The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The following describes background art and related terms of the present application with reference to fig. 1, where fig. 1 is a schematic structural diagram of a resource block according to an embodiment of the present application.

Resource Block (RB): the 1 resource block may be formed by 7 orthogonal frequency division multiplexing symbols in a time domain, and may be formed by 12 subcarriers in a frequency domain, where the resource block in this embodiment is described only in the frequency domain direction, that is, one resource block may include 12 subcarriers. One subcarrier is spaced 15kHz apart. One RB is 12 x 15KHZ in the frequency domain.

The resource blocks are continuous in the frequency domain, and the number of the resource blocks is related to the frequency bandwidth, for example, there are 100 resource blocks in the 20MHz bandwidth and 50 resource blocks in the 10MHz bandwidth.

Resource Element (RE): namely, one subcarrier in the frequency domain and one orthogonal frequency division multiplexing symbol in the time domain, in the frequency domain direction, 12 resource slices can form one resource block. The spacing of each resource slice is 15 KHZ.

③ direct current subcarrier (DC subcarrier): in an orthogonal frequency division multiplexing subcarrier architecture, a central position is actually set to be 0, which is not used and is called as a direct current subcarrier, the direct current subcarrier only exists in a Long Term Evolution (LTE) system, when the total number of resource blocks in an effective bandwidth in the system is an even number, the direct current subcarrier generally does not exist, and when the total number of the resource blocks in the effective bandwidth in the system is an odd number, the direct current subcarrier exists in the middle resource block, but a protocol specifies that the direct current subcarrier does not transmit any data symbol, and has no other purposes except occupying 15 KHZ.

In a long term evolution system, a New Radio (NR) system, a 6G network system, or the like, it is difficult for an optical filter to achieve flatness of the entire frequency band, and the wider the bandwidth, the larger the fluctuation, so that the spectrum needs to be compensated in the baseband, and extra channel loss is reduced as much as possible.

The existing signal compensation method has overlarge operation amount and unsatisfactory performance of approximate compensation when time domain compensation is adopted, 12 resource pieces in a resource block cannot be aligned by adopting frequency domain compensation, and the signal compensation process is very complicated due to the existence of direct current subcarriers.

In order to solve the above problem, embodiments of the present application provide a signal compensation method and a related apparatus, which can be applied to communication network systems such as an NR system and an LTE system, and consume fewer resources, thereby greatly improving the efficiency and performance of signal compensation.

After introducing an application scenario of the signal compensation method of the present application, a signal compensation method in the embodiment of the present application is described below with reference to fig. 3, where fig. 3 is a schematic flow chart of the signal compensation method provided in the embodiment of the present application, and is used for compensating a frequency spectrum of a resource block, and the method specifically includes the following steps:

step 301, determining a first spectral compensation value for a first resource block and a second spectral compensation value for a second resource block.

The first resource block and the second resource block respectively include at least one resource slice, the first resource block and the second resource block may be adjacent resource blocks or non-adjacent resource blocks, the first resource slice may be any one of the resource slices included in the first resource block, and the second resource slice may be any one of the resource slices included in the second resource block, which is not limited specifically herein.

In one possible embodiment, the first spectrum compensation value corresponding to the first resource slice may be determined first, and then the second spectrum compensation value corresponding to the second resource slice may be determined based on a preset fitting order, a sampling rate, and the number of resource slices between the first resource slice and the second resource slice.

Therefore, by determining the first spectrum compensation value for the first resource block and the second spectrum compensation value for the second resource block, reference can be provided for subsequent signal compensation, and an accurate spectrum compensation value of each resource slice can be obtained without actually measuring each resource slice.

Step 302, calculating a spectrum compensation increment across resource slices based on the number of resource slices between a first resource slice in the first resource block and a second resource slice in the second resource block;

the spectrum compensation increment may be understood as a value added during spectrum compensation of a subsequent resource slice relative to a previous resource slice, and a spectrum compensation difference between the first spectrum compensation value and the second spectrum compensation value may be determined first, and then the spectrum compensation increment may be determined based on the number of resource slices between the first resource slice and the second resource slice and the spectrum compensation difference. For example, if the number of resource slices between the first resource slice and the second resource slice is 12 and the spectral compensation difference is 12db, the spectral compensation increment may be 1 db.

