Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The following will describe in detail a method and an apparatus for detecting a time slot number of an LTE uplink shared channel and a non-signaling comprehensive tester according to embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a flowchart of an LTE uplink shared channel timeslot number detection method according to an embodiment of the present application. The LTE uplink shared channel slot number detection method of fig. 1 may be performed by a non-signaling comprehensive tester. As shown in fig. 1, the method for detecting the time slot number of the LTE uplink shared channel includes:
step S101, randomly selecting a piece of data to be detected with a length of at least 2 milliseconds from an LTE uplink shared channel, and determining a first DMRS boundary of a first time slot position of the data to be detected and a second DMRS boundary of a second time slot position of the data to be detected based on the correlation characteristic of a cyclic prefix of an OFDM symbol.
The length of the data to be measured is at least 2ms (milliseconds), and for example, may be 2ms, 3ms, 4ms, or the like.
The first time slot data of the first time slot position and the second time slot data of the second time slot position are all 0.5ms in length.
Referring to fig. 2, as an example, assuming that the data to be measured is data with a length of l=2 ms randomly selected from the LTE uplink shared channel, the data to be measured includes a first slot position (1), a second slot position (2), a third slot position (3), and a fourth slot position (4), where the first slot position (1) corresponds to the first slot data (1), the second slot position (2) corresponds to the second slot data (2), the third slot position (3) corresponds to the third slot data (3), and the fourth slot position (4) corresponds to the fourth slot data (4).
Each slot of LTE consists of a certain number of OFDM symbols including a Cyclic Prefix (CP). If the system is of Normal CP type (Normal CP type), each slot includes 7 OFDM symbols; if the Extended CP type (Extended CP type), each slot includes 6 OFDM symbols. The cyclic prefix is typically a tail repeated sequence of OFDM symbols.
With continued reference to fig. 2, taking the first slot data (1) as an example, the symbol boundary of each OFDM symbol may be calculated according to the characteristic of the autocorrelation of the CP position data of each OFDM symbol in the first slot data. Assuming that the system is of a normal CP type, the first slot data includes 7 OFDM symbols, and symbol boundaries of the 7 OFDM symbols (0 to 6 th OFDM symbols) can be calculated in the above manner.
Referring to fig. 3, in general, one slot contains 1 DMRS symbol, and the DMRS symbol is generally mapped to the 4 th OFDM symbol of the slot. The starting position of the DMRS symbol in each slot (i.e., DMRS boundary, DMRS-related peak position) may be slightly deviated, which is typically around ±0.5 OFDM symbols, due to resource scheduling and the like.
Since 1 time slot has only 1 DMRS symbol, a DMRS correlation peak can be obtained after sliding correlation is performed on the data of one time slot, and the DMRS correlation peak position of the DMRS correlation peak can be further determined.
It can be appreciated that the first DMRS boundary, i.e., the starting position of the DMRS symbol that is the first slot position of the data to be measured, can be denoted as timingRef1. The second DMRS boundary, i.e., the starting position of the DMRS symbol that is the second slot position of the data to be measured, may be denoted as timingRef2.
Step S102, determining the position of a DMRS correlation peak under each time slot number configuration of the LTE data frame.
The LTE data frame can be a data frame in an LTE-FDD format or a data frame in an LTE-TDD format.
Referring to fig. 4, taking an LTE data frame as an example of a data frame in LTE-FDD format, the LTE data frame includes 20 slot number configurations, one slot number configuration corresponds to one slot number, the slot numbers are #0 to #19, two slots form a subframe, the length of each subframe is 1ms, and the length of each slot is 0.5ms. According to the obtained cell ID configuration information and RB (Resource Block) configuration information, the DMRS correlation peak positions corresponding to each of the slot numbers #0 to #19 are respectively determined, and are respectively recorded as time 1 to time 20, wherein time 1 is the DMRS correlation peak position of the slot number #0, time 2 is the DMRS correlation peak position of the slot number # 1.
Step S103, determining correct time slot number configuration information of the data to be tested according to the first DMRS boundary, the second DMRS boundary and the positions of the related peaks of the DMRS under the configuration of each time slot number.
