[0121] In the New Radio Non-Terrestrial Network (NR NTN), beam scanning is required to achieve full coverage of all points within the coverage area. Currently, when the carrier frequency is less than 3 GHz, the maximum number of synchronization signal blocks (SSBs) in a PBCH burst set is 4. Based on a 10% coverage rate in the NTN, this only covers a maximum of 40% of the area, resulting in low coverage and poor communication efficiency.

[0122] FIG2 is an interactive diagram illustrating a method for determining a synchronization signal block SSB burst set according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for determining a synchronization signal block SSB burst set, which is used in a terminal device 101 and a network device 102. The method includes:

[0123] Step S2101: The network device determines a synchronization signal block SSB burst set.

[0124] In some embodiments, the maximum number of SSBs in an SSB burst set (SSB Burst Set) is greater than a first specified number; the first specified number is the maximum number of SSBs in an SSB burst set specified in the protocol; and / or the SSB burst set is bound to multiple areas and / or multiple cells, and the SSB burst set is used to perform beam scanning processing on multiple areas and / or multiple cells.

[0125] In one example, the maximum number of SSBs in an SSB burst set may be greater than the first specified number. In another example, the SSB burst set is bound to multiple areas and / or multiple cells, and the SSB burst set is used to perform beam scanning processing on the multiple areas and / or multiple cells. In another example, the maximum number of SSBs in an SSB burst set may be greater than the first specified number, and the SSB burst set is bound to multiple areas and / or multiple cells, and the SSB burst set is used to perform beam scanning processing on the multiple areas and / or multiple cells.

[0126] An SSB burst set is the set of SSBs required for a single beam scan. Each SSB in an SSB burst set corresponds to a beam, providing coverage for a single beam area. The greater the number of SSBs in an SSB burst set, the greater the beam area covered, resulting in a higher coverage rate. Therefore, increasing the maximum number of SSBs in an SSB burst set can improve the coverage rate of a network device's coverage area.

[0127] When an SSB burst set is bound to multiple areas, the SSB burst set and the beams in each area can be used to implement beam scanning processing in that area. Beam scanning processing for multiple areas can expand the area covered by the beam scanning processing, thereby improving the coverage rate of the network device's coverage area. The network device can divide the coverage area into regions to obtain a region set. The multiple regions mentioned here can be all regions in the region set, or they can be part of the regions in the region set.

[0128] When an SSB burst set is bound to multiple cells, beam scanning can be performed for each cell using the SSB burst set and the beams within the coverage area of ​​that cell. Beam scanning for multiple cells can expand the area covered by the beam scanning, thereby improving the coverage rate of the network device's coverage area. The multiple cells mentioned here can be all cells within the coverage area of ​​the network device, or they can be some of the cells within the coverage area of ​​the network device.

[0129] It should be noted that the beams used to send SSBs in the SSB burst set in multiple areas and / or multiple cells can have the same frequency domain or different frequency domains.

[0130] There are multiple SSB burst sets corresponding to different frequency ranges. Existing protocols set different maximum SSB numbers for SSB burst sets corresponding to different frequency ranges. Frequency ranges include, for example, 0-3 GHz, 3 GHz-6 GHz, and greater than 6 GHz.

[0131] In one example, the carrier frequency of the SSB in the SSB burst set is less than or equal to the specified frequency; the carrier frequency of the SSB in the SSB burst set specified in the protocol is less than or equal to the specified frequency. The specified frequency may be, for example, 3 GHz. That is, for an SSB burst set corresponding to a frequency range of 0 to 3 GHz, the maximum number of SSBs in the SSB burst set may be increased so that the maximum number of SSBs in the SSB burst set is greater than the first specified number. In this case, the first specified number may refer to the maximum number of SSBs in the SSB burst set corresponding to the frequency range specified in the protocol.

[0132] In another example, the carrier frequency of the SSB in the SSB burst set can be a frequency within any of the above-mentioned frequency ranges. That is, for the SSB burst set corresponding to each of the above-mentioned frequency ranges, the maximum number of SSBs in the SSB burst set can be increased so that the maximum number of SSBs in the SSB burst set is greater than the first specified number. In this case, the first specified number can refer to the maximum number of SSBs in the SSB burst set corresponding to the corresponding frequency range specified in the protocol.

