[0225] In some embodiments, Integrated Sensing and Communication (ISAC) is a novel technology designed to integrate sensing capabilities into the design of a communication system, enabling the system to provide sensing as a service along with communication to the user.
[0226] In some embodiments, the ISAC system needs to consider both communication and sensing service requirements during the design process.
[0227] In some embodiments, ISAC technology mainly includes the following two sensing modes:
[0228] In the mono-static mode, the same node sends and receives the sensing signals.
[0229] In bi-static mode, the nodes that send and receive sensing signals are different.
[0230] In some embodiments, please refer to Figure 1b, which illustrates a schematic diagram of wireless sensing modes. These modes are further divided into six modes based on the type of sensing transmitter and receiver.
[0231] Mode 1: Base station self-transmitting and self-receiving mode (i.e., Transmission Reception Point (TRP) mono-static mode). The base station sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected or scattered waves.
[0232] Mode 2: Base station A transmits and B receives (i.e., TRP-TRP bi-static). 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 or scattered waves.
[0233] Mode 3: Terminal transmits, base station receives (i.e., UE-TRP bi-static). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected or scattered waves.
[0234] Mode 4: Base station transmits, terminal receives (TRP-UE bi-static). The base station transmits a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected or scattered wave.
[0235] Mode 5: Terminal mono-static (UE) mode. The terminal sends a sensing signal, which is then received and measured after passing through the environment or objects in the environment.
[0236] Mode 6: Terminal A transmits and Terminal B receives (i.e., UE-UE bis-tatic). Terminal A transmits a sensing signal, which passes through the environment or objects in the environment, and Terminal B receives and measures the reflected or scattered waves.
[0237] In some embodiments, when sensing a target based on wireless signals, the process typically involves directly measuring the wireless signal reflected by the target to obtain information such as the time delay, angle, and Doppler frequency of its multipath components, thereby determining the target's position and other parameters. To improve the accuracy of target sensing, it is generally necessary to combine the measurement results from multiple pairs of sensing transmitters and receivers to obtain the target sensing results, including time delay, Doppler frequency, and angle. The sensing receiver measures the configured sensing signal and reports the measurement results to the Sensing Function (SF) entity.
[0238] In some embodiments, information such as the time delay, Doppler frequency, and / or angle of the sensed target is obtained based on measurements of the sensed signal reflected from the sensed target. Changes in environmental multipath components caused by the sensed target are generally treated as interference or noise. In reality, these changes in environmental multipath components are caused by the sensed target and also carry information about the sensed target.
[0239] In some embodiments, this disclosure proposes to combine direct measurement of the reflected signal of the sensing target with measurement of changes in the environmental multipath component, thereby improving the sensing performance of the sensing target.
[0240] In some embodiments, a pair of sensing transmitters (STX) and sensing receivers (SRX) are employed. When sensing a target (hereinafter referred to as the target), the STX transmits a sensing signal, such as a reference signal for sensing operations, and the SRX receives the sensing signal. The SRX can detect multipath components in the received sensing signal. Different multipath components differ from other multipath components in at least one of the following aspects: time delay, angle, and Doppler frequency. In addition, the intensity of each multipath, i.e., the received power, is also an important parameter. The above multipath parameters, i.e., time delay, angle, Doppler frequency, and intensity, reflect the characteristics of the sensing target in the area. Further, to improve the accuracy of sensing, multiple STXs and / or SRXs can be configured to sense the same target. The measurement results of the SRXs are jointly processed by the Sensing Function (SF) to obtain the target's location and characteristic information. The SF can be located in the core network or in the Radio Access Network (RAN). In particular, the SF can be one of the STXs or SRXs that perform the sensing operations described above.
[0241] In some embodiments, please refer to Figure 1c, which illustrates a schematic diagram of the influence of a sensed target on the environment. The presence and movement of the sensed target will interact with the wireless signal propagation of environmental objects. Figure 1c is a schematic diagram of the interaction between the sensed target and the environment. In Figure 1c, E, E1, E2, E3, and E4 represent environmental objects, and T1, T2, T3, and T4 represent sensed targets.
[0242] In some embodiments, the interaction between the perceived target and environmental objects may include one or more of the following situations (corresponding to the various examples below):
[0243] For example, the presence and movement of a sensed target may block or weaken a wireless signal transmitted from an STX (Sensor Transport) to an environmental object, causing the environmental object to become invisible or have a weaker signal at the SRX (Sensor Receiver). For instance, in Figure 1c, the wireless signal from the STX to the environmental object E1 is blocked by the sensed target T1.
[0244] For example, the presence and movement of a sensed target may block or weaken the wireless signal reflected from an environmental object to the SRX, causing the environmental object to become invisible or have a weaker signal at the SRX. For instance, in Figure 1c, the wireless signal from environmental object E2 to the SRX is blocked by sensed target T1.
[0245] For example, due to the presence and movement of the sensed target, an environmental object may block or weaken the wireless signal from STX to the sensed target, causing the sensed target to become invisible or the signal to weaken at SRX. For instance, in Figure 1c, the wireless signal from STX to sensed target T2 is blocked by environmental object E3.
[0246] For example, due to the presence and movement of the sensed target, an environmental object may block or weaken the wireless signal reflected from the sensed target to the SRX, causing the sensed target to become invisible or have a weaker signal at the SRX. For instance, the wireless signal reflected from the sensed target T3 to the SRX in Figure 1c is blocked by the environmental object E4.
[0247] For example, the presence and movement of a sensed target may block or weaken the wireless signal from STX to SRX, meaning that SRX detects STX as invisible or the signal as weak. For instance, in Figure 1c, the wireless signal from STX to SRX is blocked by the sensed target T4.
[0248] For example, due to the presence and movement of the sensed target, some of the wireless signals reflected by the sensed target may reach an environmental object, causing the wireless signal reflected from this environmental object to the SRX to become stronger. Because the path from the STX to the sensed target to the environmental object is not a line-of-sight (LOS), i.e., its delay is greater than that of the line-of-sight from the STX to the environmental object, the SRX may be able to distinguish the increased wireless signal, i.e., the new path reflected to the SRX, from the delay characteristics.
[0249] For example, the wireless signal of the environmental object E at the SRX is not affected by the perceived target.
[0250] For example, the wireless signal of the sensing target T1 at the SRX is not affected by environmental objects.
[0251] In some embodiments, when multiple STXs or multiple SRXs are present in the region, the impact of the presence and movement of the sensed target is generally different for different pairs of STXs and SRXs. The aforementioned impact on environmental objects and / or the received signals of STXs at SRXs due to the presence and movement of the sensed target can be used to assist in the sensing operation of the sensed target.
[0252] Figure 2a is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure relates to a communication method for a communication system 100, the method comprising:
[0253] Step S2101: The second device sends the first information to the first device.
[0254] In some embodiments, the first device receives first information sent by the second device.
[0255] In some embodiments, the first device is a device for performing sensing.
[0256] In some embodiments, the first device is a transmitting device (e.g., a sensing transmitter STX) and / or a receiving device (e.g., a sensing receiver SRX) for performing sensing.
