Description

Technical Field

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

[0002] Integrated Sensing and Communications (ISAC) systems (also known as integrated sensing systems, sensing systems, or integrated radar and communication (radcom) systems) have received widespread attention in next-generation wireless communication systems in recent years. Sensing systems can reduce the overall hardware cost of communication and radar systems, improve energy efficiency and spectrum efficiency, and alleviate the current severe spectrum scarcity problem.

[0003] When integrating communication and radar systems, multi-user subcarrier allocation needs to be considered. Related technologies typically use a continuous subcarrier allocation scheme. Specifically, assuming a frequency domain symbol corresponds to a total of 784 subcarriers, and the sensing system has four sensing devices: Sensing Device-A, Sensing Device-B, Sensing Device-C, and Sensing Device-D, Sensing Device-A occupies subcarriers 1-196 consecutively, Sensing Device-B occupies subcarriers 197-392 consecutively, Sensing Device-C occupies subcarriers 393-588 consecutively, and Sensing Device-D occupies subcarriers 589-784 consecutively. Furthermore, Figure 1 and Figure 2 This diagram illustrates the time-frequency domain resources of sensing devices A through D under a continuous subcarrier allocation scheme. The black areas represent unused subcarriers by sensing device A, and the white areas represent subcarriers occupied by sensing device A. Further, refer to... Figure 1 and Figure 2 As shown, there are two schemes for allocating subcarriers in time-domain resources. Scheme 1 involves fixing the subcarrier positions in different time-domain resources (i.e., ...). Figure 1 Scheme 2 involves random variation of subcarrier positions in different time-domain resources (i.e., the subcarrier positions shown in the diagram are not included in the provided text). Figure 2 (Scheme shown).

[0004] However, the resource allocation methods in related technologies can lead to high signal correlation between subcarriers of sensing devices, making it difficult for sensing devices to accurately detect the distance and speed of other sensing devices. For example, assuming the modulation method is Quadrature Phase Shift Keying (QPSK) and the signal-to-noise ratio (SNR) is set to 0dB, Figure 3a and Figure 3b They are respectively in Figure 1 The image shows a stereoscopic and planar view of radar images obtained by sensing device A detecting other sensing devices using the method shown. Figure 4a and Figure 4b They are respectively Figure 2 The image shows a stereoscopic and planar view of radar images obtained by sensing device A detecting other sensing devices using the method shown. Figure 3a and 3b As shown, when Scheme 1 is used to allocate resources to the sensing device, a distance extension phenomenon occurs on the distance axis (vertical axis), such as... Figure 4a and 4b As shown, when Scheme 2 is used to allocate resources to the sensing device, not only does the velocity expansion phenomenon occur on the velocity axis (horizontal axis), but the secondary peak is also high and there are many side lobes, resulting in an unsatisfactory detection effect and an inability to accurately detect the distance and velocity of the UE.

[0053] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0054] The sensing devices involved in this disclosure can refer to user equipment with sensing capabilities, that is, the ability to actively sense and / or be sensed. With the assistance of radar, the communication system can achieve more accurate and efficient mutual sensing between sensing devices.

[0055] Figure 5b This is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of the present disclosure, as shown below. Figure 5b As shown, the resource allocation method may include the following steps:

[0056] Step 501: Determine the resource allocation scheme as follows: allocate resources based on a 5-Permutation Polynomial (5-PP) interleaver.

[0057] In one embodiment of this disclosure, the method can be applied to a self-organizing network, which may include multiple sensing devices that can sense and detect each other. The sensing device can be a user equipment (UE).

[0058] It should be noted that, in one embodiment of this disclosure, the UE can be a device that provides voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a Radio Access Network (RAN). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device from an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0059] Furthermore, in one embodiment of this disclosure, the method for determining the resource allocation scheme described above may include at least one of the following:

[0060] Method a: Determine the resource allocation scheme based on the agreement.

[0061] Specifically, in one embodiment of this disclosure, determining the resource allocation scheme based on the agreement may include at least one of the following:

[0062] Based on the agreement, multiple alternative resource allocation schemes are determined, and the resource allocation scheme is independently selected from the multiple alternative resource allocation schemes;

[0063] The resource allocation scheme is determined directly based on the agreement (i.e., the agreement only stipulates one resource allocation scheme).

[0064] Method b: Determine the resource allocation plan yourself.

