[0029] The embodiments of the present disclosure propose a perception method, a perception transmitter, a perception receiver, a perception system, and a medium.

[0030] In a first aspect, an embodiment of the present disclosure proposes a perception method, comprising: sending a perception reference signal based on N bursts, where the perception reference signal is a reference signal used for perception, the burst represents a resource unit occupied by the perception reference signal in the time domain and / or frequency domain, and N is an integer greater than or equal to 2.

[0031] In the above embodiment, sending the perception reference signal based on N bursts is conducive to measuring the perception reference signals in different bursts. Combining the measurement results of the perception reference signals in different bursts can obtain accurate perception quantity estimation and realize wireless perception.

[0032] In combination with some embodiments of the first aspect, in some embodiments, the bandwidths occupied by the N bursts in the frequency domain are different, and / or the frequency domain intervals between the orthogonal frequency division multiplexing (OFDM) subcarriers occupied by the N bursts in the frequency domain are different.

[0033] In the above embodiment, since the N bursts occupy different bandwidths in the frequency domain, the bandwidth of the sensing reference signal within each burst is different. Therefore, by combining the measurement results of the sensing reference signals from different bursts, a high-precision sensing quantity estimation can be obtained. Since the frequency domain spacing between the OFDM subcarriers occupied by the N bursts is different, the frequency domain density of the sensing reference signal within each burst is different. Therefore, by combining the measurement results of the sensing reference signals from different bursts, the problems of frequency domain undersampling and ambiguity in the sensing quantity can be avoided. Taking the sensing type of velocity as an example, the velocity resolution of different bursts is inconsistent, and the interference and noise immunity of the measurement results of different bursts are inconsistent. For example, bursts with high velocity resolution have poor interference immunity, while bursts with low velocity resolution have strong interference immunity. Therefore, a more accurate velocity estimation can be obtained by combining the N bursts and the applicable scenarios of each burst through weighted or nonlinear methods. However, when the N bursts have the same attributes, such as bandwidth, combining the measurement results of the N bursts can only produce a measurement result that can overcome random errors, such as A / D quantization, and has low robustness.

[0034] In combination with some embodiments of the first aspect, in some embodiments, based on the time domain in which each burst is located, the bandwidth occupied by the burst that is later in time is greater than the bandwidth occupied by the burst that is earlier in time, and the frequency domain interval between the OFDM subcarriers occupied by the burst that is later in time is greater than the frequency domain interval between the OFDM subcarriers occupied by the burst that is earlier in time; or, based on the time domain in which each burst is located, the bandwidth occupied by the burst that is later in time is less than the bandwidth occupied by the burst that is earlier in time, and the frequency domain interval between the OFDM subcarriers occupied by the burst that is later in time is less than the frequency domain interval between the OFDM subcarriers occupied by the burst that is earlier in time; or, based on the time domain in which each burst is located, the bandwidth occupied by the burst that is later in time is greater than or less than the bandwidth occupied by the burst that is earlier in time, and the number of OFDM subcarriers occupied by the N bursts is the same; or, based on the time domain in which each burst is located, the frequency domain interval between the OFDM subcarriers occupied by the burst that is later in time is greater than or less than the frequency domain interval between the OFDM subcarriers occupied by the burst that is earlier in time, and the number of OFDM subcarriers occupied by the N bursts is the same.

[0035] In the above embodiment, the bandwidth occupied by the N bursts in the frequency domain and the frequency domain spacing between the occupied OFDM subcarriers exhibit the same progressive change. That is, the bandwidth and frequency domain density of the N bursts exhibit opposite progressive changes. By measuring the perception reference signal within each burst, a highly accurate and unique (unambiguous) estimate of the perception quantity can be obtained. This not only achieves higher perception accuracy, but also avoids the perception ambiguity caused by frequency domain undersampling.

[0036] In combination with some embodiments of the first aspect, in some embodiments, the patterns of OFDM symbols occupied by the N bursts in the time domain are the same.

[0037] In the above embodiment, since the N bursts have the same time domain pattern, the configuration of the N bursts can be simplified.

