Communication-aware method, aware network element, aware transmitting device and aware receiving device

Abstract

The present disclosure relates to a communication sensing method, a sensing network element, a sensing sending device and a sensing receiving device. In at least one embodiment of the present disclosure, for an intrusion sensing scene, two sensing modes, i.e., an intrusion detection mode and an intrusion tracking mode, are configured, different sensing resources are configured based on different requirements of the two sensing modes. For the intrusion detection mode, the configured sensing resources only need to meet the detection of whether the intrusion target exists or not, and therefore fewer sensing resources can be configured. For the intrusion tracking mode, the configured sensing resources need to meet the tracking requirement of the intrusion target, and therefore more sensing resources can be configured to improve the tracking accuracy of the intrusion target. Compared with the prior art, in which the sensing receiving device needs to constantly report measurement information, the present disclosure optimizes the configuration of the sensing resources, the sensing receiving device only needs to send the measurement information on the optimized sensing resources, and does not need to constantly report the measurement information, which can reduce the air interface resource overhead.

[0002] Integrated Sensing and Communication (ISAC) introduces wireless sensing capabilities into wireless mobile communication. The principle of wireless sensing is to transmit wireless signals to the environment to be sensed, while simultaneously collecting the reflected, scattered, or multipath-transmitted wireless signals at the receiving end. Because the collected wireless signals are influenced by the environment, environmental information can be obtained by processing these signals, thus achieving environmental sensing.

[0003] In integrated communication and sensing technology, sensing network elements need to perform intrusion detection and discrimination based on measurement information reported by each receiver.

[0162] In at least one embodiment of this disclosure, for an intrusion perception scenario, two perception modes (intrusion detection mode and intrusion tracking mode) are configured, and different perception resources are configured based on the different requirements of the two perception modes. For example, for the intrusion detection mode, the perception requirement is to detect the existence of an intrusion target, and the configured perception resources only need to meet the detection of the presence or absence of the intrusion target, without the need to configure dense perception resources, thus requiring fewer perception resources. For the intrusion tracking mode, the perception requirement is to track a identified intrusion target, and the configured perception resources need to meet the tracking requirements of the intrusion target (e.g., ranging, velocity, and angle measurement), thus requiring more perception resources (compared to the perception resources in the intrusion detection mode) to improve the tracking (positioning) accuracy of the intrusion target. Compared to the prior art, where the sensing receiving device needs to continuously report measurement information, the embodiments of this disclosure optimize the configuration of perception resources. The sensing receiving device only needs to send measurement information on the optimized perception resources, without the need for continuous reporting of measurement information, which can reduce air interface resource overhead.

[0173] To better understand the above-described objectives, features, and advantages of this disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are only some, not all, of the embodiments of this disclosure. The specific embodiments described herein are merely for explaining this disclosure and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure are within the scope of protection of this disclosure.

[0174] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0175] Wireless sensing is generally divided into: single-base sensing and dual-base sensing.

[0176] Single-base sensing refers to a single node transmitting a sensing reference signal and receiving the echo. Single-base sensing includes single-base station sensing or single-terminal sensing. Single-base station sensing involves the base station transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object (e.g., an intrusion target), and the base station receiving the reflected and / or scattered sensing reference signal. Single-terminal sensing involves the terminal transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object, and the terminal receiving the reflected and / or scattered sensing reference signal.

[0177] Dual-base sensing refers to a scenario where one node transmits a sensing reference signal, and another node receives the same signal. Dual-base sensing includes dual-base station sensing, dual-terminal sensing, base station-terminal sensing, or terminal-base station sensing. Dual-base station sensing involves one base station transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object, and received by the other base station. Dual-terminal sensing involves one terminal transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object, and received by the other terminal. Base station-terminal sensing involves a base station transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object, and received by the terminal. Terminal-base station sensing involves a terminal transmitting a sensing reference signal, which is then reflected and / or scattered by the sensing object, and received by the base station.

[0178] In this context, the intrusion target is a device that is not communicating with the communication system and is to be detected, located, or tracked. Because the intrusion target is not communicating with the communication system, the sensing system is unaware of its presence. For example, the intrusion target is a device that enters the sensing system's detection range without authorization. The sensing receiving device estimates the intrusion target's position, velocity, and orientation by receiving the sensing reference signals reflected and / or scattered by the intrusion target; this is a form of passive localization.

[0179] At least one embodiment of this disclosure provides a communication sensing method, a sensing network element, a sensing transmitting device, and a sensing receiving device. In at least one embodiment of this disclosure, for an intrusion sensing scenario, two sensing modes (intrusion detection mode and intrusion tracking mode) are configured, and different sensing resources are configured based on the different requirements of the two sensing modes. For example, for the intrusion detection mode, the sensing requirement is to detect the existence of an intrusion target; the configured sensing resources only need to satisfy the detection of the intrusion target's presence, without the need for dense sensing resources, thus requiring fewer sensing resources. For the intrusion tracking mode, the sensing requirement is to track a identified intrusion target; the configured sensing resources need to meet the tracking requirements of the intrusion target (e.g., ranging, velocity, and angle measurement), thus requiring more sensing resources (compared to the sensing resources in the intrusion detection mode) to improve the tracking (positioning) accuracy of the intrusion target. Compared to the prior art, where the sensing receiving device needs to continuously report measurement information, the embodiments of this disclosure optimize the configuration of sensing resources. The sensing receiving device only needs to send measurement information on the optimized sensing resources, without the need for continuous reporting of measurement information, which can reduce air interface resource overhead.

