Specific embodiment

At present, user terminal receive base station transmission the data comprising PSS after, first to the data PSS detections are carried out, then SSS detections are carried out to the data, such that it is able to the result detected according to SSS, Obtain the information of respective cell.Wherein, PSS detections are carried out to the data, will the data and sheet Ground PSS sequences make related operation, to produce multiple peak values.SSS detections, i.e. root are carried out to the data The peak value obtained according to PSS detections intercepts corresponding data, then the data that will be truncated to and local SSS sequences Make related operation, such that it is able to the result according to related operation and according to identical detection time, obtain phase The information of cell is answered, the detection process to adjacent cell is completed.

However, in above-mentioned adjacent cell detection process, after the data are detected through PSS, can produce more Peak value, therefore, when carrying out SSS according to the peak value and detecting, the calculating of SSS detection can be caused Amount is larger.Also, PSS detection produce peak value in, including the cell for having detected peak value, The peak value of the cell for detecting can produce interference to SSS detections, in causing SSS to detect obtained cell, False drop rate is higher.

Regarding to the issue above, The embodiment provides a kind of detection method of user terminal adjacent cell, Methods described after the data that will be received make related operation with local PSS sequences, by will correlation transport In the peak value that calculation is obtained, by peak value screen corresponding from the peak value of the different synchronic group cells for having detected interval Cover, and then can be according to the information of other synchronic group cells of the peakvalue's checking not shielded, further according to same The cell information detected in synchronic group detects other cell informations in the same synchronic group.Due to The interval corresponding peak value of the peak value of the different synchronic group cells for detecting has been shielded, therefore can be reduced and carried out The quantity of peak value during subsequent detection, reduces the amount of calculation in detection process.And detected by shielding Different synchronic group cells the interval corresponding peak value of peak value, it is possible to reduce the interference to subsequent detection, drop Low false drop rate.

It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings Specific embodiment of the invention is explained.

As shown in figure 1, the embodiment of the invention provides a kind of detection method of user terminal adjacent cell, institute The method of stating may include steps of：

Step 11, receives the data comprising master sync signal PSS that base station sends.

In specific implementation, after user terminal resides in suitable Serving cell, multiple base stations can be received The data of transmission, can be comprising the information such as PSS, SSS, the data sent to each base station in the data It is both needed to carry out the detection of adjacent cell.In embodiments of the invention, received wherein with the user terminal Illustrated as a example by one data r comprising master sync signal PSS of base station transmission.

Received data are made related operation by step 12 with local PSS sequences.

In specific implementation, the local PSS sequences can be obtained ahead of time and store in the user terminal 's.After getting the data r comprising master sync signal PSS, by the data r and local PSS Sequence carries out correlation, obtains channel impulse response.Can obtain desired according to the channel impulse response Peak value, the position of PSS is may determine that according to the peak value.

Step 13, related operation obtain peak value in, by from the different synchronic group cells for having detected The interval corresponding peak value shielding of peak value, and according to the letter of other synchronic group cells of the peakvalue's checking not shielded Breath.

In an embodiment of the present invention, the different peak value of each synchronic group correspondence is interval.The quantity of synchronic group, And the corresponding peak value interval of each synchronic group can pre-set.When the peak value of a cell falls into a synchronic group When corresponding peak value is interval, the cell is the cell of the synchronic group.The cell of different synchronic groups is asynchronous small Area.For example, it is [80,100] that the corresponding peak values of synchronic group A are interval, the corresponding peak values of synchronic group B are interval For [60,80), the corresponding peak value of cell 1 is 85, and the corresponding peak value of cell 2 is 74, then cell 1 is The cell of synchronic group A, cell 2 is the cell of synchronic group B, and cell 1 is asynchronous cell with cell 2.