[0093] Wireless communication and wireless sensing share a high degree of similarity. Integrated Sensing and Communication (ISAC) can unite wireless communication and wireless sensing, fostering close collaboration between the two. This approach benefits both wireless communication and wireless sensing, improving both the effectiveness and reliability of wireless communication and the accuracy of wireless sensing. Furthermore, devices that support both wireless communication and wireless sensing can reduce network deployment costs.

[0094] Wireless sensing typically requires estimating the target's range, azimuth angle (such as horizontal and vertical angles), and velocity. Broadly speaking, sensing also includes wireless tracking and radio frequency identification of the target. To achieve high-precision sensing, a sensing transmitter typically transmits a dedicated reference signal for sensing, which, for ease of description, will be referred to as a sensing reference signal. Optionally, the sensing reference signal does not carry any information or data used for communication.

[0098] It should be noted that the number of cognitive transmitters and the number of cognitive receivers shown in Figures 1a and 1b are only examples and do not constitute a limitation on the embodiments of the present disclosure. In actual situations, there can be one or more cognitive transmitters and one or more cognitive receivers.

[0099] It can be understood that the perception system in the embodiment of the present disclosure can correspond to a variety of perception scenarios, for example, it can be used for perception between terminals, or for perception between terminals and network devices, or for perception between network devices and network devices, etc.

[0100] In some embodiments, the sensing transmitter may be located in a terminal or a network device.

[0101] In some embodiments, the perceptual receiver may be located in a terminal or a network device.

[0102] Optionally, the cognitive transmitter and the cognitive receiver may be located in a network device.

[0103] Optionally, the perceptual transmitter may be located in a network device, and the perceptual receiver may be located in a terminal.

[0104] Optionally, the perceptual transmitter may be located in a terminal, and the perceptual receiver may be located in a network device.

[0105] Optionally, the cognitive transmitter and the cognitive receiver may be located in the terminal.

[0106] In some embodiments, the terminal may include at least one of a mobile phone, a wearable device, an Internet of Things device, a car with communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0107] In some embodiments, the network device is, for example, an access network device, which may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0108] Based on the perception system shown in Figures 1a and 1b, taking the estimation of the distance of the perception target as an example, the perception receiver needs to accurately estimate the arrival time of the first echo path reflected by the perception target (single-station perception mode) or the first path scattered by the perception target (dual-station perception mode). In order to improve the estimation accuracy, the wireless perception system needs to have a higher time domain resolution, and the time domain resolution depends on the bandwidth. In other words, the perception reference signal needs to have a larger bandwidth, which is very necessary for high-precision distance perception. On the other hand, if the frequency domain density of the perception reference signal is too low, that is, the frequency domain spacing of adjacent subcarriers of the perception reference signal is too large, it will cause frequency domain undersampling, causing the perception receiver to observe multiple channel impulse responses (CIR) mirror images, resulting in timing ambiguity and large perception errors.

[0109] In related technologies, the simplest and most intuitive approach is to use a uniform comb pattern for the sensing reference signal in the frequency domain. For example, positioning reference signals used in positioning, one of the sensing applications, are evenly spaced in the frequency domain. Given this, sensing reference signals often also use a comb pattern that is evenly distributed in the frequency domain. To completely avoid timing ambiguity caused by frequency domain undersampling and achieve high time domain resolution, the sensing reference signal must meet both high frequency domain density and large bandwidth requirements.

[0110] However, if the perception reference signal meets both the conditions of high frequency domain density and large bandwidth, it will bring two problems: First, the perception reference signal overhead is too large, occupying too many frequency domain resources, resulting in low frequency utilization of the synaesthesia system.

[0111] Second, when the total transmit power of the sensing transmitter is constant (which is often the case in practice), especially when the terminal acts as the sensing transmitter, the high frequency density and wide bandwidth of the sensing reference signal will result in too low power per sensing reference signal resource element (RE), that is, too low EPRE (energy per resource element). This will inevitably reduce sensing accuracy and performance.

[0112] Figure 2a is a flow chart of a sensing method according to an embodiment of the present disclosure. As shown in Figure 2a, the embodiment of the present disclosure relates to a sensing transmitter in the sensing system shown in Figure 1a. Optionally, in single-station mode, the sensing transmitter may also be referred to as a sensing receiver. The sensing method includes:

[0113] Step S2101: The sensing transmitter obtains configuration information and determines N bursts based on the configuration information.