[0180] Figure 1This is a flowchart illustrating a communication sensing method provided in an embodiment of this disclosure. The communication sensing method is applied to a sensing function (SF). A sensing function (SF) is a network element that provides sensing services; for example, a sensing function can be a sensing server, an existing network element providing sensing services, or an undefined network element providing sensing services. Figure 1 As shown, the method may include, but is not limited to, steps 101 and 102:

[0181] In step 101, configuration information is determined, which includes perception mode and / or perception resources; the perception mode includes intrusion detection mode and / or intrusion tracking mode; wherein the perception resources of the intrusion detection mode are less than those of the intrusion tracking mode.

[0182] The sensing resources include frequency domain resources and / or time domain resources. Frequency domain resources can be pre-allocated sensing frequency resources in units of resource elements (REs) or resource blocks (RBs). Time domain resources can be pre-allocated sensing time domain resources in units of orthogonal frequency division multiplexing (OFDM) symbol length or time slot length.

[0183] In this embodiment, two new perception modes are configured for intrusion perception scenarios: intrusion detection mode and intrusion tracking mode. These two perception modes have different perception requirements: the perception requirement of intrusion detection mode is to detect whether an intrusion target exists, while the perception requirement of intrusion tracking mode is to track a identified intrusion target.

[0184] In this embodiment, the sensing network element configures different sensing resources based on the different requirements of the two sensing modes. For example, for the intrusion detection mode, the sensing requirement is to detect the existence of an intrusion target. The configured sensing resources only need to meet the detection requirements and do not need to be configured with dense sensing resources, so fewer sensing resources can be configured. However, for the intrusion tracking mode, the sensing requirement is to track a identified intrusion target. The configured sensing resources need to meet the tracking requirements of the intrusion target (e.g., ranging, velocity, and angle measurement), so more sensing resources can be configured (compared to the sensing resources in the intrusion detection mode) to improve the tracking (localization) accuracy of the intrusion target.

[0185] In step 102, configuration information is sent.

[0186] In this embodiment, the sensing network element can determine the sensing transmitting device and sensing receiving device participating in the sensing based on the sensing area and the sensing capabilities reported by at least one communication device. The sensing network element sends configuration information to the sensing transmitting device and sensing receiving device, so that the sensing transmitting device sends a sensing reference signal based on the configuration information, and the sensing receiving device receives the sensing reference signal based on the configuration information.

[0187] In a collaborative sensing scenario, a sensing reference signal is sent by a sensing transmitting device and received by at least one sensing receiving device. Therefore, the sensing network element determines a sensing transmitting device and at least one sensing receiving device, and sends configuration information to the sensing transmitting device and each sensing receiving device.

[0188] In this context, the sensing transmitting device is the node that transmits the sensing reference signal, and can be a base station (BS) or a terminal (e.g., user equipment (UE) or user terminal (UT)). The sensing receiving device is the node that receives the sensing reference signal, and can be a base station (BS) or a terminal (e.g., user equipment (UE) or user terminal (UT)).

[0189] As can be seen, compared with the prior art, where the sensing receiving device needs to continuously report measurement information, the embodiments of this disclosure optimize the configuration of sensing resources. The sensing receiving device only needs to send measurement information on the optimized sensing resources, without having to continuously report measurement information, which can reduce air interface resource overhead.

[0190] In some embodiments, the configuration information determined in step 101 includes: sensing mode, sensing resources (i.e., time-frequency resources of the sensing reference signal), and at least one of the following (1) to (4):

[0191] (1) The transmission period of the sensing reference signal.

[0192] The transmission period of the sensing reference signal in intrusion detection mode can differ from that in intrusion tracking mode. For example, the transmission period of the sensing reference signal in intrusion detection mode may be longer than that in intrusion tracking mode.

[0193] (2) Perceive the form of the reference signal.

[0194] For example, the sensing reference signal may be in the form of a reference signal already defined by a standard, and / or a reference signal used for communication-sensing integration that is not yet defined by a standard. The reference signal already defined by a standard includes at least one of the following:

[0195] It can be used for 5G positioning, such as Positioning Reference Signal (PRS), Channel State Information-Reference Signal (CSI-RS), and Sounding Reference Signal for Positioning (SRS-Pos).

[0196] (3) The amount of data reported by the sensing and receiving devices.

[0197] In this embodiment, if the sensing mode includes an intrusion tracking mode, the reported quantity includes intrusion measurement quantity. The intrusion measurement quantity includes at least one of the following: sensing information from the sensing receiving device, number of intrusion targets, type of intrusion target, reliability of the number of intrusion targets, and reliability of the type of intrusion target.

[0198] The sensing information of the sensing receiving device includes at least one of the following:

[0199] Raw sensory information, preliminary sensory information, and measurement information.

[0200] The raw sensing information includes, for example, the Channel Impulse Response (CIR). Preliminary sensing information includes, for example, at least one of the Time of Arrival (TOA) spectrum and the Doppler map. Measurement information includes, for example, at least one of the Time of Arrival, Angle of Arrival (AOA), velocity, and Doppler measurements.

[0201] In this embodiment, if the sensing mode includes an intrusion detection mode, the reported quantity includes intrusion information. The intrusion information includes at least one of the following a to f:

[0202] a. Intrusion judgment information.

