[0001] This application relates to the field of communication technology, specifically to a signal transmission method, apparatus, device, chip, and storage medium. Background Technology

[0002] Currently, some sensing signals (such as those used in tracking or speed measurement services) need to be transmitted periodically, inevitably leading to conflicts with communication signals. When sensing and communication signals conflict, the receiving end can typically only receive and process one of the signals, or the transmitting end can only transmit one of the signals. However, there is currently no solution that reveals how to determine which signal to receive and process or which signal to transmit when sensing and communication signals conflict. Summary of the Invention

[0005] Secondly, embodiments of this application provide a signal transmission device applied to a first node. The device includes a communication unit configured to receive and process a first signal or transmit a first signal; wherein the first signal is a signal with higher priority among a communication signal and a sensing signal.

[0019] Figure 1 is a schematic diagram of an application scenario of an embodiment of this application.

[0020] As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0021] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), 6G communication system, or future communication systems, etc.

[0022] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110.

[0027] The communication system 100 may further include a core network device 130 that communicates with the network device 120. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). In some embodiments, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0028] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

Optionally, the communication system 100 may include multiple network devices, and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0032] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0033] 1. Integrated communication and sensing

[0034] Next-generation networks (such as 6G networks) are expected to be a fusion of mobile communication networks, sensing networks, and computing networks. In a narrow sense, a sensing network refers to a system with capabilities such as target localization (ranging, velocity, angle measurement), target imaging, target detection, target tracking, and target recognition. In a broad sense, it refers to a system that encompasses all the attributes and states of services, networks, users, terminals, and environmental objects. From the perspective of sensing applications, they can be divided into the following two categories:

[0035] 1) Outdoor / Wide Area / Local Area Applications: including smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map building, road monitoring, intrusion detection), low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management), etc.

[0036] 2) Indoor / Local Area Applications: including smart home and health management (e.g., respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, motion trajectory tracking, etc.), smart factories (e.g., intrusion detection, material detection, object defect detection, etc.).

[0037] It should be understood that the above classification of sensing applications is merely illustrative, and the application areas of sensing are not limited to the examples above.

[0038] Wireless communication and sensing are two major applications of modern radio frequency (RF) technology. Sensing utilizes radio waves to detect parameters of the physical environment to achieve environmental perception such as target localization, action recognition, and imaging. Traditionally, sensing and wireless communication exist independently, and this separate design leads to a waste of wireless spectrum and hardware resources. With the advent of B5G and 6G, communication spectrum is moving towards millimeter waves, terahertz, and visible light communication; in the future, the spectrum of wireless communication will overlap with the spectrum of traditional sensing. Integrated communication and sensing technology merges these two functions. It can utilize the wireless resources of wireless communication to achieve sensing capabilities; it can leverage widely deployed cellular networks to achieve sensing services over larger areas; it can utilize base stations and multiple terminals for joint sensing to achieve higher sensing accuracy; and it can reuse wireless communication hardware modules to achieve sensing functions, reducing costs. In short, integrated communication and sensing technology enables future wireless communication systems to possess sensing capabilities, providing a foundation for the development of future smart transportation, smart cities, smart factories, drones, and other related businesses.

[0039] 2. Perception Mode

[0040] Perception can be categorized into the following eight modes:

[0041] 1) The base station automatically senses data, as shown in Figure 2(a);

[0042] 2) The terminal automatically senses and receives signals, as shown in Figure 2(b);

[0043] 3) Base station cooperative sensing, as shown in Figure 2(c);

[0044] 4) Terminal collaborative perception, as shown in Figure 2(d);

[0045] 5) Base station-terminal collaborative sensing, as shown in Figure 2(e);

[0046] 6) Terminal-base station collaborative sensing, as shown in Figure 2(f);

[0047] 7) The target being sensed is the node that transmits the sensing signal, as shown in Figure (g) of Figure 2;

[0048] 8) The target being sensed is the sensing signal receiving node, as shown in Figure 2(h).

[0049] The nodes that transmit and receive sensing signals can be collectively referred to as sensing nodes. In the eight sensing modes mentioned above, only a single or pair of sensing nodes exist. However, in wireless communication systems, the number of terminal devices (such as mobile phones, Internet of Things (IoT) devices, etc.) is large. When multiple sensing nodes (such as base stations, mobile phones, IoT devices, etc. that can transmit and / or receive sensing signals) exist around a sensed object, the joint participation of multiple sensing nodes can improve the accuracy of sensing and meet more complex sensing service requirements, providing richer sensing services. When multiple sensing nodes exist in the system, a sensing control node (or sensing management node) may exist to control and manage the entire sensing service to improve efficiency. This sensing control node can be a base station, a terminal, or a core network element. An example of multiple sensing nodes participating in sensing is shown in Figure 3.

[0050] The above provides a brief explanation of the relevant technologies / terms involved in this application, which will not be repeated in the following embodiments.

[0051] Currently, some sensing signals (such as those used in tracking or speed measurement services) need to be transmitted periodically, inevitably leading to conflicts with communication signals. When sensing and communication signals conflict, the receiver can typically only receive one of the signals, or the transmitter can only send one of the signals. However, there is currently no solution that reveals how to determine which signal to receive or send when sensing and communication signals conflict.

[0052] In view of this, this application provides a signal transmission method, apparatus, device, chip, and storage medium. In this method, a first node can receive and process a first signal or transmit a first signal, wherein the first signal is a signal with higher priority among communication signals and sensing signals. Thus, in the event of a conflict between the transmission of sensing signals and communication signals, the first node can receive and process or transmit the first signal with higher priority among communication signals and sensing signals, thereby solving the problem of how to determine which signal to receive and process or which signal to transmit when the transmission of sensing signals and communication signals conflicts.

[0053] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0054] Figure 4 is a flowchart illustrating the signal transmission method provided in an embodiment of this application. As shown in Figure 4, the method may include the following steps:

[0055] S401, the first node receives and processes the first signal or sends the first signal; wherein, the first signal is the signal with higher priority among the communication signal and the sensing signal.

[0056] In this embodiment, the first node can be a receiving device or a sending device.

[0057] In the case where the first node is a receiving device, the first node can receive and process (i.e., receive and process) the first signal. For example, the first node can receive and process the first signal from the second node (the transmitting device).

