[0060] In some embodiments, future Beyond 5G (B5G) and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. Typical applications of ISAC include: navigation and obstacle avoidance for autonomous vehicles, Wi-Fi-based indoor positioning and activity recognition, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has already attracted significant research interest and attention from academia and industry.

[0061] ISAC achieves a low-cost, integrated implementation of communication and sensing functions through shared hardware and software-defined features. Its main characteristics include: a unified and simplified architecture; reconfigurable and scalable functionality; and improved efficiency and reduced costs. The advantages of integrated communication and sensing are threefold: reduced equipment costs and smaller size; improved spectrum utilization; and enhanced system performance.

[0062] Currently, the typical scenarios of integrated communication and sensing that can be realized by upgrading the technology based on the 5G communication system architecture are shown in Table 1 below.

[0063] Table 1:

[0065]

[0066] In some embodiments, depending on the different sensing signal transmitting and receiving nodes, the methods may include, but are not limited to, those mentioned above. Figure 2a The six sensing links shown are... It should be noted that... Figure 2aEach sensing link in the example is illustrated with one sending node and one receiving node. In a real system, different sensing links can be selected according to different sensing requirements. Each sensing link can have one or more sending and receiving nodes, and a real sensing system can include multiple different sensing links. Figure 2a The perception targets in this example are people and vehicles, and it is assumed that neither people nor vehicles carry or have signal receiving / transmitting equipment installed. In reality, the perception targets will be much richer.

[0067] Sensing Link 1: Base station self-transmitting and self-receiving sensing. In this method, the base station sends sensing signals and obtains the sensing results by receiving the echoes of these signals;

[0068] Sensing Link 2: Inter-base station air interface sensing. In this mode, base station 2 receives sensing signals sent by base station 1 and obtains the sensing results.

[0069] Sensing Link 3: Uplink air interface sensing. In this mode, the base station receives sensing signals sent by the terminal and obtains the sensing results.

[0070] Sensing Link 4: Downlink Air Interface Sensing. In this mode, the terminal receives sensing signals sent by the base station and obtains the sensing results.

[0071] Sensing Link 5: Terminal Self-Sending and Receiving Sensing. In this mode, the terminal sends a sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0072] Sensing Link 6: Sidelink sensing between terminals. For example, terminal 2 receives a sensing signal sent by terminal 1 and obtains a sensing result, or terminal 1 receives a sensing signal sent by terminal 2 and obtains a sensing result.

[0073] It should be noted that, Figure 2a Each sensing method is illustrated with a sensing signal transmitter and a sensing signal receiver as an example. In actual systems, one or more different sensing methods can be selected according to different sensing use cases and sensing requirements, and each sensing method can have one or more transmitters and receivers. Figure 2a The perception targets in this example are people and vehicles, and it is assumed that neither people nor vehicles carry or have signal receiving / transmitting equipment installed. In reality, the perception targets will be much richer.

[0074] exist Figure 2aOf the six basic sensing methods shown, in four methods—inter-base station air interface sensing, uplink air interface sensing, downlink air interface sensing, and inter-terminal sidelink sensing—the transmitter and receiver of the sensing signal belong to different devices; that is, these four sensing methods are dual-site sensing. However, in two sensing methods—base station self-transmission and self-reception sensing and terminal self-transmission and self-reception sensing—the transmitter and receiver of the sensing signal belong to the same device; that is, these two sensing methods are single-site sensing.

[0075] Dual-station sensing does not require the equipment to have full-duplex capability, and its signal propagation characteristics are essentially the same as those in existing communication systems. Therefore, dual-station sensing can fully utilize the hardware and signal design of existing communication systems, thus enabling truly integrated communication and sensing design at a lower cost. Furthermore, dual-station sensing, especially uplink or downlink air interface sensing, allows for flexible selection of the terminal equipment responsible for transmitting or receiving sensing signals. If a terminal equipment closer to the sensing target is selected, the signal propagation distance from the target to the terminal is shorter, resulting in lower signal propagation path loss and ultimately a gain in sensing signal power. Based on these advantages, dual-station sensing has remained a hot topic in integrated sensing research.

[0076] However, a significant challenge in dual-station sensing mode is the time-frequency asynchrony between the transmitter and receiver of the sensing signal. The transmitter and receiver each use their respective frequency sources to generate local oscillator and clock signals for transmitting and receiving the sensing signal. The difference between the local oscillator and clock signals between the transceivers leads to timing deviations. For example... Figure 2b As shown, timing deviation includes two parts: timing start point deviation ( Figure 2b Middle τ strat (as shown) and timed drift ( Figure 2b (As shown in Δτ1, Δτ2, Δτ3, etc.). The timing start point deviation is mainly caused by the overall deviation between the receiver clock and the transmitter clock of the sensing signal, resulting in an overall shift in the time delay spectrum. Timing drift, on the other hand, is caused by the difference in clock periods between the receiver clock and the transmitter clock of the sensing signal; as time changes, the timing drift on each OFDM symbol will change.

[0077] The following description, in conjunction with the accompanying drawings, details a state determination method, apparatus, and device provided in this application through some embodiments and application scenarios.