[0203] For example, an intrusion decision information of zero indicates no intrusion, while an intrusion decision information of 1 indicates an intrusion has occurred.

[0204] b. Number of targets to be invaded.

[0205] For example, the number of intrusion targets is a positive integer greater than zero, and the resolution is 1.

[0206] c. Type of intrusion target.

[0207] The intrusion target type is used to help determine whether the intrusion target needs to be tracked. For example, an intrusion target type of zero represents a pedestrian, an intrusion target type of 1 represents a car, and an intrusion target type of 2 represents an airplane.

[0208] d. Reliability of intrusion judgment.

[0209] For example, intrusion decision reliability is a value between (0,1) with a resolution of 1 / 2^N, where N is a positive integer. Intrusion decision reliability reflects the degree of trust that the sensing receiving device has in intrusion decision information.

[0210] e. Reliability of the number of intrusion targets.

[0211] For example, the reliability of the number of intrusion targets is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of the number of intrusion targets reflects the degree of trust that the sensing receiving device has in the number of intrusion targets.

[0212] f. Reliability of the type of intrusion target.

[0213] For example, the reliability of an intrusion target type is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of an intrusion target type reflects the degree of trust that the sensing receiving device has in the type of intrusion target.

[0214] The reporting format of the reported quantity can be [sensing and receiving device identifier, intrusion judgment information, intrusion judgment reliability], or [sensing and receiving device identifier, number of intrusion targets, reliability of the number of intrusion targets, type of intrusion targets, reliability of the type of intrusion targets], or [sensing and receiving device identifier, intrusion judgment information, reliability of intrusion judgment, number of intrusion targets, reliability of the number of intrusion targets, type of intrusion targets, reliability of the type of intrusion targets].

[0215] In some embodiments, intrusion decision information is a mandatory reporting item, while its corresponding reliability is an optional reporting item. The remaining information and their corresponding reliability are optional reporting items.

[0216] (4) Reporting conditions of sensing and receiving devices.

[0217] In this embodiment, if the sensing mode includes an intrusion detection mode, the reporting conditions of the sensing receiving device include any one of the following A to C:

[0218] A. The sensing receiving device receives the sensing reference signal each time.

[0219] In A, the sensing network element is pre-configured with a historical information collection period to enable the sensing receiving device to collect historical information. During the historical information collection period, the sensing receiving device does not send any reports. After the historical information collection period ends, the period at which the sensing receiving device sends reports is the same as the period at which the sensing reference signal is sent.

[0220] B. The sensing and receiving device receives the sensing reference signal multiple times.

[0221] In B, the period during which the sensing and receiving device transmits the reported data is proportional to the period during which the sensing reference signal is transmitted. For example, H:1 means that the sensing and receiving device transmits intrusion information once after receiving H sensing reference signals. The sensing and receiving device can store historical information for the transmission periods of H sensing reference signals.

[0222] C. When the sensing and receiving device determines that an intrusion has occurred.

[0223] In C, the sensing and receiving device only sends intrusion information when an intrusion is detected, and does not send intrusion information at other times.

[0224] In this embodiment, if the sensing mode includes an intrusion tracking mode, the period during which the sensing receiving device sends the reported data is the same as the period during which the sensing reference signal is sent.

[0225] In some embodiments, after sending configuration information in step 102, the sensing network element can also receive the reported data sent by the sensing receiving device and process the reported data based on the sensing mode.

[0226] In this embodiment, if the perception mode includes an intrusion detection mode, the reported quantity includes intrusion information. The intrusion information includes at least one of the following: intrusion decision information, number of intrusion targets, type of intrusion target, reliability of intrusion decision, reliability of the number of intrusion targets, and reliability of the type of intrusion target.

[0227] In this embodiment, if the sensing mode includes an intrusion tracking mode, the reported quantity includes intrusion measurement quantity. The intrusion measurement quantity includes at least one of the following: sensing information from the sensing receiving device, number of intrusion targets, type of intrusion target, reliability of the number of intrusion targets, and reliability of the type of intrusion target.

[0228] In this embodiment, the sensing network element processes the reported data based on the sensing mode, including the following (1) or (2):

[0229] (1) If the perception mode includes the intrusion detection mode, then determine whether an intrusion has occurred based on the intrusion information.

[0230] (2) If the sensing mode includes the intrusion tracking mode, then the intrusion is determined to be over based on the intrusion measurement and the location information of the sensing receiving device.

[0231] In some embodiments, if the sensing mode includes an intrusion detection mode, the sensing network element determines whether an intrusion has occurred based on the intrusion information, including the following (1) to (3):

[0232] (1) Determine whether an intrusion has occurred based on at least one of the intrusion decision information reported by multiple sensing and receiving devices and the reliability of the intrusion decision.

[0233] In this embodiment, the sensing network element performs intrusion judgment again by summarizing the intrusion judgment information and / or intrusion judgment reliability reported by each sensing receiving device. It does not need to combine the sensing information of each sensing receiving device to make a judgment, so there is no need for the sensing receiving device to report sensing information, thus reducing air interface resource overhead.

[0234] For example, the sensing network element aggregates the intrusion judgment information reported by each sensing receiving device (let's assume it's p). i ) and intrusion decision reliability (assuming w) i Then, an intrusion decision is made again. Here, i represents the i-th sensing receiving device participating in collaborative sensing, and B is the number of sensing receiving devices participating in collaborative sensing. Two possible methods for making a second intrusion decision are as follows: A or B:

[0235] A. Weighted linear combination method:

[0236]

[0237] B. Weighted average method:

[0238]

[0239] It should be noted that if the sensing and receiving device does not report the reliability of the intrusion decision, then w in A and B... i The value is 1.

