[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used not only in the systems and radio technologies mentioned above, but also in other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in most of the following description; however, these technologies can also be applied to applications beyond NR systems, such as 6th Generation (6G) communication systems.

[0034] This application provides a method for signal transmission in a communication and sensing integrated scenario, which solves the problem of the transmitting end device notifying the receiving end device of the signal type, time-frequency / spatial resources, sequence format, waveform and other information of the transmitted signal (sent by the transmitting end device), so that the receiving end device can distinguish and process communication signals, sensing signals and communication and sensing integrated signals, thereby improving the efficiency of the receiving end device in processing signals and reducing the processing complexity.

[0035] Integrated Communication and Sensing System: This design integrates communication and sensing functions within the same system through spectrum sharing and / or hardware sharing. While transmitting signals, the integrated communication and sensing system can sense information such as location, distance, and speed to detect, track, and identify objects, environments, or events. In this system, the communication and sensing systems complement each other, saving costs, reducing system size, lowering power consumption, improving spectrum efficiency, and reducing mutual interference, thereby enhancing overall system performance.

[0036] The feasibility of the integrated communication and sensing system is mainly reflected in the following aspects:

[0037] First, both communication and sensing systems are based on electromagnetic wave theory, utilizing the transmission and reception of electromagnetic waves to acquire and transmit information. Second, both communication and sensing systems possess structures such as antennas, transmitting devices, receiving devices, and signal processors, meaning there is significant overlap in their hardware resources.

[0038] Furthermore, with the development of technology, communication systems and sensing systems are increasingly overlapping in their operating frequency bands.

[0039] Furthermore, communication systems and sensing systems share similarities in key technologies such as signal modulation and reception detection, and waveform design.

[0040] For example, the integrated communication and radar system is a typical application of the integrated communication and sensing system.

[0041] In traditional technologies, radar systems and communication systems are strictly distinguished due to their different research objects and focuses; that is, in most scenarios, radar systems and communication systems are studied separately. However, since both radar systems and communication systems are typical methods of information transmission, acquisition, processing, and exchange, and they share many similarities in their working principles, system architecture, and operating frequency bands, the design of integrated radar and communication systems is highly feasible.

[0042] Currently, the methods for realizing integrated communication and radar systems include any of the following:

[0043] Spectrum coexistence: This means that communication and radar systems can operate independently, allowing information exchange to reduce mutual interference.

[0044] Shared receiver equipment: This means that the communication system and the radar system share the same receiver equipment. Specifically, the transmitting equipment of the communication system can transmit communication signals, and the transmitting equipment of the radar system can transmit radar signals. The waveforms of the communication signals and the radar signals are orthogonal, ensuring that the receiving equipment can accurately receive both signals. In other words, the transmitting ends of both systems send their respective signals, and the waveforms of these signals are orthogonal, thus not affecting the receiving equipment's ability to receive and detect both radar and communication signals.

[0045] Transmitter sharing: This means that the communication system and the radar system share the same transmitting equipment. Specifically, the transmitting equipment can transmit a combined waveform of radar signals and communication signals; then the receiving equipment of the communication system can receive this combined waveform and detect the communication signal from it. Similarly, the receiving equipment of the radar system can receive this combined waveform and detect the sensing signal from it.

[0046] Transceiver sharing: This means that the communication system and the radar system share the transmitting and receiving equipment, that is, the two systems share resources on both the transmitting and receiving sides. Specifically, the transmitting equipment can transmit a combined waveform of radar signals and communication signals, or separately transmit communication signals and radar signals with orthogonal waveforms.

[0047] Figure 1 A block diagram of an integrated communication and sensing system provided in an embodiment of this application is shown, such as... Figure 1 As shown, in integrated communication and sensing systems, radio frequency modules are generally reused as common modules, for example... Figure 1 The baseband processor includes a TxRadio Frequency (Tx RF) module, a first optional switch / filter, a Tx array, an Rx array, a second optional switch / filter, and an Rx Radio Frequency (Rx RF) module. A portion of the baseband processor can simultaneously process communication and sensing signals, for example... Figure 1 The shared baseband module in the baseband processor is another module that can be used to process communication signals or sensing signals, for example... Figure 1 The system includes the CommsBaseband module and the Sensing Baseband module.

