Description

Communication methods, communication equipment, communication systems, storage media and software products Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a communication method, communication device, communication system, storage medium, and program product. Background Technology

[0002] In wireless sensing, it is usually necessary to estimate the distance, azimuth angle, and velocity of the target based on the sensing reference signal. Summary of the Invention

[0003] When employing a non-uniform distribution of the sensing reference signal, a large sensing bandwidth results in a large number of frequency-domain subcarriers. Patterns based on coprime sparse distributions require two extremely large and coprime integers. The generated patterns lack sensing reference signals on most Physical Resource Blocks (PRBs), making it difficult to guarantee frequency-domain phase continuity. Furthermore, nested sparse patterns exhibit uneven frequency-domain distribution. Sensing bandwidth / frame length varies with sensing requirements, while patterns based on coprime / nested sparse distributions are strongly correlated with bandwidth or frame length. Without a unified pattern design, the overhead of pattern configuration and indication becomes excessive.

[0004] This disclosure provides communication methods, communication devices, communication systems, storage media, and program products.

[0005] According to a first aspect of the embodiments of this disclosure, a communication method is proposed, performed by a sensing transmitter, the method comprising:

[0006] A first pattern is determined within a sensing measurement cycle, the sensing measurement cycle comprising multiple repeating sub-cycles, the first pattern being used to determine a first position of the resource transmitting the sensing reference signal within the sub-cycle, the first position being non-uniformly distributed;

[0007] Based on the first pattern, a sensing reference signal is sent in each sub-cycle except the last sub-cycle.

[0008] According to a second aspect of the embodiments of this disclosure, a communication method is provided, executed by a sensing receiver, the method comprising:

[0009] A first pattern is determined within a sensing measurement cycle, the sensing measurement cycle comprising multiple repeating sub-cycles, the first pattern being used to indicate a first position of the resource transmitting the sensing reference signal within the sub-cycle, the first position being non-uniformly distributed;

[0010] The sensing reference signal is received in the first sub-cycle to the penultimate sub-cycle according to the first pattern.

[0011] According to a third aspect of the present disclosure, a communication device is provided for performing the communication method described in any one of the first and second aspects.

[0012] According to a fourth aspect of the present disclosure, a communication system is provided, including a sensing transmitter and a sensing receiver, wherein the sensing transmitter is configured to implement the communication method described in the first aspect, and the sensing receiver is configured to implement the communication method described in the second aspect.

[0013] According to a fifth aspect of the present disclosure, a storage medium is provided that stores instructions that, when executed on a communication device, cause the communication device to perform the communication method as described in the first or second aspect.

[0027] This disclosure presents a communication method, communication device, and communication system.

[0028] This disclosure provides communication methods, communication devices, communication systems, storage media, and program products.

[0029] In a first aspect, embodiments of this disclosure propose determining a first pattern within a sensing measurement period, the sensing measurement period comprising multiple repeating sub-periods, the first pattern being used to determine a first position of a resource transmitting the sensing reference signal within the sub-period, the first position being non-uniformly distributed;

[0030] Based on the first pattern, a sensing reference signal is sent from the first sub-cycle to the penultimate sub-cycle.

[0031] In the above embodiments, the sensing transmitter of this disclosure determines a first pattern within a sensing measurement period. The sensing measurement period of this application includes multiple repeating sub-cycles. The first pattern is used to determine the first position of the resource for transmitting the sensing reference signal in the sub-cycle, and the first position is non-uniformly distributed. Based on the first pattern, the sensing transmitter transmits sensing reference information at least from the first sub-cycle to the penultimate sub-cycle within the sensing measurement period. Thus, the sensing reference signal can be transmitted using the first pattern from the first sub-cycle to the penultimate sub-cycle, which can indicate the sensing reference signal more flexibly and with less overhead.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, determining a first pattern for the sensing measurement cycle includes:

[0033] Obtain first information, which includes the index information of the first pattern;

[0034] Based on the index information of the first pattern and the preset first correspondence, the pattern configuration parameters corresponding to the index information of the first pattern are determined; the first mapping relationship is the correspondence between the index information and the pattern configuration parameters.

