Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and a communication device. Background Technology

[0002] With the development of communication technology, sensing and communication tasks of terminal devices are coordinated to improve the communication experience of terminal devices.

[0003] When the frequency domain and time domain resources of sensing and communication tasks overlap, the sensing and communication tasks may interfere with each other on the terminal device side, resulting in a decrease in the quality of both sensing and communication tasks. Summary of the Invention

[0004] This application provides a communication method and a communication device that can reasonably adjust the resource configuration of communication tasks or sensing tasks according to the time domain and / or beam characteristics of communication sensing interference, thereby avoiding link cross-interference between sensing tasks and communication tasks.

[0005] To achieve the above technical objectives, this application adopts the following technical solution:

[0006] A first aspect provides a communication method applied to a first network device, the first network device performing a first task with the first terminal device, the first task including a communication task and / or a sensing task. The first terminal device also receives a first signal sent by a second device, the first signal corresponding to the first sensing task. The method includes: sending a first message including sensing measurement parameters, the sensing measurement parameters being determined based on the first task and / or configured resources of the first sensing task; sending a sensing measurement signal for the first terminal device to perform a measurement based on the sensing measurement parameters; receiving a second message including the first measurement report. The first measurement report is generated by the first terminal device when the result of the measurement satisfies a condition corresponding to at least one threshold indicated by the sensing measurement parameters; and adjusting the resources for performing the first task with the first terminal device according to the second message, or instructing the second device to adjust the resources for the sensing task corresponding to sending the first signal.

[0007] In this implementation, the first network device can determine the resources experiencing interference based on the measurement report obtained by the first terminal device. For example, it can determine the interfering beam resources, frequency domain resources, and time domain resources. It is understood that the interfering resources can be included in the communication resources of a configured communication task or the sensing resources of a configured sensing task. Thus, the first network device can adjust the resources of the communication task or sensing task based on the known interfering resources, so that the communication task or sensing task can avoid using the interfering resource. It is understood that as long as one of the communication task or sensing task no longer uses the interfering resource, interference between the two tasks arising from that resource can be avoided.

[0008] In this example, the first task can also be a sensing task. In this example, the first network device can adjust the resources of the sensing task performed by the first network device or the sensing task performed by the second device based on the first message reported by the first terminal device regarding the existence of interfering resources, thereby avoiding mutual interference between the two tasks on interfering resources.

[0009] In this way, regardless of whether the primary task is a communication task or a sensing task, it can be achieved through the above scheme, avoiding interference from the primary signal to the primary task and improving the signal quality of the primary task.

[0010] Based on the solution provided in the first aspect, since the sensing measurement parameters are determined according to the first task and / or the configured resources of the first sensing task, the resources that the first network device instructs the first terminal device to perform sensing measurements can be included in the configured communication resources and / or sensing tasks. This allows the first terminal device to perform sensing measurements more specifically. For example, the first terminal device can perform sensing measurements on each resource in the configured communication resources to determine whether interfering resources exist in the configured communication resources. Similarly, the first terminal device can perform sensing measurements on each resource in the configured sensing resources to determine whether interfering resources exist in the configured sensing resources.

[0011] Optionally, the first network device is a first base station. The second device is a second terminal device or a second base station.

[0012] Taking the first task as a communication task as an example, the first base station can be a communication base station. Taking the first task as a sensing task as an example, the first base station can be a sensing base station or a sensing-communication integrated base station.

[0013] Taking a self-initiated and self-received sensing task as an example, the second base station can be a sensing base station. Taking a collaborative sensing task where the first sensing task is self-initiated and self-received as an example, the second device can be a second terminal device with sensing and measurement capabilities.

[0014] It is understandable that, when the second device is a base station, the first base station can send information about the adjusted sensing resources or unusable sensing resources to the second base station so that the second base station can adjust the sensing resources for the sensing task itself.

[0015] Correspondingly, when the second device is a terminal device, the sensing resources for the second device to perform sensing tasks can be configured by the first network device. In this way, the first network device can send information about the adjusted sensing resources, or the unusable sensing resources, to the second terminal device, so that the second terminal device can perform sensing tasks according to the newly configured resources of the first network device.

[0017] It is understandable that the first signal could be a signal emitted by the second device when performing a sensing task on the first terminal device. In this case, the signal could be directly sent from the second device to the first terminal device. Alternatively, the first signal could be a sensing signal emitted by the second device to a sensing target near the first terminal device. In this case, the signal could be a signal received by the first terminal device after being reflected by the sensing target.

Alternatively, the second device is a second terminal device. Adjusting the resources for transmitting the sensing task corresponding to the first signal includes: sending adjusted time-domain resources of the sensing task to the second terminal device, wherein the time-domain resources of the adjusted sensing task do not include the first time period. Alternatively, sending unavailable time-domain resources of the sensing task to the second terminal device, wherein the time-domain resources of the unavailable sensing task include the first time period.

[0073] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0074] With the development of wireless communication technology, the sixth generation mobile communication technology (6G) has begun to receive widespread attention.

[0075] Compared to 5G, 6G focuses on communication services and basic location services.

[0076] 6G will integrate sensing and communication capabilities to build an Integrated Sensing and Communication (ISAC) system, enabling modeling of the spatial structure, mobility, and surrounding environment of both connected and unconnected devices. Typical sensing scenarios may include ranging and velocity measurement, high-precision positioning and tracking, imaging, target detection, and pattern recognition. The objects sensed in these scenarios may include users.

[0077] In the ISAC system, sensing and communication functions mutually reinforce each other. On the one hand, the communication system assists the sensing function, such as extracting sensing information from communication signals while sensing, thereby enhancing the sensing function. On the other hand, the sensing system assists the communication function, such as using the results of sensing scans to assist in beam management.

[0078] In practical system deployment, the sensing and communication systems can be integrated in stages. The first stage is service coexistence, where the communication and sensing systems use independent hardware and are considered interference to each other. The second stage is capability cooperation, where the communication and sensing systems use independent hardware but share information. The third stage is integrated communication and sensing design (referred to as integrated communication and sensing), where the communication and sensing systems are integrated into one system, sharing hardware, resources, integrated air interface, and integrated waveform.

[0079] Taking the first and second phases of deployment as examples, this involves configuring corresponding base stations (BS) for the communication system and the sensing system respectively. For instance, the base station used for communication tasks may be BS1, and the base station used for sensing tasks may be BS2. BS1 and BS2 are different.

[0080] Correspondingly, in the case of the third phase of deployment, BS1 can share some or all of its hardware with BS2. For example, BS1 and BS2 can be the same base station.

[0081] Take a communication task scenario as an example.

[0082] In this example, BS1 can transmit data or commands to the user (User Equipment, UE) via a communication link, thereby achieving the communication task. It is understood that in some implementations, BS1 may be a communication base station capable only of communication tasks. In other implementations, BS1 may be a base station capable of both communication and sensing tasks, such as a sensing-integrated base station. Therefore, BS1 can achieve both communication tasks with the UE and sensing tasks with the UE as the sensing target by sending sensing-integrated signals to the UE.

[0083] It should be noted that in different implementations, the sensing target can be an active device or a passive target. Active devices can include terminal devices, user equipment (UE), etc. Passive targets can include users, vehicles, etc.

[0084] In some embodiments, BS1 can perform communication tasks with UE through any one or more of the following waveforms: Orthogonal Frequency Division Multiplexing (OFDM) waveform; Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform; Discrete Fourier Transform-Spread OFDM (DFT-S-OFDM) waveform, etc.

[0085] In this embodiment of the application, the communication task can be performed based on any of the following communication protocols:

[0086] The cellular communication protocols corresponding to 4G networks (Long Term Evolution-Advanced, LTE-A), 5G networks (New Radio, NR), and 6G networks (Wi-Fi, Bluetooth, Zigbee, etc.) and short-range communication protocols (Wi-Fi, Bluetooth, Zigbee, etc.).

[0087] Take the perception task scenario as an example.

[0088] In this example, BS2 can transmit sensing beams in different directions using methods such as beam scanning, and these beams can carry sensing signals. For example, BS2 can transmit a sensing beam in the direction of a sensing target (such as a user) via a sensing link. The sensing signal in the beam can be received by BS2 after being reflected by the user. In this way, BS2 can perceive the user based on the transmitted sensing signal and the received reflected sensing signal. For example, it can determine the user's location and identify the user.

[0089] In some implementations, the sensing task can be a spontaneous and self-receiving sensing task. For example, BS2 can send sensing signals to the sensing target (i.e., spontaneously). BS2 can receive sensing signals reflected from the sensing target (i.e., self-receiving) and realize the sensing target based on the received sensing signals (or the received sensing signals and the sent sensing signals).