[0114] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0115] In some embodiments, N is an integer greater than or equal to 2, that is, two or more bursts are determined in the above steps.

[0116] In some embodiments, a burst may represent resource units occupied by a sensing reference signal in the time domain and / or frequency domain. For example, a burst may represent OFDM symbols occupied by a sensing reference signal in the time domain and OFDM subcarriers occupied in the frequency domain.

[0117] In some embodiments, a burst may represent a two-dimensional pattern of a sensing reference signal on a time-frequency resource grid, that is, a set of resource elements where the sensing reference signal is located.

[0118] In some embodiments, the resource units occupied by a burst in the time domain may be indicated by a first set, for example, the first set includes the OFDM symbol numbers occupied by the burst. Optionally, the first set may also be referred to as a symbol number set.

[0119] In some embodiments, the resource units occupied by the burst in the frequency domain may be indicated by a second set, for example, the second set includes the OFDM subcarrier numbers occupied by the burst. Optionally, the second set may also be referred to as a subcarrier number set.

[0120] In the above embodiment, the set of resource elements where the sensing reference signal is located in each burst can be obtained through the OFDM symbol numbers in the first set and / or the OFDM subcarrier numbers in the second set.

[0121] For the convenience of description, assume that the nth burst occupies L in the time domain. n OFDM symbols, and occupy K in the frequency domain n OFDM subcarriers, the first set is expressed as The second set is represented as Where n=1,…,N.

[0122] In the first set above, each element in the set can represent an OFDM symbol number, such as Indicates that the nth burst occupies the Lth n The number of OFDM symbols.

[0123] In the above second set, each element in the set can represent an OFDM subcarrier number, such as Indicates that the nth burst occupies the Kth n The number of the OFDM subcarriers.

[0124] In some embodiments, different bursts may have the same time domain pattern, for example, the pattern of OFDM symbols occupied by N bursts in the time domain may be the same.

[0125] For example, for any two bursts n1 and n2 (n1≠n2), the total number of OFDM symbols occupied by burst n1 and burst n2 in the time domain is the same, that is, holds, and for any The symbol interval between the i-th OFDM symbol and the j-th OFDM symbol occupied by burst n1 is the same as the symbol interval between the i-th OFDM symbol and the j-th OFDM symbol occupied by burst n2, that is, Established.

[0126] In the above embodiment, since the N bursts have the same time domain pattern, the configuration of the N bursts can be simplified.

[0127] In some embodiments, the patterns of OFDM symbols occupied by the N bursts in the time domain may be different.

[0128] In some embodiments, the number of OFDM subcarriers occupied by the N bursts in the frequency domain may be the same.

[0129] For example, for any two bursts n1 and n2 (n1≠n2), the total number of OFDM subcarriers occupied by burst n1 and burst n2 in the frequency domain is the same, that is, Established.

[0130] In the above embodiment, since the N bursts occupy the same number of OFDM subcarriers, the configuration of the N bursts can be simplified, and the bandwidth of the N bursts and / or the frequency domain spacing between OFDM subcarriers can be easily controlled.

[0131] In some embodiments, the number of OFDM subcarriers occupied by the N bursts in the frequency domain may be different.

[0132] In some embodiments, the bandwidth occupied by N bursts in the frequency domain may be different. It should be noted that the bandwidth occupied by each burst can be defined as the bandwidth from the starting OFDM subcarrier to the ending OFDM subcarrier occupied by the burst. For example, assuming B n represents the bandwidth occupied by the nth burst, then for any p,q=1,2,…,K n ,p≠q, there is

[0133] Among them, |kn,p -k n,q | represents the bandwidth between the pth OFDM subcarrier and the qth OFDM subcarrier occupied by the nth burst.

[0134] In the above embodiment, since the N bursts occupy different bandwidths in the frequency domain, the bandwidth of the perception reference signal in each burst is different. Therefore, by combining the measurement results of the perception reference signals in different bursts, a high-precision perception quantity estimation can be obtained.

[0135] Optionally, the bandwidth occupied by the N bursts in the frequency domain may become wider and wider, that is, for any two bursts, based on the time domain where each burst is located, the bandwidth occupied by the burst later in time is greater than the bandwidth occupied by the burst earlier in time.

