Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0153] In some embodiments, the sensing system integrates a radar system on top of a communication system in related technologies, and senses information such as the distance, speed, and angle of targets in the surrounding environment by sending sensing signals. As shown in Figure 1B, sensing systems can generally be divided into two types according to their sensing modes. The first type is mono-static sensing mode, where the transceiver can be an access network device or a terminal. The second type is bi-static sensing mode, where the transmitter can be an access network device or a terminal, and the receiver can be both an access network device and a terminal.

[0154] In communication beam management, the selection of transmit and receive beam pairs is usually completed based on three processes: P1, P2, and P3. For example, in the downlink beam management process P1, the access network device uses the same transmit beam to send a set of different reference signals. The terminal uses different receive beams to receive the reference signals and measures parameters such as layer 1 (L1) reference signal receive power (RSRP) / signal-to-interference ratio (SINR). The access network device switches to another transmit beam and repeats the above process. After the access network device has traversed the transmit beams, the terminal reports the reference signal ID corresponding to the highest L1-RSRP / SINR, thereby determining the optimal initial transmit / receive beam pair. In the downlink beam management process P2, the access network device sends different reference signals through different narrow beams within the wide transmit beam envelope determined in the P1 process. The terminal uses a fixed receive beam to receive the reference signals and measures parameters such as L1-RSRP / SINR. The terminal reports the reference signal ID corresponding to the highest L1-RSRP / SINR, thereby determining the optimal narrow transmit beam and completing the transmit beam improvement. However, in sensing systems, the frequency domain resources occupied by the sensing reference signal affect the range sensing resolution. Existing reference signals are usually comb-shaped. On the one hand, a larger bandwidth occupied by the sensing reference signal will bring better range sensing resolution, but also more overhead. On the other hand, reducing the frequency domain symbol density will lead to a smaller maximum unambiguous range estimate. Therefore, it is necessary to consider a new sensing scanning mode that can accurately identify the sensing target and complete sensing transmit / receive beam pairing, while also reducing beam scanning delay to a certain extent and ensuring delay / Doppler sensing accuracy during beam scanning.

[0155] In related technologies, there is still no solution for how to determine the sensing reference signal resources that can sense the sensing target in a sensing system, which is an urgent problem to be solved.

[0156] Based on this, this disclosure provides a sensing method and apparatus, wherein the method executed by a first device includes: determining sensing reference signal resources for a sensing reference signal; and transmitting a sensing reference signal based on the sensing reference signal resources. Thus, the first device can determine the sensing reference signal resources for the sensing reference signal and transmit the sensing reference signal based on the determined sensing reference signal resources, enabling accurate sensing of the sensing target and improving the performance of the sensing system.

The sensing reference signal sent by the first device is used to sense the sensing target.

[0167] In some embodiments, the sensing reference signal resources include time-domain resources, frequency-domain resources, etc.

[0168] In some embodiments, the first configuration information is used to indicate one or more sensing transmit beams of the sensing reference signal.

[0183] For example, the first configuration information is used to indicate that the first value is 5, that is, the first configuration information is used to indicate that the number of sensing reference signal resources is 5.

[0184] In some embodiments, the first configuration information is used to indicate the number of sensing reference signal resource groups.

[0185] For example, the first configuration information is used to indicate that the second value is 2, that is, the first configuration information is used to indicate that the number of sensing reference signal resource groups is 2.

[0186] In some embodiments, the first configuration information is used to indicate the number of sensing reference signal resources in each sensing reference signal resource group.

That is, the first configuration information is used to indicate that the number of sensing reference signal resources is 5 and the number of sensing reference signal resource groups is 2, wherein the number of sensing reference signal resources in one sensing reference signal resource group is 3 and the number of sensing reference signal resources in the other sensing reference signal resource group is 2.

[0188] In some embodiments, the first configuration information is used to indicate the number of time-domain symbols occupied by each sensing reference signal resource.

[0189] For example, the first configuration information is used to indicate a first value of 5 and a fourth value of 2, that is, the first configuration information is used to indicate 5 sensing reference signal resources, and the number of time domain symbols occupied by each sensing reference signal resource is 2.

