[0003] In the 3rd Generation Partnership Project (3GPP) system, if a terminal device wants to access the network via the air interface, it first searches for the Synchronization Signal Block (SSB) signal of the cell, then uses the System Information Block Type 1 (SIB1) corresponding to the SSB signal to determine the position of the SI window based on the System Information (SI) scheduling information indicated in the SIB1, so as to listen for SI messages through the SI window and then obtain other SIBs.

[0004] However, in non-terrestrial network (NTN) scenarios, a single physical beam may serve multiple cells (or beam clusters, beams, etc.) in a time-sharing manner, resulting in situations where continuous coverage cannot be provided. In this case, the current method for determining the location of the SI window cannot be applied to all cells. Summary of the Invention

[0232] In this embodiment of the invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this embodiment of the disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0233] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0234] In the 3GPP system, if a terminal device (or UE) wants to access the network via the air interface, it first searches for the Single Sideband Signal (SSB) signal of the cell, then finds SIB1 through the search space indicated by the Master Information Block (MIB) in the SSB signal, and then determines the position of the SI window according to the SI scheduling information indicated in SIB1, so as to listen for SI messages in the SI window and thus obtain other SIBs.

[0235] In NTN scenarios, a single satellite covers multiple positions. For example, the LEO-600km FR1 satellite has 1057 positions within its coverage area. However, due to limitations such as cost and processing complexity, the number of physical beams on a single satellite is relatively small (e.g., perhaps only 16). To improve coverage and efficiency in NTN scenarios, satellite physical beams need to employ a beam-hopping mechanism, meaning one physical beam needs to provide time-division multiplexing services for different positions (in the example above, one physical beam has nearly 67 positions).

[0236] In related technologies, the default SSB period during the initial access phase can be extended, for example, to 160ms. This allows the physical beam to transmit SSBs and provide random access services to different cells or different positions within the same cell in a time-division multiplexing manner, using beam hopping or beam scanning mechanisms. Multiple positions served by the same physical beam can form multiple cells or multiple position clusters, or they can belong to the same cell. These different cells (or position clusters, positions, etc.) share the same SSB index; that is, the SSB index is not extended, and the maximum number of positions within a cell still follows the existing 3GPP standard, for example, 4 positions per cell. Under this scheme, the SSB index is time-division multiplexed, and each physical beam serves multiple cells (or position clusters, positions, etc.) in a time-division multiplexing manner. For example, serving cell 1 (or position cluster 1, position 1, etc.) from 1 to 20ms, serving cell 2 (or position cluster 2, position 2, etc.) from 21 to 40ms, and so on. In this scenario, according to the existing SI window calculation formula for SI scheduling information, the starting position of the window for the first SI message calculated by all cells is fixed at SFN0 or slot0 where SFN is an integer multiple of the SI period. At the same time, each SI message maps to an SI window and the windows are arranged sequentially without overlapping. Therefore, the configured window length should not be too long, otherwise it will affect the transmission of the second SI message. This leads to the problem of SI window configuration for multiple cells (or wavelet clusters, wavelets, etc.) served by the same physical beam when the SSB extension period is (e.g., 160ms, 320ms, etc.).

[0237] To address the aforementioned issues, this disclosure proposes an SI processing method, apparatus, device, and storage medium. A network device configures configuration parameters for a terminal device, and the terminal device determines the position information of the SI window based on these parameters, enabling it to listen for SI messages within the SI window. In this embodiment, by configuring configuration parameters for each cell (or bandgap, bandgap) of the terminal device, the terminal device can use these parameters to determine the position of the SI window, thereby accurately listening for SI messages within the SI window and ensuring the reliability of the communication process.

The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in this disclosure can be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., and is not limited in this disclosure.

[0242] It should be noted that the methods and apparatus provided in the embodiments of this disclosure are based on the same application concept.

[0243] The technical solutions of the embodiments of this disclosure and how the technical solutions of this disclosure solve the above-mentioned technical problems are described in detail below with specific examples. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0244] Figure 2 is a schematic diagram of signaling interaction of an SI processing method provided in an embodiment of this disclosure. As shown in Figure 2, the SI processing method includes the following steps:

[0245] S201. Determine the configuration parameters for network devices.

[0246] In some embodiments, the network device determines configuration parameters based on beam hopping pattern information.

[0247] In some embodiments, beam hopping pattern information is used to indicate the rules of beam hopping services.

[0248] In some embodiments, beam hopping pattern information is used to indicate how to use different beam directions at different times to serve different spatial locations, thereby covering a wider area or providing better signal quality for a specific user by switching beam directions at different time intervals.

[0249] In some embodiments, beam hopping pattern information is used to indicate time information for different location areas served by the beam; wherein the time information includes, but is not limited to, at least one of the following:

[0250] Service order, service start time, service duration, or service cycle in different locations and regions.

[0251] The service period refers to the time period of the beam switching operation. During this period, the network device will switch different beam directions according to the predetermined pattern information; the location area refers to the geographical area covered by the beam switching operation.

[0252] For example, the beam serves area 1 during time period 1; serves area 2 during time period 2; ... continues to serve area 1 during time period n; and continues to serve area 2 during time period n+1. The duration from 1 to n is one service cycle of the beam.

[0253] S202, The network device sends the first SIB message to the terminal device.

[0254] In some embodiments, the first SIB message includes system information (SI) scheduling information, which in turn includes configuration parameters. The configuration parameters are used to determine the location information of the SI window, which indicates the location of the SI window listening for SI messages. The network device then uses these parameters to send the SI messages.

[0255] In some embodiments, the position information of the SI window includes the start position information and the end position information of the SI window. The start position information indicates the start position of the SI window, and the end position information indicates the end position of the SI window. The end position of the SI window is the sum of the start position and the length of the SI window.

[0256] In some embodiments, the configuration parameters are cell-level (or wavelength cluster-level, wavelength level, etc.) parameters, meaning that the configuration parameters corresponding to each cell (or wavelength cluster, wavelength, etc.) can be different.

[0257] In some embodiments, the first SIB message is an SIB1 message. The network device sends the SIB1 message to the terminal device via broadcast. Accordingly, the terminal device detects the SSB signal of the cell and decodes the SSB to obtain the first SIB message.

[0258] S203. The terminal device determines the position information of the SI window based on the configuration parameters in the SI scheduling information.

[0259] It should be understood that for the method by which the terminal device determines the position information of the SI window based on the configuration parameters, please refer to Scheme 1 to Scheme 10 in the following embodiments.

[0260] S204. Network devices send SI messages in the SI window.

[0261] In some embodiments, the network device sends an SI message in the SI window corresponding to the cell (or wavelength cluster, wavelength).

