Specific embodiment

Currently, user terminal after the data comprising PSS for receiving base station transmission, first carries out PSS inspection to the data Survey, then to the data carry out SSS detection, so as to according to SSS detect as a result, obtain respective cell information.Wherein, PSS detection is carried out to the data, i.e., the data and local PSS sequence are made into related operation, to generate multiple peak values.To institute It states data and carries out SSS detection, i.e., corresponding data are intercepted according to the detected peak value of PSS, then by the data being truncated to and originally Ground SSS sequence makees related operation, so as to obtain corresponding small according to the result of related operation and according to identical detection time The information in area completes the detection process to adjacent cell.

However, the data can generate more peak value after PSS is detected in above-mentioned adjacent cell detection process, because This, when carrying out SSS detection according to the peak value, the calculation amount that will lead to the SSS detection is larger.Also, PSS detection generates In peak value, including the peak value of the cell detected, and the peak value of the cell detected can detect SSS and generate interference, lead SSS is caused to detect in cell obtained, false detection rate is higher.

In view of the above-mentioned problems, the embodiment provides a kind of detection method of user terminal adjacent cell, the side Method is after making related operation for the data received and local PSS sequence, will be with by by the peak value that related operation obtains The corresponding peak value shielding in the peak value section of the different synchronic group cells detected, and then can be examined according to not shielded peak value The information for surveying other synchronic group cells detects the same synchronic group further according to the cell information detected in same synchronic group In other cell informations.It, can since the corresponding peak value in peak value section of the different synchronic group cells detected has shielded The quantity of peak value when subsequent detection is carried out to reduce, and reduces the calculation amount in detection process.And it is detected by shielding The corresponding peak value in peak value section of different synchronic group cells, it is possible to reduce the interference to subsequent detection reduces false detection rate.

To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention Specific embodiment explain in detail.

As shown in Figure 1, the embodiment of the invention provides a kind of detection method of user terminal adjacent cell, the method can be with Include the following steps:

Step 11, the data comprising primary synchronization signal PSS that base station is sent are received.

In specific implementation, after user terminal resides in suitable serving cell, it can receive the number that multiple base stations are sent According to, may include the information such as PSS, SSS in the data, to each base station send data be both needed to carry out adjacent cell detection. In the embodiment of the present invention, one of base station for being received with the user terminal send comprising primary synchronization signal PSS It is illustrated for data r.

Step 12, received data and local PSS sequence are made into related operation.

In specific implementation, the local PSS sequence can be obtained ahead of time and be stored in the user terminal.It gets It is after the data r comprising primary synchronization signal PSS, the data r is related to local PSS sequence progress, obtain channel impulse Response.Desired peak value can be obtained according to the channel impulse response, may determine that the position of PSS according to the peak value.

Step 13, in the peak value that related operation obtains, by the peak value section of synchronic group cells different from what is detected Corresponding peak value shielding, and according to the information of not shielded other synchronic group cells of peak detection.

In an embodiment of the present invention, each synchronic group corresponds to different peak value sections.The quantity of synchronic group and each same The corresponding peak value section of step group can be preset.It, should when the peak value of a cell falls into the corresponding peak value section of a synchronic group Cell is the cell of the synchronic group.The cell of different synchronic groups is asynchronous cell.For example, the corresponding peak value section synchronic group A is [80,100], the corresponding peak value section synchronic group B be [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, and cell 2 is the cell of synchronic group B, and cell 1 and cell 2 are asynchronous cell.

Since the adjacent cell of the user terminal may correspond to multiple synchronic groups, in the peak value that related operation obtains In, first the corresponding peak value in the peak value section of synchronic group cells different from what is detected can be shielded, further according to not shielded Peak value detect the information of other synchronic group cells one by one.Wherein, the different synchronic group cells detected include at least The resident corresponding synchronic group of serving cell of the user terminal.

In specific implementation, according to not shielded peak value, other can be detected one by one using a variety of methods and synchronize a group of mean people The information in area.In one embodiment of this invention, first the not shielded peak value can be screened, further according to filtering out Peak value carry out SSS detection, finally according to SSS detection result obtain respective cell information.

In specific implementation, the not shielded peak value can be screened using a variety of methods.Of the invention In one embodiment, N number of preset time point can be first preset, and a peak threshold is arranged to each preset time point；Later, From the peak value that the related operation obtains, that is, in never shielded peak value, it is corresponding to choose each preset time point Peak value, and the corresponding peak value of each preset time point peak threshold corresponding with the preset time point is compared, it filters out Peak value corresponding to preset time point greater than corresponding peak threshold.