As can be seen, the spectrum compensation increment across resource slices is calculated based on the number of resource slices between a first resource slice in the first resource block and a second resource slice in the second resource block, so that the step size between resource slices can be determined, and the accurate spectrum compensation value of each resource slice can be determined subsequently.

Step 303, determining a spectrum compensation value of each resource slice between the first resource slice and the second resource slice based on the first spectrum compensation value and the spectrum compensation increment.

Wherein, for each resource slice, the following steps can be executed: calculating a spectral compensation value for the resource slice based on the first spectral compensation value, the spectral compensation delta, and an offset value for the resource slice relative to the first resource slice. For example, the offset value of the first resource slice after the first resource slice may be 1, the offset value of the second resource slice after the first resource slice may be 2, the spectrum compensation value of the first resource slice after the first resource slice may be obtained by adding the spectrum compensation increment once on the basis of the first spectrum compensation value, and the spectrum compensation value of the second resource slice after the first resource slice may be obtained by adding the spectrum compensation increment twice on the basis of the first spectrum compensation value, and so on, which is not described herein again.

Therefore, the efficiency and the performance of signal compensation can be greatly improved by the method.

Next, another signal compensation method in the embodiment of the present application is described with reference to fig. 4, where fig. 4 is a schematic flow chart of another signal compensation method provided in the embodiment of the present application, and is used for compensating a frequency spectrum of a resource block, and specifically includes the following steps:

step 401, a first spectral compensation value for a first resource block and a second spectral compensation value for a second resource block are determined.

Step 402, calculating a spectrum compensation increment across resource slices based on the number of resource slices between a first resource slice in the first resource block and a second resource slice in the second resource block.

Step 403, determining a spectrum compensation value of each resource slice between the first resource slice and the second resource slice based on the first spectrum compensation value and the spectrum compensation increment.

Step 404, determining a fitting compensation sum based on the first spectrum compensation value, the second spectrum compensation value and the spectrum compensation value of each resource slice.

Step 405, determining the sum of the actual spectrum offsets of the first resource slice, the second resource slice and each resource slice.

Wherein the sum of the actual spectral compensation can be determined by taking actual measurements for each resource slice.

Step 406, determining whether an error value between the fitting compensation sum and the actual compensation sum meets a preset error threshold.

When the error value does not meet the preset error threshold, step 407 is executed; when the error value meets the preset error threshold, step 408 is executed.

Step 407, reselecting the first resource slice and/or the second resource slice such that the number of resource slices between the first resource slice and the second resource slice is reduced to a first number.

For example, if the current number of resource slices between the first resource slice and the second resource slice is 24, the first resource slice and/or the second resource slice may be reselected so that the number of resource slices therebetween is 12.

Therefore, when the error of the fitting compensation value is large, the interpolation interval can be reduced, and the accuracy of the determined fitting compensation is improved.

Step 408, reselecting the first resource slice and/or the second resource slice such that the number of resource slices between the first resource slice and the second resource slice is increased to a second number.

Therefore, when the fitted compensation value is within the error range, the interpolation interval can be further expanded, and the efficiency of signal compensation is improved.

In a possible embodiment, when the error value meets the preset error threshold, the number of resource slices between the first resource slice and the second resource slice is determined to be an initial resource slice number, and the initial resource slice number is used to indicate the number of resource slices between the first resource slice and/or the second resource slice when the first resource slice and/or the second resource slice is reselected. Therefore, when signal compensation is performed next time, the initial resource piece quantity is directly called to select the first resource piece and the second resource piece, the quantity of the resource pieces spaced between the first resource piece and the second resource piece does not need to be considered, and the efficiency and the performance of the signal compensation are improved.

For convenience of understanding, the following describes, with reference to fig. 5, an exemplary method for signal compensation in an embodiment of the present application, where fig. 5 is a schematic flow chart of another method for signal compensation provided in the embodiment of the present application, and specifically includes the following steps:

step 501, determining M +1 target resource blocks according to the total number N of the resource blocks and the gain calculation interval X.

Wherein the gain calculation interval X represents the number of resource blocks at intervals between resource blocks requiring gain calculation, the target resource block represents the resource block requiring gain calculation, N is a positive integer greater than 1, X is a natural number less than or equal to N-1, and M is equal to or greater than

Meaning rounding up, it is understood that the gain calculation here is to be understood as the calculation of the spectral compensation value.