[0133] The designated frequency may be determined based on a frequency range. For example, for a frequency range of 0 to 3 GHz, the designated frequency may be 3 GHz. For a frequency range of 3 GHz to 6 GHz, the designated frequency may be 6 GHz.

[0134] In general, the SSB transmission mode is CASE A mode, and the maximum number of SSBs in an SSB burst set corresponding to the 0-3 GHz frequency range specified in the protocol, that is, the first specified number, is 4. The SSB transmission mode is CASE A mode, and the maximum number of SSBs in an SSB burst set corresponding to the 3 GHz-6 GHz frequency range specified in the protocol, that is, the first specified number, is 8. The SSB transmission mode is CASE B mode, and the maximum number of SSBs in an SSB burst set corresponding to the 0-3 GHz frequency range specified in the protocol, that is, the first specified number, is 4. The SSB transmission mode is CASE B mode, and the maximum number of SSBs in an SSB burst set corresponding to the 3 GHz-6 GHz frequency range specified in the protocol, that is, the first specified number, is 8.

[0135] When the SSB transmission mode is other modes, the maximum number of SSBs in the SSB burst set is fixed in the relevant protocol and will not be described in detail here.

[0136] In some embodiments, based on the number of SSBs in the SSB burst set being less than or equal to a second specified number, the index of the SSB in the SSB burst set is indicated by a data and demodulation reference signal (DM-RS) sequence in the SSB; or, based on the number of SSBs in the SSB burst set being greater than the second specified number, the index of the SSB in the SSB burst set is indicated by a DM-RS sequence in the SSB and a specified indication bit.

[0137] Existing protocols define eight DM-RS sequences. These eight DM-RS sequences can be used to indicate the indices of up to eight SSBs. When the number of SSBs in an SSB burst exceeds eight, a combination of these eight DM-RS sequences and designated indicator bits is required to indicate the indices of more than eight SSBs. The second designated number refers to the maximum number of SSB indices that a DM-RS sequence can indicate.

[0138] In one example, based on the number of SSBs in the SSB burst set being less than or equal to the second specified number, a DM-RS sequence can be used to indicate one SSB. Correspondingly, after receiving the SSB, the terminal device can determine the index of the SSB based on the DM-RS sequence carried in the SSB. In another example, based on the number of SSBs in the SSB burst set being greater than the second specified number, a DM-RS sequence can be used to indicate two or more SSBs. Taking a DM-RS sequence indicating two SSBs as an example, any one of the two SSBs can be indicated by a designated indicator bit. Correspondingly, after receiving the SSB, the terminal device can determine the indexes of the two SSBs based on the DM-RS sequence carried in the SSB; and then determine which of the two SSB indexes to select based on the value of the designated indicator bit. For example, when the value of the designated indicator bit is 0, the first of the two SSB indexes is selected; when the number of designated indicator bits is 1, the second of the two SSB indexes is selected.

[0139] It should be noted that, when a DM-RS sequence is used to indicate two SSBs, the number of designated indication bits may be one. When a DM-RS sequence is used to indicate three or four SSBs, the number of designated indication bits may be two.

[0140] In some embodiments, to facilitate the terminal device's reception of SSBs, the network device may further transmit first information; the first information carries an indicator bit for each SSB in the SSB burst set; the indicator bit indicates whether the SSB is being transmitted. The number of indicator bits in the first information is consistent with the number of SSBs in the determined SSB burst set. For example, for each SSB, when the value of the indicator bit for the SSB is 0, it indicates that the SSB is not being transmitted; and when the value of the indicator bit for the SSB is 1, it indicates that the SSB is being transmitted.

[0141] In one example, the network device may send System Information Block 1 (SIB 1) information; the SIB1 information may carry the first information. In another example, the network device may send ServingCellConfigCommon information; the ServingCellConfigCommon information may carry the first information. In another example, the network device may send SIB1 information and ServingCellConfigCommon information; both the SIB1 information and the ServingCellConfigCommon information may carry the first information.