[0078] Please see Figure 3 , Figure 3 This is a flowchart of a state determination method provided in an embodiment of this application, such as... Figure 3 As shown, it includes the following steps:

[0079] Step 301: The first device receives a first signal sent by the second device, the first signal being used for sensing and measurement.

[0080] The first device mentioned above can be a terminal or a network-side device, and the second device mentioned above can be a terminal or a network-side device.

[0081] The first signal mentioned above can be called the sensing signal.

[0082] Step 302: The first device determines the state between the first device and the second device based on the first signal. The state between the first device and the second device is either LOS state or NLOS state.

[0083] The activation or deactivation of the second signal is determined based on the state between the first device and the second device. The second signal is a signal sent by the first device and used to perform round-trip measurements in conjunction with the first signal.

[0084] The aforementioned determination of the state between the first device and the second device based on the first signal can be based on the measurement of some or all symbols of the first signal. Specifically, it determines whether the state between the first device and the second device is a LOS (Low-In, Short-In, No-In, No-In) state. For example, if the first signal includes M symbols in the time domain, after receiving M0 OFDM symbols of the first signal, the first device determines whether the state between the first device and the second device is LOS or NLOS based on the measurement of the M0 OFDM symbols, where 1 ≤ M0 ≤ M.

[0085] In the embodiments of this application, the symbol may refer to an OFDM symbol.

[0086] In some implementations, the time delay spectrum of the first signal can be used to determine whether the first device and the second device are in a LOS (Low-Installation-Outs) or NLOS (Normally Insulated-Outs) state. For example, if a LOS path exists in the time delay spectrum, the first device is determined to be in a LOS state; otherwise, it is determined to be in an NLOS state. Specifically, in one embodiment, the first device can make a judgment based on the time delay spectrum of the first signal and the characteristics of the LOS path. Typically, the path with the strongest power in the LOS path time delay spectrum, and whose time delay value is the smallest among the local peak values ​​of all time delay spectra, can be used to determine whether an LOS path exists. If an LOS path exists, it is in a LOS state; otherwise, it is in an NLOS state. In another embodiment, the first device inputs the time delay spectrum of the first signal into an Artificial Intelligence (AI) model. The AI ​​model outputs a judgment on whether an LOS path exists; if an LOS path exists, it is in a LOS state; otherwise, it is in an NLOS state.

[0087] The second signal mentioned above can be a signal specifically used for round-trip measurements, or the second signal mentioned above can be a reference signal used for communication.

[0088] Among them, the reference signals used for communication can be positioning reference signals (PRS), channel state information reference signals (CSI-RS), sounding reference signals (SRS), and demodulation reference signals (DMRS).

[0089] The activation or deactivation of the second signal can be based on at least one of the first device, the second device, or the third device, depending on the state between the first device and the second device.

[0090] The activation or deactivation of the second signal can be understood as the activation or deactivation of sending the second signal. For example, if the second device or the third device activates the first device to send the second signal, that is, the action of the first device sending the second signal is activated by the second device or the third device. If the second device or the third device deactivates the first device to send the second signal, that is, the action of deactivating the sending of the second signal is indicated by the second device or the third device, specifically, the first device stops or does not send the second signal.

[0091] Alternatively, the activation or deactivation of the second signal can be understood as the activation or deactivation of receiving the second signal. For example, the first device or the third device activates the second device to receive the second signal, that is, the behavior of the second device receiving the second signal is activated by the first device or the third device. For example, the first device or the third device deactivates the second device to receive the second signal, that is, the behavior of deactivating the receiving of the second signal is indicated by the first device or the third device, specifically, the second device stops or does not receive the second signal.

[0092] Alternatively, the activation or deactivation of the second signal can be performed by the first device, the second device, or the third device. For example, if the first device activates the second signal, it sends the second signal to the second device; if the first device deactivates the second signal, it stops or does not send the second signal. If the second device activates the second signal, it receives the second signal; if the second device deactivates the second signal, it stops or does not receive the second signal. If the third device activates the second signal, it notifies the first device to send the second signal to the second device; if the third device deactivates the second signal, it notifies the first device to stop or does not send the second signal.

[0093] The aforementioned round-trip measurement is used to determine or suppress timing start point deviation between the first device and the second device.

[0094] In this embodiment of the application, since the activation or deactivation of the second signal is determined based on the state between the first device and the second device, the continuous transmission of the second signal can be avoided, thereby saving the transmission overhead of the device.

[0095] In addition, in this embodiment, round-trip measurement based on the first signal and the second signal can be supported. The round-trip measurement can determine or suppress the timing start point deviation between the first device and the second device, thereby supporting the determination or suppression of the timing start point deviation between the first device and the second device in the sensing scenario, which is beneficial to improving sensing performance.

[0096] In some implementations, the first device may also select a method to determine or suppress the timing start point deviation between the first device and the second device based on the state between the first device and the second device.

[0097] For example, in LOS (Low-Installation Status) mode, the timing start point deviation between the first and second devices is determined or suppressed based on the LOS path method; in NLOS (Normally Insulated Status) mode, the timing start point deviation between the first and second devices is determined or suppressed based on round-trip measurement. This allows the low-overhead LOS path method to be used in LOS mode, while the high-overhead round-trip measurement method is used only in NLOS mode, thus saving on sensing overhead.

