the following provides a scheme implementation of a first base station acquiring the sensing capability of a UE. The scheme can include steps a1 and a2.

[0125] Step a1: The first base station sends a sensing capability request to the UE.

[0126] For example, in some embodiments, BS1 can send the sensing capability request (UE Sensing Capability Enquiry) through Radio Resource Control (RRC) signaling.

[0127] For example, taking BS1 as the first base station.

[0128] In some implementations, BS1 can send the sensing capability request to all UEs within the cell coverage of BS1 through RRC signaling respectively.

[0129] In some other implementations, BS1 can send the sensing capability request to the UE in the form of broadcast.

[0130] In this application, the first base station can send a third message, and the third message can include the sensing capability request.

[0131] Step a2: the UE sends the sensing capability information to the first base station.

[0132] For example, the sensing capability information can include UE sensing capability information.

[0133] In some embodiments, the UE supports the sensing task. The UE can feed back the sensing capability information of the UE to the BS1 in response to the sensing capability request. The sensing capability information can include the sensing capability of the UE. As described above, the sensing capability can include one or more of the sensing waveform, the frequency domain bandwidth, the time domain duration, the time domain interval, the guard interval, and the subcarrier interval corresponding to the process of the UE performing the sensing task.

[0134] In other embodiments, the UE does not support the sensing task. The UE can refuse to receive the sensing capability request, or the UE can not respond after receiving the sensing capability request, or the UE can send a message to the first base station indicating that the UE does not support the sensing capability.

[0135] In the following description, the UE supports the sensing task.

[0136] Thus, through steps a1 to a2, the first base station can know which UEs supporting the sensing task among the UEs currently performing the communication task with the first base station, and the sensing capability of each UE supporting the sensing task.

[0137] In this application, the first base station can send a fourth message, and the fourth message can include the sensing capability information.

[0138] S202: The first base station configures the UE with sensing measurement parameters.

[0139] In this application, the first base station can instruct the UE to perform sensing measurement. Through the sensing measurement, the UE can determine the existence of interference resources from the currently configured communication task resources (referred to as communication resources) and / or sensing task resources (referred to as sensing resources).

[0140] It should be noted that in the embodiments of the present application, the resources of the task (such as sensing resources, communication resources, etc.) can include resources of multiple dimensions. For example, the resources of the task can include beam resources, and / or frequency domain resources, and / or time domain resources, etc.

[0141] The sensing measurement can be performed under the instruction of the first base station.

[0142] For example, the sensing measurement parameter can be used to indicate to measure part or all of the configured communication resources.

[0143] In this way, by configuring the sensing measurement parameter to the UE, the UE can measure the configured communication resources according to the sensing measurement parameter, and thus determine the existence of the interference in the configured communication resources.

[0144] In some embodiments, the first base station can determine the sensing measurement parameter according to the currently configured sensing resources. For example, the sensing measurement parameter can be used to indicate to measure part or all of the sensing resources. In some implementations, the configured sensing resources can be obtained from the second base station.

[0145] In this way, by configuring the sensing measurement parameter to the UE, the UE can measure the configured sensing resources according to the sensing measurement parameter, and thus determine the existence of the interference in the configured sensing resources.

[0146] In some embodiments, the first base station can determine the sensing measurement parameter according to the currently configured sensing resources and the communication resources. For example, the sensing measurement parameter can be used to indicate to measure part or all of the sensing resources and / or part or all of the communication resources.

[0147] In this way, by configuring the sensing measurement parameter to the UE, the UE can measure the configured resources (e.g., at least part of the sensing resources and / or the communication resources) according to the sensing measurement parameter, and thus determine the existence of the interference in the configured resources.

[0148] In some embodiments, the sensing measurement parameter can include one or more threshold values. The one or more threshold values can correspond to the usage condition of the threshold value, and together constitute a threshold condition. The UE can determine whether to generate a corresponding measurement report according to the measurement result and the threshold condition. The measurement report can be used to indicate the existence of the interference in the resource corresponding to the currently measured sensing measurement signal.

[0149] In different implementations, the usage condition of the threshold value can be configured to the UE by the first base station, or the usage condition of the threshold value can be pre-negotiated by the UE and the first base station (e.g., by a standard protocol).

[0150] As an example, taking BS1 as the first base station. BS1 can configure a sensing measurement parameter to each UE supporting the sensing task, respectively. The sensing measurement parameter can be used to indicate the UE to perform the measurement of the sensing task. In some implementations, the sensing measurement parameter can be included in the first message.

[0151] In some embodiments, the sensing measurement parameter can include at least one of: a type of sensing measurement signal, a sensing measurement quantity, a sensing measurement interval, a sensing measurement threshold, a sensing interference quantity.

[0152] The following are described respectively.

[0153] The type of sensing measurement signal is used to indicate the measurement object in the sensing measurement process of the UE.

[0154] In some implementations, the type of sensing measurement signal can include a measurement reference signal in the communication task process. For example, the type of sensing measurement signal can include one or more of the following: Synchronization Signal Block (SSB), Channel State Information-Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), Signaling Reference Signal (SRS), etc.

[0155] In other implementations, the type of sensing measurement signal can include a reference signal in the sensing task process. For example, the type of sensing measurement signal can include one or more of the following: a reference signal based on sensing waveform, i.e., OFDM, FMCW, OTFS, SC-FDMA, pulse signal. It can also be a sensing integrated signal, such as an OFDM and / or OTFS-based sensing integrated signal.

[0156] The sensing measurement quantity is used to indicate the specific parameter that needs to be measured after the UE receives the type of sensing measurement signal.

[0157] In some implementations, the sensing measurement quantity can include at least one of: a sensing signal strength, a sensing signal-to-interference ratio, a sensing interference time offset, a sensing interference duration, a sensing interference period, a sensing interference duty cycle, a sensing interference quantity, a block error rate, etc. The sensing signal strength is used to indicate the signal strength of the received sensing signal; the sensing signal-to-interference ratio is used to indicate the ratio of the sensing signal to the noise floor and other interference.

[0158] The sensing measurement interval indicates the start and end time of the sensing measurement. In some embodiments, there is no uplink and downlink transmission within the sensing measurement start and end time. That is, during the execution of the sensing measurement, the UE can temporarily stop the communication task according to the sensing measurement interval, thereby ensuring the measurement accuracy.

[0159] Take the sensing waveform as an example. The sensing measurement interval can include the duration of performing the sensing measurement, the repetition period, and the like.

[0160] The sensing measurement threshold is used to indicate the sensing measurement related threshold. For example, in some embodiments, the sensing measurement threshold can include a threshold for starting measurement and / or a threshold for generating a sensing measurement report. The threshold can be a threshold for the sensing measurement quantity.

[0161] In different implementations, the threshold for generating a sensing measurement report can include one or more. Take the threshold for generating a sensing measurement report including multiple as an example. Different thresholds correspond to generating different measurement reports.

[0162] Take the sensing measurement quantity including the block error rate as an example. The sensing measurement threshold can include one or more thresholds corresponding to the block error rate.

[0163] In some embodiments, the configuration of the sensing measurement threshold can be related to the waveform and the like parameters of the sensing task. For example, take the sensing signal waveform as an example. The sensing measurement threshold can be related to the amplitude of the pulse, the duration of the pulse, and the time interval of the pulse. Correspondingly, the sensing measurement threshold can include the amplitude of the start detection, the amplitude threshold or condition for generating the measurement report, and the like.