[0065] Method c: Determine the resource allocation scheme based on the base station configuration.

[0066] Specifically, in one embodiment of this disclosure, determining the resource allocation scheme based on the base station configuration may include at least one of the following:

[0067] Obtain the resource allocation scheme configured by the base station through semi-static signaling. This semi-static signaling can be Ratio Resource Control (RRC) signaling.

[0068] The system obtains the resource allocation scheme configured by the base station and the associated time-frequency domain resources. Based on the currently used time-frequency domain resources, it determines the corresponding resource allocation scheme. The resource allocation scheme and associated time-frequency domain resources can be configured using the same signaling or separately using different signaling. For example, assuming the time-frequency domain resources configured by the base station associated with "Resource allocation scheme: Resource allocation based on 5-PP interleaver" are: carrier frequency 24GHz, if the carrier frequency of the currently used time-frequency resources is 24GHz, then the resource allocation scheme to be used can be determined as: resource allocation based on 5-PP interleaver.

[0069] The resource allocation scheme configured by the base station through dynamic signaling is obtained. Specifically, in one embodiment of this disclosure, the base station can configure multiple alternative resource allocation schemes through RRC signaling, and then dynamically configure which of the multiple alternative resource allocation schemes to use for resource allocation through dynamic signaling. The dynamic signaling can be Downlink Control Information (DCI) signaling and / or Media Access Control-Control Element (MAC-CE) signaling.

[0070] The system can obtain multiple alternative resource allocation schemes for base station configuration and independently determine the resource allocation scheme from among these alternative schemes.

[0071] Method d: Determine the resource allocation scheme based on the configuration of core network equipment.

[0072] Specifically, in one embodiment of this disclosure, determining the resource allocation scheme based on the configuration of the core network equipment may include at least one of the following:

[0073] Obtain the resource allocation scheme configured by the core network equipment through semi-static signaling.

[0074] Obtain the resource allocation scheme configured for the core network equipment and the time-frequency domain resources associated with the resource allocation scheme, and determine the corresponding resource allocation scheme based on the currently used time-frequency domain resources.

[0075] Obtain the resource allocation scheme configured by the core network equipment through dynamic signaling.

[0076] The system obtains multiple alternative resource allocation schemes for core network equipment configuration and autonomously determines the resource allocation scheme from among these multiple alternative resource allocation schemes.

[0077] The method for configuring resource allocation schemes for core network equipment is similar to that for base station resource allocation schemes, and will not be elaborated further here.

[0078] Step 502: Allocate frequency domain resources according to the resource allocation scheme.

[0079] In one embodiment of this disclosure, resource allocation can be performed based on a 5-PP interleaver. Furthermore, how to allocate frequency domain resources based on a 5-PP interleaver will be described in detail in subsequent embodiments.

[0080] Step 503: Send frequency domain information.

[0081] In one embodiment of this disclosure, the frequency domain information can be used to determine the allocated frequency domain resources. Specifically, the frequency domain information may include the frequency domain resources of each sensing device.

[0082] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0083] Figure 6a This is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of the present disclosure, as shown below. Figure 6a As shown, the resource allocation method may include the following steps:

[0084] Step 601a: Determine the resource allocation scheme as follows: allocate resources based on the 5-PP interleaver.

[0085] Step 602a: Arrange the N subcarrier indices in each symbol to obtain the first subcarrier index sequence corresponding to each symbol.

[0086] In one embodiment of this disclosure, the symbol can be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0087] Furthermore, in one embodiment of this disclosure, the allocation method of the first subcarrier index sequence can be: arranging the subcarrier indices in ascending order or descending order. For example, when the number of subcarriers is N, the first subcarrier index sequence corresponding to the symbol can be (0,1,2,...,N-1) or (N-1,N-2,N-3,...,1,0).

[0088] Step 603a: Use a 5-PP interleaver to interleave the first subcarrier index sequence to obtain the second subcarrier index sequence corresponding to each symbol.

[0089] In one embodiment of this disclosure, the method for obtaining the second subcarrier index sequence corresponding to each symbol through interleaving mainly includes the following steps:

[0090] Step 1: Determine the parameter information of the 5-PP interweaver.

[0091] In one embodiment of this disclosure, the parameter information of the 5-PP interlacer includes at least one of the following:

[0092] 5-PP interleaver algebraic polynomial;

[0093] The decomposition formula corresponding to the 5-PP interleaver;

[0094] The parameter value rules in the algebraic polynomial of the 5-PP interleaver.