[0090] In other implementations, the sensing task can be a self-initiated and other-received sensing task. For example, BS2 can collaborate with other devices (such as UE1, BS2, etc.) to achieve sensing of a target. In this example, BS2 can send a sensing signal to the target (i.e., self-initiated). Other devices can receive the sensing signal reflected by the target (i.e., other-received). In this way, other devices or BS2 can obtain the reflected sensing signal through signal synchronization, thereby achieving sensing of the target. This self-initiated and other-received sensing task can also be called a collaborative sensing task.

[0091] In different implementations, the waveforms used for sensing tasks can differ. In some embodiments, BS2 can perform sensing tasks using 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.

[0092] It should be noted that in some cases, the sensing signals used for sensing tasks and the communication signals used for communication tasks can be different. For example, the beam type, frequency range, and / or time domain range of the sensing and communication signals can differ. Take the difference in beam type as an example: sensing signals can be transmitted using radar beams, while communication signals generally do not use radar beams.

[0093] Thus, in a sensing system, devices performing sensing tasks (referred to as sensing devices, such as BS2) can be configured to have sensing (or sensing measurement) capabilities. In some implementations, the sensing device may include hardware devices (such as transmitters) capable of sensing to support different sensing signals. In other implementations, the modem in the sensing device may be configured to have sensing capabilities to support different sensing signals.

[0094] Correspondingly, in a communication system, the device performing the communication task (referred to as the communication device, such as BS1) can be configured to have communication (or communication measurement) capabilities. In some implementations, the communication device can include hardware devices (such as a transmitter) capable of communication to support different communication signals. In other implementations, the modem in the communication device can be configured to have communication capabilities to support different communication signals.

[0095] It is understandable that, in the case of separate deployment of sensing and communication devices, the communication devices may only support communication measurements and not sensing measurements. Alternatively, the communication devices may support both communication and sensing measurements.

[0096] In the case of a combined deployment of sensing and communication devices (such as a sensor-integrated system), the communication devices can support both communication and sensing measurements.

[0097] In some cases, the sensing target and the device performing the communication task (such as a terminal device) are relatively close. For example, the sensing target may be a user, and the device performing the communication task may be the user's terminal device. This situation arises when the user is holding or carrying the terminal device.

[0098] Taking the example of communication and sensing tasks using the same time-domain and frequency-domain resource configurations and uplink / downlink configurations, the terminal device performs communication tasks and sensing tasks targeting the sensing target (user) simultaneously, and the frequency-domain resource configurations and uplink / downlink configurations of the communication link and sensing link are identical. Thus, sensing signals reflected by the user and / or sensing signals transmitted by BS2 will also be received by the terminal device. This results in cross-link interference between the sensing signals and the communication signals of the communication tasks.

[0099] For example, such as Figure 1 As shown, for the terminal device, during communication with BS1, it can receive the communication signal of the communication task through the communication link. In addition, the terminal device can also receive the sensing signal reflected by the user. Because the time domain and frequency domain configurations are the same, the communication signal and the sensing signal will interfere with each other, reducing the communication quality of the communication task.

[0100] For similar reasons, the transmission of data in communication tasks may also lead to a decrease in the accuracy of perception tasks.

[0101] It should be noted that the above example uses a user as the sensing target. In other embodiments, the sensing target may also include other objects. For example, objects similar to a user that do not actively communicate, such as houses or cars. Another example is terminal devices that can communicate with network devices, such as other UEs. When the sensing target is another UE (such as UE2), BS2 can sense UE2 by transmitting sensing signals to UE2. In this case, the UE performing the communication task (such as UE1) will also experience interference with its communication task due to receiving the sensing signals sent by BS2 to UE2.

[0102] It is understandable that the UE can perform communication tasks in various ways in the above examples. For example, the UE can perform communication tasks by directly interacting with BS1. Alternatively, the UE can perform communication tasks with BS1 by executing a communication awareness task. These various implementations of performing communication tasks can be simply referred to as the UE performing the first task with BS1.

[0103] The above description uses the example of a UE receiving a sensing signal (such as a sensing signal, also referred to as a first signal) while performing a communication task. In other implementations, when the UE performs a sensing task (such as directly receiving a sensing signal sent by a sensing device, or performing a cooperative sensing task), interference between the two signals may occur due to receiving sensing signals from other sensing tasks. In this application, the task performed by the UE that is interfered with by other sensing tasks can be referred to as the first task. This first task may include a communication task, a cooperative sensing task, and / or a sensory integration task.

[0104] In the following explanation, the first task is the communication task as an example. The mutual interference between the communication task and the sensing task can be called communication-sensing interference.

[0105] Based on this, the technical solution provided in this application embodiment can utilize the UE's sensing capabilities to coordinate the configuration of BS1 and BS2 resources, thereby avoiding cross-interference between sensing and communication links.

[0106] The solutions provided in this application can be applied to scenarios where communication and sensing tasks coexist. In some embodiments, the hardware corresponding to the communication task (such as a base station, BS1, etc.) and the hardware corresponding to the communication task (such as BS2, etc.) may be different, corresponding to the configuration of the first or second stage described above. In other embodiments, BS1 and BS2 may also be integrated in the same base station, corresponding to the configuration of the third stage described above. This application does not impose any limitations on this.

[0107] Taking BS1 as a communication device for communication tasks and BS2 as a sensing device for sensing tasks as an example.

[0108] refer to Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application. In this example, the solution is applied to a first base station.

[0109] In some embodiments, the first base station may correspond to BS1 as described above. Correspondingly, the second base station may correspond to BS2 as described above. In other embodiments, the first base station may also correspond to BS2 used for performing sensing tasks, in which case the second base station may correspond to BS1. This application does not impose any limitations on these embodiments.

[0110] It is understood that in some embodiments, taking BS1 as the first base station and BS2 as the second base station as an example, BS1 can perform communication tasks with the UE. BS2 can perform sensing tasks with the UE. The resources used by the communication tasks and the sensing tasks may at least partially overlap. For example, the frequency domain resources and time domain resources of the currently performing communication task may be the same as the frequency domain resources and time domain resources of the currently performing sensing task. That is, the communication task and the sensing task are currently performing simultaneously, and the communication task and the sensing task use the same frequency.

[0111] In this example, BS1 can perform communication tasks with the UE. If the communication quality of a task deteriorates, BS1 can attempt to improve it. For example, BS1 can try adjusting the cell, beam, and frequency band used in the communication task to improve its quality.

[0112] If BS1 is unable to improve the quality of communication tasks through existing solutions, it may indicate that the current decline in communication task quality is caused by interference from other tasks (such as sensing tasks).

[0113] Therefore, BS1 can perform the following: Figure 2 The proposed solution avoids interference from the perception task on the communication task, thereby effectively improving the communication quality of the communication task.

[0114] It should be noted that the first base station can perform communication tasks with the UE. In this... Figure 2 During the execution of the illustrated process, the communication between the first base station and the UE can be maintained without interruption. Correspondingly, in this... Figure 2 During the execution of the process shown, the sensing device (such as BS2) can continue to perform the sensing task with the sensing target, or it can temporarily suspend the sensing task.

[0115] like Figure 2 As shown, the solution may include:

[0116] S201, The first base station acquires the UE's perception capability.

[0117] For example, the first base station can obtain the UE's sensing capability through signaling interaction with the UE.

[0118] In some embodiments, the sensing capability may include at least one of the following:

[0119] Sensing waveform; frequency domain bandwidth; time domain duration; time domain interval; guard interval; subcarrier interval.

[0120] Specifically, in some implementations, sensing capabilities may include sensing waveforms, time-domain duration, and time-domain intervals. In other implementations, sensing capabilities may include sensing waveforms, frequency-domain bandwidth, time-domain duration, time-domain intervals, guard intervals, and subcarrier intervals.

[0121] The sensing waveform is used to indicate waveform characteristics during the sensing task process. This sensing waveform can include any 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), or pulse signals.

[0122] Frequency domain bandwidth and time domain duration can be used to indicate the relevant characteristics corresponding to the sensed waveform. For example, taking a sensed waveform that includes a pulse signal as an example, 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.

[0123] As one possible implementation, the following provides a scheme for a first base station to acquire the UE's sensing capabilities. This scheme may include steps a1 and a2.

[0124] Step a1: The first base station sends a sensing capability request to the UE.

[0125] For example, in some embodiments, BS1 may send the UE Sensing Capability Request via Radio Resource Control (RRC) signaling.

[0126] For example, take the first base station as BS1.

[0127] In some implementations, BS1 can send awareness capability requests to all UEs within the BS1 cell coverage area via RRC signaling.

[0128] In other implementations, BS1 can send a perception capability request to the UE via broadcast.

[0129] In this application, the first base station may send a third message, which may include the sensing capability request.

[0130] Step a2: The UE sends sensing capability information to the first base station.

[0131] For example, the sensing capability information may include UE sensing capability information.

[0132] In some embodiments, taking UE support for a sensing task as an example, the UE can respond to a sensing capability request by feeding back its sensing capability information to BS1. This sensing capability information may include the UE's corresponding sensing capabilities. As described above, the sensing capabilities may include one or more of the following information during the UE's execution of the sensing task: sensing waveform, frequency domain bandwidth, time domain duration, time domain interval, guard interval, and subcarrier interval.