[0142] In some embodiments, terms such as "NR NTN", "New Radio Non-Terrestrial Network", and "New Radio Non-Terrestrial Network" can be used interchangeably.

[0143] In some embodiments, terms such as "SSB", "Synchronization Signal Block", "Synchronization Signal / PBCH Block" can be used interchangeably.

[0144] In some embodiments, the terms "NTN", "Non-Terrestrial Network", "Non-Terrestrial Network", etc. can be used interchangeably.

[0146] In some embodiments, terms such as "serving cell configuration common information" and "ServingCellConfigCommon" can be used interchangeably.

[0147] Step S2102: The network device performs beam scanning processing based on the SSB burst set.

[0148] In some embodiments, the maximum number of SSBs in an SSB burst set is greater than a first specified number; the first specified number is the maximum number of SSBs in an SSB burst set specified in the protocol; and / or the SSB burst set is bound to multiple areas and / or multiple cells, and the SSB burst set is used to perform beam scanning processing on multiple areas and / or multiple cells.

[0149] In one example, the maximum number of SSBs in the SSB burst set is greater than the first specified number. In this example, in each beam cycle scanning process, the network device can perform beam scanning based on each SSB in the SSB burst set and the beams within the coverage area.

[0150] In another example, an SSB burst set is bound to multiple areas and / or multiple cells. In this example, for each of the multiple areas within the coverage area of ​​the network device, in each beam cycle scanning process, the network device may perform beam scanning based on each SSB in the SSB burst set and the beam within the area; and / or, for each of the multiple cells within the coverage area of ​​the network device, in each beam cycle scanning process, the network device may perform beam scanning based on each SSB in the SSB burst set and the beam within the cell.

[0151] Step S2103, the terminal device receives the SSB in the SSB burst set sent by the network device.

[0152] In some embodiments, in one example, a terminal device may receive one SSB in an SSB burst set for downlink synchronization, and then perform a subsequent random access process. In another example, a terminal device may receive multiple SSBs in an SSB burst set, select one of the SSBs for downlink synchronization, and then perform a subsequent random access process.

[0223] The synchronization signal block (SSB) transmission method according to the embodiment of the present disclosure may include at least one of steps S5101 to S5103. For example, steps S5101+S5102 may be implemented as independent embodiments, and step S5103 may be implemented as an independent embodiment, etc., but the present disclosure is not limited thereto.

[0224] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0225] In the embodiments of the present disclosure, each step and its optional implementation method can also be implemented independently.

[0226] In this embodiment, the network device determines the synchronization signal block SSB burst set; the network device performs beam scanning processing based on the determined SSB burst set; the terminal device receives the SSB sent by the network device; the SSB is the SSB in the SSB burst set; wherein, the increase in the maximum number of SSBs in the SSB burst set, and / or the beam scanning processing of the SSB burst set for multiple areas and / or multiple cells can improve the coverage rate of the coverage area of ​​the network device, increase the probability of the terminal device receiving the SSB, and thereby improve communication efficiency.

[0227] The following is an exemplary introduction to the above method.

[0228] The present disclosure is used to enable network devices to increase the maximum number of SSBs in an SSB burst set and / or use the SSB burst set for beam scanning processing in multiple areas and / or multiple cells, thereby improving the coverage rate of the coverage area and thereby improving communication efficiency. Optional implementation solutions are as follows:

[0229] The present disclosure relates to a method for determining a synchronization signal block (SSB) burst set, the method comprising:

[0230] Main invention point 1: This is achieved by increasing the total number of available SSBs.

[0231] Point 1: When the SSB carrier frequency is less than 3 GHz, increase the number of SSB indices in the SSB burst set so that the number of SSB indices is greater than 4.

[0232] In some embodiments, for the case where the carrier frequency of the SSB is less than 3 GHz, the protocol stipulates that the number of SSB indexes of the SSBs in the SSB burst set is 4, and the schematic diagram of the determined SSB burst set 1 is shown in FIG6A ; in FIG6A , the transmission period of the SSB burst set is 20 ms, and 4 SSBs are transmitted in the first 5 ms of each transmission period. For the case where the carrier frequency of the SSB is less than 3 GHz, in combination with the solution disclosed in the present invention, the number of SSB indexes of the SSBs in the SSB burst set can be increased to 8, and the schematic diagram of the determined SSB burst set 2 is shown in FIG6B . In FIG6B , the transmission period of the SSB burst set is 20 ms, and 8 SSBs are transmitted in the first 5 ms of each transmission period.

