[0126] ISAC technology, as a novel communication technology in 5G and / or 6G (primarily 6G), aims to integrate sensing capabilities into the design of communication systems, enabling these systems to provide sensing as a service alongside communication. Current research on ISAC technology mainly focuses on scenarios such as TRP-TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, and UE monostatic. During the design process, ISAC systems need to consider the service requirements of both communication and sensing simultaneously.

[0127] The six scenarios described above are described in detail below:

[0128] The base station transmits and receives signals (or gNB transmits and receives signals, i.e., TRP monostatic). The base station transmits sensing signals, which, after passing through the environment or objects in the environment, are received and measured by the base station as reflected / scattered waves. In this scenario, the first and second devices in this disclosure can be the same network device (e.g., a base station or a base station's TRP).

[0129] Base station A transmits and base station B receives (or gNB A transmits and base station B receives, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, which passes through the environment or objects in the environment, and base station B receives and measures the reflected / scattered waves. In this scenario, the first device in this disclosure can be a first network device (e.g., base station A or base station TRP A), and the second device can be a second network device (e.g., base station B or base station TRP B).

[0130] The terminal transmits and the base station receives (or the UE transmits and the gNB receives, i.e., UE-TRP bistatic). The terminal sends a sensing signal, which, after passing through the environment or objects in the environment, is received by the base station to measure the reflected / scattered waves. In this scenario, the first device in this disclosure can be a terminal, and the second device can be a network device (e.g., a base station or the base station's TRP).

[0131] The base station transmits and the terminal receives (or the gNB transmits and the UE receives, i.e., TRP-UE bistatic). The base station sends a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave. In this scenario, the second device in this disclosure can be a terminal, and the first device can be a network device (e.g., a base station or the base station's TRP).

[0132] The terminal transmits and receives signals independently (or the UE transmits and receives signals independently, i.e., UE monostatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the terminal receives and measures the reflected / scattered waves. In this scenario, the first device and the second device in this disclosure can be the same terminal.

[0133] Terminal A transmits and B receives (or UE A transmits and B receives, i.e., UE-UE bistatic). Terminal A sends a sensing signal, which passes through the environment or objects in the environment, and terminal B receives and measures the reflected / scattered waves. In this scenario, the first device in this disclosure can be a first terminal (e.g., terminal A), and the second device can be a second terminal (e.g., terminal B).

[0134] In sensing services, resource allocation is a core issue. Generally, resource allocation can be semi-static or dynamic. Semi-static resource allocation is typically suitable for periodic services, where sensing resources in network devices can be periodically allocated to terminal devices. Without a release mechanism, these allocated sensing resources can be wasted when the terminal device no longer needs sensing. This can be particularly problematic if the sensing service frequency is low. For example, when a car parks, sensing resources are no longer needed, so they should be released. Similarly, if a target is completely obstructed, it cannot be measured, and sensing resources can also be released. Dynamic resource allocation is suitable for triggering temporary sensing services, offering greater flexibility but leading to higher signaling overhead. Reducing dynamic signaling overhead and improving resource utilization are the issues addressed in this case.

[0135] To address the aforementioned issues, this disclosure proposes a perceptual scheduling method that can reduce dynamic signaling overhead and improve resource utilization. The specific details of this method are shown below.

[0136] Figure 2 is an interactive schematic diagram of the sensing scheduling method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a sensing scheduling method for a communication system 100. The communication system 100 may include a first device 101 and a second device 102. The method includes:

[0137] Step 2101a: The first device determines the first resource window.

[0138] In some embodiments, the first device may determine a first resource window, which is used for sensing between the first device and the second device. The first resource window includes at least one of a second resource window and a third resource window. The second resource window is used to preempt the third resource window. The third resource window is used for the first device to send a sensing signal to the second device or for the second device to receive a sensing signal sent by the first device.

[0139] In some embodiments, the first resource window can be a perception window, the second resource window can be a preemption window, and the third resource window can be a service window. The temporal length of the second resource window is no longer than that of the first resource window, and the temporal length of the third resource window is no longer than that of the first resource window.