[0058] In some scenarios, receiving and processing the first signal can also be understood as performing further signal processing on the received first signal, rather than simply receiving the radio frequency signal. In some scenarios, the radio frequency end of the first node may receive the energy of multiple signals, but only the first signal is processed.

[0059] When the first node is a transmitting device, the first node can send a first signal. For example, the first node can send a first signal to the second node (the receiving device).

[0060] It should be noted that the "receiving end device" in the embodiments of this application may also be called (or replaced by) "receiving end", "receiver", "receiving node", etc.; the "sending end device" may also be called (or replaced by) "sending end", "transmitter", "sending node", etc.

[0061] It should also be noted that the receiving device in the embodiments of this application can be a terminal device or a network device; the sending device can also be a terminal device or a network device.

[0062] According to the method of this embodiment, the first node can receive and process a first signal or send a first signal, where the first signal is the signal with higher priority among the communication signal and the sensing signal. Thus, in the event of a conflict between the transmission of the sensing signal and the communication signal, the first node can receive and process or send the first signal with higher priority among the communication signal and the sensing signal, thereby solving the problem of how to determine which signal to receive and process or which signal to send when the transmission of the sensing signal and the communication signal conflict.

[0063] In some embodiments, the first signal is the signal with higher priority among the communication signal and the sensing signal. It can also be understood that the first signal is the signal with the highest priority among the communication signal and the sensing signal, or it can be understood that the first signal is the signal with relatively higher priority among the communication signal and the sensing signal.

[0064] In some embodiments, the communication signal may include, but is not limited to, one or more of the following: downlink shared data channel, downlink control channel, downlink measurement signal, uplink shared data channel, uplink control channel, and uplink measurement signal.

[0065] The aforementioned channels also include demodulation reference signals. For example, a downlink shared data channel also includes demodulation reference signals from the downlink shared data channel; similarly, a downlink control channel also includes demodulation reference signals from the downlink control channel.

[0066] In some embodiments, during a first time period, the priority of the sensing signal is higher than that of the communication signal.

[0067] In other words, if a conflict occurs between the transmission of sensing signals and communication signals during the first time period, the first node can either receive and process the sensing signals or send sensing signals. In some scenarios, the first node can stop receiving and processing communication signals or sending communication signals during the first time period.

[0068] In some embodiments, a first time period is configured. For example, the first time period may be configured by a node with sensing control / management capabilities. For ease of description, the node with sensing control / management capabilities will be referred to as a sensing control node below.

[0069] It should be noted that the sensing and control node in the embodiments of this application can be any entity. For example, the sensing and control node can be a network device (such as a base station), a terminal device, or a core network element. In some scenarios, the sensing and control node can be a first node (sending device / receiving device), or it can be another node / device other than the first node.

[0070] In some embodiments, the first time period can be a sensing measurement interval. That is, within the sensing measurement interval, if the transmission of the sensing signal and the communication signal conflicts, the first node can receive and process the sensing signal or send the sensing signal, and stop receiving and processing the communication signal or sending the communication signal.

[0071] Understandably, some sensing services require the joint detection of multiple sensing signals to obtain the sensing result. For example, in speed measurement, the receiver relies on multiple equally spaced sensing signals for speed detection. Thus, if one or more of these equally spaced sensing signals fail to be received, the ranging task can still be executed, but the speed measurement task will fail or require highly complex algorithms. Therefore, prioritizing the transmission of sensing signals in the first time period can avoid situations where sensing signal acquisition is interrupted and sensing results cannot be obtained, even with a relatively low receiver complexity.

[0072] In some embodiments, when the first node is in an idle state (RRC_Idle state) or an inactive state (RRC_inactive state), the priority of the communication signal is higher than the priority of the sensing signal.

[0073] In other words, if the transmission of sensing signals and communication signals conflicts when the first node is in an idle or inactive state, the first node can receive and process the communication signals or send the communication signals.

[0074] For example, when the first node is both a terminal device and a receiving device, if a conflict occurs between the transmission of sensing signals and communication signals while the first node is in an idle or inactive state, the first node can receive communication signals from the second node (such as a network device). This allows for prioritizing the performance and latency of communication services when the first node is in an idle or inactive state.

[0075] In some embodiments, the priority of communication signals and sensing signals is related to the type of communication signals and / or sensing signals.

[0076] In other words, the first node can determine the priority of the communication signal and / or sensing signal based on the type of the communication signal and / or sensing signal, and then determine the first signal to be received, processed or sent.

[0077] In some embodiments, the sensing signal may include a first type of sensing signal and a second type of sensing signal, wherein the first type of sensing signal has a higher priority than the communication signal; and / or, the second type of sensing signal has a lower priority than the communication signal.

[0078] In one example, the priority of the first type of sensing signal is higher than that of the communication signal. In this case, if the transmission of the first type of sensing signal conflicts with that of the communication signal, the first node can either receive and process the first type of sensing signal or send the first type of sensing signal.

[0079] In one example, the priority of the second type of sensing signal is lower than that of the communication signal. In this case, if the transmission of the second type of sensing signal conflicts with that of the communication signal, the first node can either receive and process the communication signal or send the communication signal.

[0080] In one example, the priority of the first type of sensing signal is higher than that of the communication signal, and the priority of the second type of sensing signal is lower than that of the communication signal. That is, the priority order of the first type of sensing signal, the second type of sensing signal, and the communication signal is: first type of sensing signal > communication signal > second type of sensing signal. In this case, if the transmission of one or more of the first type of sensing signal, the second type of sensing signal, and the communication signal conflicts, the first node can either receive and process the signal with the relatively higher priority or send the signal with the relatively higher priority.

[0081] In some embodiments, the communication signals may include a first type of communication signal and a second type of communication signal, wherein the first type of communication signal has a higher priority than the sensing signal; and / or, the second type of communication signal has a lower priority than the sensing signal.

[0082] In one example, the priority of the first type of communication signal is higher than that of the sensing signal. In this case, if the transmission of the first type of communication signal conflicts with that of the sensing signal, the first node can either receive and process the first type of communication signal or send the first type of communication signal.

[0083] In one example, the priority of the second type of communication signal is lower than that of the sensing signal. In this case, if the transmission of the second type of communication signal conflicts with that of the sensing signal, the first node can either receive and process the sensing signal or send the sensing signal.

