TECHNICAL FIELD

[0001] The disclosure relates to the technical field of wireless communication, and particularly to a method and device of indicating information.BACKGROUND

[0002] For a wireless spectrum in New Radio (NR), a frequency-domain position of a Synchronization Signal Block (SSB) is defined through a synchronization raster. For different frequency ranges, frequency-domain positions of synchronization rasters are determined through different formulas.

[0003] However, when there is an overlapping part between two frequency bands, positions of synchronization rasters in an overlapping frequency-domain range of the two frequency bands may be completely the same. For an initial access terminal, when an SSB is monitored at the position of the synchronization raster in a frequency-domain overlapping region, it is impossible to determine which frequency band the detected SSB belongs to, and the terminal cannot confirm a manner for subsequently transmitting and receiving signals.

[0006] In order to make the technical solutions of the embodiments of the disclosure convenient to understand, technologies related to the embodiments of the disclosure will be described below.1) SSB

[0007] A common channel and signal, for example, a Synchronization Signal (SS) and a broadcast channel, in a 5th-Generation (5G) NR system need to cover a whole cell in a multi-beam scanning manner, to facilitate the reception by User Equipment (UE) in the cell. In NR, SSB is defined. An SSB is configured to carry an SS and broadcast channel of a beam. An SSB includes a Primary Synchronization Signal (PSS) of one symbol, a Secondary Synchronization Signal (SSS) of one symbol and a New Radio Access Technology-Physical Broadcast Channel (NR-PBCH) of two symbols, as illustrated in FIG. 1 not being part of the invention.2) Synchronization raster

[0008] For a wireless spectrum in NR, a frequency-domain position of an SSB is defined through a synchronization raster. In different frequency ranges, frequency-domain positions of synchronization rasters are determined through formulas in Table 1. In a frequency range 0-3,000MHz, the frequency-domain position of the synchronization raster is calculated by use of a formula 1. In a frequency range 3,000-24,250MHz, the frequency-domain position of the synchronization raster is calculated by use of a formula 2. Table 1Frequency rangeFrequency-domain position of the SS block: SS REF GSCNGSCN range0 - 3000 MHzN*1,200kHz+M*50kHz, N=1:2,499, M∈{1,3,5} (Note 1)[3N+(M-3) / 2][2-7,498]Formula 13000-24250 MHz3,000MHz+N* 1.44 MHz[7,499+N][7,499-22,255]N=0:14,756Formula 2NOTE 1: The default value for operating frequency bands with SCS spaced channel raster is M=3.

[0009] On the other hand, frequency bands defined in NR are illustrated in Table 2. Band n38 and band n41 overlap in a frequency domain. In combination with Table 1, frequency-domain ranges of n38 and n41 belong to 0-3,000MHz, and positions of synchronization rasters in the frequency-domain ranges are determined through the formula 1 in Table 1. In an overlapping frequency-domain range of the band n38 and band n41, the positions of the synchronization rasters are completely the same. For initial access UE, when an SSB is monitored at the position of the synchronization raster in a frequency-domain overlapping region, it is impossible to determine whether a frequency band that the detected SSB belongs to is n38 or n41.

[0010] According to Table 3, for the synchronization rasters in the frequency-domain ranges of n38 and n41, a spacing of a synchronization raster defined for n38 is 1, and a spacing of a synchronization raster defined for n41 is 9. Therefore, in the frequency-domain overlapping region of n38 and n41, every ninth synchronization raster in n38 overlaps with a synchronization raster in n41.

[0011] Since the band n38 and band n41 correspond to different minimum channel bandwidths, the minimum channel bandwidth corresponding to n38 being 5MHz and the minimum channel bandwidth corresponding to n41 being 10MHz. If the UE cannot determine the frequency band through the received SSB, the minimum channel bandwidth cannot be determined, and RMSI cannot be accurately received according to indication information of an RMSI-Control Resource Set (CORESET) carried in a Master Information Block (MIB).