[0095] Specifically, in one embodiment of this disclosure, the algebraic polynomial of the 5-PP interleaver is:

[0096] π(i)=(f1·i+f2·i 2 +f3·i 3 +f4·i 4 +f5·i 5 )modN (3)

[0097] Where i is used to indicate the i-th bit of the second subcarrier index sequence, π(i) is the value of the i-th bit of the second subcarrier index sequence, and f1, f2, f3, f4 and f5 are the five interleaving parameters of the 5-PP interleaver. The parameter value rules are used to determine the values ​​of the interleaving parameters f1, f2, f3, f4 and f5.

[0098] Furthermore, in one embodiment of this disclosure, the decomposition formula corresponding to the 5-PP interleaver is:

[0099]

[0100] Where ω(N) is a positive integer, p i It is a factor of N, α N,iThat is the corresponding index.

[0101] Furthermore, in one embodiment of this disclosure, the parameter value takes the following rules:

[0102]

[0103] As shown in the table above, the rules for determining the value of this parameter are specific and can be as follows:

[0104] When p i =2 and α N,1 =1, the interleaving parameter must satisfy the condition (f1+f2+f3+f4+f5)=1mod2;

[0105] When p i =2 and α N,1 >1. The interleaving parameters must satisfy the conditions f1=1mod2, (f2+f4)=0mod2, (f3+f5)=0mod2.

[0106] Furthermore, in one embodiment of this disclosure, the method for determining the parameter information of the 5-PP interleaver described above may include at least one of the following:

[0107] Obtain the parameter information of the 5-PP interleaver sent by the base station. The parameter information of the 5-PP interleaver is pre-configured to the base station by the core network equipment.

[0108] Obtain the parameter information of the 5-PP interleaver sent by the base station. The parameter information of the 5-PP interleaver is pre-configured to the base station by other base stations.

[0109] Obtain parameter information of the 5-PP interleaver sent by network devices (base stations and / or core network devices).

[0110] The parameter information of the 5-PP interleaver is determined based on the agreement.

[0111] Step 2: Decompose N based on the decomposition formula to determine p. i and α N,i The value of .

[0112] For example, in one embodiment of this disclosure, assuming N is 10, N can be decomposed into 2 based on the decomposition formula. 1 x5 = 10, at this point, we can obtain p i =2 and 5, α N,i =1.

[0113] Step 3, based on p i and α N,i The values ​​of the parameters and the rules for taking the values ​​determine the values ​​of the interleaving parameters f1, f2, f3, f4 and f5.

[0114] In one embodiment of this disclosure, p can be determined according to step two. i and α N,i The values ​​of f1, f2, f3, f4 and f5 are determined by the conditions that the interleaving parameters must meet, and then the values ​​of the interleaving parameters f1, f2, f3, f4 and f5 are obtained based on the conditions that the interleaving parameters must meet.

[0115] For example, in one embodiment of this disclosure, it is assumed that the interleaving parameters are determined to be f1 = 199, f2 = 7, f3 = 560, f4 = 777 and f5 = 28 based on the parameter value rules.

[0116] Step 4: Substitute the interleaving parameters into the 5-PP interleaver algebraic polynomial to calculate the second subcarrier index sequence corresponding to each symbol.

[0117] Specifically, in one embodiment of this disclosure, the values ​​of interleaving parameters f1, f2, f3, f4 and f5 are substituted into the 5-PP interleaver algebraic polynomial to calculate the second subcarrier index sequence.

[0118] For example, assuming the first subcarrier index sequence is (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), the corresponding interleaving parameters can be substituted into the 5-PP interleaver algebraic polynomial to calculate the second subcarrier index sequence as (1, 4, 8, 3, 5, 6, 9, 2, 7, 0).

[0119] Step 604a: Divide the second subcarrier index sequence corresponding to each symbol into K subcarrier groups, where K is the number of sensing devices and K is a positive integer. Each subcarrier group includes at least one subcarrier index.

[0120] In one embodiment of this disclosure, the K subcarrier groups can be divided according to the following method:

[0121] In response to N being divisible by K, the number of subcarrier indices contained in the K subcarrier groups is the same;

[0122] In response to N not being divisible by K, the number of subcarrier indices contained in d subcarrier groups out of the K subcarrier groups is the same, the number of subcarrier indices contained in the other subcarrier groups is the same, and the number of subcarrier indices contained in d subcarrier groups is 1 more than the number of subcarrier indices contained in the other subcarrier groups, where d is the value of N modulo K.

