Description

Frequency domain resource allocation method/device/equipment and storage medium Technical field

The present disclosure relates to the field of communication technology, and in particular, to a frequency domain resource allocation method, device, equipment and storage medium.

Background technique

The Integrated Sensing and Communication (ISAC) system integrates radar sensing and communication functions on the same hardware and shares radar and communication frequency bands, which can effectively improve spectrum efficiency.

In related technologies, for synaesthesia systems in multi-user scenarios (that is, there are multiple data receivers in the synaesthesia system), frequency domain resources need to be allocated to each data receiver. The specific method is: allocate frequency domain resources to each data receiver separately. A continuous frequency domain resource. Among them, assume that the total number of subcarriers corresponding to one symbol is 784, and there are 4 data receiving terminals in the synaesthesia system, namely data receiving terminal #A, data receiving terminal #B, data receiving terminal #C, and data receiving terminal #D. Among them, Figure 1 is a schematic diagram of the time-frequency resources of the data receiving end #A in the related art. The white part in Figure 1 represents the subcarriers occupied by the data receiving end #A, and the black part represents the subcarriers not occupied by the data receiving end #A. carrier. And, in Figure 1, the subcarrier positions change randomly within different OFDM symbol times.

However, due to the method of "allocating a continuous frequency domain resource to each data receiving end" in the related technology, the signal correlation between the subcarriers of the data receiving end is relatively large, which in turn affects the detection effect of each data receiving end. Specifically, assuming that the modulation method is Quadrature Phase Shift Keying (QPSK), the signal-to-noise ratio (Signal to Noise Ratio, SNR) is set to 0dB, Figure 2 shows the base station under the allocation method shown in Figure 1 The radar detection stereogram and plan view of data receiving end #A, data receiving end #B, data receiving end #C, and data receiving end #D. Figure 2-1 is the radar detection stereoscopic view, and Figure 2-2 is the radar detection plan view. It can be seen from Figure 2 that when the allocation method shown in Figure 1 is used to allocate frequency domain resources to the data receiving end, there is a speed expansion phenomenon on the speed axis (horizontal axis) when detecting the data receiving end, with higher secondary peaks and smaller side lobes. If there are too many, the detection effect will be unsatisfactory and the distance and speed of the data receiving end cannot be accurately detected.

For example, station (STA), subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile station), mobile station (mobile), remote station (remote station), access point, remote terminal ( remoteterminal), access terminal (access terminal), user device (user terminal) or user agent (useragent). Alternatively, the UE may also be a device of an unmanned aerial vehicle.

Obtain the resource allocation plan sent by network equipment (base station and/or core network equipment);

Determine the resource allocation plan based on the agreement;

Obtain the resource allocation plan sent by the base station, where the resource allocation plan is pre-configured for the core network equipment to the base station;

Obtain the resource allocation plan sent by the base station, where the resource allocation plan is pre-configured to the base station by other base stations;

Determine the resource allocation plan yourself, that is, determine the configuration plan to be adopted based on the actual situation or needs.

Step 302: Use the resource allocation plan to allocate frequency domain resources.

Specifically, in one embodiment of the present disclosure, an ARP interleaver is mainly used to allocate frequency domain resources to the data receiving end in the synaesthesia system. Among them, this part will be introduced in detail in subsequent embodiments.

Step 303: Send allocation information, which is used to determine allocated resources.

In one embodiment of the present disclosure, the allocation information may include frequency domain resources corresponding to each data receiving end.

To sum up, in the frequency domain resource allocation method provided by the embodiment of the present disclosure, the resource allocation scheme is first determined to be: resource allocation based on the ARP interleaver; then, the resource allocation scheme is used to allocate frequency domain resources and send Allocation information used to determine allocated resources. It can be seen from this that in the embodiment of the present disclosure, an ARP interleaver is introduced when allocating resources to the data receiving end, and the ARP interleaver calculation formula is used to scramble the sequence to obtain a new set of different pseudo-random sequences, and Corresponding subcarrier indexes are assigned to respective users to improve radar detection performance.