[0048] When the integrated communication and sensing system is performing sensing, (1) the integrated communication and sensing system can be used as a single-site mode sensing system, i.e., co-located transmit and receive; specifically, the transmitting end device in the integrated communication and sensing system transmits sensing signals, and then the transmitting end device receives the echo signals and analyzes the received echo signals to extract sensing parameters from the echo signals; such as Figure 2 The schematic diagram of the sensing system based on single-site mode shows that base station 01 serves as the transmitting and receiving device for sensing signals, and user equipment UE 02 or other object 03 serves as the sensing target.

[0049] Alternatively, (2), the integrated communication and sensing system can be a system based on dual-station / multi-station sensing mode, i.e., the transmit and receive are not co-located; specifically, the transmitting end device in the integrated communication and sensing system transmits a sensing signal, the receiving end device in the integrated communication and sensing system receives the sensing signal, and analyzes the received sensing signal to extract sensing parameters from the received sensing signal; such as Figure 3The schematic diagram of the sensing system based on dual-station / multi-station mode shows that base station 04 is the transmitting device of sensing signals, and user equipment UE 05 or base station 06 is the receiving device of sensing signals; at least one of objects, environment and events other than base station 04, UE 05 and base station 06 (e.g. object 07) is the sensing target.

[0050] UE can also be referred to as a terminal device or terminal. A UE can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), etc. Wearable devices include smartwatches, wristbands, headphones, glasses, etc. It should be noted that the specific type of UE is not limited in the embodiments of this application. A base station may be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting and receiving point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that the embodiments of this application only take the base station in the NR system as an example, but do not limit the specific type of base station.

[0051] It should be noted that in an integrated communication and sensing system, the receiving device needs to know the type and format of the signal transmitted by the transmitting device before it can differentiate and process the signal. If the receiving device is used as a receiver in a dual-site / multi-site sensing system, it needs to receive and analyze the sensing signals to obtain sensing parameters. If the receiving device is not used as a receiver in a dual-site / multi-site sensing system, or if the transmitting device is operating in single-site sensing mode, the receiving device does not need to receive sensing signals.

[0052] Currently, research on integrated communication and sensing systems is still in its early stages, and there are no unified standards for the signal formats of communication signals, sensing signals, and integrated communication and sensing signals in such systems. Therefore, improving the efficiency of signal processing by receiving devices and reducing the complexity of signal processing in integrated communication and sensing systems are problems that need to be solved.

[0053] In the signal transmission method provided in this application embodiment, the transmitting device can send configuration information indicating the signal to be transmitted by the transmitting device (such as the first signal in this application embodiment) to the receiving device via signaling. After receiving the signaling, the receiving device can distinguish and process the first signal based on the configuration information indicated by the signaling (the description of the configuration information will be detailed in the following embodiments). This can improve the efficiency of signal processing by the receiving device in the integrated communication and sensing system and reduce the complexity of signal processing by the receiving device.

[0054] The information processing method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0055] This application provides a signal transmission method. Figure 4 A schematic diagram of a signal transmission method provided in an embodiment of this application is shown.

That is, indicating whether the receiving device performs communication information detection on the first signal in the first information is a way of implicitly indicating the type of the first signal.

[0109] For example, when the first signal is a sensing signal (and / or a communication sensing integrated signal), the first resource configuration may include at least one of the number of time units for transmitting the sensing signal (and / or the communication sensing integrated signal) and the time unit index.

[0110] Optionally, in this embodiment of the application, the power of the transmitted signal corresponding to the first signal can be within a power range.

[0111] For example, the power of the transmitted signal corresponding to the first signal can be within the power range of -20dBm to 23dBm, and the power of the transmitted signal corresponding to the first signal can be taken as a value every 2dBm within this power range.

[0112] In this embodiment of the application, the signal types of the signals included in the first signal are different, and the configuration information of the first signal may also be different.

[0113] Optionally, in embodiments of this application, when the first signal includes a sensing signal and / or a communication sensing integrated signal, the configuration information of the first signal may include at least one of the target measurement quantity and the signal sequence information.

[0114] For example, if the first signal is a sensing signal and / or a communication sensing integrated signal, then the transmitting end instructs the receiving end device via a first signaling that the receiving end device needs / is to measure a quantity related to the first signal (i.e., the aforementioned target measurement quantity). In this way, the receiving end device can measure only the measurement quantity indicated in the first signaling without measuring other measurement quantities, thereby reducing complexity.