[0257] In some embodiments, the second device is the entity that sends the first information, such as a Sensing Function (SF). The SF can be located in the core network or the access network, and there is no limitation thereto. It should be noted that in some scenarios, the SF can also be the STX or SRX itself. In this scenario, since the SF is the STX or SRX itself, step S2101 may not be performed. For example, the SF will be used to represent the second device below.
[0258] It should be noted that the perception results obtained by the first device, after being processed by SF, can yield the location and feature information of the perceived target.
[0259] In some embodiments, the first information is used to indicate a perceived resource.
[0260] In some embodiments, the sensing resources are used to send and / or receive sensing signals. It should be noted that the first device needs to send and / or receive sensing signals during the sensing process. When the first device is a transmitting device for sensing, it sends sensing signals; when the first device is a receiving device for sensing, it receives sensing signals.
[0261] For example, a pair of sensing transmitters (STX) and sensing receivers (SRX) are used. When sensing a target (which may be simply referred to as the target), the STX sends a sensing signal, such as a reference signal for sensing operations, and the SRX receives the sensing signal.
[0262] In some embodiments, multiple STXs and / or SRXs can be configured to sense the same target, which can improve the accuracy of sensing.
[0263] In some embodiments, the sensing signal includes a first sensing signal and / or a second sensing signal.
[0264] In some embodiments, the first sensing signal is a signal sent toward the sensing target or a signal received from the sensing target.
[0265] In some embodiments, when the first device is a transmitter, the first sensing signal is a signal sent in the direction of the sensing target.
[0266] For example, if the first sensing signal is a signal sent by the first device, and the sensing target is located in direction A relative to the first device, then the first sensing signal is a signal sent in direction A.
[0267] In some embodiments, when the first device is a receiver, the first sensing signal is a signal received from the direction of the sensing target.
[0268] For example, if the first sensing signal is a signal received by the first device, and the sensing target is located in direction B of the first device relative to the first device, then the first sensing signal is a signal received from direction B.
[0269] In some embodiments, the first sensing signal is a signal positioned in the direction of the sensing target. In some embodiments, the second sensing signal is a signal sent toward or received from the direction of the environmental object.
[0270] In some embodiments, when the first device is the transmitter, the second sensing signal is a signal sent in the direction of the environmental object.
[0271] For example, if the first sensing signal is a signal sent by the first device, and the environmental object is located in the C direction relative to the first device, then the first sensing signal is a signal sent in the C direction.
[0272] In some embodiments, when the first device is a receiver, the second sensing signal is a signal received from the direction of an environmental object.
[0273] For example, if the first sensing signal is a signal received by the first device, and the environmental object is located in direction D relative to the first device, then the first sensing signal is a signal received from direction D.
[0274] In some embodiments, the second sensing signal is a signal positioned relative to the direction of an environmental object. In some embodiments, the first information includes at least one of the following:
[0275] Information about time resources (which can also be understood as information about time-domain resources);
[0276] Information about frequency resources (which can also be understood as information about frequency domain resources);
[0277] Beam information (which can be indicated by an index number; different beams correspond to different directions);
[0278] Information on transmission power (transmission power can be the power used to send sensing signals).
[0279] In some embodiments, the transmitting end (or transmitting device) for sensing and the receiving end (or receiving device) for sensing satisfy the following: the information of the time resources used is the same as the information of the frequency domain resources used, but the beam information is different.
[0280] In some embodiments, the sensing resource is a resource configured for a sensing target. For example, sensing resource A is used to sense the sensing target a.
[0281] In some embodiments, the sensing resource is a resource set up for at least two of the sensing targets. For example, sensing resource B is used to sense sensing target b and sensing target c.
[0282] In some embodiments, the first device is a transmitter of a sensing signal; the sensing resources include a first sensing resource and a second sensing resource, the first sensing resource is used to transmit the first sensing signal, the second sensing resource is used to transmit the second sensing signal, and the first sensing resource and the second sensing resource may be the same or different.
[0283] In some embodiments, when the relative positional relationship between the sensing target, the environmental object, and the transmitting end is a first relative positional relationship, the first sensing resource is the same as the second sensing resource.
[0284] In some embodiments, when the relative positional relationship between the sensing target, the environmental object, and the transmitting end is a second relative positional relationship, the first sensing resource and the second sensing resource are not the same.
[0285] In some embodiments, the first relative positional relationship and / or the second relative positional relationship are determined based on the distance and / or orientation between the sensing target, the environmental object, and the transmitting end. Here, orientation includes direction and / or location.
[0286] In some embodiments, please refer to Figure 6a. Relative to the transmitting end STX, the sensing target T and the environmental object E1 are in the same direction or close to each other. The relative positional relationship between the sensing target T, the environmental object E1 and the transmitting end STX is the first relative positional relationship.
[0287] In some embodiments, please refer to Figure 6a. The same or similar direction can be: the angle formed by the line connecting T to the transmitter STX (solid line in Figure 6a) and the line connecting E1 to the transmitter (dashed line in Figure 6a) is less than or equal to the angle threshold. Here, the angle threshold can be preset according to actual needs, for example, it can be set to x degrees.
[0288] In some embodiments, when the angle is less than or equal to an angle threshold, T and E1 can be covered by the same beam, and the signal transmitted for T and the signal transmitted for E1 can use the same beam resource, for example, beam 1.
[0289] In some embodiments, please refer to Figure 6b. Relative to the transmitting end STX, the sensing target T and the environmental object E2 are not in the same direction or in a similar direction. The relative positional relationship between the sensing target T, the environmental object E2 and the transmitting end STX is the second relative positional relationship.
[0290] In some embodiments, referring to Figure 6b, directions that are not in the same direction or close to each other can be: the angle formed by the line connecting T to the transmitting end STX (solid line in Figure 6b) and the line connecting E2 to the transmitting end STX (dashed line in Figure 6b) is greater than an angle threshold. Here, the angle threshold can be preset according to actual needs, for example, it can be set to y degrees. x and y can be equal or unequal.
[0291] In some embodiments, when the angle is greater than an angle threshold, T and E2 cannot be covered by the same beam. The signal transmitted for T and the signal transmitted for E2 can use different beam resources. For example, beam 1 can be used for T, and beam 2 can be used for E2. In some embodiments, if the first sensing resource is the same as the second sensing resource, the direction of the beam contained in the first sensing resource is the same as the direction of the beam contained in the second sensing resource.
[0292] In some embodiments, the first device is a receiver of a sensing signal; the sensing resources include a third sensing resource and a fourth sensing resource, the third sensing resource is used to receive the first sensing signal, the fourth sensing resource is used to receive the second sensing signal, and the third sensing resource may be the same as or different from the fourth sensing resource.
[0293] In some embodiments, when the relative positional relationship between the sensing target, the environmental object, and the receiving end is a third relative positional relationship, the third sensing resource is the same as the fourth sensing resource.
[0294] In some embodiments, when the relative positional relationship between the sensing target, the environmental object, and the receiving end is a fourth relative positional relationship, the third sensing resource is different from the fourth sensing resource.
[0295] In some embodiments, the third relative position and / or the fourth relative position are determined based on the distance and / or orientation between the sensing target, the environmental object and the receiver.
