[0137] In the embodiments of the present disclosure, the terms "first," "second," and the like are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

[0138] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0139] Communication and perception fusion (abbreviated as synaesthesia fusion, communication and perception integration, or synaesthesia integration) refers to the unified design of communication and perception functions through joint design of air interfaces and protocols, reuse of time-frequency-space resources, and sharing of hardware devices, so that wireless networks can realize perception functions while performing communication interactions, thereby improving the overall performance and service capabilities of the network. Wireless perception is a technology that uses wireless signals to obtain characteristic information of the environment and / or objects in the environment (such as shape, size, direction, speed, position, distance between objects or relative motion, etc.). Wireless perception services rely on the analysis of the transmission, reflection, and scattering of wireless perception signals. As part of the wireless communication network, wireless perception services provide the possibility of enhancing the use of telecommunications infrastructure in areas such as object detection and tracking, environmental monitoring, and human motion monitoring. Wireless perception services provide inputs for various vertical fields (including drones, smart homes, vehicle to everything (V2X), factories, etc.). For example, some specific use cases include:

[0140] (1) Used for object and intruder detection in predefined security areas around smart homes, highways, railways, factories, and critical infrastructure.

[0141] (2) Collision avoidance and trajectory tracking of drones, vehicles, and automated guided vehicles.

[0142] (3) Automatic control and navigation.

[0143] (4) Public safety search and rescue.

[0144] (5) Rainfall monitoring and flood monitoring.

[0145] (6) Health and exercise monitoring.

[0146] Base stations and terminals (also known as user equipment, UE) in a synaesthesia fusion system need to transmit and / or receive wireless signals. Based on the received wireless signals, the base station or terminal can obtain perception measurement data, and based on the perception measurement data, perception information can be obtained.

[0147] FIG1 is a flow chart of a dual-base sensing method provided by an embodiment of the present disclosure. As shown in FIG1 , the method includes the following steps:

[0148] Step 100: Alternately send and receive sensing signals with the opposite device to sense the sensing target.

[0149] The alternate sending and receiving of sensing signals with the peer device includes:

[0150] Receiving a perception signal from a peer device on a first time domain resource;

[0151] Determine a transmission parameter based on the perception signal received on the first time domain resource, where the transmission parameter includes a transmission parameter for sending the perception signal;

[0152] The perception signal is sent using the sending parameter on the second time domain resource.

[0153] Specifically, the method is performed by any one of the sensing devices in the dual-base sensing. For example, assuming that the sensing devices in the dual-base sensing are respectively called the first device and the second device, the method is performed by the first device (the opposite device is the second device) or the second device (the opposite device is the first device).

[0154] The first device and the second device can be two spatially separated devices, and both the first device and the second device can send and receive perception signals. The first device can be a network device (e.g., a base station) or a terminal, and the second device can also be a network device or a terminal. The first device or the second device is a logical device and may be composed of multiple modules, multiple functions, or multiple devices.

[0155] A sensing signal refers to a wireless signal used for sensing. A sensing signal can be a wireless signal dedicated to sensing, or a wireless signal used for both sensing and communication.

[0156] The second time domain resource is the time domain resource after the first time domain resource. In bistatic sensing, the process of alternating transmission and reception between the two sensing devices includes: a sensing device (taking the second device as an example, its counterpart is the first device) receives a sensing signal sent by the counterpart device on the first time domain resource. The second device then determines transmission parameters based on the sensing signal received on the first time domain resource. The transmission parameters include transmission parameters for sending the sensing signal. Next, the second device uses the transmission parameters to send the sensing signal on the second time domain resource. The first device receives the sensing signal sent by the second device on the second time domain resource. The first device can then determine transmission parameters based on the sensing signal received on the second time domain resource (the transmission parameters include transmission parameters for sending the sensing signal). The first device then uses the determined transmission parameters when sending the next or next set of sensing signals. In this way, the first and second devices alternately transmit and receive sensing signals. Both the first and second devices can adaptively adjust the transmission parameters to maintain continuous perception of the sensing target. The sensing target can be any object, such as a vehicle, a living thing, a drone, or the environment. The sensing target can include one or more sensing targets.

[0157] In some embodiments, the transmission parameters include one or more of a transmission beam parameter and a transmission power, wherein the transmission beam parameter may include at least one of the following: a transmission beam direction and a transmission beam width.