[0115] For example, if the first signal is a sensing signal and / or a communication-sensing integrated signal, then the transmitting end instructs the receiving end device via a first signaling to provide the signal sequence information of the first signal. In this case, the receiving end device acts as a receiver in a dual-station / multi-station mode sensing, meaning the receiving end device needs to receive the first signal and perform sensing signal analysis and processing on the first signal to obtain the sensing parameters.

[0116] Optionally, in embodiments of this application, when the first signal includes a communication signal and / or a communication-sensing integrated signal, the configuration information of the first signal may include an MCS, an MCS table, and a CQI table.

[0117] It is understandable that if the first signal is a communication and sensing integrated signal, then the transmitting device can instruct the receiving device through the first signaling: the MCS, MCS table, and CQI table of the first signal.

[0118] Optionally, in this embodiment of the application, after the receiving device receives the first signaling, if the receiving device needs to receive the first signal sent by the sending device within the target time unit, the receiving device can receive the first signal and process the first signal according to the instruction of the first signaling; if the receiving device does not need to receive the first signal sent by the sending device within the target time unit, the sending device can receive the echo signal of the first signal and process the echo signal based on the configuration information of the first signal; it can be understood that in this case, the receiving device does not receive the first signal and therefore does not process the first signal.

[0119] It should be noted that the receiving device does not need to receive the first signal transmitted by the sending device within the target time unit in the following situations:

[0120] 1. If the first signal is a communication signal and the receiving device is a sensing receiver, then the receiving device does not need to receive the first signal; that is, the sensing receiver only receives the sensing signal sent by the sending device.

[0121] 2. If the first signal is a sensing signal, and the receiving device is a non-sensing signal receiver, for example, the transmitting end adopts a single-station sensing mode, or the transmitting end adopts a dual-station / multi-station sensing mode, but the receiving end does not have the function of receiving sensing signals (in this case, the receiving end only needs to receive the communication signals sent by the transmitting end).

[0122] In this embodiment of the application, the signal type of the first signal is different, and the way the receiving device processes the first signal may also be different.

[0123] It should be noted that the basic condition for the receiving device to process the first signal is that the receiving device knows the signal type of the first signal; that is, the configuration information includes at least the first information, so as to notify / instruct the receiving device of the signal type of the first signal through the first information; thus, the receiving device can determine the way to process the first signal according to the signal type of the first signal.

[0124] Furthermore, if the configuration information also includes other information besides the first information (hereinafter referred to as target information for ease of description), such as at least one of the following: signal waveform, target measurement quantity, signal sequence information, first resource configuration, transmitted signal power, MCS, MCS table, and CQI table, then the receiving device can quickly process the first signal according to the target information.

[0125] Optionally, in this embodiment of the application, when the configuration information includes the first information, the receiving device can process the first signal in any one of the following methods: method 1, method 2, and method 3:

[0126] Method 1: When the configuration information indicates that the first signal is a sensing signal, the receiving device does not restore the communication information in the first signal, and performs sensing signal detection in the first signal according to the configuration information.

[0127] Method 2: When the configuration information indicates that the first signal includes a sensing integrated signal, the receiving device can recover the communication information in the first signal, and / or detect the sensing signal in the first signal according to the configuration information.

[0128] Method 3: If the configuration information indicates that the first signal includes a communication signal, the receiving device restores the communication information in the first signal.

[0129] It is understandable that after the receiving device detects the sensing signal in the first signal according to the configuration information, it can obtain feedback information associated with the target measurement quantity. This feedback information can also be called the sensing parameter (value).

[0130] Optionally, in the embodiments of this application, the first signaling can be any of the following: higher layer signaling, media access control-control unit (MAC CE) signaling, or layer 1 signaling.

[0131] It should be noted that in actual implementation, the first signaling can also be transmitted through a data transmission channel. For example, the transmitting device can transmit the first signaling through the Physical downlink shared channel (PDSCH).

[0132] Optionally, in the embodiments of this application, the Layer 1 signaling can be any of the following: System Information Block (SIB) signaling, Master Information Block (MIB) signaling, or Downlink Control Information (DCI) signaling.

[0133] Optionally, in the embodiments of this application, when the first signaling is Layer 1 signaling, if the Layer 1 signaling is specifically DCI signaling, the configuration information of the first signal can be indicated by any of the following: a specific field in the DCI signaling, adding a specific field to the DCI signaling, applying different scrambling methods to the DCI signaling, or a specific DCI format.

