[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).
[0041] Sensing Network
[0042] In a narrow sense, a perception network can refer to a system with the capabilities of target positioning, target imaging, target detection, target tracking, and target recognition. Target positioning can include one or more of the following perception operations on the perceived target: ranging, speed measurement, and angle measurement.
[0043] In a broad sense, a perceptual network can refer to a system that has the attributes and status of any business, network, user, terminal, and environmental objects.
[0044] From the perspective of perception applications, perception can be classified into the following categories: outdoor / wide-area / local-area applications and indoor / local-area applications.
[0045] Outdoor / wide-area / local-area applications may include one or more of the following: smart cities, smart transportation / high-speed rail, and low-altitude applications.

[0047] It should be noted that the above-mentioned applications of perception and classification of perception applications are exemplary, and the application scope of perception is not limited to the above examples.
[0048] Perception and communication integration
[0049] Perception is a key application of modern RF technology. Perception can be achieved using radio waves. For example, perception technology can use radio waves to detect parameters of the physical environment to achieve environmental awareness, such as target location, motion recognition, and imaging. Another important application of modern RF technology is wireless communication. Separate designs for perception and wireless communication can lead to waste of wireless spectrum and hardware resources.
[0050] With technological advancements, in some networks (such as 6G or beyond 5G (B5G) networks), communication spectrum can be based on millimeter waves, terahertz, visible light, and other technologies. In other words, the wireless communication spectrum can overlap with the perception spectrum. Next-generation networks (such as 6G networks) may be a fusion of at least two of the following: mobile communication networks, perception networks, and computing power networks.
[0051] Integrated communication and perception technology can merge wireless communication and perception functions. This technology can enable a wide range of capabilities. For example, it can leverage wireless communication resources to implement perception. Alternatively, it can leverage widely deployed cellular networks to provide perception services over a wider range. Furthermore, it can leverage network equipment and multiple terminal devices for joint perception, achieving higher perception accuracy. Furthermore, it can reuse wireless communication hardware modules to implement perception functions, reducing costs.
[0052] It is understandable that integrated communication and perception technology can enable wireless communication systems to have perception capabilities, providing a foundation for the development of smart transportation, smart cities, smart factories, drones and other businesses.
[0053] During the perception process, there may be at least one of the following types of nodes: a perception node, a perceived target, and a perception control node.
[0054] A sensing node may include a sensing signal sending node and / or a sensing signal receiving node. The sensing signal sending node and the sensing signal receiving node may be the same entity. Taking the eight sensing modes shown in Figure 2 as an example, the sensing node may be a network device in Mode 1 or a terminal device in Mode 2. In Mode 1, the sensing signal sending node and the sensing signal receiving node are the same entity, which is a network device. In Mode 2, the sensing signal sending node and the sensing signal receiving node are the same entity, which is a terminal device.
[0055] The sensed target may be a target that needs to be sensed. In some embodiments, the sensed target may also be referred to as a sensed node or a measured target.
[0056] A perception control node may be a node that controls and manages perception nodes and / or perception services. The functions of a perception control node may include, but are not limited to, managing perception services, sending configuration information to perception nodes and / or perceived targets, configuring the sending and / or reception of perception measurement signals, configuring the sending and / or reception of perception signals, configuring the perception nodes and / or perceived targets to report measurement results and / or perception results, and collecting and processing measurement results and / or perception results. It should be noted that the perception control node may be the same entity as the perceived target, the perception signal sending node, or the perception signal receiving node. Alternatively, the perception control node may be a separate entity from the perception signal and perceived target.
[0057] Perception can be achieved through different modes. Figure 2 shows an example of eight modes of perception.
[0058] Figure 2(a) is an example diagram of mode 1. Among them, mode 1 is the self-transmitting and self-receiving perception of the network device. As shown in Figure 2(a), the sending node of the signal / channel used for perception (hereinafter referred to as the perception signal / channel) is the network device 210a (such as gNB). After the network device 210a sends the perception signal (sensing signal), it is reflected by the perceived target 230 (such as the vehicle shown in Figure 2(a)), and the reflected signal (reflected signal) returns to the network device 210a (it can also be considered that the perception signal returns to the network device 210a). The network device 210a is both the sending node of the perception signal / channel and the receiving node of the perception signal / channel. The signal / channel described in the embodiment of the present application can also be referred to as a channel / signal.
[0059] Figure 2(b) illustrates an example of Mode 2. Mode 2 involves the terminal device transmitting and receiving its own perception. As shown in Figure 2(b), the sending node of the perception signal / channel is terminal device 220a. After terminal device 220a transmits the perception signal, it is reflected by the perceived target 230 (such as the vehicle shown in Figure 2(b)), and the reflected signal returns to terminal device 220a (which can also be considered the perception signal returning to terminal device 220a). Terminal device 220a is both the sending node and the receiving node of the perception signal / channel.
[0060] Figure 2(c) illustrates Mode 3, which involves collaborative sensing between network devices. As shown in Figure 2(c), the sensing signal / channel is transmitted by a network device 210a (e.g., a gNB). After network device 210a transmits the sensing signal, it is reflected by a sensed target 230 (e.g., a vehicle shown in Figure 2(c)). The reflected signal is then transmitted to another network device 210b (which can also be considered the sensing signal being transmitted to another network device 210b). Network device 210b is the receiving node for the sensing signal / channel.
[0061] Figure 2(d) shows an example of Mode 4, which involves terminal collaborative sensing. As shown in Figure 2(d), the sensing signal / channel is transmitted by terminal device 220a. After terminal device 220a transmits the sensing signal, it is reflected by a sensed target 230 (such as the vehicle shown in Figure 2(d)). The reflected signal is then transmitted to another terminal device 220b (which can also be considered the sensing signal being transmitted to terminal device 220b). Terminal device 220b is the receiving node of the sensing signal / channel.