[0133] In other embodiments, taking the example of the UE not supporting the sensing task, the UE may refuse to receive the sensing capability request, or the UE may not respond after receiving the sensing capability request, or the UE may send a message to the first base station that it does not support the sensing capability.

[0134] The following explanation uses UE support for sensing tasks as an example.

[0135] Therefore, through steps a1 to a2, the first base station can know which UEs support the sensing task among those currently communicating with the first base station, as well as the sensing capabilities of each UE that supports the sensing task.

[0136] In this application, the first base station can send a fourth message, which may include the sensing capability information.

[0137] S202, The first base station configures the sensing measurement parameters to the UE.

[0138] In this application, the first base station can instruct the UE to perform sensing measurements. Through sensing measurements, the UE can determine the resources where interference exists from the currently configured resources for communication tasks (hereinafter referred to as communication resources) and / or resources for sensing tasks (hereinafter referred to as sensing resources).

[0139] It should be noted that, in the embodiments of this application, the resources of the task (such as sensing resources, communication resources, etc.) may include resources of multiple dimensions. For example, the resources of the task may include beam resources, and / or frequency domain resources, and / or time domain resources, etc.

[0140] The sensing measurement can be performed under the instruction of the first base station.

[0141] For example, in some embodiments, the first base station can determine sensing measurement parameters based on the currently configured communication resources. For instance, the sensing measurement parameters can be used to indicate whether or not some of the communication resources are to be measured.

[0142] In this way, by configuring sensing measurement parameters to the UE, the UE can measure the configured communication resources accordingly, thereby determining which of the configured communication resources are interfering.

[0143] In other embodiments, the first base station may determine sensing measurement parameters based on currently configured sensing resources. For example, the sensing measurement parameters may be used to indicate whether some or all of the sensing resources should be measured. In some implementations, the configured sensing resources may be obtained by the first base station from a second base station.

[0144] In this way, by configuring sensing measurement parameters to the UE, the UE can measure the configured sensing resources accordingly, thereby determining which of the configured sensing resources are interfering.

[0145] In other embodiments, the first base station may determine sensing measurement parameters based on the currently configured sensing resources and communication resources. For example, the sensing measurement parameters may be used to indicate that some or all of the sensing resources and / or some or all of the communication resources are to be measured.

[0146] In this way, by configuring sensing measurement parameters to the UE, the UE can measure the configured resources (such as sensing resources and / or at least a portion of communication resources) accordingly, thereby determining which of the configured resources are interfering.

[0147] In some embodiments, the sensing measurement parameters may include one or more thresholds. These one or more thresholds may correspond to threshold usage conditions, collectively constituting threshold conditions. The UE can determine whether to generate a corresponding measurement report based on the measurement results and the threshold conditions. This measurement report can be used to indicate that the resource corresponding to the currently measured sensing signal is subject to interference.

[0148] In different implementations, the threshold can be used when the first base station is configured as the UE, or it can be used when the UE and the first base station have negotiated in advance (e.g., as specified by a standard protocol).

[0149] As an example, let's take BS1 as the first base station. BS1 can configure sensing measurement parameters for each UE that supports the sensing task. These sensing measurement parameters can be used to instruct the UE to perform sensing task measurements. In some implementations, these sensing measurement parameters can be included in the first message.

[0150] In some embodiments, the sensing measurement parameters may include at least one of the following: the type of sensing measurement signal, the sensing measurement quantity, the sensing measurement interval, the sensing measurement threshold, and the number of sensing interferences.

[0151] The following will explain each point separately.

[0152] The type of sensing measurement signal is used to indicate the object being measured during the sensing measurement process of the UE.

[0153] In some implementations, the type of the sensing measurement signal may include a measurement reference signal during the communication task. For example, the type of sensing measurement signal may include one or more of the following: Synchronization Signature Block (SSB), Channel State Information Reference Sign (CSI-RS), Demodulation Reference Sign (DMRS), Signaling Reference Sign (SRS), etc.

[0154] In other implementations, the type of the sensing measurement signal may include a reference signal during the sensing task. For example, the type of sensing measurement signal may include one or more of the following: a reference signal based on the sensing waveform, i.e., OFDM, FMCW, OTFS, SC-FDMA, or a pulse signal. It may also be a sensing integrated signal, such as a sensing integrated signal based on OFDM and / or OTFS.

[0155] Sensing measurement parameters are used to indicate the specific parameters that the UE needs to measure after receiving the type of sensing measurement signal.

[0156] In some implementations, the sensing measurement quantities may include at least one of the following: sensing signal strength, sensing signal-to-interference ratio, sensing interference time offset, sensing interference duration, sensing interference period, sensing interference duty cycle, sensing interference quantity, block error rate, etc. Among these, sensing signal strength indicates the signal strength of the received sensing signal; sensing signal-to-interference ratio indicates the ratio of the sensing signal to the noise floor and other interferences.

[0157] The sensing measurement interval indicates the start and end times of the sensing measurement. In some embodiments, there is no uplink or downlink transmission during the sensing measurement start and end times. That is, during the execution of the sensing measurement, the UE can temporarily suspend communication tasks according to the sensing measurement interval, thereby ensuring measurement accuracy.

[0158] Taking a pulse signal as an example, the sensing waveform can be used. The sensing measurement interval can include information such as the duration of the sensing measurement and the repetition period.

[0159] A sensing measurement threshold is used to indicate a threshold related to sensing measurements. Exemplarily, in some embodiments, the sensing measurement threshold may include a threshold for initiating a measurement and / or a threshold for generating a sensing measurement report. This threshold may be a threshold specific to the amount of sensing measurement.

[0160] In different implementations, the threshold for generating a perception measurement report may include one or more. For example, consider a scenario where multiple thresholds are used to generate a perception measurement report. Different thresholds correspond to generating different measurement reports.

[0161] Taking the block error rate (BER) as an example, the sensing measurement threshold can include one or more thresholds corresponding to the BER.

[0162] In some embodiments, the configuration of the sensing measurement threshold can be related to parameters such as the waveform of the sensing task. For example, taking a pulse 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 between pulses. Correspondingly, the sensing measurement threshold may include the amplitude at which detection is enabled, the amplitude threshold for generating a measurement report, or other conditions.

[0163] The number of sensed interferences indicates the amount of sensed interference that may exist at the UE's current location. Taking the example of a single base station performing a maximum of one sensed task simultaneously, multiple base stations (such as multiple BS2s) may be simultaneously performing sensed tasks on the UE at its current location. Thus, the number of sensed interferences can be used to indicate the amount of sensed interference that may be present at the UE. Correspondingly, the UE can process the data acquired during the measurement process according to this number of sensed interferences, thereby separating one or more sensed interferences.

[0164] The following is an example of a scheme for configuring sensing measurement parameters from BS1 to UE. The process may include steps b1 to b2.

[0165] Step b1: BS1 sends sensing measurement parameter indication information to UE.

[0166] In some embodiments, the sensing measurement parameter indication information may be included in an RRC reconfiguration message sent by BS1 to the UE. This RRC reconfiguration message may include the aforementioned measurement configuration parameters. In some implementations, the measurement parameter indication information may be included in a first message.

[0167] Step b2: The UE sends an acknowledgment message to BS1.

[0168] In this example, we take the UE receiving the sensing measurement parameter indication information and obtaining the measurement configuration parameters therein as an example. The UE can send an acknowledgment message to BS1 so that BS1 can determine that the UE has received the measurement configuration parameters.

[0169] In some embodiments, this confirmation information may correspond to ACK information. After receiving the sensing measurement parameter indication information and obtaining the measurement configuration parameters therein, the UE sends an RRC Reconfiguration Complete message to BS1. This RRC Reconfiguration Complete message may include ACK information.

[0170] Correspondingly, in some other embodiments of this application, if the UE does not receive the sensing measurement parameter indication information within a preset time period, or if it fails to obtain the measurement configuration parameters normally after receiving the sensing measurement parameter indication information, it can send a message carrying NACK information to the BS1 so that the BS1 is aware of the sensing measurement configuration failure. Correspondingly, the BS1 can trigger sensing measurement reconfiguration, such as repeating the execution of S601.

[0171] Therefore, through this Figure 6 With the implementation of the scheme shown, BS1 can configure the sensing measurement parameters for the UE. Correspondingly, the UE can perform corresponding measurements based on the received sensing measurement parameters, thereby determining whether there is communication sensing interference between the sensing task and the communication sensing task, as well as information such as the time-domain characteristics of the communication sensing interference.

[0172] It should be noted that the configuration of the sensing measurement parameters is described in detail in the above example.

[0173] In other embodiments, BS1 may also configure the UE with interference beam information related to sensing tasks involving sensing interference beams, in addition to configuring sensing measurement parameters to the UE.