[0084] In one example, the priority of the first type of communication signal is higher than that of the sensing signal, and the priority of the second type of communication signal is lower than that of the sensing signal. That is, the priority order of the first type of communication signal, the second type of communication signal, and the sensing signal is: first type of communication signal > sensing signal > second type of communication signal. In this case, if the transmission of one or more of the first type of communication signal, the second type of communication signal, and the sensing signal conflicts, the first node can receive and process the signal with the relatively higher priority or send the signal with the relatively higher priority.

[0085] In some embodiments, the communication signals may include a first type of communication signal and a second type of communication signal, and the sensing signals may include a first type of sensing signal and a second type of sensing signal; wherein, the first type of communication signal has a higher priority than the first type of sensing signal; and / or, the first type of sensing signal has a higher priority than the second type of communication signal; and / or, the second type of communication signal has a higher priority than the second type of sensing signal.

[0086] In one example, the priority of the first type of communication signal is higher than that of the first type of sensing signal. In this case, if the transmission of the first type of communication signal conflicts with that of the first type of sensing signal, the first node can either receive and process the first type of communication signal or send the first type of communication signal.

[0087] In one example, the first type of sensing signal has a higher priority than the second type of communication signal. In this case, if the transmission of the first type of sensing signal conflicts with the transmission of the second type of communication signal, the first node can either receive and process the first type of sensing signal or send the first type of sensing signal.

[0088] In one example, the priority of the second type of communication signal is higher than that of the second type of sensing signal. In this case, if the transmission of the second type of communication signal conflicts with that of the second type of sensing signal, the first node can either receive and process the second type of communication signal or send the second type of communication signal.

[0089] In one example, the priority order of the first type of communication signal, the second type of communication signal, the first type of sensing signal, and the second type of sensing signal is: first type of communication signal > first type of sensing signal > second type of communication signal > second type of sensing signal. In this case, if the transmission of one or more of the first type of communication signal, the second type of communication signal, the first type of sensing signal, and the second type of sensing signal conflicts, the first node can receive and process the signal with the relatively higher priority or send the signal with the relatively higher priority.

[0090] In some embodiments, the communication signals may include a first type of communication signal and a second type of communication signal, and the sensing signals may include a first type of sensing signal and a second type of sensing signal; wherein, the first type of sensing signal has a higher priority than the first type of communication signal; and / or, the first type of communication signal has a higher priority than the second type of sensing signal, and / or, the second type of sensing signal has a higher priority than the second type of communication signal.

[0091] In one example, the priority of the first type of sensing signal is higher than that of the first type of communication signal. In this case, if the transmission of the first type of sensing signal conflicts with that of the first type of communication signal, the first node can either receive and process the first type of sensing signal or send the first type of sensing signal.

[0092] In one example, the first type of communication signal has a higher priority than the second type of sensing signal. In this case, if the transmission of the first type of communication signal conflicts with the transmission of the second type of sensing signal, the first node can either receive and process the first type of communication signal or send the first type of communication signal.

[0093] In one example, the priority of the second type of sensing signal is higher than that of the second type of communication signal. In this case, if the transmission of the second type of sensing signal conflicts with that of the second type of communication signal, the first node can either receive and process the second type of sensing signal or send the second type of sensing signal.

[0094] In one example, the priority order of the first type of communication signal, the second type of communication signal, the first type of sensing signal, and the second type of sensing signal is: first type of sensing signal > first type of communication signal > second type of sensing signal > second type of communication signal. In this case, if the transmission of one or more of the first type of communication signal, the second type of communication signal, the first type of sensing signal, and the second type of sensing signal conflicts, the first node can receive and process the signal with the relatively higher priority or send the signal with the relatively higher priority.

[0095] In some embodiments, the communication signal may include a third type of communication signal; the third type of communication signal is the highest priority signal among the communication signals and sensing signals. That is, if the transmission of the third type of communication signal conflicts with the transmission of sensing signals and / or other types of communication signals, the first node may receive, process, or transmit the third type of communication signal.

[0096] As an example, the third type of communication signal may include broadcast signals and / or synchronization signals. Since broadcast signals and synchronization signals affect the access and mobility management of all users within the cell, prioritizing the transmission of broadcast signals and synchronization signals can avoid impacting the access and mobility management of users within the cell.

[0097] According to the method of this embodiment, the first node determines the transmission priority based on the type of sensing signal and / or communication signal, which enables the system to operate more efficiently and is beneficial to meeting the signal transmission needs of different types of communication services and / or sensing services.

[0098] In some embodiments, the scheme by which the first node determines transmission priority based on the type of the sensing signal and / or communication signal is applicable when the processing methods of the sensing signal and communication signal are common. For example, the sensing signal and communication signal have the same waveform (e.g., both use Orthogonal Frequency Division Multiplexing (OFDM)), and / or the sensing signal and communication signal are configured with the same parameters (e.g., the same Sub-Carrier Space (SCS) and / or Cyclic Prefix (CP)). In this way, the first node does not need to use different processing modes for the communication signal and the sensing signal, that is, it does not need to switch between the mode for processing the sensing signal and the mode for processing the communication signal.

[0099] In some embodiments, the scheme by which the first node determines the transmission priority based on the type of the sensing signal and / or communication signal can also be used when the processing methods for the sensing signal and the communication signal are drastically different. In this case, sufficient time needs to be reserved for switching, so that the first node has enough time to switch from the mode of processing sensing signals to the mode of processing communication signals, or vice versa.

[0100] In some embodiments, the priority of at least some of the communication signals and sensing signals is configured.

[0101] For example, the sensing control node can assign a priority to at least a portion of the communication signals and sensing signals to the first node, so that the first node can determine the first signal to be received, processed, or transmitted based on the assigned priority.

[0102] In some embodiments, the priority of the sensing signals in at least a portion of the signals is configured for the frequency layer, or for the set of sensing signal resources, or for the sensing signal resources themselves.

[0103] As an example, in at least a portion of the signal, the priority of the sensing signal is configured for a frequency layer. That is, sensing signals transmitted on the same frequency layer can be configured with the same priority; sensing signals transmitted on different frequency layers can be configured with different priorities, or they can be configured with the same priority. The sensing signals transmitted on a particular frequency layer can be sensing signals mapped to the same frequency band but originating from different transmitting nodes.

[0104] As an example, in at least a portion of the signals, the priority of the sensing signals is configured for a set of sensing signal resources. That is, sensing signals transmitted on the same set of sensing signal resources can be configured with the same priority; sensing signals transmitted on different sets of sensing signal resources can be configured with different priorities, or they can be configured with the same priority. Sensing signals transmitted on a particular set of sensing signal resources can originate from the same transmitting node. Typically, a transmitting node can configure one or more sets of sensing signal resources.