[0134] It is understandable that configuration information can be reused from the original DCI format by indicating specific fields in DCI signaling and by adding specific fields to DCI signaling.

[0135] It is understandable that when configuration information is indicated by scrambling DCI signaling in different ways, different scrambling methods are associated with different information in the configuration information.

[0136] It is understood that when configuration information is indicated through a specific DCI format, that specific DCI format is associated with the configuration information (e.g., signal type). For example, the specific format DCI differs from the original DCI format in length and / or indication field.

[0137] The following will provide examples illustrating the methods used to specify each piece of information in the configuration information.

[0138] 1) For signal type, it can be indicated by at least one of the following methods: higher layer signaling, specific field in DCI signaling, adding specific field to DCI signaling, different scrambling methods for DCI signaling, specific DCI format, that is, DCI format is associated with signal type.

[0139] a) Utilize existing DCI signaling, such as specific fields in DCI 1_x signaling, to indicate the signal type.

[0140] b) Add an X-bit field to the original DCI signaling, such as DCI 1_x signaling, to indicate the signal type. c) Indicate the signal type by applying different scrambling methods to the DCI signaling, for example, by scrambling the DCI signaling with a specific Radio Network Temporary Identity (RNTI), where the specific RNTI is associated with the signal type. d) Indicate the signal type using a specific DCI format, which is associated with the signal type (e.g., sensing signal or integrated communication sensing signal). Specifically, this could be achieved by the specific DCI format differing in length and / or indicating field from the original DCI format.

[0141] 2) For signal waveforms, they can be indicated by at least one of the following methods: higher-layer signaling, specific fields in DCI signaling, adding specific fields to DCI signaling, applying different scrambling methods to DCI signaling, or specific DCI formats, i.e., DCI formats are associated with signal waveforms.

[0142] 3) For MCS, the MCS can be indicated through specific fields in the DCI signaling.

[0143] 4) For MCS and CQI forms, the following methods can be used to indicate: higher-level signaling, specific fields in DCI signaling, adding fields to DCI signaling, applying different scrambling methods to DCI signaling, or specific DCI formats.

[0144] It should be noted that when a specific DCI format is used to indicate the MCS form and / CQI form, after the receiving device receives the DCI signaling of a specific format associated with the signal type / waveform, the transmitting and receiving parties (i.e., the receiving device and the transmitting device) of the first signal (e.g., the first signal includes a communication sensing integrated signal) will by default use the dedicated MCS form or CQI form of the communication sensing integrated signal that was agreed upon in advance.

[0145] 5) For the first configuration information, it can be indicated in at least one of the following ways: a specific field in the DCI, or by adding a specific field in the DCI.

[0146] Optionally, in this embodiment of the application, the first signaling may include M signaling messages, and the configuration information of the first signal can be indicated by at least one of the M signaling messages, where M is a positive integer. That is, it can be understood that the configuration information of the transmission signal (e.g., the first signal) from the transmitting device to the receiving device can be indicated by one or more signaling messages.

[0147] Optionally, in this embodiment, assuming the configuration information of the first signal includes at least two pieces of second information, each piece of second information can be any of the following: first information, the signal waveform of the first signal, or the signal sequence information of the first signal; then, if the at least two pieces of second information are related, for example, in a one-to-one correspondence, the first signaling can specifically be used to indicate at least one of the at least two pieces of second information, or the first signaling can specifically be used to indicate index information related to the at least two pieces of second information. Of course, each piece of the at least two pieces of second information can also be indicated separately. The specific details can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0148] In the signal transmission method provided in the embodiments of this application, since the transmitting device can indicate the configuration information of the first signal to the receiving device via a first signaling, the receiving device can distinguish and process the first signal according to the indication of the first signaling after receiving the first signaling, thereby improving the efficiency of the receiving device in processing signals and reducing the processing complexity.

[0149] Optionally, in this embodiment, the first signaling can also be used to indicate relevant information of the feedback channel. The relevant information of the feedback channel may include at least one of the following: the transmission format of the feedback channel, the time-domain resources of the feedback channel, and the frequency-domain resources of the feedback channel. Here, the feedback channel is the channel used by the receiving device to send feedback information, and the feedback information is associated with the target measurement.

