Description

Frequency domain resource allocation method, device and equipment and storage medium

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a method, a device, equipment and a storage medium for allocating frequency domain resources.

Background

The integrated communication sensing (Integrated Sensing and Communication, ISAC) system integrates radar sensing and communication functions on the same hardware and shares radar and communication frequency bands, so that the spectrum efficiency can be effectively improved.

In the related art, for a sense-on system (i.e. a sense-on system having a plurality of data receiving ends) of a multi-user scene, frequency domain resources need to be allocated to each data receiving end, and the specific method is as follows: and respectively allocating a section of continuous frequency domain resources for each data receiving end. The total number of subcarriers corresponding to one symbol is 784, and the sense system has 4 data receiving ends, namely a data receiving end #a, a data receiving end #b, a data receiving end #c and a data receiving end #d, where fig. 1 is a schematic diagram of time-frequency resources of the data receiving end #a in the related art, where a white part in fig. 1 represents subcarriers occupied by the data receiving end #a and a black part represents subcarriers unoccupied by the data receiving end #a. And, the subcarrier locations in the different OFDM symbol times in fig. 1 are randomly varied.

However, the method of "allocating a segment of continuous frequency domain resource to each data receiving end" in the related art may make the signal correlation between the subcarriers of the data receiving ends greater, thereby affecting the detection effect of each data receiving end. Specifically, assuming that the modulation mode is quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK), the signal-to-noise ratio (Signal to Noise Ratio, SNR) is set to 0dB, fig. 2 is a perspective view and a plan view of radar detection for the base station data receiving end #a, the data receiving end #b, the data receiving end #c, and the data receiving end #d in the allocation method shown in fig. 1, where fig. 2-1 is a perspective view of radar detection, and fig. 2-2 is a plan view of radar detection. As can be seen from fig. 2, when the frequency domain resource is allocated to the data receiving end by adopting the allocation method shown in fig. 1, the data receiving end is detected with a speed expansion phenomenon on a speed axis (transverse axis), and the secondary peak is higher, and the side lobe is more, so that the detection effect is not ideal, and the distance and speed of the data receiving end cannot be accurately detected.

step 401, determining a resource allocation scheme as follows: resource allocation is performed based on the ARP interleaver.

The detailed description of step 401 may be described with reference to the above embodiments, which are not described herein.

Step 402, the N subcarrier indexes in the symbol (e.g. orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol) are arranged to obtain a subcarrier index sequence.

Wherein, in one embodiment of the present disclosure, the N subcarrier indexes in the symbol may be arranged from large to small or from small to large, e.g., the resulting subcarrier index sequence may be (0, 1,...

Step 403, interleaving the subcarrier index sequence by using an ARP interleaver to obtain an interleaved subcarrier index sequence.

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

and a, determining the parameter configuration of the ARP interleaver.

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

ARP interleaver calculation formula;

the ARP interleaver calculates the parameter value rule in the formula.

Specifically, the ARP interleaver calculation formula described above may be:

π(i)＝(i×P ₀ +A+d(i))mod N (1)

wherein i is used for indicating the ith bit of the subcarrier index sequence after interleaving, pi (i) is the value of the ith bit of the subcarrier index sequence after interleaving, and p _i Is a factor of N, a is a compensation parameter, and d (i) can be expressed as:

d(i)＝P ₀ ×α(i mod C)+β(i mod C) (2)

wherein alpha and beta are two vectors of length C, C is the cyclic length, and alpha and beta are matrix A _C And B _C Lines a and b of (1.ltoreq.a.ltoreq.2, 1.ltoreq.b.ltoreq.2C, wherein α, β, C, P ₀ Is determined based on the parameter value rule.

The parameter value rule may 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 rule, when N is 784, α is 1, b is 1, C is 4, and P ₀ 163; when N is 992, alpha is 2, b is 3, C is 4, P ₀ 85.

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

acquiring parameter configuration of an ARP interleaver sent by network equipment;

determining the parameter configuration of an ARP interleaver based on protocol conventions;

acquiring parameter configuration of an ARP (address resolution protocol) interleaver sent by a base station, wherein the parameter configuration of the ARP interleaver is preconfigured to the base station by core network equipment;

and acquiring the parameter configuration of an ARP interleaver sent by the base station, wherein the parameter configuration of the ARP interleaver is preconfigured to the base station by other base stations.

Step b, determining alpha, beta and C, P based on parameter value rule ₀ Is a value of (a).

Specifically, the implementation method of the step may be: firstly, determining alpha, b, C and P based on a parameter value rule and the value of N ₀ And then determining alpha and beta based on the values of alpha, b and C.