[0164] The sensing interference quantity indicates the number of sensing interference that can exist at the current location of the UE. Take an example of a base station simultaneously performing at most one sensing task. There can be multiple base stations (such as multiple BS2) simultaneously performing sensing tasks on the UE at the current location of the UE. In this way, the sensing interference quantity can be used to indicate the number of sensing interference that can exist at the current location of the UE. Correspondingly, the UE can perform corresponding processing on the data obtained during the measurement according to the sensing interference quantity, so as to separate one or more sensing interference.

[0165] The following provides an example of a scheme for BS1 to configure sensing measurement parameters to UE. The process can include steps b1 to b2.

[0166] Step b1: BS1 sends sensing measurement parameter indication information to UE.

[0167] In some embodiments, the sensing measurement parameter indication information can be included in the RRC reconfiguration (RRC Reconfiguration) message sent by BS1 to UE. The RRC reconfiguration message can include the above-mentioned measurement configuration parameters. In some implementations, the measurement parameter indication information can be included in the first message.

[0168] Step b2: UE sends confirmation information to BS1.

[0169] In this example, the UE receives the sensing measurement parameter indication information, and obtains the measurement configuration parameter therein. The UE can send the confirmation information to the BS1, so that the BS1 determines that the UE has received the measurement configuration parameter.

[0170] In some embodiments, the confirmation information can correspond to ACK information. After receiving the sensing measurement parameter indication information and obtaining the measurement configuration parameter therein, the UE sends an RRC Reconfiguration Complete message to the BS1. The RRC Reconfiguration Complete message can include ACK information.

[0171] Correspondingly, in some other embodiments of the present application, the UE can send a message carrying NACK information to the BS1 in the case that the UE does not receive the sensing measurement parameter indication information within a preset time length, or cannot normally obtain the measurement configuration parameter after receiving the sensing measurement parameter indication information, so that the BS1 knows that the sensing measurement configuration fails. Correspondingly, the BS1 can trigger the sensing measurement reconfiguration, such as repeating the S601.

[0172] Therefore, by implementing the scheme as shown in FIG. 6, the BS1 can complete the configuration of the sensing measurement parameter of the UE. Correspondingly, the UE can perform corresponding measurement according to the received sensing measurement parameter, thereby determining whether there is a communication sensing interference of the sensing task to the communication task, and the time domain characteristics of the communication sensing interference and the like.

[0173] It should be noted that in the above example, the configuration of the sensing measurement parameter is described in detail.

[0174] In some other embodiments, the BS1 can also configure the interference beam information of the sensing task related to the sensing interference beam of the UE in addition to the configuration of the sensing measurement parameter of the UE.

[0175] In this example, the BS1 can communicate with the BS2 through a wired or wireless link before performing the S202, thereby obtaining the sensing task resource configuration parameter of the BS2 performing the sensing task.

[0176] The sensing task resource configuration parameter can include at least one of the following: a beam set of the sensing task, a time slot configuration, a start and end time, a bandwidth, a waveform parameter, and the like. For example, the BS1 can obtain the sensing waveform parameter, the sensing beam information, the sensing mode, and the sensing transmission and reception time configuration information through communication with the BS2.

[0177] The perception waveform parameter includes a perception waveform, a perception signal duration, a perception time interval, a bandwidth, and the like. The perception beam set includes a set of perception beam indications or indexes for a perception task. The time slot configuration of the perception task includes time slots occupied by the perception beam. The perception beam information includes a perception beam transmission period, a corresponding coverage area of the perception beam, a perception beam index, and a perception beam time-frequency resource configuration. The perception mode includes a self-receiving mode and a self-to-other receiving mode. In the self-receiving mode, a transmission end and a receiving end of the perception task are the same device. In the self-to-other receiving mode, the transmission end and the receiving end of the perception task are different. The perception transceiver time configuration includes a time configuration of a transmission and a reception of the perception base station, and the time configuration is related to a beam direction, a perception area, and a perception task. The perception task includes positioning, tracking, imaging, pattern recognition, and the like.

[0178] In this way, the BS1 can determine the beam of the communication task covering the current location of the UE according to the current cell where the UE is located. The BS1 can also determine the location of the UE relative to the BS1 according to the signal strength and the like of the communication task. According to the current location of the UE, the BS1 can determine the information of the perception beam used by the BS2 and the UE for the perception task. The perception beam is an interference beam of the perception task for the communication task. For example, the interference beam can be a beam of the perception task covering the current location of the UE.

[0179] In this example, the BS1 can send the information of the interference beam of the perception task (such as a beam index and the like) to the UE, so that the UE performs the perception measurement on the interference beam.

[0180] In S203, the UE performs the perception measurement according to the perception measurement parameter, and obtains a perception measurement result.

[0181] It can be understood that the UE can continue the communication task during the perception measurement.

[0182] In some embodiments, the first base station can send a perception measurement signal during the perception measurement of the UE.

[0183] In some implementations, the beam resource and / or the frequency domain resource and / or the time domain resource used by the perception measurement signal sent by the first base station can be the same as the perception resource used for the perception task. In this way, the UE can receive the perception measurement signal while receiving the communication signal of the communication task. The UE can determine whether the current perception measurement signal interferes with the communication signal according to the received perception measurement signal and the communication signal.

[0184] For example, in some embodiments, the UE can perform the sensing measurement according to the sensing measurement parameters for each beam in the sensing task. When the result of the sensing measurement meets the threshold for generating the measurement report (e.g., the sensing measurement threshold), the UE can generate the corresponding sensing measurement report.

[0185] In other embodiments, taking the example of the BS1 configuring the UE with the information of the interference beam, the UE can perform the sensing measurement according to the sensing measurement parameters for the interference beam. When the result of the sensing measurement meets the threshold for generating the measurement report (e.g., the sensing measurement threshold), the UE can generate the corresponding sensing measurement report.

[0186] In this example, the UE can perform the sensing measurement according to the type of the sensing measurement signal, the sensing measurement quantity, and the sensing measurement interval in the sensing measurement parameters to obtain the sensing measurement result. The sensing measurement result is the result of measuring the sensing measurement quantity for the type of the sensing measurement signal.

[0187] As a possible implementation, the type of the sensing measurement signal includes a sensing reference signal, the sensing reference signal includes an SSB, a CSI-RS, a DMRS, and a pulse reference signal, and the sensing measurement quantity includes a sensing signal-to-interference ratio.

[0188] In the process of performing the S203, the UE can separate the radar pulse from the type of the sensing measurement signal based on the sensing capability of the UE and the prior information of the sensing interference provided by the base station (e.g., the BS1).

[0189] Specifically, the UE separates one or more pulse signals based on the amplitude of the pulse, the time interval of the pulse, and the duration of the pulse. The base station (e.g., the BS1) can provide the UE with the prior information of the duration of the pulse and the time interval of the pulse of the sensing BS.

[0190] Taking a continuous frequency modulation wave as an example, the UE separates the sensing signal from the type of the sensing measurement signal based on the sensing capability of the UE and the prior information provided by the base station. Specifically, the base station can provide the UE with the prior information of the configuration of the continuous frequency modulation wave of the sensing BS, and the UE calculates the spectral information of the corresponding continuous frequency modulation wave based on the prior information. The spectral information includes distance spectrum, velocity spectrum, angle spectrum, distance-velocity spectrum, distance-velocity-angle spectrum, etc. Taking the distance spectrum as an example, the UE can obtain the distance spectrum information by performing a fast time Fourier transform on the type of the sensing measurement signal that has passed through an analog-to-digital converter, and the one or more components with the largest amplitude are taken as the sensing signal and the remaining components are taken as the interference. Thus, the sensing signal-to-interference ratio is calculated.