[0098] In some implementations, a LOS path exists in the LOS state. In this scenario, if the location information of the first transceiver is known, the true value of the signal propagation delay corresponding to the LOS path can be determined. Furthermore, in this scenario, the LOS path is the path with the smallest delay and the strongest power. Based on these characteristics, the measured value of the signal propagation delay corresponding to the LOS path can be determined from the delay-Doppler spectrum of the first signal. Therefore, based on the true value and the measured value of the signal propagation delay of the LOS path, the timing start point deviation between the first and second devices can be determined or suppressed.

[0099] In some implementations, the timing start point deviation between the transmitting and receiving ends of the sensing signal in an integrated sensing system can be estimated through round-trip measurements. The basic idea is that, based on the radar "stop-hop" model, the motion state (position and velocity) of the sensed target can be considered unchanged within a short time period (e.g., a few milliseconds to tens of milliseconds). For the same sensed target, the signal propagation delay corresponding to the bidirectional transmission and reception of sensing signals between the transmitting and receiving ends is the same, while the absolute value of the timing start point deviation is the same but the sign is opposite. Therefore, the timing start point deviation between the first and second devices can be determined or suppressed through round-trip measurements.

[0100] Furthermore, round-trip measurements can determine the true values ​​of the signal propagation delays corresponding to the most powerful paths, which may or may not be LOS paths. Simultaneously, the measured values ​​of the signal propagation delays of the most powerful paths can be easily determined based on the delay-Doppler spectrum, thereby enabling the identification or suppression of the impact of timing start point deviations between the first and second devices.

[0101] In this embodiment of the application, the round-trip measurement can be a round-trip time (RTT) measurement, and the method for determining the true value of the signal propagation delay based on the RTT method can be found in the protocol definition, which will not be described in detail here.

[0102] In some implementations, the second signal is activated when the state between the first device and the second device is NLOS, and deactivated when the state between the first device and the second device is LOS. The second signal is a signal sent by the first device and used to perform round-trip measurements in conjunction with the first signal.

[0103] The activation of the second signal can be achieved by the first device activating the first device to send the second signal to the second device, or by the first device receiving a signaling command activating the first device to send the second signal to the second device.

[0104] The above-mentioned activation of the first device to send a second signal to the second device can also be called notifying the first device to send a second signal to the second device, or activating the second signal.

[0105] The deactivation of the second signal can be achieved by the first device deactivating the second signal, that is, the first device stopping or not sending the second signal, or the first device receiving a signaling instruction from the deactivating first device to send the second signal to the second device.

[0106] The above-mentioned deactivation of the first device sending a second signal to the second device can also be called notifying the first device to stop sending a second signal to the second device.

[0107] In the above embodiments, since the second signal is deactivated when the state between the first device and the second device is LOS (Low-Sleep) state, signal transmission overhead can be saved. For example, in the LOS state, the timing start point deviation between the first device and the second device can be determined or suppressed using the LOS path method.

[0108] As an optional implementation, the method further includes:

[0109] The first device sends a first indication message to the second or third device, the first indication message being used to indicate relevant information about the status between the first device and the second device; or

[0110] The first device sends a first signaling message or a second signaling message to the second device. The first signaling message is used to activate the reception of the second signal, and the second signaling message is used to deactivate the reception of the second signal.

[0111] The aforementioned third device can be a terminal or a network-side device. In some embodiments, the aforementioned third device can be a sensing function network element, also called a sensing network element or sensing network function. It can be located on the RAN side or the core network side, referring to a network node in the core network and / or RAN responsible for at least one function such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It can be an upgrade based on AMF or LMF in the 5G network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing function network element can include at least one of the following:

[0112] The system interacts with wireless signal transmitting equipment and / or wireless signal measuring equipment (including the target terminal or the serving base station of the target terminal or the base station associated with the target area) to exchange target information. The target information includes sensing processing requests, sensing capabilities, sensing auxiliary data, sensing measurement types, sensing resource configuration information, etc., in order to obtain the value of the target sensing result or sensing measurement (uplink measurement or downlink measurement) sent by the wireless signal measuring equipment. The wireless signal can also be referred to as the sensing signal.

[0113] The sensing method used is determined based on factors such as the type of sensing service, the information of sensing service consumers, the required Quality of Service (QoS) requirements, the sensing capabilities of the wireless signal transmitting equipment, and the sensing capabilities of the wireless signal measuring equipment. The sensing method may include: base station A transmitting and base station B receiving, or base station transmitting and terminal receiving, or base station A transmitting and receiving, or terminal transmitting and base station receiving, or terminal transmitting and receiving, or terminal A transmitting and terminal B receiving, etc.

[0114] The sensing equipment serving the sensing service is determined based on factors such as the type of sensing service, information of the sensing service consumer, required sensing QoS requirements, sensing capabilities of wireless signal transmitting equipment, and sensing capabilities of wireless signal measuring equipment. The sensing equipment includes wireless signal transmitting equipment and / or wireless signal measuring equipment.

[0115] The overall coordination and scheduling of resources required for managing sensing services, such as the corresponding configuration of sensing resources for base stations and / or terminals;

[0116] The values ​​of the sensed measurements are processed or calculated to obtain the sensing results. Further, the sensing results are verified, and the sensing accuracy is estimated.