[0174] In this example, BS1 can communicate with BS2 via a wired or wireless link before executing S202, thereby obtaining the sensing task resource configuration parameters of BS2 that is performing the sensing task.

[0175] The resource configuration parameters for a sensing task may include at least one of the following: beam set, time slot configuration, start and end times, bandwidth, waveform parameters, etc., of the sensing task. For example, BS1 can obtain sensing waveform parameters, sensing beam information, sensing mode, and sensing transmit / receive time configuration information through communication with BS2.

[0176] The sensing waveform parameters include: sensing waveform, sensing signal duration, sensing time interval, bandwidth, etc. The sensing beam set includes: a set of sensing beam indicators and indices used for sensing tasks. The time slot configuration for sensing tasks includes: the time slots occupied by the sensing beams. Sensing beam information includes: sensing beam transmission period, the corresponding coverage area of ​​the sensing beam, the sensing beam index, and the sensing beam time-frequency resource configuration. Sensing modes include: self-transmitting and self-receiving, and self-transmitting and receiving. In self-transmitting and self-receiving sensing mode, the transmitting and receiving ends of the sensing task are the same device; in self-transmitting and receiving sensing mode, the transmitting and receiving ends of the sensing task are different. Sensing transmission and reception time configuration: the transmission and reception time configuration of the sensing base station, which is related to the beam direction, sensing area, and sensing task. Sensing tasks include: localization, tracking, imaging, pattern recognition, etc.

[0177] In this way, BS1 can determine the beam for the communication task covering the current location of the UE based on the cell where the UE is located. BS1 can also determine the UE's position relative to BS1 based on information such as the signal strength of the communication task. Based on the UE's current location, BS1 can determine the information of the sensing beam used by BS2 when performing a sensing task with the UE. This sensing beam is the interference beam for the communication task. For example, this interference beam could be the beam for the sensing task covering the current location of the UE.

[0178] In this example, BS1 can send information about the interfering beams of the sensing task (such as beam index) to the UE so that the UE can perform sensing measurements on the interfering beams.

[0179] S203. The UE performs perception measurement based on the perception measurement parameters and obtains the perception measurement results.

[0180] Understandably, the UE can continue its communication tasks while performing sensing measurements.

[0181] In some embodiments, the first base station may send sensing measurement signals during the sensing measurement process of the UE.

[0182] In some implementations, the beam resources and / or frequency domain resources and / or time domain resources used by the sensing measurement signal transmitted by the first base station can be the same as the sensing resources used for the sensing task. In this way, the UE can receive the sensing measurement signal and simultaneously receive the communication signal for the communication task. The UE can determine whether the current sensing measurement signal interferes with the communication signal based on the received sensing measurement signal and the communication signal.

[0183] For example, in some embodiments, the UE can perform sensing measurements for each beam in the sensing task based on sensing measurement parameters. When the result of the sensing measurement meets a threshold for generating a measurement report (such as a sensing measurement threshold), the UE can generate a corresponding sensing measurement report.

[0184] In other embodiments, BS1 is configured with information about interfering beams for the UE as an example. The UE can perform sensing measurements against the interfering beams based on sensing measurement parameters. When the results of the sensing measurements meet the threshold for generating a measurement report (such as the sensing measurement threshold), the UE can generate a corresponding sensing measurement report.

[0185] In this example, the UE can perform sensing measurements based on the type of sensing measurement signal, the sensing measurement quantity, and the sensing measurement interval in the sensing measurement parameters, and obtain the sensing measurement results. These sensing measurement results are, in other words, the results obtained by measuring the sensing measurement quantity for the type of sensing measurement signal.

[0186] As one possible implementation, the types of sensing and measurement signals include sensing reference signals, which include SSB, CSI-RS, DMRS, and pulse reference signals, and the sensing and measurement quantities include the sensing signal interference ratio.

[0187] During the execution of S203, the UE can separate the radar pulse from the type of the sensing measurement signal based on the UE's sensing capabilities and the prior information on sensing interference provided by the base station (such as BS1).

[0188] Specifically, the UE separates one or more pulse signals based on the pulse amplitude, pulse time interval, and pulse duration. The base station (such as BS1) can provide the UE with prior information about the duration and pulse time interval of the pulses sensed by the BS.

[0189] Taking continuous frequency modulation (FM) waves as an example, based on the UE's sensing capabilities and the prior information provided by the base station, the UE separates the sensing signal from the type of the sensing measurement signal. Specifically, the base station can provide the UE with prior information on the FM wave parameter configuration of the sensing base station. Based on this prior information, the UE calculates the spectral information of the corresponding FM wave. This spectral information includes: range spectrum, velocity spectrum, angle spectrum, range-velocity spectrum, and range-velocity-angle spectrum. Taking the range spectrum as an example, the UE can obtain the range spectrum information by performing a fast-time Fourier transform on the type of the sensing measurement signal after the analog-to-digital converter, and take the one or several components with the largest amplitude as the sensing signal, while the remaining components are considered interference. The interference ratio of the sensing signal is then calculated.

[0190] In some embodiments of this application, BS1 can send a sensing measurement signal to the UE one or more times during the UE measurement process. This allows the UE to perform measurements corresponding to the sensing measurement configuration through the sensing measurement signal.

[0191] S204. The UE generates a perception measurement report based on the perception measurement results.

[0192] For example, the UE can generate a corresponding perception measurement report based on the perception measurement results and the perception measurement threshold in the perception measurement parameters, provided that the perception measurement results meet the perception measurement threshold.

[0193] In this application, the perception measurement report may include at least one of the following:

[0194] The sensing measurement results, information on communication sensing interference, information on the sensing beam used in the sensing task, and information on the base station corresponding to the sensing task.

[0195] In some embodiments, the sensing measurement result includes the sensing signal-to-interference ratio (SMR). The sensing measurement threshold includes one or more thresholds corresponding to the SMR.

[0196] If the perceived signal interference ratio is greater than the corresponding perceived measurement threshold, the UE can generate a perceived measurement report. This perceived measurement report can be used to indicate the presence of communication perceived interference.

[0197] As described in S202, the perception measurement threshold can be configured by the first base station for the UE. The usage conditions corresponding to this perception measurement threshold (such as generating a report when the value is greater than the threshold, or generating a report when the value is less than the threshold) can be pre-negotiated or configured by the first base station for the UE.

[0198] Optionally, the sensing measurement report may include sensing measurement results, such as the sensing signal-to-interference ratio, the strength of the sensing interference signal, the interference time slot, and the offset within the time slot.

[0199] Taking the block error rate (BRR) as an example, the perceived measurement threshold can include the threshold corresponding to the BRR (e.g., 10%, 15%). The actual threshold can be different. When the perceived signal interference is greater than different thresholds (e.g., threshold a, threshold b, threshold c, etc.), the UE can generate different perceived measurement reports accordingly.

[0200] For example, in some implementations, the UE can generate a perception measurement report A based on the measured block error rate being greater than 10% or 15%.

[0201] In other implementations, the UE can generate a perception measurement report B based on the measured block error rate being greater than 10% and the interference not being significantly eliminated by communication interference suppression methods.

[0202] In other implementations, the UE can generate a measurement report C based on a measured block error rate greater than 10% and less than 15%.

[0203] In other implementations, the UE can generate a measurement report D based on the measured block error rate being greater than 15%.

[0204] In other implementations, the UE can generate a perception measurement report E based on the measured block error rate being greater than 15%, and the block error rate still being greater than 10% after processing with communication interference suppression.

[0205] In some embodiments, the sensing measurement report may also include information corresponding to communication sensing interference.

[0206] In some implementations, the information corresponding to communication-sensing interference can indicate the time-domain information of the interference, such as the time period during which the interference occurs (e.g., the first time period). That is, communication-sensing interference exists during the first time period.

[0207] In this application, based on the information corresponding to the communication sensing interference, BS1 adjusts the temporal resources of the communication task or sensing task accordingly, such as no longer using the first time period for the communication task or sensing task. This avoids communication sensing interference during the first time period.

[0208] In other implementations, the information corresponding to communication-sensing interference can indicate the beam information where interference exists, such as a communication beam (e.g., a first beam) and / or a sensing beam (e.g., a second beam) where interference exists. That is, the first beam used by the communication task is subject to communication-sensing interference, and the second beam used by the sensing task is subject to communication-sensing interference.

[0209] In this application, based on the information corresponding to the communication sensing interference, BS1 adjusts the beam resources of the communication task or sensing task accordingly, such as no longer using the first beam for the communication task or no longer using the second beam for the sensing task. This avoids communication sensing interference in the direction corresponding to the aforementioned beam.

[0210] In other implementations, the information corresponding to communication-sensing interference can indicate the frequency band where the interference exists, such as the first frequency band where the interference exists. That is, communication-sensing interference exists in this first frequency band.

[0211] In this application, based on the information corresponding to the communication sensing interference, BS1 adjusts the frequency domain resources of the communication task or sensing task accordingly, such as no longer using the first frequency band for the communication task or sensing task. This avoids communication sensing interference on the first frequency band.