[0150] It should be noted that the correlation between feedback information and target measurement can be understood as: the information obtained by the receiving device after measuring the target measurement, that is, the feedback information is the result obtained by the receiving device after measuring the target measurement.

[0151] For example, feedback information may include size, color, material, etc., detected by the receiving device based on the first signal.

[0152] Optionally, in the embodiments of this application, after step 101 above, the signal transmission method provided in the embodiments of this application may further include the following steps 403 and 404.

[0153] Step 403: The receiving device sends feedback information to the sending device.

[0154] Step 404: The sending device receives the feedback information sent by the receiving device.

[0155] The feedback information is associated with the target measurement.

[0156] Optionally, in this embodiment, the receiving device may execute step 403 if the configuration information includes a target measurement quantity, and the target measurement quantity includes the measurement quantity to be fed back by the receiving device. Alternatively, the receiving device may execute step 403 if the receiving device and the sending device have pre-agreed on the need to feed back feedback information. The specific implementation can be determined based on actual usage requirements, and this embodiment does not impose any limitations.

[0157] In this embodiment of the application, since the receiving device can send feedback information associated with the target measurement to the sending device, the sending device can know the object, event or environment sensed by detecting the first signal after receiving the feedback information.

[0158] Optionally, in this embodiment of the application, it is assumed that the configuration information of the first signal does not include the first resource configuration, which can save costs. After step 402 above, the signal transmission method provided in this embodiment of the application may further include step 405 below.

[0159] Step 405: The receiving device does not receive the first signal, or receives the first signal according to the default format.

[0160] Optionally, in this embodiment of the application, the transmitting device can perform semi-persistent scheduling of the first signal through the first signaling, or the transmitting device can perform dynamic scheduling of the first signal through the first signaling. The specific scheduling can be determined according to actual usage requirements, and this embodiment of the application does not limit it.

[0161] It is understood that in this embodiment of the application, if the transmitting device performs semi-persistent scheduling on the first signal, the transmitting device can send the semi-persistently scheduled first signal to the receiving device; if the transmitting device performs dynamic scheduling on the first signal, the transmitting device can send the dynamically scheduled first signal to the receiving device.

[0162] Optionally, in this embodiment of the application, assuming that the first signal is a signal to be transmitted by the transmitting device in the target time unit, the transmitting device can dynamically schedule and / or semi-persistently schedule the first signal to be transmitted in at least one time unit in the target time unit.

[0163] Optionally, in this embodiment of the application, if the transmitting device needs to dynamically schedule the second signal through the second signal during the semi-persistent scheduling of the first signal by the transmitting device through the first signaling, and the first resource conflicts with the second resource, the signal transmission method provided in this embodiment of the application may further include the following steps 406 and 407, or may include the following steps 408 and 109.

[0164] Step 406: The transmitting device sends a second signaling message to the receiving device and cancels the sending of the first signal for semi-persistent scheduling to the transmitting device.

[0165] Step 407: The receiving device receives the second signaling sent by the sending device and performs the reception and processing of the second signaling according to the instructions of the second signaling.

[0166] The second signal may include at least one type of signal, the first resource may be the transmission resource corresponding to the semi-persistently scheduled first signal, and the second resource may be the transmission resource corresponding to the dynamically scheduled second signal.

[0167] In this embodiment of the application, the second signaling is sent by the transmitting device during the semi-persistent scheduling of the first signal, when the transmitting device needs to dynamically schedule the second signal through the second signaling and when the first resource and the second resource conflict. The second signaling is used to indicate / notify the transmitting device that it needs to dynamically schedule the second signal.

[0168] Optionally, in this embodiment of the application, the transmission resources corresponding to the signal may include at least one of the following: time-domain resources, frequency-domain resources, time-frequency-domain resources, and spatial resources. The spatial resources may be the beam direction.

[0169] It should be noted that, in the embodiments of this application, the transmission resource conflict corresponding to the two signals can be understood as: the time domain resources, frequency domain resources or time-frequency domain resources required to transmit the two signals at least partially overlap.

[0170] It should be noted that the receiving device's reception and processing of the second signal according to the second signaling instruction can be understood as the receiving device receiving and processing the dynamically scheduled second signal according to the configuration information of the second signal indicated by the third signaling. For a detailed description of the configuration information of the second signal, please refer to the relevant description of the configuration information of the first signal in the above embodiments; to avoid repetition, it will not be repeated here.