According to the technical scheme provided by the embodiment of the application, the correct time slot number configuration information of the data to be detected can be automatically detected based on the correlation characteristic of the Cyclic Prefix (CP) of the OFDM symbol and the correlation characteristic between the DMRS correlation peaks, and the accuracy is higher. Specifically, a first DMRS boundary of a first time slot position of the data to be detected and a second DMRS boundary of a second time slot position of the data to be detected are determined based on the correlation characteristic of a cyclic prefix of an OFDM symbol by randomly selecting data to be detected with a length of at least 2 milliseconds from an LTE uplink shared channel; determining the position of a DMRS correlation peak under each time slot number configuration of an LTE data frame; according to the first DMRS boundary, the second DMRS boundary and the positions of the related peaks of the DMRS under the configuration of each time slot number, the correct time slot number configuration information of the data to be tested is determined, and the accuracy of detecting the time slot number of the LTE uplink shared channel of the non-signaling comprehensive tester can be effectively improved.
In some embodiments, referring to fig. 4, when the LTE data frame is a data frame in LTE-FDD format, one LTE-FDD format data frame includes 20 slot number configurations (i.e., 20 slots), one slot number configuration corresponds to one slot number, which is #0 to #19 respectively, and one slot number configuration includes one DMRS correlation peak position. Referring to fig. 5, when the LTE data frame is a data frame in LTE-TDD format, the data frame has a length of 10ms and is composed of two half frames having a length of 5ms, and each half frame is composed of five subframes having a length of 1 ms. For example, the first half frame is composed of subframes #0 to #4, and the second half frame is composed of subframes #5 to # 9. Each subframe consists of two slots of length 0.5 ms. I.e. one LTE-TDD formatted data frame also comprises 20 slots (20 slot number configuration).
The step of determining correct time slot number configuration information of the data to be tested according to the first DMRS boundary, the second DMRS boundary and the positions of the related peaks of the DMRS under the configuration of each time slot number comprises the following steps:
calculating the difference between the first DMRS boundary of the first time slot data and the positions of the related peaks of the DMRS under the configuration of each time slot number to obtain a first comparison result;
calculating a difference value between a second DMRS boundary of the second time slot data and the positions of the related peaks of the DMRS under the configuration of each time slot number to obtain a second comparison result;
and determining correct time slot number configuration information of the data to be tested according to the first comparison result and the second comparison result.
As an example, assume that the LTE data frame is a data frame in LTE-FDD format, and the length of the data to be measured is 2 ms, including 4 slot positions, which are a first slot position (1), a second slot position (2), a third slot position (3), and a fourth slot position (4), respectively, where the first slot position (1) corresponds to the first slot data, the second slot position (2) corresponds to the second slot data, the third slot position (3) corresponds to the third slot data, and the fourth slot position (4) corresponds to the fourth slot data.
And respectively calculating differences S1-S20 between the first DMRS boundary timingRef1 of the first time slot data and the DMRS correlation peak positions timing1-timing20 corresponding to 20 time slots in the LTE data frame, and obtaining a first comparison result. Wherein S1 represents the difference between timingRef1 and time 1 (i.e., the position offset value between the first DMRS boundary of the first slot data and the DMRS correlation peak position of slot # 0); s2 represents the difference between timingRef1 and timing2.
And respectively calculating difference values Y1-Y20 between the second DMRS boundary timingRef2 of the second time slot data and the DMRS correlation peak positions timming 1-timming 20 corresponding to the 20 time slots, and obtaining a second comparison result. Wherein Y1 represents the difference between timingRef2 and timming 1, Y2 represents the difference between timingRef2 and timming 2.
Then, according to the first comparison result and the second comparison result, determining the correct time slot number configuration information of the data to be tested, specifically including: determining first time slot number configuration information of data to be tested according to a first comparison result, wherein the first time slot number configuration information is a group of time slot number configurations and comprises 1 to a plurality of time slot number configurations; determining second time slot number configuration information of the data to be tested according to a second comparison result, wherein the second time slot number configuration information is a group of time slot number configurations and comprises 1 to a plurality of time slot number configurations; and determining correct time slot number configuration information of the data to be tested according to the first time slot number configuration information and the second time slot number configuration information.