[0191] In some embodiments of the present application, the BS1 can send one or more sensing measurement signals to the UE for sensing measurement in the process of UE measurement. Thus, the UE can perform the measurement corresponding to the sensing measurement configuration through the sensing measurement signal.

[0192] S204, the UE generates a sensing measurement report according to the sensing measurement result.

[0193] For example, the UE can generate a corresponding sensing measurement report according to the sensing measurement result and the sensing measurement threshold in the sensing measurement parameter when the sensing measurement result meets the sensing measurement threshold.

[0194] In the present application, the sensing measurement report can include at least one of the following:

[0195] The sensing measurement result, the information corresponding to the communication sensing interference, the information of the sensing beam used by the sensing task, and the base station information corresponding to the sensing task.

[0196] In some embodiments, taking the sensing signal-to-interference ratio as an example, the sensing measurement threshold includes one or more thresholds corresponding to the sensing signal-to-interference ratio.

[0197] The UE can generate a sensing measurement report when the sensing signal-to-interference ratio is greater than the corresponding sensing measurement threshold. The sensing measurement report can be used to indicate the existence of communication sensing interference.

[0198] In combination with the description in S202, the sensing measurement threshold can be configured by the first base station to the UE. The use condition corresponding to the sensing measurement threshold (such as generating a report when the threshold is greater, or generating a report when the threshold is smaller, etc.) can be pre-negotiated or configured by the first base station to the UE.

[0199] Optionally, the sensing measurement report can include the sensing measurement result, such as the sensing signal-to-interference ratio, the sensing interference signal strength, the interference time slot, the time slot offset, etc.

[0200] Taking the sensing measurement quantity including the block error rate and the sensing measurement threshold including the threshold (such as 10%, 15%) corresponding to the block error rate as an example, the actual threshold can be different. When the sensing signal-to-interference ratio is greater than different thresholds (such as threshold a, threshold b, threshold c, etc.), the UE can correspondingly generate different sensing measurement reports.

[0201] For example, in some implementations, the UE can generate a sensing measurement report A according to the measured block error rate being greater than 10% or 15%.

[0202] In other implementations, the UE can generate a sensing measurement report B according to the measured block error rate being greater than 10% and the communication interference suppression method being unable to significantly eliminate the interference.

[0203] In some implementations, the UE can generate the measurement report C according to the measured block error rate being greater than 10% and less than 15%.

[0204] In some implementations, the UE can generate the measurement report D according to the measured block error rate being greater than 15%.

[0205] In some implementations, the UE can generate the awareness measurement report E according to the measured block error rate being greater than 15% and still being greater than 10% after being processed by the communication interference suppression manner.

[0206] In some embodiments, the information corresponding to the communication awareness interference can further indicate time domain information of the existing interference, for example, a time period (e.g., a first time period) in which the communication awareness interference exists.

[0207] In some implementations, the information corresponding to the communication awareness interference can indicate time domain information of the existing interference, for example, a time period (e.g., a first time period) in which the communication awareness interference exists.

[0208] In this application, based on the information corresponding to the communication awareness interference, the BS1 adjusts the time domain resources of the communication task or the awareness task, for example, no longer uses the first time period for the communication task or the awareness task. Thus, the communication awareness interference in the first time period is avoided.

[0209] In some implementations, the information corresponding to the communication awareness interference can indicate beam information of the existing interference, for example, a communication beam (e.g., a first beam) and / or an awareness beam (e.g., a second beam) in which the communication awareness interference exists.

[0210] In this application, based on the information corresponding to the communication awareness interference, the BS1 adjusts the beam resources of the communication task or the awareness task, for example, no longer uses the first beam for the communication task or no longer uses the second beam for the awareness task. Thus, the communication awareness interference in the direction corresponding to the above-mentioned beams is avoided.

[0211] In some implementations, the information corresponding to the communication awareness interference can indicate frequency band information of the existing interference, for example, a first frequency band in which the communication awareness interference exists.

[0212] In this application, based on the information corresponding to the communication awareness interference, the BS1 adjusts the frequency domain resources of the communication task or the awareness task, for example, no longer uses the first frequency band for the communication task or the awareness task. Thus, the communication awareness interference in the first frequency band is avoided.

[0213] In the following example, the information of the communication awareness interference indicates the time domain information of the existing interference.

[0214] For example, the information of the communication-aware interference can comprise any one or more of:

[0215] a start time and an end time of the communication-aware interference, a duration of the communication-aware interference, a signal strength of the communication-aware interference, a periodicity of the communication-aware interference, a duty cycle of the communication-aware interference, an identification of a time unit in which the communication-aware interference occurs.

[0216] For example, the time information of the communication-aware interference comprises an identification of a time unit in which the communication-aware interference occurs.

[0217] It can be understood that, in time domain, the communication task and the sensing task can be respectively performed with the UE based on a plurality of time units. In some implementations, the one time unit can correspond to one time slot (Slot) or a single symbol period, a duration.

[0218] Referring to FIG. 3, a schematic diagram of a time unit distribution is shown. The UE can perform the communication task with the BS1 in one or more of the time unit 1 to the time unit 5. The UE can also perform the sensing task with the BS2 in one or more of the time unit 1 to the time unit 5.

[0219] For example, the BS1 can perform the communication task with the UE in each of the time unit 1 to the time unit 5. The BS2 can perform the sensing task with the UE in the time unit 2 and the time unit 4.

[0220] In this example, the UE can perform the measurement of the communication-aware interference for each time unit, and determine the information of the time unit in which the communication-aware interference exists according to the sensing measurement result.

[0221] For example, the UE can determine that the sensing measurement result measured and obtained in the time unit 2 and the time unit 4 satisfies the sensing measurement threshold. In this way, the UE can determine that the communication-aware interference exists in the time unit 2 and the time unit 4.

[0222] Therefore, the UE can carry the information of the time unit 2 and the time unit 4 in the sensing measurement report. Further, the BS1 is aware that the communication-aware interference exists in the time unit 2 and the time unit 4.

[0223] It should be noted that, as shown in the example of FIG. 3, the time unit 2 and the time unit 4 in which the UE performs the sensing task both exist the communication-aware interference. This result is determined by the UE according to the sensing measurement process. In other implementations, one or more time units in which the UE performs the sensing task can also not satisfy the sensing measurement threshold, i.e., there is no sensing measurement interference.

[0224] In some embodiments, the sensing measurement report can comprise information of a sensing beam in which the communication-aware interference exists.

[0225] For example, after measuring each sensing beam, the UE can obtain the sensing measurement result of each sensing beam. The UE can determine the information of the sensing beam with the communication sensing interference according to the sensing measurement threshold. For example, the information of the sensing beam can include the beam identifier, the beam index, and the like of the sensing beam. In this way, the UE can send the information of the sensing beam with the communication sensing interference to the BS1 in the sensing measurement report.

[0226] In some embodiments, the sensing measurement report can include the base station information corresponding to the sensing task with the communication sensing interference. For example, the UE can determine the BS2 as the base station corresponding to the sensing task with the communication sensing interference in the case that the UE determines that there is a sensing beam satisfying the sensing measurement threshold in the sensing beam sent by the BS2. In this way, the UE can send the identifier information of the BS2 to the BS1 in the sensing measurement report.

[0227] In the following examples, the sensing measurement report includes the information corresponding to the communication sensing interference.

[0228] S205, the UE sends the sensing measurement report to the first base station.

[0229] For example, the UE can send the sensing measurement report to the BS1 after generating the sensing measurement report.

[0230] As described in S204, the sensing measurement report can include the information corresponding to the communication sensing interference. In some embodiments, the information corresponding to the communication sensing interference can be used to indicate the time domain information of the communication sensing interference.