[0062] Figure 2(e) illustrates Mode 5, which involves collaborative network-end-device sensing. The sensing signal / channel is transmitted by network device 210a (e.g., a gNB). After network device 210a transmits the sensing signal, it is reflected by target 230 (e.g., a vehicle shown in Figure 2(e)). The reflected signal is then transmitted to end-device 220a (which can also be considered the sensing signal being transmitted to end-device 220a). End-device 220a then receives the sensing signal / channel.
[0063] Figure 2(f) illustrates an example of Mode 6, which involves collaborative sensing between terminal devices and network devices. The sensing signal / channel is transmitted by terminal device 220a. After transmitting the sensing signal, it is reflected by target 230 (such as the vehicle shown in Figure 2(f)). The reflected signal is then transmitted to network device 210a (which can also be considered the sensing signal being transmitted to network device 210a). Network device 210a then receives the sensing signal / channel.
[0064] Figure 2(g) illustrates an example of Mode 7. In Mode 7, the target being sensed is the node that sends the sensing signal / channel. For example, terminal device 220a, acting as the target, sends a sensing signal to network device 210a (e.g., a gNB). Network device 210a receives the sensing signal and senses terminal device 220a.
[0065] Figure 2(h) illustrates an example of Mode 8. In Mode 8, the target being sensed is the receiving node of the sensing signal / channel. For example, network device 210a (e.g., a gNB) transmits a sensing signal, and terminal device 220a is the receiving node of the sensing signal / channel. After receiving the sensing signal, terminal device 220a sends a feedback signal to network device 210a.
[0066] In the case where the communication system has sensing capabilities, it has not yet been determined which signal or channels are used for sensing. For example, a new signal or channel can be defined specifically for sensing.
[0067] This application proposes a communication method that performs a sensing function based on one or more of a data signal / channel and a reference signal / channel in a communication system. Figure 3 illustrates a communication method provided by an embodiment of this application. The method shown in Figure 3 can be performed by a first device and / or a second device.
[0068] It should be noted that the first device, second device, and third device referred to in this application may be any of the communication devices described above. It is understood that if a communication device has perception capabilities, the communication device may also be referred to as a perception communication device. For example, the first device, second device, or third device may be a terminal device or network device in the eight perception modes described above.
[0069] The method shown in FIG. 3 may include S310 .
[0070] S310: A first device receives one or more perception signals, and a second device sends one or more perception signals.
[0071] The perception signal may be a reference signal and / or a signal carried in a data channel. In other words, the present application proposes that the perception signal may reuse some of the signals in the wireless communication system. In some cases, the perception signal proposed in the present application may be an enhancement of the reference signal and / or the signal carried in the data channel, i.e., enabling the reference signal and / or the signal carried in the data channel to have perception capabilities.
[0072] Reference signals may include uplink reference signals, downlink reference signals, and sidelink reference signals.
[0073] Uplink reference signals may include, but are not limited to, sounding reference signals (SRS) and phase tracking reference signals (PT-RS). In wireless communication systems, SRS can be used for uplink channel quality measurement and uplink beam management, while PT-RS can be used for phase tracking during communication.
[0074] Downlink reference signals may include, but are not limited to, synchronization signal blocks (SSBs), channel state information-reference signals (CSI-RSs), PT-RSs, and positioning reference signals (PRSs). In wireless communication systems, SSBs can be used by terminal devices to achieve downlink synchronization with network equipment; CSI-RSs can be used for time-frequency tracking, downlink beam management, and downlink channel quality measurement during communication; and PRSs can be used for positioning.
[0075] The sidelink reference signal may include a synchronization signal block transmitted in a sidelink, a CSI-RS signal, etc.
[0076] In a wireless communication system, a data channel can carry communication data. The data channel may include, but is not limited to, one or more of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), and a physical sidelink shared channel (PSSCH). The signal carried in the data channel may include one or more of a data signal carried by the data channel and a demodulation reference signal (DMRS). The data signal may include, but is not limited to, one or more of the following: an uplink data signal (e.g., a signal carried in PUSCH), a downlink data signal (e.g., a signal carried in PDSCH), and a sidelink data signal (e.g., a signal carried in PSSCH). The transmission of the data signal / channel corresponds to the transmission of the DMRS signal at the same time, which is used to demodulate the data channel.
[0077] The perception signal can enable perception of the environment around the first device and / or the second device.
[0078] It is understandable that generalized perception can be achieved through sensing signals. That is, the first device can have a generalized wireless sensing capability through sensing signals. In some embodiments, the environment around the first device and / or the second device may include a sensed target. The sensed target may include any object around the first device and / or the second device. For example, the sensed target may be a communication device (such as a terminal device), a non-communication device, or an animal or plant. Through sensing signals, the position, shape, distance, angle, moving speed, motion trajectory, breathing frequency, special form (such as falling) of the sensed target can be detected and / or perceived. Alternatively, through sensing signals, detection, perception, imaging, and map construction of the surrounding environment can be achieved.
[0079] In this way, perception can be achieved without defining new signals or channels, thereby reducing the standardization workload of perception and communication integration, and also reducing the complexity and system overhead of the system. In addition, for the reference signal, the bandwidth of the reference signal can be relatively large, therefore, multiplexing the reference signal for perception can at least achieve higher-precision perception. For the signal carried in the data channel, the signal is a signal that usually needs to be sent during the communication process, therefore, multiplexing the signal in the data channel for perception can at least reduce the overhead of perception. The present application does not limit the implementation method of perception. For example, detection or perception of the perceived target can be achieved by measuring the perception signal and the reflection of the perception signal. In some embodiments, a signal (or echo signal) reflected by the perceived target for the perception signal can be received, and the perceived target can be perceived based on the transmission delay of the echo signal and / or the result feedback information of the perception signal. For example, the third device can measure the azimuth of the echo signal based on the echo signal to sense the orientation of the target object.
[0080] It should be noted that the perception described in this application is a broad perception. For example, perception may include one or more of positioning, detection, ranging, angle measurement, imaging, detection, tracking, and identification.