[0117] The aforementioned information regarding the state between the first device and the second device may be a specific state between the first device and the second device, such as a LOS state or a NLOS state, or the aforementioned information may indicate whether the state between the first device and the second device has changed.

[0118] By sending the first instruction information to the second or third device, the second or third device can activate or deactivate the transmission of the second signal based on the aforementioned state.

[0119] In some implementations, at least one of the first and second signaling may be downlink control information (DCI), medium access control control element (MAC CE), radio resource control (RRC) signaling, non-access stratum (NAS) signaling, etc.

[0120] The aforementioned first signaling used to activate the reception of the second signal can be understood as the first signaling being used to activate the second signal, or the first signaling being used to activate the act of receiving the second signal.

[0121] The aforementioned second signaling is used to deactivate the reception of the second signal, which can be understood as the second signaling being used to deactivate the second signal, or the second signaling being used to deactivate the act of receiving the second signal.

[0122] In the above embodiments, the activation or deactivation of the second signal by the first device can be achieved through the first signaling or the second signaling. Specifically, based on the state between the first device and the second device, the first signaling for activating the reception of the second signal or the second signaling for deactivating the reception of the second signal can be sent to the second device.

[0123] In some embodiments, the first indication information is used to indicate whether the state between the first device and the second device is a LOS state or a NLOS state; or

[0124] The first indication information is used to indicate a change in the state between the first device and the second device; or

[0125] The first indication information is sent when the state between the first device and the second device is NLOS, and is used to indicate that the state between the first device and the second device is NLOS.

[0126] The aforementioned first indication information can be indicated by one bit to indicate whether the state between the first device and the second device is LOS or NLOS, such as using bit '1' to represent LOS state and bit '0' to represent NLOS state.

[0127] The above indication that the state between the first device and the second device has changed can be understood as sending the first indication information when the state changes. For example, if the first device and the second device were previously considered to be in a LOS state, then when it is determined that the first device and the second device are in a NLOS state, the first indication information is reported; if the first device and the second device were previously considered to be in a NLOS state, then when it is determined that the first device and the second device are in a LOS state, the first indication information is reported.

[0128] At the beginning of the sensing measurement, the first device and the second device can be assumed to be in either LOS or NLOS state. If the first device and the second device are assumed to be in LOS state, the second signal will not be activated at the beginning of the sensing measurement. If the first device and the second device are assumed to be in NLOS state, the second signal will be activated at the beginning of the sensing measurement.

[0129] The aforementioned first indication information is sent when the state between the first device and the second device is NLOS. This can be understood as the first indication information being sent only in NLOS state and not in LOS state, in order to save transmission overhead.

[0130] In some embodiments, when sending the first indication information to the second device, the method further includes at least one of the following:

[0131] When the first indication information indicates that the state between the first device and the second device is NLOS, and the state between the first device and the second device is LOS at the first moment, the first device receives the third signaling sent by the second device, the third signaling being used to activate sending the second signal to the second device;

[0132] When the first indication information indicates that the state between the first device and the second device is in LOS state, and the state between the first device and the second device is in NLOS state at the first moment, the first device receives the fourth signaling sent by the second device, the fourth signaling being used to deactivate the second signal sent to the second device;

[0133] Wherein, the first time is the time before the second time, and the second time is the time corresponding to the state between the first device and the second device indicated by the first indication information.

[0134] The state between the first device and the second device at the first moment mentioned above can be the default state or the state determined in the previous measurement.

[0135] The aforementioned third signaling is used to activate the sending of the second signal to the second device. This can be understood as the second signal being inactive before the third signaling is received, and the third signaling is used to activate the sending of the second signal to the second device; or the aforementioned third signaling being used to activate the sending of the second signal to the second device can be understood as activating the second signal.

[0136] The aforementioned fourth signaling is used to deactivate the sending of the second signal to the second device. This can be understood as the second signal being active before the fourth signaling is received. For example, if the first device sends the second signal to the second device, the fourth signaling is used to deactivate the sending of the second signal to the second device, that is, to notify the first device to stop sending the second signal to the second device; or the aforementioned fourth signaling being used to deactivate the sending of the second signal to the second device can be understood as deactivating the second signal.

[0137] The second moment mentioned above can be the moment when step 302 is executed.

[0138] In the above embodiments, the second signal can be activated or deactivated in a timely manner through the third and fourth signaling to save signal transmission overhead.

[0139] In some implementations, at least one of the aforementioned third and fourth signaling may be DCI, MAC CE, RRC signaling, NAS signaling, etc.

[0140] In some implementations, if the first indication information indicates that the first device and the second device are in an NLOS state, and the first device and the second device are in an NLOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned third signaling or fourth signaling.

[0141] In some implementations, if the first indication information indicates that the first device and the second device are in a LOS state, and the first device and the second device are in a LOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned third signaling or fourth signaling.