[0296] In some embodiments, please refer to Figure 6b. Relative to the receiving end SRX, the sensing target T and the environmental object E2 are in the same direction or close to each other. The relative positional relationship between the sensing target T, the environmental object E2 and the receiving end SRX is a third relative positional relationship.
[0297] For example, in some embodiments, please refer to FIG6b. The same direction or a direction close to the same direction can be: the angle formed by the line connecting T to the receiver SRX (solid line in FIG6b) and the line connecting E2 to the receiver SRX (dashed line in FIG6b) is less than or equal to the angle threshold. Here, the angle threshold can be preset according to actual needs, for example, it can be set to z degrees.
[0298] In some embodiments, when the angle is less than or equal to an angle threshold, T and E2 can be covered by the same beam, and the signal received for T and the signal received for E2 can use the same beam resource, for example, beam 1. In some embodiments, referring to Figure 6a, relative to the receiver SRX, the sensing target T and the environmental object E1 are not in the same direction or in a similar direction, and the relative positional relationship between the sensing target, the environmental object E1 and the receiver SRX is a fourth relative positional relationship.
[0299] In some embodiments, referring to Figure 6a, directions that are not in the same direction or close to each other can be: the angle formed by the line connecting T to the receiver SRX (solid line in Figure 6a) and the line connecting E1 to the receiver SRX (dashed line in Figure 6a) is greater than an angle threshold. Here, the angle threshold can be preset according to actual needs, for example, it can be set to n degrees. z and n can be equal or unequal.
[0300] In some embodiments, when the angle is greater than an angle threshold, T and E1 cannot be covered by the same beam. The signals received for T and E1 can use different beam resources. For example, beam 1 can be used for T and beam 2 can be used for E1.
[0301] In some embodiments, the third sensing resource is the same as the fourth sensing resource, and the direction of the beam contained in the third sensing resource is the same as the direction of the beam contained in the fourth sensing resource.
[0302] In some embodiments, the first sensing resource is a third sensing resource.
[0303] In some embodiments, the second sensing resource is a fourth sensing resource.
[0304] It should be noted that in scenarios where the first device obtains the first information through other means, step S2101 is not a necessary step.
[0305] Step S2102: The first device determines the first information.
[0306] In some embodiments, the definition of the first information can be found in step S2101, and will not be repeated here.
[0307] In some embodiments, the first information may be information received from the second device, for example, the first information is the first information in step S2101.
[0308] In some embodiments, the first information may also be information obtained from a higher protocol layer of the first device. In this scenario, step S2101 is not a necessary step.
[0309] Step S2103: The second device sends the second information to the first device.
[0310] In some embodiments, the first device receives second information sent by the second device.
[0311] In some embodiments, the second information is used to indicate the expected result of sensing performed based on the sensing resources. It should be noted that the second information can also be understood as indicating a reference result of sensing performed based on the sensing resources, which can be used to compare with the actual measured result, or to guide sensing operations, such as receiving sensing signals in the direction corresponding to the expected angle.
[0312] In some embodiments, the second information is used to indicate at least one of the following:
[0313] Expected latency of perception;
[0314] The perceived expected Doppler frequency;
[0315] The expected perspective of perception;
[0316] Expected received power.
[0317] In some embodiments, a first type of signal path and a second type of signal path are applied during the sensing process. Here, a signal path may also be referred to as a "path" or a "multipath component". It should be noted that the time delay, angle, Doppler frequency, and / or received power of the signals associated with different types of signal paths may vary.
[0318] In some embodiments, the first type of signal path is a path of a first sensing signal via the sensing target;
[0319] In some embodiments, the second type of signal path is a path influenced by the perceived target and passing through a second perceived signal from an environmental object.
[0320] In some embodiments, being affected by the sensing target can be caused by the second sensing signal transmitted in the direction of the environmental object being blocked or absorbed by the sensing target, resulting in the weakening, disappearance, and / or change of the direction of the second sensing signal. For illustrative purposes, refer to the exemplary embodiments provided in FIG1c above.
[0321] In some embodiments, the first path group includes at least one of the first type of signal paths.
[0322] For example, if there are multiple sensing targets, including a1, a2 and a3, and the corresponding first type of signal paths are L1, L2 and L3 respectively, then the first path group can include L1, L2 and L3.
[0323] In some embodiments, the second path group includes at least one signal path of the second type.
[0324] For example, there are multiple environmental objects, including b1, b2 and b3, and the corresponding second type of signal paths are K1, K2 and K3 respectively. Then the second path group can include K1, K2 and K3.
[0325] In some embodiments, the first path group and / or the second path group are path groups set for one of the sensing targets.
[0326] For example, the first path group is a path group that contains only L1 mentioned above, and the second path group is a path group that contains only K1 mentioned above.
[0327] In some embodiments, the first path group and / or the second path group are path groups set for at least two of the sensing targets.
[0328] For example, the first path group is a path group that includes at least L1 and L2 mentioned above, and the second path group is a path group that includes at least K1 and K2 mentioned above.
[0329] In some embodiments, the second information associated with the first path group and the second path group may be the same or different.
[0330] In some embodiments, the second information associated with the first path group includes a first numerical range corresponding to the expected received power. For example, this can be used for reporting the detection results in step S2106.
[0331] In some embodiments, the second information associated with the second path group includes a second numerical range corresponding to the expected received power. For example, it can be used for reporting the detection results in step S2106.
[0332] In some embodiments, the second information associated with the second path group includes a first range of change corresponding to the expected change in received power.
[0333] It should be noted that in scenarios where the first device obtains the second information through other means, step S2103 is not a necessary step. For example, it can be used for reporting the detection results in step S2106.
[0334] Step S2104: The first device determines the second information.
[0335] In some embodiments, the definition of the second information can be found in step S2103, and will not be repeated here.
[0336] In some embodiments, the second information may be information received from the second device, for example, the second information is the second information in step S2103.
[0337] In some embodiments, the second information may also be information obtained from a higher protocol layer of the first device. In this scenario, step S2103 is not a necessary step.
[0338] Step S2105: The first device performs a sensing operation.
[0339] In some embodiments, the first device performs a sensing operation on a sensing target based on a first type of signal path and a second type of signal path.
[0340] In some embodiments, the signal path associated with the sensing target includes a first type of signal path and a second type of signal path. Because the sensing process uses different types of signal paths, the sensing results are more accurate compared to a single sensing path.
[0341] In some embodiments, the first device transmits a sensing signal on a signal path associated with the sensing target as indicated by the first information to perform a sensing operation for the sensing target.
[0342] In some embodiments, a first device (e.g., a sensing transmitter) transmits a first sensing signal on a first type of signal path and a second sensing signal on a second type of signal path to perform a sensing operation targeting a sensing target. Because sensing signals are transmitted on different types of signal paths during sensing, the obtained sensing results are more accurate.
[0343] In some embodiments, a first device (e.g., a sensing receiver) receives a first sensing signal on a first type of signal path and a second sensing signal on a second type of signal path to perform a sensing operation targeting a sensing target. Correspondingly, the sensing results of the first and second sensing signals can be obtained. Since sensing signals are sent on different types of signal paths during sensing, the obtained sensing results are more accurate.
[0344] In some embodiments, a sensing operation is performed on the sensing target based on the first information and the second information.
[0345] Step S2106: The first device performs the test result reporting.