[0171] As can be seen, in steps 406 and 407, the transmitting device avoids the conflict between the transmission resources corresponding to the semi-persistently scheduled signal and the transmission resources of the signal to be dynamically scheduled by canceling the semi-persistent scheduling of the first signal and dynamically scheduling the second signal.

[0172] Step 408: The transmitting device does not send the second signaling to the receiving device, but continues to send the first signal of semi-persistent scheduling to the transmitting device.

[0173] Step 409: The receiving device receives the first signal of the semi-persistent scheduling sent by the sending device.

[0174] It can be seen that in steps 408 and 409, the transmitting device avoids the conflict between the transmission resources corresponding to the semi-persistently scheduled signal and the transmission resources of the signal to be dynamically scheduled by abandoning the dynamic scheduling of the second signal and continuing to perform semi-persistent scheduling of the first signal.

[0175] Optionally, in the embodiments of this application, the above steps 406 / 408 can be performed after the above step 401.

[0176] In this embodiment of the application, when the transmission resources corresponding to the semi-persistently scheduled signal conflict with the transmission resources corresponding to the dynamically scheduled signal, the transmitting device can, on the one hand, cancel the semi-persistent scheduling of the first signal and dynamically schedule the second signal; on the other hand, the transmitting device can abandon the dynamic scheduling of the second signal and continue to semi-persistently schedule the first signal. Therefore, the conflict between the transmission resources corresponding to the semi-persistently scheduled first signal and the transmission resources corresponding to the dynamically scheduled second signal can be avoided.

[0177] Optionally, in this embodiment of the application, the first time point and the second time point satisfy a first preset time interval, and the first time point is earlier than the second time point. The first time point is the time when the transmitting device sends the second signaling, and the second time point is the time when the transmitting device next sends the first signal for semi-persistent scheduling.

[0178] Optionally, in the embodiments of this application, the "receiving and processing the second signal according to the instruction of the second signaling" in step 407 above can be implemented by step 407a below.

[0179] Step 407a: When the second preset time interval is met between the third time point and the fourth time point, and the third time point is earlier than the fourth time point, the receiving device receives and processes the second signal according to the instructions of the second signaling.

[0180] The third time point is the time when the receiving device receives the second signaling, and the fourth time point is the time when the receiving device receives the first signal of the semi-persistent scheduling next time.

[0181] Optionally, in the embodiments of this application, the second preset time interval may be the same as or different from the first preset time interval.

[0182] In this embodiment of the application, since the receiving device receives and processes the second signal according to the instruction of the second signaling only when the second preset time interval is met between the third time point and the fourth time point, and the third time point is earlier than the fourth time point, it can be ensured that the receiving device can accurately receive and process the signal.

[0183] Optionally, in the embodiments of this application, the "receiving and processing the second signal according to the instruction of the second signaling" in step 407 above can be replaced by step 407b below.

[0184] Step 407b: If the second preset time interval is not met between the third time point and the fourth time point, the receiving device does not receive and process the second signal according to the instructions of the second signaling, and sends error information back to the sending device.

[0185] For details regarding the description in step 407b, please refer to the relevant descriptions in the above embodiments. To avoid repetition, they will not be repeated here.

[0186] In this embodiment of the application, since the receiving device does not receive and process the second signal according to the instructions of the second signaling when the second preset time interval is not met between the third time point and the fourth time point, the receiving device can accurately receive and process the signal.

[0187] Optionally, in this embodiment of the application, if the transmitting device needs to perform semi-persistent scheduling on the third signal, and the transmission resources corresponding to different types of signals in the third signal conflict, then: after step 402 above, the signal transmission method provided in this embodiment of the application may further include the following steps 410 and 411.

[0188] Step 410: The transmitting device sends a third signaling message to the receiving device, and sends a fourth signaling message to the receiving device in accordance with the third signaling message.

[0189] Step 411: The receiving device receives the third signaling sent by the sending device and performs the reception and processing of the fourth signaling according to the instructions of the third signaling.

[0190] The third signal includes at least two types of signals; the fourth signal is one type of signal among the third signals; the third signaling is sent by the transmitting device when the transmitting device needs to perform semi-persistent scheduling of the third signal and the transmission resources corresponding to different types of signals in the third signal conflict; the third signaling is used to indicate that the transmitting device needs to perform semi-persistent scheduling of the fourth signal.