[0158] The first time domain resource may include a time domain resource for transmitting the perception signal once or multiple times. When the first time domain resource includes a time domain resource for transmitting the perception signal multiple times, the opposite device transmits the perception signal multiple times on the first time domain resource, and the perception device receives the perception signal sent by the opposite device multiple times on the first time domain resource.

[0159] The second time domain resources may include time domain resources for transmitting the perception signal once or multiple times. When the second time domain resources include time domain resources for transmitting the perception signal multiple times, the perception device sends the perception signal multiple times on the second time domain resources, and the opposite device receives the perception signal multiple times on the second time domain resources.

[0160] The third time domain resource described later is similar, and the subsequent sending or receiving situations are also similar.

[0161] The transmission parameters determined by the sensing device or the opposite device may be transmission parameters used for multiple transmissions of the sensing signal. The transmission parameters for each of the multiple transmissions may be the same or different.

[0162] An application scenario involving multiple transmissions of a sensing signal may be, for example, transmission in multiple directions to scan multiple directions.

[0163] FIG2 is an example diagram of time domain resources including multiple transmissions of perception signals provided by an embodiment of the present disclosure. As shown in part (a) of FIG2 , the second time domain resource follows the first time domain resource, and both the first time domain resource and the second time domain resource include time domain resources for multiple transmissions of perception signals. As shown in part (b) of FIG2 , the second time domain resource follows the first time domain resource, and the third time domain resource follows the second time domain resource, and the first time domain resource, the second time domain resource, and the third time domain resource all include time domain resources for multiple transmissions of perception signals. It should be understood that the figure is merely an example, and in practice, the first time domain resource, the second time domain resource, and the third time domain resource do not necessarily all include time domain resources for two transmissions of perception signals. For example, the first time domain resource may include time domain resources for three transmissions of perception signals, the second time domain resource may include time domain resources for four transmissions of perception signals, and so on.

[0164] In the present disclosure, the perception signals sent on different time domain resources may be the same signal or different signals. This applies to the case where the perception signal is transmitted multiple times in the first time domain resource, the second time domain resource, or the third time domain resource (for example, the perception signals transmitted multiple times may be the same signal or different signals), and also to the case where the perception signal is transmitted between the first time domain resource, the second time domain resource, or the third time domain resource (for example, the perception signals transmitted on different time domain resources may be the same signal or different signals).

[0165] It should be noted that during the process of alternately transmitting and receiving sensing signals between the sensing devices, the sensing devices may determine transmission parameters based on the sensing signals received on the first time domain resource. In some cases, the sensing devices may also determine the transmission parameters based on other means. That is, "determining the transmission parameters based on the sensing signals received on the first time domain resource" is an optional step. For example, if the sensing target is moving at high speed or the received sensing signal power is low, the sensing device may not be able to perceive the target well. In this case, the sensing device may not rely on the received sensing signal to determine the transmission parameters, but may use other means to determine the transmission parameters to maintain continuous perception of the sensing target.

[0166] In the dual-base sensing method provided by the embodiments of the present disclosure, after a sensing device receives a sensing signal from a peer device on a first time domain resource, it determines a transmission parameter based on the sensing signal received on the first time domain resource, and then uses the transmission parameter to send the sensing signal on a second time domain resource. This method can adaptively adjust the transmission parameter during the alternating transmission and reception process to maintain continuous perception of the sensing target. This not only solves the problem of continuous perception of moving targets in the dual-base sensing mode, but also avoids signaling interaction and saves signaling overhead.

[0167] In some embodiments, determining a transmission parameter based on a perception signal received on a first time domain resource includes:

[0168] determining, based on the perception signal received on the first time domain resource, perception data related to the perception target;

[0169] Transmission parameters are determined based on the sensing data related to the sensing target.

[0170] Specifically, in this embodiment, when the perception device determines the transmission parameters, it first determines the perception data related to the perception target based on the received perception signal, and then determines the transmission parameters based on the perception data.

[0171] In some embodiments, the perception data related to the perception target includes one or more of the following: the speed of the perception target, the distance between (the perception device that determines the transmission parameters) and the perception target, the direction of the perception target, the position of the perception target, the perception measurement quantity related to the perception target, the speed offset of the perception target, the distance offset of the perception target, the direction offset of the perception target, the perception measurement quantity offset of the perception target, the speed range of the perception target, the distance range of the perception target, and the direction range of the perception target.

[0172] In some embodiments, the perception measurement quantity includes one or more of time delay, Doppler frequency shift, angle of arrival, perceived signal reception strength, and channel state information.