[0262] S205. The terminal device listens for SI messages in the SI window.

[0263] In some embodiments, the terminal device listens for the PDCCH of SI messages in the SI window according to the position information of the SI window, and then receives SI messages encapsulated with other SIBs (OtherSIBs, OSI) according to the PDCCH indication in order to obtain other SIBs.

[0264] It should be noted that the load status processing method involved in the embodiments of this disclosure may include at least one of steps S201 to S205. For example, steps S201 to S203 may be implemented as a standalone embodiment.

[0265] In some embodiments, the configuration parameters include, but are not limited to, at least one of the following:

[0266] The first offset is used to indicate the offset of the starting system frame number SFN in the SI window;

[0267] The first pointer parameter is used to indicate the starting position of the SI window;

[0268] The first parameter indicates the number of SI windows between the SI window and the start position or the end position of the previous SI window.

[0269] The second offset is used to indicate the interval between the SI window and the starting position or the ending position of the previous SI window;

[0270] SI message listening duration: The SI message listening duration is used to indicate the duration for which SI messages are continuously listened for in the SI window.

[0271] The third offset is used to indicate an offset that is less than or equal to the SI window length;

[0272] The listening window period corresponding to the SI listening window;

[0273] The second parameter indicates the number of continuously monitored SI windows.

[0274] The third parameter indicates the number of SI windows to skip.

[0275] The fourth parameter indicates the position of the SI window;

[0276] The first configuration parameter is used to indicate that the length of the SI window is configured as an integer multiple of the SSB period, and the SI period is configured as an integer multiple of the SSB period.

[0277] Alternatively, a second configuration parameter indicates other system information OSI search space for listening to SI messages.

[0278] It should be noted that, in this embodiment of the disclosure, the configuration parameters configured by the network device for the terminal device include, but are not limited to, any one of the above configuration parameters, or any combination of the above multiple configuration parameters.

[0279] Among these, network devices employ different configuration methods for different configuration parameters; similarly, terminal devices determine the location information of the SI window based on the configuration parameters using different methods. The following sections, using Schemes 1 to 10, will provide a detailed explanation of the configuration methods for each parameter and the methods for determining the location information of the SI window corresponding to each parameter.

[0280] Option 1: Configure the parameter as the first offset.

[0281] In some embodiments, the first offset is used to indicate the offset of the starting system frame number SFN in the SI window.

[0282] For a single cell, the dwell time of a satellite beam can cover all SI windows. Therefore, different cells (or wavelet clusters, wavelets) belonging to the same physical beam need to be configured differently so that the starting position of the SI window is within the dwell time of the satellite beam.

[0283] In some embodiments, for network devices, the first offset is obtained based on beam hopping pattern information, starting position information, SI message transmission period, number of time slots within a radio frame, and a first value. The first value is obtained based on the window length of the SI window and the order of SI scheduling information entries in the scheduling information list.

[0284] In this embodiment of the disclosure, the name of the first offset is not limited. For example, in some scenarios, "offset" can be interchanged with "SFN offset", "SI_offset", "SI window offset", "offset value", "offset parameter", etc.

[0285] In some embodiments, when configuring the first offset, the network device includes the following steps S1 to S2:

[0286] S1. Determine the first value based on the window length of the SI window and the order of SI scheduling information entries in the scheduling information list.

[0287] In some embodiments, the first value x can be determined according to the following formula (1): x=(n-1)×w (1)

[0288] Where x is the first value; n is the order of the SI scheduling information entries in the scheduling information list (or schedulingInfoList); and w is the window length of the SI window (or si-WindowLength).

[0289] S2. Obtain the first offset based on the beam transition pattern information, starting position information, SI message transmission period, number of time slots in the radio frame, and the first value.

[0290] In order to ensure that the SI window of each cell (or bandgap, bandgap, etc.) starts from the start time of beam service, the SI_offset can be determined according to the beam jump image information, so that the SFN (i.e. the starting position of the SI window) is equal to the starting SFN of the beam service of that cell (or bandgap, bandgap, etc.).

[0291] Specifically, the first offset SI_offset satisfies the following formula (2): (SFN+SI_offset)mod T=FLOOR(x / N) (2)

[0292] Where SFN is the starting position of the SI window; SI_offset is the first offset; T is the transmission period of the SI message (or si-Periodicity); and N is the number of time slots in the radio frame.

[0293] In some embodiments, the first offset (i.e., SI_offset) has a value range of (0, ..., T-1).

[0294] It should be understood that the first offset is the SI window offset at the cell level (or wavelet cluster level, wavelet level), which can be introduced in the SI-SchedulingInfo information unit in the SIB1 message (i.e. the first SIB).

[0295] In Scheme 1, for the terminal device, in some embodiments, the starting position information of the SI window is obtained based on a first offset, the transmission period of the SI message, the number of time slots within the radio frame, and a first value. The first value is obtained based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list.

[0296] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S3 to S4 are included:

[0297] S3. Obtain the first value based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list.

[0298] In some embodiments, the terminal device may determine the first value x according to the above formula (1).

[0299] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0300] S4. Determine the starting position information of the SI window based on the first offset, the transmission period of the SI message, the number of time slots in the radio frame, and the first value.

[0301] In some embodiments, after obtaining the first offset, the terminal device can determine the starting position information (i.e., SFN) of SI according to the above formula (2).

[0302] In this embodiment, the SI window listens for SI messages starting from time slot #a in the SFN (where a = xmod N). As an example, in an NTN scenario, one physical beamtime division serves 8 cells (or wavelet clusters, wavelets, etc.), and the SSB period is 160ms. In the first SSB period, cell 1 (or wavelet cluster 1, wavelet 1, etc.) serves for 1-20ms, cell 2 (or wavelet cluster 2, wavelet 2, etc.) serves for 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf16 (i.e., 16 radio frames, T is 16), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5).

[0303] To ensure that the SI window for each cell (or bandgap, bandgap, etc.) starts from the beam service start time, the first offset needs to be configured at the cell level. The first offset for cell 1 (or bandgap cluster 1, bandgap 1, etc.) is 0; the first offset for cell (or bandgap cluster 2, bandgap 2, etc.) is 14; the first offset for cell 3 (or bandgap cluster 3, bandgap 3, etc.) is configured to 12; the first offset for cell 4 (or bandgap cluster 4, bandgap 4, etc.) is configured to 10; the first offset for cell 5 (or bandgap cluster 5, bandgap 5, etc.) is configured to 8; the first offset for cell 6 (or bandgap cluster 6, bandgap 6, etc.) is configured to 6; the first offset for cell 7 (or bandgap cluster 7, bandgap 7, etc.) is configured to 4; and the first offset for cell 8 (or bandgap cluster 8, bandgap 8, etc.) is configured to 2.