[0136] For example, for any two bursts n1 and n2 (n1≠n2), based on the time domain where burst n1 is located and the time domain where burst n2 is located, it can be seen that burst n2 is later in time, so the bandwidth occupied by burst n2 is greater than the bandwidth occupied by burst n1, that is, Established.

[0137] Optionally, the bandwidth occupied by the N bursts in the frequency domain may become narrower and narrower, that is, for any two bursts, based on the time domain where each burst is located, the bandwidth occupied by the burst later in time is smaller than the bandwidth occupied by the burst earlier in time.

[0138] In the above embodiment, the bandwidth occupied by the N bursts in the frequency domain changes gradually, for example, the bandwidth increases successively, which is conducive to gradually improving the perception accuracy of the perception amount or gradually narrowing the estimation range of the perception amount when measuring the perception reference signal in each burst.

[0139] In some embodiments, the frequency domain intervals between OFDM subcarriers occupied by the N bursts in the frequency domain are different.

[0140] It can be understood that the frequency domain spacing between OFDM subcarriers occupied by a burst in the frequency domain is associated with the frequency domain density of the burst. Optionally, the frequency domain density can indicate the number of OFDM subcarriers occupied within a PRB. For example, a burst frequency domain density of p = 3 indicates that the burst occupies 3 subcarriers within each PRB. For another example, a burst frequency domain density of p = 1 / 2 indicates that the burst occupies 1 subcarrier within every two PRBs.

[0141] It can be understood that the frequency domain spacing between OFDM subcarriers occupied by a burst in the frequency domain is inversely proportional to the frequency domain density of the burst. The larger the frequency domain spacing between OFDM subcarriers occupied by a burst in the frequency domain, the smaller the frequency domain density of the burst; conversely, the smaller the frequency domain spacing, the greater the frequency domain density.

[0142] In the above embodiment, the frequency domain intervals between the OFDM subcarriers occupied by N bursts in the frequency domain are different, that is, the frequency domain density of the perception reference signal in each burst is different. Therefore, by combining the measurement results of the perception reference signals in different bursts, the problems of frequency domain undersampling and perception ambiguity can be avoided.

[0143] Optionally, the frequency domain interval between the OFDM subcarriers occupied by N bursts in the frequency domain can become larger and larger, that is, for any two bursts, based on the time domain in which each burst is located, the frequency domain interval between the OFDM subcarriers occupied by the burst that is later in time is greater than the frequency domain interval between the OFDM subcarriers occupied by the burst that is earlier in time.

[0144] Based on this, the frequency domain density of the N bursts becomes smaller and smaller, that is, the frequency domain density of the burst later in time is smaller than the frequency domain density of the burst earlier in time.

[0145] Optionally, the frequency domain interval between the OFDM subcarriers occupied by N bursts in the frequency domain can become smaller and smaller, that is, for any two bursts, based on the time domain in which each burst is located, the frequency domain interval between the OFDM subcarriers occupied by the burst that is later in time is smaller than the frequency domain interval between the OFDM subcarriers occupied by the burst that is earlier in time.

[0146] Based on this, the frequency domain density of the N bursts becomes larger and larger, that is, the frequency domain density of the bursts later in time is greater than the frequency domain density of the bursts earlier in time.

[0147] In the above embodiment, the frequency domain interval between the OFDM subcarriers occupied by N bursts in the frequency domain changes gradually, that is, the frequency domain density of the N bursts changes gradually, which is conducive to gradually improving the perception accuracy of the perception amount or gradually narrowing the estimation range of the perception amount when measuring the perception reference signal in each burst.

[0148] In some embodiments, for the bandwidth occupied by N bursts in the frequency domain and the frequency domain spacing between OFDM subcarriers, any one of the following situations can be satisfied: Situation (1): Based on the time domain in which each burst is located, the bandwidth occupied by the burst later in time is greater than the bandwidth occupied by the burst earlier in time, and the frequency domain spacing between the OFDM subcarriers occupied by the burst later in time is greater than the frequency domain spacing between the OFDM subcarriers occupied by the burst earlier in time.