[0212] The following example uses time-domain information indicating the presence of interference to illustrate communication-sensing interference.

[0213] For example, the communication-sensing interference information may include any one or more of the following:

[0214] The start and end times of the perceived interference, the duration of the perceived interference, the signal strength of the perceived interference, the period of the perceived interference, the duty cycle of the perceived interference, and the identifier of the time unit in which the communication perceived interference occurs.

[0215] Taking the timing information of the communication-sensing interference, including the identifier of the time unit where the communication-sensing interference occurs, as an example.

[0216] Understandably, in the time domain, communication and sensing tasks can communicate with the UE separately based on multiple time units. In some implementations, a single time unit can correspond to a time slot or a single symbol period or duration.

[0217] refer to Figure 3 This diagram illustrates a time unit distribution. The UE can perform communication tasks with BS1 in one or more time units from time unit 1 to time unit 5. The UE can also perform sensing tasks with BS2 in one or more time units from time unit 1 to time unit 5.

[0218] For example, BS1 can perform communication tasks with the UE in each of time units 1 to 5. BS2 can perform perception tasks with the UE in time units 2 and 4.

[0219] In this example, the UE can measure the communication-sensing interference for each time unit and determine the information of the time unit where communication-sensing interference exists based on the sensing measurement results.

[0220] For example, the UE can determine that the sensing measurement results acquired in time unit 2 and time unit 4 meet the sensing measurement threshold. In this way, the UE can determine that there is communication sensing interference in time unit 2 and time unit 4.

[0221] Therefore, the UE can include information from time unit 2 and time unit 4 in its perception measurement report. This allows the BS1 to be aware of communication perception interference in time units 2 and 4.

[0222] It should be noted that, as Figure 3 In the example, communication sensing interference exists in both time units 2 and 4 when the UE performs the sensing task. This result is determined by the UE based on the sensing measurement process. In other implementations, one or more time units when the UE performs the sensing task may not meet the sensing measurement threshold, i.e., there is no sensing measurement interference.

[0223] In some embodiments, the sensing measurement report may include information about sensing beams where communication sensing interference exists.

[0224] For example, after performing measurements on each sensing beam, the UE can obtain the sensing measurement results for each sensing beam. The UE can then determine the information of sensing beams experiencing communication sensing interference based on the sensing measurement threshold. For instance, the information of this sensing beam may include its beam identifier, beam index, and other information. In this way, the UE can send the information of the sensing beam experiencing communication sensing interference to BS1 in the sensing measurement report.

[0225] In some embodiments, the perception measurement report may include base station information corresponding to the perception task where communication perception interference exists. For example, if the UE determines that there is a perception beam that meets the perception measurement threshold among the perception beams emitted by BS2, it identifies BS2 as the base station corresponding to the perception task where communication perception interference exists. In this way, the UE can send the identification information of BS2 to BS1 in the perception measurement report.

[0226] The following example uses a sensing measurement report that includes information corresponding to communication sensing interference.

[0227] S205, the UE sends a perception measurement report to the first base station.

[0228] For example, the UE can send the perception measurement report to BS1 after generating the perception measurement report.

[0229] As described in S204, the sensing measurement report may include information corresponding to communication sensing interference. In some embodiments, the information corresponding to communication sensing interference may be used to indicate time-domain information of the communication sensing interference.

[0230] In some embodiments, the UE may periodically report the generated perception measurement reports.

[0231] In some embodiments, BS1 sends a request signaling, and UE reports a perception measurement report based on the request.

[0232] In other embodiments, the UE may send the perception measurement report to the BS1 after generating the perception measurement report.

[0233] It should be noted that in some other embodiments of this application, the UE may also send relevant information for resolving interference to the first base station.

[0234] 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.

[0235] 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.

[0236] In other embodiments, the UE may send both of the above items to the first base station together.

[0237] 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.

[0238] 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.

[0239] Alternatively, the second message may include only one of the aforementioned sensing measurement reports or information related to resolving interference.

[0240] S206. The first base station performs interference suppression processing based on the sensing measurement report.

[0241] 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.

[0242] 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.

[0243] In other implementations, the first base station may adjust or assist in adjusting the temporal resources for performing the sensing task. For example, the first base station may update the temporal resources for the sensing task to the terminal device performing the sensing task, wherein the adjusted temporal resources for the sensing task do not include the first time period where interference occurs. Alternatively, the first base station may send information about the time period where interference occurs to the base station performing the sensing task, so that the base station performing the sensing task can adjust the temporal resources for the sensing task, wherein the adjusted temporal resources for the sensing task do not include the first time period where interference occurs.

[0244] It is understandable that if the first base station determines, based on information reported by the UE (such as interference resolution information), that there is no (or possibly no) interference in other configured time-domain information, then the first base station can, according to the time-domain information indicated by the interference resolution information, perform communication tasks with the UE on time-domain resources where there is no (or possibly no) interference, or instruct the terminal device / base station performing the sensing task to perform communication tasks with the UE on time-domain resources where there is no (or possibly no) interference. Here, the configured time-domain resources where there is no interference can be time-domain resources determined to be interference-free after measurement; the configured time-domain resources where there is possibly no interference can be configured time-domain resources that have not been measured.

[0245] In other embodiments, the example is that the first base station determines that there is cross-link interference in the first frequency band based on the information reported by the UE.

[0246] In some implementations, the first base station can adjust the frequency domain resources used for communication tasks with the UE. The adjusted frequency domain resources do not include the first frequency band where interference exists. This allows the communication task to avoid the first frequency band that may be interfering.

[0247] In other implementations, the first base station may adjust or assist in adjusting the frequency domain resources used for the sensing task. For example, the first base station may update the frequency domain resources used for the sensing task to the terminal device performing the sensing task, wherein the adjusted frequency domain resources for the sensing task do not include the first frequency band where interference exists. Alternatively, the first base station may send information about interfering frequency bands to the base station performing the sensing task, enabling the base station to adjust the frequency domain resources for the sensing task, wherein the adjusted frequency domain resources for the sensing task do not include the first frequency band where interference exists.

[0248] Understandably, if the first base station determines, based on information reported by the UE (such as interference resolution information), that there is no (or possibly no) interference in other configured frequency domains, then the first base station can, according to the frequency domain information indicated by the interference resolution information, perform communication tasks with the UE on frequency domain resources where there is no (or possibly no) interference, or instruct the terminal device / base station performing the sensing task to perform communication tasks with the UE on frequency domain resources where there is no (or possibly no) interference. Here, the configured frequency domain resources where there is no interference can be frequency domain resources determined to be interference-free after measurement; the configured frequency domain resources where there is possibly no interference can be configured frequency domain resources that have not been measured.

[0249] In other embodiments, the example is that the first base station determines, based on information reported by the UE, that the first beam performing the communication task is subject to cross-link interference. For instance, the first base station can determine that interference exists in the first beam based on a measurement report reported by the UE.

[0250] In some implementations, the first base station can adjust the beam resources used for communication tasks with the UE. The adjusted beam resources do not include the first beam that is causing interference. This allows the communication task to avoid the first beam that may be causing interference. In some implementations, the first base station can determine from the interference resolution information reported by the UE that the third beam does not exist or may not have interference. In this way, the first base station can use beam resources including the third beam to perform subsequent communication tasks with the UE. Here, the third beam may be a beam that the UE determines does not have interference through measurement, or the third beam may be a beam of a configured communication task that the UE has not measured.

[0251] In other implementations, the first base station can adjust or assist in adjusting the beam resources used for sensing tasks.

[0252] For example, the first base station can update the beam resources for the sensing task to the terminal device performing the sensing task. The adjusted beam resources for the sensing task do not include beams that cause interference (such as the second beam). This second beam can be the beam used for the sensing task. The location pointed to by the second beam can be the same as or close to the location pointed to by the first beam used for the communication task. It is understood that the first base station can determine the information of the beams used for the sensing task (such as information including the second beam) through the sensing task resource configuration parameters obtained from BS2 in the aforementioned example. For the sensing task initiated by the terminal device, the sensing resources can be configured to the terminal device by the first base station, so the first base station can know the sensing resources including the second beam.

[0253] For example, the first base station can send information about the frequency band with interference to the base station performing the sensing task (such as BS2), so that the base station performing the sensing task can adjust the beam resources of the sensing task. The adjusted beam resources of the sensing task do not include the second beam with interference.

[0254] The following example, with reference to the accompanying drawings, illustrates the specific implementation of subsequent communication adjustments made by the first base station based on the information reported by the UE.

[0255] In some embodiments, the interference suppression process may include: BS1 adjusting the resource configuration used for communication tasks with the UE. The adjusted service resource configuration does not include periods of communication-aware interference.

[0256] Combination Figure 3 The example in the text is to take the information indicating time unit 2 and time unit 4 as examples of communication sensing interference.