[0240] (2) Determine the number of intrusion targets based on at least one of the number of intrusion targets reported by multiple sensing and receiving devices and the reliability of the number of intrusion targets.

[0241] In this embodiment, the sensing network element can determine the number of intrusion targets by summarizing the number of intrusion targets and / or the reliability of the number of intrusion targets reported by each sensing receiving device.

[0242] For example, the sensing network element aggregates the number of intrusion targets and / or the reliability of the number of intrusion targets reported by each sensing receiving device, and determines the number of intrusion targets using a weighted linear combination method. If the result of the weighted linear combination method is not an integer, the number of intrusion targets is determined by rounding.

[0243] (3) Determine the intrusion target type based on at least one of the intrusion target type reported by multiple sensing and receiving devices and the reliability of the intrusion target type.

[0244] In this embodiment, the sensing network element determines the intrusion target type by summarizing the intrusion target types and / or intrusion target type reliability reported by each sensing receiving device and using a weighted linear combination method. If the result of the weighted linear combination method is not an integer, the intrusion target type is determined by rounding.

[0245] If there is only one sensing receiving device, the sensing network element determines whether an intrusion has occurred, the number of intrusion targets, and the type of intrusion targets based on at least one of the intrusion decision information, intrusion decision reliability, number of intrusion targets, reliability of the number of intrusion targets, type of intrusion targets, and reliability of the type of intrusion targets reported by the sensing receiving device.

[0246] In some embodiments, if the sensing mode includes an intrusion tracking mode, the sensing network element determines whether the intrusion has ended based on the intrusion measurement and the location information of the sensing receiving device, including the following (1) and (2):

[0247] (1) Based on the intrusion measurement data reported by multiple sensing and receiving devices and the location information of multiple sensing and receiving devices, determine the tracking information of the intrusion target.

[0248] The intrusion measurement parameters include at least one of the following: sensing information from the sensing receiving device, the number of intrusion targets, the type of intrusion target, the reliability of the number of intrusion targets, and the reliability of the type of intrusion target. The sensing information from the sensing receiving device includes at least one of the following:

[0249] Raw sensory information, preliminary sensory information, and measurement information.

[0250] The raw sensing information includes, for example, the channel impulse response (CIR). The preliminary sensing information includes, for example, at least one of the time of arrival (TOA) spectrum and the Doppler map. The measurement information includes, for example, at least one of the time of arrival, angle of arrival (AOA), velocity, and Doppler measurements.

[0251] The tracking information for the intrusion target includes its location, speed, and orientation.

[0252] (2) Determine whether the intrusion has ended based on at least one of the following: the tracking information of the intrusion target, the number of intrusion targets reported by multiple sensing and receiving devices, and the type of intrusion target.

[0253] In some embodiments, after the sensing network element determines whether an intrusion has occurred or whether the intrusion has ended, it further performs any one of the following (1) to (4):

[0254] (1) If the perception mode is intrusion detection mode and the current judgment is that there is an intrusion, then the perception mode in the configuration information will be changed to intrusion tracking mode.

[0255] (2) If the perception mode is intrusion detection mode and the current judgment is that there is no intrusion, then the perception mode in the configuration information is maintained.

[0256] (3) If the perception mode is intrusion tracking mode and the current judgment is that the intrusion has ended, then change the perception mode in the configuration information to intrusion detection mode.

[0257] (4) If the perception mode is intrusion tracking mode and the current judgment of intrusion has not ended, then the perception mode in the configuration information shall be maintained.

[0258] Based on (1) to (4) above, the state transition (state machine) of the perception mode is as follows:

[0259] The default initialization mode is intrusion detection mode. If this is the first time sensing, the sensing mode is configured as intrusion detection mode; otherwise, the sensing mode is determined as either intrusion detection mode or intrusion tracking mode based on the sensing mode update result. The sensing element determines whether to update the sensing mode (intrusion detection mode or intrusion tracking mode) based on the current judgment result: If the previous state was intrusion detection mode, and the current judgment indicates an intrusion exists, the current state is switched to intrusion tracking mode. If the current judgment indicates no intrusion exists, the current state remains intrusion detection mode. If the previous state was intrusion tracking mode, and the current judgment indicates the intrusion has ended, the current state is switched to intrusion detection mode. If the current judgment indicates the intrusion has not ended, the current state remains intrusion tracking mode.

For example, the sensing reference signal includes reference signals that have been defined by standards, and / or reference signals that have not yet been defined by standards but are used for integrated communication sensing. The reference signals that have been defined by standards include at least one of the following: positioning reference signal (PRS), channel state information reference signal (CSI-RS), and probe reference signal (SRS-Pos) that can be used for 5G positioning.

The sensing receiving device can be a base station (BS) or a terminal (e.g., user equipment (UE), user terminal (UT), etc.). Figure 3 As shown, the method may include, but is not limited to, steps 301 to 304:

[0271] In step 301, configuration information is received, which includes a perception mode and / or perception resources; the perception mode includes an intrusion detection mode and / or an intrusion tracking mode; wherein the perception resources of the intrusion detection mode are less than those of the intrusion tracking mode.