[0012] Since frequency-domain positions of synchronization rasters in different bands overlap, the UE cannot determine a frequency band through a frequency-domain position of a synchronization raster corresponding to a searched SSB. The embodiments of the disclosure disclose a method for determining a frequency band that the SSB belongs to through a synchronization raster of an SSB.

[0016] FIG. 2 is a first schematic flowchart of a method of indicating information according to an embodiment of the disclosure. As illustrated in FIG. 2, the method of indicating information includes the following operations.

[0017] In block 201, a terminal device receives an SSB transmitted by a network device.

[0018] In block 202, the terminal device obtains indication information according to frequency-domain position information of the SSB, the indication information being configured to indicate an attribute of a frequency band that the SSB belongs to, and the attribute of the frequency band including at least one of: an identifier of the frequency band, a minimum channel bandwidth, a subcarrier spacing of the SSB, or a subcarrier spacing of a PDCCH.

[0019] In the embodiments of the disclosure, the terminal device obtains the indication information according to a position of a synchronization raster where the detected SSB is located. Specifically, the indication information may be obtained in the following manners.

[0020] A first manner: when detecting that a frequency-domain position of the SSB corresponds to a first synchronization raster, the terminal device determines that the attribute of the frequency band that the SSB belongs to is an attribute of a first frequency band; when detecting that the frequency-domain position of the SSB corresponds to a second synchronization raster, the terminal device determines that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. Each of the first synchronization raster and the second synchronization raster is a synchronization raster in an overlapping bandwidth of the first frequency band and the second frequency band, a position of the first synchronization raster is determined based on a first formula, and a position of the second synchronization raster is determined based on a second formula.

[0021] In the embodiment of the disclosure, considering that the two frequency bands (called the first frequency band and the second frequency band in the embodiment of the disclosure) may have an overlapping part, different position calculation methods for synchronization raster (synchronization raster definitions) are adopted in the overlapping bandwidth of the first frequency band and the second frequency band, to meet the requirement that the positions of the synchronization rasters of the first frequency band and the second frequency band in the overlapping bandwidth do not overlap. The terminal device, when detecting the SSB, may determine whether the frequency band that the SSB belongs to is the first frequency band or the second frequency band according to the position of the synchronization raster where the SSB is positioned.

[0022] During specific implementation, if an original formula of determining synchronization raster position for the first frequency band is the same as an original formula of determining synchronization raster position for the second frequency band, an offset may be introduced to distinguish positions of synchronization rasters of the two frequency bands in the overlapping bandwidth.

[0023] When the first frequency band and the second frequency band are positioned in a first frequency range (for example, 0-3,000MHz in Table 1), the position of the first synchronization raster is determined based on a formula N*1,200kHz+M*50kHz, N=1:2,499, and the position of the second synchronization raster is determined based on a formula N*1,200kHz+M'*50kHz, N=1:2,499 or a formula N*1,200kHz+M*50kHz+Offset1, N=1:2,499, values of M and M' being different and Offset1 being a first offset.

[0024] When the first frequency band and the second frequency band are positioned in a second frequency range (for example, 3,000-24,250MHz), the position of the first synchronization raster is determined based on a formula 3,000Mhz+N*1.44MHz, N=0:14,756, and the position of the second synchronization raster is determined based on a formula 3,000MHz+N*1.44MHz+Offset2, N=0:14,756, Offset2 being a second offset.

[0025] For example, according to Table 1, both n38 and n41 belong to 0-3,000MHz, and positions of synchronization rasters are determined by using a formula N*1,200kHz+M*50kHz, N=1:2,499, M∈{1,3,5}. In an overlapping bandwidth of n38 and n41, the positions of the synchronization rasters of n38 and n41 are determined by using different formulas respectively. For example, for n38, the position of the synchronization raster is determined by using a formula N*1,200kHz+M*50kHz, N=1:2,499, M∈{1,3,5}; and for n41, the position of the synchronization raster is determined by using a formula N*1,200kHz+M'*50kHz, N=1:2,499, M'∈{7,9,11} or by using a formula N*1,200kHz+M*50kHz+Offset, N=1:2,499, M∈{1,3,5}, Offset being, for example, 100kHz.