The total number N of resource blocks may be determined according to the bandwidth of the current communication system, for example, the bandwidth of 20MHz includes 100 resource blocks, and the bandwidth of 10MHz includes 50 resource blocks.

The gain calculation interval X may be determined from a preset database, which is not described herein in detail.

When determining the target resource block, the method may start with a first resource block, that is, the first resource block is a first target resource block, the number of resource blocks spaced between a second target resource block and the first target resource block is X, and similarly, the number of resource blocks spaced between an M +1 th target resource block and an M th target resource block is X.

It should be noted that the M +1 th target resource block is virtual in nature, and the M +1 th target resource block needs to be determined in order to determine the gain of the M-th target resource block that actually exists.

For example, when there are 19 resource blocks, if the gain calculation interval is 0, that is, N is 19 and X is 0, then M is equal to 19, it may be determined that all of the 19 resource blocks are target resource blocks, and it is also necessary to determine a 20 th target resource block, where the 20 th target resource block is a virtual resource block, and the number of resource blocks spaced from the 19 th target resource block is 0; and if the gain calculation interval is 2, i.e., N is 19 and X is 2, then M is equal to

After rounding up, M is equal to 7, it can be determined that the first resource block, the fourth resource block, the seventh resource block, the tenth resource block, the thirteenth resource block, the sixteenth resource block, and the nineteenth resource block of the 19 resource blocks are the first 7 target resource blocks, and it is also necessary to determine that the virtual twenty-second resource block is the 8 th target resource block. And so on, and will not be described herein.

It will be appreciated that the size of the gain calculation interval is proportional to the speed of the subsequent frequency domain compensation and inversely proportional to the accuracy of the frequency domain compensation. The gain calculation interval is the maximum interval at which the final signal compensation result is smaller than the error range, and an inaccurate signal compensation result may be obtained by increasing the resource block interval.

Therefore, the M +1 target resource blocks are determined according to the total number N of the resource blocks and the gain calculation interval X, so that the signal compensation performance can be ensured as much as possible, and the signal compensation efficiency can be improved.

Step 502, calculating the gain of the first resource slice of each target resource block to obtain M +1 first gains.

In the frequency domain, one target resource block may include 12 resource slices, each target resource block is continuous in the frequency domain, and each resource slice is also continuous in the frequency domain, so that the gain of the first resource slice of each target resource block may be preferentially calculated to obtain M +1 first gains, and each first gain corresponds to each target resource block.

The gain of the first resource slice of each target resource block may be determined according to a preset fitting order, a sampling rate, and a resource slice interval, so as to obtain the M +1 first gains, where the resource slice interval represents the number of resource slices between a first resource slice of any one target resource block except the first target resource block and a first resource slice of the first target resource block, that is, the number of resource slices between the first resource slice and the second resource slice.

Specifically, the preset fitting order represents an order of data fitting, and in brief, the higher the order of fitting is, the more accurate the data obtained by final fitting is, and the preset fitting order may be set as needed, which is not described herein.

Specifically, the resource slice interval of the first resource slice of the first target resource block may be set to 0, when the total number of resource blocks is an even number, no dc subcarrier exists, the number of resource slices between the first resource slice of the second target resource block and the first resource slice of the first target resource block is 12, the number of resource slices between the first resource slice of the third target resource block and the first resource slice of the first target resource block is 24, and so on, the resource slice interval of each target resource block may be obtained. When the total number of the resource blocks is odd, a direct current subcarrier exists, and because the direct current subcarrier only exists in the resource block at the middle, one may be added to the resource block interval of the target resource block after the direct current subcarrier, for example, there are three resource blocks now, and the three resource blocks are all target resource blocks, then the direct current subcarrier may exist on the second resource block, then the number of resource blocks between the first resource block of the second target resource block and the first resource block of the first target resource block is 12, the number of resource blocks between the first resource block of the third target resource block and the first resource block of the first target resource block is 25, and so on, and the description is omitted here.

