[0030] Compared with the prior art, the technical solutions of the embodiments of this disclosure have the following beneficial effects:

[0031] The sensing initiator sends a sensing signal, which is associated with identification information. The identification information is used to identify the identity of the interference source. The first device receives the sensing signal and / or echo signal. The echo signal is the signal generated when the sensing signal acts on the sensing target. The sensing receiver determines the interference status information based on the identification information and reports it to the SF network element.

[0032] Compared to existing technologies that only design interference identification schemes for interference between network devices in communication systems, this implementation scheme proactively carries self-identification information in the transmitted sensing signal. This allows the first device to accurately identify the sensing initiator (which could be a UE or a network device) as the interference source when the sensing signal interferes with external systems (e.g., the first device). Furthermore, the first device can report the acquired identity information (i.e., identification information) of the sensing initiator to the SF network element, enabling the SF network element to accurately determine the interference source and execute corresponding interference suppression strategies. This achieves enhanced interference identification in the sensing scenario. Attached Figure Description

[0038] As mentioned in the background section, the types of interference in future integrated communication and sensing networks will be much more complex, such as interference between sensing and communication, and interference between sensing devices. In order to better cope with interference, it is necessary to accurately identify the source of interference, such as precisely knowing which network device or user equipment (UE) is sending the sensing signal.

[0039] In previous research on fifth-generation mobile communications (5G), only the Remote Interference Management Reference Signal (RIM-RS) was designed specifically to assess interference between network devices (e.g., base stations). If a UE, acting as a sensing node, causes interference to other devices, the existing communication system cannot identify the UE as the interference source and therefore cannot implement corresponding interference suppression strategies.

[0040] To solve the above technical problems, the sensing initiator sends a sensing signal, which is associated with identification information. The identification information is used to identify the identity of the interference source. The first device receives the sensing signal and / or echo signal, which is the signal generated when the sensing signal acts on the sensing target. The sensing receiver determines the interference status information based on the identification information and reports it to the SF network element.

[0041] As described above, in this implementation scheme, the sensing initiator actively carries self-identification information in the transmitted sensing signal. This allows the first device to accurately identify the sensing initiator (which can be a UE or a network device) as the interference source when the sensing signal interferes with external systems (e.g., the first device). Furthermore, the first device can report the acquired identity information (i.e., identification information) of the sensing initiator to the SF network element, enabling the SF network element to accurately determine the interference source and execute corresponding interference suppression strategies. Thus, interference identification enhancement in sensing scenarios can be achieved, ensuring that different sensing services, sensing services, and communication services can operate without interference.

[0042] The sensing service in this disclosure refers to the service provided by a sensing node (also called a sensing device) with sensing capabilities to sense a target and obtain relevant information about the target. The sensing service can be applied in the Internet of Things (IoT) field. In some embodiments, the sensing service may include speed sensing services for estimating the moving speed of the target. In other embodiments, the sensing service may include distance sensing services for estimating the distance to the target. The sensing service is a service provided by the sensing scenario of a communication-sensing integrated system (referred to as integrated sensing). In the sensing scenario, the sensing node, acting as the sensing initiator, sends a sensing signal, and the sensing node, acting as the sensing responder, receives the signal generated after the sensing signal is applied to the target and processes the received signal using a sensing algorithm. The processed sensing result can be reported to the base station or sensing function (SF) through the uplink channel, or it can be used by the sensing node that received the signal, or it can be used by other UEs. The sensing function can be a core network element (denoted as an SF element). The sensing node can be a UE or a network device. The difference between different sensing scenarios lies in the execution entity of the sensing node.

[0043] In single-site sensing mode, the sensing initiator and the sensing receiver are the same sensing node. That is, the sensing node itself sends sensing signals and receives the signals returned after the sensing signals are applied to the sensing target. The signal received by the sensing receiver in single-site sensing mode is denoted as the echo signal. Sensing types using single-site sensing mode can include UE-initiated and network-device-initiated sensing.