As an example, according to the first comparison result, the first timeslot number configuration information of the data to be measured is determined, specifically, the magnitudes of the difference values S1 to S20 may be compared, and the timeslot number of the timeslot corresponding to the minimum value therein is determined as the first timeslot number of the first timeslot position of the data to be measured. After the first time slot number of the first time slot position of the data to be measured is determined, the time slot numbers of the second time slot position, the third time slot position and the like of the data to be measured are forward based on the first time slot number, and the configuration information of the first time slot number of the data to be measured can be obtained. For example, according to the comparison, the difference S3 is the smallest, and the time slot number of the time slot corresponding to the difference S3 is #2, then it may be determined that the first time slot number of the first time slot position of the data to be measured is #2, the second time slot number of the second time slot position of the data to be measured is #3, and the third time slot number of the third time slot position is #4. According to the total length of the data to be measured, the number of the time slots can be calculated, after the first time slot number of the first time slot position of the data to be measured is determined, the first time slot number is followed on the basis of the first time slot number, and then the complete first time slot number configuration information of the data to be measured can be obtained. For example, the total length of the data to be measured is 2 ms, including 4 time slots, and the first time slot number of the first time slot position (1) of the data to be measured is determined to be #2 according to the first comparison result, then the first time slot number configuration information is: #2 (first time slot data corresponding to the first time slot position (1)), #3 (second time slot data corresponding to the second time slot position (2)), and #4 (third time slot data corresponding to the third time slot position (3)).
Similarly, the second timeslot number configuration information of the data to be tested can be determined by referring to the determination manner of the first timeslot number configuration information, which is not described herein in detail.
In some embodiments, determining correct timeslot number configuration information of the data to be tested according to the first timeslot number configuration information and the second timeslot number configuration information includes:
if the time slot number configuration information of the data to be tested obtained according to the first time slot number configuration information and the second time slot number configuration information is unique, determining the first time slot number configuration information or the second time slot number configuration information as correct time slot number configuration information of the data to be tested;
if the time slot number configuration information of the data to be measured obtained according to the first time slot number configuration information and the second time slot number configuration information is not unique, continuing to determine a third DMRS boundary of a third time slot position of the data to be measured;
and determining correct time slot number configuration information of the data to be tested according to the third DMRS boundary and the positions of the related peaks of the DMRS under the configuration of each time slot number.
For ease of understanding, continuing with the above example, assume that the first slot number configuration information and the second slot number configuration information are both #2, #3, #4, #5; then the correct slot number configuration information for the data under test can be determined to be #2, #3, #4, #5.
Assuming that the time slot number configuration information of the to-be-measured data obtained according to the first time slot number configuration information and the second time slot number configuration information is not unique, continuously determining a third DMRS boundary of third time slot data of a third time slot position of the to-be-measured data according to the method; then, calculating a difference value between a third DMRS boundary of third time slot data and a DMRS related peak position under each time slot number configuration to obtain a third comparison result, and determining third time slot number configuration information of the data to be tested according to the third comparison result; if the time slot number configuration information of the data to be tested determined according to the third time slot number configuration information is not unique with the time slot number configuration information of the data to be tested determined according to the first time slot number configuration information or the second time slot number configuration information, the first time slot number configuration information is determined to be the correct time slot number configuration information of the data to be tested.
For example, the length of the data to be measured is 2ms, 4 time slots are shared, the first time slot number configuration information and the second time slot number configuration information obtained according to the method are inconsistent, the time slot number configuration information of the data to be measured determined according to the third time slot number configuration information is not unique with the time slot number configuration information of the data to be measured determined according to the first time slot number configuration information or the second time slot number configuration information, and at the moment, the first time slot number configuration information is determined to be the correct time slot number configuration information of the data to be measured.
In general, the calculation results of the first two time slots (i.e., one subframe) of the data to be measured are synthesized, so that one or more groups of slot estimation values with minimum offset can be obtained, and for the calculation results of the current two time slots, a group of results can be arbitrarily taken to determine the correct time slot number configuration information of the data to be measured.
If the requirement of continuously measuring a plurality of time slot data is met, the detection result is unique, the time slot data of the next time slot position (such as the third time slot position) of the data to be measured can be selected in the total time slot number range of the data to be measured to continue detection so as to be converged to the unique, and finally, the correct time slot number configuration information of the data to be measured is determined.
According to the technical scheme provided by the embodiment of the application, the difference value between the DMRS boundary of the time slot data of the front and rear adjacent two time slot positions in the data to be detected and the corresponding DMRS correlation peak positions of 20 time slots is combined, one or more groups of slot (time slot) estimated values with the minimum offset are obtained based on the difference value, the correct time slot number configuration information of the data to be detected is further determined, the false detection rate and the non-detection probability can be reduced, and the accuracy of automatically detecting the time slot number of the data to be detected in the LTE uplink shared channel based on the non-signaling comprehensive tester is effectively improved.