[0123] For example, in one embodiment of this disclosure, assuming N is 10 and K is 2, and N is divisible by K, the interleaved subcarrier index sequence can be divided into two subcarrier groups, and the number of subcarrier indices contained in the two subcarrier groups is the same, such as 5.

[0124] For example, if the second subcarrier index is (1, 4, 8, 3, 5, 6, 9, 2, 7, 0), then the first five subcarriers in the second subcarrier index sequence can be divided into subcarrier group #1 (1, 4, 8, 3, 5), and the last five subcarriers in the second subcarrier index sequence can be divided into subcarrier group #2 (6, 9, 2, 7, 0).

[0125] For example, in another embodiment of this disclosure, assuming N is 10, K is 3, and N is not divisible by K, then the value of N modulo K is determined to be d = 1. At this time, the interleaved subcarrier index sequence can be divided into 3 subcarrier groups, and 2 of the 3 subcarrier groups contain the same number of subcarrier indices. The remaining 1 subcarrier group contains a different number of subcarrier indices than the 2 subcarrier groups, and the remaining 1 subcarrier group contains 1 more subcarrier indices than the 2 subcarrier groups.

[0126] For example, the second subcarrier index can be (1, 4, 8, 3, 5, 6, 9, 2, 7, 0). In this case, the first four subcarrier indices in the second subcarrier index sequence can be grouped into subcarrier group #1 (1, 4, 8, 3), the fifth to seventh subcarrier indices can be grouped into subcarrier group #2 (5, 6, 9), and the last three subcarrier indices can be grouped into subcarrier group #3 (2, 7, 0). Alternatively, the first three and the last... The next subcarrier index is divided into subcarrier group #1 (1, 4, 8, 0), the fourth to sixth subcarrier indices in the second subcarrier index sequence are divided into subcarrier group #2 (3, 5, 6), and finally the seventh to ninth subcarrier indices in the second subcarrier index sequence are divided into subcarrier group #3 (9, 2, 7). That is, in the embodiments of this disclosure, the subcarrier indices in the interleaved subcarrier index sequence can be divided in chronological order to obtain subcarrier groups, or they can be divided out of chronological order to obtain subcarrier groups.

[0127] Step 605a: Allocate a subcarrier group for each of the K sensing devices under each symbol, wherein the subcarrier corresponding to the subcarrier index in each subcarrier group is the frequency domain resource allocated to the sensing device.

[0128] In one embodiment of this disclosure, the Kth subcarrier group can be assigned to the Kth sensing device. For example, assume there are two sensing devices in the sensing system, namely sensing device-A and sensing device-B, and the resulting K subcarrier groups are: subcarrier group #1 and subcarrier group #2. Then, subcarrier group #1 can be assigned to sensing device-A, and subcarrier group #2 can be assigned to sensing device-B. At this time, the subcarriers corresponding to the subcarrier index in subcarrier group #1 can be the frequency domain resources assigned to sensing device-A (for example, when subcarrier group #1 is (1, 4, 8, 3, 5), the subcarriers with subcarrier indexes of 1, 4, 8, 3, 5 in the symbol can be determined as the frequency domain resources of sensing device-A). The subcarriers corresponding to the subcarrier index in subcarrier group #2 can be the frequency domain resources assigned to sensing device-B (for example, when subcarrier group #2 is (6, 9, 2, 7, 0), the subcarriers with subcarrier indexes of 6, 9, 2, 7, 0 in the symbol can be determined as the frequency domain resources of sensing device-B).

[0129] It should be noted that, as described in steps 602a and 603a above, in this embodiment of the present disclosure, a 5-PP interleaver is used to interleave the sequentially arranged first subcarrier index sequence to obtain a second subcarrier index sequence. Furthermore, the subcarrier indices in this second subcarrier index sequence are arranged in random order. Then, steps 604a and 605a are executed to group the second subcarrier index sequence into subcarrier groups, which are then allocated to sensing devices. Since the subcarrier indices in the second subcarrier index sequence are arranged in random order, the subcarrier indices in the grouped subcarrier groups are also arranged in random order. This results in the subcarrier indices allocated to each sensing device also being arranged in random order (i.e., non-contiguous). Therefore, when the sensing devices communicate based on non-contiguous subcarriers, the signal correlation between the various subcarriers of the sensing devices can be reduced, ensuring the detection effect of the sensing devices.