In one possible embodiment, i represents the resource slice spacing, a _z The fitting parameter is represented, z represents a preset fitting order, the maximum value of the preset fitting order is Z, fs representing the sampling rate, 15KHZ represents the length of one resource slice, and the Gain can be calculated by the following formula:

as can be seen, with the first resource slice of the first target resource block as a reference, the gains of the first resource slices of other target resource blocks relative to the first resource slice of the first resource block can be determined, and M +1 first gains are obtained.

The M +1 first gains are obtained by calculating the gain of the first resource piece of each target resource block, so that fitting of the resource pieces between every two target resource blocks can be facilitated, the gain of each resource piece is determined under the condition that each resource piece is not measured, and the efficiency of signal compensation is greatly improved.

Step 503, determining a second gain of each remaining resource slice according to the gain difference of every two consecutive first gains.

Wherein the remaining resource slice represents a resource slice other than a first resource slice of each of the first M target resource blocks. For example, when the total number of resource blocks is N, the total number of resource slices is 12N, knowing the first gain of the first resource slice of M +1 target resource blocks, the number of remaining resource slices is 12N-M, and the second gains of 12N-M remaining resource slices can be determined according to the gain difference of every two consecutive first gains.

Specifically, M gain difference values may be determined according to the M +1 first gains, where the gain difference value represents a difference value between a first gain of a first resource slice of any one target resource block and a first gain of a first resource slice of a previous target resource block; then, determining M unit gain difference values of the first M target resource blocks according to the M gain difference values, wherein the M unit gain difference values correspond to the first M target resource blocks one to one; and finally, determining a second gain of each residual resource slice in the first M target resource blocks according to the first M first gains and the M unit gain difference values.

In a possible embodiment, when the total number N of resource blocks is an even number, each gain difference may be divided by a first unit resource slice number to obtain the M unit gain differences, where the first unit resource slice number represents a product of a resource slice number included in each resource block and (X + 1). Here, each resource block includes 12 resource pieces, and X is a gain calculation interval.

For convenience of understanding, the following description may refer to fig. 6A, where fig. 6A is a schematic diagram of a method for determining a unit gain difference without a dc subcarrier provided in this embodiment of the present application, where a horizontal axis of the schematic diagram is a frequency domain, and a vertical axis of the schematic diagram is a gain amplitude, and it is seen that, given that a gain calculation interval is 0, a target resource block RB1 includes 12 resource slices, which are RE0, RE1, RE2, RE3, RE4, RE5, RE6, RE7, RE8, RE9, RE10, and RE11, respectively. Now, knowing the first gain of RE0 of RB1 and the first gain of RE0 of the first resource slice of RB2, the gain difference between RB1 and RB2 can be calculated, and then dividing by 12 × 0+1, the unit gain difference of each resource slice in RB1 can be obtained, it can be understood that the second gain of RE1 in RB1 is the first gain of RE0 in RB1 plus the unit gain difference, the second gain of RE2 in RB1 is the second gain of RE1 in RB1 plus the unit gain difference, and so on, the respective second gains of RE1, RE2, RE3, RE4, RE5, RE6, RE7, RE8, RE9, RE10, and 11 can be obtained.

Here, RE0, RE1, and the like denote the number of resource pieces of the corresponding target resource block, and do not denote any specific designation of any resource piece.

Similarly, when calculating the second gain of each resource slice in RB2, it needs to be determined by dividing the gain difference between RB2 and RB3 by 12, and will not be described herein again.

Fig. 6A shows a case where the gain calculation interval is 0, and the following description shows a case where the gain calculation interval is 1 in conjunction with fig. 6B, which are easier to understand by comparison. Fig. 6B is a schematic diagram of another method for determining a unit gain difference without dc subcarriers according to the embodiment of the present application, where the horizontal axis of the diagram is a frequency domain, and the vertical axis is a gain amplitude, it can be seen that a known gain calculation interval is 1, a target resource block RB1 includes 12 resource slices, at this time, the target resource blocks are RB1 and RB3, and RB1 and RB3 are separated by one resource block RB2, the RB2 also includes 12 resource slices, knowing a first gain of a first resource slice of RB1 and a first gain of a first resource slice of RB3, a gain difference between RB1 and RB3 may be determined first, then the gain difference is divided by 12 × RB (1+1) to obtain a unit gain difference between RB1 to RB3, and then the unit gain differences are sequentially accumulated to obtain a second gain of remaining resource slices between RB1 and RB3, that is to say, a second gain of RE1 in RB1 is a first gain difference of RE1 plus the unit gain 0, the second gain for RE2 in RB1 is the second gain for RE1 in RB1 plus the unity gain difference, and so on, for each remaining resource slice between RB1 and RB 3.