[0105] In one example, the priority of the sensing signals in at least a portion of the signals is configured for sensing signal resources. That is, sensing signals transmitted on the same sensing signal resource can be configured with the same priority; sensing signals transmitted on different sensing signal resources can be configured with different priorities, or they can be configured with the same priority. Here, a sensing signal resource can, for example, refer to a set of sensing signal resource units. Typically, a set of sensing signal resources may contain one or more sensing signal resources.

[0106] In some embodiments, the priority of the communication signals in at least a portion of the signals is configured via semi-static configuration signaling and / or dynamic configuration signaling.

[0107] As an example, the priority of a communication signal with a semi-static / semi-persistent configuration can be configured in the corresponding semi-static configuration signaling. For instance, for a downlink semi-persistent signal (such as a semi-persistent scheduling (SPS) signal), the priority of the signal can be configured in the SPS configuration (such as SPS-config); as another example, for a communication signal transmitted on a configured grant resource, the priority of the communication signal can be configured in the configured grant (CG) configuration (such as ConfiguredGrantConfig).

[0108] As an example, for dynamically configured communication signals, priority can be configured via dynamic configuration signaling. For instance, a priority information field can be included in the downlink grant (DL grant) / uplink grant (UL grant) to indicate the priority of the communication signal.

[0109] In some embodiments, there is no conflict in the transmission resources of sensing signals and communication signals configured with the same priority among at least a portion of the signals. That is, when sensing signals and communication signals are configured with the same priority, there is no conflict in the transmission resources of the sensing signals and the communication signals.

[0110] In some embodiments, the priority of sensing signals and communication signals configured with the same priority among at least a portion of the signals can be determined based on a configured first parameter or a predefined first rule. That is, when sensing signals and communication signals are configured with the same priority, the priorities of the sensing signals and the communication signals can be further distinguished based on the configured first parameter or a predefined first rule.

[0111] As an example, when sensing signals and communication signals are configured with the same priority, their priorities can be further distinguished based on a first configured parameter. For instance, if the first parameter is value #1 (e.g., "Type 1"), the sensing signal has a higher priority; if the first parameter is value #2 (e.g., "Type 2"), the communication signal has a higher priority. This first parameter can be configured, for example, by the sensing control node.

[0112] As an example, when sensing signals and communication signals are configured with the same priority, the priorities of sensing signals and communication signals can be further distinguished based on a predefined (such as a protocol definition) first rule. For example, the first rule could be: sensing signals have higher priority, or communication signals have higher priority.

[0113] In some embodiments, among the communication signals and sensing signals, there is at least one signal without a configured priority; this signal without a configured priority has the lowest priority. That is, for the communication signals and sensing signals without a configured priority, they can be defaulted to low priority.

[0114] According to the method of this embodiment, the priority of communication signals and / or sensing signals (such as partial communication signals and / or partial sensing signals) can be configured. Therefore, the priority of sensing signals and / or communication signals can be flexibly configured by taking into account various factors (such as whether transmission interruption is allowed, the timeliness of the service (ordinary service / low latency service), the capability of the first node, etc.).

[0115] In some embodiments, the priorities of communication signals and sensing signals may be determined based on a configured second parameter.

[0116] For example, the sensing control node can configure the second parameter to the first node, so that the first node can determine the priority of the communication signal and the sensing signal according to the configured second parameter, and then determine the first signal to be received, processed or sent.

[0117] In some embodiments, different values ​​of the second parameter may correspond to different priority orders, including priority orders for communication signals and sensing signals.

[0118] For example, if the second parameter is set to the first value (e.g., "processing type 1"), the corresponding priority order is priority order #1. The first node can then determine the priority of the communication signal and the sensing signal based on priority order #1. Similarly, if the second parameter is set to the second value (e.g., "processing type 2"), the corresponding priority order is priority order #2. The first node can then determine the priority of the communication signal and the sensing signal based on priority order #2. Furthermore, in the event of a conflict between the transmission of the communication signal and the sensing signal, the first node can receive, process, or transmit the first signal with the relatively higher priority among the communication signal and the sensing signal.

[0119] In some embodiments, priority ordering may include one or more of the following A) to L):

[0120] A) Sensing signals have a higher priority than communication signals;

[0121] B) Communication signals have a higher priority than sensing signals;

[0122] C) The priority of the first type of sensing signal is higher than that of the communication signal;

[0123] D) The priority of the second type of sensing signal is lower than that of the communication signal;

[0124] E) The priority of the first type of communication signal is higher than that of the sensing signal;

[0125] F) The priority of the second type of communication signal is lower than that of the sensing signal;

[0126] G) The priority of the first type of communication signal is higher than the priority of the first type of sensing signal;

[0127] H) The priority of the first type of sensing signal is higher than the priority of the second type of communication signal;

[0128] I) The priority of the second type of communication signal is higher than the priority of the second type of sensing signal;

[0129] J) The priority of the first type of sensing signal is higher than the priority of the first type of communication signal;

[0130] K) The priority of the first type of communication signal is higher than the priority of the second type of sensing signal;

[0131] L) The priority of the second type of sensing signal is higher than that of the second type of communication signal.

[0132] Among them, the first type of sensing signal and / or the second type of sensing signal are included in the sensing signal; the first type of communication signal and / or the second type of communication signal are included in the communication signal.

[0133] For example, priority ordering may include A), then the priority ordering of communication signals and sensing signals is: priority of sensing signals > priority of communication signals.

[0134] In another example, the priority ordering may include C) and D), then the priority ordering of communication signals and sensing signals would be: first type of sensing signals > communication signals > second type of sensing signals.

[0135] Another example is that the priority order can include G), H), and I). In this case, the priority order of communication signals and sensing signals would be: first type of communication signal > first type of sensing signal > second type of communication signal > second type of sensing signal.

[0136] It should be understood that priority ordering can also include other cases, which will not be listed here.

[0137] According to the method of this embodiment, different priority orders can be configured by setting different values ​​for the second parameter. Therefore, the value of the second parameter can be flexibly configured by taking into account various factors (such as whether transmission interruption is allowed, the timeliness of the service (normal service / low latency service), the capability of the first node, etc.), thereby flexibly realizing different priority orders.