Because the adjacent cell of the user terminal may correspond to multiple synchronic groups, therefore, obtained in related operation In the peak value for obtaining, can first by peak value corresponding from the peak value of the different synchronic group cells for having detected interval Shielding, the information of other synchronic group cells is detected further according to the peak value not shielded one by one.Wherein, it is described The different synchronic group cells for having detected at least include that the Serving cell that the user terminal is resident is corresponding same Step group.

In specific implementation, according to the peak value not shielded, other can be one by one detected using various methods The information of synchronic group cell.In one embodiment of this invention, can first to the peak value not shielded Screened, SSS detections are carried out further according to the peak value for filtering out, the result for finally being detected according to SSS is obtained Obtain the information of respective cell.

In specific implementation, the peak value not shielded can be screened using various methods. In one embodiment of the invention, N number of Preset Time point can be first pre-set, and to each Preset Time Point sets a peak threshold；Afterwards, in the peak value for being obtained from the related operation, that is, never shielded In the peak value for covering, each corresponding peak value of Preset Time point is chosen, and each Preset Time point is corresponding Peak value peak threshold corresponding with the Preset Time point is compared, and filters out more than corresponding peak threshold Preset Time point corresponding to peak value.

For example, the corresponding peak threshold of i-th Preset Time point d_time_pss (i) is d_thresld_pss (i), In the peak value that related operation is obtained, the corresponding peak value of i-th Preset Time point d_time_pss (i) is d_pss(i).Compare the size of d_pss (i) and d_thresld_pss (i), if d_pss (i) ＞ d_thresld_pss (i), Then the d_pss (i) is the peak value for filtering out.It is possible thereby to filter out multiple peak values.

In specific implementation, auxiliary synchronous signals can be carried out to the peak value for filtering out using various methods SSS is detected.It should be noted that can phase to the method that the peak value that each is filtered out carries out SSS detections Together, it is also possible to different.

In one embodiment of this invention, M Preset Time point can be first pre-set, and to each pre- If time point sets a peak threshold.After obtaining the peak value that filters out, can be filtered out according to described Peak value data of the interception comprising SSS, then the data that will be intercepted make related operation with local SSS sequences. Afterwards, from the peak value that this related operation is obtained, each corresponding peak value of Preset Time point is chosen, and Each corresponding peak value of Preset Time point peak threshold corresponding with the Preset Time point is compared, most The peak value according to corresponding to the Preset Time point more than corresponding peak threshold obtains corresponding other synchronizations afterwards The information in group of mean people area.

For example, the corresponding peak threshold of j-th Preset Time point d_time_sss (j) is d_thresld_sss (j), In the peak value that this related operation is obtained, the corresponding peak value of j-th Preset Time point d_time_sss (j) is d_sss(j).Compare the size of d_sss (j) and d_thresld_sss (j), if d_sss (j) ＞ d_thresld_sss (j), The information of corresponding other synchronic group cells is then obtained according to the d_sss (j).

It should be noted that each peak value for filtering out can correspond to multiple cells, it is also possible to only correspond to one Individual cell.That is, the information of the cell in a synchronic group can be obtained according to a peak value, also may be used Only to obtain the information of cell in multiple synchronic groups.Wherein, the strong cell of signal can correspond to larger peak Value, it is also possible to the less peak value of correspondence, and the weak cell of signal generally corresponds to less peak value, therefore, In the information of the cell in detecting other synchronic groups, can be examined by strong extremely weak order according to signal Survey, i.e., the cell of the strong synchronic group of first detection signal, further according to the information of the strong synchronic group cell of signal, The cell of the weak synchronic group of detection signal, it is to avoid during the weak cell of first detection signal, the strong cell of signal Corresponding less peak value is interfered to detection, and detection efficiency is improved with this, reduces false drop rate.