[0231] In some embodiments, the UE can periodically report the generated sensing measurement report.

[0232] In some embodiments, the BS1 sends a request signaling, and the UE reports the sensing measurement report based on the request.

[0233] In another embodiment, the UE can send the sensing measurement report to the BS1 after generating the sensing measurement report.

[0234] It should be noted that in another embodiment of the present application, the UE can also send the related information for solving the interference to the first base station.

[0235] In some embodiments, the UE may send measured beam information and / or time-domain information and / or frequency-domain information of the communication task used without interference to the first base station. It is understood that when the UE performs the measurement in S203 above, it may be measuring some or all of the communication resources configured by the first base station for the communication task. While some communication resources may have cross-link interference, some configured communication resources may not have cross-link interference. In this case, the UE may send the measured resources without cross-link interference to the first base station.

[0236] In other embodiments, the UE may send unmeasured communication resources to the first base station. In this example, the UE may send configured, unmeasured communication resources to the first base station. In some implementations, the unmeasured communication resources may be resources already configured to the UE by the first base station but not included in the measurement resources indicated by the sensing measurement parameters configured by the first base station. In this way, the UE can exclude resources where interference is determined to exist and report resources that may not have interference to the first base station.

[0237] In other embodiments, the UE may send both of the above items to the first base station together.

[0238] In different implementations of this application, the sensing measurement report and interference mitigation information can be sent to the first base station via the same signaling. Correspondingly, the second message may include the sensing measurement report and interference mitigation information. The second message may correspond to a single air interface signaling message.

[0239] Alternatively, the sensing measurement report and related interference resolution information can be sent to the first base station via different signaling. Correspondingly, the second message may include the sensing measurement report and related interference resolution information. The second message may correspond to a combination of two or more air interface signaling messages.

[0240] Alternatively, the second message may include only one of the aforementioned sensing measurement reports or information related to resolving interference.

[0241] S206. The first base station performs interference suppression processing based on the sensing measurement report.

[0242] In some embodiments, the first base station determines that cross-link interference exists in a first time period based on information reported by the UE. For example, the first base station can determine that interference exists in the first time period based on the measurement report reported by the UE.

[0243] In some implementations, the first base station can adjust the time-domain resources used for communication tasks with the UE. The adjusted time-domain resources do not include the first time period where interference may occur. This allows the communication task to avoid the first time period where interference may occur.

[0244] In some implementations, the first base station can adjust the time domain resource for the communication task with the UE. For example, the first base station can update the time domain resource for the communication task with the UE based on the information reported by the UE. The updated time domain resource for the communication task does not include the first time period in which the interference exists. In another example, the first base station can send the information of the time period in which the interference exists to the base station performing the sensing task, so that the base station performing the sensing task can adjust the time domain resource for the sensing task. The adjusted time domain resource for the sensing task does not include the first time period in which the interference exists.

[0245] It can be understood that, when the first base station determines that there is no (or possibly no) interference in the configured time domain resource according to the information reported by the UE (such as the information related to solving the interference), the first base station can perform the communication task with the UE on the time domain resource in which there is no (or possibly no) interference according to the time domain information indicated by the information related to solving the interference, or instruct the terminal device / base station performing the sensing task to perform the communication task with the UE on the time domain resource in which there is no (or possibly no) interference. The time domain resource in which there is no interference can be the time domain resource in which it is determined that there is no interference after measurement. The time domain resource in which there can be no interference can be the configured time domain resource without measurement.

[0246] In some implementations, the first base station can adjust the time domain resource for the communication task with the UE. For example, the first base station can update the time domain resource for the communication task with the UE based on the information reported by the UE. The updated time domain resource for the communication task does not include the first time period in which the interference exists. In another example, the first base station can send the information of the time period in which the interference exists to the base station performing the sensing task, so that the base station performing the sensing task can adjust the time domain resource for the sensing task. The adjusted time domain resource for the sensing task does not include the first time period in which the interference exists.

[0247] In some implementations, the first base station can adjust the frequency domain resource for the communication task with the UE. The adjusted frequency domain resource does not include the first frequency band in which the interference exists. Thus, the communication task is performed in a frequency band in which there is no interference.

[0248] In some implementations, the first base station can adjust the time domain resource for the communication task with the UE. For example, the first base station can update the time domain resource for the communication task with the UE based on the information reported by the UE. The updated time domain resource for the communication task does not include the first time period in which the interference exists. In another example, the first base station can send the information of the time period in which the interference exists to the base station performing the sensing task, so that the base station performing the sensing task can adjust the time domain resource for the sensing task. The adjusted time domain resource for the sensing task does not include the first time period in which the interference exists.

[0249] It can be understood that, in a case where the first base station determines, according to the information reported by the UE (such as the information related to solving the interference), that there is no (or there can be no) interference in the configured other frequency domain information, the first base station can perform the communication task with the UE on the frequency domain resource in which there is no (or there can be no) interference according to the frequency domain information indicated by the information related to solving the interference, or instruct the terminal device / base station performing the sensing task to perform the communication task with the UE on the frequency domain resource in which there is no (or there can be no) interference. The configured frequency domain resource in which there is no interference can be a frequency domain resource in which it is determined that there is no interference after measurement. The configured frequency domain resource in which there can be no interference can be a configured frequency domain resource without measurement.

[0250] In some other embodiments, it is assumed that the first base station determines, according to the information reported by the UE, that the first beam performing the communication task has cross-link interference. For example, the first base station can determine, according to the measurement report reported by the UE, that the first beam has interference.

[0251] In some implementations, the first base station can adjust the beam resource used for the communication task with the UE. The adjusted beam resource does not include the first beam having interference. In this way, the communication task is performed by avoiding the first beam having interference. In some implementations, the first base station can determine, from the information related to solving the interference reported by the UE, that the third beam has no or can have no interference. In this way, the first base station can use the beam resource including the third beam to perform the subsequent communication task with the UE. The third beam can be a beam having no interference determined by the UE through measurement, or the third beam can be a configured beam for the communication task without measurement by the UE.

[0252] In some other implementations, the first base station can adjust or assist in adjusting the beam resource performing the sensing task.

[0253] For example, the first base station can update the beam resource performing the sensing task for the terminal device performing the sensing task, and the adjusted beam resource performing the sensing task does not include the beam (such as the second beam) having interference. The second beam can be a beam performing the sensing task. The position pointed to by the second beam can be the same as or close to the position pointed to by the first beam performing the communication task. It can be understood that, the first base station can determine the information of the sensing beam (such as the information including the second beam) being used through the sensing task resource configuration parameter obtained from the BS2 in the foregoing example. For the sensing task initiated by the terminal device, the sensing resource can be configured to the terminal device by the first base station, and therefore the first base station can know the sensing resource including the second beam.

[0254] For another example, the first base station can send the information of the frequency band with interference to the base station performing the sensing task (e.g., BS2), so that the base station performing the sensing task can adjust the beam resource of the sensing task, and the adjusted beam resource of the sensing task does not include the second beam with interference.

[0255] The following will be described in combination with the drawings, and the specific implementation of the first base station adjusting subsequent communication according to the information reported by the UE will be exemplified.

[0256] In some embodiments, the interference suppression processing can include that the BS1 adjusts the resource configuration used for the communication task between the BS1 and the UE. The adjusted resource configuration of the communication task does not include the time period with the communication sensing interference.

[0257] For example, the information corresponding to the communication sensing interference indicates that the time unit 2 and the time unit 4 have the communication sensing interference.

[0258] The BS1 can adjust the resource configuration for the communication task with the UE. For example, the BS1 can adjust the time domain resource configuration for the communication task with the UE. The adjusted time domain resource of the communication task does not include the time unit 2 and the time unit 4 in FIG. 3.