[0140] In some embodiments, the name of the first resource window is not limited, and it can be "Perception Window", "Perception Resource", "Perception Resource Block", "Perception Resource Window", etc. The name of the second resource window is not limited, and it can be "Preemption Window", "Preemption Resource", "Preemption Resource Block", "Resource Preemption Window", "Perception Resource Preemption Window", etc. The name of the third resource window is not limited, and it can be "Business Window", "Business Resource", "Business Resource Block", "Perception Business Window", "Perception Business Resource", etc.

[0141] In some embodiments, determining the first resource window includes: determining the parameters of the first resource window based on protocol predefined parameters; or determining the parameters of the first resource window based on configuration signaling of the network device. Specifically, when the first device is a network device, the network device can determine the parameters of the first resource window based on protocol predefined parameters; when the first device is a terminal, the terminal can determine the parameters of the first resource window based on protocol predefined parameters or configuration signaling of the network device.

[0142] In some embodiments, determining a first resource window may include determining a second resource window and determining a third resource window.

[0143] In some embodiments, the configuration method for the parameters of the first resource window configured by the network device may include a semi-static or dynamic method. The configuration signaling may be any downlink signaling, such as at least one of core network signaling, Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (CE) signaling, and Downlink Control Information (DCI) signaling. For example, the first device is a terminal, which can receive RRC signaling sent by the network device and determine the parameters of the first resource window based on the configuration parameters in the RRC signaling.

[0144] In some embodiments, the first resource window includes at least one of the following parameters:

[0145] The first time domain starting point is used to indicate the time domain starting point of the first resource window;

[0146] The first time domain endpoint is used to indicate the time domain endpoint of the first resource window;

[0147] The first time domain length is used to indicate the time domain length of the first resource window or the number of consecutive time domain resource units;

[0148] The first number indicates the number of the first resource windows;

[0149] The first time-domain pattern is used to indicate the pattern of N consecutive first resource windows;

[0150] The first cycle is used to indicate the time period of one or more first resource windows;

[0151] The first frequency domain start point is used to indicate the start point of the frequency domain resource corresponding to the first resource window;

[0152] The first frequency domain endpoint is used to indicate the endpoint of the frequency domain resource corresponding to the first resource window;

[0153] The first frequency domain length is used to indicate the length of the frequency domain resource corresponding to the first resource window or the number of frequency domain resource units;

[0154] The first frequency domain pattern is used to indicate the pattern of the frequency domain resources corresponding to the first resource window.

[0155] Specifically, the first time-domain pattern can indicate the pattern of N consecutive first resource windows through a bitmap. Each first time-domain pattern can include a bitmap. For example, consecutive bit values ​​with the same bit value can represent a sensing window, such as 100111000, indicating 4 sensing windows with time-domain lengths of 1 time-domain unit (one 1), 2 time-domain units (two 0s), 3 time-domain units (three 1s), and 3 time-domain units (three 0s).

[0156] Specifically, the first frequency domain pattern can indicate the pattern of the frequency domain resources corresponding to the first resource window through a bit map. Each first frequency domain pattern can include a bit map, for example, 10011100, indicating that the resources in the eight frequency domain units are available in the first, fourth, fifth, and sixth frequency domain units.

[0157] In some embodiments, the second resource window includes at least one of the following parameters:

[0158] The second time domain start point is used to indicate the time domain start point of the second resource window;

[0159] The second time domain endpoint is used to indicate the time domain endpoint of the second resource window;

[0160] The second time domain length is used to indicate the time domain length of the second resource window or the number of consecutive time domain resource units.

[0161] In some embodiments, the third resource window includes at least one of the following parameters:

[0162] The third time domain starting point is used to indicate the time domain starting point of the third resource window;

[0163] The third time domain endpoint is used to indicate the time domain endpoint of the third resource window;

[0164] The third time domain length is used to indicate the time domain length of the third resource window or the number of consecutive time domain resource units.

[0165] In some embodiments, this step is optional, and can be omitted (or not omitted) when the second device can determine the first resource window. In other words, the first device and the second device, as transceivers of the sensing signal, can determine the first resource window separately, or they can determine it independently, and this disclosure does not limit this.

[0166] Step 2101b: The second device determines the first resource window.

[0167] In some embodiments, the second device may determine a first resource window, which is used for sensing between the first device and the second device. The first resource window includes at least one of a second resource window and a third resource window. The second resource window is used to preempt the third resource window. The third resource window is used for the first device to send a sensing signal to the second device or for the second device to receive a sensing signal sent by the first device.