[0138] In some embodiments, the first type of sensing signal may include one or more of the following signals: periodically transmitted sensing signals; equally spaced sensing signals; sensing signals related to speed sensing; sensing signals related to micro-motion sensing; and high-priority sensing signals.

[0139] For example, the sensing signals associated with speed measurement sensing may include one or more of the following: sensing signals for speed measurement tasks; sensing signals for speed measurement tasks that can also be used for other sensing tasks (e.g., sensing signals for speed and distance measurement); and sensing signals for other tasks whose sensing results depend on the speed measurement results (e.g., sensing signals for speed-based target detection, sensing signals for clutter suppression, etc.).

[0140] For example, the sensing signals related to micro-motion sensing may include one or more of the following: sensing signals for micro-motion sensing tasks (e.g., sensing tasks for detecting the rotation of UAV rotors, sensing tasks for detecting breathing and heartbeat, etc.); sensing signals for micro-motion sensing tasks that can also be used for other sensing tasks; and sensing signals for other tasks whose sensing results depend on the micro-motion sensing results (e.g., sensing signals for micro-Doppler-based target recognition, sensing signals for clutter suppression, etc.).

[0141] In some embodiments, the second type of sensing signal may include: sensing signals other than the first type of sensing signal; and / or, low-priority sensing signals.

[0142] In some embodiments, whether a sensing signal belongs to a first type of sensing signal, and / or whether a sensing signal belongs to a second type of sensing signal, can be determined based on the configuration associated with the sensing signal.

[0143] For example, in the configuration of the sensing signal corresponding to the sensing signal, the transmission time of the sensing signal can be configured, so that it can be determined whether the sensing signal is a periodically transmitted sensing signal, and / or whether it is a sensing signal transmitted at equal intervals, based on the transmission time of the sensing signal.

[0144] For example, in the sensing and reporting configuration corresponding to the sensing signal, the information that the receiver needs to report can be configured. If the information that needs to be reported includes at least one of "speed", "mode", "Doppler", and "micro-Doppler", or if the information that needs to be reported includes information that can only be obtained based on at least one of "speed", "mode", "Doppler", and "micro-Doppler", then it can be determined that the sensing signal is a sensing signal related to speed sensing, and / or a sensing signal related to micro-motion sensing.

[0145] For example, in the configuration related to sensing signals, it is also possible to configure whether the sensing signal is a high-priority / low-priority sensing signal.

[0146] As one possible implementation, the configuration related to the sensing signal can be configured by the sensing control node.

[0147] It is understandable that the sensing tasks corresponding to the first type of sensing signals (such as speed measurement tasks) typically rely on multiple equally spaced sensing signals. Therefore, if one or more of these equally spaced sensing signals cannot be received normally, the sensing task may fail to execute properly. Thus, in this embodiment, by ensuring that the first type of sensing signals have a relatively high priority (e.g., the priority of the first type of sensing signals is higher than that of communication signals), the consequence of all related sensing signal processing becoming ineffective due to the failure of one sensing signal to be received normally during the execution of this type of sensing task can be avoided.

[0148] Correspondingly, the sensing tasks corresponding to the second type of sensing signals (such as ranging tasks) usually do not need to rely on multiple equally spaced sensing signals. Therefore, the priority of the second type of sensing signals can be relatively low (for example, the priority of the second type of sensing signals can be lower than the priority of communication signals), which is conducive to ensuring the transmission reliability and low latency of communication services.

[0149] In some embodiments, the first type of communication signal may include: cell-specific communication signals; and / or, high-priority communication signals.

[0150] In some embodiments, the second type of communication signal may include: terminal device-specific communication signals; and / or, low-priority communication signals.

[0151] In some embodiments, whether a communication signal belongs to a first type of communication signal, and / or whether a communication signal belongs to a second type of communication signal, can be determined based on the configuration associated with the communication signal.

[0152] As one possible implementation, the configuration related to the communication signal can be configured by the network device. Thus, based on the configuration related to the communication signal, the first node can determine whether the communication signal is a cell-specific signal or a terminal device-specific signal, and / or whether the communication signal is a high-priority signal or a low-priority signal.

[0153] It is understood that the first type of communication signal usually has high requirements for transmission latency (e.g., low latency transmission is required). Therefore, in this embodiment of the application, by ensuring that the first type of communication signal has a relatively high priority (e.g., the priority of the first type of communication signal is higher than the priority of the sensing signal), it is beneficial to prioritize the low latency transmission.

[0154] In some embodiments, the symbol occupied by the sensing signal does not conflict with the symbol occupied by the second signal. In other words, it is not expected that the sensing signal will map to the symbol occupied by the second signal.

[0155] For example, the second signal may include one or more of the following signals: a broadcast signal; a synchronization signal; and an initial access signal.

[0156] It is understandable that secondary signals (such as broadcast signals, synchronization signals, and initial access signals) can affect the access and mobility management of all users in the entire cell. Therefore, ensuring that the symbols occupied by the sensing signals do not conflict with the symbols occupied by the secondary signals is beneficial to avoid affecting the access and mobility management of users in the cell.

[0157] In some embodiments, the priority of communication signals and sensing signals is related to the capabilities of the first node.

[0158] For example, if the first node (as the receiver) does not support non-uniform sensing signal processing capabilities, or in other words, if the first node does not support processing non-equally spaced sensing signals, then the first node cannot support situations where communication signals have high priority. In other words, even if the transmission of sensing signals and communication signals conflicts, the first node can still receive the sensing signals. This helps avoid situations where the originally equally spaced sensing signals become unequally spaced due to the inability to receive a single sensing signal, thus preventing the first node from receiving sensing signals that cannot be processed properly.

[0159] In some embodiments, for a first node that does not support non-uniform sensing signal processing capabilities, if the priority of the communication signal is higher than the priority of the sensing signal, the corresponding sensing report may be reported as invalid when the sensing signal is discarded.

[0160] In some embodiments, the first node (as the receiver) may report its capabilities (such as not supporting non-uniform sensing signal processing capabilities) to the sensing control node. Thus, the sensing control node may configure the priority of communication signals and sensing signals according to the capabilities of the first node, or configure corresponding second parameters according to the capabilities of the first node, so as to avoid the situation where the capabilities of the first node are not supported during signal transmission.

[0161] In some embodiments, if the first node does not support conflict resolution capabilities, the first node does not expect the sensing signal to be mapped to the symbol where the communication signal is located.