[0142] In some embodiments, when sending the first indication information to the third device, the method further includes at least one of the following:

[0143] When the first indication information indicates that the state between the first device and the second device is NLOS, and the state between the first device and the second device is LOS at the first moment, the first device receives the fifth signaling sent by the third device, and the fifth signaling is used to activate the sending of the second signal to the second device;

[0144] When the first indication information indicates that the state between the first device and the second device is in LOS state, and the state between the first device and the second device is in NLOS state at the first moment, the first device receives the sixth signaling sent by the third device, the sixth signaling being used to deactivate the second signal sent to the second device;

[0145] Wherein, the first time is the time before the second time, and the second time is the time corresponding to the state between the first device and the second device indicated by the first indication information.

[0146] The aforementioned fifth signaling is used to activate the sending of the second signal to the second device. This can be understood as the second signal being inactive before the fifth signaling is received, and the fifth signaling is used to activate the sending of the second signal to the second device; or the aforementioned fifth signaling being used to activate the sending of the second signal to the second device can be understood as activating the second signal.

[0147] The aforementioned sixth signaling is used to deactivate the sending of the second signal to the second device. This can be understood as the second signal being active before the sixth signaling is received. For example, if the first device sends the second signal to the second device, the sixth signaling is used to deactivate the sending of the second signal to the second device, that is, to notify the first device to stop sending the second signal to the second device; or the aforementioned sixth signaling being used to deactivate the sending of the second signal to the second device can be understood as deactivating the second signal.

[0148] In the above embodiments, the second signal can be activated or deactivated in a timely manner through the fifth and sixth signaling to save signal transmission overhead.

[0149] In some implementations, at least one of the fifth and sixth signaling signals mentioned above may be DCI, MAC CE, RRC signaling, NAS signaling, etc.

[0150] In some implementations, if the first indication information indicates that the first device and the second device are in an NLOS state, and the first device and the second device are in an NLOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned fifth signaling or sixth signaling.

[0151] In some implementations, if the first indication information is in a LOS state between the first device and the second device, and the first device and the second device are in a LOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned fifth signaling or sixth signaling.

[0152] In some embodiments, the method further includes:

[0153] The first device receives configuration information of the second signal sent by the second device or the third device.

[0156] Waveform types, such as OFDM, SC-FDMA, Orthogonal Time-Frequency-Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signals, etc.

[0157] Subcarrier spacing, for example, 30 kHz in an OFDM system;

[0158] The guard interval can be the time interval between the end of signal transmission and the latest echo signal of that signal being received; this parameter is proportional to the maximum sensing distance; for example, it can be expressed as a 2d... max / c is calculated to obtain d max This refers to the maximum sensing distance (related to sensing requirements), for example, for spontaneously received sensing signals, d max It represents the maximum distance from the sensing signal transceiver point to the signal transmitter point; in some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval.

[0159] Bandwidth, which is inversely proportional to distance resolution, can be obtained by c / (2Δd), where Δd is the distance resolution (related to perception requirements); and c is the speed of light.

[0160] Burst duration, an inversely proportional parameter to rate resolution (related to sensing requirements), represents the time span of the sensed signal and is primarily used to calculate Doppler frequency offset; this parameter can be obtained by c / (2f c Δv) is calculated; where Δv is the velocity resolution; f c It is the carrier frequency of the sensed signal;

[0161] The time-domain interval, this parameter can be obtained by c / (2f c v range ) is calculated; where, v range It is the maximum speed minus the minimum speed (related to sensing requirements); this parameter is the time interval between two adjacent sensing signals;

[0164] Time resources, such as the time slot index or symbol index of the time slot where the sensing signal is located; among them, time resources are divided into two types: one is one-time time resources, such as one symbol sending an omnidirectional sensing signal; the other is non-one-time time resources, such as multiple sets of periodic time resources or discontinuous time resources (which may include start and end times), each set of periodic time resources sends a sensing signal in the same direction, and the beam direction on different sets of periodic time resources is different;

[0165] Frequency resources include the center frequency of the sensed signal, bandwidth, resource block (RB) or subcarrier, reference point (Point A), starting bandwidth location, etc.

[0166] The configuration information for the first device to acquire the second signal may be the configuration information for the first device to receive the second signal sent by the second device or the third device.

[0167] For example, when the first device receives the configuration information of the first signal, it also receives the configuration information of the second signal, such as when the network-side device simultaneously sends the configuration information of the first signal and the second signal to the first device.

[0168] Alternatively, configuration information of the second signal can be received when the second signal is activated.

[0169] In some implementations, the configuration information of the second signal may also be agreed upon by a protocol or pre-configured.

[0170] In some implementations, the first device sending a first signaling message or a second signaling message to the second device includes:

[0171] When the state between the first device and the second device is NLOS, and the state between the first device and the second device is LOS at the first moment, the first device sends the first signaling to the second device; or

[0172] When the state between the first device and the second device is in LOS state, and the state between the first device and the second device is in NLOS state at the first moment, the first device sends the second signaling to the second device;

[0173] Wherein, the first time point is the time point before the third time point, and the third time point is the time point at which the first device determines the state between the first device and the second device.

[0174] In this embodiment, the first device may not report the aforementioned first instruction information, and the first device may activate or deactivate the second signal, such as when the first device is a network-side device.

[0175] In some implementations, the third time point mentioned above and the second time point mentioned above may be the same time point.