[0272] In this embodiment, the sensing receiving device receives configuration information sent by the sensing network element, wherein the configuration information includes: sensing mode, sensing resources (i.e., time-frequency resources of the sensing reference signal), and at least one of the following (1) to (4):

[0273] (1) The transmission period of the sensing reference signal.

[0274] The transmission period of the sensing reference signal in intrusion detection mode can differ from that in intrusion tracking mode. For example, the transmission period of the sensing reference signal in intrusion detection mode may be longer than that in intrusion tracking mode.

[0275] (2) Perceive the form of the reference signal.

[0276] The form of the sensing reference signal is a reference signal that has been defined by a standard, and / or a reference signal that has not yet been defined by a standard for communication sensing integration.

[0277] (3) The amount reported by the sensing and receiving device.

[0278] In this embodiment, if the perception mode includes an intrusion detection mode, the reported data includes intrusion information. The intrusion information includes at least one of the following:

[0279] Intrusion judgment information, number of intrusion targets, type of intrusion targets, reliability of intrusion judgment, reliability of the number of intrusion targets, and reliability of the type of intrusion targets.

[0280] In this embodiment, if the perception mode includes an intrusion tracking mode, then the reported quantity includes intrusion measurement quantity.

[0281] The intrusion measurement includes at least one of the following:

[0282] The sensing information received by the sensing receiving device includes the number of intrusion targets, the type of intrusion targets, the reliability of the number of intrusion targets, and the reliability of the type of intrusion targets.

[0283] The sensing information of the sensing receiving device includes at least one of the following:

[0284] Raw sensory information, preliminary sensory information, and measurement information.

[0285] The raw sensing information includes, for example, the channel impulse response (CIR). The preliminary sensing information includes, for example, at least one of the time of arrival (TOA) spectrum and the Doppler map. The measurement information includes, for example, at least one of the time of arrival, angle of arrival (AOA), velocity, and Doppler measurements.

[0286] (4) Reporting conditions of sensing and receiving devices.

[0287] In this embodiment, if the sensing mode includes an intrusion tracking mode, the period during which the sensing receiving device sends the reported data is the same as the period during which the sensing reference signal is sent.

[0288] In this embodiment, if the perception mode includes an intrusion detection mode, the reporting conditions include any one of the following A to C:

[0289] A. The sensing receiving device receives the sensing reference signal each time.

[0290] In A, the sensing network element is pre-configured with a historical information collection period to enable the sensing receiving device to collect historical information. During the historical information collection period, the sensing receiving device does not send any reports. After the historical information collection period ends, the period at which the sensing receiving device sends reports is the same as the period at which the sensing reference signal is sent.

[0291] B. The sensing and receiving device receives the sensing reference signal multiple times.

[0292] In B, the period during which the sensing and receiving device transmits the reported data is proportional to the period during which the sensing reference signal is transmitted. For example, H:1 means that the sensing and receiving device transmits intrusion information once after receiving H sensing reference signals. The sensing and receiving device can store historical information for the transmission periods of H sensing reference signals.

[0293] C. When the sensing and receiving device determines that an intrusion has occurred.

[0294] In C, the sensing and receiving device only sends intrusion information when an intrusion is detected, and does not send intrusion information at other times.

[0295] In step 302, a sensing reference signal is received.

[0296] The sensing reference signal is a reference signal that can be used to probe the channel. For example, the sensing reference signal includes reference signals that have been defined by standards, and / or reference signals that have not yet been defined by standards but are used for integrated communication sensing. The reference signals that have been defined by standards include at least one of the following: positioning reference signal (PRS), channel state information reference signal (CSI-RS), and probe reference signal (SRS-Pos) that can be used for 5G positioning.

[0297] In step 303, the reporting quantity corresponding to the sensing mode is determined based on the sensing reference signal.

[0298] In this embodiment, if the perception mode includes an intrusion detection mode, the reported quantity includes intrusion information. The intrusion information includes at least one of the following a to f:

[0299] a. Intrusion judgment information.

[0300] For example, an intrusion decision information of zero indicates no intrusion, while an intrusion decision information of 1 indicates an intrusion has occurred.

[0301] b. Number of targets to be invaded.

[0302] For example, the number of intrusion targets is a positive integer greater than zero, and the resolution is 1.

[0303] c. Type of intrusion target.

[0304] The intrusion target type is used to help determine whether the intrusion target needs to be tracked. For example, an intrusion target type of zero represents a pedestrian, an intrusion target type of 1 represents a car, and an intrusion target type of 2 represents an airplane.

[0305] d. Reliability of intrusion judgment.

[0306] For example, intrusion decision reliability is a value between (0,1) with a resolution of 1 / 2^N, where N is a positive integer. Intrusion decision reliability reflects the degree of trust that the sensing receiving device has in intrusion decision information.

[0307] e. Reliability of the number of intrusion targets.

[0308] For example, the reliability of the number of intrusion targets is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of the number of intrusion targets reflects the degree of trust that the sensing receiving device has in the number of intrusion targets.

[0309] f. Reliability of the type of intrusion target.

[0310] For example, the reliability of an intrusion target type is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of an intrusion target type reflects the degree of trust that the sensing receiving device has in the type of intrusion target.

[0311] In this embodiment, if the sensing mode includes an intrusion detection mode, the sensing receiving device, based on the currently obtained raw sensing information, preliminary sensing information, and / or measurement information, and combined with historical information (i.e., raw sensing information, preliminary sensing information, and / or measurement information measured before the current moment), performs intrusion decision, intrusion target quantity decision, and / or intrusion target type decision, and obtains intrusion decision information and intrusion decision reliability, intrusion target quantity and intrusion target quantity reliability, and intrusion target type and intrusion target type reliability.

