[0004] In New Radio (NR) systems, targets can be detected and estimated based on sensing signals. This allows for determination of target presence and estimation of speed, distance, and incoming wave direction.

[0062] To facilitate a better understanding of the embodiments of the present application, communication perception integration / synaesthesia integration is explained.

[0063] 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, supporting 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, XR, and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0064] JSAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0065] Currently, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1 below.

[0066] Table 1 Typical scenarios of communication perception integration

[0067] There are six basic sensing modes, depending on the difference between the sending and receiving nodes of the sensing signal, as shown in Figure 2:

[0068] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0069] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0070] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0071] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0072] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0073] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurements.

[0074] It's worth noting that each sensing method in Figure 2 uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. In actual scenarios, the range of sensing targets will be much richer.

[0075] To facilitate a better understanding of the embodiments of the present application, a basic method of perceptual signal design is described.

[0076] This paper examines the resource allocation requirements for sensing signals under given sensing requirements.

[0077] Perception requirements include requirements for the resolution and / or maximum unambiguous measurement range of target parameters, including delay or distance, Doppler or velocity, and angle.

[0078] Resources are resources on the target domain corresponding to the target parameters. The target domain and resources on the target domain include:

[0079] Time domain: time resources, including orthogonal frequency-division multiplexing (OFDM) symbols, time slots, subframes, frames, etc.

[0080] Frequency domain: frequency resources, including subcarriers, resource blocks (RBs), etc.

[0081] Airspace: antenna or port resources.

[0082] The requirements for resource allocation based on perceived demand mainly include two aspects:

[0083] Resource span: In the target domain, the span of resources in a perception frame from the minimum resource unit index to the maximum resource unit index, including: time length (time domain), bandwidth (frequency domain), and aperture (spatial dimension);

[0084] Resource unit spacing: In the target dimension, the spacing between adjacent resource units in the target domain within a perception frame, including: the spacing between OFDM symbols allocated to perception signals (time domain), the spacing between subcarriers allocated to perception signals (frequency domain), and the spacing between antennas or ports allocated to perception signals (spatial domain).

[0085] The impact of resource allocation on perception includes:

[0086] The span of the resource determines the resolution of the target parameter, including: the time span in the time domain determines the measurement resolution of Doppler or velocity, the bandwidth in the frequency domain determines the measurement resolution of delay or distance, and the aperture in the spatial domain determines the measurement resolution of angle.

[0087] The resource unit spacing determines the maximum unambiguous measurement range of the target parameter, including: the spacing between OFDM symbols allocated to the sensing signal in the time domain determines the maximum unambiguous measurement range of Doppler or velocity; the spacing between subcarriers allocated to the sensing signal in the frequency domain determines the maximum unambiguous measurement range of delay or distance; and the spacing between antennas or ports allocated to the sensing signal in the spatial domain determines the maximum unambiguous measurement range of angle.

[0088] The following discussion focuses on the resource configuration of time domain and frequency domain to discuss the relationship between the resource configuration of perception signals and perception requirements.

[0089] Latency / Distance: When sensing through electromagnetic waves, the direct information obtained is latency, and distance is calculated from latency. Therefore, this article focuses on the relationship between latency and the resource allocation of perception signals.

[0090] The resolution of the delay is given by:

[0091] Where B represents the signal bandwidth.

[0092] The maximum unambiguous measurement range of the delay is given by:

[0093] Wherein, Δf is the interval between adjacent subcarriers allocated to the perception signal.

[0094] Doppler / speed: When sensing through electromagnetic waves, Doppler information is directly obtained, and speed is converted from Doppler. Therefore, the main discussion here is the relationship between Doppler and the resource allocation of perception signals.

[0095] The Doppler resolution is given by:

[0096] Where T is the time length of a perception frame.

[0097] The maximum unambiguous measurement range of Doppler is given by:

[0098] Where Δt represents the interval between adjacent OFDM symbols allocated to the sensing signal.

[0099] According to the above analysis, when the delay and Doppler resolution and the maximum unambiguous measurement range in the given perception requirements are given, that is, given Δτ, τ max , Δf d and f d,max Afterwards, the number of required sensing resources includes the number of subcarriers and the number of OFDM symbols.