[0259] The BS1 can send the adjusted resource configuration to the UE, so that the UE can continue the communication task with the BS1 according to the adjusted resource configuration.

[0260] For example, the BS1 can configure the adjusted resource of the communication task to the UE through the Radio Resource Control Reconfiguration (RRC Reconfiguration) signaling, the Medium Access Control Layer Control Element (MAC CE), the Downlink Control Information (DCI), or the like.

[0261] In this way, since the adjusted communication task is no longer performed in the time unit 2 and the time unit 4, the sensing task will not interfere with the communication task. Thus, the communication quality of the sensing task and the communication task can be improved.

[0262] It can be understood that in the above embodiments, a plurality of mechanisms for the UE to report the interference-related information to the first base station are provided. For example, the UE can report a measurement report to the first base station. For another example, the UE can report the interference-related information to the first base station. In subsequent embodiments of the present application, the content reported by the UE and the processing mechanism of the first base station can also refer to the foregoing examples, and specific details will not be repeated here. In the following description, the UE reports a measurement report, and the first base station adjusts the resource for interference suppression according to the measurement report as an example.

[0263] In other embodiments, the processing of interference suppression can include that the BS1 sends information corresponding to the communication-perception interference to the second base station (such as BS2). So that the BS2 adjusts the perception resource configuration used for the perception task between the UE. The adjusted perception resource configuration does not include the time period in which the communication-perception interference exists.

[0264] In combination with the example in FIG. 3, it is taken as an example that the information corresponding to the communication-perception interference indicates that the time unit 2 and the time unit 4 exist communication-perception interference.

[0265] In some embodiments, the information corresponding to the communication-perception interference can include information corresponding to the time unit 2 and the time unit 4.

[0266] For example, the BS1 can send the identification of the time unit 2 and the time unit 4 to the BS2. For another example, the BS1 can send the start time and the end time of the time unit 2 and the time unit 4 to the BS2.

[0267] Therefore, the BS2 can adjust the resource configuration for the perception task with the UE according to the information corresponding to the time unit 2 and the time unit 4. For example, the BS2 adjusts the time-domain resource configuration for the perception task with the UE according to the information corresponding to the time unit 2 and the time unit 4. The adjusted time-domain resource for the perception task does not include the time unit 2 and the time unit 4 in FIG. 3.

[0268] In this way, since the adjusted perception task is no longer performed in the time unit 2 and the time unit 4, the perception task will not interfere with the communication task. Therefore, the communication quality of the perception task and the communication task can be improved.

[0269] In this example, it is taken as an example that the time unit 2 and the time unit 4 exist communication-perception interference as shown in FIG. 3.

[0270] In some embodiments, BS1 can also flexibly adjust the time units of the communication task according to the distribution of the time units in which the communication-aware interference exists. For example, the communication-aware interference exists in time unit 2 and time unit 4. BS1 can adjust the time units of the communication task to be time units with odd identifiers. For example, the communication task is only performed in time unit 1, time unit 3, time unit 5, and the like. In this way, even if the UE continues to receive the awareness signal in the subsequent even time units, the communication quality will not be reduced due to the reception of the data of the communication task in the same time unit.

[0271] In some embodiments, the information corresponding to the communication-aware interference can include information of the awareness beam in which the communication interference exists. For example, the information of the awareness beam can include index information of the awareness beam, and the like.

[0272] In this way, BS2 can adjust the beam configuration for the awareness task with the UE according to the information of the awareness beam in which the communication interference exists. The adjusted beam used for the awareness task does not include the awareness beam in which the communication interference exists.

[0273] In this way, since BS2 no longer uses the beam in which the communication-aware interference exists to perform the awareness task with the UE, the UE will not receive the awareness task in time unit 2 and time unit 4. Furthermore, the UE will not be affected by the quality of the communication task due to the reception of the awareness task.

[0274] Referring to FIG. 4, an interaction flow diagram of a communication method provided by an embodiment of the present application is shown. In this embodiment, BS1 is a first base station used for performing a communication task with a UE, and BS1 has an awareness measurement capability (for example, BS1 has the capability of transmitting an awareness measurement signal). BS2 is a second base station used for performing an awareness task with the UE.

[0275] In this example, the UE can perform a first task (for example, a communication task) with BS1. The UE can also receive a first signal. The first signal can correspond to a first awareness task. The first signal can be a signal directly transmitted by BS2 and / or a signal reflected by an awareness target (for example, a user) near the UE when BS2 performs the first awareness task with the UE or the awareness target.

[0276] In this way, BS1 can monitor the signal quality of the communication task during the performance of the communication task with the UE. When the signal quality of the communication task decreases, BS1 can attempt to adjust the current communication task according to the existing scheme to improve the signal quality of the communication task.

[0277] In the case that BS1 is unable to improve the quality of the communication task by itself, the sensing measurement of the communication system can be triggered. For example, in this case, the sensing measurement corresponding to S401, S402 and the subsequent processing can be triggered.

[0278] In some other implementations, BS1 can trigger the sensing measurement of the communication system when the signal quality of the current ongoing communication task is lower than a preset threshold.

[0279] As shown in FIG. 4, the scheme can include:

[0280] S401, BS2 sends the sensing task parameter to BS1.

[0281] In combination with the description in S202, in some embodiments, BS1 can obtain the sensing task parameter of BS2 before configuring the sensing measurement parameter of UE.

[0282] The sensing task parameter can include at least one of the following: sensing waveform parameter, sensing beam information, sensing mode, sensing transmission-reception time configuration information.

[0283] In some embodiments, BS1 can periodically obtain the sensing task parameter sent by BS2. In some other embodiments, BS1 can send corresponding request information to BS2 when the communication system needs to perform the sensing measurement, so as to synchronize the sensing task parameter from BS2 to BS1 according to the request information.

[0284] S402, BS1 sends the UE sensing capability request to UE. The sensing capability request is also the UE sensing capability request in the foregoing description.

[0285] S403, UE sends the UE sensing capability information to BS1. The sensing capability information is also the UE sensing capability information in the foregoing description.

[0286] For example, the sensing capability information can include the sensing capability. The sensing capability of UE can include at least one of the following:

[0287] Sensing waveform; frequency domain bandwidth; time domain duration; time domain interval; guard interval; subcarrier spacing.

[0288] S404, BS1 sends the sensing measurement parameter indication information to UE.

[0289] S405, UE sends the confirmation information to BS1.

[0290] In some implementations of the present example, in combination with the description in FIG. 2, BS1 can determine the sensing measurement parameter indication information according to at least one of the following: the sensing task parameter obtained in S401, the sensing capability information obtained in S403, the communication resource in which BS1 is currently communicating with the UE for the communication task and / or the communication resource that has been configured for the UE. In other implementations, the sensing measurement parameter can be determined according to the first task and / or the configured resource of the first sensing task.

[0291] In this way, BS1 can inform the UE of the sensing measurement parameter through the sensing measurement parameter indication information according to the parameters that have been obtained. In some implementations, the sensing measurement parameter can correspond to the beam and / or frequency domain and / or time domain information that needs to be measured in the subsequent sensing measurement process of the UE. It can be understood that since BS1 has obtained the communication resource, the sensing resource and the sensing capability of the UE, BS1 can configure the sensing measurement parameter according to the above information. For example, the resource that needs to be measured indicated by the sensing measurement parameter can correspond to the resource included in: the configured communication resource and / or the sensing resource and / or the sensing capability range of the UE and / or the preconfigured resource.