[0312] The raw sensing information includes, for example, the channel impulse response (CIR). The preliminary sensing information includes, for example, at least one of the time of arrival (TOA) spectrum and the Doppler map. The measurement information includes, for example, at least one of the time of arrival, angle of arrival (AOA), velocity, and Doppler measurements.

[0313] In this embodiment, if the perception mode includes an intrusion tracking mode, then the reported quantity includes intrusion measurement quantity.

[0314] The intrusion measurement includes at least one of the following:

[0315] The sensing information received by the sensing receiving device includes the number of intrusion targets, the type of intrusion targets, the reliability of the number of intrusion targets, and the reliability of the type of intrusion targets.

[0316] The sensing information of the sensing receiving device includes at least one of the following:

[0317] Raw sensory information, preliminary sensory information, and measurement information.

[0318] In this embodiment, if the perception mode includes an intrusion tracking mode, the perception receiving device, based on the currently obtained raw perception information, preliminary perception information, and / or measurement information, combined with historical information (i.e., raw perception information, preliminary perception information, and / or measurement information measured before the current moment), makes a determination on the number of intrusion targets and the type of intrusion targets, and obtains the intrusion measurement quantity.

[0319] In step 304, the reported quantity is sent.

[0320] In addition to the Time of Arrival (TOA), Time Difference of Arrival (TDOA), Azimuth of Departure (AOD), Zenith of Departure (ZOD), Angle of Arrival (AOA), Zenith of Angle (ZOA), Reference Signal Received Power (RSRP), Reference Signal Received Path Power (RSRPP), Reference Signal Received Quality (RSRQ), and Carrier Phase Positioning (CPP) specified in existing protocols, the reported quantities may also include intrusion information or intrusion measurements described in step 303. Intrusion information or intrusion measurements can be reported simultaneously with TOA, TDOA, AOD, ZOD, AOA, ZOA, RSRP, RSRPP, RSRQ, and CPP, or they can be reported separately.

[0321] In this embodiment, the sensing receiving device sends the reporting amount to the sensing network element based on the reporting conditions.

[0322] In some embodiments, if the sensing mode includes an intrusion detection mode, the sensing receiving device makes an intrusion decision based on the currently obtained raw sensing information, preliminary sensing information and / or measurement information, combined with historical information (i.e., raw sensing information, preliminary sensing information and / or measurement information measured before the current moment), and obtains intrusion decision information and intrusion decision reliability.

[0323] The intrusion judgment methods include any one of the following (1) to (3):

[0324] (1) For the original sensing information (channel impulse response (CIR)), the sensing receiving device can set a historical information buffer period M, which stores the channel impulse responses at times K-1, K-2, ..., KM. Each sampling time can include multiple OFDM symbols. At the current time, when no target is detected, it is foreseeable that its channel impulse response will not change significantly or will fluctuate within a small range. For a new time K, if there is a propagation path from the sensing transmitting device to the intrusion target to the sensing receiving device, then the channel impulse response at time K is significantly different from that at times K-1, K-2, ..., KM, that is, there is an impulse response caused by the propagation path of the intrusion target. The intrusion detection period can also be extended. For example, if the peak spectra at times K, K-1, ..., KL are significantly different from those at times KL-1, ..., KM, then an intrusion is determined to exist. Where L is the detection algorithm window length, and L is an integer greater than or equal to zero. The detection method can be as follows: subtract the CIR values ​​at different times and then draw the power delay profile (PDP) graph. If there is a significant peak, it can be determined that an intrusion has occurred.

[0325] (2) For the initial sensing information (Doppler spectrum) and measurement information (Time of Arrival (TOA), Angle of Arrival (AOA), etc.), the sensing receiving device processes the raw sensing information at each sampling time. For example, it uses the Multiple Signal Classification (MUSIC) algorithm to measure TOA, AOA, velocity, and Doppler to obtain the sensing information. Furthermore, the sensing receiving device can compare the sensing information at times K, K-1, ..., KL with the sensing information at historical times (KL-1, ..., KM). If there are significant differences in the measured values, an intrusion is determined to have occurred. Here, L is the detection algorithm window length, and L is an integer greater than or equal to zero.

[0326] (3) Perform a 2D-FFT transform on the original sensing information (frequency domain channel impulse response) at a certain moment to obtain the range-Doppler map (RDM). If a peak value that is not present in the RDM spectrum at times K, K-1, ..., KL appears in the RDM spectrum at historical times (KL-1, ..., KM), then an intrusion is determined to have occurred. Wherein, L is the detection algorithm window length, and L is an integer greater than or equal to zero.

[0327] The reliability of intrusion determination includes the following (i) or (ii):

[0328] (a) The reliability of a single-moment intrusion decision is:

[0329]

[0330] The `max()` function calculates the maximum value. Measured values ​​can include PDP peak values, TOA, AOA, velocity, etc. For example, for PDP peak values, the intrusion decision reliability is: difference peak amplitude / maximum peak amplitude of the PDP peak spectrum. Other measurements follow a similar pattern.

[0331] (ii) The reliability of intrusion decisions at multiple time points is:

[0332]

[0333] The reliability of both single-moment and multi-moment intrusion decisions is normalized to 1.