[0100] Among them, the number of subcarriers is as follows: The number of OFDM symbols is

[0101] The following uses a typical scenario to illustrate the requirements of sensing signals for sensing resources (subcarriers and OFDM symbols). Considering the traffic monitoring scenario, the specific sensing resources required can be described as follows:

[0102] The maximum unambiguous ranging range is 200m;

[0103] The ranging resolution is 0.2m;

[0104] The speed measurement range is -180km / h to 180km / h (capable of detecting speeding vehicles, both approaching and moving away);

[0105] The speed measurement resolution is 0.2m / s (capable of distinguishing slowly walking pedestrians).

[0106] Considering the millimeter wave band with a carrier center frequency of 30 GHz, the corresponding sensing resource configuration must meet the following conditions:

[0107] Bandwidth B ≥ 750 MHz;

[0108] The spacing Δf between adjacent subcarriers allocated to the perception signal is ≤ 1500 kHz;

[0109] The time length of the perception frame T≥25ms;

[0110] The interval Δt between adjacent OFDM symbols allocated to the sensing signal is ≤ 50 μs.

[0111] Based on the above analysis, the number of sensing resources required in the traffic monitoring scenario given here is:

[0112] The number of subcarriers N scs ≥500;

[0113] The number of OFDM symbols N symbol ≥500.

[0114] It can be seen that in order to meet the perception requirements of the above-mentioned traffic monitoring scenarios, the overhead of time domain and frequency domain resources is relatively large. Further consider the proportion of the above-mentioned time-frequency domain resource overhead in the entire time-frequency domain. In the case of a 30GHz center frequency, considering that the subcarrier spacing is 120kHz, the time length of the OFDM symbol is 8.33μs. In order to meet the above-mentioned resource configuration requirements, one subcarrier in every 12 subcarriers must be allocated to the perception signal, and one OFDM symbol in every six OFDM symbols must be allocated to the perception signal. In the scenario of multi-port perception, the proportion of perception resource overhead will be further increased.

[0115] An embodiment of the present application provides a perception resource configuration scheme. By staggering the time-frequency resources of the perception signal, it is possible to have two maximum unambiguous measurement areas (delay-Doppler domain areas) while keeping the number of occupied resource elements (REs) unchanged, thereby enabling measurement of perception targets with more different motion characteristics.

[0116] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0170] It should be understood that the index value described in the embodiment of the present application may be an index value in a communication system.

[0171] In some embodiments, the perception signal corresponding to the first time-frequency resource set has at least one of the following measurement ranges:

[0172] a first specific measurement range, a second specific measurement range;

[0173] If the speed of the perceived target is unknown, the first specific measurement range includes: a delay range of 0 to τ max,1 , Doppler range -υ max,1 / 2 to υ max,1 / 2; If the speed of the perceived target is known, the first specific measurement range includes: delay range 0 to τ max,1 , Doppler range 0 to υ max,1 or 0 to -υ max,1 ;

[0174] If the speed of the perceived target is unknown, the second specific measurement range includes: a delay range of 0 to τ max,2 , Doppler range -υ max,2 / 2 to υ max,2 / 2; If the speed of the perceived target is known, the second specific measurement range includes: delay range 0 to τ max,2 , Doppler range 0 to υ max,2 or 0 to -υ max,2 ;

[0175] Among them, τ max,1 =1 / (Δ2Δf),υ max,1 =1 / (ΔpΔT), τ max,2 =1 / (ΔqΔf),v max,2 =1 / (Δ1ΔT), ΔT represents the target time domain unit duration, Δf represents the target frequency domain unit interval, Δp=DΔ1, Δq=DΔ2, Δ1 represents the number of time domain units between two adjacent target time domain units, Δ2 represents the number of frequency domain units between two adjacent target frequency domain units, and Δ1, Δ2, ΔT, Δf and D are all positive integers.

[0176] For example, if the speed of the perceived target is known, the first specific measurement range includes: a time delay range of 0 to τ max,1 , Doppler range 0 to υ max,1 .

[0177] For another example, if the speed of the perceived target is known, the first specific measurement range includes: a delay range of 0 to τ max,1 , Doppler range 0 to -υ max,1 .

[0178] For example, if the speed of the perceived target is known, the second specific measurement range includes: a time delay range of 0 to τ max,2 , Doppler range 0 to υ max,2 .

[0179] For another example, if the speed of the perceived target is known, the second specific measurement range includes: a delay range of 0 to τ max,2 , Doppler range 0 to -υ max,2 .

