Before the description of the method for receiving and transmitting the synchronization signal block, the terminal, and the network side device according to the embodiments of the present invention is performed, the following key technologies related to the embodiments of the present invention are first introduced.

1. Frequency location calibration

1.1 numbering of Spectrum resources

The frequency spectrum resources are the basis for the wireless communication to work, and the frequency spectrum resources are numbered, so that the corresponding frequency spectrum resources can be quickly found through the numbering. Table 1 lists the numbering of the third generation partnership project radio access network 4(3GPP RAN4) group for spectrum resources.

Table 1: numbering of spectrum resources

Spectrum resource	Numbering
		Frequency Range (Frequency Range)	FR1,FR2
Working frequency band (Operating Bands)	Band n1,n2,…nX
		Numbering of Channel frequency locations (RF Channel)	NR-ARFCN
Frequency numbering of SSB (SSB)	GSCN

The Frequency range of the spectrum resource can be determined by numbering the spectrum resource, a New Radio Absolute Radio Frequency Channel Number (NR-ARFCN) is the Number of the Channel Frequency position, and a Global Synchronization Raster Channel (GSCN) is the Frequency Number of the SSB.

1.2 Frequency Range (FR, Frequency Range)

Two frequency ranges are currently defined by 3GPP, denoted FR1 and FR2, respectively. In particular, FR1 represents the frequency range from 450MHz to 7125MHz, and FR2 represents the frequency range from 24250MHz to 52600 MHz. The different frequency ranges have different radio frequency characteristics and therefore need to be distinguished.

1.3 working frequency band (Operating bands)

By further dividing the frequency range (e.g. FR1, FR2), individual operating bands (operating bands) can be obtained. In NR, the representation of a frequency band consists of the letter 'n' and a frequency band number, such as the frequency bands n1, n2, n 3. Table 2 shows the operating frequency bands (parts) defined in FR 1.

TABLE 2 operating bands defined in FR1

For example, the operating band n1 has an uplink frequency range of 1920MHz-1980MHz and a downlink frequency range of 2110MHz-2170MHz, and the supported duplex mode is FDD.

1.4 channels

The working frequency band is further divided, and the channels can be obtained. The channel may be determined by the frequency location and bandwidth of the center of the channel.

2. Channel grid (Channel raster)

The 3GPP RAN4 divides the frequency resources into 3 segments, please refer to table 3, wherein, 0-3000MHz, the frequency of this segment is numbered every 5kHz (i.e. the global frequency grid of the 0-3000MHz frequency band is 5kHz), the starting frequency is 0MHz, the corresponding number is 0, and the number range of NR-ARFCN is 0-599999; 3000-24250MHz, numbering the frequency segment every 15kHz (i.e. the global frequency grid of the 3000-24250MHz band is 15kHz), the starting frequency of the numbering is 3000MHz, the corresponding numbering is 600000, and the range of the NR-ARFCN is 600000-2016666; 24250 + 100000MHz, the frequency is numbered every 60kHz (i.e. the global frequency grid of the 24250 + 100000MHz band is 60kHz), the starting frequency of the numbering is 24250.08MHz, the corresponding number is 2016667, and the range of NR-ARFCN numbers is 2016667-3279165.

Table 3: calibration of 0-100000MHz spectrum

Referring to FIG. 2, FIG. 2 is a schematic diagram of the method for determining the number of NR-ARFCNs within the 0-3000MHz spectrum, as can be seen from FIG. 2, there is one number of NR-ARFCNs for every 5 kHz.

By numbering the spectrum resources, a specific radio frequency reference frequency can be calculated, and a specific calculation formula is as follows:

F _REF ＝F _ref-offs +(N _REF -N _ref-offs )

for example, for frequency number 521, it is first determined that the corresponding frequency range is 0-3000MHz, then the global frequency grid of the frequency range is 5kHz, the starting frequency number is 0, and the frequency is 0, then the substituting formula can calculate 521 the corresponding rf frequency:

F _REF ＝0+5*(521-0)kHZ＝2605kHZ

for the frequency number 601314, it is first determined that the corresponding frequency range is 3000-:

F _REF ＝3000000+15*(601314–600000)kHZ＝3019710kHz＝3019.710MHz

NR defines a channel grid on which the base station can deploy channels. The channel grid may be 100kHz, 15kHz, 30kHz, 60kHz, 120 kHz.

For example, in Table 4, the channel grid at band n1 is 100kHz, and the uplink frequency domain corresponds to NR-ARFCN numbers ranging from 384000-. An NR-ARFCN number may also be used to indicate a frequency location.

Table 4: NR-ARFCN (Applicable NR-ARFCN per operating band) suitable for each working frequency band

3. Synchronous grid (Sync raster)

The NR network defines a synchronization grid for 0-100GHz, and the frequency location of the SSB on the operating band is SS _REF Corresponding to GSCN. The base station may transmit the SSBs on a synchronization grid. The positions and calculations of GSCNs in different frequency domain ranges are shown in table 5:

table 5: parameters of GSCN for the Global frequency raster of Global synchronization grid (GSCN parameters for the Global frequency raster)

For example, when GSCN is 2, N is 1, M is 1, and thus the corresponding frequency position is 1250 kHz.

Referring to table 6, table 6 shows the corresponding GSCN range of the operating band.

Table 6: corresponding GSCN range of operating frequency band

Referring to fig. 3, fig. 3 is a diagram illustrating a method for receiving a synchronization signal block according to an embodiment of the present invention, applied to a terminal, where the method for determining includes:

In this embodiment of the present invention, optionally, if the target frequency band includes an unavailable frequency range, the target frequency band includes at least two consecutive available sub-frequency bands.

Of course, in some other embodiments of the present invention, there may be multiple sections of the frequency range that cannot be utilized in the target frequency band, please refer to fig. 5, assuming that the frequency range of the target frequency band (e.g., NR-U band nX) is F1-F2, and there are 2 sections of the frequency ranges F3-F4 and F5-F6 that cannot be utilized in the target frequency band, at this time, the target frequency band F1-F2 may be split into 3 consecutive available sub-frequency bands F1-F5, F6-F3 and F4-F2.

In the embodiment of the present invention, optionally, if the target frequency band does not include an unavailable frequency range, the whole block of the target frequency band is used as the sub-frequency band. That is, if the target frequency band does not include an unutilized frequency range, the target frequency band is entirely a contiguous sub-band.

If the sub-channel only comprises a second SSB, the frequency position of the second SSB is located at the edge of the sub-channel, and the frequency position f of the second SSB in the first sub-channel of the sub-band ₁ Comprises the following steps:

a first SSB in the first sub-channel;

an SSB deployed in the center of the first sub-channel;

an SSB deployed at an edge of the first subchannel;

and the SSBs are deployed at other arbitrary designated positions of the first sub-channel.