For example, the cell for having detected includes：Cell 1 in synchronic group A, the cell 2 in synchronic group B And cell 3, then cell 2 and cell 3 in cell 1, synchronic group B that can be in synchronic group A Information, the information of the cell 4 in detection synchronic group C.Further according to the cell 1 in synchronic group A, together The information of the cell 4 in cell 2 and cell 3, synchronic group C in step group B, in detection synchronic group D Cell 5 information.Continue to detect according to the method described above, until when meeting the condition for stopping detection, stopping Only detect.

It should be noted that it is unrestricted to carry out SSS detection times, can both all meeting be being filtered out SSS detections are carried out according to the peak value for filtering out respectively successively again after the peak value of condition, it is also possible in every screening After going out a qualified peak value, i.e., SSS detections are carried out according to the peak value for filtering out.

Step 14, according in the cell information detection same synchronic group detected in same synchronic group Other cell informations.

In specific implementation, according to the cell information detected in same synchronic group, can use various Method, detects other cell informations in the same synchronic group.

As shown in Fig. 2 in one embodiment of this invention, can adopt and detect described same with the following method Other cell informations in synchronic group.Specifically, methods described may include steps of：

Step 21, it is same to described k-th according to the information of the cell detected in k-th synchronic group Step group is performed except interference is operated, and k≤K, k are positive integer, and K is the sum of synchronic group.

In specific implementation, according to the information of the cell detected in k-th synchronic group, to the kth Individual synchronic group is performed except interference is operated, i.e., in the corresponding peak value interval of k-th synchronic group, reject The corresponding peak value of the cell removed is detected, it is to avoid the cell for having detected produces interference, drop to subsequent detection Low false drop rate.Wherein, except the specific method of interference operation has various, it is not restricted herein, but no matter adopt With where method carry out it is described be not construed as limiting the invention except interference is operated, and of the invention Within protection domain.

Step 22, the peak value in the peak value interval except k-th synchronic group after interference, intercepts respectively Data comprising PSS.

Step 23, the data that will be intercepted respectively make related operation with local PSS sequences.

Step 24, other cells are believed during the result according to related operation detects k-th synchronic group respectively Breath.

On step 22~24, in specific implementation, after performing k-th synchronic group except interference operation, first Remaining peak value in peak value interval according to k-th synchronic group, data of the interception comprising PSS.It Afterwards, the data that will be intercepted make related operation with local PSS sequences, multiple peak values are obtained, further according to institute The information of other cells in k-th synchronic group described in the peakvalue's checking of acquisition.Certainly, detection can be with every time Only obtain the information of a cell in k-th synchronic group, it is also possible to obtain in k-th synchronic group The information of multiple cells.

For example, k-th synchronic group is synchronic group B, cell 2, cell can be included in synchronic group B 3rd, cell 6 etc., wherein, cell 2 is the information of the cell for having detected, cell 3, cell 6 be not for The cell for detecting.Therefore, when the information of cell 3 and cell 6 is detected, can first in synchronic group B The peak value of cell 2 is rejected in corresponding peak value interval, then it is interval according to the corresponding peak values of synchronic group B respectively In remaining peak value intercept corresponding data.The data that will be intercepted are related to local PSS sequences work respectively Computing, then the result according to related operation detects the information of cell 3 respectively.When the letter for detecting cell 3 After breath, further according to cell 2 and the information of cell 3, above-mentioned detection process is repeated, detect cell 6 Information.

In specific implementation, according to the result of the related operation, can be detected using various methods, To obtain other cell informations in k-th synchronic group.

In one embodiment of this invention, first the peak value that the related operation is obtained can be screened, SSS detections are carried out to the peak value for filtering out again, to obtain other cell informations in k-th synchronic group.

Wherein, the peak value that the related operation is obtained is screened, and peak value to filtering out is carried out There are various methods in SSS detections.

In one embodiment of this invention, can adopt is carried out to the peak value that related operation is obtained with the following method Screening：N number of Preset Time point can be first pre-set, and a peak value threshold is set to each Preset Time point Value；Afterwards, in the peak value for being obtained from the related operation, that is, from the result of related operation, choosing Take each corresponding peak value of Preset Time point, and by each corresponding peak value of Preset Time point and this it is default when Between put corresponding peak threshold and be compared, filter out the Preset Time point institute more than corresponding peak threshold Corresponding peak value.