[0257] BS1 can adjust the resource configuration for communication tasks with the UE. For example, BS1 can adjust the time-domain resource configuration for communication tasks with the UE. The adjusted time-domain resources for the communication task do not include... Figure 3 Time unit 2 and time unit 4 in the middle.

[0258] BS1 can send the adjusted resource configuration to the UE so that the UE can continue to communicate with BS1 according to the adjusted resource configuration.

[0259] For example, BS1 can configure the adjusted communication task resources to UE through Radio Resource Management Reconfiguration (RRC Reconfiguration) signaling, Media Access Control Layer Control Element (MAC CE), or Downlink Control Information (DCI) configuration.

[0260] In this way, since the adjusted communication task no longer takes place in time units 2 and 4, the sensing task will not interfere with the communication task. This improves the communication quality of both the sensing and communication tasks.

[0261] It is understood that the above embodiments provide various mechanisms for the UE to report interference-related information to the first base station. For example, the UE can report a measurement report to the first base station. Alternatively, the UE can report information related to resolving interference to the first base station. In subsequent embodiments of this application, the content reported by the UE and the processing mechanism of the first base station can also refer to the foregoing examples, and will not be elaborated further. The following description uses the example of the UE reporting a measurement report and the first base station adjusting resources for interference suppression based on the measurement report.

[0262] In other embodiments, the interference suppression process may include: BS1 sending information corresponding to communication-sensing interference to a second base station (such as BS2). This allows BS2 to adjust the sensing resource configuration used for sensing tasks with the UE. The adjusted sensing resource configuration does not include the time periods where communication-sensing interference occurs.

[0263] Combination Figure 3 The example in the text is to take the information indicating time unit 2 and time unit 4 as examples of communication sensing interference.

[0264] In some embodiments, the information corresponding to communication-sensing interference may include the information corresponding to time unit 2 and time unit 4.

[0265] For example, BS1 can send information about time unit 2 and time unit 4 to BS2. For instance, BS1 can send the identifiers of time unit 2 and time unit 4 to BS2. Or, BS1 can send the start and end times of time unit 2 and time unit 4 to BS2.

[0266] Therefore, BS2 can adjust the resource configuration for sensing tasks with the UE based on the information corresponding to time units 2 and 4. For example, BS2 adjusts the temporal resource configuration for sensing tasks with the UE based on the information corresponding to time units 2 and 4. The adjusted temporal resources for the sensing task do not include... Figure 3 Time unit 2 and time unit 4 in the middle.

[0267] In this way, since the adjusted sensing task no longer takes place in time units 2 and 4, the sensing task will not interfere with the communication task. This improves the communication quality between the sensing and communication tasks.

[0268] In this example, as Figure 3 The example shown is that time unit 2 and time unit 4 are subject to communication-sensing interference.

[0269] In other embodiments, BS1 can also flexibly adjust the time units of communication tasks based on the temporal distribution of time units where communication-sensing interference exists. For example, communication-sensing interference exists in time units 2 and 4. BS1 can adjust the time units of communication tasks to be odd-numbered time units. For instance, communication tasks are only performed in odd-numbered time units such as time units 1, 3, and 5. In this way, even if the UE continues to receive sensing signals in subsequent even-numbered time units, the communication quality will not degrade due to receiving data from communication tasks in the same time units.

[0270] In other embodiments, the information corresponding to communication-sensing interference may include information about the sensing beam where communication interference exists. For example, the information about the sensing beam may include index information of the sensing beam, etc.

[0271] Therefore, BS2 can adjust the beam configuration for sensing tasks with the UE based on the information of the sensing beam causing communication interference. The beam used for the adjusted sensing task will not include the sensing beam causing communication interference.

[0272] Thus, since BS2 no longer uses a beam that causes communication sensing interference to perform sensing tasks with the UE, the UE will not receive sensing tasks even in time units 2 and 4. This prevents the UE from receiving sensing tasks and thus ensuring that the quality of communication tasks is not affected.

[0273] refer to Figure 4 This is a schematic diagram of the interaction flow of a communication method provided in an embodiment of this application. BS1 is used as the first base station for communication tasks with the UE, and BS1 has sensing and measurement capabilities (e.g., the ability to send sensing and measurement signals); BS2 is used as the second base station for sensing tasks with the UE.

[0274] In this example, the UE can perform a first task (such as a communication task) with BS1. The UE can also receive a first signal. The first signal can correspond to a first sensing task. This first signal can be a signal directly emitted by BS2 when performing the first sensing task with the UE or a sensing target (such as a user) near the UE, and / or a signal reflected by the sensing target.

[0275] In this way, BS1 can monitor the signal quality of the communication task during communication with the UE. When the signal quality of the communication task deteriorates, according to the existing implementation scheme, BS1 can automatically try to adjust the current communication task to improve the signal quality of the communication task.

[0276] If BS1 is unable to improve the quality of the communication task on its own, it can trigger the sensing measurements of the communication system. For example, in this case, sensing measurements corresponding to S401, S402, and subsequent processing can be triggered.

[0277] In other implementations, BS1 can trigger a sensing measurement of the communication system when the signal quality of the currently ongoing communication task is below a preset threshold.

[0278] like Figure 4 As shown, the solution may include:

[0279] S401 and BS2 send perception task parameters to BS1.

[0280] In conjunction with the description in S202, in some embodiments, BS1 may obtain the sensing task parameters of BS2 before configuring the sensing measurement parameters to the UE.

[0281] The sensing task parameters may include at least one of the following: sensing waveform parameters, sensing beam information, sensing mode, and sensing transmit / receive time configuration information.

[0282] In some embodiments, BS1 can periodically acquire sensing task parameters sent by BS2. In other embodiments, BS1 can send corresponding request information to BS2 when the communication system needs to perform sensing measurements, so that BS2 can synchronize sensing task parameters with BS1 according to the request information.

[0283] S402 and BS1 send a UE awareness capability request to the UE. This awareness capability request is the same as the UE awareness capability request mentioned above.

[0284] S403, the UE sends UE awareness capability information to BS1. This awareness capability information is the same as the UE awareness capability information mentioned above.

[0285] For example, perception capability information may include perception capabilities. The UE's perception capabilities may include at least one of the following:

[0286] Sensing waveform; frequency domain bandwidth; time domain duration; time domain interval; guard interval; subcarrier interval.

[0287] S404 and BS1 send sensing measurement parameter indication information to the UE.

[0288] S405, UE sends an acknowledgment message to BS1.

[0289] Combination Figure 2As explained in the description, in some implementations of this example, BS1 can determine the perception measurement parameter indication information based on at least one of the following: the perception task parameters acquired in S401, the perception capability information acquired in S403, the communication resources that BS1 is currently communicating with the UE, and / or the communication resources that have been configured for the UE. In other implementations, the perception measurement parameters can be determined based on the first task and / or the configured resources of the first perception task.

[0290] In this way, BS1 can inform the UE of the sensing measurement parameters based on the acquired parameters and the sensing measurement parameter indication information. In some implementations, the sensing measurement parameters may correspond to the beam and / or frequency domain and / or time domain information that the UE needs to measure during subsequent sensing measurements. It is understood that since BS1 has already acquired the communication resources, sensing resources, and the UE's sensing capabilities, BS1 can configure the sensing measurement parameters to be determined based on the aforementioned information. For example, the resources to be measured indicated by the sensing measurement parameters may correspond to resources included in: the configured communication resources and / or sensing resources and / or resources within the UE's sensing capabilities and / or pre-configured resources.

[0291] For example, in some implementations, the resources to be measured corresponding to the sensing measurement parameters include configured communication resources. By configuring these sensing measurement parameters, BS1 can instruct the UE to measure the configured communication resources and determine information about resources with interference among them.

[0292] In some implementations, the resources to be measured corresponding to the sensing measurement parameters include the configured sensing resources. By configuring these sensing measurement parameters, BS1 can instruct the UE to measure the configured sensing resources and determine the information of the sensing resources that interfere with the communication task.

[0293] In some implementations, the resources to be measured corresponding to the perception measurement parameters include resources within the UE's perception capability range. Through the configuration of these perception measurement parameters, BS1 can instruct the UE to measure resources within its perception capability range and determine information about perception resources that interfere with communication tasks among the resources that the UE can perceive.

[0294] In some implementations, the sensing measurement parameters can be pre-configured.

[0295] For example, the sensing measurement parameters included in the sensing measurement parameter indication information may include at least one of the following:

[0296] The type of sensing measurement signal, the sensing measurement quantity, the sensing measurement interval, the sensing measurement threshold, and the number of sensing interferences.

[0297] Therefore, by configuring the sensing measurement parameter indication information, the UE can generate a corresponding first measurement report after performing subsequent sensing measurements, provided that the measurement results meet at least one threshold condition indicated by the sensing measurement parameters.

[0298] In some implementations, the threshold can be indicated by sensing measurement parameters. In other implementations, the threshold and the conditions corresponding to the threshold can be configured synchronously or asynchronously by BS1.