[0346] In some embodiments, the second information associated with the first path group includes a first numerical range corresponding to the expected first parameter; based on the first numerical range and the magnitude of the first parameter measured in a predetermined direction, the first device performs a report of a first detection result; wherein the first detection result is used to indicate the measurement result of the first type of signal path measured in the predetermined direction.
[0347] In some embodiments, the first parameter is at least one of time delay, Doppler frequency, angle, and / or received power.
[0348] Taking the received power as an example for illustration below, but not limited to the received power, it can also be the time delay, Doppler frequency, angle (which can be the angle of the sensed signal relative to the receiving end), etc.
[0349] In some embodiments, when it is determined that the magnitude of the measured received power is outside the first numerical range, the first device reports the first detection result; the first detection result is used to indicate that the first type of signal path is not measured in a predetermined direction.
[0350] In some embodiments, when it is determined that the magnitude of the measured received power is within the first numerical range, the first device reports the first detection result; the first detection result is used to indicate that the first type of signal path is measured in a predetermined direction.
[0351] Exemplarily, the first parameter is the received power, the first numerical range is 6 < P < 10, where P is the received power; if the measured received power is 15, the first detection result is used to indicate that the first type of signal path is not measured in a predetermined direction; if the measured received power is 7, the first detection result is used to indicate that the first type of signal path is measured in a predetermined direction.
[0352] In some embodiments, the second information associated with the second path group includes a second range corresponding to an expected second parameter; based on the second numerical range and the magnitude of the second parameter measured in a predetermined direction, the first device reports the second detection result; wherein, the second detection result is used to indicate the measurement result of the second type of signal path measured in a predetermined direction.
[0353] In some embodiments, the second parameter is at least one of time delay, Doppler frequency, angle, and / or received power.
[0354] Taking the received power as an example for illustration below, but not limited to the received power, it can also be the time delay, Doppler frequency, angle, etc.
[0355] In some embodiments, when it is determined that the magnitude of the measured received power is outside the second numerical range, the first device reports the second detection result; the second detection result is used to indicate that the second type of signal path is measured in a predetermined direction.
[0356] In some embodiments, when it is determined that the magnitude of the measured received power is within the second numerical range, the first device reports the second detection result; the second detection result is used to indicate that the second type of signal path is not measured in a predetermined direction.
[0357] Exemplarily, the second parameter is the received power, the second numerical range is 3 < P < 9, where P is the received power; if the measured received power is 2, the first detection result is used to indicate that the second type of signal path is measured in a predetermined direction; if the measured received power is 8, the first detection result is used to indicate that the second type of signal path is not measured in a predetermined direction.
[0358] In some embodiments, the second information associated with the second path group includes a first change amount corresponding to an expected change in the second parameter; based on the magnitude of the first change amount and the change amount of the second parameter measured in a predetermined direction, the first device performs reporting of a third detection result; wherein, the third detection result is used to indicate the measurement result of measuring the second type of signal path in a predetermined direction.
[0359] The following takes the received power as an example for illustration, but is not limited to the received power, and may also be time delay, Doppler frequency, angle, etc.
[0360] In some embodiments, when it is determined that the change amount of the measured received power is outside the first change amount range, the first device performs reporting of a third detection result; the third detection result is used to indicate that the second type of signal path is measured in a predetermined direction.
[0361] In some embodiments, when it is determined that the change amount of the measured received power is within the first change amount range, the first device performs reporting of a third detection result; the third detection result is used to indicate that the second type of signal path is not measured in a predetermined direction.
[0362] Exemplarily, the second parameter is the received power, the first change amount range is 1 < P < 4, where P is the received power; if the measured change amount is 5, the first detection result is used to indicate that the second type of signal path is measured in a predetermined direction; if the measured received power is 3, the first detection result is used to indicate that the second type of signal path is not measured in a predetermined direction.
[0363] In some embodiments, the change amount of the received power may be the difference between the value of the received power measured at the first moment and the value of the power measured at the second moment. Exemplarily, the change amount of the received power may be the difference between the value of the received power measured at the 0th second and the received power measured at the 1st second. It can be understood that in some scenarios, the change amount can also be understood as the change rate, that is, the change amount of the received power per unit time, which is not limited herein.
[0364] In some embodiments, the change in received power can also be the difference between the received power value measured at the third time and the reference received power value set at the third time. For example, if the received power value measured at the first second is 'a' and the corresponding reference received power value set at the first second is 'b', then the change in received power can be 'x', where x = ab.
[0365] In some embodiments, a reference channel is determined based on a timestamp; based on the information obtained by jointly detecting the second type of signal path using the reference channel and the current signal, the first device determines the first change amount.
[0366] In some embodiments, a reference channel is determined based on a timestamp; the first device determines the first change amount based on a comparison between information of the second type of signal path associated with the reference channel and information obtained by measuring the second type of signal path in the detection channel.
[0367] In some embodiments, the first device determines the first change based on a comparison between locally stored reference information and information measured on the second type of signal path.
[0368] In some embodiments, at least one of the following is configured for the first path group and / or the second path group:
[0369] The first cycle is used to perform sensing measurements on the signal path;
[0370] The second cycle is used to report the detection results obtained on the signal path;
[0371] Triggering conditions, which are used to report the detection results obtained on the signal path.
[0372] In some embodiments, the triggering condition may be a condition distinct from the condition based on the detection results reported in the second cycle. For example, the triggering condition may be at least one of the following:
[0373] The number of detection results obtained is greater than the quantity threshold, for example, the quantity threshold is 5 times;
[0374] The obtained detection result is an abnormal detection result. For example, the detected received power is abnormal (e.g., greater than a certain power threshold or less than a certain power threshold).
[0375] The test results are within the preset numerical range, for example, a < received power. <b。
[0376] Once the above triggering conditions are met, the test results can be reported; otherwise, the test results do not need to be reported.
[0377] In some embodiments, the first period, the second period, and / or the triggering conditions of the first path group and the second path group are the same.
[0378] In some embodiments, the first period, the second period, and / or the triggering conditions of the first path group are configured with different information.
[0379] In some embodiments, the first period, the second period, and / or the triggering conditions of the second path group are configured with different information.

Subgroup 1 contains first-type signal paths L1 and L2, subgroup 2 contains first-type signal paths L3 and L4, and subgroup 3 contains first-type signals L5 and L6. The second path group B comprises three subgroups: subgroup 4, subgroup 5, and subgroup 6. Subgroup 4 contains second-type signal paths K1 and K2, subgroup 2 contains second-type signal paths K3 and K4, and subgroup 3 contains second-type signals K5 and K6.

[0516] In some embodiments, the above methods may include the methods of the communication system side, the first device, the second device, etc., as described above, which will not be repeated here.
[0517] To better understand the embodiments of this disclosure, the following exemplary embodiments are provided for further explanation:
[0518] In some embodiments, sensing operations on a sensing target are provided for STX (for a transmitter applied to sensing) and SRX (for a receiver applied to sensing), and the measurement and reporting are applicable to situations where multiple pairs of STX and SRX work together.
[0519] In some embodiments, for an STX or SRX, the sensing resources used to transmit sensing signals can be configured or dynamically indicated via higher-layer signaling.