[0233] In FIG6B , the number of SSB indexes of the SSB in the SSB burst set is 8. When the number of SSB indexes increases, the coverage area of ​​the coverage area can be increased, the coverage rate of the coverage area can be improved, and the communication efficiency can be improved.

[0234] Point 2: Based on Point 1, the SSB reuses the existing SSB index indication method for the newly added SSB index. If the SSB index is less than or equal to 8, it is carried through the DM-RS sequence of the PBCH; if the SSB index is greater than 8, the 3 most significant bits (MSB) are additionally indicated through information in the PBCH.

[0235] Point 3: Based on Point 1, the bit string size of ssb-PositionsInBurst in ServingCellConfigCommon (UE dedicated signaling for scell or cell resync) is modified accordingly for the case where the carrier frequency is <3GHz, that is, the information it contains should be sufficient to indicate all SSB information in the pattern; for example, the number of bits of ssb-PositionsInBurst is the same as the number of SSBs in the SSB pattern in Point 1.

[0236] Point 4: Based on the point ServingCellConfigCommonSIB (broadcast signaling SIB1), make adaptive modifications to the parameters in ssb-PositionsInBurst for carrier frequencies < 3 GHz.

[0237] Main invention point 2: achieved through base station scheduling.

[0238] Point 5: This is achieved through base station scheduling, which ensures that the maximum number of SSBs remains unchanged at 4. Areas and SSBs are implicitly bound. For example, 4 SSBs for area #1 are sent between 0 and 5 ms, and 4 SSBs for area #2 are sent between 6 and 10 ms. (Area information is transparent to the UE, and different areas correspond to different ROs with different time-frequency domain resources.)

[0239] In some embodiments, for the case where the carrier frequency of SSB is less than 3 GHz, based on FIG. 6A and in combination with the solution of point 5 of the present disclosure, after binding the SSB burst set to multiple areas, a schematic diagram of the obtained SSB burst set 3 is shown in FIG. 6C . In FIG. 6C , the number of areas bound to the SSB burst set is 4. The transmission period of the SSB burst set is 20 ms, wherein the 4 SSBs bound to area 1 (area1) are sent in 0-5 ms; the 4 SSBs bound to area 2 (area2) are sent in 5-10 ms; the 4 SSBs bound to area 3 (area3) are sent in 10-15 ms; and the 4 SSBs bound to area 4 (area4) are sent in 15-20 ms.

[0240] In FIG6C , the SSB burst set corresponds to multiple regions, and beam scanning processing can be performed in multiple regions, thereby increasing the coverage area of ​​the coverage area, improving the coverage rate of the coverage area, and thereby improving communication efficiency.

[0241] Point 6: This is achieved through base station scheduling, that is, ensuring that the maximum number of SSBs remains unchanged at 4. Replace the area ID in point 5 with the cell ID. That is, the SSBs of multiple cells are of the same frequency, but different cells are separated by physical space.

[0242] In some embodiments, for the case where the carrier frequency of the SSB is less than 3 GHz, in combination with the solution of point 6 of the present disclosure, the SSB burst set can be bound to multiple cells. Assume that the transmission period of the SSB burst set is 20 ms, and the number of cells bound to the SSB burst set is 4. Among them, the 4 SSBs bound to cell 1 (cell 1) can be sent in 0-5 ms; the 4 SSBs bound to cell 2 (cell 2) can be sent in 5-10 ms; the 4 SSBs bound to cell 3 (cell 3) can be sent in 10-15 ms; and the 4 SSBs bound to cell 4 (cell 4) can be sent in 15-20 ms, so that beam scanning processing can be performed in multiple cells, thereby increasing the coverage area of ​​the coverage area, improving the coverage rate of the coverage area, and thus improving communication efficiency.
