Detailed Description
The main purposes of the terminal for cell search include: acquiring frequency and symbol synchronization (downlink synchronization) with a cell; obtaining system frame timing, namely the initial position of a downlink frame; a Physical-layer Cell Identity (PCI) of the Cell is determined.
According to The third Generation Partnership Project (3 GPP) protocol, in The Fifth Generation mobile communication (5G) New air interface (New Radio, NR), The cell search scheme currently adopted by The terminal has The following steps:
(1) and scanning frequency points according to the frequency band configured by the high layer, and sequencing the frequency points obtained by scanning according to the signal intensity.
(2) After the frequency point scanning is finished, a plurality of candidate frequency points are screened out according to a judgment threshold, and the frequency points are all on a synchronous grid (SS-raster) and are stored in a list of frequency points to be searched.
(3) For all candidate SS-aster frequency points, according to a 3GPP protocol, each candidate frequency point needs to receive 20ms of data search Synchronization Signal Block burst (SSB burst) in sequence, and frequency point analysis is performed in sequence to determine a cell where the frequency point can reside.
(4) If the cell which can reside is not searched in the first candidate frequency point, the analysis of the second candidate frequency point is continued until the true suitable cell is searched to reside.
As the NR frequency bands commonly used in China in the 5G new air interface are N77, N78 and N79, the total bandwidth reaches 1500M, the protocol specifies that the SS-ratter frequency point step is 1.44MHz (taking more than 2.4GHz as an example), therefore, a candidate frequency point is available every 1.44MHz, and 1041 candidate SS-ratter frequency points exist in the 1500M bandwidth. In the face of such many candidate frequency points, if the steps of the conventional cell search scheme are adopted, the step of receiving the data search SSB burst of 20ms is performed on each candidate frequency point in sequence, and the cell search baseband hardware processing time after receiving the data and the subsequent software processing time are added, the cell search of one frequency point probably needs about 23 ms. The process is repeated for each candidate frequency point until a suitable frequency point resident cell is found, which results in very long cell search time and incapability of using the terminal by users in a long time.
In order to solve the above problem, an embodiment of the present application provides a cell search method, which is applicable to a terminal supporting dual carriers, and the cell search method performs parallel cell search by using at least two of a frequency point scanning accelerator, a frequency point resolution accelerator, and a processor, thereby increasing a cell search speed.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

It can be understood that the connection relationship between the two data paths and the frequency point scanning accelerator and the frequency point analysis accelerator is not fixed, in some cases, the data path CH1 is connected with the frequency point scanning accelerator, the data path CH2 is connected with the frequency point analysis accelerator, in other cases, the data path CH1 is connected with the frequency point analysis accelerator, and the data path CH2 is connected with the frequency point scanning accelerator.

Fig. 2 is a schematic flow chart of a cell search method provided in an embodiment of the present application, and as shown in fig. 2, the method includes:
step 201: and performing cell search in parallel within a preset frequency range by using at least two of a frequency point scanning accelerator, a frequency point analysis accelerator and a processor.
The cell searching process comprises the steps of carrying out frequency point scanning on the sections of the supported frequency bands by the terminal and carrying out frequency point analysis on the information of the frequency points which are obtained by the frequency point scanning and meet the preset requirements. Therefore, the terminal can adopt the frequency point scanning accelerator and the processor to respectively perform frequency point scanning on different subsections in parallel; the terminal can also synchronously utilize the frequency point scanning accelerator to scan the frequency points of the segments and utilize the frequency point analysis accelerator to analyze the frequency points meeting the preset requirements; the terminal can also adopt a frequency point analysis accelerator and a processor to analyze different frequency points to be analyzed and meeting the preset requirements in parallel.
In addition, for a terminal with three data paths, when the frequency point scanning and the frequency point analysis are synchronously performed, the processor can also perform the frequency point scanning or the frequency point analysis through the data path connected with the processor so as to complete the cell search.
In the embodiment of the application, when the terminal performs cell search, at least two of the frequency point scanning accelerator, the frequency point analysis accelerator and the processor are used for performing parallel cell search within the preset frequency range supported by the terminal, so that the cell search speed is increased, and the time required by cell search is shortened.