[0191] It should be noted that the receiving device's reception and processing of the fourth signal according to the instructions of the third signaling can be understood as: the receiving device receiving and processing the semi-persistent scheduling fourth signal according to the configuration information of the fourth signal indicated by the third signaling. For a detailed description of the configuration information of the fourth signal, please refer to the relevant description of the configuration information of the first signal in the above embodiments; to avoid repetition, it will not be repeated here.

[0192] Optionally, in the embodiments of this application, the transmitting device can be any of the following: a base station, a UE, or a sensing server; the receiving device can be a base station or a UE.

[0193] The signal transmission method provided in the embodiments of this application will be described exemplarily below with reference to specific examples (Examples 1 to 3 below).

[0194] Example 1:

[0195] In this example, the transmitting device can dynamically schedule the signals to be transmitted within each time unit (e.g., the first signal in this embodiment), and the time unit can be at least one of TTI, slot, and sub-slot. Wherein, as... Figure 5 As shown, the transmitting device can transmit only one type of signal in each time unit, or, as... Figure 6 As shown, the transmitting device can send multiple types of signals in each time unit.

[0196] In this example, the transmitting device can send a signaling message to the receiving device in each time unit. This signaling message instructs the receiving device on configuration information for a specific type of signal transmitted by the transmitting device in the current time unit. This configuration information may include at least one of the following: first information, signal waveform, target measurement quantity, signal sequence information, first resource configuration, transmitted signal power, modulation and coding scheme (MCS), MCS table, and channel quality indicator (CQI) table. Upon receiving this signaling message, the receiving device can then receive and process the signal transmitted by the transmitting device in the current time unit according to the instructions in the signaling message.

[0197] One method involves instructing the receiving device via DCI signaling that the signal transmitted by the transmitting device within the current time unit is at least one of a communication signal, a sensing signal, and a communication-sensing integrated signal. The specific method of indication may include at least one of the following:

[0198] 1) Utilize the original DCI signaling, such as specific fields in DCI 1_x signaling, to indicate the signal type.

[0199] 2) Add an X-bit field to the original DCI signaling, such as DCI 1_x signaling, to indicate the signal type.

[0200] 3) Indicate signal type by scrambling DCI signaling in different ways. For example, use a specific Radio Network Temporary Identity (RNTI) to scramble DCI signaling, where the specific RNTI is associated with the signal type.

[0201] 4) Use a specific DCI format to indicate the signal type. This specific DCI format is associated with the signal type (e.g., sensing signal or integrated communication and sensing signal). Specifically, the specific DCI format may differ from the original DCI format in length and / or indication field.

[0202] Alternatively, the transmitting device instructs the receiving device via DCI signaling regarding the time-frequency resource configuration and / or spatial resource configuration of a specific type of signal transmitted by the transmitting device in the current time unit. The specific method of instruction can be as follows:

[0203] 1) If the original DCI format is reused, such as the DCI format of DCI 1_x signaling, the instruction method can be any of the following:

[0204] A) For the case where only one type of signal is transmitted per time unit, specific fields in the original DCI signaling, such as fields indicating the time-frequency / spatial resource configuration of the communication signal or the DCI reserved field, are used to indicate to the receiving device: the time-frequency resource configuration and / or spatial resource configuration of the sensing signal or integrated communication-sensing signal transmitted by the transmitter in the current time unit; the time-frequency resource configuration and / or spatial resource configuration includes at least one of the following:

[0205] a) Time-domain location, including at least one of the time-domain start location and duration;

[0206] b) Frequency domain location, including at least one of the frequency domain start position and bandwidth;

[0207] c) At least one of the predefined transmission time, frequency, or time-frequency pattern;

[0208] d) Signal direction / beam direction, precoding / beamforming vector or related indication information;

[0209] e) QCL relationship, specifically including at least one of the following: QCL signal source, that is, the QCL relationship satisfied by the sensing signal or integrated sensing signal transmitted by the transmitting device and the communication signal (e.g., SSB, TRS, DMRS), other sensing signals and integrated sensing signals; QCL type, such as QCL-typeA, QCL-typeB, QCL-typeC, QCL-typeD or other QCL types.