[0190] For example, the first configuration information is used to indicate that the first value is 5 and the fourth value is 1, 2, 2, 2, 2. That is, the first configuration information is used to indicate 5 sensing reference signal resources, and the number of time domain symbols occupied by the first sensing reference signal resource is 1, while the number of time domain symbols occupied by the remaining sensing reference signal resources is 2.

[0191] In some embodiments, the first configuration information is used to indicate the time-domain symbol index corresponding to the sensing reference signal resource.

[0192] For example, the first configuration information is used to indicate that the first value is 3 and the second value is 1, 8, 2, 9, 3, 10. This allows the identification of three sensing reference signal resources, where the time-domain symbol index corresponding to the first sensing reference signal resource is {1, 8}, the time-domain symbol index corresponding to the second sensing reference signal resource is {2, 9}, and the time-domain symbol index corresponding to the third sensing reference signal resource is {3, 10}.

[0193] In some embodiments, the first configuration information is used to indicate the interval between two adjacent sensing reference signal resources among a plurality of sensing reference signal resources.

[0194] For example, if the first configuration information is used to indicate that the first value is 14, then the interval between two adjacent sensing reference signal resources in a plurality of sensing reference signal resources can be determined to be 14 time-domain symbols.

[0195] In some embodiments, the first configuration information is used to indicate the time-domain symbol index corresponding to the first sensing reference signal arranged in the time domain in each sensing reference signal resource group.

[0196] For example, if the first configuration information is used to indicate that the first value is 2 or 16, then two sensing reference signal resource groups can be determined, wherein the time domain symbol index corresponding to the first sensing reference signal arranged in the time domain in the first sensing reference signal resource group is 2, and the time domain symbol index corresponding to the first sensing reference signal arranged in the time domain in the other sensing reference signal resource group is 16.

[0197] In some embodiments, the first configuration information is used to indicate the interval between two adjacent time-domain symbols in a plurality of time-domain symbols occupied by the sensing reference signal.

[0198] For example, if the first configuration information is used to indicate that the first value is 7, then it can be determined that the interval between two adjacent time domain symbols in the multiple time domain symbols occupied by the sensing reference signal is 7.

[0199] In some embodiments, the first configuration information is used to indicate the interval between two adjacent sensing reference signal resource groups in a plurality of sensing reference signal resource groups.

[0200] For example, if the first configuration information is used to indicate that the first value is 7, then the interval between two adjacent sensing reference signal resource groups in a plurality of sensing reference signal resource groups can be determined to be 7.

[0201] In some embodiments, the first configuration information is used to indicate the time slot index corresponding to the sensing reference signal resource.

[0202] For example, the first configuration information is used to indicate that the first value is 3 and the second value is 1, 8, 2, 9, 3, 10. This allows the determination of three sensing reference signal resources, where the time slot index corresponding to the first sensing reference signal resource is {1, 8}, the time slot index corresponding to the second sensing reference signal resource is {2, 9}, and the time slot index corresponding to the third sensing reference signal resource is {3, 10}.

[0203] In some embodiments, the first configuration information is used to indicate the time slot index corresponding to the sensing reference signal resource group.

[0204] For example, the first configuration information is used to indicate that the first value is 0 or 3. This allows for the identification of two sensing reference signal resource groups, where the first sensing reference signal resource group corresponds to a time slot index of 0, and the second sensing reference signal resource group corresponds to a time slot index of 3.

[0205] In some embodiments, the first configuration information is used to indicate the time-domain symbol index corresponding to the sensing reference signal in each sensing reference signal resource group.

[0206] In some embodiments, the time-domain symbol index corresponding to the sensing reference signal in the i-th sensing reference signal resource group is k. i =s i+n i Δ i +m i +iT;

[0207] Among them, s i The starting time-domain symbol index is the first sensing reference signal resource in the i-th sensing reference signal resource group, sorted by time domain.