[0035] The first pattern is determined based on the corresponding pattern configuration parameters.

[0036] In the above embodiments, the sensing transmitter acquires first information, which includes index information of a first pattern. Based on the index information of the first pattern and a preset first correspondence, the pattern configuration parameters corresponding to the index information of the first pattern are determined. The first pattern is determined based on the corresponding pattern configuration parameters, which can accurately obtain the first pattern and improve the efficiency of obtaining the first pattern.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, the first information includes the length of the sub-cycle.

[0038] In the above embodiments, the first information includes the length of the sub-cycle, which allows the sensing transmitter to determine the start and end units of each sub-cycle, thereby accurately transmitting the sensing reference signal.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the length of the sub-cycle is predefined, preconfigured, or configured by higher-layer signaling;

[0040] When the granularity of the length of the sub-cycle is a first unit, the granularity of the resource is a second unit, and the second unit is a sub-unit of the first unit, the length of the sub-cycle is the minimum number of first units including the first length, where the first length is the length from the first second unit to the last second unit in the first pattern.

[0041] When both the length of the sub-cycle and the granularity of the resource are the second unit, the length of the sub-cycle is greater than or equal to the second length, wherein the second length is the length from the first resource transmitting the sensing reference signal to the last resource transmitting the sensing reference signal in the first pattern.

[0042] In the above embodiments, the length of the sub-cycle can be determined by configuration. Depending on whether the granularity of the sub-cycle length is consistent with the granularity of the resource, it can be divided into two ways: the length of the sub-cycle is the minimum number of the first unit including the first length or greater than or equal to the second length. The embodiments of this disclosure achieve a more flexible configuration of the sub-cycle length.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, when the length of the last sub-cycle is less than the lengths of the other sub-cycles, the method further includes:

[0044] If the first information also includes a first indication, a sensing reference signal is transmitted according to the first indication in the last sub-cycle of the sensing measurement cycle.

[0045] If the first information does not include the first indication, a sensing reference signal is sent according to the first pattern in the last sub-cycle of the sensing measurement cycle, or no sensing reference signal is sent in the last sub-cycle of the sensing measurement cycle.

[0046] The first indication is used to indicate the second position of the resource transmitting the sensing reference signal in the last sub-cycle.

[0047] In the above embodiments, for the case where the last sub-cycle is incomplete, if the first information also includes a first indication, then a sensing reference signal is sent in the last sub-cycle according to the first indication, so that the position of the resource transmitting the sensing reference signal in the last sub-cycle is different from the position of the previous sub-cycle; if the first information does not have a first indication, the sensing reference signal can be transmitted in the last sub-cycle based on the first pattern, so that the position of the resource transmitting the sensing reference signal in the last sub-cycle is unevenly distributed, or the sensing reference signal may not be sent in the last sub-cycle.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the second position is unevenly distributed, and the first indication includes a second pattern for determining the second position of the resource transmitting the sensing reference signal in the last sub-cycle;

[0049] The second position is uniformly distributed, and the first indication includes the uniform spacing of the resources for transmitting sensing reference signals in the last sub-cycle.

[0050] In the above embodiments, the second position can be non-uniformly distributed or uniformly distributed. When it is non-uniformly distributed, the first indication includes a second pattern, which is used to determine the second position of the resource transmitting the sensing reference signal in the last sub-cycle. When it is uniformly distributed, the first indication includes a uniform interval of the resource transmitting the sensing reference signal in the last sub-cycle, so that the sensing transmitter determines the position of the resource transmitting the sensing reference signal based on the uniform interval.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the index information includes at least one of a first index and a second index; the sub-period includes at least one of a time-domain sub-period and a frequency-domain sub-period;

[0052] Wherein, the pattern configuration parameters corresponding to the first index are used to determine the first sub-pattern in the first pattern, and the first sub-pattern is used to determine the first position of the time domain resource for transmitting the sensing reference signal in the time domain sub-period;

[0053] The pattern configuration parameters corresponding to the second index are used to determine the second sub-pattern in the first pattern, and the second sub-pattern is used to determine the first position of the frequency domain resource for transmitting the sensing reference signal in the frequency domain sub-period.