[0180] It should be noted that the specific measurement range described in the embodiments of the present application can also be referred to as an unambiguous measurement range, which can be replaced with each other, and the present application is not limited to this.

[0181] Illustratively, the first specific measurement range may be as shown in FIG. 5 , and the second specific measurement range may be as shown in FIG. 6 .

[0182] Specifically, the first specific measurement range shown in Figure 5 can be the measurement range of the perception signal corresponding to the perception resource set shown in Figure 7 (also referred to as the unambiguous measurement range), and the second specific measurement range shown in Figure 6 can be the measurement range of the perception signal corresponding to the perception resource set shown in Figure 8 (also referred to as the unambiguous measurement range).

[0183] Optionally, the sensing resource set shown in FIG7 may include the following features:

[0184] As shown in FIG7 , the REs in the sensing resource set are distributed over P time domain units in the time domain and over N frequency domain units in the frequency domain;

[0185] In the sensing resource set shown in FIG7 , the interval between any two adjacent time domain units is Δp time domain unit durations, and the interval between any two adjacent frequency domain units is Δ2 frequency domain unit intervals.

[0186] Specifically, if P=M / D and Δp=DΔ1, the sensing signal corresponding to the sensing resource set shown in Figure 7 has the above-mentioned first specific measurement range. The number of REs in the sensing resource set shown in Figure 7 is also MN / D, the same as the first time-frequency resource set.

[0187] Optionally, the sensing resource set shown in FIG8 may include the following features:

[0188] As shown in FIG8 , the REs in the sensing resource set are distributed over M time domain units in the time domain and over Q frequency domain units in the frequency domain.

[0189] In the sensing resource set shown in FIG8 , any two adjacent time domain units are spaced apart by a time domain unit duration of Δ1, and any two adjacent subcarriers are spaced apart by a frequency domain unit duration of Δq.

[0190] Specifically, if Q=N / D and Δq=DΔ2, the sensing signal corresponding to the sensing resource set shown in Figure 8 has the above-mentioned second specific measurement range. The number of REs in the sensing resource set shown in Figure 8 is also MN / D, which is the same as the first time-frequency resource set.

[0191] Specifically, the number of REs in the sensing resource set shown in FIG7 and the sensing resource set shown in FIG8 is also MN / D, which is the same as that in the first time-frequency resource set. The sensing signal corresponding to the first time-frequency resource set also has the same (or approximately the same) delay resolution and Doppler resolution as the sensing signal corresponding to the sensing resource set shown in FIG7 and the sensing resource set shown in FIG8.

[0192] Therefore, in this embodiment, under the premise of occupying the same number of REs, and under the premise of the same (or approximately the same) delay resolution and Doppler resolution, the first time-frequency resource set has two maximum unambiguous measurement ranges of the perception resource set shown in Figure 7 and the perception resource set shown in Figure 8, thereby being applicable to the measurement of perception targets in more situations.

[0209] Parameter D;

[0210] An index value l0 of a starting target time domain unit of the first time-frequency resource set in the time domain;

[0211] An index value k0 of a starting target frequency domain unit of the first time-frequency resource set in the frequency domain;

[0212] Wherein, Δ1, Δ2, M, N and D are all positive integers.

[0213] In this embodiment, the first device may determine the first time-frequency resource set based on relevant information of the first time-frequency resource set.

[0214] In some embodiments, the relevant information of the second time-frequency resource set includes but is not limited to at least one of the following:

[0215] identification information of the second time-frequency resource set;

[0216] The number P of time domain units in which the second time-frequency resource set is distributed in the time domain;

[0217] The number of time domain units Δp between two adjacent time domain units in the second time-frequency resource set;

[0218] The number N of frequency domain units in which the second time-frequency resource set is distributed in the frequency domain;

[0219] The number of frequency domain units Δ2 between two adjacent frequency domain units in the second time-frequency resource set;

[0220] An index value l0 of a starting time domain unit of the second time-frequency resource set in the time domain;

[0221] An index value k0 of a starting frequency domain unit of the second time-frequency resource set in the frequency domain;

[0222] Wherein, Δ2, Δp, P and N are all positive integers.

[0223] Exemplarily, the second time-frequency resource set may be as shown in FIG7 , where the second time-frequency resource set shown in FIG7 is grouped in the frequency domain and then shifted in the time domain to obtain the first time-frequency resource set.