[0176] In the above embodiments, the second signal can be activated or deactivated in a timely manner through the first and second signaling to save signal transmission overhead.

[0177] In some implementations, if the first indication information indicates that the first device and the second device are in an NLOS state, and the first device and the second device are in an NLOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned first signaling or second signaling.

[0178] In some implementations, if the first indication information is in a LOS state between the first device and the second device, and the first device and the second device are in a LOS state at a first moment, then no action is taken, that is, in this case, it is not necessary to send the aforementioned first signaling or second signaling.

[0179] In some implementations, the method further includes:

[0180] The first device sends the configuration information of the second signal to the second device.

[0181] The configuration information for the second signal is described in the above-described implementation method and will not be repeated here.

[0182] In this embodiment, configuration information for configuring the second signal by the first device can be implemented.

[0183] In this embodiment, a first device receives a first signal sent by a second device, the first signal being used for sensing and measurement. The first device determines the state between itself and the second device based on the first signal, the state being either a LOS (Low-Input Short-Term) state or a NLOS (Low-Input Short-Term) state. The activation or deactivation of a second signal is determined based on the state between the first and second devices, and the second signal is sent by the first device and used to perform round-trip measurements in conjunction with the first signal. Thus, since the activation or deactivation of the second signal is determined based on the state between the first and second devices, continuous transmission of the second signal can be avoided, saving transmission overhead.

[0221] Optionally, the method further includes:

[0222] The third device sends the configuration information of the second signal to at least one of the first device and the second device.

[0223] It should be noted that this embodiment is as a comparison with... Figure 3 The implementation method of the third device corresponding to the illustrated embodiment can be found in the following examples. Figure 3 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0224] The methods provided in the embodiments of this application are illustrated below through multiple examples:

[0225] Example 1:

[0226] This embodiment describes downlink sensing, where the first device is a terminal and the second device is a base station, specifically including the following:

[0227] The terminal receives the first signal sent by the base station and determines the LOS / NLOS state based on the measurement of some or all OFDM symbols of the first signal.

[0228] The first signal is used to perform sensing measurements. The first signal includes M OFDM symbols in the time domain, where M ≥ 1.

[0229] After receiving M0 OFDM symbols of the first signal, the terminal determines whether the terminal and the base station are in a LOS state or an NLOS state based on the measurement of the M0 OFDM symbols, where 1≤M0≤M.

[0230] In some implementations, after determining the LOS / NLOS state, the terminal has the following options for action:

[0231] Option 1: The terminal reports first indication information to the base station. This first indication information indicates the LOS / NLOS status between the terminal and the base station. For example, the first indication information includes one bit, with bit '1' representing the LOS status and bit '0' representing the NLOS status.

[0232] Option 2: When the LOS / NLOS state between the terminal and the base station changes, the terminal reports the first indication information to the base station, including:

[0233] If the terminal and the base station were previously considered to be in a LOS state, then when the terminal determines that the relationship between the terminal and the base station is in an NLOS state, it reports the first indication information.

[0234] If the terminal and the base station were previously considered to be in an NLOS state, then when the terminal determines that the relationship between the terminal and the base station is in a LOS state, it will report the first indication information.

[0235] It should be noted that at the beginning of the sensing measurement, the terminal and the base station can be assumed to be in either LOS or NLOS state. For example, if the terminal and the base station are assumed to be in LOS state, the second signal will not be activated at the beginning of the sensing measurement; if the terminal and the base station are assumed to be in NLOS state, the second signal will be activated at the beginning of the sensing measurement.

[0236] In some implementations, after receiving the first indication information, the base station performs the following actions depending on its previous state:

[0237] If the first indication information indicates that the terminal and the base station are in an NLOS state, and the terminal and the base station were previously considered to be in a LOS state, then the base station sends a third signaling to the terminal. The third signaling is used to notify (or activate) the terminal to send a second signal to the base station.

[0238] If the first indication information indicates that the terminal and the base station are in a LOS state, and the terminal and the base station were previously considered to be in a NLOS state (i.e., the second signal is in an active state), then the base station sends a fourth signaling to the terminal, which is used to notify the terminal to stop (or deactivate) the second signal sent to the base station.

[0239] If the first indication information indicates that the terminal and the base station are in an NLOS state, and the terminal and the base station were previously considered to be in an NLOS state (i.e., the second signal is in an active state), then no action is taken;

[0240] If the first indication message indicates that the terminal and the base station are in a state of LOS, and the terminal and the base station were previously considered to be in a state of LOS, then no action is taken.

[0241] The state between the terminal and the base station mentioned above refers to the state between the terminal and the base station at the first moment in the above embodiment.

[0242] Furthermore, the previous state where the terminal and the base station were considered to be in NLOS or LOS could be the default state at the beginning of the sensing measurement, or it could be determined by the first indication information reported by the terminal to the base station during the previous sensing process.

[0243] In some implementations, the aforementioned third and / or fourth signaling may be DCI, MAC CE, RRC signaling, NAS signaling, etc.

[0244] In some implementations, the second signal is used in conjunction with the first signal to perform round-trip measurements, and is used to extract or suppress the timing start point deviation experienced by the first signal received by the terminal.