[0299] S406 and BS1 send sensing measurement signals to the UE.

[0300] S407, UE sends a perception measurement report to BS1.

[0301] For example, the UE can perform sensing measurements based on the sensing measurement signal and according to the configured sensing measurement parameters. It is understood that in this example, BS1 has sensing measurement capabilities. That is, BS1 can send a signal of the same type and / or resource configuration as the sensing signal for sensing measurements. In this way, BS1 can send a measurement signal simulating the sensing signal to the UE while continuing communication with the UE, so that the UE can determine whether the received measurement signal interferes with the ongoing communication. In some implementations, the type and / or resource configuration of the sensing measurement signal may correspond to the sensing measurement quantity that needs to be measured, as indicated by the sensing measurement parameters already configured by BS1 for the UE.

[0302] As a specific example, in some embodiments, the UE can perform sensing measurements separately for each time unit.

[0303] The sensing measurement report may include at least one of the following: sensing measurement results, information on communication sensing interference, information on the sensing beam used by the sensing task, and base station information corresponding to the sensing task.

[0304] In different embodiments, BS1 can execute the following S408 or S409 to avoid communication and perception interference between the communication task and the perception task, thereby improving communication quality.

[0305] S408 and BS1 send the adjusted communication task resources to the UE.

[0306] In this example, BS1 can adjust communication task resources based on the sensing measurement report. For example, it can adjust the time-domain resources during the communication task so that the adjusted time-domain resources do not include time periods where communication sensing interference exists.

[0307] BS1 can configure / update the adjusted communication task resources to the UE so that the UE can perform communication tasks with the UE through the adjusted communication task resources.

[0308] In S409, BS1 sends a perception measurement report to BS2. In some embodiments, BS1 can determine the perception resources for the adjusted perception task based on the information reported by the UE. Thus, in S409, BS1 can send the adjusted perception resources for the perception task to BS2.

[0309] S410 and BS2 use the adjusted perception task resources to perform perception tasks.

[0310] In this example, BS1 can send all or part of the information in the perception measurement report to BS2 so that BS2 can adjust the resource configuration in the perception task.

[0311] The adjusted resource configuration for the sensing task does not include time periods with communication sensing interference, and / or, the adjusted resource configuration for the sensing task does not include beams with communication sensing interference, and / or, the adjusted resource configuration for the sensing task does not include frequency points with communication sensing interference.

[0312] Therefore, during the execution of S410, BS2 can perform sensing tasks with the UE based on the adjusted sensing task resources, thereby avoiding interference with communication tasks and improving communication quality. When BS2 performs sensing tasks with other UEs (such as UE2), the adjustment of sensing task resources ensures that even if the UE performing the communication task receives the sensing signal sent by BS2, it will not interfere with the communication task.

[0313] It is understandable that the above Figure 4 The description uses BS1 communicating with the UE and BS2 performing a sensing task with the target as an example. In other embodiments, where BS1 has sensing and measurement capabilities, BS1 can be an integrated sensing device. That is, BS1 can also be used to perform sensing tasks with the UE. In this example, BS1 performs a sensing task with the UE. BS2 performs another sensing task with a target near the UE. If the time and frequency domain resources of these two sensing tasks overlap, mutual interference between the sensing tasks may occur. Similar to... Figure 4 In the example scheme, BS1 can determine information about resources that interfere with two sensing tasks by instructing the UE to perform sensing measurements. Based on this, BS1 can adjust the resources used for the sensing tasks performed by BS1 and the UE, or instruct BS2 to adjust the resources used for the sensing tasks with the sensing target, so that either sensing task avoids using the interfering resources.

[0314] The above Figure 4In the example, BS1 performs measurement and resource adjustments for subsequent communication and / or sensing tasks, which is used for communication tasks. In other embodiments, the functions of BS1 in the above example can also be performed by BS2 for sensing communication.

[0315] For example, refer to Figure 5 This is an interactive schematic diagram of another communication method provided in an embodiment of this application. In this example, BS2 can instruct the UE to perform sensing measurements. This scheme can be applied when BS1 does not have sensing measurement capabilities. In some other implementations, since BS2, as a sensing device, necessarily has the capability of sensing measurements (i.e., sending sensing measurement signals), this scheme can also be applied when BS1 has sensing measurement capabilities.

[0316] In some implementations, BS1 can execute the following... Figure 5 Prior to the illustrated scheme, BS2 performs communication tasks with the UE. Additionally, BS2 can perform sensing tasks with nearby sensing targets (or the UE). After detecting a decrease in the signal quality of the communication task, BS1 can attempt to improve the signal quality of the communication task using existing methods. If BS1 is unable to improve the signal quality of the communication task on its own, it can send corresponding indication information to BS2. BS2 can then trigger actions based on this indication information sent by BS1, such as... Figure 5 The sensor measurements and resource adjustments are shown.

[0317] Similar to Figure 4 The explanation in the text is as follows: Figure 5 In the example, the UE can perform a first task (such as a communication task) with BS1. The UE can also receive a first signal. The first signal can correspond to a first sensing task. This first signal can include signals directly emitted by BS2 when performing the first sensing task with the UE or a sensing target (such as a user) near the UE, and / or signals reflected by the sensing target.

[0318] like Figure 5 As shown, the solution may include:

[0319] S501 and BS2 send UE awareness capability requests to BS1, and BS1 sends UE awareness capability requests to the UE.

[0320] For example, the specific configuration of this UE perception capability request can be found in [reference]. Figure 4 The details of S402 are omitted here.

[0321] In other implementations of this application, BS2 can also directly send a UE awareness capability request to the UE through the data transmission link between BS2 and the UE.

[0322] In this example, BS2 can send the perception capability request to the UE through the communication link between BS1 and the UE.

[0323] S502, UE sends UE awareness capability information to BS1, and BS1 sends UE awareness capability information to BS2.

[0324] For example, the specific configuration of this UE perception capability information can be referred to Figure 4 The details of S403 will not be elaborated further.

[0325] In this example, BS2 can obtain UE perception capability information sent by UE through the communication link between BS1 and UE.

[0326] In other implementations of this application, the BS2 can also directly obtain the UE perception capability information sent by the UE through the data transmission link between the BS2 and the UE.

[0327] S503 and BS2 send sensing measurement parameter indication information to BS1, and BS1 sends sensing measurement parameter indication information to UE.

[0328] For example, the specific configuration of the sensing measurement parameter indication information can be referred to Figure 4 The details of S404 will not be elaborated further.

[0329] In this example, BS2 can send the sensing measurement parameter indication information to the UE through the communication link between BS1 and the UE.

[0330] In other implementations of this application, the BS2 can also directly send the sensing measurement parameter indication information to the UE through the data transmission link between the BS2 and the UE.

[0331] S504, UE sends an acknowledgment message to BS1, and BS1 sends an acknowledgment message to BS2.

[0332] For example, the specific configuration of this confirmation information can be found in [reference]. Figure 4 The details of S405 will not be elaborated further.

[0333] In this example, BS2 can obtain the confirmation information sent by the UE through the communication link between BS1 and the UE.

[0334] In other implementations of this application, the BS2 can also directly obtain the confirmation information sent by the UE through the data transmission link between the BS2 and the UE.

[0335] S505 and BS2 send sensing and measurement signals to the UE.

[0336] Sensing measurement signals can be used by the UE for sensing measurements. Unlike... Figure 4 As shown in S406, BS1 sends a sensing measurement signal to the UE through the communication link; in this example, BS2 can send the sensing measurement signal to the UE through the sensing link.

[0337] In some implementations, the sensing measurement signal can be different from the sensing signal that is performing the sensing task.

[0338] In other implementations, the sensing measurement signal can partially or fully reuse the resources of the sensing signal that is currently performing a sensing task.

[0339] S506, UE sends a perception measurement report to BS1, and BS1 sends a perception measurement report to BS2.

[0340] For example, the specific configuration of this perception measurement report can be found in [reference]. Figure 4 The details of S407 will not be elaborated further.

[0341] In this example, BS2 can obtain the UE perception measurement report sent by the UE through the communication link between BS1 and the UE.

[0342] In other implementations of this application, the BS2 can also directly obtain the UE perception measurement report sent by the UE through the data transmission link between the BS2 and the UE.

[0343] S507, BS2 sends the adjusted communication task resources to BS1, and BS1 sends the adjusted communication task resources to the UE.

[0344] S508 and BS2 use the adjusted perception task resources to perform perception tasks.

[0345] For example, the specific implementation of adjusting communication task resources and sensing task resources of BS2 in S507-S508 can be referred to the above description, and will not be repeated here.

[0346] Understandably, similar to Figure 4 Example of a solution in the example, such as Figure 5 In the implementation of the scheme shown, when the first task performed by BS1 and UE includes a perception task, then through this... Figure 5 With a similar approach, BS2 can effectively cooperate with BS1 and UE to perform sensing measurements and identify resources that interfere with each other in the two sensing tasks. Then, the resources of either sensing task can be adjusted to avoid interference between them.

