Description

Resource allocation method/device/equipment and storage medium in communication system Technical field

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

Background technique

The Integrated Sensing and Communications (ISAC) system (i.e., synaesthesia integrated system, or synaesthesia system, or communication radar integration (radar and communication, radcom) system) aims to organically integrate communication systems and perception systems. Using the same transceiver, the same spectrum resources and the same hardware platform, the moving target sensing and detection function is completed based on the traditional communication system. Compared with traditional independent communication systems and perception systems, synaesthesia systems can efficiently utilize precious spectrum resources and combine the two in hardware, making communication and perception mutually beneficial, thereby achieving higher performance and a wider range of applications. Application scope. As a result, the synaesthesia system has become one of the potential key technologies for the next generation of wireless communication systems.

Among them, when the communication system and the radar system are integrated, the subcarrier allocation of multiple sensing devices needs to be considered. In related technologies, a continuous subcarrier allocation scheme is usually used to allocate subcarriers to different sensing devices. Specifically, assume that the total number of subcarriers corresponding to one frequency domain symbol is 784, and there are 4 sensing devices (such as user equipment ( User Equipment (UE)), respectively, are UE-A, UE-B, UE-C, and UE-D. Among them, UE-A occupies the 1-196th consecutive subcarriers, and UE-B occupies the 197th-392nd consecutive subcarriers. For subcarriers, UE-C occupies the 393-588th consecutive subcarriers, and UE-D occupies the 589th-784th consecutive subcarriers. And, Figure 1 and Figure 2 are schematic diagrams of time-frequency domain resources from UE-A to UE-D under the continuous subcarrier allocation scheme. The subcarriers not occupied by UE-A are represented by black parts, and the subcarriers occupied by UE-A are represented by The white part indicates. And, as shown in Figure 1, the subcarrier locations allocated to the same UE in different time domain resources can be fixed. Referring to Figure 2, the subcarrier locations allocated to the same UE in different time domain resources can also be random. Variety.

However, the continuous allocation scheme in the related art will cause the subcarriers allocated to the UE to be continuous, which will lead to large signal correlation, which will affect the detection effect of the sensing device. For example, assuming that the modulation method is Quadrature Phase Shift Keying (QPSK) and the signal-to-noise ratio (Signal to Noise Ratio, SNR) is set to 0dB, Figure 3a and Figure 3b are respectively under the method shown in Figure 1 The stereoscopic view and plan view of the radar image of UE-A detecting other UEs. Figure 4a and Figure 4b are respectively the stereoscopic view and plan view of the radar image of UE-A detecting other UEs under the method shown in Figure 2. As shown in Figures 3a and 3b, when the method shown in Figure 1 is used to allocate resources to UE, when UE-A detects other UEs, the distance expansion phenomenon will occur on the distance axis (vertical axis), as shown in Figures 4a and 4b. shows that when the method shown in Figure 2 is used to allocate resources to UE, when UE-A detects other UEs, not only will the speed expand on the speed axis (horizontal axis), but the secondary peak will be higher and there will be more side lobes. As a result, the detection effect is not ideal and the distance and speed of other UEs cannot be accurately detected.

Obtain the resource allocation plan configured by the base station and the time-frequency domain resources associated with the resource allocation plan, and determine the corresponding resource allocation plan based on the currently used time-frequency domain resources. For example, in one embodiment of the present disclosure, it is assumed that the base station configures "time-frequency domain resources: subcarrier spacing 60KHz" and "resource allocation scheme: resource allocation based on DRP interleaver". Then, if the subcarrier spacing of the currently used time domain resources is 60KHz, it can be determined that the corresponding resource allocation scheme is: resource allocation based on a DRP interleaver.

The information is used to determine allocated resources. It can be seen from this that in the embodiments of the present disclosure, a DRP interleaver is introduced to allocate resources to the sensing device, so as to allocate non-consecutive subcarriers to the sensing device, thereby reducing the correlation between the subcarriers of the sensing device and ensuring that the sensing device It can accurately detect the distance and speed of other sensing devices, enhancing the sensing effect and performance.

Figure 6 is a schematic flowchart of a resource allocation method provided by an embodiment of the present disclosure. As shown in Figure 6a, the resource allocation method may include the following steps:

Step 601: Determine the resource allocation plan: resource allocation based on the DRP weaver.

Step 602: Sequentially arrange the N subcarrier indexes in the symbol to obtain a subcarrier index sequence.