[0044] In dual-site sensing mode, the sensing initiator and sensing receiver can be different sensing nodes. That is, sensing node A sends a sensing signal, and sensing node B receives the signal generated after the sensing signal is applied to the sensing target. The signal received by the sensing receiver in dual-site sensing mode is usually called the received signal. In this embodiment, for ease of description, the signals received by the sensing receiver in both single-site and dual-site sensing modes are collectively referred to as echo signals. Sensing types using dual-site sensing mode can include: network device sending and UE receiving, network device a sending and network device b receiving, UE sending and network device receiving, and UEa sending and UEb receiving. For ease of description, in this embodiment, the sensing initiator is referred to as end a, and the sensing receiver is referred to as end b. In some embodiments, for the a-send-b-receive sensing method, end a can also receive the sensing echo signal; that is, in this case, the sensing initiator can perform single-site sensing mode while simultaneously performing dual-site sensing mode.

[0045] In multi-static sensing mode, at least one of the sensing initiator and sensing receiver has a multiple number of sensing nodes. That is, multiple sensing nodes A send sensing signals, and one or more sensing nodes B receive the signals generated after each sensing signal is applied to the sensing target; or, one or more sensing nodes A send sensing signals, and multiple sensing nodes B receive the signals generated after at least one sensing signal is applied to the sensing target. Sensing types using multi-static sensing mode can include: one network device sending and multiple network devices receiving; one network device sending and multiple UEs receiving; one UE sending and multiple UEs receiving; one UE sending and multiple network devices receiving; multiple network devices sending and one network device receiving; multiple UEs sending and one network device receiving; multiple UEs sending and one UEb receiving; and multiple network devices sending and one UE receiving.

[0046] For cooperative perception mode, it can be a combination of any two or more of the aforementioned perception scenarios. In autonomous driving applications, cooperative perception enables vehicles to share information to perceive the environment beyond their line of sight and field of view. For example, vehicles within the same area share collective perception information to collaboratively perceive the environment; this is called cooperative perception or collaborative sensing. Perception types using cooperative perception mode can include: multiple UEs or network devices performing mono-station perception, multiple pairs of perception nodes performing bi-station perception, a single UE or network device performing mono-station perception and a pair of perception nodes performing bi-station perception, and a single perception node performing mono-station or bi-station perception on multiple sub-bands.

[0047] In this embodiment of the disclosure, the resources specifically refer to sensing resources, that is, resources used for sensing. Sensing signals and / or echo signals are transmitted via sensing resources.

[0048] The communication resources in this embodiment can be resources used for communication, such as time-domain resources for transmitting data, time-domain resources for transmitting the Physical Uplink Control Channel (PUCCH), and time-domain resources for transmitting the Physical Downlink Shared Channel (PDSCH). The sensing resources can be resources used for sensing, such as time-domain resources for actual sensing (also called sensing reference signal resources), and service time-domain resources (e.g., service symbols) for establishing a link between the UE and the network device. The sensing resources and communication resources can be time-division multiplexed.

[0049] The first device in this embodiment refers to a device that is interfered with by the sensing initiator. That is, the sensing initiator is the interference source of the first device, and the sensing signal sent by the sensing initiator interferes with the communication services and / or sensing services of the first device. The first device can be a UE or a network device.

[0050] For example, the sensing initiator can be base station A. The sensing signal sent by base station A may interfere with UEs in other base stations (e.g., base station B) or other cells (i.e., cells other than those managed by base station A). Accordingly, base station B and UEs in other cells can all serve as the first device to execute this implementation scheme.

[0051] To make the above-mentioned objectives, features and beneficial effects of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0052] Figure 1 This is a signaling interaction diagram of a communication method according to an embodiment of this disclosure.

[0053] In specific implementation, in the communication method provided by the following steps (denoted as S) 101 to S103, the steps implemented by the sensing initiator can be executed by a chip with communication function in the UE / network device that serves as the sensing initiator, or by a baseband chip in the UE / network device that serves as the sensing initiator; the steps implemented by the first device can be executed by a chip with communication function in the UE / network device that serves as the first device, or by a baseband chip in the UE / network device that serves as the first device; the steps implemented by the SF network element can be executed by a chip with communication function in the SF network element, or by a baseband chip in the SF network element.

[0054] This implementation scheme is applicable to sensing scenarios in single-site sensing mode, dual-site sensing mode, collaborative sensing mode, and multi-site sensing mode. Depending on the sensing scenario, the number of sensing initiators can be one or more. Furthermore, for any sensing initiator in the current sensing scenario, this implementation scheme can be executed to send a sensing signal carrying self-identification information. Next, the interaction process between a single sensing initiator and the first device / SF network element will be used as an example to specifically illustrate this implementation scheme.