[0149] In case (1), the bandwidth occupied by the N bursts increases successively, and the frequency domain interval between the OFDM subcarriers occupied by the N bursts also increases successively, that is, the frequency domain density of the N bursts decreases successively.

[0150] Case (2): Based on the time domain where each burst is located, the bandwidth occupied by the burst later in time is smaller than the bandwidth occupied by the burst earlier in time, and the frequency domain interval between the OFDM subcarriers occupied by the burst later in time is smaller than the frequency domain interval between the OFDM subcarriers occupied by the burst earlier in time.

[0151] In case (2), the bandwidth occupied by the N bursts decreases successively, and the frequency domain interval between the OFDM subcarriers occupied by the N bursts also decreases successively, that is, the frequency domain density of the N bursts increases successively.

[0152] Case (3): Based on the time domain where each burst is located, the bandwidth occupied by the burst later in time is greater or smaller than the bandwidth occupied by the burst earlier in time, and the number of OFDM subcarriers occupied by the N bursts is the same.

[0153] In case (3), in some examples, the bandwidth occupied by N bursts increases successively. Since the number of OFDM subcarriers occupied by the N bursts is the same, the frequency domain interval between the OFDM subcarriers occupied by the N bursts also increases successively, that is, the frequency domain density of the N bursts decreases successively; or, in some examples, the bandwidth occupied by N bursts decreases successively. Since the number of OFDM subcarriers occupied by the N bursts is the same, the frequency domain interval between the OFDM subcarriers occupied by the N bursts also decreases successively, that is, the frequency domain density of the N bursts increases successively.

[0154] Case (4): Based on the time domain where each burst is located, the frequency domain interval between the OFDM subcarriers occupied by the burst later in time is greater or smaller than the frequency domain interval between the OFDM subcarriers occupied by the burst earlier in time, and the number of OFDM subcarriers occupied by N bursts is the same.

[0155] In case (4), in some examples, the frequency domain interval between the OFDM subcarriers occupied by N bursts increases successively, that is, the frequency domain density of the N bursts decreases successively, and since the number of OFDM subcarriers occupied by the N bursts is the same, the bandwidth occupied by the N bursts increases successively; or, in some examples, the frequency domain interval between the OFDM subcarriers occupied by N bursts decreases successively, that is, the frequency domain density of the N bursts increases successively, and since the number of OFDM subcarriers occupied by the N bursts is the same, the bandwidth occupied by the N bursts decreases successively.

[0156] Among them, in the above case (3), the number of OFDM subcarriers occupied by N bursts implicitly indicates the frequency domain spacing between the OFDM subcarriers occupied by N bursts or the frequency domain density of N bursts. In the above case (4), the number of OFDM subcarriers occupied by N bursts implicitly indicates the bandwidth occupied by N bursts.

[0157] Based on the above-mentioned scenarios, taking two bursts as an example, in one embodiment, the first burst has a high frequency domain density and a small bandwidth, and the second burst has a low frequency domain density and a large bandwidth. In another embodiment, the first burst has a low frequency domain density and a large bandwidth, and the second burst has a high frequency domain density and a small bandwidth.

[0158] FIG3 is a schematic diagram of a time-frequency resource grid including two bursts according to an embodiment of the present disclosure. Referring to the time-frequency resource grid shown in FIG3 , the first burst has a high frequency domain density but a small bandwidth, which indicates that the first set of OFDM symbol numbers is The second set of OFDM subcarrier numbers is indicated as The second burst has a low frequency domain density but a larger bandwidth, which indicates that the first set of OFDM symbol numbers is It indicates that the second set of OFDM subcarrier numbers is

[0159] In some embodiments, the sensing transmitter determines N bursts based on the acquired configuration information.

[0160] Optionally, the above configuration information may include at least one of the following: the number of bursts N; the first set corresponding to at least one burst; the second set corresponding to at least one burst; the parameters corresponding to at least one burst for determining the first set; and the parameters corresponding to at least one burst for determining the second set.

[0161] In the above embodiment, the first set corresponding to at least one of the N bursts can be directly configured, or the first set can be indirectly configured by configuring the parameters corresponding to at least one of the N bursts used to determine the first set, thereby reducing the information required for configuration. Similarly, the second set corresponding to at least one of the N bursts can be directly configured, or the second set can be indirectly configured by configuring the parameters corresponding to at least one of the N bursts used to determine the second set, thereby reducing the information required for configuration.