[0173] For example, after the sensing device receives the sensing signal on the first time domain resource, it first determines the position of the sensing target based on the received sensing signal, and then determines the transmission beam direction based on the position of the sensing target. The transmission beam direction can be the direction aimed at the position of the sensing target.

[0174] In some embodiments, the transmission parameters further include reception parameters for receiving the perception signal, and the alternate transmission and reception of the perception signal with the peer device further includes:

[0175] The perception signal from the opposite-end device is received using the receiving parameter on the third time domain resource.

[0176] Specifically, the third time domain resource is after the second time domain resource. After the perception device receives the perception signal sent by the opposite device on the first time domain resource, it can determine the sending parameters and receiving parameters based on the perception signal received on the first time domain resource, and use the sending parameters to send the perception signal on the second time domain resource, and use the receiving parameters to receive the perception signal sent by the opposite device on the third time domain resource.

[0177] The third time domain resource may include a time domain resource for transmitting the perception signal once or multiple times. When the third time domain resource includes a time domain resource for transmitting the perception signal multiple times, the peer device transmits the perception signal multiple times on the third time domain resource, and the perception device receives the perception signal sent by the peer device multiple times on the third time domain resource. The example of the third time domain resource including the time domain resource for transmitting the perception signal multiple times can be found in the above description and is not further described here.

[0178] The peer device can determine transmission parameters (including transmit parameters and receive parameters) based on the perception signal received on the second time domain resource, then use the transmit parameters to transmit the perception signal on the third time domain resource, and use the determined receive parameters the next time or the next set of perception signals are received. In this way, the perception device and the peer device alternately transmit and receive perception signals, and both the perception device and the peer device can adaptively adjust the transmit and receive parameters to maintain continuous perception of the perception target.

[0179] In some embodiments, the receiving parameters include receiving beam parameters. The receiving beam parameters may include at least one of the following: receiving beam direction and receiving beam width.

[0180] In the dual-base sensing method provided by the embodiments of the present disclosure, after a sensing device receives a sensing signal from a peer device on a first time domain resource, it determines a sending parameter and a receiving parameter based on the sensing signal received on the first time domain resource, then uses the sending parameter to send the sensing signal on a second time domain resource, and uses the receiving parameter to receive the sensing signal on a third time domain resource. This method can adaptively adjust the sending parameter and the receiving parameter during the alternating transmission and reception process to maintain continuous perception of the sensing target, thereby solving the problem of continuous perception of moving targets in the dual-base sensing mode and avoiding signaling interaction, thereby saving signaling overhead.

[0181] In some embodiments, alternately sending and receiving sensing signals with a peer device further includes:

[0182] A perception signal is received from the opposite-end device on the third time domain resource.

[0183] Specifically, after the second time domain resource, the third time domain resource is received by the sensing device on the first time domain resource from the sensing signal sent by the peer device. The sensing device may determine a transmission parameter based on the sensing signal received on the first time domain resource, use the transmission parameter to send the sensing signal on the second time domain resource, and then receive the sensing signal sent by the peer device on the third time domain resource. When receiving the sensing signal sent by the peer device on the third time domain resource, the reception parameter used is not limited herein and may be, for example, a reception parameter determined based on the sensing signal received on the first time domain resource, or may be a reception parameter determined by other means independent of the received sensing signal.

[0184] The third time domain resource may include a time domain resource for transmitting the perception signal once or multiple times. When the third time domain resource includes a time domain resource for transmitting the perception signal multiple times, the peer device transmits the perception signal multiple times on the third time domain resource, and the perception device receives the perception signal sent by the peer device multiple times on the third time domain resource. The example of the third time domain resource including the time domain resource for transmitting the perception signal multiple times can be found in the above description and is not further described here.

[0185] FIG3 is a diagram illustrating an example of a dual-static sensing process according to an embodiment of the present disclosure. Referring to FIG3 , in this example, a first device transmits (Tx) a sensing signal on time domain resource 1. Correspondingly, a second device receives (Rx) the sensing signal on time domain resource 1. The second device determines transmission parameters, including transmit parameter 1 and receive parameter 1, based on the sensing signal received on time domain resource 1. In some implementations, before transmitting the sensing signal on time domain resource 1, the first device may discover the sensing target through beam scanning or other means, determine the location of the sensing target, and then begin tracking the sensing target, i.e., alternating transmission and reception starting from time domain resource 1.