[0292] For example, in some implementations, the resource that needs to be measured corresponding to the sensing measurement parameter includes the configured communication resource. Through the configuration of this sensing measurement parameter, BS1 can instruct the UE to measure the configured communication resource to determine the information of the resource in the configured communication resource that has interference.

[0293] For example, in some implementations, the resource that needs to be measured corresponding to the sensing measurement parameter includes the configured sensing resource. Through the configuration of this sensing measurement parameter, BS1 can instruct the UE to measure the configured sensing resource to determine the information of the sensing resource in the configured sensing resource that has interference to the communication task.

[0294] For example, in some implementations, the resource that needs to be measured corresponding to the sensing measurement parameter includes the resource within the sensing capability range of the UE. Through the configuration of this sensing measurement parameter, BS1 can instruct the UE to measure the resource within the sensing capability range of the UE to determine the information of the sensing resource within the sensing capability of the UE that has interference to the communication task.

[0295] In some implementations, the sensing measurement parameter can be preconfigured.

[0296] For example, the sensing measurement parameter included in the sensing measurement parameter indication information can include at least one of the following:

[0297] The type of sensing measurement signal, the sensing measurement quantity, the sensing measurement interval, the sensing measurement threshold, and the number of sensing interference.

[0298] Thus, by configuring the sensing measurement parameter indication information, the UE can generate a corresponding first measurement report if the measurement result satisfies at least one threshold condition indicated by the sensing measurement parameter indication after performing the subsequent sensing measurement.

[0299] In some implementations, the threshold value can be indicated by the sensing measurement parameter indication. In other implementations, the threshold value and the condition corresponding to the threshold value can be configured by the BS1 synchronously or asynchronously.

[0300] S406, the BS1 sends a sensing measurement signal to the UE.

[0301] S407, the UE sends a sensing measurement report to the BS1.

[0302] For example, the UE can perform sensing measurement according to the configured sensing measurement parameter based on the sensing measurement signal. It can be understood that in this example, the BS1 has sensing measurement capability. That is, the BS1 can send a signal for sensing measurement, which has the same type and / or resource configuration as the sensing signal. In this way, the BS1 can send a measurement signal simulating the sensing signal to the UE while the UE continues to perform the communication task, so that the UE determines whether there is interference to the signal of the ongoing communication task according to the received measurement signal. In some implementations, the type and / or resource configuration of the sensing measurement signal can correspond to the sensing measurement quantity that needs to be measured indicated by the sensing measurement parameter configured by the BS1 to the UE.

[0303] As a specific example, in some embodiments, the UE can perform sensing measurement for each time unit respectively.

[0304] The sensing measurement report can include at least one of the following: sensing measurement result, information corresponding to the communication sensing interference, information of the sensing beam used by the sensing task, and information of the base station corresponding to the sensing task.

[0305] In different embodiments, the BS1 can perform the following S408 or S409 to avoid communication sensing interference between the communication task and the sensing task and improve the communication quality.

[0306] S408, the BS1 sends an adjusted communication task resource to the UE.

[0307] In this example, the BS1 can adjust the communication task resource according to the sensing measurement report. For example, adjust the time domain resource in the communication task process, so that the time domain resource of the adjusted communication task does not include the time period in which the communication sensing interference exists.

[0308] The BS1 can configure / updates the adjusted communication task resource to the UE, so as to perform the communication task with the UE through the adjusted communication task resource.

[0309] S409, BS1 sends the sensing measurement report to BS2. In some embodiments, BS1 can determine the adjusted sensing task resource according to the information reported by the UE. Thus, in this S409, BS1 can send the adjusted sensing task resource to BS2.

[0310] S410, BS2 performs the sensing task using the adjusted sensing task resource.

[0311] In this example, BS1 can send all or part of the information in the sensing measurement report to BS2, so as to facilitate BS2 to adjust the resource configuration in the sensing task.

[0312] The adjusted resource configuration of the sensing task does not include the time period in which there is communication sensing interference, and / or, the adjusted resource configuration of the sensing task does not include the beam in which there is communication sensing interference, and / or, the adjusted resource configuration of the sensing task does not include the frequency point in which there is communication sensing interference.

[0313] Thus, in the process of performing S410, BS2 can perform the sensing task with the UE according to the adjusted sensing task resource, thereby avoiding interference with the communication task and improving communication quality. When BS2 performs the sensing task with other UEs (such as UE2), due to the adjustment of the sensing task resource, the UE performing the communication task will not be interfered with even if it receives the sensing signal sent by BS2.

[0314] It can be understood that in the above description of FIG. 4, BS1 performs the communication task with the UE, and BS2 performs the sensing task with the sensing target. In other embodiments, when BS1 has sensing measurement capability, the BS1 can be an integrated sensing and communication device. That is, BS1 can also be used to perform the sensing task with the UE. In this example, BS1 performs the sensing task with the UE. BS2 performs another sensing task with the sensing target near the UE. When the time domain and frequency domain resources of the two sensing tasks overlap, mutual interference between the sensing tasks can also occur. Similar to the example of the scheme in FIG. 4, BS1 can determine the information of the resource in which the two sensing tasks interfere with each other by instructing the UE to perform sensing measurement. Thus, BS1 can adjust the resource of the sensing task performed by BS1 with the UE according to the determined resource in which there is interference, or instruct BS2 to adjust the resource of the sensing task with the sensing target, so as to make either sensing task avoid using the resource in which there is interference.

[0315] In the example of FIG. 4, the BS 1 performing the measurement and the resource adjustment for the subsequent communication task and / or the sensing task is taken as an example. In other embodiments, the functions of the BS 1 in the above example can also be performed by the BS 2 performing the sensing communication.

[0316] For example, referring to FIG. 5, an interaction diagram of another communication method provided by the embodiments of the present application is shown. In this example, the BS 2 can instruct the UE to perform the sensing measurement. This scheme can be applied to the case where the BS 1 does not have the sensing measurement capability. In other implementations, since the BS 2 as a sensing device necessarily has the capability of sensing measurement (i.e., sending the sensing measurement signal), this scheme can also be applied to the case where the BS 1 has the sensing measurement capability.

[0317] In some implementations, the BS 1 can perform the communication task with the UE before performing the scheme as shown in FIG. 5. In addition, the BS 2 can perform the sensing task with the sensing target (or the UE) near the UE. The BS 1 can attempt to improve the signal quality of the communication task by itself after detecting the decline of the signal quality of the communication task. In the case where the BS 1 cannot improve the signal quality of the communication task by itself, the BS 1 can send the corresponding indication information to the BS 2. The BS 2 can trigger the sensing measurement and the resource adjustment as shown in FIG. 5 according to the indication information sent by the BS 1.

[0318] Similar to the description in FIG. 4, in this example of FIG. 5, the UE can perform the first task (such as the communication task) with the BS 1. The UE can also receive the first signal. The first signal can correspond to the first sensing task. The first signal can include the signal directly sent by the BS 2 and / or the signal reflected by the sensing target (such as the user) when the BS 2 performs the first sensing task with the UE or the sensing target near the UE.

[0319] As shown in FIG. 5, the scheme can include:

[0320] S501, the BS 2 sends a UE sensing capability request to the BS 1, and the BS 1 sends a UE sensing capability request to the UE.

[0321] For example, the specific configuration of the UE sensing capability request can refer to S402 in FIG. 4, and details are not repeated here.

[0322] In other implementations of the present application, the BS 2 can also send the UE sensing capability request to the UE directly through the data transmission link between the BS 2 and the UE.

[0323] In this example, the BS 2 can send the sensing capability request to the UE through the communication link between the BS 1 and the UE.