[0055] Specifically, refer to Figure 1 The communication method described in this embodiment may include the following steps:

[0056] S101, the sensing initiator sends a sensing signal. Correspondingly, the first device receives the sensing signal and / or echo signal. The sensing signal is associated with identification information, which is used to identify the source of interference.

[0057] More specifically, the sensing signal may include a sensing reference signal, specifically a reference signal used for sensing. For example, the sensing reference signal may be selected from any of the following: Channel State Information-Reference Signal (CSI-RS), Positioning Reference Signal (PRS), Sounding Reference Signal (SRS), or RIM-RS (e.g., RS-1 or RS-2 as described below).

[0058] After the sensing signal is emitted, besides generating an echo signal that acts on the sensing target and is received by the sensing receiver to complete the sensing operation, the sensing signal itself may also be received by other devices (e.g., the first device). In this case, the sensing signal may be interference for the first device. Similarly, the echo signal may also be received by other devices (e.g., the first device) during its transmission to the sensing receiver. In this case, the echo signal also constitutes interference for the first device. Therefore, the sensing signal in this embodiment is further associated with identification information, specifically the self-identification information of the interference source, which is used by the device receiving the sensing signal and / or the echo signal (e.g., the first device) to identify the identity of the interference source. Thus, when the sensing signal or the corresponding echo signal interferes with the first device, the first device can accurately determine the identity of the interference source.

[0059] Furthermore, the methods for associating identification information with sensing signals can include: directly carrying information related to the identity of the interference source in the sensing signal; or determining information related to the interference source by transmitting resources of the sensing signal. Since the echo signal is the signal generated after the sensing signal acts on the sensing target, it can also be associated with identification information.

[0060] Furthermore, the interference source can be selected from: the sensing initiator and the cell to which the sensing initiator belongs. For example, when the sensing initiator is a network device, the sensing signal sent by the network device may cover the entire cell under the jurisdiction of the network device. Therefore, the cell to which the network device belongs itself constitutes a large interference source for the first device.

[0061] In some embodiments, the first device may receive a sensing signal, and this sensing signal may interfere with the first device. In this example, the first device may be close to the interference source and directly receive the sensing signal.

[0062] In some embodiments, the first device may receive an echo signal, and this echo signal may interfere with the first device. In this example, the first device may be some distance away from the interference source but close to the sensing target (or sensing receiver). In this case, the first device may not be interfered with by the sensing signal but can receive the echo signal. Therefore, the sensing operation performed by the sensing initiator and sensing receiver still interferes with the first device.

[0063] In some embodiments, the first device may receive both the sensing signal and the echo signal, and be interfered with by both signals simultaneously. In this example, the first device is close to the interference source and the sensing receiver (or sensing target), so it may be interfered with by multiple signals simultaneously.

[0064] Further reference Figure 1 The communication method described in this embodiment may further include the following steps:

[0065] S102, the first device determines the interference status information based on the identification information and reports it to the SF network element via higher-layer signaling, a Medium Access Control-Control Element (MAC-CE), or Uplink Control Information (UCI). The SF network element then receives the interference status information. Alternatively, the first device can also report the interference status information to network equipment (e.g., a base station) via higher-layer signaling, MAC-CE, or UCI, and the base station receives the interference status information.

[0066] Specifically, the interference status information can include the identity of the interference source, enabling SF network elements to accurately identify the interference source. Upon receiving the interference status information, the SF network element retrieves the identity of the interference source and then interacts with the interference source to instruct it to adopt appropriate interference suppression strategies.

[0067] In one specific implementation, the interference source can be a network device, and the first device can include other network devices or UEs from other cells (i.e., the cell to which the network device other than the network device acting as the interference source belongs). Furthermore, the sensing signal can include RIM-RS; this implementation enhances RIM-RS to better suit interference identification in sensing scenarios.