[0208] n i Let be the time-domain symbol index of the sensing reference signal resource in the i-th sensing reference signal resource group;

[0209] Δ i The interval between two adjacent time-domain symbols in the multiple time-domain symbols occupied by the sensing reference signal resources in the i-th sensing reference signal resource group;

[0210] m i Let be the time-domain symbol index of the sensing reference signal in the i-th sensing reference signal resource group;

[0211] T is the interval between two adjacent sensing reference signal resource groups.

[0212] For example, as shown in FIG3, the first configuration information is used to indicate s i =2,n i =0,1,Δ i =7,m iGiven that the values ​​are 0, 1, 2, T = 14, and i = 0, 1, the time-domain (orthogonal frequency division multiplexing, OFDM) symbol index of the sensing reference signal in the i = 0 sensing reference signal resource group is {2, 3, 4, 9, 10, 11}, and the time-domain symbol index of the sensing reference signal in the i = 1 sensing reference signal resource group is {16, 17, 18, 23, 24, 25}. The sensing reference signal resources are divided into two sensing reference signal resource groups, each covering multiple different directions, and the sensing transmission directions corresponding to the two sensing reference signal resource groups are different. Three sensing reference signal resources are configured in the first sensing reference signal resource group, corresponding to RS#0, RS#1, and RS#2 respectively. Each sensing reference signal occupies two time-domain symbols, and the interval between the two time-domain symbols is seven time-domain symbols. The three sensing reference signals are transmitted sequentially. Three sensing reference signal resources are configured within the second sensing reference signal resource group, corresponding to RS#3, RS#4, and RS#5 respectively. Each sensing reference signal occupies two time-domain symbols, with a seven-time-domain symbol interval between the two time-domain symbols. The three sensing reference signals are transmitted sequentially. In this case, since the two time-domain symbol spans corresponding to the sensing reference signal resource of each sensing transmission beam are relatively long, the Doppler measurement accuracy can be improved to a certain extent.

[0213] In some embodiments, the sensed reference signal resource includes at least one of the following: time-domain resource; frequency-domain resource; power information; periodic information; quasi-co-location (QCL) information.

Optionally, the period information of the sensing reference signal can be information about sensing reference signal resource groups, that is, the number of sensing reference signal periods corresponds to the number of sensing reference signal resource groups.

[0218] In some embodiments, the first configuration information is used to indicate the QCL information of the sensing reference signal.

[0222] For example, when the second device determines, either independently or based on a protocol agreement, that it needs to configure sensing reference signal resources for the first device to send sensing reference signals, it determines to send first configuration information to the first device.

[0223] For example, when the second device receives a request from the first device requesting the second device to configure sensing reference signal resources for transmitting sensing reference signals to the first device, it determines to send first configuration information to the first device.

[0224] S202A, the first device determines the sensing reference signal resource of the sensing reference signal.

[0227] In some embodiments, the first device receives first configuration information sent by the second device. When the first configuration information indicates a sensing reference signal resource for a sensing reference signal, the sensing reference signal resource can be determined based on the first configuration information. The sensing reference signal resource indicated by the first configuration information sent by the second device is a resource capable of sensing a sensing target. Therefore, when the first device sends a sensing reference signal based on the first configuration information of the second device, it can accurately sense the sensing target, thereby improving the performance of the sensing system.

[0235] In some embodiments, the second configuration information is used to indicate the measurement result of the first parameter to be sent to the second device.

[0236] In some embodiments, the first parameter includes at least one of the following: time delay; Doppler frequency.

[0245] In this embodiment of the present disclosure, the second device instructs the first device to send the measurement results of the first parameter within the time window length. Since the time window length is determined by the second device based on the sensing reference signal resources, the sensing reference signal can be accurately received within the time window length, enabling accurate sensing of the sensing target and improving the performance of the sensing system.

[0246] In some embodiments, the second device determines to send the second configuration information to the first device on its own, or the second device determines to send the second configuration information to the first device based on the instruction of the first device, or determines to send the second configuration information to the first device based on the agreement.

[0247] For example, if the second device determines on its own or based on the agreement that it needs to obtain the measurement results of the first parameter, it determines to send the second configuration information to the first device.