[0520] In some embodiments, the configuration parameters of each sensing resource (corresponding to the first information in this disclosure) may include: time resources, frequency resources, beams, etc.
[0521] In some embodiments, the sensing resources of STX and SRX are the same in time and frequency, but the beam information is generally different.
[0522] In some embodiments, the configuration parameters of STX may also include the transmission power on the sensed resources.
[0523] In some embodiments, when STX or SRX is a base station, the aforementioned sensing resources need to be configured to each base station, for example, through the interface between gNBs or the interface between the core network and the base station.
[0524] In some embodiments, the aforementioned time resources are generally allocated according to a certain period P, thereby supporting continuous detection of the perceived target, thereby improving the perception accuracy and tracking the movement of the perceived target.
[0525] In some embodiments, for a sensing resource, a sensing signal can be transmitted over a time period of length D, starting from offset O, where D ≤ P. The time period D can be divided into one or more time units (TUs). Each TU repeatedly uses the same pattern to allocate Orthogonal Frequency Division Multiplexing (OFDM) symbols for transmitting the sensing signal.
[0526] In some embodiments, depending on the specific network configuration, the node responsible for allocating sensing resources (corresponding to the second device in this disclosure) may be a base station, UE, network device, related functional node, and / or SF, etc. For example, the node responsible for allocating sensing resources will be referred to as a processing node below.
[0527] In some embodiments, for a pair of STX and SRX, it is assumed that the processing node has already obtained information on each path of the sensed target detectable on the SRX side through sensing operations, including time delay, Doppler frequency, angle, and received power. These paths include paths that pass directly through the sensed target (corresponding to the first type of signal path in this disclosure) and paths that are affected by the target and pass through environmental objects (corresponding to the second type of signal path in this disclosure). When it is necessary to continuously track the sensed target, the processing node can simplify the sensing operations of the STX or SRX based on the information of these already obtained paths. Generally speaking, for a pair of STX and SRX, the possible target location information and the interaction between the target and environmental objects can be obtained by other methods, so that the processing node can simplify the sensing operations of the STX or SRX based on this known information.
[0528] In some embodiments, the processing node can configure the sensing resources (corresponding to the first sensing resources) and beams for transmitting sensing signals via STX.
[0529] In some embodiments, the beam may be directed toward the sensing target, thereby increasing the effective transmission power passing through the target, improving sensing performance, and reducing interference with communication or sensing operations in other directions.
[0530] In some embodiments, when considering the environmental object-assisted sensing operation, the processing node can also be configured to transmit a sensing resource (corresponding to a second sensing resource) and beam towards the environmental object via STX. After reflection from the environmental object, at least a portion of this beam at SRX is affected by the sensing target. Here, the environmental object and the sensing target may be located in the same direction, so that a configured sensing resource and beam can simultaneously cover both the sensing target and the environmental object.
[0531] In some embodiments, the sensing resources may be periodically configured or dynamically indicated.
[0532] In some embodiments, a sensing resource may be associated with only one sensing target, or it may be associated with multiple sensing targets.
[0533] In some embodiments, STX may not know the correspondence between sensing resources and sensing targets.
[0534] In some embodiments, referring to Figure 6a, it is assumed that the sensing target T is located between STX and an environmental object E1, i.e., the target T blocks or weakens the wireless signal transmitted from STX to E1, causing E1 to be invisible or have a weaker signal at SRX. In this relative position of the target T and the environmental object E1, both the path T-SRX directly reaching the receiver via the target T and the path E1-SRX that disappears or weakens carry the location information of the target T. The processing node can configure one or more sensing resources and beam information for STX. Each beam can point in the direction of the target T, which is also the direction of the environmental object E1. The sensing signal transmitted by STX using this beam can support two cases: on the one hand, the sensing signal reaches SRX after being reflected by the target T, i.e., path STX-T-SRX; on the other hand, due to the obstruction of the target T, the strength of the originally existing path STX-E1-SRX is weakened or disappears. The transmission power of the sensing resources can also be further configured.
[0535] In some embodiments, referring to Figure 6b, it is assumed that the sensing target T is located between an environmental object E2 and SRX, i.e., the target T blocks or weakens the wireless signal reflected from E2 to SRX, causing E2 to be invisible or have a weaker signal at SRX. In this relative position situation between the target T and the environmental object, both the path T-SRX that directly reaches the receiver via the target T and the path E2-SRX that disappears or weakens carry the location information of the target T.
[0536] In some embodiments, to utilize path-assisted sensing operations that are affected by a target and pass through environmental objects, the processing node can be configured with two types of sensing resources, STX and beam information. The first type of sensing resource (corresponding to the first sensing resource) and beam can point in the direction of the target T, and after reflection from the target T, reach SRX, i.e., path STX-T-SRX. The second type of sensing resource (corresponding to the second sensing resource) and beam can point in the direction of environmental objects; however, due to the obstruction of the target T, the intensity of the original path STX-E2-SRX is weakened or disappears. Alternatively, assuming a beam can cover E2 and the target T, a single sensing resource and beam can be configured to simultaneously cover E2 and the target T.
[0537] In some embodiments, the allocation cycles of the two types of sensing resources may be the same or different.
[0538] In some embodiments, the two types of sensing resources may be jointly dynamically indicated or dynamically indicated separately.
[0539] In some embodiments, for each of the above-mentioned sensing resources, if multiple sensing resources are included, the period can be configured separately for each sensing resource, or dynamically indicated separately.
[0540] In some embodiments, the processing node can configure the sensing resources to be detected by SRX and the corresponding beam information. When considering environmental object-assisted sensing operations, the processing node can configure SRX to detect different sensing resources and beams separately. The different sensing resources and beams are directed towards the sensing target and the environmental object, respectively. Here, the environmental object and the sensing target may be located in the same direction, so that a configured sensing resource and beam can simultaneously cover the sensing target and the environmental object. The sensing resources can be periodically configured or dynamically indicated.
[0541] In some embodiments, referring again to Figure 6a, to utilize path-assisted sensing operations influenced by target T and passing through environmental object E1, the processing node can configure multiple sensing resources and beam information for the SRX. A portion of the sensing resources (the third sensing resource) and beam can be pointed in the direction of target T, and the signal reflected by the target directly reaches the SRX, i.e., path STX-T-SRX. Another portion of the sensing resources (the fourth sensing resource) and beam can be pointed in the direction of environmental object E1; however, due to the obstruction of target T, the intensity of the original path STX-E1-SRX is weakened or disappears. Alternatively, assuming one beam can cover both E1 and target T, one sensing resource and beam can simultaneously cover both E1 and target T.
[0542] In some embodiments, as shown in Figure 6b, each beam can be pointed in the direction of the target T, which is also the direction of the environmental object E2. That is, a single sensing resource and beam simultaneously covers E2 and the target T. Using this beam to detect the sensing signal in the SRX can support two uses: firstly, detecting the sensing signal that reaches the SRX after being reflected from the target, i.e., the path STX-T-SRX; secondly, due to the obstruction of the target, the intensity of the original path STX-E2-SRX is weakened or disappears.