[0304] Under this configuration, the positions of the first SI window of these 8 cells within a 160ms SSB period are shown in Figure 3a.

[0305] In this embodiment of the disclosure, by introducing a cell-level (or wavelet cluster-level, wavelet-level) first offset, each cell (or wavelet cluster, wavelet) can use the first offset to determine the starting position of the SI window, and then match the SFN at the beginning of the SI window with the starting SFN of the beam serving the cell (or wavelet cluster, wavelet), thereby accurately listening to SI messages in the SI window and ensuring the reliability of the communication process.

[0306] Option 2: Configure the parameter as the first pointer parameter.

[0307] In some embodiments, the first pointer parameter is used to indicate the starting position of the SI window.

[0308] For a single cell, the dwell time of a satellite beam can cover all SI windows. Therefore, different cells (or wavelet clusters, wavelets) belonging to the same physical beam need to be configured differently so that the starting position of the SI window is within the dwell time of the satellite beam.

[0309] In some embodiments, for network devices, the first pointer parameter is obtained based on beam hopping pattern information, start position information, SI message transmission period, number of time slots within a radio frame, and a first value. The first value is obtained based on the window length of the SI window and the order of SI scheduling information entries in the scheduling information list.

[0310] In this embodiment of the disclosure, the name of the first pointer parameter is not limited. For example, in some scenarios, "pointer parameter" can be interchanged with "indicator parameter", "start pointer parameter", "si-WindowStart", "start indicator parameter", etc.

[0311] In some embodiments, to ensure that the SI window for each cell (or bandgap, bandgap, etc.) starts from the beam service start time, the network device can configure a first pointer parameter based on beam transition image information to determine the number of windows that the SI window start position (i.e., SFN) of each cell (or bandgap, bandgap, etc.) needs to be offset from the system frame start position. When configuring the first pointer parameter, the value of (si-WindowStart*si-WindowLength) / N must be equal to an integer multiple of the number of radio frames required for cell (or bandgap, bandgap, etc.) service.

[0312] In some embodiments, when configuring the first pointer parameter, the network device includes the following steps S5 to S6:

[0313] S5. Obtain the first value x based on the starting position information, the SI message transmission period, and the number of time slots in the radio frame.

[0314] In some embodiments, the first value x satisfies the following formula (3): SFN mod T=FLOOR(x / N) (3)

[0315] Where x is the first value; SFN is the starting position of the SI window determined by the network device based on the beam hopping pattern information; T is the transmission period of the SI message (or si-Periodicity); and N is the number of time slots in the radio frame.

[0316] S6. Determine the first pointer parameter based on the first value, the window length of the SI window, and the order of the SI scheduling information entries in the scheduling information list.

[0317] In some embodiments, the first pointer parameter s also satisfies the following formula (4): x=(s+n-1)×w (4)

[0318] Where s is the first pointer parameter; n is the order of the SI scheduling information entries in the scheduling information list (or schedulingInfoList); and w is the window length of the SI window (or si-WindowLength).

[0319] It should be understood that the first pointer parameter can be introduced in the SI-SchedulingInfo information unit in the SIB1 message (i.e., the first SIB).

[0320] In Scheme 2, for the terminal device, in some embodiments, the starting position information is obtained based on the SI message transmission period, the number of time slots within the radio frame, and a first value. The first value is obtained based on a first pointer parameter, the window length of the SI window, and the order of the SI scheduling information entries in the scheduling information list.

[0321] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S7 to S8 are included:

[0322] S7. Determine the first value based on the first pointer parameter, the window length of the SI window, and the order of the SI scheduling information entries in the scheduling information list.

[0323] In some embodiments, after obtaining the first pointer parameter, the terminal device can determine the first value x according to the above formula (4).

[0324] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0325] S8. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0326] In some embodiments, the terminal device may determine the starting position information (i.e., SFN) of the SI window according to the above formula (3).

[0327] In this embodiment, the SI window starts from slot #a in the SFN, where a = xmod N. As an example, in an NTN scenario, one physical beam serves 8 cells (or bands, bands, etc.) in a time division, with an SSB period of 160ms. In the first SSB period, cell 1 (or band 1, band 1, etc.) serves for 1-20ms, cell 2 (or band 2, band 2, etc.) serves for 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf16 (i.e., 16 radio frames, T is 16), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5).

[0328] To ensure that the SI window for each cell (or bandgap, bandgap, etc.) starts from the beam service start time, the first pointer parameter needs to be configured at the cell level so that the value of (si-WindowStart*si-WindowLength) / N is equal to an integer multiple of the number of radio frames required for the cell (or bandgap, bandgap, etc.) service. For example, the first pointer parameter (i.e., si-WindowStart) of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is configured to 0, the first pointer parameter (i.e., si-WindowStart) of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is configured to 4, the first pointer parameter (i.e., si-WindowStart) of cell 3 (or wavelet cluster 3, wavelet 3, etc.) is configured to 8, the first pointer parameter (i.e., si-WindowStart) of cell 4 (or wavelet cluster 4, wavelet 4, etc.) is configured to 12, the first pointer parameter (i.e., si-WindowStart) of cell (or wavelet cluster 5, wavelet 5, etc.) is configured to 16, the first pointer parameter (i.e., si-WindowStart) of cell 6 (or wavelet cluster 6, wavelet 6, etc.) is configured to 20, the first pointer parameter (i.e., si-WindowStart) of cell 7 (or wavelet cluster 7, wavelet 7, etc.) is configured to 24, and the first pointer parameter (i.e., si-WindowStart) of cell 8 (or wavelet cluster 8, wavelet 8, etc.) is configured to 28.

[0329] With this configuration, the positions of the first SI window of these 8 cells within a 160ms SSB period are shown in Figure 3b.

[0330] In this embodiment of the disclosure, by configuring a first pointer parameter for the terminal device so that the value of (si-WindowStart*si-WindowLength) / N is equal to an integer multiple of the number of radio frames required for cell (or wavelet cluster, berth) service, each cell (or wavelet cluster, wavelet) can use the first pointer parameter to determine the starting position of the SI window, and then match the SFN at the beginning of the SI window with the starting SFN of the beam serving the cell (or wavelet cluster, wavelet), thereby accurately listening to SI messages in the SI window and ensuring the reliability of the communication process.

[0331] Option 3: Configure the first parameter.

[0332] In some embodiments, the first parameter is used to indicate the number of SI windows between the start position and the end position of the previous SI window.