For example, the corresponding peak threshold of i-th Preset Time point d_time_pss (i) is d_thresld_pss (i), In the peak value that related operation is obtained, the corresponding peak value of i-th Preset Time point d_time_pss (i) is d_pss(i).Compare the size of d_pss (i) and d_thresld_pss (i), if d_pss (i) ＞ d_thresld_pss (i), Then the d_pss (i) is the peak value for filtering out.

In one embodiment of this invention, can adopt the peak value with the following method to filtering out carries out SSS inspections Survey：M Preset Time point can be first pre-set, and a peak threshold is set to each Preset Time point. After obtaining a peak value for filtering out, the data comprising SSS can be intercepted according to the peak value for filtering out, The data that will be intercepted again make related operation with local SSS sequences.Afterwards, obtained from this related operation Peak value in, choose each corresponding peak value of Preset Time point, and by each corresponding peak of Preset Time point Value peak threshold corresponding with the Preset Time point is compared, finally according to more than corresponding peak threshold Preset Time point corresponding to peak value obtain the information of respective cell in k-th synchronic group.

For example, the corresponding peak threshold of j-th Preset Time point d_time_sss (j) is d_thresld_sss (j), In the peak value that related operation is obtained, the corresponding peak value of j-th Preset Time point d_time_sss (j) is d_sss(j).Compare the size of d_sss (j) and d_thresld_sss (j), if d_sss (j) ＞ d_thresld_sss (j), The information of respective cell in k-th synchronic group is then obtained according to the d_sss (j).

It should be noted that each peak value for filtering out can correspond to multiple cells, it is also possible to only correspond to one Individual cell.That is, the information of the multiple cells in a synchronic group can be obtained according to a peak value, The information of a cell in a synchronic group can also only be obtained.Wherein, the strong cell of signal can be correspondingly larger Peak value, it is also possible to the less peak value of correspondence, and the weak cell of signal generally corresponds to less peak value, because This, in the information of the cell in detecting same synchronic group, can be entered according to signal by strong extremely weak order Row detection, i.e., the strong cell of first detection signal, further according to the information of the strong cell of signal, detection signal is weak Cell, it is to avoid during the weak cell of first detection signal, the corresponding less peak value pair of the strong cell of signal Detection is interfered, and detection efficiency is improved with this, reduces false drop rate.

It should be noted that in specific implementation, after each synchronic group detects cell, then can examine Survey other cells in each synchronic group, it is also possible to after the cell in detecting a synchronic group, that is, detect The information of other cells in the synchronic group.The information for detecting other synchronic group cells, with the detection Other cell informations in the same synchronic group, can be with parallel processing, it is also possible to serial process, not by suitable Sequence is limited.

It should be noted that either detecting the information of other synchronic group cells, still detect same The information of other cells in synchronic group, the cell information that will can detect is put into cell list, with It is easy to subsequently carry out the operations such as cell switching and gravity treatment.

As shown in the above, the detection method of adjacent cell described in the embodiment of the present invention, by will be in phase In the peak value that pass computing is obtained, by peak corresponding from the peak value of the different synchronic group cells for having detected interval Value shielding, so can according to the information of other synchronic group cells of the peakvalue's checking not shielded, further according to The cell information detected in same synchronic group detects other cell informations in the same synchronic group, can The quantity of peak value when carrying out subsequent detection to reduce, reduces the amount of calculation in detection process, and can subtract Few interference to subsequent detection, reduces false drop rate.In addition, the letter by first detecting different synchronic group cells Breath, then other cell informations in same synchronic group are detected, the detection time of different districts can be flexibly set, Shorten the time that whole detection process is spent.