[0130] Step 606a: Send frequency domain information.

[0131] In one embodiment of this disclosure, the frequency domain information can indicate the frequency domain resources allocated to each sensing device.

[0132] For example, in one embodiment of this disclosure, based on the content of step 605a above, the frequency domain information can indicate that the frequency domain resources of sensing device-A are subcarrier group #1 and the frequency domain resources of sensing device-B are subcarrier group #2.

[0133] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0134] Figure 6b This is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of the present disclosure, as shown below. Figure 6b As shown, the resource allocation method may include the following steps:

[0135] Step 601b: Determine the resource allocation scheme as follows: allocate resources based on the 5-PP interleaver.

[0136] Step 602b: Arrange the N subcarrier indices in each symbol to obtain the first subcarrier index sequence corresponding to each symbol.

[0137] In one embodiment of this disclosure, the N subcarrier indices of each symbol can be arranged in ascending order so that the first subcarrier index sequence corresponding to each symbol is the same, which is (0,1,2,...,N-1).

[0138] Step 603b: Use a 5-PP interleaver to interleave the first subcarrier index sequence to obtain the second subcarrier index sequence corresponding to each symbol, wherein the second subcarrier sequence corresponding to each symbol is the same.

[0139] As can be seen from the foregoing, in one embodiment of this disclosure, the second subcarrier sequence corresponding to each symbol is specifically calculated based on interleaving parameters f1, f2, f3, f4, and f5. Therefore, whether the second subcarrier sequences corresponding to different symbols are the same mainly depends on whether the interleaving parameters used to calculate the second subcarrier sequences under different symbols are the same. Specifically, when the interleaving parameters used to calculate the second subcarrier sequences under different symbols are different, the second subcarrier sequences corresponding to different symbols will be different. Conversely, when the interleaving parameters used to calculate the second subcarrier sequences under different symbols are the same, the second subcarrier sequences corresponding to different symbols will be the same.

[0140] Furthermore, in this embodiment, only one set of interleaving parameters is determined, and each symbol is calculated using this set of interleaving parameters to obtain the second subcarrier sequence, so that each symbol can correspond to the same second subcarrier sequence.

[0141] For example, assuming the interleaving parameters determined in this step are f1 = 199, f2 = 7, f3 = 560, f4 = 777 and f5 = 28, the second subcarrier sequence corresponding to each symbol can be calculated using these interleaving parameters.

[0142] Step 604b: Divide the second subcarrier index sequence corresponding to each symbol into K subcarrier groups, where K is the number of sensing devices and K is a positive integer. Each subcarrier group includes at least one subcarrier index.

[0143] Step 605b: Allocate a subcarrier group for each of the K sensing devices under each symbol, wherein the subcarrier corresponding to the subcarrier index in each subcarrier group is the frequency domain resource allocated to the sensing device.

[0144] Step 606b: Send frequency domain information.

[0145] For further details regarding steps 601b-606b, please refer to the descriptions in the above embodiments; these details will not be repeated here in the embodiments disclosed herein.

[0146] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0147] Figure 6c This is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of the present disclosure, as shown below. Figure 6c As shown, the resource allocation method may include the following steps:

[0148] Step 601c: Determine the resource allocation scheme as follows: allocate resources based on the 5-PP interleaver.

[0149] Step 602c: Arrange the N subcarrier indices in each symbol to obtain the first subcarrier index sequence corresponding to each symbol.

[0150] Step 603c: Use a 5-PP interleaver to interleave the first subcarrier index sequence to obtain the second subcarrier index sequence corresponding to each symbol, wherein at least some symbols correspond to different second subcarrier sequences.

[0151] As can be seen from the foregoing, in one embodiment of this disclosure, the second subcarrier sequence corresponding to each symbol is specifically calculated based on interleaving parameters f1, f2, f3, f4, and f5. Therefore, whether the second subcarrier sequences corresponding to different symbols are the same mainly depends on whether the interleaving parameters used when calculating the second subcarrier sequences under different symbols are the same. Specifically, when the interleaving parameters used when calculating the second subcarrier sequences under different symbols are different, the second subcarrier sequences corresponding to different symbols will be different. Conversely, when the interleaving parameters used when calculating the second subcarrier sequences under different symbols are the same, the second subcarrier sequences corresponding to different symbols will be the same.