[0333] In some embodiments, if a satellite beam's single dwell time can provide sufficient service time for one or more SI windows, but cannot continuously provide continuous SI service, then SI scheduling cannot be continuous, resulting in some SI window locations having no serving beams. Therefore, in this embodiment, a first parameter mn is configured to indicate the number of SI windows between the SI window and its starting position or the ending position of the previous SI window. For example, the scheduling SI window of the nth SI is separated from the scheduling SI window of the (n-1)th SI by mn SI windows. By configuring the mn value, the position of the SI window is adjusted so that the SI window falls within the service time of the beam.

[0334] In some embodiments, for network devices, the first parameter is obtained based on beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and a first value. The first value is obtained based on the starting position information, the transmission period of the SI message, and the number of time slots within the radio frame.

[0335] In this embodiment of the disclosure, the name of the first parameter is not limited. For example, in some scenarios, "first parameter" can be interchanged with "offset window coefficient", "first coefficient", "offset window parameter", etc.

[0336] In some embodiments, the value of the first parameter (mn) represents the number of window lengths between the start position of the nth SI window and the end position of the (n-1)th SI window. Specifically, when configuring the first parameter based on the beam transition pattern information, if j SI windows can be consecutively and closely arranged within the beam's service time, then mi(i=1,…,j)=0, while ensuring that j*w is less than or equal to the beam's service time; the (j+1)th window will only appear after the next beam's service time. Therefore, mj+1 = (beam period - j*w) / w.

[0337] In some embodiments, when configuring the first parameter, the network device includes the following steps S9 to S10:

[0338] S9. Determine the first value based on the starting position information, the transmission period of the SI message, and the number of time slots in the radio frame.

[0339] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0340] S10. Determine the first parameter based on the beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and the first value.

[0341] The first parameter also satisfies the following formula (5):

[0342] Where mi is the first parameter corresponding to the i-th SI window, i = (1, ..., n); n is the order of the SI scheduling information entries in the scheduling information list (or schedulingInfoList); and w is the window length of the SI window (or si-WindowLength). In Scheme 3, for the terminal device, in some embodiments, the starting position information is obtained based on the SI message transmission period, the number of time slots in the radio frame, and a first value. The first value is obtained based on a first part and a second part. The first part is obtained based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list; the second part is obtained based on the first parameter and the window length of the SI window.

[0343] The first part is (n–1)×w; the second part is

[0344] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S11 to S12 are included:

[0345] S11. Determine the first part based on the window length of the SI window and the order of SI scheduling information entries in the scheduling information list; determine the second part based on the first parameter and the window length of the SI window; determine the first value based on the first part and the second part.

[0346] In some embodiments, after obtaining the first parameter, the terminal device can determine the first value x according to the above formula (5).

[0347] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0348] S12. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0349] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0350] In some embodiments, the intervals between SIs can also be fixed, meaning that the intervals between each SI window are the same. In this case, the first value x = (n–1)×w + (n-1)×m×w, which means the interval between each SI window is m×w. In some embodiments, an example diagram of the SI window is shown in Figure 3c.

[0351] In this embodiment, the SI window starts from slot #a in the SFN, where a = x mod N. As an example, in an NTN scenario, one physical beam serves 8 cells (or bands, bands, etc.) in a time division, with an SSB period of 160ms. In the first SSB period, cell 1 (or band 1, band 1, etc.) serves for 1-20ms, cell 2 (or band 2, band 2, etc.) serves for 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf16 (i.e., 16 radio frames, T is 16), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5).

[0352] In this scenario, for a cell (or bandgap, band position, etc.), four SI-windows can be configured within one SSB cycle. The fifth SI-window (i.e., the SI window) needs to wait until the second SSB cycle. If a cell (or bandgap, band position, etc.) has five SI-windows, then the configuration of cell 1 (or bandgap 1, band position 1, etc.) can be: m1=0, m2=0, m3=0, m4=0, m5=28. In some embodiments, an example diagram of the SI window in this embodiment is shown in Figure 3d.

[0353] In this embodiment of the disclosure, by configuring a first parameter for the terminal device to indicate the number of SI windows between each SI window and its starting position or the ending position of the previous SI window, each cell (or bandgap cluster, bandgap) can use the first parameter to determine the starting position of the SI window, and then match the SFN of the starting SI window with the starting SFN of the beam serving the cell (or bandgap cluster, bandgap), thereby accurately listening to SI messages in the SI window and ensuring the reliability of the communication process.

[0354] Option 4: Configuration parameters include the second offset and SI message listening duration.

[0355] In some embodiments, the second offset is used to indicate the interval between the SI window and the start position or the end position of the previous SI window, and the SI message listening duration is used to indicate the duration for which SI messages are continuously listened to in the SI window.

[0356] In some embodiments, the length of the SI window can be extended. However, within this SI window, the satellite beams serve different cells (or beam clusters, beams, etc.) based on TDD mode. Therefore, the terminal device can only listen to SI messages for a portion of the SI window. By configuring a second offset and the SI message listening duration, after determining the starting position of the SI window, the terminal device delays the start of SI message reception by the second offset, and the duration of SI message reception is equal to the SI message listening duration.

[0357] It should be noted that the configuration parameters (i.e., the second offset and the SI message listening duration) of different SI windows can be the same or different.

[0358] In some embodiments, for the network device, the duration of SI message listening needs to be less than or equal to the window length w of the SI window, and the duration of SI message listening needs to be less than or equal to the beam service duration; the second offset is obtained based on the beam transition pattern information, the window length of the SI window, the order of the SI scheduling information entries in the scheduling information list, and the first value. The first value is obtained based on the starting position information, the SI message transmission period, and the number of time slots within the radio frame.

[0359] In this embodiment of the disclosure, the names of the second offset and the SI message listening duration are not limited. For example, in some scenarios, "offset" can be replaced with "time slot offset", "time slot offset parameter", "offset", etc.; "SI message listening duration" can be replaced with "listening duration", "listening time period", "receiving duration", "SI listening duration", "SI message listening time", "duration", etc.

[0360] In some embodiments, the network device can configure a second offset based on beam hopping pattern information to adjust the number of time slots required between the first SI window and the starting position of the beam service or adjacent windows, so that the starting position of the SI window is within the service time of the serving beam.

[0361] In some embodiments, when configuring the second offset, the network device includes the following steps S13 to S14:

[0362] S13. Determine the first value based on the starting position information of the SI window, the transmission period of the SI message, and the number of time slots in the radio frame.

[0363] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0364] S14. Determine the second offset based on the beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and the first value.

[0365] In some embodiments, the second offset also satisfies the following formula (6): x=(n-1)×w+offset (6)

[0366] Where offset is the second offset, n is the order of SI scheduling information entries in the scheduling information list (or schedulingInfoList); w is the window length of the SI window (or si-WindowLength).