The present application provides several embodiments capable of shortening the search time of a cell, which are as follows:
in embodiment 1, a frequency point scanning accelerator and a processor are used to sweep frequencies of different segments in a frequency band currently subjected to frequency point scanning, and after the frequency sweeping of all frequency bands is completed, frequency point analysis is started to complete cell search, and the specific steps are shown in fig. 3:
step 301: acquiring a frequency band list supported by a terminal; the frequency band list includes information of a plurality of frequency bands supported by the terminal, such as N77, N78, N79, and the like.
Step 302: and carrying out segmentation processing on a frequency band which is not subjected to frequency point scanning in the frequency band list to obtain a segmentation list comprising a plurality of segments. Wherein each 1.44MHz in the frequency band may be divided into one segment. Currently, the step size of a specific segment may be set according to an actual situation, which is not specifically limited in this embodiment of the present application.
Step 303: judging whether a segment to be subjected to frequency point scanning exists in the segment list; if yes, go to step 304; if not, go to step 305.
Step 304: when the number of the segments to be subjected to frequency point scanning remaining in the segment list is greater than 1, simultaneously performing frequency point scanning on the segments to be subjected to frequency point scanning remaining in the segment list in parallel by using a frequency point scanning accelerator and a processor, storing the frequency points obtained by scanning, and returning to the step 303; for example: and a frequency point scanning accelerator is used for carrying out frequency point scanning on one of the multiple segments to be subjected to frequency point scanning through a data channel CH1, and a processor is used for carrying out frequency point scanning on the other one of the multiple segments to be subjected to frequency point scanning through a data channel CH 2. By scanning the frequency points of the segments, the frequency points meeting the preset conditions can be obtained. It should be noted that the data path CH2 may be considered to be directly connected to the processor at this time. Further, in this embodiment, the parallel frequency point scanning of different segments by using the frequency point scanning accelerator and the processor at the same time may be understood as starting to perform frequency point scanning by using the frequency point scanning accelerator and the processor at the same time. Specifically, when the number of remaining segments in the segment list is judged for the first time to be greater than 1, the frequency point scanning of the second segment by the processor is started while the frequency point scanning of the first segment by the frequency point scanning accelerator is started, and when the number of remaining segments in the segment list is judged again to be greater than 1 and the frequency point scanning of the third segment by the processor is started while the frequency point scanning of the third segment by the frequency point scanning accelerator is started under the condition that the frequency points scanned by the frequency point scanning accelerator and the processor are stored completely. When the total number of segments in the segment list is an even number, the number of remaining segments in the segment list is always an even number until the number of remaining segments in the segment list is 0, at this time, the step 303 determines no, and step 305 is executed. When the total number of the segments in the segment list is an odd number, the number of the remaining segments in the segment list is always an odd number until the number of the remaining segments in the segment list is 1, at this time, one of the frequency point scanning accelerator and the processor may be used to perform frequency point scanning on the segment, for example, the frequency point scanning accelerator is preferably used to perform frequency point scanning on the segment, after the frequency points obtained by scanning are stored, the step 303 is returned to execute, and the step 305 is executed if the judgment is negative.
In this embodiment, the frequency point scanning performed on different segments in parallel by using the frequency point scanning accelerator and the processor at the same time may also be understood as performing frequency point scanning by using the frequency point scanning accelerator and the processor at the same time. Specifically, when the number of remaining segments in the segment list is judged for the first time to be greater than 1, the frequency point scanning of the second segment by the processor is started while the frequency point scanning of the first segment by the frequency point scanning accelerator is started, and because there is a difference in processing rate between the frequency point scanning accelerator and the processor, for example, when the frequency point scanning of the frequency point scanning accelerator is completed first and the storage of the scanned frequency points is completed, and when the number of remaining segments in the segment list is judged again to be greater than 1, the frequency point scanning of the third segment by the frequency point scanning accelerator may still be performed by the processor. In this way, the frequency point scanning is performed on the remaining segments in the segment list until the determination in step 303 is no, and step 305 is performed.