Figure 4 is a schematic flow chart of a frequency domain resource allocation method provided by an embodiment of the present disclosure. As shown in Figure 4, the frequency domain resource allocation method may include the following steps:

Step 401: Determine the resource allocation plan: resource allocation based on the ARP interleaver.

For detailed introduction to step 401, reference may be made to the description of the above embodiments, and no further description will be made here in the embodiments of the present disclosure.

Step 402: Arrange the N subcarrier indexes in the symbol (such as Orthogonal Frequency Division Multiplexing (OFDM) symbol) to obtain a subcarrier index sequence.

Among them, in an embodiment of the present disclosure, the N subcarrier indexes in the symbol can be arranged from large to small or from small to large. For example, the obtained subcarrier index sequence can be (0,1,...,N -1).

Step 403: Use an ARP interleaver to interleave the subcarrier index sequence to obtain an interleaved subcarrier index sequence.

Specifically, in one embodiment of the present disclosure, a method for interleaving may mainly include the following steps:

Step a. Determine the parameter configuration of the ARP interleaver.

In one embodiment of the present disclosure, the parameter configuration of the ARP interleaver may include at least one of the following:

ARP interleaver calculation formula;

Parameter value rules in the ARP interleaver calculation formula.

Specifically, the above ARP interleaver calculation formula can be:

π(i)=(i×P ₀ +A+d(i))mod N (1)

Among them, i is used to indicate the i-th bit of the interleaved sub-carrier index sequence, π(i) is the value of the i-th bit of the interleaved sub-carrier index sequence, p _i is the factor of N, and A is the compensation parameter, d(i) can be expressed as:

d(i)＝P ₀ ×α(i mod C)+β(i mod C) (2)

Among them, α and β are two vectors with length C, C is the cycle length, α and β are the a and b rows of matrix A _C and B _C , 1≤a≤2, 1≤b≤2C, where, The values of α, β, C, and P ₀ are determined based on the parameter value rules.

The above parameter value rules can be:

N C P ₀ a b 784 4 163 1 1 992 4 85 2 3 1024 8 219 1 6 2048 8 161 1 9

As can be seen from the above parameter value rules, when N is 784, α is 1, b is 1, C is 4, and P ₀ is 163; when N is 992, α is 2, b is 3, C is 4, P ₀ is 85.

And, in one embodiment of the present disclosure, the above-mentioned method of determining the parameter configuration of the ARP interleaver may include at least one of the following:

Obtain the parameter configuration of the ARP interleaver sent by the network device;

Determine the parameter configuration of the ARP interleaver based on the protocol agreement;

Obtain the parameter configuration of the ARP interleaver sent by the base station, where the parameter configuration of the ARP interleaver is pre-configured by the core network equipment to the base station;

Obtain the parameter configuration of the ARP interleaver sent by the base station, where the parameter configuration of the ARP interleaver is pre-configured to the base station by other base stations.

Step b: Determine the values of α, β, C, and P ₀ based on the parameter value rules.

Specifically, the implementation method of this step can be as follows: first determine the values of α, b, C, and P ₀ based on the parameter value rules and the value of N, and then determine α and β based on the values of α, b, and C.

Among them, the method of determining α and β based on the values of α, b, and C can be: first determine the matrices A _C and B _C based on the value of C, where, in response to C=4, the matrices A ₄ and B ₄ can be respectively Expressed as

In response to C=8, matrices A ₈ and B ₈ can be expressed as

Then, α, β are determined from the matrices A _C and B _C based on α, b.

For example, when it is determined that C=4, A=0, P ₀ =163, a=1, b=1, α=[0 0 4 4], β=[0 4 12 8].

Step c. Calculate the interleaved subcarrier index sequence based on α, β, C, P ₀ and the ARP interleaver calculation formula.

Specifically, the values of α, β, C, and P ₀ can be brought into the above formula (2) to obtain d(i), and then d(i) and p _i can be brought into the ARP interleaver calculation formula (1) to calculate the interleaved subcarrier index sequence.

Step 404: Group the interleaved subcarrier index sequences to obtain K subcarrier groups, where K is the number of data receiving terminals.