[0168] Optionally, the method by which the second device determines the first resource window is the same as the method by which the first device determines the first resource window, and can be referred to in step 2101a, which will not be repeated here.

[0169] In some embodiments, this step is optional, and can be omitted (or not omitted) when the first device can determine the first resource window. In other words, the first device and the second device, as transceivers of the sensing signal, can determine the first resource window separately, or they can determine it individually, and this disclosure does not limit this.

[0170] Step 2102a: The first device determines that the third resource window is idle.

[0171] In some embodiments, if the first device does not detect a wireless signal in the second resource window, it determines that the third resource window is idle.

[0172] In other words, the first device can determine that the third resource window is idle under the first condition, wherein the first condition is that the first device detects that there is no wireless signal transmission in the second resource window.

[0173] Specifically, the first device can detect whether the second resource window is transmitting a wireless signal. For example, it can determine whether the third resource window is idle by detecting whether the second resource window has radio frequency energy.

[0174] In other words, when there is no energy to send in the second resource window, it can be determined that the third resource window is idle. That is, when there is no energy to send in the preemption window, it can be determined that the service window is currently idle. In other words, the first device can determine that no other device is preempting the service window, and at this time, it can perform sensing in the third resource window (service window).

[0175] In some embodiments, this step is optional and can be omitted when the second device can determine that the third resource window is idle.

[0176] Step 2102b: The second device determines that the third resource window is idle.

[0177] In some embodiments, the second device determines that the third resource window is idle when it does not detect a wireless signal in the second resource window.

[0178] In other words, the second device can determine that the third resource window is idle under the first condition, wherein the first condition is that the second device detects that there is no energy transmission in the second resource window.

[0179] Specifically, the method by which the second device determines that the third resource window is idle is the same as the method by which the first device determines that the third resource window is idle, and can be referred to step 2102a, which will not be repeated here.

[0180] In some embodiments, this step is optional and can be omitted when the first device can determine that the third resource window is idle. In other words, when the first device and / or the second device determine the first resource window, the first device can determine whether the third resource window is idle, and the second device can also determine whether the third resource window is idle. That is, both the transmitting and receiving ends of the sensing signal can determine whether the service window has been preempted, and both can preempt the service window if it has not been preempted.

[0181] Step 2103a: The first device preempts the third resource window.

[0182] In some embodiments, it can be determined that the first device has a need for sensing services, and continuously send a first signal in the second resource window to preempt the third resource window.

[0183] In other words, if the first device has a need for sensing services, the first device can continuously send the first signal in the second resource window in order to seize the third resource window.

[0184] For example, the first signal can be a preemption signal, which can be used to preempt the third resource window. In other words, the first signal can be continuously sent during the preemption window to preempt the third resource window.

[0185] In this embodiment, the name of the first signal is not limited; it can be a "preemption signal", "service window preemption signal", "sensing preemption signal", etc.

[0186] In some embodiments, the first device may preempt the third resource window when the third resource window is idle, and may not preempt the third resource window when the third resource window is occupied or not idle.

[0187] In some embodiments, the first device can preempt the third resource window if it has already been occupied by another device (the third resource window is not idle), and resolve which device will use the third resource window for sensing services through a conflict resolution mechanism.

[0188] Understandably, the same resource window can be configured for multiple devices, and multiple devices can compete for the resource window, but it can only be used by a pair of devices (the receiving device and the sending device) at the same time.

[0189] In some embodiments, this step is optional and can be omitted when the second device can preempt the third resource window.

[0190] Step 2103b: The second device preempts the third resource window.

[0191] In some embodiments, it can be determined that the second device has a sensing service demand, and continuously send a first signal in the second resource window to preempt the third resource window.

[0192] In other words, if the second device has a need for sensing services, the second device can continuously send the first signal in the second resource window in order to seize the third resource window.

[0193] Specifically, the method by which the second device preempts the third resource window is the same as the method by which the first device preempts the third resource window, as can be found in step 2103a, and will not be repeated here.

[0194] In some embodiments, this step is optional and can be omitted when the first device can preempt the third resource window.

[0195] Step 2104: The first device sends a second signal to the second device.