The method for determining alpha and beta based on the values of alpha, b and C can be as follows: first, a matrix A is determined based on the value of C _C And B _C Wherein, in response to c=4, matrix a ₄ And B ₄ Can be respectively expressed as

Matrix a in response to c=8 ₈ And B ₈ Can be respectively expressed as

Then, from matrix A based on alpha, b _C And B _C And determining alpha and beta.

For example, when c=4, a=0, p is determined ₀ When=163, a=1, b=1, α= [0 04 4 ]]，β＝[0 4 12 8]。

Step c, based on alpha, beta, C, P ₀ And calculating the subcarrier index sequence after interleaving by an ARP interleaver calculation formula.

In particular, it is possible to α, β, C, P ₀ The value of (2) is taken into the formula (2) to obtain d (i), and d (i) and p are then taken into _i And (3) carrying out the ARP interleaver calculation formula (1) to calculate the interleaved subcarrier index sequence.

And step 404, grouping the interleaved subcarrier index sequences to obtain K subcarrier groups, wherein K is the number of data receiving ends.

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

in response to N being divisible by K, the number of subcarrier indexes included in the K subcarrier groups is the same (e.g., the number may be a value of N divisible by K);

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

For example, in one embodiment of the present disclosure, it is assumed that N is 12, K is 2, N is divisible by K, at this time, the interleaved subcarrier index sequence may be divided into 2 subcarrier groups, and the number of subcarrier indexes included in the 2 subcarrier groups is the same, for example, may be 6. Based on this, assuming that the subcarrier index sequence after interleaving is (0,5,10,3,8,1,6,11,4,9,2,7), the subcarrier index sequence after interleaving may be divided into subcarrier group #1 and subcarrier group #1 at this time, wherein 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 and K is 5,N is not divisible by K, the value d=2 after N modulo K is determined, where the interleaved subcarrier index sequence may be divided into 5 subcarrier groups, and the number of subcarrier indexes included in a certain 2 subcarrier groups of the 5 subcarrier groups is 1 more than the number of subcarrier indexes included in the remaining 3 subcarrier groups, and the number of subcarrier indexes included in the certain 2 subcarrier groups is the same as 3, and the number of subcarrier indexes included in the remaining 3 subcarrier groups of the 3 subcarrier groups is different from the number of subcarrier indexes included in the certain 2 subcarrier groups and is 2. Based on this, assuming that the subcarrier index sequence after interleaving is (0,5,10,3,8,1,6,11,4,9,2,7), the subcarrier index sequence after interleaving may be divided into subcarrier group #1 to subcarrier group #5 in order of time, wherein subcarrier group #1 is (0, 5, 10), subcarrier group #2 is (3,8,1), subcarrier group #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 out of order, wherein 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).

And step 405, respectively and correspondingly distributing the K subcarrier groups to the K data receiving ends, wherein one data receiving end is correspondingly distributed with one subcarrier group, and subcarriers corresponding to subcarrier indexes in each subcarrier group are frequency domain resources distributed to the data receiving end.

In one embodiment of the present disclosure, the kth subcarrier group may be allocated as a frequency domain resource to the kth data receiving end. For example, assume that the sense-on system includes two data receiving ends, namely, a data receiving end #a and a data receiving end #b, and the K obtained 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 may be allocated as frequency domain resources to data receiver #a and (7,4,1,18,15,12,9,6,3,0) in subcarrier group #2 may be allocated as frequency domain resources to data receiver #b.

As can be seen from the above steps 402 and 403, in the embodiment of the present disclosure, for the subcarrier index sequences that are sequentially arranged, an ARP interleaver is used to perform interleaving processing to scramble the subcarrier index sequences that are not sequentially arranged and interleaved. Thereafter, the interleaved subcarrier index sequences are grouped to obtain subcarrier groups by performing steps 404 and 405, and the subcarrier groups are allocated to the data receiving end. The subcarrier indexes in the subcarrier groups obtained by grouping are not arranged in sequence, so that the subcarrier indexes of the subcarriers distributed to each data receiving end are not arranged in sequence, namely, the subcarriers distributed to each data receiving end are discontinuous subcarriers, when the subsequent data receiving end communicates based on the discontinuous subcarriers, the signal correlation among the subcarriers of the data receiving end can be reduced, and the detection effect on the data receiving end is ensured.

Step 406, transmitting allocation information, where the allocation information 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: subcarrier group #1 is used as the frequency domain resource of data receiving end #a, and subcarrier group #2 is used as the frequency domain resource of data receiving end #b.

Fig. 5a is a flowchart of a frequency domain resource allocation method according to an embodiment of the present disclosure, where, as shown in fig. 5a, the frequency domain resource allocation method may include the following steps:

Step 501, determining a resource allocation scheme as: resource allocation is performed based on the ARP interleaver.

Step 502, arranging the N subcarrier indexes in the symbol according to the order of magnitude to obtain a subcarrier index sequence.