[0054] In the above embodiments, the index information includes at least one of a first index and a second index, and the sub-period includes at least one of a time-domain sub-period and a frequency-domain sub-period. Thus, when the sensing transmitter obtains the first index, it can determine the first sub-pattern based on the pattern configuration parameters corresponding to the first index. When it obtains the second index, it can determine the second sub-pattern based on the pattern configuration parameters corresponding to the second index, thereby realizing the periodic transmission of sensing measurement signals in at least one of the time domain and frequency domain during the sensing measurement process.

[0131] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0132] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0133] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0134] In a wireless sensing system, the sensing receiver generally estimates information such as the position, distance, and speed of the sensing target by obtaining information such as the time delay, angle, and Doppler of the sensing reference signal. Since wireless sensing and wireless communication technologies are highly similar, an integrated sensing and communication (ISAC) system can fuse the two technologies to simultaneously achieve communication and sensing functions.

[0135] The performance of sensing accuracy and sensing resolution depends on the configuration of the resources for transmitting the sensing reference signal. Generally speaking, the larger the bandwidth of the sensing reference signal, the higher the sensing distance accuracy and resolution; the longer the duration of the sensing reference signal, the higher the sensing speed accuracy and resolution.

[0136] To obtain accurate terminal position information or other sensing information, a large amount of time-frequency resources often need to be configured. To save the sensing resource overhead, comb is a potential solution. Comb saves resource overhead without reducing sensing accuracy by configuring the sensing reference signal to be equally spaced in the time domain and frequency domain. However, the comb scheme will introduce an estimation ambiguity problem. For example, based on the equally spaced arrangement of OFDM sensing reference signals, the maximum ambiguity distance and maximum ambiguity speed can be deduced. By analyzing the maximum ambiguity distance and maximum ambiguity speed, it can be seen that the smaller the frequency domain interval of the sensing reference signal, the larger the distance non-ambiguity range, and the shorter the transmission period of the sensing reference signal, the larger the speed non-ambiguity range.

[0137] To solve the above problems without sacrificing sensing accuracy, the sensing reference signal can adopt a non-uniform distribution, that is, a time-frequency sparse sensing reference signal design.

[0138] The resources for transmitting the sensing reference signal in the embodiments of the present disclosure can be subcarriers, OFDM symbols, time slots, or PRBs, etc.

[0139] The non-uniform sensing reference signal distribution in the embodiments of the present disclosure can be divided into a sparse arrangement based on co-prime and a sparse arrangement based on nested, as follows: ?

[0140] 1. Sparse arrangement based on co-prime: S = {Mnd + k, n = 0, 1, 2... N - 1} ∪ {Nmd + k, m = 0, 1, 2... ~M - 1}

[0141] Where, d represents the minimum interval between the resources of two adjacent transmitted sensing reference signals, M < N, M and N are a pair of co-prime positive integers, and k represents any positive integer less than d.

[0142] 2. Nested sparse arrangement S={n1d+k,n1=0,1,2...N1}∪{(n2+1)Md+k,n2=0,1,2...N2}

[0143] Where d represents the minimum interval between two adjacent resources transmitting sensing reference signals, wherein the sensing reference signal unit can be a subcarrier / OFDM symbol / slot / PRB, etc., M is a positive integer greater than or equal to N1, N1 and N2 represent the number of sensing reference signal units in two uniformly arranged arrays, and k represents any positive integer less than d.

[0144] Taking the coprime-based sparse arrangement as an example, considering the time-domain resources of the transmitted sensing reference signal, and taking {M=4,N=5,d=2,k=0}, the sequence of the time-domain resources of the transmitted sensing reference signal is {0,8,10,16,20,24,30,32,40,50,60,70}.

[0145] When the sensing bandwidth is large, the number of frequency domain subcarriers is also large. Sparse arrangement based on coprime elements requires two extremely large coprime integers. On the one hand, the generated pattern lacks a sensing reference signal on most PRBs, making it difficult to guarantee frequency domain phase continuity. On the other hand, sparse arrangement based on nesting elements has an uneven distribution in the frequency domain. On the other hand, the sensing bandwidth / frame length varies with sensing requirements, and the sparse pattern based on coprime / nested elements is strongly correlated with the bandwidth / frame length. Therefore, without a unified pattern design, the overhead of the above pattern configuration and indication becomes too large.