[0068] Specifically, RIM-RS can be selected from Type 1 RIM-RS (denoted as R1 or RS-1) and Type 2 RIM-RS (denoted as R2 or RS-2). In the prior art, RS-1 is sent by the interfered party (corresponding to the first device in this embodiment) to the interference source to assist the interference source in identifying that it is causing remote interference to the interfered party and to detect / reduce how much uplink resources of the interfered party are affected by the interference source; RS-2 is sent by the interference source to the interfered party to assist the interfered party in determining whether the interference phenomenon still exists. Both RS-1 and RS-2 carry the identification number of the interference source (e.g., base station). Therefore, this embodiment adopts the configuration method such as the sequence of RIM-RS specified in the existing protocol so that the sensing signal (i.e., RIM-RS) sent by the network device as the sensing initiator is associated with identification information.

[0069] In other words, this specific implementation uses the sequence configuration of RS-1 and RS-2, and designs both types of RIM-RS to be transmitted by network devices acting as interference sources. For example, the network device acting as the sensing initiator can choose either RS-1 or RS-2 as the sensing signal for transmission. Furthermore, in this specific implementation, RS-1 and RS-2 are also used for sensing; that is, the echo signal generated after RS-1 or RS-2 acts on the sensing target carries the sensing result of the sensing target.

[0070] In some embodiments, RIM-RS can be classified into the following three types through pre-configuration, pre-definition, or protocol specification: the first type is RIM-RS used in traditional communication scenarios; the second type is RIM-RS used to identify the identity of interference sources in sensing scenarios; and the third type is RIM-RS used purely for sensing.

[0071] Specifically, the first type of RIM-RS can follow the relevant provisions of the existing protocol, namely RS-1 sent by the interfered party and RS-2 sent by the interference source.

[0072] The second and third types of RIM-RS can be newly added RIM-RS for the sensing scenario. Among them, the second type of RIM-RS is the sensing signal sent by the sensing initiator in S101 of this implementation scheme, which is used for the first device to identify the identity of the interference source; the third type of RIM-RS may not be associated with identification information, but is dedicated to sensing the sensing target.

[0073] Furthermore, each network device preferably maintains consistency when configuring the periodicity of the second type of RIM-RS.

[0074] In some embodiments, the resources corresponding to RIM-RS can occupy at least two time units in the time domain. A time unit can be the communication granularity between the UE and network devices in the time domain. For example, a time unit can be a time slot, a mini-slot (a shorter duration unit than a time slot), a subframe, a symbol, or a frame. Compared to existing technologies where the resources corresponding to RIM-RS typically occupy only one Orthogonal Frequency Division Multiplexing (OFDM) symbol, in this example, the resources corresponding to RIM-RS can be extended to occupy two or even more consecutive OFDM symbols in the time domain. The more time units the resources corresponding to RIM-RS occupy in the time domain, the higher the accuracy of velocity estimation for the sensed target based on RIM-RS.

[0075] In some embodiments, the step of transmitting the sensing signal in S101 may specifically include repeatedly transmitting the RIM-RS. Specifically, the sensing initiator can increase the length of the RIM-RS in the time domain by repetition to improve the sensing effect.

[0076] In some embodiments, the bandwidth occupied by the resources corresponding to RIM-RS in the frequency domain can exceed the bandwidth of a single Bandwidth Part (BWP). That is, RIM-RS can be transmitted across BWPs. The larger the bandwidth occupied by the resources corresponding to RIM-RS in the frequency domain, the higher the accuracy of distance estimation for the sensed target based on RIM-RS.

[0077] In some embodiments, the resources corresponding to RIM-RS can be located in any one or more time units within a first time length. The first time length can be the communication granularity at the next higher level than a time unit; assuming a time unit is a symbol, the first time length can be a time slot. Compared to the prior art where the transmission position of RIM-RS is fixed at the last few symbols of a time slot, the transmission position of RIM-RS used for sensing in this specific embodiment can be more flexible and is no longer limited to the last few symbols of a time slot.

[0078] For example, the resources corresponding to RIM-RS can be located in the last two symbols of slot 1 and the first three symbols of slot 2.

[0079] For example, the resource corresponding to RIM-RS can be located in the last three symbols of slot 0. Alternatively, the resource corresponding to RIM-RS can be located in the 8th to 10th symbols of slot 0.

[0080] For example, the resource corresponding to RIM-RS can be located in the first two symbols of slot 1.