[0367] In Scheme 4, for the terminal device, in some embodiments, the starting position information is obtained based on the SI message transmission period, the number of time slots within the radio frame, and a first value. The first value is obtained based on a first part and a second offset; the first part is obtained based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list.

[0368] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S15 to S16 are included:

[0369] S15. Determine the first part based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list; determine the first value based on the first part and the second offset.

[0370] In some embodiments, after obtaining the second offset, the terminal device can determine the first value x according to the above formula (6). Wherein, the first part is (n-1)×w.

[0371] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0372] S16. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0373] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0374] In this embodiment, the SI window starts from slot #a in the SFN, where a = x mod N. As an example, in an NTN scenario, one physical beam serves 8 cells (or bands, bands, etc.) in a time division, with an SSB period of 160ms. In the first SSB period, cell 1 (or band cluster 1, band 1, etc.) serves for 1-20ms, cell 2 (or band cluster 2, band 2, etc.) serves for 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf16 (i.e., 16 radio frames, T is 16), si-WindowLength is configured as s160 (i.e., 160 slots, w is 160); the SI message listening duration is s5 (i.e., the SI message listening duration is 5 slots).

[0375] The second offset is configured so that the starting position of the SI window is within the cell service time. Specifically, the second offset of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is configured to 0, the second offset of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is configured to 20, the value of cell 3 (or wavelet cluster 3, wavelet 3, etc.) is 40, the second offset of cell (or wavelet cluster 4, wavelet 4, etc.) is configured to 60, the second offset of cell 5 (or wavelet cluster 5, wavelet 5, etc.) is configured to 80, the second offset of cell 6 (or wavelet cluster 6, wavelet 6, etc.) is configured to 100, the second offset of cell 7 (or wavelet cluster 7, wavelet 7, etc.) is configured to 120, and the second offset of cell 8 (or wavelet cluster 8, wavelet 8, etc.) is configured to 140.

[0376] Under this configuration, assuming that each cell (or bandgap cluster, bandgap, etc.) has only one SI window within one SSB cycle, an example diagram of the SI window is shown in Figure 3e.

[0377] In this embodiment of the disclosure, by configuring a second offset and SI message listening duration for the terminal device, each cell (or band cluster, band) can use the second offset to determine the starting position of the SI window, thereby matching the SFN at the beginning of the SI window with the starting SFN of the beam serving the cell (or band cluster, band). By listening to SI messages in the SI window according to the SI message listening duration, SI messages can be accurately listened to, thereby ensuring the reliability of the communication process.

[0378] Option 5: The configuration parameters include the first parameter, the third offset, and the SI message listening duration.

[0379] In some embodiments, the first parameter is used to indicate the number of SI windows between the SI window and the starting position or the ending position of the previous SI window; the third offset is used to indicate an offset that is less than or equal to the length of the SI window; and the SI message listening duration is used to indicate the duration for which SI messages are continuously listened to in the SI window.

[0380] For network devices, in some embodiments, the first parameter and the third offset are obtained based on beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and a first value. The first value is obtained based on the starting position information, the transmission period of the SI message, and the number of time slots within the radio frame.

[0381] In some embodiments, the value of the first parameter (mn) represents how many window lengths are between the start position of the nth SI window and the end position of the (n-1)th SI window; the value of the third offset (offsetn) is configured to be a slot offset value less than or equal to w.

[0382] In some embodiments, the network device can determine, based on the beam hopping pattern, that j SI windows can be continuously and closely arranged within the service time of the beam. In this case, mn (n = 1, ..., j) = 0. If it is desired that the starting position of the first SI window has a certain offset n from the start point of the system frame (where the value of offset n is less than or equal to w), then offset1 is configured as an integer value between 0 and si-WindowLength, while ensuring that j*w is less than or equal to the service time of the beam. That is, when the (j+1)th window needs to wait until the next beam visit service before it appears, then mj+1 = FLOOR[(beam period - j*w) / w].

[0383] In some embodiments, when configuring the third offset and the first parameter, the network device includes the following steps S17 to S18:

[0384] S17. Determine the third offset and the first parameter based on the starting position information, the transmission period of the SI message, and the number of time slots in the wireless frame.

[0385] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0386] S18. Based on the beam hopping pattern information, the window length of the SI window, the order of the SI scheduling information entries in the scheduling information list, and the first value, determine the first parameter and the third offset.

[0387] In some embodiments, the third offset (offsetn) and the first parameter (mi) also satisfy the following formula (7).

[0388] Where offsetn is the third offset, mi is the first parameter of the i-th SI window, i = (1, ..., n); n is the order of the SI scheduling information entries in the scheduling information list (or schedulingInfoList); w is the window length of the SI window (or si-WindowLength).

[0389] In Scheme 5, for the terminal device, in some embodiments, the starting position information is obtained based on the transmission period of the SI message, the number of time slots in the radio frame, and a first value; wherein, the first value is obtained based on a first part, a second part, and a third offset; the first part is obtained based on the window length of the SI window and the order of the SI scheduling information entries in the scheduling information list; the second part is obtained based on a first parameter and the window length of the SI window.

[0390] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S19 to S20 are included:

[0391] S19. Determine the first part based on the window length of the SI window and the order of SI scheduling information entries in the scheduling information list; determine the second part based on the first parameter and the window length of the SI window; determine the first value based on the first part, the second part, and the third offset.

[0392] In some embodiments, the terminal device may determine the first value x according to the above formula (7).

[0393] The first part is (n–1)×w, and the second part is

[0394] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0395] S20. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0396] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0397] In this embodiment of the disclosure, as an example, in an NTN scenario, one physical beam serves 8 cells (or wavelet clusters, wavelets, etc.) in a time division multiplexing manner. The SSB period is 160ms. Within the first SSB period, the service time of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is 1-20ms, the service time of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf32 (i.e., 32 radio frames, T is 32), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5).

[0398] In this scenario, for a cell (or bandgap cluster, bandgap, etc.), if it is desired that the starting position of the first SI window has a certain offset n from the starting point of the system frame (this offset is less than or equal to si-WindowLength), and that the SI windows are closely arranged within one SSB cycle, then a maximum of 3 SI windows can be configured within one SSB cycle. If the cell (or bandgap cluster, bandgap, etc.) has 5 SI windows, and the 4th and 5th SI windows need to wait until the second SSB cycle, then the configuration of cell 1 (or bandgap cluster 1, bandgap 1, etc.) can be: m1=0, m2=0, m3=0, m4=28, m5=0; offset1=2, offset2=2, offset3=2, offset4=2, offset5=2; duration=s5 (5 slots). For example, the SI window of cell 1 (or bandgap cluster 1, bandgap 1, etc.) is shown in Figure 3f.