[0146] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0147] In step S2101, the sensing transmitter 101 determines the first pattern within the sensing measurement period.

[0148] The sensing measurement cycle of this embodiment includes multiple repeating sub-cycles. A first pattern is used to indicate the first position of the resource transmitting the sensing reference signal in the sub-cycle. The first position is non-uniformly distributed. The sensing transmitter 101 can transmit sensing reference information at least from the first sub-cycle to the penultimate sub-cycle according to the first pattern.

[0149] In some embodiments, resources include at least one of time-domain resources and frequency-domain resources. Time-domain resources are OFDM symbols or time slots. Frequency-domain resources are subcarriers or PRBs.

[0150] In some embodiments, the sensing transmitter 101 can obtain first information, which includes index information of a first pattern. Different index information corresponds to different pattern configuration parameters. The pattern configuration parameters refer to the parameters for configuring the first pattern. When the parameters are different, the configured first pattern is also different.

[0151] The sensing transmitter can pre-establish the correspondence between various index information and pattern configuration parameters, thereby determining the corresponding pattern configuration parameters based on the index information in the first information, and determining the first pattern based on the corresponding pattern configuration parameters.

[0152] For example, when the first position of the resource indicating the transmission of sensing reference signals is a sparse arrangement based on coprime, the pattern configuration parameters include {M,N,k,d}, where d represents the minimum interval between the resources transmitting two adjacent sensing reference signals, M and N are a pair of coprime positive integers, and k represents any positive integer less than d.

[0153] For example, when the first position of the resource indicating the transmission sensing reference signal in the first pattern is a nested sparse arrangement, the pattern configuration parameters include {M,N1,N2,k,d} or {M,k,d}.

[0154] Taking coprime-based sparse arrangement as an example, this embodiment of the disclosure can pre-create four pattern configuration parameters and set corresponding index information for each pattern configuration parameter:

[0155] The above T0 to T3 are four index information, each index information corresponds to a pattern configuration parameter, and different pattern configuration parameters can generate different first patterns.

[0156] In some embodiments, the index information of the first pattern may include at least one of the index of the first sub-pattern (first index) and the index of the second sub-pattern (second index), wherein the first sub-pattern is used to indicate a first location of a time-domain resource for transmitting a sensing reference signal, and the second sub-pattern is used to indicate a first location of a frequency-domain resource for transmitting a sensing reference signal.

[0157] In some embodiments, when the resources include time-domain resources, the first pattern includes a first sub-pattern, thereby the sensing transmitter 101 periodically transmits sensing reference information in the time domain. When the resources include frequency-domain resources, the first pattern includes a second sub-pattern, thereby the sensing transmitter 101 periodically transmits sensing reference information in the frequency domain.

[0158] Please refer to Figure 2B, which exemplarily illustrates a schematic diagram of the repetition of the first pattern within a sensing measurement cycle. As shown in the figure, the length of the sub-cycle determined based on the first pattern is 6 time slots, and the length of the sensing measurement cycle is 36 time slots. Therefore, within one sensing measurement cycle, the sensing transmitter repeatedly transmits sensing reference signals for 6 sub-cycles based on the first pattern. Each time slot contains 14 OFDM symbols. The position and number of OFDM symbols transmitting sensing reference signals in different time slots also differ. For example, in time slot 1, the 1st, 9th, and 11th OFDM symbols transmit sensing reference signals, while in time slot 5, only the 5th OFDM symbol transmits sensing reference signals, and in time slot 6, only the first OFDM symbol transmits sensing reference signals.

[0159] In some embodiments, the first information includes the length of the sub-cycle.

[0160] In some embodiments, where the resource includes a time-domain resource, the sub-period includes a time-domain sub-period TP. a The time-domain sub-period can be granular in terms of time slots, milliseconds, or OFDM symbols.