[0186] Next, the second device sends a perception signal in time domain resource 2 using sending parameter 1. Correspondingly, the first device receives the perception signal in time domain resource 2. The first device determines transmission parameters based on the perception signal received in time domain resource 2, including sending parameter 2 and receiving parameter 2.

[0187] Next, the first device transmits a perception signal on time domain resource 3 using transmit parameter 2. At this point, the second device receives the perception signal on time domain resource 3 based on the previously determined receive parameter 1. The second device then determines transmission parameters, including transmit parameter 3 and receive parameter 3, based on the perception signal received on time domain resource 3. The second device then transmits the perception signal on time domain resource 4 using transmit parameter 3. The first device receives the perception signal on time domain resource 4 based on the previously determined receive parameter 2. In this way, the sensing devices alternately transmit and receive perception signals, achieving continuous tracking of the perception target.

[0188] In this disclosure, the first time domain resource, the second time domain resource, and the third time domain resource are simply different time domain resources that are sequential in time. This disclosure does not limit the specific time domain locations of these time domain resources. For example, referring to Figure 3, any one of time domain resource 1, time domain resource 2, time domain resource 3, and time domain resource 4 in Figure 3 can be the first time domain resource, and correspondingly, the subsequent time domain resources are the second time domain resource and the third time domain resource.

[0189] For example, if the second device receives a perception signal on time domain resource 1, time domain resource 1 is considered the first time domain resource for the second device, and time domain resource 2 and time domain resource 3 are considered the second time domain resource and the third time domain resource, respectively. For example, if the second device receives a perception signal on time domain resource 3, time domain resource 3 can also be considered the first time domain resource for the second device, time domain resource 4 is considered the second time domain resource, and the time domain resource used to transmit the perception signal after time domain resource 4 is considered the third time domain resource.

[0190] For example, the first device receives a perception signal on time domain resource 2. For the first device, time domain resource 2 is the first time domain resource, time domain resource 3 is the second time domain resource, and time domain resource 4 is the third time domain resource. For example, the first device receives a perception signal on time domain resource 4. For the first device, time domain resource 4 can also be considered the first time domain resource. The time domain resources used to transmit the perception signal after time domain resource 4 are the second time domain resource and the third time domain resource, respectively.

[0191] In some implementations, when a sensing device first receives a sensing signal, it may determine a receiving parameter (such as a receiving beam direction) based on the location of the initial sensing target. For example, referring to FIG3 , on time domain resource 2, the first device may determine a receiving beam direction based on the location of the initial sensing target.

[0192] Since there is a period of time between the received perception signal used to determine the transmission parameters and the next or next group of transmitted perception signals, the position of the perception target may have changed during this period. In some implementations, it is possible to consider using a wider transmit beam and / or receive beam, and it is also possible to consider combining historical trajectories to predict the transmit beam direction and / or receive beam direction, so as to be able to send and / or receive perception signals more accurately and maintain continuous perception of the perception target.

[0193] In some embodiments, the method further comprises:

[0194] receiving time domain resource indication information;

[0195] Based on the time domain resource indication information, a time domain resource for sending the perception signal and / or a time domain resource for receiving the perception signal is determined; the time domain resource for receiving the perception signal includes a first time domain resource, and the time domain resource for sending the perception signal includes a second time domain resource.

[0196] In some embodiments, the method further comprises:

[0197] receiving time domain resource indication information;

[0198] Based on the time domain resource indication information, a time domain resource for sending the perception signal and / or a time domain resource for receiving the perception signal is determined; the time domain resource for receiving the perception signal includes the first time domain resource and / or the third time domain resource, and the time domain resource for sending the perception signal includes the second time domain resource.

[0199] Specifically, the perception device can receive time domain resource indication information sent by other devices, and based on the time domain resource indication information, it can determine the time domain resources used to send the perception signal and / or the time domain resources used to receive the perception signal, such as the first time domain resources, the second time domain resources, the third time domain resources, etc.

[0200] The other device may be a peer device, or a device other than the sensing device and the peer device.

[0201] For example, the first device receives time domain resource indication information sent by the second device or a device other than the first device and the second device. Alternatively, the second device receives time domain resource indication information sent by the first device or a device other than the first device and the second device.

[0202] In some embodiments, the second device may send the time domain resource indication information to the first device after receiving the time domain resource indication information sent by devices other than the first device and the second device. The first device is similar and will not be described in detail here.

