It will be appreciated by those skilled in the art that as described in the background art, for now, search of initial zone (Initial
Cell search, abbreviation ICS, alternatively referred to as initial cell detection) mainstay scheme using PSS and SSS realization.
Specifically, PSS detection solved by receiving the relevant operation of data and local sequence mark NID2 in group (
It can be described as N (2) _ ID)；Testing result of the SSS detection then based on PSS detection, a group mark NID1 is found out by correlation (can also claim
For N (1) _ ID)；NID1 and NID2 constitutes cell information (Physical Identity, abbreviation PID).
But since new wireless (New Radio, abbreviation NR, alternatively referred to as newly eat dishes without rice or wine) system proposes subcarrier spacing SCS
The concept of (subcarrier spacing, abbreviation SCS), for supporting the bandwidth of a variety of SCS modes simultaneously, if still using existing
ICS mode, in the grid (Synchronization Signal raster, abbreviation SS raster) of each synchronization signal
It needs to carry out repeatedly receiving number when upper trial ICS, seriously affects and search the net time.
Present inventor the analysis found that, this is because the existing received current data of ICS mode is only used for
A kind of detection of SCS mode, this results in every attempting a kind of SCS mode and will carrying out once receiving number.
In order to solve the above-mentioned technical problem, the embodiment of the present invention provides a kind of initial cell detection method, comprising: based on same
It walks block (Synchronization Signal Block, abbreviation SSB) associated maximum SCS mode and receives data, it is described
Data include the information for search of initial zone；When SSB is associated with multiple SCS modes, for every SCS mode, in the SCS
Initial cell detection is carried out to the data under mode；It is true according to the respective initial cell testing result of the multiple SCS mode
The fixed initial cell.
It will be appreciated by those skilled in the art that the scheme of the embodiment of the present invention carries out initially for the associated multiple SCS modes of SSB
The data source of foundation is same when cell detection.That is, the scheme based on the embodiment of the present invention, only need to once receive number
The initial cell detection and SCS detection for completing each SCS mode associated to SSB, effectively reduce receipts and count for several times, when net is searched in optimization
Between, it improves efficiency.
Further, the scheme of the embodiment of the present invention is to receive data based on the associated maximum SCS mode of SSB when receiving number
(i.e. the receipts number of the present embodiment is carried out according to maximum bandwidth), due to the data actually include SSB it is associated other compared with
The data of small SCS mode, thus, it, can be from reception when under other associated SCS modes of SSB to initial cell detection is carried out
Data in be partitioned into initial cell detection is carried out under the SCS mode needed for data so that it is primary receive count up into it is more
Initial cell detection and SCS detection under SCS mode are possibly realized.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this
The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow chart of initial cell detection method of the embodiment of the present invention.Wherein, the present embodiment the method
It can be applied to following scene: searching for and be resident the scene of suitable cell after terminal booting, the suitable cell is to use
The determining initial cell of the scheme detection of the present embodiment.
The present embodiment can be applied to user equipment side, and such as by user equipment, (User Equipment, abbreviation UE, can also
Referred to as terminal) it executes.
Specifically, in the present embodiment, the initial cell detection method may include steps of:
Step S101, it is associated most based on synchronization signal block (Synchronization Signal Block, abbreviation SSB)
Big SCS mode receives data, and the data include the information for search of initial zone.
Step S102, when SSB is associated with multiple SCS modes, for every SCS mode, to the number under the SCS mode
According to progress initial cell detection.
Step S103 determines the initial cell according to the respective initial cell testing result of the multiple SCS mode.
More specifically, the associated maximum SCS mode of the SSB can refer to and can prop up in the associated multiple SCS modes of SSB
The maximum bandwidth held.For example, it is assumed that SSB is associated with (also being understood as supporting) two kinds of SCS modes, respectively 30KHz (kHz)
SCS mode and 15KHz SCS mode, then in step S101 described in the present embodiment, described in SCS mode based on 30KHz receives
Data.
Further, the data volume of the received data is needed for a detection cycle of the maximum SCS mode
Data volume, that is, in NR system the single ICS period data receiver amount.For example, in NR system, ICS detection cycle is
20ms, then received data include 30KHz SCS mode under 20ms data volume.
It should be pointed out that the present embodiment includes the SCS mould of 30KHz with the associated SCS mode of SSB for the ease of statement
Two kinds of SCS modes of formula and the SCS mode of 15KHz are specifically addressed, but in practical applications, the kind of the associated SCS mode of SSB
Class can be not limited to above two (such as can also include the SCS mode of 60KHz), and those skilled in the art can be according to reality
Need to adjust the bandwidth that the associated SCS mode of the SSB is specifically supported, this scheme for not coping with the embodiment of the present invention causes to limit
System.
As a non-limiting embodiment, the step S101 may include step: to be more than or equal to the maximum SCS
The data volume that the SSB bandwidth storing initial cell detection of mode needs.
Further, the data may include the information that PSS, SSS etc. are used for cell searching.
Further, the bandwidth frequency range that the particular number of the associated SCS mode of SSB and each SCS mode are supported can be with base
It predefines and knows in agreement.