[0248] For example, if the second device receives an instruction from the first device indicating that the first device has obtained the measurement result of the first parameter, the second device determines to send the second configuration information to the first device.

After being reflected by the sensing target, the signal is received by the first device. That is, the first device is capable of receiving the sensing reference signal transmitted by the first device based on the sensing reference signal resources.

[0252] S205A, the first device measures the sensing reference signal and determines the measurement result of the first parameter.

[0253] In some embodiments, the first device receives second configuration information sent by the second device, and measures the received sensing reference signal sent by the first device according to the sensing reference signal resource to determine the measurement result of the first parameter.

[0264] For example, as shown in Figure 3, a schematic diagram of the sensing reference signal resources is presented, where each sensing reference signal occupies two time-domain symbols. Since the span of the two time-domain symbols occupied by the sensing reference signal resources corresponding to each sensing transmit beam is relatively long, it can improve the Doppler measurement accuracy to a certain extent.

[0265] In one possible implementation, the second device can be configured to measure only the time delay and not the Doppler frequency. The second device can determine the distance information of the sensing target and the path passing through the sensing target and / or the optimal sensing transceiver beam pair based solely on the time delay measurement results.

[0295] In some embodiments, the third device autonomously implements the function indicated by the second configuration information, or the above function is a default or default value, in which case S203B can be omitted.

[0296] In some embodiments, the second configuration information is used to indicate the measurement result of the first parameter to be sent to the second device.

[0297] In some embodiments, the first parameter includes at least one of the following: time delay; Doppler frequency.

[0298] In this embodiment of the disclosure, the second configuration information is used to instruct the third device to send the delay measurement results to the second device.

[0299] In this embodiment of the disclosure, the second configuration information is used to instruct the third device to send the measurement results of the Doppler frequency to the second device.

[0300] In this embodiment of the disclosure, the second configuration information is used to instruct the third device to send the measurement results of the delay and Doppler frequency to the second device.

[0312] In some embodiments, the first device and the third device employ a dual-station sensing method. The first device transmits a sensing reference signal based on sensing reference signal resources, which is then received by the third device after being scattered and / or reflected by the sensing target. In other words, the third device is capable of receiving the sensing reference signal transmitted by the first device based on the sensing reference signal resources.

[0314] In some embodiments, the third device receives second configuration information sent by the second device, and measures the received sensing reference signal sent by the first device based on the sensing reference signal resource to determine the measurement result of the first parameter.

[0315] In some embodiments, the third device measures the sensed reference signal to determine the measurement result of the time delay.

[0316] In some embodiments, a third device measures the sensed reference signal to determine the measurement result of the Doppler frequency.

[0317] In some embodiments, the third device measures the sensed reference signal to determine the measurement results of time delay and Doppler frequency.

[0318] S206B, the third device sends the measurement result of the first parameter to the second device.

[0319] In some embodiments, the second device receives the measurement result of the first parameter sent by the third device, but is not limited thereto. The second device may also receive the measurement result of the first parameter sent by other entities other than the third device, in which case S206B can be omitted.

Since the span of the two time-domain symbols occupied by the sensing reference signal resources corresponding to each sensing transmit beam is relatively long, it can improve the Doppler measurement accuracy to a certain extent.

[0326] In one possible implementation, the second device can be configured to measure only the time delay and not the Doppler frequency. The second device can determine the distance information of the sensing target and the path passing through the sensing target and / or the optimal sensing transceiver beam pair based solely on the time delay measurement results.

The second device can determine the distance information of the sensing target and the path passing through the sensing target and / or the optimal sensing transceiver beam pair based solely on the measurement results of the Doppler frequency.

[0328] In another possible implementation, the second device can be configured to measure the time delay and Doppler frequency of the first device. Based on the measurement results of the time delay and Doppler frequency, the second device can determine the distance information of the sensing target, determine the path passing through the sensing target and / or the optimal sensing transceiver beam pair.

[0431] To facilitate understanding of the embodiments of this disclosure, an exemplary embodiment is provided.