It should be noted that, in an embodiment of the present disclosure, the K subcarrier groups should meet the following conditions:

In response to N being evenly divisible by K, the number of subcarrier indexes contained in the K subcarrier group is the same (for example, the number can be the value of N being evenly divided by K);

In response to N not being divisible by K, the number of subcarrier indexes contained in d subcarrier groups in the K subcarrier group is the same (the number can be the integer of the quotient of N divided by K plus 1), and the number of subcarrier indexes contained in the other subcarrier groups is the same. The number of subcarrier indexes contained is the same (the number can be an integer of the quotient of N divided by K), and the number of subcarrier indexes contained in d subcarrier group is greater than the number of subcarrier indexes contained in other subcarrier groups. The number is 1 more, where d is the value of N modulo K.

For example, in an embodiment of the present disclosure, assuming that N is 12, K is 2, and N is evenly divisible by K, at this time, the interleaved subcarrier index sequence can be divided into 2 subcarrier groups, and the 2 subcarriers The number of subcarrier indexes included in the group is the same, for example, it can be 6. Based on this, assuming that the interleaved subcarrier index sequence is (0,5,10,3,8,1,6,11,4,9,2,7), then the interleaved subcarrier index sequence can be It is divided into subcarrier group #1 and subcarrier group #1, where subcarrier group #1 is (0,5,10,3,8,1) and subcarrier group #2 is (6,11,4,9, 2,7).

For example, in another embodiment of the present disclosure, assuming that N is 12, K is 5, and N is not divisible by K, then it is determined that the value d after N modulo K is 2. In this case, the interleaved The subcarrier index sequence is divided into 5 subcarrier groups, and the number of subcarrier indexes contained in a certain 2 subcarrier group among the 5 subcarrier groups is 1 more than the number of subcarrier indexes contained in the remaining 3 subcarrier groups. , and the number of subcarrier indexes contained in a certain two subcarrier groups is the same, which is 3. The number of subcarrier indexes contained in the remaining three subcarrier groups in the three subcarrier groups is the same as that of the certain two subcarriers. The number of subcarrier indexes included in the group is different, which is 2. Based on this, assuming that the interleaved subcarrier index sequence is (0,5,10,3,8,1,6,11,4,9,2,7), then the interleaved subcarrier index sequence can be It is divided into subcarrier group #1-subcarrier group #5 in order, where subcarrier group #1 is (0,5,10), subcarrier group #2 is (3,8,1), and subcarrier group #2 is (3,8,1). #3 is (6,11), subcarrier group #4 is (4,9), and subcarrier group #5 is (2,7). Alternatively, the interleaved subcarrier index sequence may be divided into subcarrier group #1 - subcarrier group #5 in no particular order, where subcarrier group #1 is (0,5,2); subcarrier group #2 is (10,3,7); subcarrier group #3 is (8,1); subcarrier group #4 is (6,11); subcarrier group #5 is (4,9).

Step 405: Allocate K subcarrier groups to K data receiving terminals respectively, wherein one data receiving terminal is allocated one subcarrier group, and the subcarrier corresponding to the subcarrier index in each subcarrier group is allocated to the data receiving terminal. terminal frequency domain resources.

In one embodiment of the present disclosure, the K-th subcarrier group may be allocated to the K-th data receiving end as a frequency domain resource. For example, assume that there are two data receiving terminals in the synaesthesia system, namely data receiving terminal #A and data receiving terminal #B, and the obtained K subcarrier groups are: subcarrier group #1 and subcarrier group #2. Then (17,14,11,8,5,2,19,16,13,10) in subcarrier group #1 can be allocated to data receiving end #A as frequency domain resources, and subcarrier group #2 (7,4,1,18,15,12,9,6,3,0) are allocated to data receiving end #B as frequency domain resources.

It can be seen from the above steps 402 and 403 that in the embodiment of the present disclosure, for the sequentially arranged subcarrier index sequence, an ARP interleaver will be used to perform interleaving processing to disrupt the order, resulting in an interleaved subcarrier index sequence that is not arranged in order. . After that, steps 404 and 405 are performed to group the interleaved subcarrier index sequences to obtain subcarrier groups, and allocate the subcarrier groups to the data receiving end. Among them, if the subcarrier indexes in the subcarrier group obtained by grouping are not arranged in order, the subcarrier indexes of the subcarriers allocated to each data receiving end will not be arranged in order, that is, the subcarrier indexes allocated to each data receiving end will not be arranged in order. The subcarriers are discontinuous subcarriers. When the subsequent data receiving end communicates based on the discontinuous subcarriers, the signal correlation between the various subcarriers of the data receiving end can be reduced, ensuring the detection effect of the data receiving end.