[0196] In some embodiments, the second signal may be used to indicate that the third resource window has been preempted by the first device and / or to indicate that the second device receives a sensing signal in the third resource window.

[0197] Specifically, after the first device seizes the third resource window, it can send a second signal to the second device to notify the second device that the third resource window has been seized by the first device, or to indicate to the second device that it can receive a sensing signal in the resource window.

[0198] In some embodiments, the second signal may include an identifier indicating successful preemption and an identifier and / or parameters of the preempted third resource window.

[0199] In some embodiments, the name of the second signal is not limited, and it may be a "preemption confirmation message", "notification message", "preemption success message", etc.

[0200] In some embodiments, this step is optional. When the second device preempts the third resource window, the second device can send a third signal to the first device to notify it. In this case, this step can be omitted.

[0201] Step 2105: The second device sends a third signal to the first device.

[0202] In some embodiments, the third signal may be used to indicate that the third resource window has been preempted by the second device and / or to indicate that the first device sends a sensing signal in the third resource window.

[0203] Specifically, after the second device seizes the third resource window, it can send a third signal to the first device to notify the first device that the third resource window has been seized by the second device, or it can be used to instruct the first device to send a sensing signal in the resource window.

[0204] In some embodiments, the third signal may include at least one of the following: an identifier of preemption failure, an identifier and / or parameters of the preempted third resource window, which device preempted the third resource window, and the time when the third resource window was released.

[0205] In some embodiments, the name of the second signal is not limited, and it may be a "preemption confirmation message", "notification message", "preemption success message", etc.

[0206] In some embodiments, this step is optional. When the first device preempts the third resource window, the first device can send a second signal to the second device to notify it. In this case, this step can be omitted.

[0207] Step 2106: The first device sends a sensing signal to the second device.

[0208] In some embodiments, the first device can send sensing signals to the second device through a third resource window to complete the sensing service.

[0209] Depending on the differences between the first and second devices, the sensing services can be completed in the following specific ways.

[0210] Method 1

[0211] When both the first and second devices are network devices, the first device can determine that the third resource window is idle. Then, the first device sends a first signal in the second resource window to preempt the third resource window. The first device then sends a second signal to the second device to notify and / or instruct the second device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0212] Method 2

[0213] When both the first and second devices are network devices, the second device can determine that the third resource window is idle. Then, the second device sends a first signal in the second resource window to preempt the third resource window. The second device then sends a third signal to the first device to notify and / or instruct the first device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0214] Method 3

[0215] When the first device is a terminal and the second device is a network device, the first device can determine that the third resource window is idle, and then send a first signal in the second resource window to preempt the third resource window. The first device sends a second signal to the second device to notify and / or instruct the second device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0216] Method 4

[0217] When the first device is a terminal and the second device is a network device, the second device can determine that the third resource window is idle, and then send a first signal in the second resource window to preempt the third resource window. The second device sends a third signal to the first device to notify and / or instruct the first device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0218] Method 5

[0219] When the first device is a network device and the second device is a terminal, the first device can determine that the third resource window is idle, and then send a first signal in the second resource window to preempt the third resource window. The first device sends a second signal to the second device to notify and / or instruct the second device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0220] Method 6

[0221] When the first device is a network device and the second device is a terminal, the second device can determine that the third resource window is idle, and then send a first signal in the second resource window to preempt the third resource window. The second device sends a third signal to the first device to notify and / or instruct the first device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0222] Method 7

[0223] When both the first and second devices are terminals, the first device can determine that the third resource window is idle. Then, the first device sends a first signal to the second resource window to preempt the third resource window. The first device then sends a second signal to the second device to notify and / or instruct the second device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0224] Method 8

[0225] When both the first and second devices are terminals, the second device can determine that the third resource window is idle. Then, the second device sends a first signal in the second resource window to preempt the third resource window. The second device then sends a third signal to the first device to notify and / or instruct the first device. After that, the first device can send a sensing signal to the second device in the third resource window to complete the sensing service.

[0226] Method 9

[0227] For example, the first device and the second device can be the same device, such as a terminal transmitting and receiving data on its own, or a network device transmitting and receiving data on its own, etc. In this case, after determining that the third resource window is idle, the device can send the first signal in the second resource window to seize the third resource window, and send a sensing signal in the third resource window to complete the sensing service.