[0081] It should be noted that the term "perception" as used herein can be replaced by other terms related to perception. For example, one or more of the following can be used to replace "perception": positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition. As an implementation, a perception signal can also be referred to as a perception communication signal, positioning signal, ranging signal, or target imaging signal.
[0082] As described above, the perception signal of the present application can multiplex one or more of the data signal / channel and the reference signal / channel in the communication system. In other words, the perception signal can be used for perception or communication, or the perception signal can be used for both perception and communication (i.e., the perception signal is used for both perception and communication).
[0083] The first information related to one or more perception signals can be used to determine whether the one or more perception signals are used for perception and / or for communication. In some embodiments, the first device can receive the first information to determine, based on the first information, whether the one or more perception signals are used for perception and / or for communication. The sender of the first information can be the sender of the one or more perception signals (e.g., the second device) or another device.
[0084] When one or more perception signals are used for perception or for both perception and communication, the first device (i.e., the receiving end of the one or more perception signals) may feed back perception result information. Therefore, in some embodiments, the first information may also be used to indicate whether the receiving end needs to feed back perception result information.
[0085] The first information may be included in the configuration information and / or control information corresponding to one or more perception signals. That is, the configuration information and / or control information may include the first information.
[0086] In the case where the configuration information includes the first information, the first device may receive the configuration information to obtain the first information. The configuration information may be sent by the second device, or may be sent by a device other than the first device and the second device.
[0087] In the case where the control information includes the first information, the first device may receive the control information to obtain the first information. The control information may be sent by the second device, or may be sent by a device other than the first device and the second device.
[0088] The configuration information may be used to configure one or more sensing signals. In some embodiments, the configuration information may be carried in a radio resource control (RRC) message, a system information block (SIB) message, or a medium access control (MAC) message.
[0089] The configuration information may include one or more information elements (IEs), and part or all of the information in the first information may be carried in the one or more information elements.
[0090] In some embodiments, when one or more sensing signals are used for sensing, the configuration information may include a first information element. That is, the first information element may be used to configure one or more sensing signals for sensing.
[0091] In some embodiments, when one or more perception signals are used for communication, the configuration information may include a second information element. That is, the second information element may be used to configure one or more perception signals for communication.
[0092] In some embodiments, when one or more sensing signals are used for sensing and communication, the configuration information may include a third information element. That is, the third information element may be used to configure the one or more sensing signals for communication and sensing.
[0093] In some embodiments, when one or more perception signals are used for both communication and perception, the configuration information may include a first information element and a second information element. The first information element may carry a first portion of the first information, and the second information element may carry a second portion of the first information. The first portion of information and the second portion of information may be different. The first portion of information may be used to configure one or more perception signals for perception, and the second portion of information may be used to configure one or more perception signals for communication.
[0094] The following uses the sensing signal as a CSI-RS as an example to explain the first information element and the second information element. The first information element can be used to configure one or more CSI-RSs for sensing, and the second information element can be used to configure one or more CSI-RSs for communication. In other words, the CSI-RS for sensing can be configured through the first information element, and the CSI-RS for communication can be configured through the second information element. The CSI-RS configured by the first information element can be referred to as a CSI-RS for sensing, and the CSI-RS configured by the second information element can be referred to as a CSI-RS for communication.
[0095] The configuration information may include one or more parameters. The one or more parameters may be included in one or more information elements. The one or more information elements may, for example, include one or more of the first information element, the second information element, and the third information element described above. The one or more parameters may include one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter. The first information may be carried in one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter.
[0096] In some embodiments, one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter may be configured in common (or shared) with one or more information cells. For example, the common one or more information cells may include a fourth information cell. The fourth information cell may include one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter. Alternatively, the common multiple information cells may include a fifth information cell and a sixth information cell. The fifth information cell may include one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter. The sixth information cell may include one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, and the fifth parameter. The parameters included in the sixth information cell may be different from the parameters included in the fifth information cell.
[0097] In some embodiments, the configuration information may include a first parameter and / or a second parameter. The first parameter may be used to indicate part or all of the first information, and the second parameter may be used to indicate part or all of the first information.
[0098] In some implementations, when one or more perception signals are used for perception, the configuration information may include a first parameter. That is, if the first parameter is configured, it may indicate that the one or more perception signals are used for perception.
[0099] In some implementations, when one or more perception signals are used for communication, the configuration information may include a second parameter. That is, if the second parameter is configured, it may indicate that the one or more perception signals are used for communication.
[0100] In some implementations, when one or more perception signals are used for communication and perception, the configuration information may include a first parameter and a second parameter. That is, if the first parameter and the second parameter are configured, it can be indicated that the one or more perception signals are used for communication and perception.
[0101] In some implementations, when one or more perception signals are used for communication, the configuration information may not include the first parameter.
[0102] In some implementations, the configuration information may include a fourth parameter. The fourth parameter may be a parameter different from the first parameter and may be used to indicate that one or more perception signals are used for perception. It will be appreciated that when the configuration information includes the second and fourth parameters, the one or more perception signals may be used for both communication and perception.
[0103] In some implementations, when one or more perception signals are used for perception, the configuration information may not include the second parameter.
[0104] In some implementations, the configuration information may include a fifth parameter. The fifth parameter may be a parameter different from the second parameter and may be used to indicate that one or more perception signals are used for communication. It will be appreciated that when the configuration information includes the first and fifth parameters, the one or more perception signals may be used for both communication and perception.
[0105] In some embodiments, the configuration information may include a third parameter, which may be used to indicate the first information. When one or more perception signals are used for perception, the value of the third parameter may include the first value or exclude the second value. That is, when the value of the third parameter in the configuration information corresponding to the one or more perception signals used for perception includes the first value, the one or more perception signals may be used for perception. When one or more perception signals are used for communication, the value of the third parameter may include the second value or exclude the first value. That is, when the value of the third parameter in the configuration information corresponding to the one or more perception signals used for perception includes the second value, the one or more perception signals may be used for communication.