[0162] In some embodiments, the first node receiving and processing the first signal or sending the first signal includes: in the event of a conflict between the transmission resources of the communication signal and the sensing signal (or, in the event of a conflict between the transmission of the communication signal and the sensing signal), the first node receiving and processing the first signal or sending the first signal.

[0163] In other words, when there is a conflict between the transmission of sensing signals and communication signals, the first node can receive, process, or send the first signal with higher priority among the communication signals and sensing signals.

[0164] It should be noted that in some scenarios, the first node can determine / judge the priority order of communication signals and sensing signals, and thus determine the first signal to be received, processed, or transmitted based on the priority order. In other scenarios, the first node may not determine / judge the priority order of communication signals and sensing signals, but instead directly determine the first signal to be received, processed, or transmitted according to rules. For example, the first node may determine the first signal to be received, processed, or transmitted according to a protocol agreement.

[0165] According to the method of this embodiment, when the transmission of sensing signals and communication signals conflicts, the first node can receive, process, or send the first signal with higher priority among the communication signals and sensing signals, thereby solving the problem of how to determine which signal to receive and process or which signal to send when the transmission of sensing signals and communication signals conflicts.

[0166] The signal transmission method provided in the embodiments of this application has been described above. To facilitate understanding of the embodiments of this application, possible implementation schemes of the signal transmission method applicable to the embodiments of this application are described below.

[0167] The following describes four implementation schemes provided in the embodiments of this application (denoted as Scheme 1, Scheme 2, Scheme 3 and Scheme 4).

[0168] Option 1

[0169] In Option 1, it is not expected that the sensed signal will be mapped to the symbol of the second signal. In other words, there is no conflict between the symbols of the sensed signal and the second signal. One possible approach is to agree, through a protocol, that the sensed signal and the second signal are mapped to different symbols.

[0170] For example, the second signal may include one or more of the following signals: broadcast signal, synchronization signal, initial access signal.

[0171] It is understandable that the second signal (such as broadcast signal, synchronization signal, initial access signal) will affect the access and mobility management of all users in the entire cell. Therefore, mapping the sensing signal and the second signal to different symbols is beneficial to avoid affecting the access and mobility management of users in the cell.

[0172] The following schemes two through four are mainly used to resolve the conflict between sensing signals and communication signals.

[0173] For example, the communication signal may include, but is not limited to, one or more of the following: downlink shared data channel, downlink control channel, downlink measurement signal, uplink shared data channel, uplink control channel, and uplink measurement signal.

[0174] It should be noted that the aforementioned channels also include demodulation reference signals. For example, the downlink shared data channel also includes demodulation reference signals from the downlink shared data channel; similarly, the downlink control channel also includes demodulation reference signals from the downlink control channel.

[0175] Option 2

[0176] In Scheme 2, sensing signals have a high priority, while communication signals have a low priority.

[0177] In some embodiments, Scheme 2 can be used within the sensing and measurement interval. Within this interval, the receiver can complete the reception and measurement of sensing signals and stop receiving communication signals. That is, within the sensing and measurement interval, all sensing signals are high-priority signals, and all communication signals are low-priority signals.

[0178] In some embodiments, the sensing measurement range can be configured. For example, the sensing measurement range can be configured by the sensing control node.

[0179] Understandably, speed measurement requires the joint detection of multiple sensing signals to obtain the sensing result. Furthermore, for most receivers, speed detection relies on equally spaced sensing signals. Therefore, if one or more of the equally spaced sensing signals cannot be received normally, ranging can be performed normally, but speed measurement will fail or require highly complex algorithms. Therefore, adopting a scheme that prioritizes the transmission of sensing signals can avoid situations where sensing information acquisition is interrupted and sensing results cannot be obtained, even with a relatively low receiver complexity.

[0180] Furthermore, for target detection services, especially those relying on speed for target recognition, the receiver will also perform speed measurement. Therefore, for sensing tasks that do not directly rely on equally spaced sensing signals (or, in other words, sensing tasks that indirectly rely on equally spaced sensing signals), it is also necessary to prioritize the transmission of sensing signals.

[0181] Furthermore, considering that the sensing signal uses a larger bandwidth, typically greater than the bandwidth of a user's communication signal, a sensing signal may conflict with the communication signals of multiple users. A user cannot know whether the sensing signal conflicts with other users. Therefore, adopting a scheme that prioritizes the transmission of the sensing signal ensures consistent receiver behavior and signal interpretation in any conflict situation (known conflict, e.g., conflict between its own communication signal and the sensing signal; unknown conflict, e.g., conflict between another user's communication signal and the sensing signal), meaning the received signal is always the sensing signal.

[0182] Furthermore, sensing signals and communication signals are generated in different ways, and the transceiver processing for sensing and communication cannot be shared; they must be completed independently. For example, sensing signals may use pulsed or frequency-modulated continuous waves, while communication signals may use OFDM. Alternatively, sensing and communication signals may use different subcarrier spacings (SCS) and / or cyclic prefix lengths (CP). In such cases, the receiver can only choose one of the two signals, meaning it can only receive one of the sensing or communication signals.

[0183] Option 3

[0184] In Scheme 3, communication signals have a high priority, while sensing signals have a low priority.

[0185] In some embodiments, Scheme 3 can be used when the receiver is in an idle state (e.g., RRC_Idle state) or a power-saving state (e.g., RRC_inactive state). For example, when the receiver is in an idle or power-saving state, it can receive only the communication signal that keeps the connection open. This is advantageous in prioritizing the performance and latency of the communication service when the receiver is in an idle or power-saving state.

[0186] Option 4

[0187] In Scheme 4, some sensing signals are transmitted with priority. For example, the transmission priority can be determined by combining the type of sensing signal and / or the type of communication signal.

[0188] Understandably, receiver processing differs for different sensing tasks. For example, ranging typically relies on a single sensing signal to obtain the result; speed measurement requires the joint detection of multiple sensing signals. Furthermore, for most receivers, speed measurement relies on equally spaced sensing signals. Therefore, if one or more of the equally spaced sensing signals fail to be received, ranging can proceed normally, but speed measurement will fail or require highly complex algorithms. In addition, many optimized algorithms smooth multiple sensing results; a single erroneous sensing result will affect the accuracy of multiple results. In other words, a single erroneous sensing result from non-equally spaced detection can impact numerous other sensing results. Therefore, the impact of canceling the transmission of one sensing signal varies depending on the specific sensing task.