[0334] If the historical information caching period M is greater than or equal to 1, the reliability of the intrusion decision at multiple times is reported; otherwise, the reliability of the intrusion decision at a single time is reported.

[0335] In some embodiments, if the sensing mode includes an intrusion detection mode, the sensing receiving device makes a determination of the number of intrusion targets based on the currently obtained raw sensing information, preliminary sensing information and / or measurement information, combined with historical information (i.e., raw sensing information, preliminary sensing information and / or measurement information measured before the current moment), and obtains the number of intrusion targets and the reliability of the number of intrusion targets.

[0336] In this embodiment, a 2D-FFT transform is performed on the frequency domain channel impulse response to obtain the range-Doppler map (RDM). If there are Q peaks in the range-Doppler map that exceed a set threshold ε and are not present in the historical RDM spectrum, then Q intrusion targets are identified. Here, ε is a settable threshold value.

[0337] In this embodiment, the calculation process for the reliability of the number of intrusion targets is as follows:

[0338] Define a threshold value ε1, where ε1 is a percentage, such as 50%. Assuming the amplitude of the maximum peak in the RDM spectrum is V, ε1·V represents 50% of the maximum peak. Compare the values ​​of Q peaks with ε1·V; the number of peaks exceeding ε1·V is Q1 (Q1≤Q), and the reliability of the number of intrusion targets is Q1 / Q. The reliability of the number of intrusion targets is normalized to 1.

[0339] In some embodiments, if the sensing mode includes an intrusion detection mode, the sensing receiving device determines the intrusion target type and the intrusion target type reliability based on the currently obtained raw sensing information, preliminary sensing information and / or measurement information, combined with historical information (i.e., raw sensing information, preliminary sensing information and / or measurement information measured before the current moment).

[0340] The intrusion target type and its reliability can be determined using either method one or method two:

[0341] Method 1: The sensing and receiving device determines the type of intrusion target and the reliability of the intrusion target type.

[0342] Different objects exhibit significant differences in their micro-Doppler characteristics during movement. Micro-Doppler information can be extracted using the velocity projection method from the RDM map, and the target type can be determined by comparing the micro-Doppler features of different objects. For example, the type and reliability of an object can be determined based on commonly used classification algorithms, such as Softmax regression, Support Vector Machine (SVM), and deep learning models. The reliability of an intrusion target type is defined as the probability that the value output by the classification algorithm, ranging from [0,1], belongs to this intrusion target type.

[0343] Method 2: The sensing network element calculates the intrusion target type and reliability based on the calculated intrusion target location and the radar cross section (RCS) characteristics.

[0344] Different objects exhibit significant differences in their RCS (Relative Cross Section) values, which are reflected in path loss. This means that for the same sensing and receiving device, different objects at the same location will have vastly different received signal power. Therefore, the RCS value can be used as a feature to identify different objects. Before intrusion detection, measurements are taken in the detection area for different objects to obtain the path loss or Reference Signal Received Power (RSRP) value of each sensing and receiving device (as fingerprint information). During the intrusion tracking phase, the sensing network element determines the intrusion target type of the current object based on the calculated intrusion target location, the RSRP values ​​reported by each sensing and receiving device, and the fingerprint information, and provides the reliability of the intrusion target type. (The method and approach for determining the intrusion target type and its reliability are the same).

[0345] It should be noted that for Method 2, the sensing and receiving device needs to report the RSRP value. The sensing network element can choose either method, but the amount of data to be reported by the sensing and receiving device differs between the two methods.

[0346] Example

[0347] This embodiment further describes in detail the process of intrusion detection -> target discovery -> target tracking -> intrusion termination -> intrusion detection.

[0348] Intrusion detection → Target discovery process:

[0349] Step 1: Initialization Phase. The sensing network element selects suitable nodes for collaborative sensing based on the sensing area and node sensing capabilities. The initial detection mode is determined to be intrusion detection mode, and corresponding time-frequency resources for sensing reference signals are allocated according to this mode.

[0350] Step 2: The sensing network element sends configuration information to each sensing transmitting device and / or sensing receiving device participating in the collaborative sensing. The configuration information includes: intrusion detection mode, time-frequency resource configuration information for the sensing reference signal, transmission period of the sensing reference signal, form of the sensing reference signal, reporting quantity of the sensing receiving device, and reporting conditions of the sensing receiving device.

[0351] Specifically, the reporting conditions of the sensing and receiving device include any one of the following A to C:

[0352] A. The sensing receiving device receives the sensing reference signal each time.

[0353] In A, the sensing network element is pre-configured with a historical information collection period to enable the sensing receiving device to collect historical information. During the historical information collection period, the sensing receiving device does not send any reports. After the historical information collection period ends, the period at which the sensing receiving device sends reports is the same as the period at which the sensing reference signal is sent.

[0354] B. The sensing and receiving device receives the sensing reference signal multiple times.

[0355] In B, the period during which the sensing and receiving device transmits the reported data is proportional to the period during which the sensing reference signal is transmitted. For example, H:1 means that the sensing and receiving device transmits intrusion information once after receiving H sensing reference signals. The sensing and receiving device can store historical information for the transmission periods of H sensing reference signals.

[0356] C. When the sensing and receiving device determines that an intrusion has occurred.

[0357] In C, the sensing and receiving device only sends intrusion information when an intrusion is detected, and does not send intrusion information at other times.