[0152] Furthermore, in this embodiment, multiple sets of different interleaving parameters are determined and applied to calculate the second subcarrier sequence corresponding to all symbols. Therefore, at least two symbols will inevitably use different interleaving parameters to calculate the second subcarrier sequence, meaning that at least some symbols will have different second subcarrier sequences.

[0153] Furthermore, when multiple sets of interleaving parameters are determined, the specific method for assigning which set of interleaving parameters to use to calculate the corresponding second subcarrier sequence for each symbol can be as follows:

[0154] Step a: First, determine the usage percentage corresponding to each set of interleaving parameters. The usage percentages corresponding to each set of interleaving parameters may be different or the same.

[0155] In one embodiment of this disclosure, the method for determining the usage percentage corresponding to each set of interleaving parameters includes at least one of the following:

[0156] The usage percentage for each set of interleaving parameters is determined based on the agreement.

[0157] Determine the usage percentage for each set of interleaving parameters yourself;

[0158] The usage percentage corresponding to each set of interleaving parameters is determined based on the base station configuration;

[0159] The usage percentage of each set of interleaving parameters is determined based on the configuration of the core network equipment.

[0160] For example, in one embodiment of this disclosure, assume there are two sets of interleaving parameters: interleaving parameter #1: f1 = a1, f2 = a2, f3 = a3, f4 = a4, and f5 = a5, and interleaving parameter #2: f1 = b1, f2 = b2, f3 = b3, f4 = b4, and f5 = b5. The usage percentage of interleaving parameter #1 and interleaving parameter #2 can both be 50%, or the usage percentage of interleaving parameter #1 can be 30%, and the usage percentage of interleaving parameter #2 can be 70%.

[0161] Step b: Based on the usage ratio corresponding to each set of interleaving parameters, substitute multiple sets of interleaving parameters into the 5-PP interleaver algebraic polynomial to calculate the second subcarrier index sequence corresponding to each symbol.

[0162] Specifically, when calculating the second subcarrier index sequence for each symbol based on the usage ratio of each set of interleaving parameters, the following should be satisfied: assuming that a set of interleaving parameters has calculated the second subcarrier index sequence for F symbols, then F should be equal to the product of the usage ratio of that set of interleaving parameters and the total number of symbols.

[0163] For example, assuming a total of 560 symbols, and two sets of interleaving parameters: interleaving parameter #1: f1 = a1, f2 = a2, f3 = a3, f4 = a4, and f5 = a5, and interleaving parameter #2: f1 = b1, f2 = b2, f3 = b3, f4 = b4, and f5 = b5. Interleaving parameter #1 is used in 30% of the total, and interleaving parameter #2 is used in 70%. Therefore, interleaving parameter #1 can be used to calculate the second subcarrier sequence of any 560 × 30% = 168 symbols out of the 560 symbols, and interleaving parameter #2 can be used to calculate the second subcarrier sequence of the remaining 560 × 70% = 392 symbols out of the 560 symbols.

[0164] Step 604c: Divide the second subcarrier index sequence corresponding to each symbol into K subcarrier groups, where K is the number of sensing devices and K is a positive integer. Each subcarrier group includes at least one subcarrier index.

[0165] Step 605c: Allocate a subcarrier group for each of the K sensing devices under each symbol, wherein the subcarrier corresponding to the subcarrier index in each subcarrier group is the frequency domain resource allocated to the sensing device.

[0166] Step 606c: Send frequency domain information.

[0167] For further details regarding steps 601c-606c, please refer to the descriptions in the above embodiments; these details will not be repeated here in the embodiments disclosed herein.

[0168] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0169] Figure 7 is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of this disclosure. As shown in Figure 7, the resource allocation method may include the following steps:

[0170] Step 701: Determine the resource allocation scheme as follows: allocate resources based on the 5-PP interleaver.

[0171] Step 702: Arrange the N subcarrier indices in each symbol to obtain the first subcarrier index sequence corresponding to each symbol.

[0172] Step 703: Use a 5-PP interleaver to interleave the first subcarrier index sequence to obtain the second subcarrier index sequence corresponding to each symbol.

[0173] Step 704: Divide the second subcarrier index sequence corresponding to each symbol into K subcarrier groups, where K is the number of sensing devices and K is a positive integer. Each subcarrier group includes at least one subcarrier index.