[0081] In one specific implementation, compared to the existing RIM-RS which is configured on a unit basis (also called a carrier component, abbreviated as CC) or BWP, the RIM-RS in this implementation can be configured on a resource basis or a resource set. A resource set may include one or more resources.

[0082] Specifically, at least one RIM-RS can correspond one-to-one with at least one resource. In other words, the resource itself can also serve as identification information; the identity of the interference source can be determined based on the resource that sent the RIM-RS.

[0083] Alternatively, at least one RIM-RS can correspond one-to-one with at least one resource set. That is, all resources belonging to the same resource set share a single RIM-RS. Therefore, more suitable resources can be flexibly selected to transmit the RIM-RS according to the needs of the current sensing service. For example, when performing speed sensing services, resources occupying more time units in the time domain can be selected to transmit the RIM-RS; while when performing distance sensing services, resources occupying more bandwidth in the frequency domain can be selected. Furthermore, using any resource in the resource set to transmit a RIM-RS, the identity of the interference source can be determined through the RIM-RS itself and the resources used.

[0084] Further, S101 may specifically include: the sensing initiator transmitting the corresponding RIM-RS using a first resource. Correspondingly, the sensing receiver using the first resource receives the echo signal generated after the corresponding RIM-RS acts on the sensing target. The first resource is selected from at least one resource or at least one set of resources.

[0085] Different RIM-RS carry different identification information to identify different interference sources. Accordingly, the sensing initiator determines the corresponding RIM-RS based on its own interference source and uses the resource corresponding to that RIM-RS to transmit it. For example, base station A uses resource 1 corresponding to RIM-RS a (carrying the identifier of base station A) to transmit RIM-RS a, and base station B uses resource 2 corresponding to RIM-RS b (carrying the identifier of base station B) to transmit RIM-RS b.

[0086] In some embodiments, the network device acting as the sensing initiator may further perform the step of: sending first information, the first information being used to configure the at least one RIM-RS.

[0087] Specifically, the network device can broadcast first information, which can be received by other network devices or UEs (i.e., potential first devices) located near the network device to obtain configuration-related information of at least one RIM-RS.

[0088] Furthermore, in response to receiving the first information, when the first device subsequently receives the sensing signal and / or echo signal in S101, it can also determine the identity of the interference source based on the resources used during reception (i.e., the first resource).

[0089] Therefore, in addition to the network device identification number carried by RIM-RS itself, identification information can also be indicated by transmitting the first resource of RIM-RS, so that the first device can more accurately obtain the identity of the interference source.

[0090] In some embodiments, for each RIM-RS in at least one RIM-RS, the first information may also be used to configure at least one Cyclic Prefix (CP) type corresponding to the RIM-RS, or the first information may also be used to configure the number of time units included in the resource corresponding to the RIM-RS within a first time length.

[0091] Specifically, the loop prefix type can include the length of the loop prefix (i.e., the CP length), and different loop prefix types can correspond to different CP lengths. Thus, different sensing business requirements can be adapted by modifying the CP.

[0092] Furthermore, the resource corresponding to the same RIM-RS can correspond to at least one candidate cyclic prefix type, where different candidate cyclic prefix types are associated with different sensing services. In S101, the network device can select a suitable cyclic prefix type from at least one candidate cyclic prefix type according to the sensing service currently in progress (or to be in progress), and then send the RIM-RS based on the selected cyclic prefix type.

[0093] Furthermore, the first information may include at least one of the following: the cyclic prefix type corresponding to the resource; the number of time units included in the resource within the first time length. For example, the first information can be used to configure the resource's time-domain location (including the time-domain start position and / or time-domain end position), frequency-domain location (including the frequency-domain start position and / or frequency-domain end position), and the number of time units included within the first time length. Based on the number of symbols included in a configured time slot, the time interval between adjacent symbols (i.e., the CP length) can be determined. The fewer the number of symbols included in a time slot, the larger the CP length. For example, the number of symbols included in a time slot can be modified to 11, 10, 9, 8, 7, 6, etc.

[0094] Furthermore, the length of a single time unit can be configured through protocol predefined or configuration information.

[0095] Alternatively, the first information can be used to configure the time-domain location (including the time-domain start and / or time-domain end), frequency-domain location (including the frequency-domain start and / or frequency-domain end), and CP length of the resource. Based on the configured CP length, the number of symbols included in a time slot can be determined.