[0228] Step 2107a: The first device releases the third resource window.

[0229] In some embodiments, releasing a third resource window includes:

[0230] Stop sending the first signal in the second resource window; or send the fourth signal in the fourth resource window, where the first resource window also includes the fourth resource window, and the fourth signal is used to indicate the release of the third resource window.

[0231] In other words, the first device can release the third resource window by stopping sending the first signal, or it can release the third resource window by a separate release signal.

[0232] For example, if a first device preempts a third resource window by sending a first signal in a second resource window, the first device can release the third resource window by stopping sending the first signal. When the first signal is stopped being sent in the second resource window (preempted window), it can be indicated that the third resource window has been released.

[0233] For example, when the first device sends a fourth signal in the fourth resource window, it can indicate that the third resource window is being released. The first device can be the device that preempted the third resource window; that is, whoever preempts releases it. Alternatively, the second device can be the device that preempted the third resource window, and the first device instructs the second device to release the third resource window via the fourth signal.

[0234] For example, the device that preempts the third resource window can perform the operation of releasing the third resource window. For instance, when the first device finishes preempting the third resource window, the first device can release the third resource window.

[0235] In some embodiments, the fourth resource window can optionally be a release window, that is, after the sensing service is completed, the third resource window can be released in the fourth resource window, which can facilitate other devices to use the third resource window and improve resource utilization.

[0236] In some embodiments, the fourth resource window includes at least one of the following parameters:

[0237] The fourth time-domain starting point is used to indicate the time-domain starting point of the fourth resource window;

[0238] The fourth time domain endpoint is used to indicate the time domain endpoint of the fourth resource window;

[0239] The fourth time domain length is used to indicate the time domain length of the fourth resource window or the number of consecutive time domain resource units.

[0240] In some embodiments, the fourth signal includes any of the following:

[0241] The first bit in the first bit diagram corresponds to the first transmission opportunity in the third resource window. The first transmission opportunity is the opportunity to send any sensing signal. When the value of the first bit is the first value, the fourth signal indicates that the first transmission opportunity has been released. When the value of the first bit is the second value, the fourth signal indicates that the first transmission opportunity has not been released.

[0242] The second bit in the second bit diagram corresponds to the second transmission opportunity in the third resource window. The second transmission opportunity is the opportunity to transmit a sensing signal that has not collided with other service channels. When the value of the second bit is the first value, the fourth signal indicates that the second transmission opportunity has been released. When the value of the second bit is the second value, the fourth signal indicates that the second transmission opportunity has not been released.

[0243] The first bit is used to indicate whether the first transmission opportunity configured or preempted in the third resource window has been released. When the value of the first bit is the first value, the fourth signal indicates that the first transmission opportunity has been released. When the value of the first bit is the second value, the fourth signal indicates that the first transmission opportunity has not been released.

[0244] The second bit is used to indicate whether the second transmission opportunity configured or preempted in the third resource window has been released. When the value of the second bit is the first value, the fourth signal indicates that the second transmission opportunity has been released. When the value of the second bit is the second value, the fourth signal indicates that the second transmission opportunity has not been released.

[0245] In other words, the fourth signal can use the first bit map to indicate that the third resource window has been released. Each bit in the first bit map can correspond to a first transmission timing, where the first transmission timing can be the transmission timing of the sensing resource. That is, each bit in the first bit map can correspond to a transmission timing of the sensing resource. When the value of the first bit is a first value, it can indicate that the resource corresponding to the first transmission timing has been released. When the value of the first bit is a second value, it can indicate that the resource corresponding to the first transmission timing has not been released. Specifically, the first value can be 1 or 0, and the second value can be 0 or 1. This disclosure does not limit this.

[0246] In other words, the fourth signal can use the second bit map to indicate that the third resource window has been released. Each bit in the second bit map can correspond to a second transmission opportunity. The second transmission opportunity can be the time when a sensing signal that has not collided with other service channels is transmitted, that is, the effective transmission opportunity of the sensing resource. When the value of the second bit is the first value, it can indicate that the resource corresponding to the second transmission opportunity has been released. When the value of the second bit is the second value, it can indicate that the resource corresponding to the second transmission opportunity has not been released. Specifically, the first value can be 1 or 0, and the second value can be 0 or 1. This disclosure does not limit this.