[0203] In some embodiments, the time domain resource indication information is a Radio Resource Control (RRC) message, an RRC Information Element (IE), a Media Access Control Control Element (MAC CE), or physical layer indication information.

[0204] It should be noted that the names of the various indication information in this disclosure (such as time domain resource indication information, first time domain resource indication information, second time domain resource indication information, third time domain resource indication information, first indication information, second indication information, third indication information, fourth indication information, etc.) do not limit their functions and contents. They are just named differently for the purpose of convenience of description and distinction, but do not constitute a limitation on the function or content of the indication information.

[0205] In some embodiments, the time domain resource indication information includes first time domain resource indication information, where the first time domain resource indication information is used to indicate a time domain resource for sending a perception signal and / or a time domain resource for receiving a perception signal.

[0206] In some implementations, the time domain resources used for sensing signal transmission may be indicated to the sensing device in a semi-static configuration manner.

[0207] For example, referring to Figure 3 , using the four time domain resources in Figure 3 as an example, a first device receives first time domain resource indication information 1. Based on the first time domain resource indication information 1, the first device determines time domain resources 1 and 3 for sending perception signals, and time domain resources 2 and 4 for receiving perception signals. And / or, a second device receives first time domain resource indication information 2. Based on the first time domain resource indication information 2, the second device determines time domain resources 2 and 4 for sending perception signals, and time domain resources 1 and 3 for receiving perception signals. Thereafter, the first and second devices begin alternately transmitting and receiving perception signals on time domain resources 1, 2, 3, and 4. It should be understood that the first time domain resource indication information (first time domain resource indication information 1) received by the first device and the first time domain resource indication information (first time domain resource indication information 2) received by the second device, while both indicating time domain resources for sending perception signals and / or receiving perception signals, are not necessarily the same indication information.

[0208] In some embodiments, the time domain resource indication information includes the resource configuration or resource identifier of the indicated time domain resource.

[0209] In some implementations, when a time domain resource is indicated by a resource identifier, the sensing device obtains the resource configuration of the time domain resource corresponding to the resource identifier through other means (such as receiving other indication information).

[0210] For example, the first device receives first time domain resource indication information, where the first time domain resource indication information indicates the resource configuration of time domain resources (such as time domain resource 1 and time domain resource 3) used to send perception signals, and indicates the resource configuration of time domain resources (such as time domain resource 2 and time domain resource 4) used to receive perception signals.

[0211] In some implementations, the first time domain resource indication information is SensingResourceConfig (sensing resource configuration). ResourceElement (resource element) indicates the configuration information of the time domain resource, txResourceList indicates the time domain resource used to send the sensing signal, including one or more ResourceElements, and rxResourceList indicates the time domain resource used to receive the sensing signal, including one or more ResourceElements. The example information structure is as follows:

[0212] For another example, a first device receives first time domain resource indication information. The first time domain resource indication information indicates, through resource identifiers, that time domain resources 1 and time domain resources 3 are time domain resources for sending perception signals, and / or indicates that time domain resources 2 and time domain resources 4 are time domain resources for receiving perception signals. The first time domain resource indication information indicates resource identifiers of time domain resources (such as time domain resources 1 and time domain resources 3) for sending perception signals, and / or indicates resource identifiers of time domain resources (such as time domain resources 2 and time domain resources 4) for receiving perception signals. In this case, the first device also needs to receive resource configuration information indicating time domain resources 1, time domain resources 2, time domain resources 3, and time domain resources 4.

[0213] In some implementations, the first time domain resource indication information is SensingResourceConfig. ResourceElementId (resource element identifier) ​​indicates the identifier of the time domain resource, txResourceList indicates the time domain resources used to send sensing signals and includes one or more ResourceElementIds, and rxResourceList indicates the time domain resources used to receive sensing signals and includes one or more ResourceElementIds. The example information structure is as follows:

[0214] In some embodiments, the time domain resource indication information includes second time domain resource indication information and / or third time domain resource indication information, the second time domain resource indication information is used to indicate the next or next group of time domain resources for receiving the perception signal, and the third time domain resource indication information is used to indicate the next or next group of time domain resources for sending the perception signal.

[0215] In some implementations, the time domain resources used for sensing signal transmission may be indicated to the sensing device in a dynamic configuration manner. The sensing device receives the time domain resource indication information before the time domain resources indicated by the time domain resource indication information.