[0161] In some embodiments, where the resources include frequency domain resources, the sub-period includes a frequency domain sub-period FP. a Frequency domain sub-periods can be granular with subcarriers or PRBs.

[0162] When the granularity of the sub-cycle is a first unit, the granularity of the resource is a second unit, and the second unit is a sub-unit of the first unit, the sub-cycle is the minimum number of first units including a first length.

[0163] Taking time-domain resources as an example, each time slot includes 12 or 14 OFDM symbols. Considering the calculation formula of the first pattern mentioned above, the position of the last OFDM symbol is not necessarily an integer multiple of 14 / 12. However, the time-domain resources of the sensing reference signal are generally measured in time slots or milliseconds (ms), so the length of the sub-period is generally measured in granularity of time slots or milliseconds (ms). In this case, it is necessary to determine the time-domain sub-period. Taking a coprime-based sparse arrangement as an example, let the pattern configuration parameters be {M=4, N=5, d=2, k=0}. The granularity of these pattern configuration parameters is OFDM symbols. The first position of the time-domain resources (OFDM symbols) for transmitting the sensing reference signal constitutes the following sequence {0, 8, 10, 16, 20, 24, 30, 32, 40, 50, 60, 70}.

[0164] For the above coprime-based sparse arrangement, the first length of the first pattern is rounded up to an integer number of time slots, and this is taken as the length of the sub-time domain period:

[0165] In some embodiments, when both the length of the sub-cycle and the granularity of the resource are second units, the length of the sub-cycle is greater than or equal to the second length, wherein the second length is the length from the first resource transmitting the sensing reference signal to the last resource transmitting the sensing reference signal in the first pattern.

[0166] For the coprime-based sparse arrangement described above, taking time-domain resources as an example, when both the period and resource granularity are OFDM symbols, the time-domain sub-period can be any one of the following:

[0167] (1) The length of the time-domain sub-period is taken as the length from the first resource transmitting the sensing reference signal to the last OFDM symbol transmitting the sensing reference signal (i.e., the second length): TP a =(2M-1)Nd+1

[0168] Taking the pattern configuration parameters of the first pattern as {3,4,2,0} as an example, the length of the time-domain sub-period is 40 symbols. It can be understood that the symbol index is generally counted from 0, so 1 needs to be added to (2M-1)Nd to correctly represent the symbol index.

[0169] The length of the time-domain sub-period is defined as a length greater than the first length:

[0170] (2) TP a =(2M-1)Nd+d

[0171] At this point, d is an integer greater than 1. Taking the pattern configuration parameters of the first pattern as {3,4,2,0} as an example, the length of the time domain sub-period is 42 symbol symbols.

[0172] It should be noted that when the sensing reference signal needs to support multiple pattern reuse, for example, when k has multiple values ​​in the pattern configuration parameter, in order to avoid OFDM symbol conflicts between sensing reference signals corresponding to different k values, the period of the first pattern can only be set using the above method (1); when the sensing reference signal does not need to support multiple pattern reuse, for example, when k has only one value, the period of the first pattern can be set using either method (1) or method (2), and there is no problem of OFDM symbol conflicts between transmitted sensing reference signals corresponding to different k values.

[0173] When the time-domain sub-period is longer than the time length of the first sub-pattern, in order to ensure the continuity of the first sub-pattern in the DCA domain, the difference between the first symbol of the next period and the last symbol of the previous period is Nd-1 or Nd+k-1, thus...

[0174] (3) TP a =2MNd+d

[0175] (4) TP a =2MNd+k

[0176] When the second length of the first sub-pattern is L, the length of the sub-cycle can be expressed as: L + p * d, where p is a predefined, pre-configured, or higher-layer signaling configuration constant. For example, based on coprime sparse arrangement, the cycle TP a = (2M-1)Nd+p·d. In particular, when p=0, the first symbol of the second period overlaps with the last symbol of the previous period.

[0177] It is understood that methods 1 to 5 described above are also applicable to determining frequency domain sub-periods, and will not be repeated in the embodiments of this disclosure.

[0178] In some embodiments, the sub-cycle can also be predefined, preconfigured, or configured by higher-level signaling.