[0247] In other words, the fourth signal can use the first bit to indicate that the third resource window has been released. When the value of the first bit is the first value, it can indicate that the first transmission opportunity has been released. When the value of the first bit is the second value, it can indicate that the first transmission opportunity has not been released. At this time, the first transmission opportunity can be the transmission opportunity of the most recently configured or preempted sensing resource. Specifically, the first value can be 1 or 0, and the second value can be 0 or 1. This disclosure does not limit this.

[0248] In other words, the fourth signal can use the second bit to indicate that the third resource window has been released. When the value of the second bit is the first value, it can indicate that the second transmission opportunity has been released. When the value of the second bit is the second value, it can indicate that the second transmission opportunity has not been released. At this time, the second transmission opportunity can be the most recently configured or preempted valid transmission opportunity of the sensing resource. Specifically, the first value can be 1 or 0, and the second value can be 0 or 1. This disclosure does not limit this.

[0249] In some embodiments, this step is optional. When the second device preempts the third resource window, the second device can release the third resource window. In this case, this step can be omitted.

[0250] Step 2107b: The second device releases the third resource window.

[0251] In some embodiments, for example, the device that preempts the third resource window may perform the operation of releasing the third resource window. For instance, when the second device finishes preempting the third resource window, the second device may release the third resource window.

[0252] Specifically, the method by which the second device releases the third resource window is the same as the method by which the first device releases the third resource window, and can be found in step 2107a. This disclosure does not limit this method.

[0253] In some embodiments, this step is optional. When the first device preempts the third resource window, the first device can release the third resource window. In this case, this step can be omitted.

[0254] It is understandable that either the transceiver of the sensing signal (the first device or the second device) can preempt the third resource window or release the resource window, including: the first device preempts and releases the third resource window, the second device preempts and releases the resource window, the first device preempts the resource window and the second device releases the resource window, and the second device preempts the resource window and the first device releases the resource window.

[0255] The method involved in the embodiments of this disclosure may include at least one of steps 2101a to 2107b. For example, step 2101(2101a or 2101b)+2102(2102a or 2102b)+2103(2103a or 2103b)+2104+2106+2107(2107a or 2107b) can be implemented as an independent embodiment, step 2101(2101a or 2101b)+2102(2102a or 2102b)+2103(2103a or 2103b)+2105+2106+2107(2107a or 2107b) can be implemented as an independent embodiment, and step 2101+2102+2103+2105 can be implemented as an independent embodiment, but is not limited thereto.

[0339] The following is an exemplary description of the above method.

[0340] The method illustrated in this disclosure relates to a design approach suitable for sensing service scheduling.

[0341] The method will be explained and illustrated below through specific examples.

[0342] The method in this example allows you to configure resources in two ways, as detailed below.

[0343] Method 1: Introducing a contention mechanism, the UE monitors the public sensing resources configured by the base station through Sensing Listen Before Talk (S-LBT). The occupancy window needs to limit the time of each occupancy. Unlike NRU, it can adopt an on-demand occupancy approach.

[0344] Method 2: Semi-static configuration of resources for each UE, with periodic configuration. A further mechanism, Unused Transmission Sensing Occasion (UTSO), is introduced to release unused uplink unlicensed configuration grant (CG) resources. Unlike R18 XR, UTO can be monitored by the UE; if the UE detects it, it considers the CG to have been released to the public resource pool.

[0345] The above method will be explained and illustrated with specific examples below.

[0346] Example 1

[0348] The protocol predefines at least one of the following: a perception window, a preemption window, a service window, and a release window. The configuration methods for the perception window, preemption window, service window, and release window can be semi-static or dynamic, i.e., include at least one of the following: core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration.

[0355] The perceptron window pattern is used to indicate N consecutive perceptron windows. The perceptron window pattern includes a bitmap, where consecutive bits with the same value represent a perceptron window. For example, 100111000 indicates 4 perceptron windows with time domain lengths of 1 time domain unit (one 1), 2 time domain units (two 0s), 3 time domain units (three 1s), and 3 time domain units (three 0s).