[0216] For example, the perception device (taking the second device as an example, its opposite device is the first device) receives the second time domain resource indication information 1, the second time domain resource indication information 1 indicates the first time domain resource for the second device to receive the perception signal (that is, the next or next group of time domain resources for receiving the perception signal, where "next group" refers to the case where the first time domain resource includes a time domain resource for receiving the perception signal multiple times), and the second device receives the perception signal sent by the first device on the first time domain resource; then, the second device receives the third time domain resource indication information 1, and the third time domain resource indication information 1 indicates the second time domain resource for the second device to send the perception signal (that is, the next The second device sends a perception signal on the second time domain resource; then, the second device receives second time domain resource indication information 2, and the second time domain resource indication information 2 indicates a third time domain resource for the second device to receive the perception signal (i.e., the next or next group of time domain resources for receiving the perception signal, where "the next group" refers to the case where the third time domain resource includes a time domain resource for receiving the perception signal multiple times), and the second device receives the perception signal sent by the first device on the third time domain resource.

[0217] For another example, for the opposite device of the perception device (still taking the perception device as the second device as an example, its opposite device is the first device), the first device receives third time domain resource indication information 2, and the third time domain resource indication information 2 indicates the first time domain resource for the first device to send the perception signal (that is, the next or next group of time domain resources for sending the perception signal, where "next group" refers to the case where the first time domain resource includes the time domain resource for sending the perception signal multiple times), and the first device sends the perception signal on the first time domain resource; then, the first device receives second time domain resource indication information 3, and the second time domain resource indication information 3 indicates the first time domain resource for the first device to receive the perception signal. The first device receives the perception signal sent by the second device on the second time domain resource (i.e., the next or next group of time domain resources for receiving the perception signal, where "next group" refers to the case where the second time domain resources include time domain resources for receiving the perception signal multiple times); then, the first device receives the third time domain resource indication information 3, and the third time domain resource indication information 3 indicates the third time domain resource for sending the perception signal (i.e., the next or next group of time domain resources for sending the perception signal, where "next group" refers to the case where the third time domain resources include time domain resources for sending the perception signal multiple times), and the first device sends the perception signal on the third time domain resource.

[0218] In some implementations, when the time domain resource indication information includes second time domain resource indication information and third time domain resource indication information, the sensing device may receive the second time domain resource indication information and the third time domain resource indication information twice. This can also be understood as the second time domain resource indication information and the third time domain resource indication information being sent via two messages.

[0219] For example, referring to Figure 3 , using the four time domain resources in Figure 3 as an example, a first device receives indication information 1 and, based on indication information 1, determines that time domain resource 1 is used for sending a perception signal. The first device then sends the perception signal on time domain resource 1. The first device then receives indication information 2 and, based on indication information 2, determines that time domain resource 2 is used for receiving a perception signal. The first device then receives indication information 3 and, based on indication information 3, determines that time domain resource 3 is used for sending a perception signal. The first device then sends the perception signal on time domain resource 3. The first device then receives indication information 4 and, based on indication information 4, determines that time domain resource 4 is used for receiving a perception signal. The first device then receives indication information 4. Both indication information 2 and 4 are second time domain resource indication information, while both indication information 1 and 3 are third time domain resource indication information. Dynamically configuring time domain resources during the alternating transmission and reception of perception signals by two sensing devices allows for more flexible time domain resource configuration. The second device operates similarly and will not be further described here.

[0220] In some embodiments, the time domain resource indication information includes the resource configuration or resource identifier of the indicated time domain resource.

[0221] In some implementations, when a time domain resource is indicated by a resource identifier, the sensing device obtains the resource configuration of the time domain resource corresponding to the resource identifier through other means (such as receiving other indication information).

[0222] For example, the first device receives second time domain resource indication information, where the second time domain resource indication information indicates a resource configuration of a time domain resource (such as time domain resource 2) for receiving the perception signal.

[0223] For another example, the first device receives second time domain resource indication information. The second time domain resource indication information indicates, through a resource identifier, that time domain resource 2 is a time domain resource for receiving the perception signal. The second time domain resource indication information indicates a resource identifier of the time domain resource (e.g., time domain resource 2) for receiving the perception signal. In this case, the first device also needs to receive resource configuration information indicating time domain resource 2.

[0224] For another example, the first device receives third time domain resource indication information, where the third time domain resource indication information indicates a resource configuration of a time domain resource (such as time domain resource 3) used to send a perception signal.