In a possible embodiment, when the total number N of resource blocks is an odd number, a special gain difference value of the M gain difference values may be determined, where the special gain difference value represents a gain difference value corresponding to two consecutive target resource blocks including the (N/2) +1 st resource block; then, dividing the special gain difference by a second unit resource slice number to obtain a special unit gain difference, and dividing M-1 gain differences except the special gain difference by a first unit resource slice number to obtain M-1 unit gain differences, wherein the first unit resource slice number represents the product of the resource slice number included in each resource block and (X +1), and the second unit resource slice number is equal to the first unit resource slice number plus one.

For convenience of understanding, the following method for calculating the unit gain difference of the target resource block of the DC subcarrier is illustrated, and referring to fig. 6C, fig. 6C is a schematic diagram of a method for determining the specific unit gain difference of the DC subcarrier provided in this embodiment, where the horizontal axis of the diagram is a frequency domain and the vertical axis of the diagram is a gain amplitude, it can be seen that the known gain calculation interval is 0, and the target resource block RB1 includes 12 resource blocks, i.e., RE0, RE1, RE2, RE3, RE4, RE5, RE6, RE7, RE8, RE9, RE10, and RE11, where the DC subcarrier is located between RE5 and RE 6. Now, knowing the first gain of RE1 of RB1 and the first gain of RE1 of RB1, a special gain difference between RB1 and RB1 can be calculated, and then dividing by 13 × (0+1) can obtain a unit gain difference of each resource slice in RB1, it can be understood that the second gain of RE1 in RB1 is the first gain of RE1 in RB1 plus the unit gain difference, the second gain of RE1 in RB1 is the second gain of RE1 in RB1 plus the unit gain difference, and since RE1 and RE1 in RB1 span two subcarriers, the second gain of RE1 in RB1 is the second gain of RE1 in RB1 plus twice the unit gain difference, and so on, the respective second gains of RE1, and RE1 can be obtained. And will not be described in detail herein.

It should be noted that, only when two consecutive target resource blocks include the (N/2) +1 st resource block and the total number N of the resource blocks is an odd number, the previous target resource block of the two consecutive target resource blocks needs to be divided by the first unit resource piece number plus one when calculating the unit gain difference, and the target resource blocks other than the previous target resource block of the two consecutive target resource blocks still divide by the first unit resource piece number when calculating the unit gain difference.

Therefore, the second gain of each remaining resource slice is determined according to the gain difference value of every two continuous first gains, and the second gain of each remaining resource slice can be determined by a linear interpolation method, so that the accuracy of the gain is ensured, and the processing efficiency is improved.

And step 504, determining a compensation coefficient of each resource slice according to each first gain and each second gain.

The M first compensation coefficients of the first resource slice of the first M target resource blocks may be determined according to the first M first gains, and the second compensation coefficient of each remaining resource slice may be determined according to the second gain of each remaining resource slice.

And 505, compensating the radio frequency signal according to the compensation coefficient of each resource slice to obtain a compensated radio frequency signal.

The radio frequency signal can be compensated based on the first compensation coefficient and the second compensation coefficient, so as to obtain a compensated radio frequency signal.

For frequency domain compensation of the rf signal, reference may be made to the existing compensation method, which is not described herein.

It can be seen that, by the above signal compensation method, firstly, M +1 target resource blocks are determined according to the total number N of resource blocks and a gain calculation interval X, where the gain calculation interval X represents the number of resource blocks that need to be subjected to a gain calculation, the target resource blocks represent the resource blocks that need to be subjected to a gain calculation, N is a positive integer greater than 1, X is a natural number less than or equal to N-1, and M is equal to or less than N-1

Then, calculating the gain of the first resource piece of each target resource block to obtain M +1 first gains; then, determining a second gain of each remaining resource slice according to a gain difference value of every two continuous first gains, wherein the remaining resource slices represent resource slices except the first resource slice of each target resource block in the first M target resource blocks; then, determining a compensation coefficient of each resource slice according to each first gain and each second gain; and finally, compensating the radio frequency signal according to the compensation coefficient of each resource slice to obtain a compensated radio frequency signal. The efficiency and performance of signal compensation can be greatly improved.