Step 305: judging whether all frequency bands in the frequency band list complete frequency point scanning or not; if yes, go to step 306; if not, go to step 302.
Step 306: acquiring frequency points which are to be analyzed and meet preset conditions from the stored frequency points, and analyzing the frequency points meeting the preset conditions by using a frequency point analysis accelerator; the preset condition refers to a condition that can perform subsequent frequency point analysis, for example: the signal intensity of the frequency points obtained by scanning is greater than a preset threshold, or the stored frequency points are sorted according to the signal intensity, and then the frequency points with the signal intensity greater than the preset threshold are selected for frequency point analysis. After the frequency point meeting the preset condition to be analyzed is obtained, the frequency point analysis accelerator is used for analyzing the signal corresponding to the frequency point through the data channel CH2 so as to determine the cell corresponding to the frequency point which can be resided, and therefore cell search is completed.
In the embodiment, when the terminal scans the frequency points in the current frequency band for frequency point scanning, the frequency point scanning accelerator and the processor are used for scanning the frequency points in different segments in parallel, so that the hardware resources and the processor resources of the terminal can be fully utilized, the frequency point scanning speed is increased on the premise of not increasing new hardware resources, and the time required by cell searching is shortened.
In embodiment 2, a frequency point scanning accelerator is used to scan frequency bands supported by a terminal, and after scanning of all frequency bands is completed, a frequency point analysis accelerator and a processor are used to analyze frequency points meeting preset conditions, so as to complete cell search. The specific steps are shown in fig. 4:
step 401: acquiring a frequency band list supported by a terminal; the frequency band list includes information of a plurality of frequency bands supported by the terminal, such as N77, N78, N79, and the like.
Step 402: and carrying out segmentation processing on a frequency band which is not subjected to frequency point scanning in the frequency band list to obtain a segmentation list comprising a plurality of segments. Wherein each 1.44MHz in the frequency band may be divided into one segment. Currently, the step size of a specific segment may be set according to an actual situation, which is not specifically limited in this embodiment of the present application.
Step 403: judging whether a segment to be subjected to frequency point scanning exists in the segment list; if yes, go to step 404; if not, go to step 405.
Step 404: using a frequency point scanning accelerator to perform frequency point scanning on the remaining segments to be subjected to frequency point scanning in the segment list, storing the frequency points obtained by scanning, and returning to the step 403; after obtaining the plurality of segments, the frequency bin scanning accelerator performs frequency bin scanning on the plurality of segments through the data path CH 1. By scanning the frequency points of the segments, the frequency points meeting the preset conditions can be obtained.
Step 405: judging whether all frequency bands in the frequency band list complete frequency point scanning or not; if yes, go to step 406; if not, go to step 402.
Step 406: acquiring frequency points meeting preset conditions from the stored frequency points, and when the number of the frequency points meeting the preset conditions to be analyzed is more than 1, utilizing a frequency point analysis accelerator and a processor to analyze the frequency points in parallel; the preset condition refers to a condition that can perform subsequent frequency point analysis, for example: the signal intensity of the frequency points obtained by scanning may be greater than a preset threshold, and further, the stored frequency points may be sorted according to the signal intensity, and then the frequency points with the signal intensity greater than the preset threshold are selected for frequency point analysis. After the frequency point which is to be analyzed and meets the preset condition is obtained, the frequency point analysis accelerator and the processor are used for carrying out frequency point analysis on the frequency point which is to be analyzed and meets the preset condition. For example: and analyzing a signal corresponding to one frequency point to be analyzed through the data channel CH2 by using the frequency point analysis accelerator, and analyzing a signal corresponding to another frequency point to be analyzed through the data channel CH1 by using the processor to determine a cell corresponding to the frequency point which can reside, thereby completing cell search.