[0225] For another example, the first device receives third time domain resource indication information. The third time domain resource indication information indicates, through a resource identifier, that time domain resource 3 is a time domain resource for sending a perception signal. The third time domain resource indication information indicates a resource identifier of the time domain resource (e.g., time domain resource 3) for sending the perception signal. In this case, the first device also needs to receive resource configuration information indicating time domain resource 3.

[0226] In some embodiments, the next time domain resource or the next group of time domain resources for receiving the perception signal is one or more time domain resources that are separated by a first time interval from the sending time (which may be the sending start time or the sending end time, not limited in this disclosure) of the second time domain resource indication information. The one or more time domain resources here can be any time domain resources, or can be time domain resources capable of receiving signals, or can be time domain resources capable of receiving perception signals.

[0227] The next time domain resource or the next group of time domain resources for sending the perception signal is one or more time domain resources that are separated by a second time length from the sending time (which may be the sending start time or the sending end time, not limited in this disclosure) of the third time domain resource indication information. The one or more time domain resources here may be any time domain resources, or may be time domain resources capable of sending signals, or may be time domain resources capable of sending perception signals.

[0228] Specifically, the first duration and the second duration can be any duration, and are not specifically limited. The first duration and the second duration can be the same or different.

[0229] For example, the perception device receives the second time domain resource indication information, and determines the earliest one or more time domain resources after the sending time of the second time domain resource indication information by a time interval of T1 as the next or next group of time domain resources for receiving the perception signal, where T1 represents the first duration, and T1 is greater than or equal to 0.

[0230] For another example, after receiving the second time domain resource indication information, the perception device determines one or more time domain resources that are T1 time intervals from the time when the second time domain resource indication information is sent. These one or more time domain resources can be used by the perception device to receive the perception signal until the next third time domain resource indication information indicates the time domain resources for the perception device to send the perception signal. Taking indication information 2 and indication information 3 as examples, in some embodiments, after receiving indication information 2, the perception device determines one or more time domain resources starting from T1 time intervals from the time when indication information 2 is sent and ending at T1 time intervals from the time when indication information 3 is sent as time domain resources for the first device to receive the perception signal.

[0231] For another example, the perception device receives the third time domain resource indication information, and determines the earliest one or more time domain resources after the sending time of the third time domain resource indication information at an interval of T2 as the next or next group of time domain resources for sending the perception signal, where T2 represents the second duration, and T2 is greater than or equal to 0.

[0232] For another example, after receiving the third time domain resource indication information, the perception device determines one or more time domain resources that are T2 times later than the time when the third time domain resource indication information is sent. These one or more time domain resources can be used by the perception device to send a perception signal until the next second time domain resource indication information indicates a time domain resource for the perception device to receive the perception signal. Taking indication information 1 and indication information 2 as examples, in some embodiments, after receiving indication information 1, the perception device determines one or more time domain resources starting from T2 times later than the time when indication information 1 is sent and ending at T2 times later than the time when indication information 2 is sent as time domain resources for the first device to send a perception signal.

[0233] In some embodiments, the method further comprises:

[0234] Based on the speed and / or perception performance of the perception target, start or end the alternating sending and receiving of the perception signal with the opposite end device.

[0235] Specifically, in this embodiment, the start or end conditions of alternating transmission and reception can be set, and the sensing device can decide to start or end alternating transmission and reception based on the speed and / or sensing performance (such as the sensing signal receiving power) of the sensing target.

[0236] In some embodiments, starting or ending alternating transmission and reception of sensing signals with a peer device based on the speed and / or sensing performance of the sensing target includes:

[0237] When the first condition is met, starting to alternately send and receive sensing signals with the opposite device;

[0238] The first condition includes one or more of the following:

[0239] The speed of the perceived target is lower than or equal to a first threshold;

[0240] It is perceived that the signal received power is greater than or equal to a second threshold.

[0241] For example, when the speed of the perceived target meets a first criterion, the first device and the second device may alternately transmit and receive the perception signal. The perception target speed meeting the first criterion may specifically be that the speed of the perceived target is lower than or equal to a first threshold.

[0242] For another example, when the sensing performance satisfies a second criterion, the first device and the second device may alternately transmit and receive the sensing signal. The sensing performance satisfies the second criterion, which may specifically be that the received power of the sensing signal is greater than or equal to a second threshold.

[0243] The first threshold and the second threshold are arbitrary thresholds and can be set flexibly without any specific restrictions.