[0106] As an implementation, when one or more perception signals are used for communication and perception, the value of the third parameter may include a third value. The third value may be a value different from the first value and / or the second value. In other words, when the value of the third parameter in the configuration information corresponding to the one or more perception signals used for perception includes the third value, the one or more perception signals may be used for communication and perception.
[0107] The technical solution for including the first information in configuration information has been described in detail above. The following describes the technical solution for including the first information in control information. It is understood that the first information can be included solely in the configuration information, the first information can be included solely in the control information, or the first information can be included in both the configuration information and the control information. In other words, the technical solution for including the first information in the configuration information and the technical solution for including the first information in the control information described above can be implemented separately or in combination.
[0108] It should be noted that the case where the first information is included in the configuration information and / or control information may include the case where the first information is the configuration information and / or control information. The control information can be used to trigger the transmission of one or more perception signals. In other words, the transmission of one or more perception signals can be controlled by the control information corresponding to one or more perception control signals. For example, the control information may include downlink control information (DCI).
[0109] The first information may be carried in the first indication field of the control information. That is, the control information may indicate through the first indication field whether the corresponding one or more perception signals are used for perception, for communication, or for both perception and communication.
[0110] When one or more perception signals are used for perception or for both perception and communication, the first device (i.e., the receiving end of the one or more perception signals) may feed back perception result information. Therefore, in some embodiments, the first indication field may also be used to indicate whether the receiving end needs to feed back perception result information.
[0111] In some implementations, when the value of the first indication field includes a fourth value, one or more perception signals may be used for perception. Alternatively, when the value of the first indication field includes a fifth value, one or more perception signals may be used for communication. Alternatively, when the value of the first indication field includes a sixth value, one or more perception signals may be used for both communication and perception.
[0112] It is understandable that the first information may be included only in the configuration information or the control information, or may be included in both the configuration information and the control information. That is, the first information may be determined through the configuration information. Alternatively, the first information may be determined through the control information. Alternatively, the first information may be determined in combination with the configuration information and the control information. For example, the third part of the first information may be included in the configuration information, and the fourth part of the first information may be included in the control information. The first terminal device may combine the third part of the information and the fourth part of the information to obtain the first information. That is, the third part of the information and the fourth part of the information may constitute the entire information of the first information.
[0113] The above describes the perception signal, and the following describes the feedback of the perception signal. Feedback on the perception signal can be indicated by result feedback information. When the perception signal is used for perception, the result feedback information can be used to indicate perception result feedback information. That is, the result feedback information may include perception result feedback information, which is used to indicate the feedback result for the perception signal. When the perception signal is used for communication, the result feedback information can be used to indicate communication feedback information. In some embodiments, when the perception signal is a reference signal, the communication feedback information may include communication measurement feedback information (e.g., channel measurement results). Alternatively, when the perception signal is a signal carried in a data channel, the communication feedback information may include hybrid automatic repeat request (HARQ) feedback information.
[0114] It should be noted that the result feedback information may correspond to one or more perception signals. That is, one result feedback information may include feedback information for one perception signal, or may include feedback information for multiple perception signals. In some embodiments, multiple perception result feedback information may correspond to multiple perception signals. For example, multiple perception result feedback information may correspond one-to-one with multiple perception signals.
[0115] Figure 4 is a schematic flow chart of a communication method provided in an embodiment of the present application. The method shown in Figure 4 can be performed by a first device and / or a third device. The third device can be any communication device or perception communication device described above. The third device can be the same device as the second device or a different device from the second device. The third device can be a receiving end of a reflected signal of a perception signal. The third device can be an entity where a perception node and / or a perception control node is located.
[0116] The method shown in FIG4 may include S410. In S410, a first device may send perception result feedback information corresponding to one or more perception signals. Correspondingly, a third device may receive the perception result feedback information corresponding to the one or more perception signals.
[0117] It should be noted that the methods shown in FIG. 3 and FIG. 4 can be implemented separately or in combination.
[0118] The following describes the feedback of the perception signal, respectively, for the case where the perception signal is a reference signal and / or a signal carried in a data channel. Case 1 describes the case where the perception signal is a reference signal, and Case 2 describes the case where the perception signal is a signal carried in a data channel. It is understood that the embodiments described in Case 1 and Case 2 below can be implemented in combination. That is, when the perception signal is a reference signal and a signal carried in a data channel, the embodiments described in Case 1 and Case 2 can be combined.
[0119] Case 1: The perception signal is a reference signal
[0120] When the sensing signal is a reference signal, the result feedback information can be periodic, semi-persistent, or aperiodic. The following describes different types of result feedback information. 1) When the result feedback information corresponding to one or more sensing signals is periodic or semi-persistent.
[0121] If the result feedback information is periodic, the result feedback information may not need to be triggered, and the receiving device of the perception signal (i.e., the first device) can periodically feedback the communication and / or perception results. If the result feedback information is semi-continuous, the result feedback information needs to be triggered. After the triggering, the receiving device of the perception signal (i.e., the first device) can periodically feedback the communication and / or perception results.
[0122] The result feedback information can be obtained based on a perception signal that is no later than (earlier than or equal to) a first time unit. The first time unit can be determined based on the time unit occupied by the result feedback information. In some implementations, the first time unit can be one of the one or more time units occupied by the result feedback information. For example, the first time unit can be the first time unit or the last time unit occupied by the result feedback information. In some implementations, the first time unit can be another time unit mapped out from the time unit occupied by the result feedback information. In other words, the first time unit can be determined based on the time unit occupied by the result feedback information.
[0123] Figure 5 is an example diagram of a periodic or semi-persistent result feedback information provided by an embodiment of the application. As shown in Figure 5, the first time unit occupied by the result feedback information can be the first time unit.
[0124] In some embodiments, when the result feedback information is used to indicate communication measurement feedback information, the result feedback information can be obtained based on the first perception signal. The first perception signal can be a perception signal transmitted no later than the first reference time before the first time unit. It can be understood that the first perception signal can be a perception signal sent or received earlier than or equal to the first reference time before the first time unit. For example, the first reference time can be N time units, and the first perception signal can be a perception signal transmitted the Nth time unit before the first time unit, or the first perception signal can be a perception signal transmitted the time unit before the Nth time unit before the first time unit. Wherein, N can be an integer greater than 0. For example, the first reference time can be 12 symbols as shown in Figure 5, and the first perception signal can be a perception signal earlier than or equal to the perception signal 12 symbols before the first time unit, that is, perception signal 3.