Step 406: Send allocation information, which is used to determine allocated resources.

In one embodiment of the present disclosure, the allocation information may include frequency domain resources corresponding to each data receiving end. For example, the allocation information includes: using subcarrier group #1 as the frequency domain resource of the data receiving end #A, and using subcarrier group #2 as the frequency domain resource of the data receiving end #B.

To sum up, in the frequency domain resource allocation method provided by the embodiment of the present disclosure, the resource allocation scheme is first determined to be: resource allocation based on the ARP interleaver; then, the resource allocation scheme is used to allocate frequency domain resources and send Allocation information used to determine allocated resources. It can be seen from this that in the embodiment of the present disclosure, an ARP interleaver is introduced when allocating resources to the data receiving end, and the ARP interleaver calculation formula is used to scramble the sequence to obtain a new set of different pseudo-random sequences, and Corresponding subcarrier indexes are assigned to respective users to improve radar detection performance.

Figure 5a is a schematic flowchart of a frequency domain resource allocation method provided by an embodiment of the present disclosure. As shown in Figure 5a, the frequency domain resource allocation method may include the following steps:

Step 501: Determine the resource allocation plan: resource allocation based on the ARP interleaver.

Step 502: Arrange the N subcarrier indexes in the symbol in order of size to obtain a subcarrier index sequence.

Step 503: Use an ARP interleaver to interleave the subcarrier index sequence to obtain an interleaved subcarrier index sequence.

Step 504: Group the interleaved subcarrier index sequences to obtain K subcarrier groups, where K is the number of data receiving terminals in the synaesthesia system, and each subcarrier group includes at least one subcarrier index sequence.

For detailed introduction to steps 501-504, please refer to the above embodiment description, and will not be described again in the embodiment of the present disclosure.

Step 505: Allocate a subcarrier group to each of the K data receiving ends, where the subcarrier corresponding to the subcarrier index in each subcarrier group is the frequency domain resource allocated to the data receiving end, and the same data receiving end is used under different symbols. The allocated frequency domain resources are different.

Among them, in an embodiment of the present disclosure, it is assumed that the basic parameters of the synaesthesia system are as shown in Table 1, and it is assumed that there are two UEs A and B in the synaesthesia system as data receiving ends, where the two UEs Speed and distance information are shown in Table 2.

Table 1 Basic parameters of synaesthesia system

parameter name numerical value 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 Complete OFDM symbol duration 17.84us Number of BS (base station) antennas 1 Number of UE antennas 1

Table 2 Speed information and distance information of each UE

UE Distance(m) Speed(m/s) A 120 -30 B 120 30 C 40 -30 D 40 30

Based on the basic parameters in Table 1, it can be determined that UE#A, UE#B, UE#C and UE#D each occupy 196 of N=784 subcarriers, and the CPP interleaver calculates UE#A, UE The subcarrier indexes of #B, UE#C and UE#D, and the subcarrier indices of UE#A, UE#B, UE#C and UE#D will randomly change within 560 OFDM symbol times. Among them, Figure 5b is a schematic diagram of time-frequency resources of UE#A when allocating resources using the method shown in Figure 5a provided by the embodiment of the present disclosure. The white part represents the subcarriers occupied by UE#A, and the black part represents the UE #A unoccupied subcarrier. It should be noted that Figure 5b is in the case of C=4, A=0, P ₀ =163, a=1, b=1, α=[0 0 4 4], β=[0 4 12 8] A schematic diagram obtained when resource allocation is performed based on the ARP interleaver calculation formula, and Figure 5c is a stereoscopic view and a plan view of radar detection of UE using the method shown in Figure 5a provided by an embodiment of the present disclosure, wherein Figure 5c -1 is a three-dimensional view of radar detection, and Figure 5c-2 is a plan view of radar detection. It can be seen from Figure 5c that when the allocation method shown in Figure 5a is used to allocate frequency domain resources to UEs, there are no obvious side peaks when detecting UEs, and the four UEs can be distinguished more clearly, and the detection effect is better.