In some embodiments, determining correct time slot number configuration information of the data to be measured according to the first DMRS boundary, the second DMRS boundary, and the DMRS correlation peak positions under each time slot number configuration includes:
dividing the same time slot number of the DMRS sequences in the 20 time slot number configurations of the LTE data frame into the same group to obtain N DMRS feature sets under the grouping time slot number configuration, wherein each DMRS feature set comprises at least one DMRS related peak position of the time slot number, the DMRS related peak positions of the time slot numbers in the same DMRS feature set are the same, and N is an integer of 4-10;
determining the positions of the DMRS related peaks of the packets corresponding to each DMRS feature set to obtain the positions of the DMRS related peaks under the configuration of N packet time slot numbers;
and determining correct time slot number configuration information of the data to be tested according to the first DMRS boundary, the second DMRS boundary and the positions of the related peaks of the DMRS under the N grouping time slot number configurations.
The following description will take an LTE data frame as an example of an LTE-TDD format data frame. For given cell ID configuration information and RB (resource block) configuration information, a fixed DMRS feature sequence is obtained, and generally, the DMRS feature values of 20 slots include 4 to 10 different values, and according to the different values of the DMRS feature values, the DMRS correlation peak positions of 20 slots of the LTE data frame can be divided into DMRS feature sets under N grouping slot number configuration, where the value of N is an integer of 4 to 10. For the same characteristics of the DMRS sequences corresponding to some time slot number configurations in the 20 optional time slot number configurations, the time slot numbers with the same DMRS sequences can be divided into the same group, so that the 20 time slot number configurations are divided into N groups according to the characteristics of the DMRS sequences, and the value range of N is 4-10.
DMRS sequences under different slot number configurations may be characterized by using phase eigenvalues RsNcs corresponding to the different slot number configurations. In one embodiment, the phase eigenvalues RsNcs0 to RsNcs19 configured for the time slot data corresponding to the time slot numbers #0 to #19 can be extracted in advance; then, the same slot number and slot data of the phase eigenvalue RsNcs are divided into the same phase eigenvalue set. For example, the phase eigenvalues of slot numbers #0, #5(corresponding to RsNcs 0) and +.>If (corresponding to RsNcs 19) is the same, then the time slot numbers #0, #5 and their corresponding phase eigenvalues, time slot data can be divided into the same phase eigenvalue set, denoted as phase eigenvalue set A1->. Similarly, for the phase eigenvalues of other time slot numbers, the same method can be adopted to determine the phase eigenvalue set to which the phase eigenvalue belongs.
As an example, assume that according to the above method, the phase eigenvalues corresponding to 20 slot numbers #0 to #19 are divided into the following 4 sets of phase eigenvalues, which are respectively:
A1
A2
A3
A4
according to the phase characteristic value sets A1-A4, corresponding 4 DMRS characteristic sets B1-B4 can be obtained. For example, the phase eigenvalue set A1Corresponding DMRS feature set B1 is B1。/>Can pass- >To characterize.
In some embodiments, for each phase eigenvalue set, one time slot can be randomly selected as a target time slot; determining the position of a target DMRS related peak corresponding to the target time slot according to the target phase characteristic value corresponding to the target time slot; and determining other DMRS related peak positions of other time slots except the target time slot in the phase characteristic value set according to the target DMRS related peak position, and obtaining the grouping DMRS related peak position corresponding to the phase characteristic value set.
Since the DMRS correlation peak positions corresponding to the respective phase eigenvalues in the same phase eigenvalue set are the same, the DMRS correlation peak positions corresponding to the phase eigenvalues corresponding to the other time slots in the same phase eigenvalue set can be determined as long as the DMRS correlation peak positions corresponding to the phase eigenvalue corresponding to any one time slot in the same phase eigenvalue set are determined. Taking the phase eigenvalue set A1 as an example, the time slot can be randomly selectedAs a target time slot, according to the time slot->Target phase characteristic value +.>Determining the corresponding purposeMarking the position of the related peak of the DMRS as timing 0 The method comprises the steps of carrying out a first treatment on the surface of the Thereafter, according to timing 0 Other DMRS correlation peak positions of other slots (i.e., instant # 5) in the full phase eigenvalue set A1 can be quickly filled, noted as timing 5 Wherein, time 0 With timing 5 And consistent.
The 20 phase characteristic values are divided into N phase characteristic value sets, any one of the phase characteristic value sets is randomly selected as a target time slot, the target DMRS related peak position of the target time slot is calculated according to the target phase characteristic value of the target time slot, and then the DMRS related peak positions of other time slots in the complete same phase characteristic value set can be rapidly filled in a copying mode, so that the grouped DMRS related peak positions corresponding to the phase characteristic value sets can be obtained, the operation rate of the DMRS related peak positions corresponding to the time slots can be improved, and the automatic detection rate of the time slot number of the data to be detected can be improved.