[0125] In some embodiments, when the result feedback information is used to indicate the perception result feedback information, the result feedback information can be obtained based on the second perception signal. The second perception signal can be a perception signal sent or received no later than the second reference time before the first time unit. It can be understood that the second perception signal can be a perception signal transmitted earlier than or equal to the second reference time before the first time unit. For example, the second reference time can be M time units, and the second perception signal can be a perception signal transmitted the Mth time unit before the first time unit, or the second perception signal can be a perception signal transmitted the time unit before the Mth time unit before the first time unit. Wherein, M can be an integer greater than 0. For example, the second reference time can be 18 symbols as shown in Figure 5, and the second perception signal can be earlier than or equal to the perception signal 18 symbols before the first time unit, that is, perception signal 4.
[0126] It can be understood that, when the result feedback information is used to indicate both the perception result feedback information and the communication measurement feedback information, the result feedback information can be obtained based on the first perception signal and the second perception signal respectively based on the method described above.
[0127] In some embodiments, when the result feedback information is used to indicate perception result feedback information and communication measurement feedback information, the result feedback information can be obtained based on a third perception signal. The third perception signal can be a perception signal sent or received no later than a third reference time before the first time unit, where the third reference time is obtained based on the first reference time and the second reference time. In some embodiments, the third reference time can be the larger of the first reference time and the second reference time. For example, the first reference time can be 12 symbols as shown in Figure 5, the second reference time can be 18 symbols as shown in Figure 5, and the third reference time can be the larger of the first reference time and the second reference time. That is, the third perception signal can be earlier than or equal to the perception signal 18 symbols before the first time unit, that is, perception signal 4.
[0128] 2) The result feedback information corresponding to one or more sensing signals is non-periodic.
[0129] In the case where the result feedback information is non-periodic, the sending of the result feedback information needs to be triggered. For example, it can be triggered by control information. After the result feedback information is triggered, the receiving device (i.e., the first device) that perceives the signal can feedback the communication and / or perception results.
[0130] The time unit in which the result feedback information corresponding to the one or more perception signals is located can be determined based on the second time unit. The second time unit can be determined based on the time unit in which the one or more perception signals are located, or the second time unit can be determined based on the time unit in which the control information corresponding to the one or more perception signals is located.
[0131] In some embodiments, the second time unit may be the first time unit or the last time unit among the one or more time units occupied by the one or more perception signals. Alternatively, the second time unit may be the first time unit or the last time unit among the one or more time units where the control information corresponding to the one or more perception signals is located.
[0132] In some embodiments, the first or last time unit of the one or more time units occupied by the one or more perception signals may be mapped to another time unit, and the second time unit may be the other time unit. That is, the second time unit may be determined based on the first or last time unit of the one or more time units occupied by the one or more perception signals. Alternatively, the first or last time unit of the one or more time units containing the control information corresponding to the one or more perception signals may be mapped to another time unit, and the second time unit may be the other time unit. That is, the second time unit may be determined based on the first or last time unit of the one or more time units occupied by the control information corresponding to the one or more perception signals.
[0133] In some embodiments, when the result feedback information is used to indicate the perception result feedback information, if the time unit in which the result feedback information is located (for example, the first time unit and / or the last time unit in one or more time units in which the result feedback information is located) is not earlier than the first processing time after the second time unit, the perception result feedback information indicated by the result feedback information may be valid. It is understood that if the time unit in which the result feedback information is located is later than or equal to the first processing time after the second time unit, the one or more perception signal receiving nodes (for example, the first device) may report valid perception result feedback information. If the time unit in which the result feedback information is located is earlier than the first processing time after the second time unit, the one or more perception signal receiving nodes may report invalid perception result feedback information or not report the perception result feedback information, which may depend on the implementation of the first device.
[0134] It should be noted that the first processing time may correspond to or include a period of time (which may be referred to as the first processing time). In some embodiments, the first processing time may occupy one or more time units.
[0135] In some embodiments, when the result feedback information is used to indicate communication measurement feedback information, if the time unit in which the result feedback information is located is not earlier than the second processing time after the second time unit, the communication measurement feedback information indicated by the result feedback information may be valid. It is understood that if the time unit in which the communication measurement feedback information is located is later than or equal to the second processing time after the second time unit, one or more receiving nodes of the perception signal (e.g., the first device) may report valid communication measurement feedback information. If the time unit in which the communication measurement feedback information is located is earlier than the second processing time after the second time unit, one or more receiving nodes of the perception signal may report invalid communication measurement feedback information or not report the communication measurement feedback information, which may depend on the implementation of the first device.
[0136] It should be noted that the second processing time may correspond to or include a period of time (which may be referred to as the second processing time). In some embodiments, the second processing time may occupy one or more time units.
[0137] In some embodiments, the second processing time may be determined based on the first processing time. Alternatively, the first processing time may be determined based on the second processing time. Alternatively, the first processing time and the second processing time may be determined separately, that is, independently of each other.
[0138] It can be understood that, when the result feedback information includes perception result feedback information and communication measurement feedback information, it can be determined based on the method described above whether the communication measurement feedback information and the perception result feedback information are valid.
[0139] In some embodiments, when the result feedback information is used to indicate perception result feedback information and communication measurement feedback information, if the time unit in which the result feedback information is located is not earlier than (later than or equal to) a third processing time after the second time unit, then both the communication measurement feedback information and the perception result feedback information indicated by the result feedback information may be valid. The third processing time may be determined based on the first processing time and the second processing time. In some embodiments, the third processing time may be the maximum of the first processing time and the second processing time. It is understood that if the perception result feedback information and the communication measurement feedback information are transmitted in the same time unit, and the time unit in which the result feedback information is located is later than or equal to the third processing time after the second time unit, one or more receiving nodes of the perception signal may report valid communication measurement feedback information and perception result feedback information. If the time unit in which the result feedback information is located is earlier than the third processing time after the second time unit, one or more receiving nodes of the perception signal may report invalid communication measurement feedback information and perception result feedback information, or the receiving node may not report the communication measurement feedback information and / or perception result feedback information, which may depend on the implementation of the first device.