[0174] Step 705: Assign a subcarrier group to each of the K sensing devices under each symbol, and the subcarrier group number assigned to the same sensing device under different symbols shall be the same.

[0175] For example, in one embodiment of this disclosure, subcarrier groups #1 may be allocated to each of the symbols for sensing device-A.

[0176] Furthermore, in one embodiment of this disclosure, it is assumed that the basic parameters of the sensing system are as shown in Table 1, and that there are four UEs in the sensing system, namely sensing device-A, sensing device-B, sensing device-C and sensing device-D, and the distance information and speed information of the four UEs are shown in Table 2.

[0177] Table 1 Basic parameters of the synesthetic system

[0178] carrier frequency 24GHz Subcarrier spacing 60kHz Number of subcarriers 784 Total symbol bandwidth 47MHz Number of OFDM symbols 560 OFDM prefix duration 1.17us OFDM symbol time 16.67us Full OFDM symbol duration 17.84us

[0179] Table 2 Speed ​​and distance information for each sensing device

[0180] A 120 -30 B 120 30 C 50 -30 D 50 30

[0181] According to the basic parameters of the sensing system in Table 1, sensing devices A through D can each occupy 196 of the 784 subcarriers, and the subcarrier indices of sensing devices A through D can be calculated by a 5-PP interleaver. Figure 7b An embodiment of this disclosure provides an example of using... Figure 7aThe diagram illustrates the time-frequency resources of sensing device-A when allocating resources using the method shown. The white portion represents the subcarriers occupied by sensing device-A, and the black portion represents the subcarriers not occupied by sensing device-A. Figure 7b The allocation scheme remains fixed for 560 OFDM symbol times, meaning that the subcarrier indices of sensing device-A to sensing device-D remain unchanged at different OFDM symbol times.

[0182] And, it should be noted that, Figure 7b This is a schematic diagram obtained when resource allocation is performed based on the 5-PP interleaver function, with the interleaving parameters f1 = 199, f2 = 7, f3 = 560, f4 = 777, and f5 = 28 substituted into the calculation. Figure 7c and Figure 7d Each of the embodiments provided in this disclosure adopts an application Figure 7a The method shown generates radar detection stereo and plan views of the sensing device, whereby... Figure 7c A three-dimensional image of radar detection. Figure 7d This is a radar detection plan view. (By...) Figure 7c and Figure 7d It can be seen that although the side lobes are quite obvious when detecting sensing devices, the distance spread phenomenon on the distance axis (vertical axis) is suppressed, thus optimizing the detection effect.

[0183] Step 706: Send frequency domain information.

[0184] For a detailed description of steps 701-706, please refer to the above embodiments. They will not be repeated here in this disclosure.

[0185] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0186] Figure 8a This is a flowchart illustrating a resource allocation method in a communication system provided by an embodiment of the present disclosure, as shown below. Figure 8a As shown, the resource allocation method may include the following steps:

[0187] Step 801: Determine the resource allocation scheme as follows: allocate resources based on the 5-PP interleaver.

[0188] Step 802: Arrange the N subcarrier indices in each symbol to obtain the first subcarrier index sequence corresponding to each symbol;

[0189] Step 803: Use a 5-PP interleaver to interleave the first subcarrier index sequence to obtain the second subcarrier index sequence corresponding to each symbol.

[0190] Step 804: Divide the second subcarrier index sequence corresponding to each symbol into K subcarrier groups, where K is the number of sensing devices and K is a positive integer. Each subcarrier group includes at least one subcarrier index.

[0191] Step 805: Assign a subcarrier group to each of the K sensing devices under each symbol, and the subcarrier group number assigned to the same sensing device is different under at least some symbols.

[0192] For example, in one embodiment of this disclosure, the first symbol may be used to assign subcarrier group #1 to sensing device-A, the second symbol may be used to assign subcarrier group #2 to sensing device-A, the third symbol may be used to assign subcarrier group #3 to sensing device-A, and so on.

[0193] Furthermore, in one embodiment of this disclosure, it is assumed that the basic parameters of the sensing system are as shown in Table 1, and that there are four UEs in the sensing system, namely sensing device-A, sensing device-B, sensing device-C and sensing device-D, and the distance information and speed information of the four UEs are shown in Table 2.