[0245] In some implementations, the base station sends configuration information for the second signal to the terminal before the terminal sends the second signal to the base station.

[0246] Specifically, before the base station sends the first signal, when the base station sends the configuration information of the first signal to the terminal, it also sends the configuration information of the second signal to the terminal at the same time; however, the transmission of the second signal is not activated, only the transmission of the first signal is activated.

[0247] Alternatively, after receiving the first instruction information, the base station sends the configuration information of the second signal to the terminal and activates the transmission of the second signal.

[0248] Clearly, sending the configuration information for the second signal simultaneously with the configuration information for the first signal is the preferred approach. This is because sending the configuration information for the second signal via RRC signaling would incur a significant end-to-end delay.

[0249] Example 2:

[0250] This embodiment describes uplink sensing. In this embodiment, the first device is a base station and the second device is a terminal, specifically including the following:

[0251] The base station receives the first signal sent by the terminal and determines the LOS / NLOS state based on the measurement of some or all OFDM symbols of the first signal.

[0252] The first signal is used to perform sensing measurements. The first signal includes M OFDM symbols in the time domain, where M ≥ 1.

[0253] After receiving M0 OFDM symbols of the first signal, the base station determines whether the terminal and the base station are in a LOS state or an NLOS state based on the measurement of the M0 OFDM symbols, where 1≤M0≤M.

[0254] In some implementations, after the base station determines the LOS / NLOS state between the terminal and the base station, the following actions are performed:

[0255] If the base station determines that the terminal and the base station are in an NLOS state, and the terminal and the base station were previously considered to be in a LOS state, the base station sends a first signaling to the terminal. The first signaling is used to notify (or activate) the terminal to receive the second signal sent by the base station.

[0256] If the base station determines that the terminal and the base station are in a LOS state, and the terminal and the base station were previously considered to be in a NLOS state (i.e., the second signal is in an active state), the base station sends a second signaling to the terminal. The second signaling is used to notify the terminal to stop (or deactivate) receiving the second signal sent by the base station.

[0257] If the base station determines that the terminal and the base station are in an NLOS state, and the terminal and the base station were previously considered to be in an NLOS state (i.e., the second signal is in an active state), then no action is taken;

[0258] If the base station determines that the terminal and the base station are in a LOS state, and the terminal and the base station were previously considered to be in a LOS state, then no action is taken.

[0259] The state between the terminal and the base station mentioned above refers to the state between the terminal and the base station at the first moment in the above embodiment.

[0260] The aforementioned first signaling and / or second signaling can be DCI, MAC CE, RRC signaling, NAS signaling, etc.

[0261] The second signal is used to configure the first signal to perform round-trip measurements, and to extract or suppress the timing start point deviation experienced by the first signal received by the base station.

[0262] The aforementioned state where the terminal and base station were previously considered to be in NLOS or LOS state can be the default state at the beginning of the sensing measurement, or it can be determined by the base station during the previous sensing process.

[0263] In some implementations, the base station sends configuration information for the second signal to the terminal before sending the second signal to the terminal.

[0264] Specifically, it could be:

[0265] Before the base station sends the first signal, when the base station sends the configuration information of the first signal to the terminal, it also sends the configuration information of the second signal to the terminal at the same time; however, the transmission of the second signal is not activated, only the transmission of the first signal is activated.

[0266] Alternatively, after receiving the first instruction information, the base station sends the configuration information of the second signal to the terminal and activates the transmission of the second signal.

[0267] Clearly, sending the configuration information for the second signal simultaneously with the configuration information for the first signal is the preferred approach. This is because sending the configuration information for the second signal via RRC signaling would incur a significant end-to-end delay.

[0268] Example 3:

[0269] This embodiment describes sidelink sensing or inter-base station sensing, and specifically includes the following:

[0270] The first device receives a first signal sent by the second device and determines the LOS / NLOS state based on the measurement of some or all OFDM symbols of the first signal.

[0271] The first signal is used to perform sensing measurements, and the first signal includes M OFDM symbols in the time domain, where M ≥ 1.

[0272] After receiving M0 OFDM symbols of the first signal, the first device determines whether the first device and the second device are in a LOS state or an NLOS state based on the measurement of the M0 OFDM symbols, where 1≤M0≤M.

[0273] In the case of sidelink awareness, the first device is terminal 1 and the second device is terminal 2.

[0274] In the case of inter-base station sensing, the first device is base station 1 and the second device is base station 2.

[0275] In some implementations, after determining the LOS / NLOS status, the first device may perform one of the following actions:

[0276] Option 1: The first device reports first indication information to the sensing function network element (i.e., the third device in the above embodiment). The first indication information is used to indicate the LOS / NLOS state between the first device and the second device. For example, the first indication information includes one bit, with bit '1' representing the LOS state and bit '0' representing the NLOS state.

[0277] Option 2: In NLOS state, the first device reports the first indication information to the sensing function network element; in LOS state, the first device does not report the first indication information. Here, the first indication information is used to indicate that the first device and the second device are in NLOS state.

[0278] In the case of sidelink sensing, the sensing function network element can be a base station.

[0279] In the case of inter-base station sensing, the sensing function network element can be a core network device.