[0189] Furthermore, the timeliness requirements vary across different services. For example, Ultra-Reliable Low-Latency Communication (URLLC) is latency-sensitive, requiring accurate transmission within a short timeframe; specifically, a 99.999% accuracy rate is needed within 1ms. In contrast, Enhanced Mobile Broadband (eMBB) has less stringent latency requirements, requiring a 90% accuracy rate within 4ms. Similarly, vehicle speed measurement is latency-sensitive and needs to be completed within a short timeframe, such as within 1 second. Pedestrian speed measurement has less stringent latency requirements, such as within 5 seconds. For latency-sensitive services, immediate and accurate transmission / sensing is necessary; for latency-insensitive services, even if a transmission / sensing error occurs or an opportunity is missed, subsequent transmission / sensing can still meet the service requirements.

[0190] In summary, determining transmission priority by combining the type of sensing signal and / or the type of communication signal enables the system to operate more efficiently and meet the performance requirements of the business.

[0191] In some embodiments, Scheme 4 can be used when the processing methods of the sensing signal and the communication signal are similar. For example, the waveforms of the sensing signal and the communication signal are the same (e.g., both use OFDM), and / or the sensing signal and the communication signal are configured with the same parameters (e.g., the same SCS and / or CP). In this way, the receiver can first perform radio frequency processing and analog-to-digital conversion on the received signal to convert the signal to the frequency domain. Then, for the frequency domain signal, the receiver can extract and process the sensing signal and / or the communication signal.

[0192] In some embodiments, Scheme 4 can also be used when the processing methods for sensing signals and communication signals are drastically different. In this case, sufficient time needs to be reserved for switching, allowing the receiving end enough time to switch from the mode of processing sensing signals to the mode of processing communication signals, or vice versa.

[0193] Implementation method 1 of scheme 4: Determine the priority of signal transmission based on the type of sensing signal.

[0194] As an example, in cases where sensing results are obtained based on equally spaced sensing signals, the sensing signals have high priority; that is, sensing signals are received, and communication signals are canceled / discarded. For example, sensing signal types used for speed measurement (speed measurement only; including speed measurement, such as speed-distance measurement, speed-based target detection, etc.) and / or micro-motion sensing (such as UAV rotor rotation sensing, breathing and heartbeat sensing, etc.) are transmitted first.

[0195] As an example, in cases where a sensing result can be obtained based on a single sensing signal, the communication signal has high priority; that is, the communication signal is received, and the sensing signal is canceled / discarded. For instance, in the event of a conflict between sensing signal types used for ranging / angle measurement, transmission is canceled.

[0196] For the above scheme, the sensing signal receiver can determine the priority of signal transmission based on the sensing signal type.

[0197] For example, the sensing signal receiver can determine whether the sensing signal is a periodic signal, or whether it is an equally spaced signal, or whether it is a signal related to speed measurement and / or micro-motion sensing. If it is, the sensing signal is transmitted first; otherwise, the communication signal is transmitted first.

[0198] In some embodiments, whether a signal is periodic or equally spaced can be determined based on the sensing signal configuration; whether it is a signal related to speed measurement and / or micro-motion sensing can be determined based on the sensing reporting configuration corresponding to the sensing signal. For example, if the sensing reporting configuration includes parameters related to "speed," "mode," or "Doppler" (or in other words, the sensing reporting configuration instructs the receiver to report information related to "speed," "mode," or "Doppler"), then the sensing signal corresponding to that sensing reporting configuration can be transmitted with priority.

[0199] According to the method of this embodiment, for detection methods that require multiple sets / multiple equally spaced sensing signals, the corresponding sensing signals have high priority, thereby avoiding the consequence that all related sensing signal processing becomes invalid due to a single sensing signal conflict. For detection methods that rely on only one set / one sensing signal, the corresponding sensing signal has low priority, thereby ensuring the transmission reliability and low latency of communication services.

[0200] Implementation method 2 of scheme 4: Determine the priority of signal transmission based on the type of communication signal.

[0201] For example, cell-specific communication signals have high priority, while user-specific communication signals have low priority. That is, when cell-specific communication signals conflict with sensing signals, cell-specific communication signals are transmitted; when user-specific communication signals conflict with sensing signals, sensing signals are transmitted.

[0202] For example, higher priority communication signals have higher priority, and lower priority communication signals have lower priority. That is, when a higher priority communication signal conflicts with a sensing signal, the higher priority communication signal is transmitted; when a lower priority communication signal conflicts with a sensing signal, the sensing signal is transmitted.

[0203] According to the method of this embodiment, communication signals with high latency requirements (such as low latency requirements) can be transmitted first, which is beneficial to prioritize the transmission of low latency signals.

[0204] Implementation method 3 of scheme 4: Determine the priority of signal transmission based on the type of communication signal and the type of sensing signal.

[0205] For example, priority is given to first-class communication signals, which in turn takes precedence over first-class sensing signals, which takes precedence over second-class communication signals, which takes precedence over second-class sensing signals. For instance, the priority order could be: broadcast signals / synchronization signals > speed-measuring sensing signals > other communication signals besides broadcast / synchronization signals > positioning sensing signals. Another example could be: high-priority communication signals > speed-measuring sensing signals > low-priority communication signals > positioning sensing signals.

[0206] As an example, Category 3 communication signals take precedence over all sensing signals and / or communication signal types; Category 1 sensing signals / Category 1 communication signals take precedence over Category 2 sensing signals / Category 2 communication signals. For instance, the priority order is: broadcast signals / synchronization signals > high-priority sensing signals / high-priority communication signals > low-priority sensing signals / low-priority communication signals.

[0207] The method of this embodiment, by comprehensively considering the types of communication signals and sensing signals, can make the overall efficiency of the integrated sensing system higher.

[0208] Implementation method 4 of scheme 4: Determine the priority of signal transmission based on the configured priority.

[0209] In some embodiments, priorities can be configured for sensing signals and / or communication signals respectively. For sensing signals and / or communication signals without configured priorities (especially user-specific signals, such as at least one of PDSCH, PDCCH, PUSCH, PUCCH, CSI-RS, and SRS), they are assigned low priority by default.

[0210] In some embodiments, the priority of sensing signals and / or communication signals can be configured by the sensing control node.