[0140] It should be noted that the third processing time may correspond to or include a period of time (which may be referred to as the third processing time). In some embodiments, the third processing time may occupy one or more time units.
[0141] It should be noted that one or more of the duration or occupied time unit corresponding to the first processing time, the duration or occupied time unit corresponding to the second processing time, and the duration or occupied time unit corresponding to the third processing time may be predefined, pre-set, or configured. For example, the duration of the first processing time and / or the duration of the second processing time may be agreed upon in a protocol or configured by the perception control node.
[0142] It should be noted that, in case 1, the time unit where the communication measurement feedback information corresponding to one or more perception signals is located and the time unit where the perception result information corresponding to one or more perception signals is located may be the same or different.
[0143] Case 2: The sensing signal is the signal carried in the data channel
[0144] The result feedback information corresponding to the one or more perception signals may include perception result feedback information and / or HARQ feedback information. The time unit in which the perception result feedback information and / or HARQ feedback information is located may be determined based on a second time unit. The second time unit may be determined based on the time unit in which the one or more perception signals are located, or the second time unit may be determined based on the time unit in which the control information corresponding to the one or more perception signals is located. In some embodiments, the second time unit may be the first time unit or the last time unit occupied by the one or more perception signals. In some embodiments, the second time unit may be the first time unit or the last time unit in which the control information corresponding to the one or more perception signals is located.
[0145] In some embodiments, the first or last time unit of the one or more time units occupied by the one or more perception signals may be mapped to another time unit, and the second time unit may be the other time unit. That is, the second time unit may be determined based on the first or last time unit of the one or more time units occupied by the one or more perception signals. Alternatively, the first or last time unit of the one or more time units containing the control information corresponding to the one or more perception signals may be mapped to another time unit, and the second time unit may be the other time unit. That is, the second time unit may be determined based on the first or last time unit of the one or more time units occupied by the control information corresponding to the one or more perception signals.
[0146] In some embodiments, if the time unit in which the perception result feedback information corresponding to the one or more perception signals is located is not earlier than the fourth processing time after the second time unit, the perception result feedback information corresponding to the one or more perception signals is valid. It will be understood that if the time unit in which the result feedback information is located is later than or equal to the fourth processing time after the second time unit, the receiving node of the one or more perception signals may report valid perception result feedback information. If the time unit in which the result feedback information is located is earlier than the fourth processing time after the second time unit, the receiving node of the one or more perception signals may report invalid perception result feedback information or not report the perception result feedback information, which may depend on the implementation of the first device.
[0147] It should be noted that the fourth processing time may correspond to or include a period of time (which may be referred to as the fourth processing time). In some embodiments, the fourth processing time may occupy one or more time units.
[0148] In some embodiments, if the time unit in which the HARQ feedback information corresponding to the one or more perception signals resides is no earlier than the fifth processing time after the second time unit, the HARQ feedback information corresponding to the one or more perception signals is valid. It will be understood that if the time unit in which the HARQ feedback information resides is later than or equal to the fifth processing time after the second time unit, the receiving node of the one or more perception signals may report valid communication measurement feedback information. If the time unit in which the HARQ feedback information resides is earlier than the fifth processing time after the second time unit, the receiving node of the one or more perception signals may report invalid communication measurement feedback information or not report the communication measurement feedback information, which may depend on the implementation of the first device.
[0149] It should be noted that the fifth processing time may correspond to or include a period of time (which may be referred to as the fifth processing time). In some embodiments, the fifth processing time may occupy one or more time units.
[0150] In some embodiments, the fifth processing time may be determined based on the fourth processing time. Alternatively, the fourth processing time may be determined based on the fifth processing time. Alternatively, the fourth processing time and the fifth processing time may be determined separately, that is, independently of each other.
[0151] It can be understood that, when the result feedback information includes both the perception result feedback information and the HARQ feedback information, it can be determined based on the method described above whether the HARQ feedback information and the perception result feedback information are valid.
[0152] In some embodiments, if HARQ feedback information corresponding to one or more perception signals and perception result feedback information corresponding to the perception signals are transmitted in the same time unit, and the same time unit is no earlier than the sixth processing time after the second time unit, then the HARQ feedback information and perception result feedback information corresponding to the one or more perception signals are both valid. The sixth processing time may be determined based on the fourth processing time and the fifth processing time. For example, the sixth processing time may be the maximum of the fourth processing time and the fifth processing time. It is understood that when the perception result feedback information and the HARQ feedback information are transmitted in the same time unit, if the time unit in which the HARQ feedback information and the perception result feedback information are located is later than or equal to the sixth processing time after the second time unit, the receiving node of the one or more perception signals may report valid HARQ feedback information and perception result feedback information. If the time unit in which the HARQ feedback information and the perception result feedback information are located is earlier than the sixth processing time after the second time unit, the receiving node of the one or more perception signals may report invalid HARQ feedback information and perception result feedback information, or the receiving node may not report the HARQ feedback information and / or perception result feedback information, which may depend on the implementation of the first device.
[0153] It should be noted that the sixth processing time may correspond to a period of time. In some embodiments, the sixth processing time may occupy one or more time units.
[0154] It should be noted that one or more of the duration or occupied time unit corresponding to the fourth processing time, the duration or occupied time unit corresponding to the fifth processing time, and the duration or occupied time unit corresponding to the sixth processing time may be predefined, pre-set, or configured. For example, the duration of the fourth processing time and / or the duration of the fifth processing time may be agreed upon in a protocol or configured by the perception control node.