[0194] According to the basic parameters of the sensing system in Table 1, sensing devices A through D can each occupy 196 of the 784 subcarriers, and the subcarrier indices of sensing devices A through D can be calculated by a 5-PP interleaver. Figure 8b An embodiment of this disclosure provides an example of using... Figure 8a The diagram illustrates the time-frequency resources of sensing device-A when allocating resources using the method shown. The white portion represents the subcarriers occupied by sensing device-A, and the black portion represents the subcarriers not occupied by sensing device-A. For example... Figure 8b As shown, the allocation scheme changes randomly within 560 OFDM symbol times, meaning that the subcarrier indices of sensing devices A to D change randomly at different OFDM symbol times.

[0195] In addition, it should be noted that, Figure 8b This is a schematic diagram obtained when resource allocation is performed based on the 5-PP interleaver function, with the interleaving parameters f1 = 199, f2 = 7, f3 = 560, f4 = 777, and f5 = 28 substituted into the calculation. Figure 8c and Figure 8dEach of the embodiments provided in this disclosure is based on Figure 8a The method shown presents a three-dimensional and two-dimensional view of the radar detection of the sensing device. For example... Figure 8c and Figure 8d As shown, there are no obvious side peaks when detecting the sensing devices, and the four sensing devices can be observed more clearly, indicating that the detection effect is obviously better.

[0196] Step 806: Send frequency domain information.

[0197] For a detailed description of steps 801-806, please refer to the above embodiments. They will not be repeated here in this disclosure.

[0198] In summary, the resource allocation method in the communication system provided in this disclosure first determines the resource allocation scheme as follows: resource allocation is performed based on a 5-PP interleaver, then frequency domain resources are allocated according to the resource allocation scheme, and finally, frequency domain information is sent to determine the allocated frequency domain resources. Therefore, by introducing a 5-PP interleaver to allocate resources to sensing devices in this disclosure, it is possible to avoid allocating continuous subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.

[0199] It is understood that although a specific number of user devices is described in the embodiments of this disclosure, the number is merely exemplary and this disclosure does not limit the specific number of user devices.

[0200] The following content is related to the above. Figures 5b-8a The method is used to introduce the subject that can execute this method (the following explanation uses the UE as an example of a sensing device).

[0201] In one embodiment of this disclosure, the above-mentioned Figures 5b-8a The method can be executed independently by the base station. That is, the base station determines the resource allocation method based on the 5-PP interleaver and configures it to the UE. The UE performs resource transmission based on the base station's configuration. Specifically, the base station determines the resource allocation scheme as follows: resource allocation is performed based on the 5-PP interleaver (the method for the base station to determine the resource allocation scheme can be referred to steps 501, methods a to d). Then, the base station allocates frequency domain resources according to the determined resource allocation scheme and sends the frequency domain information used to determine the allocated resources to the sensing device, so that the sensing device can determine the frequency domain resources allocated to it based on the frequency domain information. Furthermore, it should be noted that in one embodiment of this disclosure, after determining the resource allocation scheme, the base station can also send the determined resource allocation scheme to the UE, so that the UE can determine the frequency domain resources allocated to it based on the resource allocation scheme.

[0202] In another embodiment of this disclosure, Figure 5- Figure 8a Both methods can be executed by the base station and the UE. Specifically, both the base station and the UE can first determine the resource allocation scheme as follows: resource allocation is performed based on the 5-PP interleaver, and frequency domain resources are allocated based on this resource allocation scheme. The method for the UE to determine the resource allocation scheme can refer to steps 501, methods a to c.

[0203] In yet another embodiment of this disclosure, Figure 5 above- Figure 8a The method can be executed by other base stations. Specifically, other base stations first determine the resource allocation scheme as follows: resource allocation is performed based on the 5-PP interleaver, and frequency domain resources are allocated according to the resource allocation scheme. Then, frequency domain information is sent to the base station and UE in the sensing system respectively, so that the two can determine the frequency domain resources allocated to the sensing device.

This frequency domain information is used to determine the allocated frequency domain resources. Therefore, it can be seen that in this disclosure embodiment, 5-PP is introduced.

[0209] Using an interleaver to allocate resources to sensing devices can avoid allocating consecutive subcarriers to sensing devices, reduce the correlation between subcarriers of sensing devices, optimize the frequency domain resources of the sensing system, and thus improve the sensing and detection resolution and performance of the sensing system.