[0432] In an exemplary embodiment, a sensing method is proposed, specifically a sensing beam scanning method, which ensures the accuracy of Doppler estimation while effectively estimating the sensing target.

[0433] In a sensing system, it is necessary to acquire information such as distance (time delay), velocity (Doppler), and angle related to the sensing target. The sensing receiver receives the sensing signal and acquires the relevant information of the sensing target based on the sensing algorithm, and reports it to the sensing node. The sensing node can be a high-level node with the ability to process sensing data, such as a sensing management entity or a sensing function node. The sensing node can determine whether there is a sensing target in the current environment, and whether a certain sensing transmit beam, sensing receive beam, or sensing transmit / receive beam pair carries the relevant information of the sensing target on a certain path, based on the sensing information reported by each sensing receiver.

[0434] Sensing systems typically require an initial beam scan between the sensing transceivers to determine the initial sensing transceiver beam pairs and make a preliminary assessment of the presence of the sensing target. Generally, to reduce the latency of sensing beam scanning, latency estimation can be considered only during beam scanning, or a combination of latency estimation and low-precision Doppler estimation can be used. However, low-precision Doppler estimation reduces the accuracy of beam pair selection during sensing beam scanning. Therefore, designing a high-precision Doppler estimation method that also reduces beam scanning latency is a problem that needs to be considered.

[0435] Step 1: Configure the sensing reference signal resources for time delay and Doppler estimation:

[0436] The sensing reference signal resource set contains one or more subsets of sensing reference signal resources;

[0437] Each subset of sensing reference signal resources includes one or more sensing reference signal resources;

[0438] Each subset of sensing reference signal resources occupies different temporal domain resources in sequence;

[0439] The temporal resources occupied by each sensing reference signal resource within each subset of sensing reference signals can be configured according to the required Doppler measurement resolution and accuracy. For example, the temporal resources have a large temporal duration, i.e., a relatively long Doppler measurement time window.

[0440] Step 2: During sensing beam scanning, the sensing transceiver can be configured via the network or sensing nodes to perform delay and Doppler estimation. For example, using the sensing reference signal resources configured in Step 1 can support high-precision Doppler estimation.

[0441] Within the time-domain resources corresponding to a subset of sensing reference signal resources, multiple sensing transmit beams sequentially and periodically transmit sensing reference signals.

[0442] It should be understood that steps 1 and 2 above can be applied to steps such as initial determination of the sensing transmit / receive beam pair and improvement of the sensing transmit / receive beam pair.

[0443] It should be understood that multiple beams need to be transmitted in a time-division multiplexing manner within a subset of sensing reference signal resources. In order to ensure the maximum unambiguous frequency of Doppler estimation, the number of reusable beams is relatively small. Therefore, multiple time-division multiplexed subsets of sensing reference signals are used to support scanning beams in more directions.

[0444] For example, as shown in Figure 3, in the sensing transmit beam scanning, the sensing transmit beam is divided into two subsets, each covering multiple different directions, and the sensing transmit directions corresponding to the two sensing transmit beam subsets are different. In the first cycle, three sensing reference signal resources are configured, corresponding to RS#0, RS#1, and RS#2 respectively. Each sensing reference signal occupies two OFDM symbols, and the interval between the two OFDM symbols is seven OFDM symbols. The three sensing reference signals are transmitted sequentially. In the second cycle, three sensing reference signal resources are configured, corresponding to RS#3, RS#4, and RS#5 respectively. Each sensing reference signal occupies two OFDM symbols, and the interval between the two OFDM symbols is seven OFDM symbols. The three sensing reference signals are transmitted sequentially. At this time, because the span between the two OFDM symbols corresponding to the time domain resources of each beam's reference signal is relatively long, the Doppler measurement accuracy is improved to a certain extent. The receiving end sensing receiver can measure the path delay and Doppler. Correspondingly, the sensing node can determine the path of the sensing target and the optimal sensing transmit beam pair through distance and velocity information.

