Description

Method and system for determining frequency domain position of synchronous signal block
Technical Field
The invention relates to a method and a system for determining the frequency domain position of a synchronous signal block, belonging to the technical field of communication.
Background
In an initial access procedure of a fifth generation mobile communication system, in each band (band), a terminal device searches for a scanning Synchronization Signal Block (SSB) on a predefined Synchronization grid (Synchronization filter) to access a cell, and acquires cell information of a target cell. The Synchronization grid may be used to indicate frequency domain locations, and the frequency domain locations of the SSBs are associated with GSCN (Global Synchronization Channel Number), which is shown in table 5.4.3.1-1 in 3GPP TS 38.104(V17.3.0), as shown in table 1:
table 1: GSCN parameters for global frequency grid
Figure BDA0003344805280000011
As shown in table 1, each synchronization trellis corresponds to a global synchronization channel number, and the specific correspondence is shown in the second column and the third column of table 1, wherein the granularity of the global synchronization channel numbers in different frequency ranges is different.
As for the synchronization signal Block, it can be divided into two categories, i.e., a Cell-defined-synchronization signal Block (CD-SSB, Cell Define SSB) and a non-Cell-defined-synchronization signal Block (NCD-SSB, None Cell Define SSB), the Cell-defined-synchronization signal Block is mainly used for initial access of a Cell and contains System Information Block 1(SIB1, System Information Block 1) Information of the access Cell, and the non-Cell-defined-synchronization signal Block is mainly used for initial access of a non-Cell, such as measurement. When an operator deploys a synchronization signal block, a non-cell-defined-synchronization signal block and a cell-defined-synchronization signal block are typically deployed together on a synchronization grid. Therefore, when the terminal searches the cell definition-synchronization signal block on the synchronization grid, the synchronization signal block searched with a certain probability is a non-cell definition-synchronization signal block. However, since the non-cell-defined-synchronization signal block does not contain the system information block 1 information of the access target cell, the terminal needs to find the target cell-defined-synchronization signal block through the non-cell-defined-synchronization signal block.
The synchronization signal Block includes a Master Information Block (MIB), which is transmitted through a physical broadcast channel, and a PBCH payload physical broadcast channel payload. The physical broadcast channel load is formed in a physical layer, occupies 8 bits and is used for representing information such as a system frame number, a field indication, a candidate synchronization signal block index and the like. The parameter "ssb-Subcarriroffset" of the Master information Block indicates the synchronization Signal Block with the control resource set #0(CORESET #0, C)Resource Element level (RE-level) offset between control-Resource Set #0), within NR (New Radio, New air interface) Frequency Range 2(FR2, Frequency Range 2), when the terminal device demodulates that the value is 12 or 13, it indicates that the synchronization signal block is a non-cell-defined synchronization signal block, i.e. it cannot be used for initial access of the cell. At this time, the terminal needs to determine the offset of the global synchronization channel number between the cell-defined-sync signal block and the non-cell-defined-sync signal block according to the controlled resource set zero and the searchSpaceZero in the parameter "pdcch-configured sib 1" in the master information block
Figure BDA0003344805280000021
Thus, the target cell definition-synchronization signal block is found through the non-cell definition-synchronization signal block, wherein the specific mapping relationship is shown in table 2:
table 2: kSSBpdcch-configSIB1 and
Figure BDA0003344805280000022
relationship between (FR2)
Figure BDA0003344805280000031
Figure BDA0003344805280000032
The value of (2) is between-256 and 256, because the Frequency band of the current fifth generation mobile communication system is in the Frequency Range of 2(FR2, Frequency Range 2) -24.25 GHz-52.6 GHz, and in the Frequency Range, the number of synchronization grids in all Frequency bands does not exceed 256.
However, in the frequency band with the lowest frequency greater than 52.6GHz, the absolute value is higher than 256 in the prior art
Figure BDA0003344805280000033
Cannot be indicated. This may increase the number of non-cell-defined synchronization signal blocks that can be searched by the terminal device, since no suitable cell-defined synchronization signal block can be foundPlus the delay of its access cell.

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1:

In the present embodiment, it is preferred that,

the frequency domain position offset characterizing the synchronization grid on which the cell-defining synchronization signal block CD-SSB and the non-cell-defining synchronization signal block NCD-SSB are located,
Figure BDA0003344805280000084
fall into [1, 256 × M ]]M is an integer not less than 2, and the number of synchronization grids in the frequency band falls into (256 in the design)(M-1)，256×M]。
In the embodiment, under the condition that the number of the synchronization grids in the frequency band is greater than 256, the number of the synchronization grids in the frequency band is adjusted
Figure BDA0003344805280000085
The value range is directly expanded, namely, the frequency domain position offset of the synchronous grids where the CD-SSB and the NCD-SSB are positioned can be realized in the frequency band
Figure BDA0003344805280000086
Is indicated.
In addition, in the present embodiment,
Figure BDA0003344805280000087
under the condition that the number of the synchronous grids in the frequency band is more than 256, the searched synchronous grid where the NCD-SSB is located indicates the synchronous grid where the corresponding CD-SSB is located, so that the time for the terminal equipment to acquire the CD-SSB can be shortened, and the time delay for the terminal equipment to access the cell can be shortened.
Further, in this embodiment, the indication parameter K for characterizing the subcarrier offset between the subcarrier zero of the CRB (Common Resource Block) and the subcarrier zero of the SSB may be set according toSSBTo determine whether the searched SSB is NCD-SSB, and can be determined according to the indication parameter K if the searched SSB is NCD-SSBSSBTo further determine the actual direction of the frequency domain positional offset. For example, when KSSB＝P1When the temperature of the water is higher than the set temperature,

Figure BDA0003344805280000091

Specifically, in the present embodiment, the interval between two adjacent CD-SSBs may be configured to be M-1, so that there are two adjacent GSCNsCD-SSBWith a spacing of M-1, and further having two adjacent
Figure BDA0003344805280000092
The interval between them is M-1. On the basis of this, the method is suitable for the production,

wherein, the value of S falls into [1, M ], the control resource set zero control resource eSetron zero and the search space zero search SpaceZero are included in the pdcch-configuration SIB1, and occupy 4 bits respectively.
Thus, in the case that the number of synchronization grids in the frequency band is greater than 256, the embodiment can adapt to the change of the number of synchronization grids in the frequency band under the condition that the configuration of the pdcch-configSIB1 and the like corresponding to the SSB is not changed, thereby implementing the method

The frequency domain position determining method of the embodiment is suitable for the case that the number of synchronization grids in a frequency band is greater than 256. At this time, the lowest frequency of the frequency band may not be less than 52.6GHz, for example, the frequency domain position determination method of this embodiment may be applied to the frequency band of 52.6GHz-71GHz, and according to the conference conclusion of RAN 1105 e, the number of synchronization grids may not exceed 665 in the frequency range of 52.6GHz-71 GHz.
For example, for a frequency range of 52.6GHz-71GHz, when the number of synchronization grids does not exceed 512, then M is 2, and thus