[0362] Furthermore, the configuration parameters for the preemption window are determined to include at least one of the following: the preemption window time domain start point, the preemption window time domain end point, and the preemption window length. These parameters are predefined by the protocol, as follows:

[0363] The preemption window time domain start point is used to indicate the time domain start point of the preemption window.

[0364] The preemption window time domain endpoint is used to indicate the time domain endpoint of the preemption window.

[0365] The preemption window length indicates the temporal length of the preemption window, or the number of consecutive temporal resource units.

[0366] A service window refers to a resource window within a service window that can be used to perceive services.

The configuration parameters of the service window include at least one of the following: service window time domain start point, service window time domain end point, and service window length.

The first signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0367] Furthermore, the configuration parameters for the business window are determined to include at least one of the following: the business window time domain start point, the business window time domain end point, and the business window length. These parameters are predefined by the protocol, as follows:

[0368] The business window time domain start point is used to indicate the time domain start point of the business window.

[0369] The business window time domain endpoint is used to indicate the time domain endpoint of the business window.

[0370] The business window length indicates the time domain length of the business window, or the number of consecutive time domain resource units.

[0371] A release window refers to a resource window within which window release signaling can be sent. The time domain length of the release window is no longer than the perception window. The first device includes at least one of network devices and terminal devices. The configuration parameters of the release window include at least one of the following: release window time domain start point, release window time domain end point, and release window length.

Then, network device A sends the sensing signal within its service window, and network device B receives the sensing signal at the corresponding location, thus completing the sensing service.

[0384] Example 2

[0385] In a network, network devices and terminal devices jointly perform sensing services. Sensing services can be transmitted and received in licensed spectrum or in unlicensed spectrum. The transmission and reception methods of sensing signals include at least one of the following: network device self-transmission and reception, network device A transmitting and network device B receiving, terminal device transmitting and network device receiving, network device transmitting and terminal device receiving, terminal device self-transmission and reception, and terminal device A transmitting and terminal device B receiving. Network devices include at least one of base station equipment and core network equipment.

[0386] The sensing resources are configured by the network devices. The configured sensing resources can only be used by the terminal devices to send and / or receive sensing signals, or the configured sensing resources can only be used by the terminal devices and the network devices to send and / or receive sensing signals.

[0387] The first device is configured with sensing resources, or the first device successfully preempts sensing resources. The first device includes at least one of a terminal device and a network device. When the first device wants to release sensing resources, it needs to send a first signaling message. The first signaling message is used by the first device to release the corresponding sensing resources.

[0388] 1. The first signaling contains a bitmap, with each bitmap corresponding to the transmission timing of a sensed resource. The first value of the bit indicates that the corresponding resource has been released, and the second value of the bit indicates that the corresponding resource has not been released.

[0389] 2. The first signaling instruction contains a bitmap, each bitmap corresponding to a valid transmission opportunity for a sensed resource. A valid transmission opportunity refers to a transmission opportunity that does not collide with other service channels. The first value of the bit indicates that the corresponding resource has been released, and the second value of the bit indicates that the corresponding resource has not been released. Furthermore, a valid transmission opportunity refers to a transmission opportunity that does not conflict with any other signal / channel.

[0390] 3. The first signaling bit contains one bit, which indicates whether the transmission timing of the most recently configured / preempted sensed resource has been released. The first value of the bit indicates that the corresponding resource has been released, and the second value of the bit indicates that the corresponding resource has not been released.

[0391] 4. The first signaling bit contains one bit indicating whether the valid transmission opportunity for the most recently configured / preempted sensed resource has been released. The first value of the bit indicates that the corresponding resource has been released, and the second value of the bit indicates that the corresponding resource has not been released. Furthermore, a valid transmission opportunity refers to a transmission opportunity that does not conflict with any other signals / channels.

[0392] In one implementation, the base station configures shared sensing resources for multiple UEs, and the UEs use the transmission opportunities corresponding to the sensing resources through a contention mechanism. When a UE successfully preempts a sensing resource and finishes using it, it sends a first signaling message containing one bit to indicate whether the transmission opportunity of the sensing resource has been released.

[0393] In one implementation, the base station configures common sensing resources for a specific UE. When the UE finishes using the resources, it sends a first signaling message containing one bit indicating whether the transmission timing of the sensing resources has been released.