[0211] In some embodiments, the priority configuration of sensing signals can be configured at a frequency layer, a set of sensing signal resources, or sensing signal resources. Sensing signals transmitted on a frequency layer can be sensing signals mapped to the same frequency band but originating from different transmitting nodes. Sensing signals transmitted on a set of sensing signal resources can be sensing signals originating from the same transmitting node. Typically, a transmitting node can be configured with one or more sets of sensing signal resources. A sensing signal resource can, for example, refer to a group of sensing signal resource elements. Typically, a set of sensing signal resources can contain one or more sensing signal resources.

[0212] In some embodiments, the priority of a semi-static / semi-persistent communication signal can be configured in the corresponding semi-static configuration signaling. For example, for a downlink semi-persistent signal (SPS), the priority of the signal can be configured in the SPS configuration (e.g., SPS-config); as another example, for a communication signal transmitted on a configured grant, the priority of the communication signal can be configured in the CG configuration (e.g., ConfiguredGrantConfig). For dynamically configured communication signals, the priority can be indicated by dynamic scheduling signaling. For example, a priority information field can be included in the downlink grant (DL grant) / uplink grant (UL grant).

[0213] In some embodiments, it is not expected that the sensing signal will be configured on a communication signal with the same priority. In other words, if the sensing signal and the communication signal are configured with the same priority, there is no conflict in the transmission resources of the sensing signal and the communication signal.

[0214] In some embodiments, where the sensing signals and communication signals are configured with the same priority, the priorities of the sensing signals and communication signals can be further distinguished.

[0215] As an example, when sensing signals and communication signals are configured with the same priority, their priorities can be further differentiated based on the sensing signal processing type. For instance, for type 1, sensing signals have a higher priority; for type 2, communication signals have a higher priority. The sensing signal processing type can, for example, be configured by the sensing control node.

[0216] As an example, when sensing signals and communication signals are configured with the same priority, their priorities can be further differentiated based on protocol conventions. For instance, the protocol could specify that sensing signals have a higher priority, or communication signals have a higher priority.

[0217] According to the method of this embodiment, the sensing control node can flexibly configure the priority of sensing signals and / or communication signals by taking into account various factors (such as whether interruption is allowed, the timeliness of services (normal services / low-latency services), terminal capabilities, etc.).

[0218] Implementation method 5 of scheme 4: Determine the priority of signal transmission based on the configured processing type.

[0219] In some embodiments, the processing type can be configured by the sensing control node, and different processing types can correspond to different priority orders.

[0220] In some embodiments, the receiver / transmitter can be configured with a processing type. If the configured processing type is processing type 1, the sensing signal has a high priority and the communication signal has a low priority; if the configured processing type is processing type 2, the high-priority communication signal has a higher priority than the sensing signal, and the sensing signal has a higher priority than the low-priority communication signal; if the configured processing type is processing type 3, the communication signal has a high priority and the sensing signal has a low priority.

[0221] In some embodiments, the receiver / transmitter can be configured with a processing type. If the configured processing type is processing type 1, the sensing signal has a high priority and the communication signal has a low priority; if the configured processing type is processing type 2, the high-priority communication signal has a higher priority than the first type of sensing signal, the first type of sensing signal has a higher priority than the low-priority communication signal, and the low-priority communication signal has a higher priority than the second type of sensing signal; if the configured processing type is processing type 3, the communication signal has a high priority and the sensing signal has a low priority.

[0222] In some embodiments, the receiver / transmitter can be configured with a processing type. If the configured processing type is processing type 1, the sensing signal has a high priority and the communication signal has a low priority; if the configured processing type is processing type 2, the high-priority communication signal has a higher priority than the first type of sensing signal, the first type of sensing signal has a higher priority than the low-priority communication signal, and the low-priority communication signal has a higher priority than the second type of sensing signal; if the configured processing type is processing type 3, the high-priority communication signal has a higher priority than the sensing signal, and the sensing signal has a higher priority than the low-priority communication signal; if the configured processing type is processing type 4, the communication signal has a high priority and the sensing signal has a low priority.

[0223] In some embodiments, the receiver / transmitter can be configured with a processing type. If the configured processing type is processing type 1, the sensing signal has a high priority and the communication signal has a low priority; if the configured processing type is processing type 2, the first type of sensing signal has a higher priority than the high-priority communication signal, the high-priority communication signal has a higher priority than the second type of sensing signal, and the second type of sensing signal has a higher priority than the low-priority communication signal; if the configured processing type is processing type 3, the first type of sensing signal has a higher priority than the communication signal, and the communication signal has a higher priority than the second type of sensing signal; if the configured processing type is processing type 4, the communication signal has a high priority and the sensing signal has a low priority.

[0224] In some embodiments, the type of sensing signal can be determined by direct or indirect configuration, as described in the relevant description in Implementation 1 of Scheme 4, which will not be repeated here.

[0225] According to the method of this embodiment, the sensing and control node can flexibly configure the processing type by comprehensively considering various factors (such as whether interruption is allowed, the timeliness of the service (normal service / low latency service), terminal capabilities, etc.), thereby flexibly realizing different priority sorting.

[0226] It should be noted that the various implementation methods of Scheme 4 (Implementation Method 1 to Implementation Method 5) are not mutually exclusive, or in other words, multiple implementation methods can be used within a single system.

[0227] In some embodiments, the method used by the receiver for signal transmission is related to the receiver's capability reporting.

[0228] As an example, for a receiver that does not support conflict resolution capabilities, the receiver does not expect to perceive signals mapped to the symbols on which the communication signals are located.

[0229] For example, a receiver that does not support first sensing signal processing capabilities (e.g., does not support non-uniform sensing signal processing capabilities) may not support situations where communication signals have high priority. Alternatively, if the communication signal priority is higher than the sensing signal priority, and the sensing signal is discarded, the corresponding sensing report may be invalid.

[0230] According to the method of this application embodiment, a first node (receiving end or sending end) can receive, process, or send the signal with higher priority among communication signals and sensing signals. The first node can determine the priority based on at least one of the following conditions: protocol agreement; communication signal type; sensing signal type; priority configuration; processing type. The method of this application embodiment solves the problem of how to determine which signal to receive / process or which signal to send when sensing signals and communication signals conflict.

[0231] It should be noted that the term "perception" in the embodiments of this application can also be replaced by any term that can represent the meaning of perception, such as positioning, ranging, velocity measurement, angle measurement, target imaging, target detection, target tracking, target recognition, etc.