[0543] In some embodiments, for a single SRX, for each sensing resource, auxiliary information for the path to be sensed can be configured or dynamically indicated via higher-layer signaling, including expected latency, Doppler frequency, and / or angle. The angle information can be configured in the form of beams. The processing node can further configure the received power information related to each path.
[0544] In some embodiments, the SRX can perform sensing operations using information based on the aforementioned time delay, Doppler frequency, and / or angle.
[0545] In some embodiments, when considering the environmental object-assisted sensing operation, the paths to be sensed can be divided into two groups. The first group of paths (corresponding to the first path group) includes paths that directly pass through the sensing target. The second group of paths (corresponding to the second path group) includes paths that are affected by the target and pass through environmental objects.
[0546] In some embodiments, the parameter sets of the auxiliary information for the two sets of paths may be the same or different.
[0547] In some embodiments, the SRX may process the two sets of diameters using different methods.
[0548] In some embodiments, each set of paths may be associated with only one sensing target, or it may be associated with multiple sensing targets.
[0549] In some embodiments, the SRX may not know the correspondence between the multiple paths being sensed and the sensed target.
[0550] In some embodiments, paths directly passing through the target carry target information. Generally, the stronger the received power of such paths, the better for the sensing operation. When considering environmental objects assisting the sensing operation, paths influenced by the target and passing through environmental objects also carry target information. Generally, the greater the variation in the received power of such paths, the better for the sensing operation. In this method, the actual received power of the paths passing through environmental objects may be very small, or even indistinguishable from background noise.
[0551] In some embodiments, for the first set of paths, information on one or more paths that directly pass through the sensed target, detected by the SRX, is configured via higher-layer signaling or dynamically indicated, including the expected value or expected range of time delay, Doppler frequency, and angle.
[0552] In some embodiments, for the first set of paths, a desired received power P1 or a received power range R1 can also be configured. The processing node can configure the minimum desired received power for the paths requiring SRX detection of sensing signals using higher-layer signaling. The minimum desired received power can also be predefined or determined based on other parameters.
[0553] In some embodiments, for a first set of paths, if the measured received power of a path is not within the expected received power range (corresponding to a first numerical range), the SRX can report special power indication information. For example, if the measured received power of a path is less than the expected minimum received power, the SRX can report that the path was not detected. Exemplarily, the SRX can report only one bit of information, namely whether the measured received power of the path is not less than the expected minimum received power.
[0554] In some embodiments, for the first set of paths, if the measured path's time delay, Doppler frequency, or angle parameters are not within the expected range, the SRX can report special indication information. For example, the SRX can report that the path was not detected. Specifically, the SRX can report only one bit of information, namely, whether there is a path whose measured values of time delay, Doppler frequency, and angle are within the expected range.
[0555] In some embodiments, information about one or more paths detected by the SRX that are affected by the target and pass through environmental objects is configured or dynamically indicated by higher-level signaling, including the expected value or expected range of time delay, Doppler frequency, and angle.
[0556] In some embodiments, for the second set of paths, if only the interaction between fixed environmental objects and the sensing target is considered, the Doppler of the path can be 0 or very small, thus making it possible to omit the Doppler frequency information of the second set of paths in the configuration parameters.
[0557] In some embodiments, the expected received power P2 or the received power range R2 can be configured for the second path.
[0558] In some embodiments, the received power range R2 may be the same as or different from the received power range R1.
[0559] In some embodiments, the processing node can use higher-layer signaling to configure the maximum expected received power of the path for which the SRX-detected sensing signal needs to be sent.
[0560] In some embodiments, the maximum expected received power may also be predefined or determined based on other parameters.
[0561] In some embodiments, if the received power of a measured path is not within the expected received power range (second numerical range), the SRX can report special power indication information. For example, if the received power of a measured path is greater than the expected maximum received power, the SRX can report that the path has reappeared. Note: For a reappearing path, its propagation path is no longer blocked by the sensing target, so it is no longer suitable for assisting in the sensing of the sensing target.
[0562] For example, the SRX may report only one bit of information, namely whether the measured received power of the path is not greater than the expected maximum received power.
[0563] In some embodiments, for the second path, the expected received power change P3 or the range of received power change R3 can be configured.
[0564] In some embodiments, the processing node can be configured using higher-layer signaling to specify a minimum expected received power variation along the path for which the SRX-detected sensing signal needs to be received. This minimum expected received power variation can also be predefined or determined based on other parameters.
[0565] In some embodiments, if the measured change in received power of a path is not within the expected range of received power change (a first range of change), the SRX may report special power indication information. For example, if the measured change in received power of a path is less than the expected minimum change in received power, the SRX may report that the path has reappeared.
[0566] In some embodiments, for a re-emerging path, its propagation path is no longer obstructed by the sensing target, and therefore it is no longer applicable to assisting in the sensing of the sensing target. In particular, the SRX may report only one bit of information, namely whether the measured change in received power of the path is not less than the expected minimum change in received power.
[0567] In some embodiments, for the second set of paths, if the measured path's time delay, Doppler frequency, or angle parameters are not within the expected range, the SRX can report special indication information. For example, the SRX can report that the path was not detected. Specifically, the SRX can report only one bit of information, namely, whether there is a path whose measured time delay, Doppler frequency, and angle are within the expected range.
[0568] In some embodiments, the processing node can be configured to use the SRX as a timestamp for the background channel for comparison.
[0569] In some embodiments, the SRX can obtain locally stored background channel information based on a timestamp and process it in conjunction with the current channel to detect the second set of paths. Alternatively, the processing node can directly configure the SRX to use reference delay, Doppler frequency, angle, and received power information for each path in the second set of paths as a comparison. Thus, the SRX obtains the change in received power for a path by comparing its received power in the current channel with the reference received power.
[0570] In some embodiments, the two sets of paths can be configured with the same sensing measurement and reporting cycle, or with the same event-triggered sensing result reporting conditions. Alternatively, the sensing measurement and reporting cycle, or the event-triggered sensing result reporting conditions, can be configured separately for each of the two sets of paths. Each set of paths can be further divided into multiple subgroups, thereby configuring the sensing measurement and reporting cycle, or the event-triggered sensing result reporting conditions, separately for each subgroup.
[0571] Example 1:
[0572] A pair of sensing transmitters (STX) and sensing receivers (SRX) are employed. When sensing a target (hereinafter referred to as the target), the STX transmits a sensing signal, such as a reference signal for sensing operations, and the SRX receives the sensing signal. The SRX can detect multipath components in the received sensing signal. Different multipath components differ from other multipath components in at least one of the following aspects: time delay, angle, and Doppler frequency. In addition, the intensity of each multipath, i.e., the received power, is also an important parameter. The above multipath parameters, i.e., time delay, angle, Doppler frequency, and intensity, reflect the characteristics of the sensing target in the area. Furthermore, to improve the accuracy of sensing, multiple STXs and / or SRXs can be configured to sense the same target. The measurement results of the SRXs are jointly processed by the Sensing Function (SF) to obtain the target's location and characteristic information. The SF can be located in the core network or in the Radio Access Network (RAN). In particular, the SF can be one of the STXs or SRXs that perform the sensing operations described above.