[0358] Specifically, for intrusion detection mode, intrusion information may include:

[0359] At least one of the following a to f:

[0360] a. Intrusion judgment information.

[0361] For example, an intrusion decision information of zero indicates no intrusion, while an intrusion decision information of 1 indicates an intrusion has occurred.

[0362] b. Number of targets to be invaded.

[0363] For example, the number of intrusion targets is a positive integer greater than zero, and the resolution is 1.

[0364] c. Type of intrusion target.

[0365] The intrusion target type is used to help determine whether the intrusion target needs to be tracked. For example, an intrusion target type of zero represents a pedestrian, an intrusion target type of 1 represents a car, and an intrusion target type of 2 represents an airplane.

[0366] d. Reliability of intrusion judgment.

[0367] For example, intrusion decision reliability is a value between (0,1) with a resolution of 1 / 2^N, where N is a positive integer. Intrusion decision reliability reflects the degree of trust that the sensing receiving device has in intrusion decision information.

[0368] e. Reliability of the number of intrusion targets.

[0369] For example, the reliability of the number of intrusion targets is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of the number of intrusion targets reflects the degree of trust that the sensing receiving device has in the number of intrusion targets.

[0370] f. Reliability of the type of intrusion target.

[0371] For example, the reliability of an intrusion target type is a value between (0,1), with a resolution of 1 / 2^N, where N is a positive integer. The reliability of an intrusion target type reflects the degree of trust that the sensing receiving device has in the type of intrusion target.

[0372] The reporting format of the reported quantity can be [sensing and receiving device identifier, intrusion judgment information, intrusion judgment reliability], or [sensing and receiving device identifier, number of intrusion targets, reliability of the number of intrusion targets, type of intrusion targets, reliability of the type of intrusion targets], or [sensing and receiving device identifier, intrusion judgment information, reliability of intrusion judgment, number of intrusion targets, reliability of the number of intrusion targets, type of intrusion targets, reliability of the type of intrusion targets].

[0373] Intrusion detection information is a mandatory reporting item, while its corresponding reliability is an optional reporting item. All other information and their corresponding reliability are optional reporting items.

[0374] Step 3: The sensing and transmitting device sends a specific form of sensing reference signal at the time and frequency point location of the sensing resource according to the configuration information.

[0375] Step 4: Based on the currently obtained raw sensing information, preliminary sensing information, and / or measurement information, and combined with historical information (i.e., raw sensing information, preliminary sensing information, and / or measurement information measured before the current moment), the sensing and receiving device makes an intrusion decision, an intrusion target quantity decision, and / or an intrusion target type decision, and obtains intrusion decision information and intrusion decision reliability, intrusion target quantity and intrusion target quantity reliability, and intrusion target type and intrusion target type reliability.

[0376] Step 5: The sensing network element determines whether an intrusion has occurred based on the intrusion information reported by the sensing receiving devices. The sensing network element aggregates the intrusion decision information and reliability of the intrusion decisions from each sensing receiving device and performs another intrusion decision; the sensing network element aggregates the number of intrusion targets reported by each sensing receiving device and the reliability of that number, and performs an intrusion target quantity decision; the sensing network element aggregates the intrusion target types reported by each sensing receiving device and the reliability of those types, and performs an intrusion target type decision.

[0377] Step Six: Sensing Element Detection and Sensing Mode State Transition: Assuming an intrusion was determined in Step Five, if the previous state was intrusion detection mode and the current determination is that an intrusion exists, then the current state transitions to intrusion tracking mode.

[0378] Target tracking → Intrusion termination process:

[0379] Step 7: The sensing network element allocates the corresponding time-frequency resources for sensing reference signals according to the intrusion tracking mode, and sends the configuration information to each sensing transmitting / receiving device performing collaborative sensing. The sensing configuration information includes: sensing mode, time-frequency resource allocation for sensing reference signals, transmission period of sensing reference signals, form of sensing reference signals, reporting amount of sensing receiving devices, and reporting conditions of sensing receiving devices.

[0380] Specifically, for intrusion tracking mode: the reported quantity of the sensing receiving device is the intrusion measurement quantity, and the period for the sensing receiving device to send the reported quantity is the same as the period for sending the sensing reference signal.

[0381] Step 8: The sensing and transmitting device transmits a sensing reference signal in a specified form at a specific time and frequency point location, based on the configuration information.

[0382] Step Nine: The amount reported by the sensing and receiving device in intrusion tracking mode is the intrusion measurement quantity. Based on the currently obtained raw sensing information, preliminary sensing information, and / or measurement information, and combined with its own historical information (raw sensing information, preliminary sensing information, and / or measurement information), the sensing and receiving device determines the number and type of intrusion targets, and reports the determination result and the corresponding reliability to the sensing network element.

[0383] Step 10: The sensing network element determines the location, speed, and other information of the intrusion target based on the intrusion measurement data reported by the sensing receiving devices and the locations of each sensing receiving device. The sensing network element then determines the intrusion termination status based on the target tracking location and the number and type of intrusion targets reported by each sensing receiving device. The determination result is either intrusion termination or continued intrusion tracking mode.

[0384] Step 11: Sensing Element Detection and Sensing Mode State Transition: Assuming that the intrusion was determined to have ended in Step 10. If the previous state was intrusion tracking mode and the current judgment is that the intrusion has ended, then the current state transitions to intrusion detection mode.

[0385] Intrusion End → Intrusion Detection Process:

[0386] Repeat steps one through six above.