[0155] The time unit where the HARQ feedback information corresponding to the one or more sensing signals is located and the time unit where the sensing result information corresponding to the one or more sensing signals is located may be the same or different.
[0156] In one embodiment, the time unit in which the HARQ feedback information corresponding to the one or more perception signals is located is no later than the time unit in which the perception result feedback information corresponding to the one or more perception signals is located. It is understandable that the first device may obtain the HARQ feedback information before or simultaneously with the reception of the perception result feedback information, thereby determining the condition of the channel (e.g., channel quality) for transmitting the one or more perception signals based on the condition of the HARQ feedback information. For example, when the HARQ feedback information is NACK, the channel quality is poor. Alternatively, when the HARQ feedback information is ACK, the channel quality is good. The first device may also determine whether the perception result feedback information is valid or determine whether to transmit (including sending and / or receiving) the perception result feedback information based on the condition of the channel.
[0157] The following describes in detail the processing of the sensing result feedback information when the HARQ feedback information is in different situations.
[0158] In some embodiments, when the HARQ feedback information is ACK, the first device may transmit perception result feedback information corresponding to one or more perception signals, and the third device may receive the perception result feedback information corresponding to the one or more perception signals. That is, the first device may transmit the perception result feedback information, and the third device may receive the perception result feedback information, only when the one or more perception signals used for communication are correctly demodulated. It is understood that when the HARQ feedback information is ACK, the channel quality for transmitting the one or more perception signals is relatively good. When the channel quality is relatively good, a more accurate perception result can be obtained. In this case, transmitting the perception result feedback information enables more accurate perception.
[0159] In some embodiments, when the HARQ feedback information is NACK, the first device may not send the perception result feedback information corresponding to the one or more perception signals, and the third device may not receive the perception result feedback information corresponding to the one or more perception signals.
[0160] In some embodiments, when the HARQ feedback information is NACK, the first device may send perception result feedback information, and the third device may receive the perception result feedback information, wherein the bits corresponding to the perception result feedback information are preset values. The preset values may be preconfigured or predefined by the protocol. The preset values may be used as placeholders, i.e., the bits corresponding to the perception result feedback information serve as one or more placeholders. In other words, if the bits corresponding to the perception result feedback information are preset values, the perception result feedback information does not transmit the actual perception result. The receiving end of the perception result feedback information may ignore the perception result feedback information.
[0161] Taking the example of HARQ feedback information and perception result feedback information occupying different time units, when the HARQ feedback information is ACK, the first device may transmit the HARQ feedback information in a fourth time unit, and transmit the perception result feedback information corresponding to one or more perception signals in a fifth time unit that is later than the fourth time unit. When the HARQ feedback information is NACK, the first device may transmit the HARQ feedback information in the fourth time unit, and not transmit the perception result feedback information corresponding to the one or more perception signals in a fifth time unit that is later than the fourth time unit. Alternatively, the first device may transmit the perception result feedback information in the fifth time unit, and the corresponding bit of the perception result feedback information is a preset value.
[0162] The following description is made by taking the HARQ feedback information and the sensing result feedback information occupying the same time unit as an example.
[0163] When the HARQ feedback information and the perception result feedback information occupy the same time unit, the coding method of the HARQ feedback information and the perception result feedback information can be an independent coding method or a joint coding method. In the case of independent coding, the HARQ feedback information and the perception result feedback information can be encoded using independent (separate) code rates and / or independently adding cyclic redundancy check (CRC) checks, thereby outputting respective rate-matched output sequences. In the case of joint coding, the HARQ feedback information and the perception result feedback information can use the same code rate to form a bit sequence together, or a CRC check can be added to the bit sequence together to output a rate-matched output sequence.
[0164] In the case of independent coding, when the HARQ feedback information is NACK, the first device may not transmit the perception result feedback information corresponding to the one or more perception signals.
[0165] It is understood that, in the case of independent coding, the HARQ feedback information and the sensing result feedback information are independent of each other, and the coding of the sensing result feedback information does not affect the coding of the HARQ feedback information. In other words, in the case of independent coding, a change in the number of bits of the sensing result feedback information does not affect the demodulation of the HARQ feedback information. Therefore, when the HARQ feedback information is NACK, the sensing result feedback information may not be fed back, thereby reducing communication overhead.
[0166] In the case of joint coding, when the HARQ feedback information is NACK, the first device may transmit the perception result feedback information, and the bit corresponding to the perception result feedback information is a preset value.
[0167] It is understandable that, in the case of joint coding, if the number of bits corresponding to the perception result feedback information changes (for example, when the perception result feedback information is not sent, the number of bits is 0), it may affect the demodulation of the HARQ feedback information. Regardless of whether the HARQ feedback information is ACK or NACK, the bits corresponding to the perception result feedback information must exist and the length must not change. Therefore, setting the bits corresponding to the perception result feedback information to a preset value can enable correct demodulation of the HARQ feedback information.
[0168] The time domain and / or frequency domain resources used for sensing result information feedback may be determined by control information corresponding to one or more sensing signals.
[0169] In some embodiments, the control information may include a second indication field, and the second indication field may be used to indicate the time domain and / or frequency domain resources occupied by the perception result feedback information.
[0170] The second indication field may also be referred to as a perception result feedback resource indication field. The perception result feedback resource indication field may include a time domain resource indication field and / or a frequency domain resource indication field. In some embodiments, the time domain resource indication field may indicate the absolute position of the time domain resource where the perception result feedback information is located. In some embodiments, the time domain resource indication field may indicate the relative position relative to the time domain resource where one or more perception signals are located. In some embodiments, the time domain resource indication field may indicate the relative position of the time domain resource where the control information corresponding to the one or more perception signals is located. The frequency domain resource indication field may indicate the absolute position of the frequency domain resource where the perception result feedback information is located, or the relative position within a preset frequency domain range where one or more perception signals are received at the receiving end.