Step 503, interleaving the subcarrier index sequence by using an ARP interleaver to obtain an interleaved subcarrier index sequence.

Step 504, obtaining K subcarrier groups by grouping the subcarrier index sequences after interleaving, where K is the number of data receiving ends in the sense system, and each subcarrier group includes at least one subcarrier index sequence.

The detailed descriptions of steps 501-504 may be described with reference to the above embodiments, and the embodiments of the disclosure are not described herein.

Step 505, a subcarrier group is allocated to each of the K data receiving ends, where subcarriers corresponding to subcarrier indexes in each subcarrier group are frequency domain resources allocated to the data receiving ends, and the frequency domain resources allocated to the same data receiving end under different symbols are different.

In one embodiment of the present disclosure, it is assumed that basic parameters of a sense system are shown in table 1, and that 2 UEs, a and B, are used as data receiving ends in the sense system, wherein speed and distance information of the 2 UEs are shown in table 2.

TABLE 1 general sense System basic parameters

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
Full OFDM symbol duration	17.84us
BS (base station) antenna number	1
UE antenna count	1

Table 2 speed information and distance information for each UE

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

It can be determined based on the basic parameters in table 1 that UE # A, UE # B, UE #c and UE # D occupy 196 of n=784 subcarriers, and subcarrier indexes of UE # A, UE # B, UE #c and UE # D are calculated by the CPP interleaver, and subcarrier indexes of UE # A, UE # B, UE #c and UE # D are randomly changed in 560 OFDM symbol times. In the time-frequency resource diagram of ue#a when the method shown in fig. 5a is used to allocate resources, in the embodiment of the disclosure in fig. 5b, the white portion indicates subcarriers occupied by ue#a, and the black portion indicates subcarriers unoccupied by ue#a. Note that fig. 5b shows that c=4, a=0, and p ₀ ＝163，a＝1，b＝1，α＝[0 0 4 4]，β＝[0 4 12 8]In the case of (a), a schematic diagram is obtained when resource allocation is performed based on an ARP interleaver calculation formula, and fig. 5c is a perspective view and a plan view of radar detection for a UE by using the method shown in fig. 5a, where fig. 5c-1 is a perspective view of radar detection, and fig. 5c-2 is a plan view of radar detection. As can be seen from fig. 5c, when the UE is detected after the frequency domain resources are allocated to the UE by using the allocation method shown in fig. 5a, four UEs can be more clearly distinguished without obvious side peaks, and the detection effect is better.

Step 506, transmitting allocation information, where the allocation information is used to determine allocated resources.

In addition, the description is made with respect to the execution body of the method of fig. 3 to 5a (in the following, the data transmitting end is taken as a base station, and the data receiving end is taken as a UE as an example).

Among other things, in one embodiment of the present disclosure, the method of fig. 3-5 a described above may be performed by a base station (i.e., a data transmitting end), that is: the base station determines the resource allocation scheme as follows: the resource allocation is performed based on the ARP interleaver, and the resource is allocated based on the resource allocation method, and then allocation information for determining the allocated resource is transmitted to the UE (i.e., the data receiving end), so that the UE determines the frequency domain resource allocated thereto based on the allocation information. The method for determining the resource allocation scheme by the base station may be at least one of the following: acquiring a resource allocation scheme sent by core network equipment, determining the resource allocation scheme based on protocol conventions, acquiring resource allocation schemes sent by other base stations (wherein the resource allocation schemes of the other base stations are configured by the core network equipment or configured by other base stations), and determining the resource allocation scheme by the base stations by themselves. And, it should be noted that, in one embodiment of the present disclosure, after determining the resource allocation scheme, the base station as the data transmitting end may further transmit the determined resource allocation scheme to the UE, so that the UE may determine the frequency domain resource allocated thereto based on the resource allocation scheme.

In another embodiment of the present disclosure, the base station and the UE may perform the methods of fig. 3-5 a, respectively, described above. Namely: the base station and the UE determine the resource allocation scheme as follows: and performing resource allocation based on the ARP interleaver, and allocating resources based on the resource allocation scheme. The method for determining the resource allocation scheme by the UE may be: the UE acquires a resource allocation scheme sent by the base station and/or determines the resource allocation scheme based on protocol conventions.

In yet another embodiment of the present disclosure, the above-described methods of fig. 3-5 a may be performed by other base stations (i.e., different from the base station that is the data transmitting end). Namely: other base stations determine the resource allocation scheme as follows: and performing resource allocation based on the ARP interleaver, allocating resources based on the resource allocation scheme, and then respectively transmitting allocation information to a base station serving as a data transmitting end and a UE serving as a data receiving end so as to ensure that the base station and the UE determine the frequency domain resources allocated for the UE.