For example, the corresponding peak threshold of i-th of preset time point d_time_pss (i) is d_thresld_pss (i), In the peak value that related operation obtains, the corresponding peak value of i-th of preset time point d_time_pss (i) is d_pss (i).Compare d_ The size of pss (i) and d_thresld_pss (i), if d_pss (i) > d_thresld_pss (i), the d_pss (i) is i.e. For the peak value filtered out.It is possible thereby to filter out multiple peak values.

In specific implementation, secondary synchronization signal SSS detection can be carried out to the peak value filtered out using a variety of methods. It should be noted that the method for carrying out SSS detection to each peak value filtered out may be the same or different.

In one embodiment of this invention, M preset time point can be first preset, and each preset time point is set Set a peak threshold.It can include the data of SSS according to the peak value interception filtered out after obtaining the peak value that one filters out, The data intercepted and local SSS sequence are made into related operation again.Later, it from the peak value that the secondary related operation obtains, chooses The corresponding peak value of each preset time point, and by the corresponding peak value of each preset time point peak value corresponding with the preset time point Threshold value is compared, it is last according to peak value corresponding to the preset time point for being greater than corresponding peak threshold obtain accordingly other The information of synchronic group cell.

For example, the corresponding peak threshold of j-th of preset time point d_time_sss (j) is d_thresld_sss (j), In the peak value that the secondary related operation obtains, the corresponding peak value of j-th of preset time point d_time_sss (j) is d_sss (j).Than Compared with the size of d_sss (j) and d_thresld_sss (j), if d_sss (j) > d_thresld_sss (j), according to the d_ Sss (j) obtains the information of other corresponding synchronic group cells.

It should be noted that the peak value each filtered out can correspond to multiple cells, a cell can also be only corresponded to.? That is the information of the cell in a synchronic group can be obtained according to a peak value, can also only obtain small in multiple synchronic groups The information in area.Wherein, the strong cell of signal can correspond to biggish peak value, can also correspond to lesser peak value, and signal is weak Cell usually corresponds to lesser peak value, therefore, can be according to signal by strong when detecting the information of the cell in other synchronic groups It is detected to weak sequence, i.e., the cell of the strong synchronic group of signal is first detected, further according to the letter of the strong synchronic group cell of signal Breath, the cell of the weak synchronic group of detection signal, when avoiding formerly detecting the weak cell of signal, the strong cell of signal is corresponding smaller Peak value detection is interfered, so as to improve detection efficiency, reduce false detection rate.

For example, the cell detected includes: the cell 1 in synchronic group A, cell 2 and cell 3 in synchronic group B then may be used To detect the letter of the cell 4 in synchronic group C according to the information of the cell 1 in synchronic group A, the cell 2 in synchronic group B and cell 3 Breath.Further according to the cell 1 in synchronic group A, the information of the cell 2 in synchronic group B and the cell 4 in cell 3, synchronic group C, detection The information of cell 5 in synchronic group D.It continues to test according to the method described above, until stopping inspection when meeting the condition for stopping detection It surveys.

It should be noted that progress SSS detection time is unrestricted, can both all qualified peak values be being filtered out SSS detection is successively carried out according to the peak value filtered out respectively again afterwards, it can also be after often filtering out a qualified peak value, i.e., SSS detection is carried out according to the peak value filtered out.

Step 14, other cells in the same synchronic group are detected according to the cell information detected in same synchronic group Information.

In specific implementation, according to the cell information detected in same synchronic group, a variety of methods, detection can be used Other cell informations in the same synchronic group.

As shown in Fig. 2, in one embodiment of this invention, its in the same synchronic group can be detected with the following method His cell information.Specifically, the method may include following steps:

Step 21, according to the information of the cell detected in k-th of synchronic group, k-th of synchronic group execution is removed Interference operation, 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 of synchronic group, to k-th of synchronic group It executes except interference operation, i.e., in the corresponding peak value section of k-th of synchronic group, rejecting has detected the corresponding peak of cell removed Value avoids the cell detected from generating interference to subsequent detection, reduces false detection rate.Wherein, except the specific method of interference operation There are many, herein with no restriction, but no matter using where method progress is described except interference operation, do not constitute to limit of the invention System, and it is within the scope of the present invention.

Step 22, respectively according to the peak value in the peak value section except k-th of synchronic group after interference, interception includes PSS's Data.

Step 23, the data intercepted and local PSS sequence are made into related operation respectively.

Step 24, other cell informations in k-th of synchronic group are detected according to the result of related operation respectively.

About step 22~24, in specific implementation, k-th of synchronic group is executed after being operated except interference, first according to Remaining peak value in the peak value section of k-th of synchronic group, interception include the data of PSS.Later, by the data intercepted and local PSS sequence makees related operation, obtains multiple peak values, small further according to other in k-th of synchronic group described in peak detection obtained The information in area.Certainly, detection can only obtain the information of a cell in k-th of synchronic group every time, it is also possible to obtain described The information of multiple cells in k-th of synchronic group.