[0026] A second manner: when detecting that the frequency-domain position of the SSB corresponds to a third synchronization raster, the terminal device determines that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. The third synchronization raster is a synchronization raster in an overlapping bandwidth of the second frequency band and the first frequency band; and an overlapping synchronization raster of synchronization rasters, which are determined based on a first formula and a first spacing of a synchronization raster corresponding to the first frequency band, and synchronization rasters, which are determined based on the first formula and a second spacing of a synchronization raster corresponding to the second frequency band is the third synchronization raster.

[0027] According to Table 3, for synchronization rasters in frequency-domain ranges of n38 and n41, a spacing of a synchronization raster defined for n38 is 1, and a spacing of a synchronization raster defined for n41 is 9. Therefore, in a frequency-domain overlapping region of n38 and n41, every ninth synchronization raster in n38 overlaps with a synchronization raster in n41. At frequency-domain positions of these overlapping synchronization rasters, it is specified that UE considers the frequency band corresponding to the detected SSB to be n41, but not n38.

[0028] A third manner: in the invention, when detecting that the frequency-domain position of the SSB corresponds to the third synchronization raster, the terminal device determines that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. The third synchronization raster is a synchronization raster in an overlapping bandwidth of the second frequency band and the first frequency band; a position of the third synchronization raster is determined based on a first formula and a second spacing of a synchronization raster corresponding to the second frequency band; and a synchronization raster, except the third synchronization raster, in the synchronization rasters, which are determined based on the first formula and a first spacing of a synchronization raster corresponding to the first frequency band, in the overlapping bandwidth is a synchronization raster corresponding to the first frequency band.

[0029] According to Table 3, for the synchronization rasters in the frequency-domain ranges of n38 and n41, the spacing of a synchronization raster defined for n38 is 1, and the spacing of a synchronization raster defined for n41 is 9. Therefore, in the frequency-domain overlapping region of n38 and n41, every ninth synchronization raster in n38 overlaps with a synchronization raster in n41. For these overlapping synchronization rasters, it is specified that the synchronization rasters belong to n41 and do not belong to n38. In such case, a frequency band corresponding to the SSB originally detected by the UE on these overlapping synchronization rasters is n41.

[0030] A fourth manner: when detecting that the frequency-domain position of the SSB corresponds to a fourth synchronization raster, the terminal device determines that the attribute of the frequency band that the SSB belongs to is an attribute of a first frequency band. The fourth synchronization raster is a synchronization raster in an overlapping bandwidth of the first frequency band and the second frequency band; the fourth synchronization raster is determined based on a first frequency-domain position and a third offset; and an overlapping frequency-domain position of frequency-domain positions, which are determined based on a first formula and a first spacing of a synchronization raster corresponding to the first frequency band, and frequency-domain positions, which are determined based on the first formula and a second spacing of a synchronization raster corresponding to the second frequency band, is the first frequency-domain position.

[0031] According to Table 3, for the synchronization rasters in the frequency-domain ranges of n38 and n41, the spacing of a synchronization raster defined for n38 is 1, and the spacing of a synchronization raster defined for n41 is 9. Therefore, in the frequency-domain overlapping region of n38 and n41, every ninth synchronization raster in n38 overlaps with a synchronization raster in n41. In an overlapping frequency bandwidth of n38 and n41, an offset is introduced to distinguish n38 and n41 on an overlapping synchronization raster. A specific implementation mode of the offset is similar to the first manner. The difference is that, for the overlapping synchronization rasters of n38 and n41, an offset is introduced to the synchronization raster corresponding to n38 for distinguishing the synchronization raster of n38 from the synchronization raster of n41.

[0032] FIG. 3 is a second schematic flowchart of a method of indicating information according to an embodiment of the disclosure. As illustrated in FIG. 3, the method of indicating information includes the following operation.