[0324] S502, the UE sends UE awareness capability information to BS1, and BS1 sends the UE awareness capability information to BS2.

[0325] For example, the specific configuration of the UE awareness capability information can refer to S403 in FIG. 4, and details are not described herein again.

[0326] In this example, BS2 can obtain the UE awareness capability information sent by the UE through the communication link between BS1 and the UE.

[0327] In some other implementations of the present application, BS2 can also obtain the UE awareness capability information sent by the UE directly through the data transmission link between BS2 and the UE.

[0328] S503, BS2 sends awareness measurement parameter indication information to BS1, and BS1 sends the awareness measurement parameter indication information to the UE.

[0329] For example, the specific configuration of the awareness measurement parameter indication information can refer to S404 in FIG. 4, and details are not described herein again.

[0330] In this example, BS2 can send the awareness measurement parameter indication information to the UE through the communication link between BS1 and the UE.

[0331] In some other implementations of the present application, BS2 can also send the awareness measurement parameter indication information to the UE directly through the data transmission link between BS2 and the UE.

[0332] S504, the UE sends confirmation information to BS1, and BS1 sends the confirmation information to BS2.

[0333] For example, the specific configuration of the confirmation information can refer to S405 in FIG. 4, and details are not described herein again.

[0334] In this example, BS2 can obtain the confirmation information sent by the UE through the communication link between BS1 and the UE.

[0335] In some other implementations of the present application, BS2 can also obtain the confirmation information sent by the UE directly through the data transmission link between BS2 and the UE.

[0336] S505, BS2 sends an awareness measurement signal to the UE.

[0337] The awareness measurement signal can be used for the UE to perform awareness measurement. Unlike S406 shown in FIG. 4, BS1 sends the awareness measurement signal to the UE through the communication link; in this example, BS2 can send the awareness measurement signal to the UE through the awareness link.

[0338] In some implementations, the sensing measurement signal can be different from the sensing signal being used for the ongoing sensing task.

[0339] In some other implementations, the sensing measurement signal can partially or totally reuse the resource of the sensing signal being used for the ongoing sensing task.

[0340] S506, the UE sends the sensing measurement report to the BS1, and the BS1 sends the sensing measurement report to the BS2.

[0341] For example, the specific configuration of the sensing measurement report can refer to S407 in FIG. 4, and will not be described in detail.

[0342] In this example, the BS2 can obtain the UE sensing measurement report sent by the UE through the communication link between the BS1 and the UE.

[0343] In some other implementations of the present application, the BS2 can also directly obtain the UE sensing measurement report sent by the UE through the data transmission link between the BS2 and the UE.

[0344] S507, the BS2 sends the adjusted communication task resource to the BS1, and the BS1 sends the adjusted communication task resource to the UE.

[0345] S508, the BS2 performs the sensing task using the adjusted sensing task resource.

[0346] For example, the specific implementation of the BS2 adjusting the communication task resource and the sensing task resource in S507-S508 can refer to the above description, and will not be described in detail.

[0347] It can be understood that, similar to the scheme example in FIG. 4, when the first task performed by the BS1 and the UE includes the sensing task, the BS2 can effectively cooperate with the BS1 and the UE to perform the sensing measurement and determine the resource with interference in the two sensing tasks through the scheme implementation as shown in FIG. 5, and then adjust the resource of any sensing task to avoid the interference between the sensing tasks.

[0348] Therefore, in combination with the scheme description of FIG. 4 and FIG. 5, in the embodiments of the present application, the execution subject of obtaining the UE sensing capability, cooperating with the UE to perform the sensing measurement, and adjusting the task resource can be the BS1 performing the communication task or the BS2 performing the sensing task. In specific implementations, the above steps can also be partially executed by the BS1 and the BS2, so that the BS1 and the BS2 cooperate with each other to avoid the interference between the communication task and the sensing task.

[0349] In the foregoing description of the solutions provided by the embodiments of the present application, the BS 2 is taken as an example to perform the sensing task. In some other embodiments of the present application, the sensing task can also be initiated by other devices. For example, the sensing task can be initiated by the UE 2.

[0350] In this way, the UE 2 can perform the sensing measurement on the sensing target according to the configured sensing resource. In combination with the foregoing description, the sensing target can include a sensed active device (such as another terminal device), a sensed passive object (such as a user), and the like.

[0351] The sensing resource used by the UE 2 can be configured to the UE 2 by a network device of a cell in which the UE 2 is located.

[0352] In some embodiments, the UE 1 and the UE 2 are taken as an example to be located in a cell coverage range of a same base station (such as the BS 1). Referring to FIG. 6.

[0353] On one hand, the BS 1 can perform the communication task with the UE 1 through a communication link as shown in FIG. 6.

[0354] On the other hand, the UE 2 can perform the sensing task with the sensing target through a sensing link as shown in FIG. 6. In some implementations, the sensing resource used by the UE 2 to perform the sensing task can be configured to the UE 2 by the BS 1. In some other embodiments, the sensing resource used by the UE 2 to perform the sensing task can be configured to the UE 2 by other network devices.

[0355] In some examples, the UE 2 is taken as an example to perform the sensing task through the sensing resource configured by the BS 1. The sensing resource can include at least one of the following: a beam resource used for the sensing task, a time domain resource used for the sensing task, and a frequency domain resource used for the sensing task.

[0356] In the example as shown in FIG. 6, when the sensing target is relatively close to the UE 1, the sensing signal received by the sensing target is reflected and then received by the UE 1. In this way, the reflected sensing signal is interference signal for the UE 1, which can interfere with the communication task of the UE 1. Correspondingly, in the sensing task, the signal reflected by the sensing target to the UE 2 can include not only the reflection of the sensing signal by the sensing target, but also the signal of the communication task transmitted by the BS 1 and then reflected by the sensing target. Therefore, the communication task can also interfere with the sensing task. That is, the communication-sensing interference or the cross-link interference in the foregoing example.

[0357] The embodiments of the present application also provide a communication method, which can effectively reduce or avoid the cross-link interference in the scenario as shown in FIG. 6.

[0358] For example, referring to FIG. 7, an interaction flow diagram of another communication method provided by the embodiments of the present application is shown. In this example, UE2 performs the sensing task, and both UE2 and UE1 are within the coverage of the cell of BS1.

[0359] Similar to the description in FIG. 4 or FIG. 5, in the example of FIG. 7, UE1 can perform a first task (e.g., a communication task) with BS1. UE1 can also receive a first signal. The first signal can correspond to a first sensing task. The first signal can include a signal directly emitted by UE2 and / or a signal reflected by a sensing target (e.g., a user) near UE2 when UE2 performs the first sensing task with the sensing target.

[0360] As shown in FIG. 7, the method can include the following steps:

[0361] S701. BS1 sends a UE sensing capability request to UE1.

[0362] S702. UE1 sends UE sensing capability information to BS1.

[0363] For example, the execution process of S701-S702 can refer to S402-S403 in FIG. 4, and will not be described in detail.

[0364] It should be noted that in this example, UE2 performs the sensing task. BS1 can configure sensing resources for UE2 to perform the sensing task before UE2 performs the sensing task.

[0365] In some embodiments, the sensing resources can include at least one of the following: beam resources for the sensing task, time domain resources for the sensing task, and frequency domain resources for the sensing task.

[0366] For example, BS1 can configure UE2 to perform the sensing task in time period 1 and time period 2 (corresponding to time domain resources). BS1 can configure UE2 to perform the sensing task using frequency band 1 and frequency band 2 (corresponding to frequency domain resources). BS1 can configure UE2 to perform the sensing task using beam 1 and beam 2 (corresponding to beam resources).