Step 506: Send allocation information, which is used to determine allocated resources.

In one embodiment of the present disclosure, the allocation information may include frequency domain resources corresponding to each data receiving end. For example, the allocation information includes: using subcarrier group #1 as the frequency domain resource of the data receiving end #A, and using subcarrier group #2 as the frequency domain resource of the data receiving end #B.

To sum up, in the frequency domain resource allocation method provided by the embodiment of the present disclosure, the resource allocation scheme is first determined to be: resource allocation based on the ARP interleaver; then, the resource allocation scheme is used to allocate frequency domain resources and send Allocation information used to determine allocated resources. It can be seen from this that in the embodiment of the present disclosure, an ARP interleaver is introduced when allocating resources to the data receiving end, and the ARP interleaver calculation formula is used to scramble the sequence to obtain a new set of different pseudo-random sequences, and Corresponding subcarrier indexes are assigned to respective users to improve radar detection performance.

In addition, the execution subject of the method in Figures 3 to 5a is introduced (in the following content, the data sending end is the base station and the data receiving end is the UE as an example).

Among them, in an embodiment of the present disclosure, the base station (i.e., the data sending end) may perform the above-mentioned method of FIG. 3-FIG. 5a, that is, the base station determines the resource allocation plan to: perform resource allocation based on the ARP interleaver, Resources are allocated based on the resource allocation method, and then allocation information used to determine allocated resources is sent to the UE (ie, the data receiving end), so that the UE determines the frequency domain resources allocated to it based on the allocation information. The method for the base station to determine the resource allocation plan may be at least one of the following: obtaining the resource allocation plan sent by the core network device, determining the resource allocation plan based on the protocol agreement, or obtaining the resource allocation plan sent by other base stations (wherein, the resource allocation plan of other base stations The plan is configured by the core network equipment or configured by another base station), and the base station determines the resource allocation plan by itself. And, it should be noted that in one embodiment of the present disclosure, after the base station as the data sending end determines the resource allocation scheme, it can also send the determined resource allocation scheme to the UE, so that the UE can use the resources based on the resource allocation scheme. The allocation plan determines the frequency domain resources allocated to it.

In another embodiment of the present disclosure, the base station and the UE may respectively perform the above-mentioned methods of FIG. 3-FIG. 5a. That is, both the base station and the UE first determine the resource allocation plan to allocate resources based on the ARP interleaver, and allocate resources based on this resource allocation plan. The method for the UE to determine the resource allocation plan may be: the UE obtains the resource allocation plan sent by the base station, and/or determines the resource allocation plan based on the protocol agreement.

In yet another embodiment of the present disclosure, other base stations (that is, different from the base station serving as the data sending end) may perform the above-mentioned methods in Figures 3-5a. That is, other base stations first determine the resource allocation plan: resource allocation based on the ARP interleaver, and allocate resources based on the resource allocation plan. Then, they send allocation information to the base station as the data sending end and the UE as the data receiving end respectively, so that The two determine the frequency domain resources allocated to the UE.

The determination module 601 is used to determine the resource allocation plan: resource allocation based on the ARP interleaver;

Allocation module 602, used to allocate frequency domain resources using the resource allocation plan;

The sending module 603 is configured to send allocation information, where the allocation information is used to determine allocated resources.

To sum up, in the device provided by the embodiment of the present disclosure, the resource allocation scheme is first determined to be: resource allocation based on the ARP interleaver; then, the resource allocation scheme is used to allocate frequency domain resources and send allocation information. Allocation information is used to determine allocated resources. It can be seen from this that in the embodiment of the present disclosure, an ARP interleaver is introduced when allocating resources to the data receiving end, and the ARP interleaver calculation formula is used to scramble the sequence to obtain a new set of different pseudo-random sequences, and Corresponding subcarrier indexes are assigned to respective users to improve radar detection performance.