[0033] In block 301, a network device transmits an SSB to a terminal device, to enable the terminal device to obtain indication information according to frequency-domain position information of the SSB, the indication information being configured to indicate an attribute of a frequency band that the SSB belongs to, and the attribute of the frequency band including at least one of: an identifier of the frequency band, a minimum channel bandwidth, a subcarrier spacing of the SSB, or a subcarrier spacing of a PDCCH.

[0034] In the embodiment of the disclosure, the network device may transmit the SSB to the terminal device in the following manners.

[0035] A first manner: the network device transmits the SSB to the terminal device on a first synchronization raster, to enable the terminal device to, when detecting that a frequency-domain position of the SSB corresponds to the first synchronization raster, determine that the attribute of the frequency band that the SSB belongs to is an attribute of a first frequency band; or, the network device transmits the SSB to the terminal device on a second synchronization raster, to enable the terminal device to, when detecting that the frequency-domain position of the SSB corresponds to the second synchronization raster, determine that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. Each of the first synchronization raster and the second synchronization raster is a synchronization raster in an overlapping frequency bandwidth of the first frequency band and the second frequency band, a position of the first synchronization raster is determined based on a first formula, and a position of the second synchronization raster is determined based on a second formula.

[0036] Specifically, when the first frequency band and the second frequency band are positioned in a first frequency range, the position of the first synchronization raster is determined based on a formula N*1,200kHz+M*50kHz, N=1:2,499, and the position of the second synchronization raster is determined based on a formula N*1,200kHz+M'*50kHz, N=1:2,499 or a formula N*1,200kHz+M*50kHz+Offset1, N=1:2,499, values of M and M' being different and Offset1 being a first offset.

[0037] When the first frequency band and the second frequency band are positioned in a second frequency range, the position of the first synchronization raster is determined based on a formula 3,000Mhz+N*1.44MHz, N=0:14,756, and the position of the second synchronization raster is determined based on a formula 3,000MHz+N*1.44MHz+Offset2, N=0:14,756, Offset2 being a second offset.

[0038] A second manner: the network device transmits the SSB to the terminal device on a third synchronization raster, to enable the terminal device to, when detecting that the SSB is on the third synchronization raster, determine that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. The third synchronization raster is a synchronization raster in an overlapping bandwidth of the second frequency band and a first frequency band. An overlapping synchronization raster is the third synchronization raster, and the overlapping synchronization raster is an overlapping synchronization raster of synchronization rasters, which are determined based on a first formula and a first spacing of a synchronization raster corresponding to the first frequency band, and synchronization rasters, which are determined based on the first formula and a second spacing of a synchronization raster corresponding to the second frequency band.

[0039] A third manner: in the invention, the network device transmits the SSB to the terminal device on the third synchronization raster, to enable the terminal device to, when detecting that the SSB is on the third synchronization raster, determine that the attribute of the frequency band that the SSB belongs to is an attribute of a second frequency band. The third synchronization raster is a synchronization raster in an overlapping bandwidth of the second frequency band and the first frequency band; a position of the third synchronization raster is determined based on a first formula and a second spacing of a synchronization raster corresponding to the second frequency band. Synchronization rasters are determined based on the first formula and a first spacing of a synchronization raster corresponding to the first frequency band, in the overlapping bandwidth. A synchronization raster, except the third synchronization raster, in the synchronization rasters is a synchronization raster corresponding to the first frequency band.

[0040] A fourth manner: the network device transmits the SSB to the terminal device on a fourth synchronization raster, to enable the terminal device to, when detecting that the SSB is on the fourth synchronization raster, determine that the attribute of the frequency band that the SSB belongs to is an attribute of a first frequency band. The fourth synchronization raster is a synchronization raster in an overlapping bandwidth of the first frequency band and the second frequency band; the fourth synchronization raster is determined based on a first frequency-domain position and a third offset. An overlapping frequency-domain position is the first frequency-domain position, and the overlapping frequency-domain position is an overlapping frequency-domain position of frequency-domain positions, which are determined based on a first formula and a first spacing of a synchronization raster corresponding to the first frequency band, and frequency-domain positions, which are determined based on the first formula and a second spacing of a synchronization raster corresponding to the second frequency band.