Among them, in an embodiment of the present disclosure, for example, N subcarrier indexes in Orthogonal Frequency Division Multiplexing (OFDM) symbols can be arranged.

And, in an embodiment of the present disclosure, the ways of arranging the subcarrier index sequence may include the following two methods:

Arrange in order from small to large. For example, when the number of subcarriers is N, the arranged subcarrier index sequence can be: (0, 1, 2,..., N-1); or

Arrange in order from large to small. For example, when the number of subcarriers is N, the arranged subcarrier index sequence can be: (N-1, N-2, N-3, ..., 1, 0).

Step 603: Use the DRP interleaver to interleave the subcarrier index sequence to obtain an interleaved subcarrier index sequence.

Among them, in an embodiment of the present disclosure, the interleaving process may specifically include the following steps:

Step A: Determine the parameter information of the DRP interleaver.

Wherein, in one embodiment of the present disclosure, the parameter information of the DRP interleaver includes at least one of the following:

DRP interleaver algebraic formula;

Parameter value rules in the algebraic formula of DRP interleaver.

Specifically, the above algebraic formula of the DRP interleaver is;

π _b (i)=(s+P·i)mod N (2)

π(i)＝π _a (π _b (π _c (i))) (4)

Among them, i is used to indicate the i-th bit of the interleaved subcarrier index sequence, π(i) is the value of the i-th bit of the interleaved subcarrier index sequence, r is the read jitter vector of length R, and w is A write jitter vector of length W, P represents the regular interleaver period, and s represents a constant offset, where the values of s, P, R, W, r and w are determined based on the parameter value rules.

And, in an embodiment of the present disclosure, the parameter value rule is:

N s P R W r w 784 73 25 7 7 (2 5 1 0 4 6 3) (6 3 2 4 0 1 5) 784 13 33 7 7 (1 0 3 5 2 4 6) (3 2 6 4 5 1 0) 6144 14 263 2 3 (1 0) (2 1 0) 6144 19 107 3 2 (1 0 2) (1 0)

As shown in the table above, the specific value rules for this parameter can be:

When N=784, according to the parameter value rules, you can choose s=73, P=25, R=7, W=7, r=(2 5 1 0 4 6 3) and w= (6 3 2 4 0 1 5); Alternatively, you can also choose s=13, P=33, R=7, W=7, r=(1 0 3 5 2 4 6) and w= (3 2 6 4 5 1 0).

It should be noted that N can have multiple values, and each value of N corresponds to a parameter value rule. The above table only uses N=784 and N=6144 as examples for the parameter value rules. introduced. However, the content of the above table is not limited to this. In addition to N=784 and N=6144, the corresponding parameter value rules when N is other values are also within the scope of the present disclosure.

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

Obtain the parameter information of the DRP interleaver sent by the network device.

Determine the parameter information of the DRP interleaver based on the protocol agreement.

Step B: Determine the values of s, P, R, W, r and w based on N and parameter value rules.

For example, in one embodiment of the present disclosure, when N=6144, it can be determined based on parameter rules that s=14, P=263, R=7, W=7, r=(1 0) and w=(2 10).

Step C: Calculate the interleaved subcarrier index sequence based on the values of s, P, R, W, r and w and the DRP interleaver algebraic formula.

Specifically, in an embodiment of the present disclosure, the values of s, P, R, W, r and w can be first brought into the above-mentioned DRP interleaver algebraic formula (ie, the above-mentioned formula (1) to formula (3) )), then first calculate the value of π _c (i) according to formula (3), and use the value of π _c (i) as i in formula (2) to calculate the value of π _b (i), and finally The value of π a (i) is calculated using the value of π _b (i) as i in the formula (1), and the value of π _a (i) is _regarded as π(i). Among them, the value of i in π(i) is consistent with the value of i in formula (3). For example, assuming that you want to calculate the value π (1) of the first bit of the interleaved subcarrier index sequence, you can bring i = 1 into formula (3) to calculate the value of π _c (1) as X _{, then use} The value of π _a (Y), where the value of π _a (Y) is the value of π (1).

For example, in an embodiment of the present disclosure, assuming N=15, the sequence before interleaving is (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14), the calculated interleaved sequence may be, for example, (10, 6, 9, 3, 11, 14, 7, 0, 2, 8, 13, 1, 4, 12, 5).

In addition, it should be noted that the interleaved subcarrier index sequences corresponding to different symbols may be the same or different.