[0399] In this embodiment of the disclosure, by configuring a first parameter, a third offset, and the listening duration of the SI window for the terminal device, each cell (or band cluster, band position) can use the first parameter and the third offset to determine the starting position of the SI window, and then match the SFN at the beginning of the SI window with the starting SFN of the beam serving the cell (or band cluster, band position), and listen for SI messages in the SI window according to the SI message listening duration, so that the SI messages can be accurately listened for, thereby ensuring the reliability of the communication process.

[0400] Option 6: Configuration parameters include the second offset and SI message listening duration.

[0401] In some embodiments, the second offset is used to indicate the interval between the SI window and its starting position or the ending position of the previous SI window, and the SI message listening duration is used to indicate the duration for which SI messages are continuously listened to within the SI window. The SI message listening duration is determined based on the transition pattern information, and its value is less than or equal to the beam's service duration.

[0402] In some embodiments, if a satellite can continuously serve multiple SI windows for the same cell (or wavelet cluster, wavelet, etc.), but cannot continuously serve one or more cycles, a second offset and SI message listening duration can be indicated to the terminal device to determine a listening window within one SI cycle. Within this window, SI scheduling is listened to in the default manner.

[0403] It should be noted that the method for configuring the second offset and SI message listening duration for network devices, and the method for determining the SI listening window based on the second offset and SI message listening duration for terminal devices, are described in Scheme 4 above and will not be repeated here.

[0404] For example, the terminal device can determine the positions that can be monitored within an SI cycle as SFNstart, slotstart, SFNend, and slotend based on the second offset and the SI message listening duration.

[0405] Furthermore, the terminal device determines the first value x according to formula (1) in Scheme 1, and determines the starting position (i.e. SFN) of the SI window according to formula (3) in Scheme 2.

[0406] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0407] When listening to the SI window, if the terminal device determines that the SI window is within the aforementioned listenable positions "SFNstart, slotstart, SFNend, slotend", then the terminal device will start listening to SI messages from time slot #a in the SFN radio frame. Where a = x mod N.

[0408] As an example, in an NTN scenario, one physical beam serves 8 cells (or wavelet clusters, wavelets, etc.) in a time-division multiplexing manner. The SSB period is 160ms. Within the first SSB period, cell 1 (or wavelet cluster 1, wavelet 1, etc.) serves for 1-20ms, cell 2 (or wavelet cluster 2, wavelet 2, etc.) serves for 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots within a radio frame (i.e., N is 10), si-Periodicity is configured as sf16 (i.e., 16 radio frames, T is 16), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5). A second offset is configured so that the starting position of the SI window is within the cell's service time. For example, the value of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is 0, the value of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is 20, the value of cell 3 (or wavelet cluster 3, wavelet 3, etc.) is 40, the value of cell 4 (or wavelet cluster 4, wavelet 4, etc.) is 60, the value of cell 5 (or wavelet cluster 5, wavelet 5, etc.) is 80, the value of cell 6 (or wavelet cluster 6, wavelet 6, etc.) is 100, the value of cell 7 (or wavelet cluster 7, wavelet 7, etc.) is 120, and the value of cell 8 (or wavelet cluster 8, wavelet 8, etc.) is 140.

[0409] Under this configuration, taking cell 1 (or wavelet cluster 1, wavelet 1, etc.) as an example, the range of the listening window is: SFNstart=0, slotstart=0, SFNend=1, slotend=5. Then, cell 1 (or wavelet cluster 1, wavelet 1, etc.) can listen to the 1st, 2nd, and 3rd SI windows within one SI cycle.

[0410] For example, a schematic diagram of the SI window of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is shown in Figure 3g.

[0411] In this embodiment of the disclosure, by configuring a second offset and an SI message listening duration, the second offset can indicate the interval between each SI window and the starting position or the end of the previous SI window, and the SI message listening duration can indicate the duration of the current SI listening. The terminal device determines a listening window based on the second offset and the SI message listening duration to listen for SI messages falling within the listening window, thereby ensuring the reliability of the communication process.

[0412] Option 7: Configuration parameters include the listening window period corresponding to the SI listening window, the second offset, and the SI message listening length.

[0413] In some embodiments, within the same listening window period, the interval between the starting positions of the SI window of different cells (or bands, bands) belonging to the same physical beam time-division service is indicated by a second offset; for a cell in different listening window periods within the same SI period, the starting position of the SI window listening is spaced apart by several listening window period values, and the SI message listening length is used to indicate the duration of listening to SI messages within the current listening window period. The SI message listening duration is determined based on the transition pattern information, and the value of the SI message listening duration is less than or equal to the service duration of the beam.

[0414] In this embodiment of the disclosure, the name of the listening window period is not limited. For example, in some scenarios, "listening window period" can be interchanged with "listening window period" or "window period".

[0415] For network devices, in some embodiments, the listening window period and the second offset are obtained based on beam hopping pattern information, the window length of the SI window, the order of the SI scheduling information entries in the scheduling information list, and a first value. The first value is obtained based on the starting position information, the transmission period of the SI message, and the number of time slots within the radio frame.

[0416] In some embodiments, the second offset represents the time slot offset between the starting position of the first SI window and the starting point of the system frame. The network device can configure the second offset according to the beam hopping pattern information to adjust the number of time slots that need to be spaced between the first SI window and the starting position of the beam service, so that the starting position of the SI window is within the service time of the serving beam.

[0417] In some embodiments, when configuring the second offset, the network device includes the following steps S21 to S22:

[0418] S21. Determine the first value based on the starting position information, the transmission period of the SI message, and the number of time slots in the radio frame.

[0419] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0420] S22. Determine the second offset based on the beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and the first value.

[0421] In some embodiments, the second offset also satisfies the following formula (8): x = FLOOR((n-1) / k) × T S +offset+i×w (8)

[0422] Where x is the first value, offset is the second offset, n is the order of SI scheduling information entries in the scheduling information list (or schedulingInfoList); w is the window length of the SI window (or si-WindowLength); Ts is the listening window period, which is configured by the network device at the granularity of SI window, slot, or radio frame; duration is the SI message listening duration; i is the third value; and k is the second value.

[0423] In some embodiments, i is a first variable parameter, indicating the number of SI windows that have been monitored within the current monitoring window; k is a second variable parameter, indicating the number of SI windows that can be monitored within a monitoring window, where i = (n-1) mod k, k = duration / w. The (k+1)th SI window will not appear until the next monitoring window period.

[0424] In Scheme 7, for the terminal device, in some embodiments, the starting position information is obtained based on the SI message transmission period, the number of time slots in the radio frame, and a first value; the first value is obtained based on a third part, a second offset, and a fourth part; the third part is obtained based on the listening window period, the second value, and the order of SI scheduling information entries in the scheduling information list; the fourth part is obtained based on the SI window length and a third value; the second value is obtained based on the SI message listening duration and the SI window length; and the third value is obtained based on the second value and the order of SI scheduling information entries in the scheduling information list.