[0096] For example, the type of cyclic prefix associated with a sensing service can be determined based on the detection distance required by the sensing service. Specifically, the farther away the sensing target is (i.e., the longer the detection distance), the longer the CP length corresponding to RIM-RS, and the fewer time units (e.g., symbols) included in the first time length (e.g., time slot). Thus, for any type of sensing service, it is possible to more reliably ensure that the sensing signal reaches the sensing receiver within a single CP range, thereby eliminating inter-symbol interference.

[0097] In a typical application scenario, refer to Figure 2 The network device, acting as the sensing initiator, performs operation s1 to send a RIM-RS. Upon receiving the RIM-RS, the first device can identify the interference source, for example, the network device's identifier. Further, the first device performs operation s2 to report interference status information to the SF network element, which carries the network device's identifier. Upon receiving the interference status information, the SF network element can perform operation s3 to instruct the network device to perform interference handling, for example, by instructing the network device to apply a remote interference mitigation scheme.

[0098] In some embodiments, in response to an instruction based on an SF network element to perform corresponding interference handling, the network device may also perform operation s4 to report the interference status. The interference status is used to assist the first device in determining whether the interference phenomenon still exists.

[0099] Therefore, it is possible to enhance the identification of interference from network devices in the sensing scenario, enabling the first device and SF network element to accurately identify the sensing signals from the network device side.

[0100] In one specific implementation, the sensing initiator can be a UE, and the sensing signal can include a first channel sounding reference signal, which is a channel sounding reference signal using a gold sequence. For example, the first signal sounding reference signal can be a sensing reference signal other than SRS, such as CSI-RS, PRS, etc.

[0101] Furthermore, the initial scrambling sequence (C) of the first channel detection reference signal init The scrambling sequence can carry identification information. For example, identification information can be added as a calculation term to the calculation formula of the initial scrambling sequence. By adding identification information to the initial scrambling sequence, it is easier for the first device (e.g., other network devices) to identify it.

[0102] For example, the identification information may be selected from at least a portion of the following: the cell identifier (Cell-ID) of the cell to which the interference source belongs, the cell radio network temporary identity (C-RNTI) of the cell to which the interference source belongs, the random access radio network temporary identity (RA-RNTI) of the interference source, the temporary radio network temporary identity (T-RNTI) of the interference source, the identification information of the network device, and the identification information of the UE. Selecting at least a portion of any of the above parameters for identification information may mean that, considering that some parameters have a large number of bits that cannot be accommodated in the initial scrambling sequence, a portion of the value of the parameter is added to the initial scrambling sequence. Therefore, it is not necessary to change the number of bits in the initial scrambling sequence, which helps to reduce signaling overhead.

[0103] The identification information of network devices can be, for example, the identity identifier (ID) of a base station, used to uniquely identify the base station. Specifically, when the interference source is a network device, the identification information of the network device can be carried as identification information in the sensing signal and transmitted.

[0104] The UE's identification information can be, for example, its ID, such as the International Mobile Equipment Identity (IMEI) or a Universally Unique Identifier. When the UE acts as a sensing initiator, it can carry its own identification information in the sensing signal so that the first device can identify the UE.

[0105] In some embodiments, the action of the UE, acting as the sensing initiator, sending a sensing signal in S101 can be performed after the C-RNTI of the cell to which the interference source belongs has been allocated. That is, after the UE initially joins a cell, it waits for the cell's network equipment to allocate a C-RNTI before sending a first channel sounding reference signal to perform sensing services.

[0106] Furthermore, during periods when no C-RNTI is assigned, the UE may consider disabling the sensing function. Alternatively, the UE may instead use RA-RNTI or T-RNTI added to the first channel sounding reference signal as identification information.

[0107] In one variation, the sensing initiator can be a UE, and the sensing signal can include a first channel sounding reference signal, which is a channel sounding reference signal using a gold sequence. For example, the first signal sounding reference signal can be a sensing reference signal other than SRS, such as CSI-RS, PRS, etc.

[0108] Furthermore, the resources corresponding to the first channel sounding reference signal can be associated with the interference source.