[0224] In some embodiments, the first parameter set includes a frequency domain grouping parameter D;

[0225] The time domain shift parameter of the time domain unit occupied by the dth frequency domain group in the D frequency domain groups is dΔp / D or -dΔp / D time domain units, where d=0, 1, 2, ..., D-1.

[0226] For example, taking the time domain unit as OFDM symbol and the frequency domain unit as subcarrier, the subcarriers in the second time-frequency resource set are divided into D groups. For the dth group (d=0, 1, 2, ...D-1), the subcarriers included therein are numbered qD+d, where q=0, 1, 2, ..., (N / D)-1.

[0227] Specifically, let N = 15 and D = 3. Then the subcarriers are divided into 3 groups, and N / D = 5. The subcarrier grouping is as follows:

[0228] Group d=0: subcarrier numbers are {0, 1, 2, 3, 4} × 3 + 0 = {0, 3, 6, 9, 12};

[0229] Group d=1: subcarrier numbers are {0, 1, 2, 3, 4} × 3 + 1 = {1, 4, 7, 10, 13};

[0230] Group d=2: The subcarriers are numbered as {0, 1, 2, 3, 4}×3+2={2, 5, 8, 11, 14}.

[0231] Based on the above frequency domain grouping, for the dth frequency domain grouping among the D frequency domain groups, the OFDM symbol indexed as l0+pΔp+dΔp / D or l0+pΔp-dΔp / D in the system is allocated to the perception signal, where p=0, 1, 2,…, P-1.

[0232] An equivalent simplified description of the above statement is that, for the d-th group of subcarriers in the D groups of subcarriers, the OFDM symbols occupied by the perception signal are shifted in the time domain by dΔp / D or -dΔp / D OFDM symbols.

[0233] Taking D = 3 as an example, the second time-frequency resource set after frequency domain grouping and before time domain shifting can be shown in Figure 9(a), and the first time-frequency resource set obtained after frequency domain grouping and time domain shifting can be shown in Figure 9(b). It can be seen that if the resource configuration shown in Figure 9(a) is the same as the second time-frequency resource set shown in Figure 7 (i.e., P = M / D and Δp = DΔp), then the resource configuration shown in Figure 9(b) is the same as the first time-frequency resource set shown in Figure 4.

[0234] In some embodiments, the second time-frequency resource set satisfies at least one of the following:

[0235] The number N of frequency domain units distributed in the frequency domain of the second time-frequency resource set is divisible by D;

[0236] The number of time domain units Δp between two adjacent time domain units in the second time-frequency resource set can be divided by D.

[0237] Specifically, in order to perform the transformation from FIG. 9( a ) to FIG. 9 ( b ), the second time-frequency resource set satisfies at least one of the following:

[0238] The number N of frequency domain units distributed in the frequency domain of the second time-frequency resource set is divisible by D;

[0239] The number of time domain units Δp between two adjacent time domain units in the second time-frequency resource set can be divided by D.

[0240] In some embodiments, the relevant information of the third time-frequency resource set includes but is not limited to at least one of the following:

[0241] identification information of the third time-frequency resource set;

[0242] The number M of time domain units in which the third time-frequency resource set is distributed in the time domain;

[0243] The number of time domain units Δ1 between two adjacent time domain units in the third time-frequency resource set;

[0244] The number Q of frequency domain units of the third time-frequency resource set distributed in the frequency domain;

[0245] The number of frequency domain units Δq between two adjacent frequency domain units in the third time-frequency resource set;

[0246] An index value l0 of a starting time domain unit of the third time-frequency resource set in the time domain;

[0247] An index value k0 of a starting frequency domain unit of the third time-frequency resource set in the frequency domain;

[0248] Wherein, Δ1, Δq, Q and M are all positive integers.

[0249] Exemplarily, the third time-frequency resource set may be as shown in FIG8 , where the third time-frequency resource set shown in FIG8 is grouped in the time domain and then shifted in the frequency domain to obtain the first time-frequency resource set.

[0250] In some embodiments, the time domain grouping parameter included in the second parameter set is D;

[0251] The frequency domain shift parameter of the frequency domain unit occupied by the dth time domain group in the D time domain groups is dΔq / D or -dΔq / D frequency domain units, where d=0, 1, 2, ..., D-1.

[0252] For example, taking the time domain unit as OFDM symbol and the frequency domain unit as subcarrier as an example, the OFDM symbols in the third time-frequency resource set are divided into D groups. For the dth group (d=0, 1, 2, ...D-1), the OFDM symbols included therein are numbered pD+d, where p=0, 1, 2, ..., (M / D)-1.