[0175] In some examples, taking the configuration information including parameters (b), (e), and (f) as an example:

[0176] According to the above optional implementation, the pattern of OFDM symbols occupied by N bursts can be the same. Based on this, different bursts have different starting time slot numbers, but have the same set of OFDM symbol numbers within the time slot. Therefore, the configuration information of N bursts may include: the starting time slot numbers of N bursts: s = {s1, s2, ..., s N}; The set of OFDM symbol numbers of the burst in the starting time slot (the set of OFDM symbol numbers in the time slot): l′={l′1,l′2,…,l′ L}; The total number of OFDM symbols occupied by the burst: L.

[0177] In some embodiments, for a burst uniformly distributed in the frequency domain, such as burst n, its corresponding parameters for determining the second set may be configured in the above configuration information, thereby indirectly configuring the second set.

[0178] Optionally, the parameters used to determine the second set may include at least one of the following: (g) the starting OFDM subcarrier number k of the burst n,1 ; (h) burst starting PRB number p n (i) The starting OFDM subcarrier number k' of the burst within the starting PRB n,1 (j) Total number of OFDM subcarriers occupied by the burst K n (k) Frequency domain spacing between OFDM subcarriers occupied by bursts (l) The frequency domain density of the burst ρ.

[0186] in, is the number of OFDM subcarriers contained in a PRB.

[0187] In the above embodiment, the second set can be determined by configuring at least one parameter among parameters (g) to (l).

[0192] In some examples, taking the configuration information including parameters (g), (j), and (k / l) as an example:

[0193] Generally, the configuration information of N bursts may include: the total number of OFDM subcarriers occupied by N bursts: K = {K1, K2, ..., K n}.

[0195] Generally, the configuration information of N bursts may include: frequency domain density of N bursts: ρ = {ρ1, ρ2, ..., ρ N}; or, the frequency domain spacing between the OFDM subcarriers occupied by N bursts:

[0196] Generally, the configuration information of N bursts may include: the starting OFDM subcarrier numbers of N bursts: k1={k 1,1 ,k 2,1 ,…,k N,1}.

[0197] Optionally, when the starting OFDM subcarrier numbers of N bursts are the same, the above starting OFDM subcarrier number list becomes one number.

[0198] In some examples, the configuration information includes parameters (h), (i), (j), and (k / l) as an example: In general, the configuration information of N bursts may include: the total number of OFDM subcarriers occupied by N bursts: K = {K1, K2, ..., K N}.

[0200] Generally, the configuration information of N bursts may include: frequency domain density of N bursts: ρ = {ρ1, ρ2, ..., ρ N}; or, the frequency domain spacing between the OFDM subcarriers occupied by N bursts:

[0201] Generally, the configuration information of N bursts may include: the starting PRB numbers of the N bursts: p = {p1, p2, ..., p N}.

[0202] Optionally, when the starting PRB numbers of N bursts are the same, the above starting PRB number list becomes one number.

[0207] In some embodiments, the cognitive transmitter may obtain the configuration information from the core network. Alternatively, the cognitive transmitter may receive the configuration information sent by a core network element.

[0208] In some embodiments, the core network element may be an LMF (location management functionality) network element, or a network element specifically used for sensing, such as an SMF (sensing management functionality) network element.

[0209] In some embodiments, the perceptual transmitter may obtain the above configuration information from a perceptual application.

[0210] It should be noted that the embodiments of the present disclosure do not limit the specific implementation method of the sensing transmitter obtaining the above configuration information.

[0211] In some embodiments, the sensing transmitter may determine the first set and the second set corresponding to each burst according to the above configuration information, thereby determining N bursts.

[0212] Step S2102: The sensing transmitter sends a sensing reference signal based on N bursts.

[0213] In some embodiments, the sensing transmitter sends a sensing reference signal based on resource elements represented by N bursts.

[0214] In some embodiments, the entire set of sensing reference signals within the N bursts may be referred to as a sensing reference signal series.

[0215] In some embodiments, terms such as burst, occasion, and pattern may be used interchangeably.

[0216] In some embodiments, the N bursts as a whole may be referred to as an opportunity or a pattern.