[0425] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S23 to S24 are included:

[0426] S23. Determine the third part based on the listening window period, the second value, and the order of SI scheduling information entries in the scheduling information list; determine the fourth part based on the SI window length and the third value; determine the third value based on the second value and the order of SI scheduling information entries in the scheduling information list; determine the first value based on the third part, the second offset, and the fourth part; determine the starting position information based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0427] In some embodiments, the terminal device may determine the first value x according to the above formula (8).

[0428] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0429] S24. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0430] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0431] In this embodiment of the disclosure, the SI window starts from time slot #a in the SFN, where a = x mod N. As an example, in an NTN scenario, one physical beam serves 8 cells (or wavelet clusters, wavelets, etc.) in a time division, and the SSB period TSSB is 160ms. In the first SSB period, the service time of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is 1-20ms, the service time of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf32 (i.e., 32 radio frames, T is 32), si-WindowLength is configured as s5 (i.e., 5 slots, w is 5); the listening window period TS is configured as s160 (160 slots), the SI message listening duration is s10 (10 slots), and the second offset is 5.

[0432] Taking cell (or wavelet cluster 1, wavelet 1, etc.) as an example, the terminal device calculates the position of the SI window according to the above configuration. When k=2 (that is, within one listening window period, the terminal device can listen to 2 SI windows), for example, the schematic diagram of the SI window of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is shown in Figure 3h.

[0433] In this embodiment of the disclosure, by configuring the listening window period, the second offset, and the listening duration of the SI window for the terminal device, each cell (or band cluster, band) can determine the starting position of the SI window using the listening window period, the second offset, and the listening duration of the SI window. Then, the SFN at the beginning of the SI window is matched with the starting SFN of the beam serving the cell (or band cluster, band). The SI message is listened to in the SI window according to the SI message listening duration, so that the SI message can be accurately listened to, thereby ensuring the reliability of the communication process.

[0434] Option 8: The configuration parameters include the second and third parameters.

[0435] In some embodiments, the second parameter is used to indicate the number of continuously monitored SI windows, and the third parameter is used to indicate the number of skipped monitored SI windows.

[0436] In some embodiments, every s consecutive SI windows, the satellite beam can provide sufficient service time for one SI, and no service is provided after an interval of k SI windows. Here, s is a second parameter, and k is a third parameter. s and k can be configured by network devices or obtained based on SSB periodic mapping. A different k value is configured for each s SI window, or k can be a fixed value that can be used for all SIs. For example, k0 is a cell-level (or band-cluster-level, band-position-level) parameter, and for a cell (or band-cluster, band-position), the starting position is fixedly offset by k0 SI windows.

[0437] In some embodiments, when the network device determines the second parameter s and the third parameter k based on the beam hopping pattern, the second parameter s and the third parameter k satisfy the following condition:

[0438] The product of s and w is less than or equal to the beam dwell time (i.e., s × w is less than or equal to the beam dwell time);

[0439] The product of k and w is the difference between the beam period and the product of s and w (i.e., k × w = beam period - s × w).

[0440] In some embodiments, for network devices, the second parameter s and the third parameter k are obtained based on beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and a first value. The first value is obtained based on the starting position information, the transmission period of the SI message, and the number of time slots within the radio frame.

[0441] In some embodiments, when configuring the first parameter and the second parameter, the network device includes the following steps S25 to S26:

[0442] S25. Determine the first value based on the starting position information, the transmission period of the SI message, and the number of time slots in the radio frame.

[0443] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0444] S26. Determine the second and third parameters based on the beam hopping pattern information, the window length of the SI window, the order of SI scheduling information entries in the scheduling information list, and the first value.

[0445] In some embodiments, the second parameter s and the third parameter k also satisfy the following formula (9):

[0446] Where s is the first parameter; k is the third parameter; n is the order of SI scheduling information entries in the scheduling information list (or schedulingInfoList); and w is the window length of the SI window (or si-WindowLength).

[0447] In Scheme 8, for the terminal device, in some embodiments, the starting position information of the SI window is obtained based on the transmission period of the SI message, the number of time slots within the radio frame, and a first value. Specifically, the first value is obtained based on the fifth, sixth, and seventh parts; the fifth part is obtained based on the order of the SI scheduling information entries in the scheduling information list, the second parameter, and the window length of the SI window; the sixth part is obtained based on the order of the SI scheduling information entries in the scheduling information list, the second parameter, and the third parameter; and the seventh part is obtained based on the order of the SI scheduling information entries in the scheduling information list, the second parameter, and the window length of the SI window.

[0448] The fifth part is (n–1) mod s) × w; the sixth part is The seventh part is FLOOR((n-1) / s)×s×w.

[0449] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S27 to S28 are included:

[0450] S27. Determine the first value according to Part 5, Part 6 and Part 7.

[0451] In some embodiments, the terminal device may determine the first value x according to the above formula (9).

[0452] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0453] S28. Determine the starting position information of the SI window based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0454] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0455] In this embodiment of the disclosure, the SI window starts from time slot #a in the SFN, where a = x mod N. As an example, in an NTN scenario, one physical beam serves 8 cells (or wavelet clusters, wavelets, etc.) in a time division, and the SSB period TSSB is 160ms. In the first SSB period, the service time of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is 1-20ms, the service time of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots in a radio frame (i.e., N is 10), si-Periodicity is configured as sf32 (i.e., 32 radio frames, T is 32), si-WindowLength is configured as s5 (i.e., 5 slots, w is 5); the listening window period TS is configured as s160 (160 slots), the SI message listening duration is s10 (10 slots), the second offset is 5, and the second parameter s is configured as 4.

[0456] In this scenario, if we want SI monitoring for each cell (or bandgap, bandgap, etc.) to start from the beam service start time, then k0 for cell 1 (or bandgap cluster 1, bandgap 1, etc.) is configured to 0, k0 for cell 2 (or bandgap cluster 2, bandgap 2, etc.) is configured to 4, k0 for cell 3 (or bandgap cluster 3, bandgap 3, etc.) is configured to 8, and so on. i This represents the number of windows between the first SI listening window and the next SI listening window after every s SI windows. Under the above system configuration, k can be configured. i The value is fixed at 28. The SI scheduling of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is shown in Figure 3i.