Next, another signal compensation method in the embodiment of the present application is described with reference to fig. 7, where fig. 7 is a schematic flow chart of another signal compensation method provided in the embodiment of the present application, and specifically includes the following steps:

step 701, determining c +1 resource blocks to be calculated according to the total number a of the pre-estimated resource blocks and the first pre-estimated calculation interval b 1.

The first pre-estimation calculation interval b1 represents the number of pre-estimation resource blocks at intervals between pre-estimation resource blocks requiring gain calculation, and the resource block to be calculated represents the pre-estimation resource requiring gain calculationA source block, a is a positive integer greater than 1, b1 is a natural number less than or equal to a-1, c is equal to

Indicating rounding up.

Here, the step of determining resource blocks to be calculated may refer to the description of step 301 in fig. 3, and is not described herein again.

Step 702, determining the fitting gain of each resource slice in the c +1 resource blocks to be calculated, and obtaining the sum of the fitting gains.

The gain of the first resource slice of each resource block to be calculated may be calculated first, the fitting gain of each resource slice is determined with reference to the descriptions in step 502 and step 503, and the fitting gains of all resource slices are summed to obtain the sum of the fitting gains.

And 703, determining the actual gain of each resource slice in the c +1 resource blocks to be calculated to obtain the sum of the actual gains.

The gain calculation formula in step 502 may be applied to each resource slice to obtain the actual gain of each resource slice, and the actual gains of all resource slices are summed to obtain the sum of the actual gains.

Step 704, determining whether an error value between the sum of the actual gains and the sum of the fitting gains meets a preset error threshold.

Wherein, when the error value does not meet the preset error threshold, step 705 is executed; when the error value meets the preset error threshold, step 706 is executed.

Step 705, when the error value does not meet the preset error threshold, determining a second pre-estimated calculation interval b2 as the gain calculation interval.

Wherein b2 is equal to b 1-1. It will be appreciated that the size of the gain calculation interval is proportional to the speed of the subsequent frequency domain compensation and inversely proportional to the accuracy of the frequency domain compensation. A value may be decreased to obtain a gain calculation interval.

In one possible embodiment, the gain calculation interval may be stored in an initial database and may be directly recalled when signal compensation is actually required. The efficiency of signal compensation is improved while the performance of signal compensation is ensured as much as possible.

In step 706, when the error value meets the preset error threshold, a third pre-estimated calculation interval b3 is determined.

Wherein b3 equals b1+ 1.

And 707, determining d +1 resource blocks to be calculated according to the total number a of the pre-estimated resource blocks and the third pre-estimated calculation interval b 3.

Wherein d is equal to

Is rounded up.

Step 708, determining the fitting gain of each resource slice in the d +1 resource blocks to be calculated, and obtaining the sum of the fitting gains.

And 709, determining the actual gain of each resource slice in the c +1 resource blocks to be calculated to obtain the sum of the actual gains.

Step 710, determining whether an error value between the sum of the actual gains and the sum of the fitting gains meets the preset error threshold.

Step 711, when the error value does not meet the preset error threshold, determining a fourth pre-estimated calculation interval b4 as the gain calculation interval.

Wherein b4 is equal to b 3-1.

It can be seen that steps 707-711 are actually a loop of steps 701-705.

And 712, determining M +1 target resource blocks according to the total number N of the resource blocks and the gain calculation interval X.

Step 713, calculating the gain of the first resource slice of each target resource block to obtain M +1 first gains.

In step 714, a second gain of each remaining resource slice is determined according to a gain difference of each two consecutive first gains.

And 715, determining a compensation coefficient of each resource slice according to each first gain and each second gain.

And 716, compensating the radio frequency signal according to the compensation coefficient of each resource slice to obtain a compensated radio frequency signal.

The steps not described in detail above can be referred to the description of all or part of the method in fig. 5, and are not described again here.

Therefore, by the signal compensation method, the efficiency of signal compensation can be improved while the performance of signal compensation is ensured as much as possible.

The efficiency and performance of signal compensation can be greatly improved.