[0210] B) For cases where the transmitting device transmits different types of signals in each time unit, a specific field in the original DCI can be used to indicate the time-frequency resource configuration and / or spatial resource configuration of the sensing signal and / or integrated communication-sensing signal transmitted by the transmitting end in the current time unit. This specific field can be a reserved field or a field indicating the configuration information of the original communication signal (i.e., a new interpretation of the original field when it is determined that the DCI signaling is used for scheduling sensing signals or integrated communication-sensing signals). See the above embodiment for an explanation of time-frequency resource configuration / spatial resource configuration.

[0211] C) For cases where different types of signals are transmitted in each time unit, an X-bit field is added to the original DCI to indicate the time-frequency resource configuration / spatial resource configuration of the sensing signal or communication-sensing integrated signal sent by the receiving end in the current time unit. For an explanation of the time-frequency resource configuration / spatial resource configuration, please refer to the above embodiment.

[0212] 2) If a specific format DCI is used, a specific field in the specific format DCI indicates the time-frequency resource configuration / spatial resource configuration of the sensing signal or communication sensing integrated signal sent by the receiving end in the current time unit. For an explanation of the time-frequency resource configuration / spatial resource configuration, please refer to the above embodiment.

[0213] Furthermore, the transmitting end may not instruct the receiving end on time-frequency resource configuration / spatial resource configuration in the DCI to save overhead. In this case, the receiving end will not receive the sensing signal or communication-sensing integrated signal in that time unit, or will receive the sensing signal or communication-sensing integrated signal in that time unit according to the default format.

[0214] In another approach, the transmitting device instructs the receiving device via DCI signaling to provide the signal waveform and sequence information of a specific type of signal transmitted by the transmitting device within the current time unit. The specific method of instruction can be at least one of the following:

[0215] 1) If the original DCI format is reused, such as the DCI format of DCI 1_x signaling, the indication method can be:

[0216] A) Utilize specific fields in the original DCI signaling to indicate the signal waveform and sequence information of the sensing signal or integrated communication sensing signal sent by the receiving end. The specific fields can be reserved fields or fields that indicate the original communication signal configuration information (i.e., when it is determined that the DCI signaling is used for the scheduling of sensing signals or integrated communication sensing signals, the original fields are reinterpreted).

[0217] B) Indicate signal type by scrambling DCI signaling in different ways, such as scrambling with a specific RNTI, where the RNTI is associated with signal waveform or sequence information;

[0218] C) Add an X (X is a positive integer) bit field to the original DCI signaling to indicate the signal waveform and sequence information of a specific type of signal sent by the receiving device and the transmitting device.

[0219] a) If a specific format DCI is used, then a specific field in the specific format DCI indicates the signal waveform and sequence information of the specific type of signal transmitted by the receiver.

[0220] Furthermore, if at least two of the signal type, signal waveform, and sequence information are related, such as in a one-to-one correspondence, then these at least two can be jointly indicated. For example, the transmitting device can indicate at least one of the index number (the index number of the index that the at least two commonly correspond to), signal type, signal waveform, and sequence information via DCI signaling, as shown in Table 1.

[0221] Table 1:

[0222] Index 1 communication signal Waveform 1 - Index 2 Sensing signals Waveform 2 Sequence 1 Index 3 Communication perception integrated signal Waveform 3 Sequence 2

[0223] Example 2

[0224] In this example, the transmitting device can dynamically schedule signals to be transmitted within multiple time units (such as the first signal mentioned above). The time unit can be at least one of TTI, slot, and sub-slot. For example, Figure 7 As shown, the transmitting device can transmit only one type of signal in each time unit, or, as... Figure 8 As shown, the transmitting device can send multiple types of signals in each time unit.

[0225] In this example, the transmitting device can send a signaling message to the receiving device within the multiple time units (specifically, the signaling message can be sent to the receiving device in the first of the multiple time units). This signaling message instructs the receiving device on the configuration information of a specific type of signal to be transmitted by the transmitting device within the multiple time units. This configuration information may include at least one of the following: first information, signal waveform, target measurement quantity, signal sequence information, first resource configuration, transmitted signal power, modulation and coding scheme (MCS), MCS table, and channel quality indicator (CQI) table. Upon receiving the signaling message, the receiving device can then receive and process the signal transmitted by the transmitting device within the multiple time units according to the instructions of the signaling message.

[0226] In one approach, the transmitting end instructs the receiving end via DCI signaling regarding the time-frequency / spatial resource configuration of the transmitted sensing signal and / or integrated communication sensing signal across multiple time units.