[0457] In this embodiment of the disclosure, by configuring the second and third parameters for the terminal device, each cell (or band cluster, band position) can determine the starting position of the SI window using the listening window period, the second offset, and the listening duration of the SI window. Then, the SFN at the beginning of the SI window is matched with the starting SFN of the beam serving the cell (or band cluster, band position), and the SI message is listened to in the SI window according to the SI message listening duration. The SI message can be accurately listened to, thereby ensuring the reliability of the communication process.

[0458] Option 9: The configuration parameters include the first configuration parameter and the second configuration parameter.

[0459] In some embodiments, the first configuration parameter is used to indicate that the length of the SI window is configured as an integer multiple of the SSB period, and the SI period is configured as an integer multiple of the SSB period; the second configuration parameter is used to indicate other system information OSI search spaces for listening to SI messages.

[0460] That is, in this embodiment of the disclosure, the length of the SI window can be configured to be an integer multiple of the SSB period, the SI period can be configured to be an integer multiple of the SSB period, and the listening windows of different cells (or band clusters, bands) under the same physical beam can be finely configured using the search space other system information (OSI search space).

[0461] In some embodiments, the second configuration parameters include the monitoring slot periodicity parameter, the second offset, and the SI message listening duration.

[0462] The network device can configure the SI message listening duration based on the beam transition pattern information. The SI message listening duration is less than or equal to the service duration of the beam. The network device can also configure a second offset based on the beam transition pattern information to adjust the number of time slots required between the first SI window and the starting position of the beam service, or between adjacent windows, ensuring that the starting position of the SI window falls within the service time of the serving beam.

[0463] In some embodiments, as an example, in an NTN scenario, one physical beam serves 8 cells (or beam clusters, beams, etc.) in a time division, and the SSB period TSSB is 160ms. In the first SSB period, the service time of cell 1 (or beam cluster 1, beam 1, etc.) is 1-20ms, the service time of cell 2 (or beam cluster 2, beam 2, etc.) is 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots within a radio frame (i.e., N is 10), si-Periodicity is configured as sf32 (i.e., 32 radio frames, T is 32), si-WindowLength is configured as s160 (i.e., 160 slots, w is 160); the listening window period TS is configured as s160 (160 slots); in the OSI search space (i.e., searchSpaceOtherSystemInformation), the monitoring slot periodicity parameter (i.e., monitoringSlotPeriodicityy) is configured as sl160 (i.e., 160 slots), the second offset (i.e., offset) is configured differently according to different cells / wavelength clusters / wavelengths, and the SI message listening length (i.e., duration) is configured as 5 (5 slots).

[0464] For example, for offset configuration, cell 1 (or wavelet cluster 1, wavelet 1, etc.) is configured as 0, cell 2 (or wavelet cluster 2, wavelet 2, etc.) is configured as 20, and so on. The SI scheduling diagram for cell 1 (or wavelet cluster 1, wavelet 1, etc.) is shown in Figure 3j.

[0465] Option 10: Configuration parameters include the fourth parameter.

[0466] In some embodiments, the fourth parameter is used to indicate the position of the SI window.

[0467] In some embodiments, the si-WindowPosition (i.e., the fourth parameter) parameter from schedulingInfoList2 can be introduced into schedulingInfoList to replace n in the SI window start position.

[0468] In some embodiments, the range of the fourth parameter is (1…256), and the fourth parameter is different for each SI message, which is equivalent to being able to directly configure the terminal device to start SI listening from which window position.

[0469] In some embodiments, for network devices, the fourth parameter is obtained based on beam hopping pattern information, the window length of the SI window, and a first value. The first value is obtained based on start position information, the SI message transmission period, and the number of time slots within a radio frame. The fourth parameter (i.e., si-WindowPosition) indicates the actual position of the SI window to be monitored, in the order in which SI windows are arranged starting from the start position of the system frame.

[0470] In some embodiments, when configuring the fourth parameter, the network device includes the following steps S29 to S30:

[0471] S29. Determine the first value based on the starting position information, the transmission period of the SI message, and the number of time slots in the radio frame.

[0472] In some embodiments, the first value x can be determined according to formula (3) in Scheme 2 above.

[0473] S30. Determine the fourth parameter based on the beam hopping pattern information, the window length of the SI window, and the first value.

[0474] In some embodiments, the fourth parameter satisfies the following formula (10): x=(si-WindowPosition-1)×w (10)

[0475] Where si-WindowPosition is the fourth parameter; w is the window length of the SI window.

[0476] In Scheme 10, for the terminal device, in some embodiments, the starting position information is obtained based on the SI message transmission period, the number of time slots within the radio frame, and a first value. The first value is obtained based on a fourth parameter and the window length of the SI window.

[0477] In some embodiments, when the terminal device determines the location information of the SI window based on the configuration parameters in the SI scheduling information, the following steps S31 to S32 are included:

[0478] S31. Determine the first value x based on the fourth parameter and the window length of the SI window.

[0479] In some embodiments, the first value x can be determined according to the above formula (10).

[0480] Among them, the order of SI scheduling information entries in the scheduling information list is n (or schedulingInfoList); the window length w (or si-WindowLength) of the SI window can also be indicated to the terminal device by the network device through the SI scheduling information.

[0481] S32. Determine the starting position information based on the SI message transmission period, the number of time slots in the radio frame, and the first value.

[0482] In some embodiments, the terminal device determines the SFN (i.e., the starting position information of the SI window) according to formula (3) in the above scheme 2.

[0483] The SI window starts from slot #a in SFN, where a = x mod N.

[0484] In this embodiment of the disclosure, as an example, in an NTN scenario, one physical beam serves 8 cells (or wavelet clusters, wavelets, etc.) in a time-division multiplexing manner. The SSB period (TSSB) is 160ms. During the first SSB period, the service time of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is 1-20ms, the service time of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is 21-40ms, and so on. Assuming SCS = 15kHz, there are 10 time slots in a radio frame (i.e., N is 10), and si-WindowLength is configured as s5 (i.e., 5 slots, w is 5). Each cell (or wavelet cluster, wavelet, etc.) contains 1 SI message, i.e., 1 SI window. Therefore, the si-WindowPosition of cell 1 (or wavelet cluster 1, wavelet 1, etc.) is configured as 1, the si-WindowPosition of cell 2 (or wavelet cluster 2, wavelet 2, etc.) is configured as 5, and so on. SI scheduling is shown in Figure 3k below.

[0485] In this embodiment of the disclosure, by configuring a fourth parameter for the terminal device, each cell (or band cluster, band position) can determine the starting position of the SI window using the listening window period, the second offset, and the listening duration of the SI window. Then, the SFN at the beginning of the SI window is matched with the starting SFN of the beam serving the cell (or band cluster, band position), and the SI message is listened to in the SI window according to the SI message listening duration. The SI message can be accurately listened to, thereby ensuring the reliability of the communication process.