[0179] In some embodiments, the number of repetitions of the first sub-pattern is represented by N. t The number of repetitions of the second sub-pattern is represented by N. f If the time-domain frame length of the sensing reference signal is Tslot and the frequency-domain bandwidth is B / PRB, then:

[0180] If the time-domain sub-period is not divisible by the time-domain frame length, it indicates that the last time-domain sub-period is incomplete (i.e., the last sub-period length is shorter than the lengths of other sub-periods), and therefore cannot be filled with an integer number of first sub-patterns to utilize the time-domain resources. Similarly, if the frequency-domain sub-period is not divisible by the frequency-domain bandwidth, it indicates that the last frequency-domain sub-period is incomplete, and therefore cannot be filled with an integer number of second sub-patterns to utilize the frequency-domain resources. Taking a 50MHz bandwidth as an example, referring to the NR resource configuration table, when the subcarrier is 30kHz, the number of subcarriers is 1716, or 143 PRBs. If the length of the sub-period included in the first information is 10 PRBs, then the last sub-period actually only has 3 PRBs, which is less than the bandwidth corresponding to a complete sub-period.

[0181] To address the possibility that the last sub-period (which can be either a frequency domain sub-period or a time domain sub-period) may be incomplete, the embodiments of this disclosure can adopt the following solutions:

[0182] Option 1: The sensing bandwidth or frame length is agreed to be an integer multiple of the bandwidth or duration of the first pattern. In this case, no additional mapping relationship is needed.

[0183] Option 2: Special resource mapping is required for the final non-integer period. That is, when the overall time-domain and frequency-domain resources have the following relationship with the period of the first pattern: (T mod TP)a ) = R t ≠0 (B mod FP a ) = R f ≠0

[0184] Determine the time-domain and frequency-domain resources corresponding to the incomplete sub-cycle. For the reference signal pattern corresponding to the time-frequency resources of the last sub-cycle, consider the following mapping method:

[0185] Method 1: A uniform, equally spaced mapping is used, meaning the interval between any two adjacent resources of the transmission sensing reference signal is the same. For example, if the last time-domain sub-period of the first pattern includes 30 OFDM symbols, and the interval is set to 5 OFDM symbols, then the OFDM symbols of the 6 transmission sensing reference signals in the last time-domain sub-period constitute the following sequence {0, 6, 12, 18, 24, 30}. For Method 1, the information in this disclosure embodiment further includes: a first indication, used to indicate a second position of the resources of the transmission sensing reference signal in the last period, the second position being uniformly distributed. In some embodiments, the first indication includes the uniform interval of the resources of the transmission sensing reference signal in the last period. Please refer to Figure 2C, which exemplarily shows a schematic diagram of the uniform distribution of the resources of the transmission sensing reference signal. It can be seen from the figure that the interval between any two OFDM symbols of the transmission sensing reference signal is 7 OFDM symbols.

[0186] Method 2: Mapping is performed using the first Δk units of the first pattern. For example, if a complete frequency domain sub-period includes 100 subcarriers, but the last frequency domain sub-period is incomplete and only includes 30 subcarriers, and if the sequence of subcarriers transmitting the sensing reference signal in the first 30 subcarriers of the complete frequency domain sub-period is {0,8,10,16,20,24,30}, then for the last frequency domain sub-period, the sequence of subcarriers transmitting the sensing reference signal is also {0,8,10,16,20,24,30}.

[0187] Method 3: Do not map the sensing reference signal, that is, do not transmit the sensing reference signal during incomplete cycles.

[0188] Method 4: A second pattern is used for mapping to determine the second position of the resource transmitting the sensing reference signal in the last sub-cycle. The second position is also unevenly distributed, but unlike the uneven distribution of the first position, in some embodiments, the first indication includes the second pattern.

[0189] It should be noted that if mode 1 is used, the first information also includes a first indication, which includes the uniform interval of the resources transmitting the sensing reference signal in the last sub-cycle; if mode 4 is used, the first information also includes a first indication, which includes a second pattern, which is used to determine a second position of the resources transmitting the sensing reference signal in the last sub-cycle.