[0217] In some embodiments, each burst may be referred to as a sub-opportunity or a sub-pattern, respectively.

[0218] In some embodiments, each burst may be referred to as an opportunity or a pattern, respectively.

[0219] Step S2103: The sensing transmitter receives a sensing reference signal.

[0220] Step S2104: The sensing transmitter measures the sensing reference signal.

[0221] In some embodiments, the sensing transmitter obtains configuration information, determines N bursts based on the configuration information, sends a sensing reference signal based on the N bursts, receives the sensing reference signal, and measures the sensing reference signal.

[0222] In the above embodiment, the sensing transmitter combines the measurement results of the sensing reference signals in different bursts to obtain accurate estimation of the sensing quantity and realize wireless sensing.

[0223] Optionally, according to the above optional implementation, the bandwidth occupied by the N bursts in the frequency domain and the frequency domain spacing between the occupied OFDM subcarriers can show the same progressive change, that is, the bandwidth and frequency domain density of the N bursts can show opposite progressive changes, for example, the bandwidth increases successively and the frequency domain density decreases successively. Referring to the time-frequency resource grid shown in Figure 3, taking the perception distance as an example, for a burst with a high frequency domain density but a small bandwidth, such as the first burst in Figure 3, the perception transmitter measures the perception reference signal in the first burst and can obtain a rough (lower precision) estimate of the perception quantity. Since the frequency domain density of the perception reference signal in the burst is high, the problem of frequency domain undersampling and perception quantity ambiguity is avoided.

[0224] For a burst with low frequency domain density but large bandwidth, such as the second burst in Figure 3, the sensing transmitter measures the sensing reference signal within the second burst and can obtain one or more high-precision estimates of the sensing quantity. Since the sensing reference signal bandwidth within this burst is large, the time domain resolution and sensing accuracy are high. However, due to the low frequency domain density of the sensing reference signal within this burst, frequency domain undersampling may occur, resulting in multiple estimates of the sensing quantity, which in turn leads to the problem of ambiguity in the sensing quantity.

[0225] Therefore, since the N bursts show opposite progressive changes in occupied bandwidth and frequency domain density, based on measuring the perception reference signals within the N bursts and combining the measurement results of the perception reference signals in different bursts, the perception transmitter can obtain a high-precision and unique (unambiguous) estimate of the perception quantity.

[0226] In the above embodiment, the sensing process may be completed through a series of progressive iterations, such as the sensing transmitter sequentially measuring the sensing reference signal in each burst, thereby gradually improving the sensing accuracy of the sensing quantity or gradually narrowing the estimation range of the sensing quantity.

[0234] FIG2b is a flow chart of a perception method according to an embodiment of the present disclosure. As shown in FIG2b , the embodiment of the present disclosure relates to a perception transmitter and a perception receiver in the perception system shown in FIG2b . The perception method includes:

[0235] Step S2201: The sensing transmitter obtains configuration information and determines N bursts based on the configuration information.

[0236] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0237] Step S2202: The sensing transmitter sends a sensing reference signal based on N bursts.

[0238] The optional implementation of step S2202 can refer to the optional implementation of step S2102 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0239] Step S2203: The perception receiver obtains configuration information and determines N bursts based on the configuration information.

[0240] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0241] In some embodiments, the perceptual transmitter may send the configuration information to the perceptual receiver, and the perceptual receiver receives the configuration information and determines N bursts based on the configuration information.

[0242] In some embodiments, the perceptual receiver may obtain the configuration information from the core network. Alternatively, the perceptual receiver may receive the configuration information sent by a core network element and determine the N bursts based on the configuration information.

[0243] In some embodiments, the core network element may be an LMF network element, or a network element specifically used for perception, such as an SMF network element.

[0244] It should be noted that the embodiments of the present disclosure do not limit the specific implementation method of the perception receiver obtaining the above configuration information.

[0245] In some embodiments, the perceptual receiver may determine the first set and the second set corresponding to each burst based on the above configuration information, thereby determining N bursts.

[0246] In some embodiments, the optional implementation manner in which the perceptual receiver determines N bursts based on the configuration information is the same as the optional implementation manner in which the perceptual transmitter determines N bursts based on the configuration information.