Further, in the present embodiment, performing frequency point analysis in parallel using the frequency point analysis accelerator and the processor may be understood as starting frequency point analysis using the frequency point analysis accelerator and the processor at the same time. Specifically, when the number of the frequency points to be analyzed is judged to be greater than 1 for the first time, the signals corresponding to the first frequency point are analyzed by using the frequency point analysis accelerator, and simultaneously, the signals corresponding to the second frequency point are analyzed by using the processor, and when the number of the frequency points to be analyzed is judged to be greater than 1 again, the signals corresponding to the third frequency point are analyzed by using the frequency point analysis accelerator, and simultaneously, the signals corresponding to the fourth frequency point are analyzed by using the processor under the condition that the cell is not successfully accessed. When the number of the frequency points meeting the preset condition is an even number, the number of the frequency points to be analyzed is always the even number, and thus the cell is accessed successfully. When the number of the frequency points meeting the preset condition is an odd number, the number of the frequency points to be analyzed is always an odd number, if the cell cannot be successfully accessed until the number of the frequency points to be analyzed is 1, at this time, one of a frequency point analysis accelerator and a processor can be used for analyzing the signal corresponding to the frequency point, for example, the frequency point analysis accelerator is preferably used for analyzing the signal corresponding to the frequency point.
In the present embodiment, the frequency point analysis performed in parallel by the frequency point analysis accelerator and the processor may be understood as performing the frequency point analysis by the processor as well as performing the frequency point analysis by the frequency point analysis accelerator. Specifically, when the number of the frequency points to be analyzed is judged to be greater than 1 for the first time, the frequency point analysis accelerator is used for analyzing the signals corresponding to the first frequency point, and the processor is used for analyzing the signals corresponding to the second frequency point, because there is a difference in processing rate between the frequency point analysis accelerator and the processor, for example, when the frequency point analysis accelerator completes frequency point analysis first and fails to access the cell successfully, and when the number of the frequency points to be analyzed is judged to be greater than 1 again, the frequency point analysis accelerator is used for analyzing the signals corresponding to the third frequency point, and the processor may still analyze the signals corresponding to the second frequency point, so until the cell is accessed successfully.
In the embodiment, after the terminal finishes the segmented frequency point scanning, the frequency point analysis accelerator and the processor are used for analyzing the information of the frequency point which is obtained by scanning and meets the preset requirement and is to be analyzed in parallel, so that the speed of frequency point analysis is increased and the time of cell search is shortened on the premise of utilizing the existing hardware resources and processor resources and not increasing new hardware resources.
In embodiment 3, a frequency point scanning accelerator is used to scan frequency points supported by a terminal, when a frequency point meeting a preset condition to be analyzed is obtained through scanning and the frequency points of all frequency bands are not scanned completely, the frequency point scanning accelerator is used to continue to scan the frequency points, and meanwhile, the frequency point analysis accelerator is used to analyze the frequency points, and when the frequency point scanning of all frequency bands is completed and the frequency points to be analyzed exist, the frequency point analysis accelerator is used to continue to analyze the frequency points. The specific steps are shown in fig. 5:
step 501: acquiring a frequency band list supported by a terminal; the frequency band list includes information of a plurality of frequency bands supported by the terminal, such as N77, N78, N79, and the like.
Step 502: and carrying out segmentation processing on a frequency band which is not subjected to frequency point scanning in the frequency band list to obtain a segmentation list comprising a plurality of segments. Wherein each 1.44MHz in the frequency band may be divided into one segment. Currently, the step size of a specific segment may be set according to an actual situation, which is not specifically limited in this embodiment of the present application.
Step 503: judging whether a segment to be subjected to frequency point scanning exists in the segment list; if yes, go to step 504; if not, go to step 505.
Step 504: using a frequency point scanning accelerator to perform frequency point scanning on the remaining segments to be subjected to frequency point scanning in the segment list, storing the frequency points obtained by scanning, and returning to the step 503; after obtaining the plurality of segments, the segments are frequency point scanned by a frequency point scanning accelerator through a data path CH 1. By scanning the frequency points of the segments, the frequency points meeting the preset conditions can be obtained.
Step 505: judging whether all frequency bands in the frequency band list complete frequency point scanning or not; if not, go to step 502.