Further, with reference to Fig. 2, before actually executing initial cell detection operation, the step S102 may include
Following steps:
Step S1021 judges to carry out whether the current SCS mode of initial cell detection is the maximum SCS mode.
Further, when the judging result of the step S1021 is negative, that is, when the current SCS mode is not
When the maximum SCS mode, step S1022 can be executed, rate conversion is carried out to the data, it is described current to obtain meeting
The data of SCS mode；Step S1023 carries out initial cell detection to the data after conversion under the current SCS mode.
Otherwise, when the judging result of the step S1021 be affirmative, that is, when the current SCS mode be it is described most
When big SCS mode, step S1024 can be executed, initial cell inspection directly is carried out to the data under the current SCS mode
It surveys.
In other words, in the step S102, when (can successively or synchronize) one by one be in the associated each SCS of SSB
When carrying out initial cell detection to the data received in the step S101 under mode, need the data processing cost time
The data that SCS mode used by detecting is supported, the processing are to convert to realize based on rate.
Specifically, the rate conversion is the conversion from high-speed to low rate, will be based on higher (i.e. maximum or big
In maximum) the received data of SCS mode are converted to the data that lower SCS mode is supported.
As a non-limiting embodiment, in the step S1022, the data can be filtered,
Therefrom to extract the data for meeting the current SCS mode, the data extracted are the data after the conversion.
That is, the rate conversion can be and extract realization based on filter, with received from higher SCS mode is based on
The data of lower hertz (meeting the bandwidth that the lower SCS mode is supported) are isolated in data.
For example, the scene of two kinds of SCS modes of SCS mode of SCS mode and 15KHz for SSB association 30KHz, in institute
The symbol data that the SCS mode in step S101 based on 30KHz receives 7.68 million (M) is stated, can be led in the step S102
Wave filter is therefrom partitioned into the data that the SCS mode of 15KHz needs.
Accordingly, for different SCS modes (institute can be based on based on same data source by different filters
State the maximum received data of SCS mode) data for meeting different SCS modes are obtained, to avoid repeatedly receiving number, can be realized pair
The detection of the associated all SCS modes of SSB and initial cell detection.
In other words, above-mentioned steps S1021 to step S1024 can be understood as executing the step S102 before to the step
The preprocessing process of the data received in rapid S101.
Further, it may include steps of with reference to Fig. 3, the step S1023 or step S1024:
Step S1025 (including obtains every SCS mode based on step S1022 under the SCS mode to the data
Conversion after data and the data that are received based on step S101) carry out PSS detection, to obtain the PSS of the SCS mode
Candidate value collection.
Step S1026 concentrates the candidate value for choosing preset quantity, institute from the respective PSS candidate value of the multiple SCS mode
State the information that candidate value includes alternative initial cell.Wherein, the alternative initial cell can refer to can become UE this
One or more cells of resident initial cell.
Specifically, PSS candidate value collection may include alternative initial cell for information about.
In order to improve efficiency, optimizes data processing amount and processing speed, before carrying out SSS detection, execution institute can be passed through
It states step S1026 first to screen the respective PSS candidate value collection of the multiple SCS mode, therefrom to choose the present count
The detection basis that the candidate value of amount is detected as SSS.
Preferably, the preset quantity can be 8.In general, candidate value is more, it is better to be resident performance.In reality
In, those skilled in the art can according to need the specific value for adjusting the preset quantity, and it will not be described here.Example
Such as, precision, the quantity of the associated SCS mode of SSB that the specific value of the preset quantity can be detected with the initial cell
Etc. factors it is related.
As a non-limiting embodiment, for every SCS mode, under the SCS mode to its corresponding data into
When row PSS is detected, the step S1025 may include: to carry out relevant operation to the data and local sequence, described in obtaining
PSS candidate value collection, the PSS candidate value collection include the first correlation for being higher than the first preset threshold in the result of the relevant operation
Peak value and corresponding candidate value.Wherein, the candidate value is NID2, in addition, the PSS candidate value collection can also include each the
The reference information of the subdistrict positions such as the corresponding FOE of one correlation peak.
Specifically, PSS candidate value collection may include all of the relevant operation as a result, i.e. all the first correlation peak
And corresponding candidate value.Alternatively, initial threshold can also be preset, to make primary dcreening operation to the result of the relevant operation, therefrom select
Higher than the first correlation peak and corresponding candidate value of first preset threshold, follow-up data treating capacity is reduced, optimizes UE's
Working efficiency reduces power consumption.
Further, first preset threshold can be the ratio of correlation peak and mean value, wherein the correlation peak
It can be first correlation peak, the mean value can concentrate the adduction of all first correlation peaks for the PSS candidate value
Average value.Preferably, first preset threshold can be 6, and in practical applications, those skilled in the art can according to need
The specific value of first preset threshold is adjusted, it will not be described here.
As a change case, each correlation for including can also be concentrated to the PSS candidate value according to the first correlation peak
As a result it is ranked up, takes sequence near the preceding corresponding candidate value of the first correlation peak of one or more as the preset quantity
Candidate value in element.