It may include cell 2, cell 3, cell 6 etc. in synchronic group B for example, k-th of synchronic group is synchronic group B, In, cell 2 is the information of the cell detected, and cell 3, cell 6 are undetected cell.Therefore, detection cell 3 and When the information of cell 6, the peak value of cell 2 can be first rejected in the corresponding peak value section synchronic group B, then respectively according to synchronic group Remaining peak value intercepts corresponding data in the corresponding peak value section B.The data intercepted are made into phase with local PSS sequence respectively Operation is closed, then detects the information of cell 3 according to the result of related operation respectively.After detecting the information of cell 3, further according to small The information of area 2 and cell 3 repeats above-mentioned detection process, detects the information of cell 6.

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

In one embodiment of this invention, the peak value that can first obtain to the related operation screens, then to screening Peak value out carries out SSS detection, to obtain other cell informations in k-th of synchronic group.

Wherein, the peak value obtained to the related operation screens, and carries out SSS detection to the peak value filtered out There are a variety of methods.

In one embodiment of this invention, the peak value that can be obtained with the following method to related operation screens: can First to preset N number of preset time point, and a peak threshold is arranged to each preset time point；Later, from the related fortune It calculates in the peak value obtained, that is, from the result of related operation, chooses the corresponding peak value of each preset time point, and will be each The corresponding peak value of preset time point peak threshold corresponding with the preset time point is compared, and is filtered out greater than corresponding peak value Peak value corresponding to the preset time point of threshold value.

For example, the corresponding peak threshold of i-th of preset time point d_time_pss (i) is d_thresld_pss (i), In the peak value that related operation obtains, the corresponding peak value of i-th of preset time point d_time_pss (i) is d_pss (i).Compare d_ The size of pss (i) and d_thresld_pss (i), if d_pss (i) > d_thresld_pss (i), the d_pss (i) is i.e. For the peak value filtered out.

In one embodiment of this invention, SSS detection: Ke Yixian can be carried out to the peak value filtered out with the following method M preset time point is preset, and a peak threshold is arranged to each preset time point.After obtaining the peak value that one filters out, It can include the data of SSS according to the peak value interception filtered out, then the data intercepted are related to local SSS sequence work Operation.Later, from the peak value that the secondary related operation obtains, the corresponding peak value of each preset time point is chosen, and will be each pre- It is last according to greater than corresponding peak value if time point corresponding peak value peak threshold corresponding with the preset time point is compared Peak value corresponding to the preset time point of threshold value obtains the information of respective cell in k-th of synchronic group.

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

It should be noted that the peak value each filtered out can correspond to multiple cells, a cell can also be only corresponded to.? That is the information of multiple cells in a synchronic group can be obtained according to a peak value, can also only obtain in a synchronic group The information of one cell.Wherein, the strong cell of signal can correspond to biggish peak value, can also correspond to lesser peak value, and signal Weak cell usually corresponds to lesser peak value, therefore, can be according to signal when detecting the information of the cell in same synchronic group It is detected by strong to weak sequence, i.e., first detects the strong cell of signal, further according to the information of the strong cell of signal, detect signal Weak cell, when avoiding formerly detecting the weak cell of signal, the corresponding lesser peak value of the strong cell of signal causes to do to detection It disturbs, so as to improve detection efficiency, reduces false detection rate.

It should be noted that in specific implementation, it can be after each synchronic group detects cell, then detect each synchronization Other cells in group, can also detect the letter of other cells in the synchronic group after detecting the cell in a synchronic group Breath.Other cell informations in the information for detecting other synchronic group cells, with the detection same synchronic group, can be simultaneously Row processing, can not also sequentially be limited with serial process.

It should be noted that either detecting the information of other synchronic group cells, still detect in same synchronic group The information of other cells, the cell information that can will test out are put into cell list, in order to subsequent progress cell switching It is operated with gravity treatment etc..

As shown in the above, the detection method of adjacent cell described in the embodiment of the present invention, by that will be obtained in related operation In the peak value obtained, the corresponding peak value in the peak value section of synchronic group cells different from what is detected is shielded, and then can basis The information of not shielded other synchronic group cells of peak detection is examined further according to the cell information detected in same synchronic group Survey other cell informations in the same synchronic group, it is possible to reduce carry out the quantity of peak value when subsequent detection, reduce detection process In calculation amount, and the interference to subsequent detection can be reduced, reduce false detection rate.In addition, by first detecting different synchronic groups The information of cell, then other cell informations in same synchronic group are detected, it can be shortened with the detection time of flexible setting different community Entire detection process the time it takes.