[0573] The presence and movement of a sensed target will interact with the propagation of wireless signals from environmental objects. Please refer again to Figure 1c, which is a schematic diagram of the interaction between the sensed target and the environment. In Figure 1c, E, E1, E2, E3, and E4 represent environmental objects, and T1, T2, T3, and T4 represent the sensed target. The following describes the interaction between the sensed target and environmental objects.
[0574] As shown in Figure 1c, the interaction between the perceived target and environmental objects can include one or more of the following situations:
[0575] 1. The presence and movement of a sensed target may block or weaken the wireless signal transmitted from an STX to an environmental object, causing the environmental object to become invisible or have a weaker signal at the SRX. For example, in Figure 1, the wireless signal from the STX to the environmental object E1 is blocked by the sensed target T1.
[0576] 2. The presence and movement of the sensing target may block or weaken the wireless signal reflected from an environmental object to the SRX, causing the environmental object to become invisible or have a weaker signal at the SRX. For example, the wireless signal from the environmental object E2 to the SRX in Figure 1 is blocked by the sensing target T1.
[0577] 3. Due to the presence and movement of the target, an environmental object may block or weaken the wireless signal from STX to the target, causing the target to become invisible or the signal to weaken at SRX. For example, in Figure 1, the wireless signal from STX to the target T2 is blocked by the environmental object E3.
[0578] 4. Due to the presence and movement of the target, an environmental object may block or weaken the wireless signal reflected from the target to the SRX, causing the target to become invisible or its signal to weaken at the SRX. For example, the wireless signal reflected from the target T3 to the SRX in Figure 1 is blocked by the environmental object E4.
[0579] 5. The presence and movement of the detected target may block or weaken the wireless signal from STX to SRX, meaning that SRX may detect that STX is invisible or the signal is weak. For example, in Figure 1, the wireless signal from STX to SRX is blocked by the detected target T4.
[0580] 6. Due to the presence and movement of the sensed target, some wireless signals reflected by the sensed target may reach an environmental object, causing the wireless signal reflected from this environmental object to the SRX to become stronger. Because the path from the STX to the sensed target to the environmental object is not a straight path (LOS), i.e., its delay is greater than that of the straight path from the STX to the environmental object, the SRX may be able to distinguish the increased wireless signal, i.e., the new path reflected to the SRX, from the delay characteristics.
[0581] 7. The wireless signal of the environmental object E at SRX is not affected by the perceived target.
[0582] 8. The wireless signal of the sensing target T1 at the SRX is not affected by environmental objects.
[0583] When multiple STXs or multiple SRXs are present in the area, the impact of the presence and movement of the sensed target generally differs for different pairs of STXs and SRXs. The aforementioned impacts on environmental objects and / or the received signals of the STXs at the SRXs due to the presence and movement of the sensed target can be used to assist in the sensing operation of the sensed target. Not generally, this invention describes the sensing operation of a pair of STXs and SRXs on a sensed target, and the measurements and reports are applicable to situations where multiple pairs of STXs and SRXs work together.
[0584] For an STX or SRX, the sensing resources used to transmit sensing signals can be configured via higher-layer signaling or dynamically indicated. The configuration of each sensing resource can include parameters such as time resources, frequency resources, and beamforming. The sensing resources of the STX and SRX are identical in time and frequency, but their beamforming information is generally different. The configuration parameters of the STX can also include the transmission power on the sensing resource. When the STX / SRX is a base station, the aforementioned sensing resources need to be configured for each base station, for example, through the interface between gNBs or the interface between the core network and the base station. The aforementioned time resources are generally allocated according to a certain period P, thereby supporting continuous detection of the sensing target, improving sensing accuracy, and tracking the movement of the sensing target. For a single sensing resource, sensing signals can be transmitted from offset 0 for a time period of length D, where D ≤ P. The time period D can be equally divided into one or more time units TU. Each TU repeatedly uses the same pattern to allocate OFDM symbols for transmitting sensing signals. Depending on the specific network configuration, the node responsible for allocating sensing resources can be a base station, UE, network equipment, related functional nodes, SF, etc. Not generally, the node responsible for sensing resource allocation will be referred to as the processing node.
[0585] For a pair of STX / SRX, assume the processing node has already obtained information on all paths of the detectable target on the SRX side through sensing operations, including time delay, Doppler frequency, angle, and received power. These paths include paths directly passing the target and paths affected by the target and passing through environmental objects. When continuous tracking of the target is required, the processing node can simplify the STX / SRX sensing operations based on this already obtained path information. Generally speaking, for a pair of STX / SRX, possible target location information and the interaction between the target and environmental objects can be obtained through other methods, thus the processing node can simplify the STX / SRX sensing operations based on this known information.
[0586] For the STX configuration, please refer to Figure 6a:
[0587] The processing node can configure sensing resources and beams for STX transmission of sensing signals. The beam can be oriented towards the sensing target, thereby increasing the effective transmission power through the target, improving sensing performance, and reducing interference with communication or sensing operations in other directions. When considering environmental object-assisted sensing operations, the processing node can also configure STX transmission to be oriented towards the environmental object, where at least a portion of the beam reflected by the environmental object is affected by the sensing target at the SRX. Here, the environmental object and the sensing target may be located in the same direction, so a configured sensing resource and beam can simultaneously cover both the sensing target and the environmental object. The sensing resources can be periodically configured or dynamically indicated. A sensing resource can be associated with only one sensing target, or it can be associated with multiple sensing targets. The STX may not be aware of the correspondence between sensing resources and sensing targets.
[0588] As shown in Figure 6a, assuming the sensing target T is located between STX and an environmental object E1, meaning target T blocks or weakens the wireless signal transmitted from STX to E1, causing E1 to be invisible or have a weaker signal at SRX. Under this relative position of target T and environmental object E1, both the path T-SRX directly reaching the receiver via target T and the path E1-SRX that disappears or weakens carry the location information of target T. The processing node can configure one or more sensing resources and beam information for STX. Each beam can point in the direction of target T, which is also the direction of environmental object E1. The sensing signal transmitted by STX using this beam can support two scenarios: on the one hand, the sensing signal reaches SRX after being reflected by target T, i.e., path STX-T-SRX; on the other hand, due to the obstruction of target T, the strength of the originally existing path STX-E1-SRX is weakened or disappears. The transmission power of the sensing resources can also be further configured.
[0589] As shown in Figure 6b, suppose the target T is located between an environmental object E2 and SRX, meaning the target T blocks or weakens the wireless signal reflected from E2 to SRX, causing E2 to be invisible or have a weaker signal at SRX. In this relative positional situation of the target T and the environmental object, both the path T-SRX directly reaching the receiver via the target T and the path E2-SRX that disappears or weakens carry the target T's position information. To utilize the path affected by the target and passing through the environmental object to assist in sensing operations, the processing node can configure two types of sensing resources (STX and SRX) and beam information. The first type of sensing resource and beam can be pointed in the direction of the target T, reaching SRX after reflection from the target T, i.e., path STX-T-SRX. The second type of sensing resource and beam can be pointed in the direction of the environmental object; however, due to the obstruction of the target T, the intensity of the originally existing path STX-E2-SRX is weakened or disappears. Alternatively, one beam can cover both E2 and the target T, or one sensing resource and beam can simultaneously cover both E2 and the target T. The allocation periods for the two types of sensing resources can be the same or different. The two types of sensing resources can be jointly and dynamically indicated, or dynamically indicated separately. For each type of sensing resource, if it includes multiple sensing resources, the period can be configured separately for each sensing resource, or they can be dynamically indicated separately.