[0247] Therefore, for the optional implementation of step S2203, reference may be made to the optional implementation of step S2101 in FIG2a and other related parts in the embodiment involved in FIG2a, which will not be described in detail here.

[0248] In some embodiments, step S2203 and step S2202 may be executed in an exchanged order or simultaneously, and step S2203 and step S2201 may be executed in an exchanged order or simultaneously.

[0249] Step S2204: The perception receiver receives a perception reference signal based on the N bursts.

[0250] In some embodiments, the sensing receiver receives a sensing reference signal based on resource elements represented by N bursts.

[0251] In step S2205 , the sensing receiver measures the sensing reference signal.

[0252] In some embodiments, the perceptual transmitter and the perceptual receiver obtain configuration information and determine N bursts based on the configuration information. The perceptual transmitter sends a perceptual reference signal based on the N bursts. The perceptual receiver receives the perceptual reference signal based on the N bursts and measures the perceptual reference signal.

[0253] In the above embodiment, the sensing receiver combines the measurement results of the sensing reference signals in different bursts to obtain accurate estimation of the sensing quantity and realize wireless sensing.

[0254] Optionally, according to an optional implementation, the bandwidth occupied by the N bursts in the frequency domain and the frequency domain spacing between the occupied OFDM subcarriers can show the same progressive change, that is, the bandwidth and frequency domain density of the N bursts can show opposite progressive changes, for example, the bandwidth increases successively and the frequency domain density decreases successively. Referring to the time-frequency resource grid shown in Figure 3, taking the perception distance as an example, for a burst with a high frequency domain density but a small bandwidth, such as the first burst in Figure 3, the perception receiver measures the perception reference signal in the first burst and can obtain a rough (lower precision) estimate of the perception quantity. Since the frequency domain density of the perception reference signal in the burst is high, the problem of frequency domain undersampling and perception quantity ambiguity is avoided.

[0255] For a burst with low frequency domain density but large bandwidth, such as the second burst in Figure 3, the sensing receiver measures the sensing reference signal within the second burst and can obtain one or more high-precision estimates of the sensing quantity. Since the sensing reference signal bandwidth within this burst is large, the time domain resolution and sensing accuracy are high. However, due to the low frequency domain density of the sensing reference signal within this burst, frequency domain undersampling may occur, resulting in multiple estimates of the sensing quantity, which in turn leads to the problem of ambiguity in the sensing quantity.

[0256] Therefore, since the N bursts show opposite progressive changes in occupied bandwidth and frequency domain density, based on measuring the perception reference signals within the N bursts and combining the measurement results of the perception reference signals in different bursts, the perception receiver can obtain a high-precision and unique (unambiguous) estimate of the perception quantity.

[0257] In the above embodiment, the sensing process may be completed through a series of progressive iterations, such as the sensing receiver sequentially measuring the sensing reference signal in each burst, thereby gradually improving the sensing accuracy of the sensing quantity or gradually narrowing the estimation range of the sensing quantity.

[0258] Compared with the perception reference signal solution with high frequency domain density and small bandwidth, the embodiment of the present disclosure can achieve higher perception accuracy.

[0259] Compared with the perception reference signal solution with low frequency domain density and large bandwidth, the embodiment of the present disclosure can completely avoid the perception ambiguity problem caused by frequency domain undersampling.

[0260] Compared to high-density and wide-bandwidth sensing reference signal solutions in the frequency domain, the disclosed embodiments can achieve comparable sensing performance, including sensing accuracy and range. Furthermore, the disclosed embodiments have lower resource overhead and higher EPRE, which is particularly important for power-constrained devices (e.g., terminals).

[0261] The perception method involved in the embodiments of the present disclosure may include at least one of the above steps S2201 to S2205. For example, step S2201 can be implemented as an independent embodiment, step S2202 can be implemented as an independent embodiment, step S2201 + step S2202 can be implemented as an independent embodiment, step S2203 can be implemented as an independent embodiment, step S2204 can be implemented as an independent embodiment, step S2202 + step S2204 can be implemented as an independent embodiment, steps S2203 + S2204 can be implemented as an independent embodiment, and steps S2204 + S2205 can be implemented as an independent embodiment, but are not limited thereto.