In a preferred embodiment, the candidate value group that can choose identical quantity is concentrated from the PSS candidate value of each SCS mode
At the candidate value of the preset quantity, to improve reliability.
Alternatively, concentrating the quantity for the candidate value chosen to may also be distinct from that from another from the PSS candidate value of a SCS mode
The PSS candidate value of SCS mode concentrates the quantity for the candidate value chosen, with the different detection accuracy of flexible adaptation.
Further, the local sequence can be is predefined by agreement, or passes through high level instruction.
As a non-limiting embodiment, the step S1026 may include: respective from the multiple SCS mode
PSS candidate value concentrates the candidate value for choosing the corresponding highest preset quantity of first correlation peak.
It in a preferred embodiment, can be to the first relevant peaks that the respective PSS candidate value collection of the multiple SCS mode includes
Value carries out hybrid-sorting, and therefrom chooses the candidate value of the corresponding highest preset quantity of first correlation peak, to make full use of
Performance difference improves the reliability of finally determining initial cell.
For example, obtained under the SCS mode of the PSS candidate value collection and 30KHz that can obtain under the SCS mode to 15KHz
PSS candidate value collection carries out whole sequence, and the first correlation peak is higher, sorts more forward, and then therefrom chooses sequence near preceding 8
A first correlation peak and its corresponding candidate value form the candidate value of the preset quantity.
It, can be respectively from least one of respective PSS candidate value collection of the multiple SCS mode in a change case
The corresponding highest certain amount of candidate value of first correlation peak is chosen, to obtain the candidate value of the preset quantity.
For example, obtained under the SCS mode of the PSS candidate value collection and 30KHz that can be obtained under the SCS mode of 15KHz
PSS candidate value concentration is chosen respectively described in highest 4 the first correlation peaks of the first correlation peak and corresponding candidate value composition
The candidate value of preset quantity.
In another example the PSS candidate value obtained under the SCS mode of 15KHz concentrates the candidate value quantity chosen can be different
The PSS candidate value obtained under the SCS mode from 30KHz concentrates the candidate value quantity chosen, but the quantity adduction of the two is institute
State preset quantity.
For another example being obtained under the SCS mode of the PSS candidate value collection or 30KHz that can be obtained under the SCS mode of 15KHz
The PSS candidate value obtained, which is concentrated, to be chosen described in highest 8 the first correlation peaks of the first correlation peak and corresponding candidate value composition
The candidate value of preset quantity
Optionally, the step S103 may include steps of:
Step S1031, the candidate value based on the preset quantity carry out SSS detection to the data.
Step S1032 determines the initial cell based on SSS testing result.
Specifically, SSS detection can be based on PSS module position and NID2 information, the data received from step S101
Middle extraction corresponding data and the local sequence carry out relevant operation, export a certain number of candidate values, in these candidate values i.e.
Information including the initial cell.
As a non-limiting embodiment, the step S1031 may include: the candidate value for the preset quantity
In each candidate value, corresponding data are extracted from the data based on the candidate value and local sequence carries out relevant operation；
The step S1032 may include: the corresponding candidate value of maximum second correlation peak in the result based on the relevant operation
Determine the initial cell.
Further, it is carried out due to being potentially based on hybrid-sorting when the candidate value of the aforementioned determination preset quantity, thus,
When carrying out SSS detection, it is understood that there may be the corresponding data of candidate value under the SCS mode of 15KHz are carried out with the field of relevant operation
Scape.Since the step S101 data received are the SCS modes of corresponding 30KHz, thus executing the step S1031
Before, the judgment step similar to the step S1021 is needed to be implemented, in the same direction to deposit when in the candidate value of the preset quantity
In the candidate value of non-maximum SCS pattern association, rate conversion is carried out to the data, meets the non-maximum SCS mould to obtain
The data of formula.
Wherein, the particular content of the rate conversion can be refused herein with reference to the associated description in above-mentioned steps S1022
It repeats.
Alternatively, the judgment step before the step S1031 can also be omitted, then UE can store the step
Data after the conversion of S1022 medium-rate for future use, to reduce operational sequence on the basis of sacrificing memory space, improve
Detection efficiency.
By upper, using the scheme of the present embodiment, before carrying out PSS detection and SSS detection, according to current SCS to be detected
Mode is handled (or not handling) based on data for carry out ICS of the filter to storage, associated each to obtain SSB
The PSS candidate value collection of SCS mode, and then therefrom choose candidate value and carry out SSS detection, finally obtain initial cell.
Specifically, when the scheme of the embodiment of the present invention carries out initial cell detection for the associated multiple SCS modes of SSB
The data source of foundation is same.That is, the scheme based on the embodiment of the present invention, only need to once receive number be can be completed to SSB
The initial cell detection and SCS detection of associated each SCS mode, effectively reduce receipts and count for several times, the net time is searched in optimization, improves effect
Rate.
Further, the scheme of the embodiment of the present invention is to receive data based on the associated maximum SCS mode of SSB when receiving number
(i.e. the receipts number of the present embodiment is carried out according to maximum bandwidth), due to the data actually include SSB it is associated other
The data of smaller SCS mode, thus, it, can be from connecing when under other associated SCS modes of SSB to initial cell detection is carried out