[0171] Taking the example of the second indication field indicating the time domain resources occupied by the perception result feedback information, the second indication field can be used to indicate the time offset between the perception result feedback information and the second time unit. The second time unit can be determined based on the time unit in which one or more perception signals are located, or the second time unit can be determined based on the time unit in which the control information corresponding to the one or more perception signals is located. For example, the second time unit can be the first time unit or the last time unit occupied by the one or more perception signals. For example, the second time unit can be the first time unit or the last time unit in which the control information corresponding to the one or more perception signals is located.
[0172] In one embodiment, the time unit where one or more perception signals or the control information corresponding to one or more perception signals is located is n, and the offset between the time unit n and the time unit where the perception result feedback information is located is k. Then, the time domain resource where the perception result feedback information is located is determined based on the time unit n and the offset k. For example, if the subcarrier spacing (SCS) of the control information and the perception result feedback information is the same, the time unit where the perception result feedback information is located is n+k. Where n can be an integer greater than or equal to 0, and k can be an integer greater than or equal to 0.
[0173] The time domain resources occupied by the perception result feedback information may be explicitly indicated by the control information. In some embodiments, the time domain resources occupied by the perception result feedback information may be directly indicated by the second indication field. The time domain resources occupied by the perception result feedback information may also be implicitly determined. In some embodiments, the time domain resources occupied by the perception result feedback information may be implicitly determined based on the control information corresponding to one or more perception signals and / or the time domain and / or frequency domain resources where the one or more perception signals are located, according to a preset or configured mapping relationship.
[0174] The communication method provided by this application is described in detail below through Examples 1 to 4.
[0175] Example 1
[0176] The perception signal multiplexes the CSI-RS signal in a communication system (e.g., a NR system). The perception signal can be indicated for perception and / or communication in the following manner.
[0177] Method 1: Configuration information may include a first IE and a second IE. The CSI-RS configured in the first IE may be used for sensing. The CSI-RS configured in the second IE may be used for communication. When both the first IE and the second IE are configured, the CSI-RS can be used for both communication and sensing. The CSI-RS used for sensing and communication can include more fine-grained sub-functions, which will not be detailed here.
[0178] Method 2: The CSI-RS used for sensing and the CSI-RS used for communication can share a common IE configuration. In this IE, the configuration information corresponding to the CSI-RS used for sensing must include the first parameter (parameter 1). In other words, if the first parameter is configured, the CSI-RS is configured for sensing. In some embodiments, the configuration information corresponding to the CSI-RS used for communication may not include the first parameter, or the configuration information corresponding to the CSI-RS used for communication must include the second parameter (parameter 2).
[0179] Method 3: The CSI-RS used for sensing and the CSI-RS used for communication can share an IE configuration, which can include a third parameter. In the configuration information corresponding to the CSI-RS used for sensing, the third parameter must be set to the first value (value 1). In other words, if the value of the third parameter is configured to be the first value, it means that this CSI-RS is configured for sensing. In some embodiments, in the configuration information corresponding to the CSI-RS used for communication, the third parameter must be set to the second value (value 2) or not the first value.
[0180] Example 2
[0181] The perception signal multiplexes the PDSCH or PSSCH channel. The transmitter of the perception signal can send the PDSCH channel or the PSSCH channel, and the PDSCH channel or the PSSCH channel can be used for communication and perception at the same time.
[0182] The Yth processing time may be the fourth processing time, that is, the Yth processing time may be the perception processing time. The Yth processing time may be agreed upon by the protocol or configured by the perception control node. If the time unit where the perception result feedback corresponding to the PDSCH or PSSCH is located is the Yth processing time after the time unit where the PDSCH or PSSCH is located (or the time unit where the control information corresponding to the PDSCH or PSSCH is located), the first signal receiving node reports valid perception result feedback information. Y may be an integer greater than or equal to 0.
[0183] The Xth processing time may be the fifth processing time, that is, the Xth processing time may be the communication processing time. The Xth processing time may be agreed upon by the protocol or configured by the perception control node. If the time unit where the HARQ feedback corresponding to the PDSCH or PSSCH is located is the Xth processing time after the time unit where the PDSCH or PSSCH is located (or the time unit where the control information corresponding to the PDSCH or PSSCH is located), the receiving end of the perception signal may report valid HARQ feedback information. Wherein, X may be an integer greater than or equal to 0.
[0184] Example 3
[0185] The perception signal multiplexes the PDSCH or PSSCH channel. The transmitter of the perception signal can send the PDSCH channel or the PSSCH channel, and the PDSCH channel or the PSSCH channel can be used for communication and perception at the same time.
[0186] If the PDSCH or PSSCH is received correctly, the receiving end feeds back ACK information and sensing result information. If the PDSCH or PSSCH is not received correctly, the receiving end feeds back only NACK information without feeding back the sensing result information, or sets the bit position corresponding to the sensing result information to a preset value. The HARQ feedback information and sensing result information can be encoded separately or jointly.
[0187] Example 4
[0188] The perception signal multiplexes the PDSCH or PSSCH channel. The transmitter of the perception signal can send the PDSCH channel or the PSSCH channel, and the PDSCH channel or the PSSCH channel can be used for communication and perception at the same time.
[0189] The control information corresponding to one or more perception signals may include a first indication field. The first indication field may be referred to as a perception indication field. The perception indication field may be 1 bit, indicating whether one or more perception signals are used for perception, or whether the receiving end needs to feedback perception result information. For example, 1 may indicate that one or more perception signals are used for perception, and 0 may indicate that one or more perception signals are not used for perception.
[0190] The control information corresponding to one or more perception signals may include a second indication field. The second indication field may also be referred to as a perception result feedback resource indication field. The perception result feedback resource indication field may include a time domain resource indication field and / or a frequency domain resource indication field. The time domain resource indication field may indicate the absolute position of the time domain resource where the perception result feedback information is located, or the relative position relative to the time domain resource where the one or more perception signals or the control information corresponding to the one or more perception signals are located. The frequency domain resource indication field may indicate the absolute position of the frequency domain resource where the perception result feedback information is located, or the relative position within a preset frequency domain range where the one or more perception signals are received at the receiving end.