Step 604: Group the interleaved subcarrier index sequences to obtain K subcarrier groups, where K is the number of sensing devices, K is a positive integer, and each subcarrier group includes at least one subcarrier index sequence.

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

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 of subcarrier indexes contained in other subcarrier groups is the same, and the number of subcarrier indexes contained in the d subcarrier group is the same. The number of included subcarrier indexes is 1 more than the number of subcarrier indexes included in other subcarrier groups, where d is the value of N modulo K.

For example, in an embodiment of the present disclosure, assuming that N is 15, K is 3, and N is evenly divisible by K, at this time, the interleaved subcarrier index sequence can be divided into 3 subcarrier groups, and the 3 subcarriers The number of subcarrier indexes included in the group is the same, for example, it can be 5.

For example, the interleaved subcarrier index sequence is (10, 6, 9, 3, 11, 14, 7, 0, 2, 8, 13, 1, 4, 12, 5). At this time, the interleaved subcarriers can be The first five in the subcarrier index sequence are divided into subcarrier group #1 (10, 6, 9, 3, 11), and the sixth to tenth subcarriers in the interleaved subcarrier index sequence are divided into subcarriers Carrier group #2 (14, 7, 0, 2, 8) divides the last five interleaved subcarrier index sequences into subcarrier group #3 (13, 1, 4, 12, 5).

For example, in another embodiment of the present disclosure, assuming that N is 15, K is 4, and N is not divisible by K, then it is determined that the value d after N modulo K is 3. In this case, the interleaved The subcarrier index sequence is divided into 4 subcarrier groups, and there are 3 subcarrier groups in the 4 subcarrier groups that contain the same number of subcarrier indexes. The remaining 1 subcarrier group in the 4 subcarrier groups contains The number of subcarrier indexes is different from the number of subcarrier indexes contained in the aforementioned 3 subcarrier groups. At the same time, the number of subcarrier indexes contained in the remaining 1 subcarrier group is greater than the number of subcarrier indexes contained in the aforementioned 3 subcarrier groups. The number of subcarrier indexes is 1 less.

For example, the interleaved subcarrier index sequence may be the above (10, 6, 9, 3, 11, 14, 7, 0, 2, 8, 13, 1, 4, 12, 5). At this time, the first four in the interleaved subcarrier index sequence can be divided into subcarrier group #1 (10, 6, 9, 3) in order, and the fifth to fourth in the interleaved subcarrier index sequence can be divided into The eight subcarrier indexes are divided into subcarrier group #2 (11, 14, 7, 0), and the ninth to twelfth subcarrier indexes in the interleaved subcarrier index sequence are divided into subcarrier group #3 (2 , 8, 13, 1) Finally, the last three subcarrier indexes in the interleaved subcarrier index sequence are divided into subcarrier group #4 (4, 12, 5). Alternatively, the first three and the third to last subcarrier index in the interleaved subcarrier index sequence can be divided into subcarrier group #1 (10, 6, 9, 4), and the interleaved subcarrier index sequence can be The fourth to sixth and penultimate subcarrier indexes are divided into subcarrier group #2 (3, 11, 14, 12), and the seventh to ninth and last subcarrier indexes in the interleaved subcarrier index sequence are A subcarrier index is divided into subcarrier group #3 (7, 0, 2, 5), and finally the tenth to twelfth subcarrier index in the interleaved subcarrier index sequence is divided into subcarrier group #4 ( 8, 13, 1). That is, in the embodiment of the present disclosure, K subcarrier groups can be obtained by dividing in sequence, or the subcarrier indexes in the interleaved subcarrier index sequence can be divided out of order to obtain K subcarrier groups.

Step 605: Allocate K subcarrier groups to K sensing devices in one-to-one correspondence, where the subcarriers corresponding to the subcarrier index in each subcarrier group are frequency domain resources allocated to the sensing devices.

Among them, in an embodiment of the present disclosure, K sensing devices may be assigned one-to-one corresponding K subcarrier groups. As an example, assume that there are three sensing devices in the synaesthesia system, namely sensing device-A, sensing device-B, and sensing device-C, and the three subcarrier groups obtained are: subcarrier group #1, subcarrier group #2 and subcarrier group #3. Then the corresponding subcarrier group #1 can be assigned to the sensing device-A, the corresponding subcarrier group #2 can be assigned to the sensing device-B, and the corresponding subcarrier group #3 can be assigned to the sensing device-C.