In some embodiments, determining correct slot number configuration information of the data to be measured according to the first DMRS boundary, the second DMRS boundary, and the DMRS correlation peak positions under the N packet slot number configurations includes:
calculating the difference between the first DMRS boundary of the first time slot data and the packet DMRS correlation peak position corresponding to each DMRS feature set to obtain N first packet comparison results;
calculating the difference between the second DMRS boundary and the packet DMRS correlation peak position of each DMRS feature set to obtain N second packet comparison results;
And determining the correct time slot number configuration information of the data to be tested according to the N first packet comparison results and the N second packet comparison results.
For the sake of illustration, continuing with the above example, referring to fig. 2, the data to be measured includes four slot positions, namely, a first slot position (1), a second slot position (2), a third slot position (3) and a fourth slot position (4). First, a first DMRS boundary timingRef1 of first time slot data and each of them are calculated respectivelyAnd obtaining 4 first packet comparison results by the difference value between the difference values between the corresponding packet DMRS correlation peak positions of the DMRS feature sets B1-B4. For example, taking the example of calculating the difference between the first DMRS boundary timingRef1 and the packet DMRS correlation peak position of the DMRS feature set B1, the target DMRS correlation peak position timing corresponding to the #0 slot in the first DMRS boundary timingRef1 and the DMRS feature set B1 may be calculated 0 The difference value between the two results is obtained to obtain a first grouping comparison result a1Wherein sym0 represents timingRef1 and timming 0 Difference between sym0=sym5. Similarly, the difference between the first DMRS boundary timingRef1 and the DMRS feature sets B2, B3, B4 may be calculated.
Similarly, the difference between the second DMRS boundary timingRef2 of the second time slot data and the DMRS feature sets B1, B2, B3, and B4 can be calculated by referring to the above method, and will not be described herein.

if the time slot number configuration information obtained according to the fourth time slot number configuration information and the fifth time slot number configuration information is unique, determining correct time slot number configuration information of the data to be tested according to the time slot number corresponding to the time slot in the first target set.
For ease of understanding, continuing with the example above, assume that the 4 first packet comparison results calculated according to the steps above are:
a1
a2
a3
a4
since the differences corresponding to the time slots in the same first packet comparison result are the same, the difference corresponding to any one time slot in the same first packet comparison result can be arbitrarily selected to represent the difference of the first packet comparison result, and then the DMRS feature set with the smallest difference is selected to be determined as the first target set by comparing the differences of the first packet comparison results. And finally, determining fourth time slot number configuration information of the data to be tested according to the time slot number in the first target set. Illustratively, assuming that the DMRS feature set with the smallest difference from the first DMRS boundary timingRef1 is B1, determining the DMRS feature set as B1 as the first target set; and the DMRS feature set is that the timeslot numbers in B1 include #0 and #5, and according to the timeslot number #0 therein, it can be determined that the first timeslot number configuration information of the data to be measured is: #0 (first time slot data corresponding to the first time slot position (1)), #1 (second time slot data corresponding to the second time slot position (2)), #2 (third time slot data corresponding to the third time slot position (3)), and #3 (fourth time slot data corresponding to the fourth time slot position (4); or is: #5 (first slot data corresponding to the first slot position (1)), #6 (second slot data corresponding to the second slot position (2)), #7 (third slot data corresponding to the third slot position (3)), and #8 (fourth slot data corresponding to the fourth slot position (4)).
Similarly, according to the above manner, the configuration information of the fifth timeslot number of the data to be tested may be determined according to the N second packet comparison results, which is not described herein.
And finally, comparing whether the fourth time slot number configuration information is consistent with the fifth time slot number configuration information, and if so, determining the fourth time slot number configuration information or the fifth time slot number configuration information as correct time slot number configuration information of the data to be tested. For example, the fourth timeslot number configuration information and the fifth timeslot number configuration information are identical, and are #0 (corresponding to the first timeslot data of the first timeslot position (1)), #1 (corresponding to the second timeslot data of the second timeslot position (2)), #2 (corresponding to the third timeslot data of the third timeslot position (3)), and #3 (corresponding to the fourth timeslot data of the fourth timeslot position (4)), then the correct timeslot number configuration information of the data to be tested is: #0 (first slot data corresponding to the first slot position (1)), #1 (second slot data corresponding to the second slot position (2)), #2 (third slot data corresponding to the third slot position (3)), and #3 (fourth slot data corresponding to the fourth slot position (4)).