[0280] In some implementations, after receiving the first instruction information, the sensing function network element has the following action options:

[0281] If the first indication information indicates that the first device and the second device are in an NLOS state, and the first device and the second device were previously considered to be in a LOS state, then the sensing function network element sends a fifth signaling and a seventh signaling to the first device and the second device respectively. The fifth signaling is used to notify (or activate) the first device to send a second signal to the second device, that is, to activate the first device to send a second signal, and the seventh signaling is used to activate the second device to receive the second signal.

[0282] If the first indication information indicates that the first device and the second device are in a LOS state, and the first device and the second device were previously considered to be in a NLOS state (i.e., the second signal is in an activated state), then the sensing function network element sends a sixth signaling and an eighth signaling to the first device and the second device, respectively. The sixth signaling is used to notify the first device to stop (or deactivate) sending the second signal to the second device, and the eighth signaling is used to notify the second device to stop receiving the second signal.

[0283] If the first indication indicates that the first device and the second device are in an NLOS state, and the first device and the second device were previously considered to be in an NLOS state (i.e., the second signal is in an active state), then no action is taken;

[0284] If the first indication message indicates that the first device and the second device are in a state of LOS, and the first device and the second device were previously considered to be in a state of LOS, then no action is taken;

[0285] The state between the terminal and the base station mentioned above refers to the state between the terminal and the base station at the first moment in the above embodiment.

[0286] The second signal is used to perform round-trip measurements in conjunction with the first signal, and is used to extract or suppress the timing start point deviation experienced by the first signal received by the first device.

[0287] In the case of sidelink awareness, at least one of the above-mentioned fifth, sixth, seventh, and eighth signaling can be DCI, MAC CE, RRC signaling, NAS signaling, etc.

[0288] The aforementioned state where the first and second devices were previously considered to be in NLOS or LOS states can be the default state at the beginning of the sensing measurement, or it can be determined by the first indication information reported by the first device to the sensing function network element during the previous sensing process.

[0289] In some implementations, the sensing function network element sends configuration information for the second signal to the first device and the second device before the first device sends the second signal to the second device.

[0290] Specifically, it can be:

[0291] Before the second device sends the first signal, when the sensing function network element sends the configuration information of the first signal to the first device and the second device, it also sends the configuration information of the second signal to the first device and the second device; however, the transmission of the second signal is not activated, only the transmission of the first signal is activated;

[0292] Alternatively, after the sensing function network element receives the first indication information, the sensing function network element sends the configuration information of the second signal to the first device and the second device and activates the transmission of the second signal.

[0293] Obviously, it is a preferred solution to send the configuration information of the second signal together when the sensing function network element sends the configuration information of the first signal. Because sending the configuration information of the second signal will have a relatively large end-to-end delay.

[0294] Embodiment 4:

[0295] In this embodiment, the typical implementation manners of the method provided in the embodiments of the present application are mainly described.

[0296] This embodiment shows several typical implementation methods to facilitate the understanding of the solutions described in the previous embodiments.

[0297] As described above, the first signal is used to perform sensing measurement, and the second signal is used to configure the first signal to perform round-trip measurement to suppress or extract the timing start point deviation suffered by the first signal.

[0298] The time domain span of the first signal for performing a sensing measurement once and obtaining a sensing result is called the coherent processing interval (CPI) or sensing frame. One CPI or sensing frame occupies M OFDM symbols in the time domain, M>1. During the duration of one CPI, the method provided in the embodiments of the present application can be executed in one of the following ways:

[0299] Mode 1: Determine the LOS / NLOS state after M0 (M0<M) OFDM symbols, and activate or deactivate the second signal within the duration of the current CPI, as Figure 6 shown in 3(a) of

[0300] In some implementation manners, measuring one or more OFDM symbols is sufficient to determine the LOS / NLOS state, and then the second signal can be activated or deactivated within the current CPI of the first signal. Since one CPI is usually on the order of ten milliseconds to one hundred milliseconds, this operation is usually achievable.

[0301] The advantage of this operating method is that timing start point deviation can be suppressed or extracted based on the second signal at the current CPI.

[0302] Method 2: Determine the LOS / NLOS state after M OFDM symbols, and activate or deactivate the second signal within a short period after the current CPI duration, such as... Figure 6 As shown in (b) of the diagram.

[0303] In some implementations, the first device needs to receive the first signal of a CPI before it can perform calculations related to the determination of the LOS / NLOS state. Then, it can activate or deactivate the second signal. The second signal is measured back and forth with the first signal of the current CPI to extract or suppress the timing start point deviation.

[0304] In some cases, such as when the timing drift of the first and second devices is small, the second signal within a certain time after the first signal of a CPI can suppress or extract the timing start point deviation with sufficient accuracy from the first signal of the current CPI.

[0305] Method 3: Determine the LOS / NLOS state after M OFDM symbols, and activate or deactivate the second signal within the next CPI, such as... Figure 6 As shown in (c) in the figure.

[0306] It should be noted that the first device in this embodiment can be: the terminal in embodiment one, the base station in embodiment two, or terminal 1 or base station 1 in embodiment three. The second device in this embodiment can be: the base station in embodiment one, the terminal in embodiment two, or terminal 2 or base station 2 in embodiment three.