[0590] For SRX configurations:
[0591] The processing node can be configured with the sensing resources to be detected by SRX and the corresponding beam information. When considering environmental object-assisted sensing operations, the processing node can be configured to detect different sensing resources and beams using SRX. These different sensing resources and beams are directed towards the sensing target and the environmental object, respectively. Here, the environmental object and the sensing target may be located in the same direction, so a single configured sensing resource and beam can simultaneously cover both the sensing target and the environmental object. The sensing resources can be periodically configured or dynamically indicated.
[0592] In Figure 6a, to utilize path-assisted sensing operations influenced by target T and passing through environmental object E1, the processing node can configure multiple sensing resources and beam information for the SRX. A portion of the sensing resources and beam can be pointed in the direction of target T, with the signal reflected by the target directly reaching the SRX, i.e., path STX-T-SRX. Another portion of the sensing resources and beam can be pointed in the direction of environmental object E1; however, due to the obstruction of target T, the intensity of the original path STX-E1-SRX is weakened or disappears. Alternatively, assuming one beam can cover both E1 and target T, a single sensing resource and beam can simultaneously cover both E1 and target T.
[0593] In Figure 6b, each beam can be pointed in the direction of the target T, which is also the direction of the environmental object E2. That is, a single sensing resource and beam simultaneously cover E2 and the target T. Using this beam to detect the sensing signal in the SRX can support two uses: firstly, detecting the sensing signal that reaches the SRX after being reflected from the target, i.e., the path STX-T-SRX; secondly, due to the obstruction of the target, the intensity of the original path STX-E2-SRX is weakened or disappears.
[0594] For an SRX, for each sensed resource, auxiliary information for the paths to be sensed can be configured or dynamically indicated via higher-layer signaling, including expected delay, Doppler frequency, and / or angle. Angle information can be configured in the form of beams. The processing node can further configure the received power information for each path. Accordingly, the SRX can perform sensing operations using the aforementioned delay, Doppler frequency, and / or angle information. When considering environmental object-assisted sensing operations, the paths to be sensed can be divided into two groups. The first group includes paths that directly pass through the sensed target. The second group includes paths affected by the target and passing through environmental objects. The parameter sets of the auxiliary information for the two groups of paths can be the same or different. The SRX can process the two groups of paths using different methods. Each group of paths can be associated with only one sensed target, or it can be associated with multiple sensed targets. The SRX may not know the correspondence between the multiple sensed paths and the sensed targets.
[0595] In this operation, the path directly passing through the target carries the target's information. Generally, the stronger the received power of such a path, the better for the sensing operation. When considering the sensing operation assisted by environmental objects, paths influenced by the target and passing through environmental objects also carry the target's information. Generally, the greater the change in the received power of such paths, the better for the sensing operation. In this method, the actual received power of the path passing through environmental objects may be very small, or even indistinguishable from background noise.
[0596] For the first set of paths, information on one or more paths directly passing the sensing target, detected by SRX, is configured or dynamically indicated via higher-layer signaling. This includes the expected values or expected ranges of time delay, Doppler frequency, and angle. The expected received power P1 or received power range R1 can also be configured for the first set of paths. The processing node can use higher-layer signaling to configure the minimum expected received power for the paths requiring SRX to detect the sensing signal. The minimum expected received power can also be predefined or determined based on other parameters.
[0597] For the first set of paths, if the measured received power of the path is not within the expected received power range, the SRX can report special power indication information. For example, if the measured received power of the path is less than the expected minimum received power, the SRX can report that the path was not detected. In particular, the SRX can report only one bit of information, namely whether the measured received power of the path is not less than the expected minimum received power.
[0598] For the first set of paths, if the measured path's time delay, Doppler frequency, or angle parameters are outside the expected range, the SRX can report specific indication information. For example, the SRX can report that the path was not detected. Specifically, the SRX can report only one bit of information: whether a path exists whose measured time delay, Doppler frequency, and angle are within the expected range.
[0599] For the second set of paths, information on one or more paths detected by the SRX that are affected by the target and pass through environmental objects is configured or dynamically indicated via higher-layer signaling, including the expected value or expected range of time delay, Doppler frequency, and angle. For the second set of paths, if only the interaction between fixed environmental objects and the sensed target is considered, the Doppler of the path can be 0 or very small, thus it is possible to omit the Doppler frequency information of the second set of paths in the configuration parameters. For the second set of paths, the expected received power P2 or the received power range R2 can be configured. The received power range R2 can be the same as or different from the received power range R1. The processing node can configure the maximum expected received power of the path for which the SRX needs to detect the sensed signal using higher-layer signaling. The maximum expected received power can also be predefined or determined based on other parameters. Using this method, if the received power of the measured path is not within the expected received power range, the SRX can report special power indication information. For example, if the received power of the measured path is greater than the expected maximum received power, the SRX can report that the path has reappeared. Note: For re-emerging paths, their propagation paths are no longer blocked by the sensing target, so they are no longer suitable for assisting in the sensing of the target. In particular, SRX can report only one bit of information, namely whether the received power of the measured path is not greater than the expected maximum received power.
[0600] For the second set of paths, the expected received power change P3 or the range R3 of the received power change can be configured. The processing node can use higher-layer signaling to configure the minimum expected received power change for the path requiring SRX detection of the sensing signal. The minimum expected received power change can also be predefined or determined based on other parameters. Using this method, if the measured received power change of a path is not within the expected range, the SRX can report special power indication information. For example, if the measured received power change of a path is less than the expected minimum received power change, the SRX can report that the path has reappeared. Note: For reappearing paths, their propagation path is no longer blocked by the sensing target, so they are no longer suitable for assisting in the sensing of the target. In particular, the SRX can report only one bit of information, namely whether the measured received power change of the path is not less than the expected minimum received power change.
[0601] For the second set of paths, if the measured path's time delay, Doppler frequency, or angle parameters are outside the expected range, the SRX can report specific indication information. For example, the SRX can report that the path was not detected. Specifically, the SRX can report only one bit of information: whether a path exists whose measured time delay, Doppler frequency, and angle are within the expected range.
[0602] For the second set of paths, the processing node can configure the SRX to use the timestamp of the background channel for comparison. The SRX can obtain the locally stored background channel information based on the timestamp and process it together with the current channel to detect the second set of paths. Alternatively, the processing node can directly configure the SRX to use the reference delay, Doppler frequency, angle, and received power information for each path in the second set of paths for comparison. Thus, the SRX obtains the amount of received power change for a path by comparing the received power of a path in the current channel with the reference received power.
[0603] The two sets of paths described above can be configured with the same sensing measurement and reporting cycle, or with the same event-triggered sensing result reporting conditions. Alternatively, the sensing measurement and reporting cycle, or the event-triggered sensing result reporting conditions, can be configured separately for each set of paths. Each set of paths can be further divided into multiple subgroups, allowing for separate configuration of the sensing measurement and reporting cycle, or separate configuration of the event-triggered sensing result reporting conditions for each subgroup.