[0347] Therefore, combined Figure 4 as well as Figure 5According to the scheme description in this application embodiment, the entity that performs the tasks of acquiring UE perception capabilities, cooperating with UE to conduct perception measurements, and adjusting task resources can be either BS1 performing the communication task or BS2 performing the perception task. In specific implementation, each of the above steps can also be partially performed by BS1 and BS2 respectively, thereby enabling BS1 and BS2 to cooperate with each other and avoid interference between the communication task and the perception task.

[0348] In the above description of the solutions provided in the embodiments of this application, the BS2 is used as an example to illustrate the perception task. In other embodiments of this application, the perception task may also be initiated by other devices. For example, the perception task may be initiated by UE2.

[0349] In this way, UE2 can perform sensing measurements on sensing targets based on the configured sensing resources. As described above, sensing targets can include active devices being sensed (such as other terminal devices) and passive objects being sensed (such as users).

[0350] The sensing resources used by UE2 can be the network equipment of the cell where UE2 is located, configured for UE2.

[0351] In some embodiments, as shown in the figure, UE1 and UE2 are within the cell coverage area of ​​the same base station (e.g., BS1). (See reference...) Figure 6 .

[0352] On the one hand, BS1 can be achieved through methods such as Figure 6 The communication link shown is used for communication tasks with UE1.

[0353] On the other hand, UE2 can be achieved through methods such as Figure 6 The sensing link shown performs sensing tasks with the sensing target. In some implementations, the sensing resources used by UE2 for sensing tasks may be configured for UE2 by BS1. In other embodiments, the sensing resources used by UE2 for sensing tasks may be configured for UE2 by other network devices.

[0354] In some examples, UE2 performs a sensing task using sensing resources configured via BS1. These sensing resources may 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.

[0355] In such Figure 6In the example above, when the sensing target is close to UE1, the sensing signal received by the sensing target is reflected and then received by UE1. Thus, this reflected sensing signal is an interference signal for UE1, potentially interfering with UE1's communication tasks. Correspondingly, in the sensing task, the signal reflected from the sensing target to UE2 may include not only the reflected sensing signal from the sensing target but also the signal of the communication task transmitted by BS1 after reflection by the sensing target. Therefore, the communication task may also interfere with the sensing task. This is the communication sensing interference or cross-link interference mentioned in the example above.

[0356] This application also provides a communication method, in such a way as Figure 6 In the scenario shown, it can effectively reduce or avoid cross-link interference.

[0357] For example, refer to Figure 7 This is a schematic diagram illustrating the interaction flow of another communication method provided in this application embodiment. It takes UE2 performing a sensing task, with both UE2 and UE1 within the coverage area of ​​BS1's cell, as an example.

[0358] Similar to Figure 4 or Figure 5 The explanation in the text is as follows: Figure 7 In the example, UE1 can perform a first task (such as 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 signals directly emitted by UE2 when performing the first sensing task with UE1 or a sensing target (such as a user) near UE1, and / or signals reflected by the sensing target.

[0359] like Figure 7 As shown, the solution may include:

[0360] S701 and BS1 send a UE awareness capability request to UE1.

[0361] S702, UE1 sends UE awareness capability information to BS1.

[0362] For example, the execution process of S701-S702 can be referred to Figure 4 The details of S402-S403 are not elaborated here.

[0363] It should be noted that in this example, UE2 is used to perform the perception task. BS1 can configure the perception resources for UE2 to perform the perception task before UE2 performs the perception task.

[0364] In some embodiments, the sensing resource may 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.

[0365] For example, BS1 can configure UE2 to perform sensing tasks in time period 1 and time period 2 (corresponding to time domain resources). BS1 can configure UE2 to perform sensing tasks using frequency band 1 and frequency band 2 (corresponding to frequency domain resources). BS1 can configure UE2 to perform sensing tasks using beam 1 and beam 2 (corresponding to beam resources).

[0366] The corresponding UE2 can use the pre-configured resources for perception tasks to perceive the target.

[0367] It is understandable that when UE2 has multiple configured sensing resources, UE2 can use a portion of these resources to perform sensing tasks at the same time.

[0368] For example, UE2 can perform sensing tasks using frequency band 1 and beam 1 during time period 1. Similarly, UE2 can perform sensing tasks using frequency band 2 and beam 2 during time period 2.

[0369] It should be noted that, without specific configuration, the combination of time-domain resources, frequency-domain resources, and beam resources can be determined by UE2 itself or configured by BS1.

[0370] S703 and BS1 send sensing measurement parameter indication information to UE1.

[0371] For example, the execution of S703 can be referred to the foregoing. Figure 4 S404 in the middle.

[0372] In some implementations of the embodiments of this application, BS1 can determine the sensing measurement parameters indicated in the sensing measurement parameter indication information based on the resource information currently being used by UE2.

[0373] For example, the sensing measurement parameters may include at least: the measurement type, sensing measurement quantity, and sensing measurement interval for the resources being used by UE2.

[0374] In this example, BS1 can obtain information about the resources currently being used by UE2 before executing S703.

[0375] In some implementations, UE2 can periodically report its current resource usage information to BS1. In other implementations, BS1 can send relevant request information to UE2 before executing S703, requesting UE2 to report its current resource usage. Correspondingly, UE2 can report its current resource usage information to BS1 based on the received request information.

[0376] In this way, BS1 sends the sensing measurement parameter indication information to UE1, which can instruct UE1 to perform interference measurements at least for the sensing resources that UE2 is using.

[0377] In other implementations of the embodiments of this application, BS1 can configure sensing measurement parameter indication information according to the current actual network conditions. Specific implementations are shown in S404 and related descriptions.

[0378] S704, UE1 sends an acknowledgment message to BS1.

[0379] S705, BS1 sends a sensing measurement signal to UE1. In some implementations, this sensing measurement signal may be sent by UE2, which performs the sensing task. For example, BS1 may instruct UE2 to send a sensing measurement signal corresponding to the sensing measurement parameters.

[0380] S706, UE1 sends a perception measurement report to BS1.

[0381] For example, the processing mechanism of S704-S706 can be referred to Figure 4 S405-S407 in the series.

[0382] Therefore, UE1 can perform sensing communication interference measurement under the configuration of BS1, thereby confirming information about the resources where interference exists.

[0383] 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.

[0384] 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.

[0385] In other embodiments, BS1 can determine the beam information where interference exists. For example, the beam information where interference exists includes: beam 1.

[0386] 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.

[0387] 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.

[0388] S707 and BS1 send the adjusted communication task resources to UE1.

[0389] For example, BS1 may no longer use resources that cause interference to perform communication tasks with UE1.

[0390] 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.

[0391] 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.

[0392] For example, if the interfering resource includes beam 1, then BS1 will no longer use beam 1 to communicate with UE1, but will instead use other beam resources. Correspondingly, BS1 can send the adjusted communication task's beam resources (e.g., excluding beam 1) to UE1 so that UE1 can communicate with BS1 using those beam resources.

[0393] S708 and BS1 send the adjusted perception task resources to UE2.

[0394] For example, BS1 can adjust the perception task resources, and the adjusted perception task resources may not include resources that cause interference. BS1 can also send the adjusted perception task resources to UE2 so that UE2 can perceive the target based on the adjusted perception task resources.

[0395] For example, if the resources causing interference include time period 1, then the adjusted sensing task resources may not include time period 1. After BS1 sends the adjusted sensing task resources to UE2, UE2 can then stop using time period 1 for sensing tasks.

[0396] For example, if the resources causing interference include frequency band 1, then the adjusted sensing task resources may not include frequency band 1. After BS1 sends the adjusted sensing task resources to UE2, UE2 can then stop using frequency band 1 for sensing tasks.

[0397] For example, if the resource causing interference includes beam 1, then the adjusted sensing task resource may not include beam 1. After BS1 sends the adjusted sensing task resource to UE2, UE2 can then stop using beam 1 for sensing tasks.

[0398] In other embodiments, BS1 may send unavailable sensing task resources to UE2. For example, consider a time period 1 where interference exists. BS1 may send time-domain resources for unavailable sensing tasks, including time period 1, to UE2. Thus, UE2 can, according to the configuration of BS1, no longer use time period 1 for sensing tasks. Similarly, BS1 may configure unavailable beam resources and / or frequency-domain resources to UE2, thereby allowing UE2 to stop using these unavailable beam resources and / or frequency-domain resources for sensing tasks.

[0399] Understandably, similar to Figure 4 as well as Figure 5 Example of a solution in the example, such as Figure 7 In the implementation of the scheme shown, when the first task performed by BS1 and UE1 includes a perception task, then through this... Figure 7 With a similar implementation, UE2 can effectively cooperate with BS1 and UE1 to perform sensing measurements and identify resources that interfere with each other in the two sensing tasks. Then, the resources of either sensing task can be adjusted to avoid interference between the sensing tasks.