[0253] Specifically, assume M = 15, D = 3. Then the OFDM symbols are divided into 3 groups, and M / D = 5. The OFDM symbols are grouped as follows:

[0254] Group d=0: OFDM symbols are numbered {0, 1, 2, 3, 4} × 3 + 0 = {0, 3, 6, 9, 12};

[0255] Group d=1: OFDM symbols are numbered {0, 1, 2, 3, 4} × 3 + 1 = {1, 4, 7, 10, 13};

[0256] The d=2nd group: the OFDM symbols are numbered as {0, 1, 2, 3, 4}×3+2={2, 5, 8, 11, 14}.

[0257] Based on the above time domain grouping, for the dth time domain grouping in the D time domain groups, the subcarrier indexed as k0+qΔq+dΔq / D or k0+qΔq-dΔq / D in the system is allocated to the perception signal, where q=0,1,2,…,Q-1, d=0,1,2,…D-1.

[0258] An equivalent simplified description of the above statement is that, for the dth group of OFDM symbols in the D groups of OFDM symbols, the subcarriers occupied by the perception signal are shifted by dΔq / D or -dΔq / D subcarriers in the frequency domain.

[0259] Taking D = 3 as an example, the third time-frequency resource set after time domain grouping and before frequency domain shifting can be shown in Figure 10(a), and the first time-frequency resource set obtained after time domain grouping and frequency domain shifting can be shown in Figure 10(b). It can be seen that if the resource configuration shown in Figure 10(a) is the same as the third time-frequency resource set shown in Figure 8 (i.e., Q = N / D and Δq = DΔq), then the resource configuration shown in Figure 10(b) is the same as the first time-frequency resource set shown in Figure 4.

[0260] In some embodiments, the third time-frequency resource set satisfies at least one of the following:

[0261] The number M of time domain units distributed in the time domain of the third time-frequency resource set is divisible by D;

[0262] The number of frequency domain units Δq between two adjacent frequency domain units in the third time-frequency resource set can be divided by D.

[0263] Specifically, in order to perform the transformation from FIG. 10( a ) to FIG. 10 ( b ), the third time-frequency resource set satisfies at least one of the following:

[0264] The number M of time domain units distributed in the time domain of the third time-frequency resource set is divisible by D;

[0265] The number of frequency domain units Δq between two adjacent frequency domain units in the third time-frequency resource set can be divided by D.

[0266] In some embodiments, the relevant information of the fourth time-frequency resource set includes but is not limited to at least one of the following:

[0267] identification information of the fourth time-frequency resource set;

[0268] The number P of time domain units in which the fourth time-frequency resource set is distributed in the time domain;

[0269] The number of time domain units Δp between two adjacent time domain units in the fourth time-frequency resource set;

[0270] The number Q of frequency domain units of the fourth time-frequency resource set distributed in the frequency domain;

[0271] The number of frequency domain units Δq between two adjacent frequency domain units in the fourth time-frequency resource set;

[0272] An index value l0 of a starting time domain unit of the fourth time-frequency resource set in the time domain;

[0273] An index value k0 of a starting frequency domain unit of the fourth time-frequency resource set in the frequency domain;

[0274] Wherein, Δp, Δq, P and Q are all positive integers.

[0275] Exemplarily, the fourth time-frequency resource set may be as shown in FIG11( a ), where the fourth time-frequency resource set shown in FIG11( a ) is repeated and shifted to obtain the first time-frequency resource set.

[0276] In some embodiments, the repetition parameter included in the third parameter set is D;

[0277] Among them, for the d-th repetition in D repetitions, the frequency domain shift parameter of the frequency domain unit it occupies is dΔq / D or -dΔq / D frequency domain units, and the time domain shift parameter of the time domain unit it occupies is dΔp / D or -dΔp / D time domain units, d = 0, 1, 2,…, D-1.

[0278] Specifically, based on the configuration of the above-mentioned fourth time-frequency resource set, the time-frequency resources that meet the following description are also determined as the time-frequency resources allocated to the perception signal: the RE determined by the subcarrier indexed as l0+qΔq+dΔq / D in the system on the OFDM symbol indexed as l0+pΔp+dΔp / D in the system is the time-frequency domain resource allocated to the perception signal; wherein d=0,1,2,…,D-1 and D is a positive integer.