[0109] For example, the time-frequency domain location of the resources used to transmit the first channel sounding reference signal can have cell-specific attributes or UE-specific attributes within the cell. The time-domain location, frequency-domain location, sequence resources, or any combination thereof of the resources used by the UE, as the sensing initiator, to transmit the first channel sounding reference signal can uniquely identify the interference source. In S102, in response to receiving the first channel sounding reference signal, the first device can determine the corresponding identification information based on the resources used to receive the signal, generate interference status information based on the identification information, and report it to the SF network element, thereby identifying the interference source.

[0110] Therefore, by explicitly or implicitly carrying self-identification information in the sensing signal, the first device in the sensing scenario can accurately identify the sensing signal on the UE side.

[0111] In one specific implementation, the sensing initiator can be a UE, and the sensing signal can include a second channel sounding reference signal, which is a channel sounding reference signal using a ZC sequence. For example, the second channel sounding reference signal can be an SRS.

[0112] Furthermore, the ZC sequence used in the second channel sounding reference signal can carry identification information. For example, the ZC sequence itself can contain identification information; different UEs, different cells, or different base stations can use different ZC sequences or different groups of ZC sequences. Therefore, the identity of the interference source can be determined based on the ZC sequence used in the second sounding reference signal. Correspondingly, the association between the first device's ZC sequence and identification information can be indicated through pre-configuration, pre-definition, or other methods.

[0113] Alternatively, identification information can be added during the initialization of the scrambling sequence of the second channel sounding reference signal. For example, identification information can be added to any formula or base sequence during the generation of the ZC sequence to associate the ZC sequence with the identity of the interference source. The identification information can be selected from at least a portion of at least one of the following: the Cell-ID of the cell to which the interference source belongs, the C-RNTI of the cell to which the interference source belongs, the RA-RNTI of the interference source, and the T-RNTI of the interference source.

[0114] Alternatively, the resources corresponding to the second channel detection reference signal can be associated with the interference source. For example, the identity information of the interference source can be added through time domain resources, frequency domain resources, code domain resources, or any combination of the three, so that the UE, as the sensing initiator, carries self-identification information in the sensing signal it transmits.

[0115] Therefore, by explicitly or implicitly carrying self-identification information in the sensing signal, the first device in the sensing scenario can accurately identify the sensing signal on the UE side.

[0116] In a typical application scenario, refer to Figure 3The UE joins a cell managed by the network device, and the network device performs operation s1 to allocate a C-RNTI to the UE. In response to receiving the C-RNTI, the UE, acting as the sensing initiator, performs operation s2 to send a sequence corresponding to the CSI-RS (or SRS or PRS) with the C-RNTI added. In response to receiving the CSI-RS (or SRS or PRS), the first device can determine the identity of the interference source based on the sequence used in the CSI-RS (or SRS or PRS), for example, the C-RNTI allocated to the UE by the network device. Further, the first device performs operation s3 to report interference status information to the SF network element, which carries the C-RNTI of the cell to which the UE belongs. In response to receiving the interference status information, the SF network element can perform operation s4 to instruct the UE to perform interference handling, for example, instructing the UE to apply a remote interference mitigation scheme.

[0117] In some embodiments, in response to an instruction based on the SF network element to perform corresponding interference processing, the UE can also perform operation s5 to report the interference status. The interference status is used to assist the first device in determining whether the interference phenomenon still exists.

[0118] Therefore, it is possible to enhance the identification of interference from network devices in the sensing scenario, enabling the first device and SF network element to accurately identify the sensing signals from the network device side.

[0119] In one variation, the UE's need to perform awareness services may be so urgent that it needs to send the awareness signal before obtaining the C-RNTI allocated by the network device. Accordingly, in this variation, the UE can instead use parameters such as T-RNTI and RA-RNTI to add to the corresponding sequence of CSI-RS (or SRS or PRS).

[0120] Therefore, by adopting this implementation scheme, the sensing initiator actively carries self-identification information in the transmitted sensing signal. This allows the first device to accurately identify the sensing initiator (which can be a UE or a network device) as the interference source when the sensing signal interferes with external systems (e.g., the first device). Furthermore, the first device can report the acquired identity information (i.e., identification information) of the sensing initiator to the SF network element, so that the SF network element can accurately determine the interference source and then execute the corresponding interference suppression strategy. Thus, enhanced interference identification in the sensing scenario can be achieved.