[0367] Correspondingly, UE2 can perform sensing on the sensing target using the configured sensing resources.

[0368] It can be understood that when the configured sensing resources of UE2 include multiple items, UE2 can use a part of the resources at the same time to perform the sensing task.

[0369] For example, UE2 can use frequency band 1 and beam 1 to perform the sensing task in time period 1. For another example, UE2 can use frequency band 2 and beam 2 to perform the sensing task in time period 2.

[0370] It should be noted that, without specific configuration, the combination of the time domain resource, the frequency domain resource and the beam resource can be determined by the UE 2 itself or configured by the BS 1.

[0371] S703. The BS 1 sends the sensing measurement parameter indication information to the UE 1.

[0372] For example, the S703 can be implemented by referring to the S404 in the foregoing FIG. 4.

[0373] In some implementations of the embodiments of the present application, the BS 1 can determine the sensing measurement parameter indicated in the sensing measurement parameter indication information according to the resource information currently used by the UE 2.

[0374] For example, the sensing measurement parameter can at least include: a measurement type corresponding to the resource used by the UE 2, a sensing measurement quantity, a sensing measurement interval, etc.

[0375] In this example, the BS 1 can obtain the resource information currently used by the UE 2 before performing the S703.

[0376] In some implementations, the UE 2 can periodically feed back the currently used resource information to the BS 1. In other implementations, the BS 1 can send relevant request information to the UE 2 before performing the S703, for requesting the UE 2 to feed back the currently used resource. Correspondingly, the UE 2 can feed back the currently used resource information to the BS 1 according to the received request information.

[0377] In this way, the BS 1 sends the sensing measurement parameter indication information to the UE 1, which can indicate the UE 1 to perform the measurement of the interference at least for the sensing resource used by the UE 2.

[0378] In other implementations of the embodiments of the present application, the BS 1 can configure the sensing measurement parameter indication information according to the current actual network situation. The specific implementation is as described in the S404 and the related description.

[0379] S704. The UE 1 sends the confirmation information to the BS 1.

[0380] S705. The BS 1 sends the sensing measurement signal to the UE 1. In other implementations, the sensing measurement signal can be sent by the UE 2 performing the sensing task. For example, the BS 1 can instruct the UE 2 to send the sensing measurement signal corresponding to the sensing measurement parameter.

[0381] S706. The UE 1 sends the sensing measurement report to the BS 1.

[0382] For example, the processing mechanism of the S704-S706 can be implemented by referring to the S405-S407 in the FIG. 4.

[0383] Therefore, UE1 can perform sensing communication interference measurement under the configuration of BS1, thereby confirming information about the resources where interference exists.

[0384] In some embodiments, BS1 can determine time-domain information where interference exists. For example, the time-domain information where interference exists includes: time period 1.

[0385] In other embodiments, BS1 can determine frequency domain information indicating the presence of interference. For example, the frequency domain information indicating interference may include frequency band 1.

[0386] In other embodiments, BS1 can determine the beam information where interference exists. For example, the beam information where interference exists includes: beam 1.

[0387] Based on the information about the interfering resources, BS1 can adjust the resources used for communication tasks or sensing tasks. This prevents the communication or sensing tasks from using the interfering resources, thereby avoiding cross-link interference between the two tasks.

[0388] For example, taking the adjustment of resources for the communication task by BS1 as an example, the solution may further include S707. Correspondingly, taking the adjustment of resources for the sensing task by BS1 as an example, the solution may further include S708.

[0389] S707 and BS1 send the adjusted communication task resources to UE1.

[0390] For example, BS1 may no longer use resources that cause interference to perform communication tasks with UE1.

[0391] For example, if the resource causing interference includes time period 1, then BS1 will no longer use time period 1 to communicate with UE1, but will instead use other time-domain resources. Correspondingly, BS1 can send the adjusted time-domain resources for the communication task (excluding time period 1) to UE1 so that UE1 can communicate with BS1 using those time-domain resources.

[0392] For example, if the resources causing interference include frequency band 1, then BS1 will no longer use frequency band 1 to communicate with UE1. Instead, it will use other frequency domain resources to communicate with UE1. Correspondingly, BS1 can send the adjusted frequency domain resources for the communication task (such as excluding frequency band 1) to UE1 so that UE1 can communicate with BS1 using those frequency domain resources.

[0393] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0394] S708, BS 1 sends the adjusted sensing task resource to UE 2.

[0395] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0396] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0397] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0398] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0399] For example, the interfering resource includes time period 1. Then, the adjusted sensing task resource can not include time period 1. After BS 1 sends the adjusted sensing task resource to UE 2, UE 2 can no longer use time period 1 for the sensing task.

[0400] It can be understood that, similar to the scheme examples in FIG. 4 and FIG. 5, in the scheme implementation as shown in FIG. 7, when the first task between BS 1 and UE 1 includes the sensing task, then through the similar scheme implementation as shown in FIG. 7, UE 2 can effectively cooperate with BS 1 and UE 1 to perform the sensing measurement, and determine the interfering resource in the two sensing tasks. Further, the resource of any one sensing task is adjusted to avoid the interference between the sensing tasks.

[0401] The above description of the scheme provided by the embodiments of the present application is made from the perspective of a UE and a base station (e.g., BS1). As an example, the following provides a constituent example of a hardware structure of a terminal device (i.e., UE).

In some embodiments, the antenna 1 and the mobile communication module of the terminal device are coupled, and the antenna 2 and the wireless communication module are coupled, so that the terminal device can communicate with the network side device and other terminal devices through the wireless communication technology.

[0406] In addition, on the above-mentioned components, an operating system runs. For example The operating system developed by the company The operating system developed by the company The operating system developed by the company The open source operating system developed by the company The operating system developed by the company The operating system developed by the company

[0407] The operating system of the terminal device can adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiments of the present application exemplarily illustrate the software and hardware structure of the terminal device taking the layered architecture of the system as an example. It should be noted that the embodiments of the present application take the system as an example for illustration, but the basic principles are also applicable to terminal devices based on or and the like operating system.

[0408] Exemplarily, referring to FIG. 8, a software structure block diagram of a terminal device provided by the embodiments of the present application is shown. The software structure adopts a layered architecture, which divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. Taking the system, system running on the AP as an example, in some embodiments, the Android system is divided into five layers, from top to bottom, the application layer, the application framework layer (Framework), the Android runtime and system library, the hardware abstraction layer (HAL), and the system kernel layer (Kernel).

For example, the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, etc. The phone manager is used to provide the call function of the terminal device, such as the management of the call state (including call connection, call hang-up, etc.), and the phone manager is represented by telephony in FIG. 8.

[0415] In some implementations of the present application, a modem can have a sensing measurement capability. For example, the modem can be configured to transmit a sensing signal of a sensing task corresponding type. The sensing signal of the sensing task corresponding type can include a radar signal, etc. In this way, the communication device configured with the modem also has a sensing measurement capability. For example, when the BS1 is configured with the modem having a sensing measurement capability, the BS1 can perform sensing measurement and resource adjustment according to the implementation of the schemes shown in FIG. 4 or FIG. 7.

[0416] In some other implementations, the sensing measurement capability of the communication device can also be implemented by a separate or integrated sensing measurement capable device configured in the device. For example, a transceiver having a sensing measurement capability can be configured in the communication device. In this way, when the BS1 is configured with the transceiver having a sensing measurement capability, the BS1 can perform sensing measurement and resource adjustment according to the implementation of the schemes shown in FIG. 4 or FIG. 7.

[0420] It can be understood that the composition of the communication device 900 shown in FIG. 9 is only an example and is not limited to the communication device.