[0445] The configuration information related to the method used in this embodiment is as follows:

[0446] Sensing beam scanning based on time delay and Doppler. For a sensing receiver, network, or sensing node, configure the time-domain resources, power information, QCL information, etc., of the sensing reference signal, and configure the sensing receiver to feed back time delay measurements and Doppler measurements. For example, the Doppler frequency measurement accuracy indication information can be the length of the time window used to measure the Doppler frequency.

[0447] The configuration of the sensing reference signal includes one or more of the following parameters:

[0448] P represents the number of sensing reference signal resources.

[0449] G represents the number of subsets of the sensing reference signal resources.

[0450] M is the number of sensing reference signal resources contained in each subset of sensing reference signal resources.

[0451] N is the number of time-domain symbols occupied by each sensing reference signal.

[0452] k is the time-domain OFDM symbol index of each sensing reference signal in each subset of sensing reference signals resources. For example, the OFDM symbol index can be represented as k = s + nΔ + m + gT.

[0453] s is the starting time-domain OFDM symbol index of the sensing reference signal in each sensing reference signal resource subset.

[0454] n = 0, ..., N-1 is the time-domain symbol index for each sensing reference signal.

[0455] Δ is the interval between two consecutive OFDM symbols occupied by each sensing reference signal in each subset of sensing reference signal resources.

[0456] m is the index of the sensing reference signal in each subset of sensing reference signal resources.

[0457] g = 0, ..., G are indices of the subset of sensing reference signal resources.

[0458] T represents the spacing between subsets of the sensing reference signal resources.

[0459] For example, when P=6, G=2, M=3, s=2, n=0,1, Δ=7, m=0,1,2, g=0,1,T=14, the time-domain OFDM symbol indices of the sensed reference signal in the first and second cycles are {2,3,4,9,10,11} and {16,17,18,23,24,25}, respectively, as shown in Figure 3.

[0460] Using the method of this disclosure, in step 2, a sensing reference signal in a subset can be configured to be mapped onto multiple OFDM symbols, resulting in a longer Doppler frequency measurement time window and improved Doppler measurement resolution. Simultaneously, by configuring adjacent OFDM symbols of the sensing reference signal to have a relatively small time interval, the maximum unambiguous range of the Doppler measurement can be increased. The sensing receiver performs high-precision Doppler estimation based on the time window, enhancing the accuracy and resolution of target detection. To reduce latency, the sensing node can configure a stronger sensing transmit beam, and / or sensing receive beam, and / or sensing transmit / receive beam pairs based on prior information, or delete invalid paths in the sensing auxiliary information.

[0461] Using the method of this embodiment, in step 2, the initial pairing of the sensing transmit and receive beam pairs can be achieved according to the configured sensing accuracy requirements, as well as the improvement of the sensing transmit and receive beam pairs. For example, the sensing transmit and receive beam pairs are both relatively thin beams, and then more sensing time-domain resources are configured to perform higher-precision Doppler estimation, thereby enhancing the accuracy of the selection of the sensing transmit and receive beam pairs and improving the sensing performance.

[0462] In the initial pairing or improvement of sensing transceiver beams, the sensing transmitter sends different sensing reference signals in the configured first time-frequency resources. The sensing receiver receives the sensing reference signals through the sensing receiving beam, measuring the Doppler frequency with time delay and limited accuracy. Thus, the sensing entity can determine the sensing target and the optimal sensing transceiver beam pair through distance and velocity sensing.

[0463] The sensing transmitter can be a network or a terminal, and the sensing receiver can also be a network or a terminal.

[0464] The first time-domain resource in the first time-frequency resource corresponds to the introduced Doppler measurement window, which is the time-domain resource span of each sensing reference signal.

[0465] The first time-frequency resource can be configured through a network or sensing nodes, or predefined by a protocol.

[0466] This disclosure proposes a sensing beam scanning method that is adapted to the characteristics of a sensing system. It reduces beam scanning time and improves Doppler estimation accuracy while effectively estimating the sensing target.

[0467] This disclosure proposes a sensing beam scanning method adapted to the characteristics of a sensing system.