[0190] If method 2 or 3 is used, it can be pre-agreed by the protocol, so the first information does not need to include additional information related to the last sub-cycle.

[0191] In some embodiments, when the sensing transmitter 101 is a base station, after obtaining the first information, the sensing transmitter 101 also needs to send the first information to the sensing receiver 102.

[0192] In some embodiments, if the sensing transmitter 101 is a base station and the sensing receiver 102 is a terminal, the sensing transmitter 101 can send the first information to the sensing receiver 102 based on RRC, MAC-CE, and DCI signaling.

[0193] In some embodiments, if both the sensing transmitter 101 and the sensing receiver 102 are base stations, the sensing transmitter 101 can send the first information to the sensing receiver 102 based on core network equipment, wired connection or user unit (Uu) interface.

[0194] In some embodiments, when the sensing transmitter 101 is a terminal, obtaining the first information includes: receiving the first information sent by the base station through RRC, MAC-CE, DCI signaling, core network equipment or PC5 interface.

[0195] In step S2102, the sensing transmitter 101 transmits a sensing reference signal from the first sub-cycle to the penultimate sub-cycle according to the first pattern.

[0196] In some embodiments, since the length of the sensing measurement period is not necessarily divisible by the length of the sub-period, the sensing transmitter 101 transmits the sensing reference signal to the sensing receiver 102 at least from the first sub-period to the penultimate sub-period using the resources for transmitting the sensing reference signal indicated by the first pattern.

[0197] In some embodiments, the sensing receiver 102 may receive first information sent by the base station and determine a first pattern based on the first information. Similarly, the sensing receiver 102 may receive the sensing reference signal at least from the first sub-cycle to the penultimate sub-cycle based on the resources for transmitting the sensing reference signal determined by the first pattern.

[0198] In some embodiments, the first information received by the sensing receiver 102 includes index information of a first pattern. Based on a pre-established correspondence between the index information and pattern configuration parameters, the sensing receiver determines the pattern configuration parameters corresponding to the index information of the first pattern, generates the first pattern, and receives the sensing reference signal based on the resources for transmitting the sensing reference signal indicated by the first pattern. For example, if the sequence of the first positions of the resources for transmitting the sensing reference signal indicated by the first pattern is {0,8,10,16,20,24,30,32,40,50,60,70}, the sensing receiver obtains the sensing reference signal by receiving the resources of the above sequence.

[0199] In some embodiments, the information received by the sensing receiver 102 includes the length of the sub-cycle, so that the number of times the sensing reference signal is repeatedly received according to the first pattern can be determined based on the length. Taking the time-domain sub-cycle as an example, if the length of the time-domain sub-cycle is 6 slots and the sensing measurement period is 36 slots, then the first pattern is repeated 6 times in one sensing measurement period.

[0200] In some embodiments, the information received by the sensing receiver 102 includes a first indication, which indicates a second position of the resource for transmitting the sensing reference signal in the last sub-cycle, so that the sensing receiver receives the sensing reference signal in the last sub-cycle based on each second position indicated by the first indication.

[0201] In some embodiments, the second position is non-uniformly distributed, and the first indication includes a second pattern for determining the second position of the resource transmitting the sensing reference signal in the last sub-cycle.

[0202] In some embodiments, the second position is uniformly distributed, and the first indication includes the uniform spacing of resources transmitting sensing reference signals in the last sub-cycle.

[0203] In some embodiments, if the information received by the sensing receiver 102 does not include the first indication, the sensing receiver may still receive the sensing reference signal based on the first pattern in the last sub-cycle, or may not receive the sensing reference signal in the last sub-cycle.

[0204] The embodiments of this disclosure, based on a periodically repeating first pattern, can more flexibly indicate the resources of the sensing reference signal (at least one of time-domain resources and frequency-domain resources). For example, a base station can configure the sensing reference signal over a large bandwidth to support high latency accuracy requirements. Meanwhile, for some UEs with sensing capabilities but limited bandwidth, only a portion of the aforementioned large-bandwidth sensing reference signal can be detected. Because of the repeating first pattern, the UE can still obtain relatively good measurement accuracy and resolution by detecting only a portion of the sensing reference signal.