[0244] In some embodiments, starting or ending alternating transmission and reception of sensing signals with a peer device based on the speed and / or sensing performance of the sensing target includes:

[0245] When the second condition is met, the alternating sending and receiving of the sensing signal with the opposite device is terminated;

[0246] The second condition includes one or more of the following:

[0247] The speed of the perceived target is higher than or equal to the third threshold;

[0248] The sensing signal received power is lower than or equal to a fourth threshold.

[0249] For example, if the speed of the perceived target meets a third criterion, the method of alternately sending and receiving the perception signal using the first device and the second device may be terminated. Specifically, the speed of the perceived target meeting the third criterion may be: the speed of the perceived target is greater than or equal to a third threshold.

[0250] For another example, the method of alternately sending and receiving the sensing signal using the first device and the second device may be terminated when the sensing performance satisfies a fourth criterion. The sensing performance satisfies the fourth criterion, which may specifically be that the sensing signal received power is lower than or equal to a fourth threshold.

[0251] The third threshold and the fourth threshold are arbitrary thresholds and can be set flexibly without any specific restrictions.

[0252] In some embodiments, the method further comprises:

[0253] Sending first indication information to the opposite device, where the first indication information is used to indicate starting or ending the alternating sending and receiving of the perception signal.

[0254] For example, the first device determines to start or end alternately transmitting and receiving sensing signals based on the speed and / or sensing performance of the sensing target. The first device may send first indication information to the second device to instruct the second device to start or end alternately transmitting and receiving sensing signals. The second device is similar and will not be described in detail here.

[0255] In some embodiments, the method further comprises:

[0256] receiving second indication information sent by the opposite device;

[0257] Based on the second indication information, start or end the alternating sending and receiving of the perception signal with the opposite device.

[0258] For example, the second device determines to start or end the alternating transmission and reception of the perception signal based on the speed and / or perception performance of the perception target, and the second device sends second indication information to the first device, and the first device starts or ends the alternating transmission and reception of the perception signal according to the second indication information.

[0259] In some embodiments, the method further comprises:

[0260] receiving third indication information sent by the opposite device, where the third indication information is used to indicate the perception data related to the perception target and / or parameter information related to the transmission parameter;

[0261] Based on the third indication information, transmission parameters used for the next transmission of the perception signal or the next group of perception signals are determined.

[0262] Specifically, in order to prevent the sensing method of alternately transmitting and receiving sensing signals from failing to perceive the target well in certain circumstances, signaling may be used to assist in adjusting transmission parameters.

[0263] In some implementations, the parameter information related to the transmission parameter may be information about the transmission parameter itself, that is, the third indication information indicates the transmission parameter used for the perception signal transmission.

[0264] In some implementations, the parameter information related to the transmission parameter may be information used to determine related parameters of the transmission parameter (such as an offset of the transmission parameter, a value range of the transmission parameter, etc.).

[0265] In some embodiments, the method further comprises:

[0266] Send fourth indication information to the opposite device, where the fourth indication information is used to indicate the perception data related to the perception target and / or parameter information related to the transmission parameter.

[0267] Specifically, signaling can be used to assist in adjusting transmission parameters. Either of the two sensing devices can send indication information to the other device. For example, a first device sends fourth indication information to a second device, where the fourth indication information indicates sensing data related to a sensing target and / or parameter information related to transmission parameters. The second device determines the transmission parameters to be used for the next transmission or the next set of sensing signal transmissions based on the fourth indication information.

[0268] In some embodiments, sending fourth indication information to the opposite device includes:

[0269] If the third condition is met, sending fourth indication information to the opposite device;

[0270] The third condition includes one or more of the following:

[0271] The speed of the perceived target is higher than or equal to the fifth threshold;

[0272] The sensing signal received power is lower than or equal to a sixth threshold.

[0273] For example, the first device may send fourth indication information to the second device when the speed of the perceived target meets the fifth criterion. The speed of the perceived target meeting the fifth criterion may specifically be: the speed of the perceived target is higher than or equal to a fifth threshold.

[0274] For another example, the first device may send fourth indication information to the second device when the perceived performance meets a sixth criterion. The perceived performance meeting the sixth criterion may specifically be: the perceived signal received power is lower than or equal to a sixth threshold.

[0275] The fifth threshold and the sixth threshold are arbitrary thresholds and can be flexibly set without specific restrictions.

[0276] The following describes the methods provided by the above embodiments of the present disclosure by taking an example of a specific application scenario and combining it with FIG3 .

[0277] Example 1: The first device and the second device alternately send and receive sensing signals to sense the same or multiple sensing targets. The main process includes:
