[0120] FIG. 1B is a schematic diagram of a scenario of an NTN. As shown in FIG. 1B, in an NTN network, the terminal calculates T TA As follows: T TA= Service Link RTT + Common TA. Wherein, Service Link RTT is a service link round-trip time (RTT), the value of which can be calculated by the terminal according to its own position and the position of the satellite; Common TA is provided by the network device, and the value thereof is used to indicate the RTT between the uplink reference point RP and the satellite; Feedback Link RTT is the RTT between the satellite and the network device; K mac is the RTT between the network device and the uplink and downlink reference points.

[0121] Since the Service Link RTT is calculated by the terminal itself, the network device does not know it. However, in order to ensure that the time domain position of scheduling is after the time when the terminal receives the scheduling information, the network device needs to know the TA value of the terminal in order to perform scheduling. Therefore, the 3rd Generation Partnership Project (3GPP) introduces TA reporting. If the terminal has not reported the TA before, or the TA change value is greater than a certain threshold, the terminal needs to report the TA. FIG. 1C is a schematic diagram of a TA reporting format. Wherein, Oct1 is the first octet in the media access control (MAC) control element (controlElement, CE), Oct2 is the second octet in the MAC CE, and R is a reserved bit.

[0122] FIG. 1D is a schematic diagram of a carrier aggregation scenario network of an NTN.

[0123] As shown in FIG. 1D, in the carrier aggregation scenario, the primary cell (PCell) can adopt satellite 1 (such as a high-orbit satellite) to provide large coverage, and other secondary cells (SCell) except the special cell (SpCell) can adopt satellite 2 (such as a low-orbit satellite) to provide high speed. The PCell and the SCell perform carrier aggregation through a satellite transmittal mode, that is, the NTN ground station can transmit the signals of the gNB to satellite 1 and satellite 2 through the transmittal mode respectively. Wherein, the SpCell refers to the PCell and the primary secondary cell (PSCell). In this scenario, the TA of each cell is different.

[0124] In some embodiments, when the PCell adopts one satellite and the PSCell adopts another satellite, that is, in dual connectivity (DC), the TA of each cell is also different.

[0125] The information sending method and apparatus provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0126] FIG. 2A is an interaction schematic diagram of an information sending method according to an embodiment of the present disclosure. As shown in FIG. 2A, the present embodiment relates to an information sending method, and the method comprises:

[0127] In step S2101, the terminal 101 determines whether a TA reporting condition is met.

[0128] In some embodiments, the terminal 101 is a non-terrestrial network (NTN) terminal, and the network device is an NTN device.

[0129] In some embodiments, the terms “non-terrestrial network”, “non-terrestrial network”, “non-terrestrial communication”, “non-terrestrial communication” and the like can be replaced with each other.

[0130] In some embodiments, the terminal 101 is in a carrier aggregation (CA) and / or dual connectivity (DC) scenario. That is, the terminal 101 needs to report the TA values corresponding to multiple cells or multiple TAGs.

[0131] In some embodiments, the TA reporting condition can be that there is one or more unreported TA in the serving cell and / or the time advance group (TAG) of the terminal.

[0132] In some embodiments, the TA reporting condition can also be that there is one or more TA with a change amount greater than a threshold value in the serving cell and / or the TAG of the terminal.

[0133] In some embodiments, for the serving cell, the change amount refers to the change amount of the new TA value corresponding to the serving cell compared with the last reported TA value of the serving cell.

[0134] In some embodiments, for the TAG, the change amount refers to the change amount of the new TA value corresponding to the TAG compared with the last reported TA value.

[0135] In some embodiments, the threshold value can be agreed upon by the protocol or indicated by the network device 102, which is not limited in the present disclosure.

[0136] In some embodiments, the TA reporting condition can also be that the terminal receives a reconfiguration threshold value.

[0137] In some embodiments, the reconfiguration threshold can be a threshold value configured by the network device to trigger TA reporting. When a certain TA value is greater than this value, the terminal 101 needs to report the TA value.

[0138] In some embodiments, the reconfiguration threshold can be configured per Bandwidth Part (BWP), or per serving cell, or per tag, or per Master Cell Group (MCG), or per Secondary Cell Group (SCG), or per UE.

[0139] Step S2102: If the reporting conditions are met, terminal 101 determines the TA report format.

[0140] In some embodiments, the TA report can be in the format of a single entry or multiple entries.

[0141] In some embodiments, terms such as "single entry," "single record," "single item," "single data," and "single information" can all indicate that each TA value in a TA report is relatively independent and has no direct correlation. In some cases, the above terms can be used interchangeably.

[0142] In some embodiments, terms such as "multiple entries," "multiple records," "multiple items," "multiple data," and "multiple information" can all indicate that data points or entries in a TA report are organized into multiple groups or categories, each group or category containing a series of related entries. In some cases, these terms can be used interchangeably. Using a multiple entry format may mean that the timing lead of network devices, cells, or TAGs is grouped according to certain rules (such as geographical location, service type, etc.) and presented separately in the report.

[0143] In some embodiments, terminal 101 may determine the format of the TA report based on the relationship between the TA values ​​to be reported.

[0144] In some embodiments, if terminal 101 needs to report the TA value corresponding to any of the following, then the format of the TA report can be determined as a single entry: primary cell, primary and secondary cell, TAG corresponding to primary cell, and TAG corresponding to primary and secondary cell.

[0145] In some embodiments, if the terminal 101 needs to report TA values of more than one cell or more than one TAG, the terminal 101 determines the format of the TA report to be multiple entries: primary cell, primary secondary cell, TAG corresponding to the primary cell, and TAG corresponding to the primary secondary cell.

[0146] In some embodiments, if the terminal 101 needs to report TA values of one cell or one TAG, the terminal 101 determines the format of the TA report to be a single entry.

[0147] In some embodiments, if the terminal 101 needs to report TA values of more than one cell and / or more than one TAG, the terminal 101 determines the format of the TA report to be multiple entries.

[0148] In the above embodiments, if the terminal 101 needs to report only a small number of TA values (for example, only the TA value of the primary cell), the terminal 101 can use a single entry TA report to simplify the difficulty of reading the TA report by the network device and improve the efficiency of TA reporting. If multiple TA values need to be reported, the terminal 101 can use a multiple entry TA report to group and report multiple TA values, thereby minimizing the size of the TA report while simplifying the difficulty of reading the TA report by the network device and improving the efficiency of TA reporting.

[0149] In some embodiments, the single entry TA report can include at least one of the following: cell index and TA value; cell index, reserved bit (R), and TA value; TAG index (TAG) and TA value; TAG index, reserved bit, and TA value.

[0150] FIG. 2B is a schematic diagram of a single entry TA report format provided by the present disclosure. As shown in (1) of FIG. 2B, the TA report can include only a cell index and a Timing Advance. Alternatively, as shown in (2) of FIG. 2B, the TA report can include a cell index, a reserved bit (R), and a Timing Advance. Alternatively, as shown in (3) of FIG. 2B, the TA report can include a TAG and a Timing Advance. Alternatively, as shown in (4) of FIG. 2B, the TA report can include a TAG, a reserved bit (R), and a Timing Advance.

[0151] The cell index and the TAG index can each occupy a different number of bits as needed. For example, the cell index can occupy 1-8 bits, the TAG index can occupy 1-4 bits, and so on. In addition, the number of bits occupied by the R can also be set as needed, and the present disclosure does not limit this.

[0152] In some embodiments, the multi-entry TA report includes at least one of: a first indication information bitmap, wherein each bit in the first indication information bitmap indicates whether the TA value of the cell associated with the bit is included in the TA report; and a second indication information bitmap, wherein each bit in the second indication information bitmap indicates whether the TA value of the TAG associated with the bit is included in the TA report.

[0153] In some embodiments, one bit in the first indication information bitmap is associated with one cell. The association between the bit and the cell can be determined by a protocol or indicated by the network device.

[0154] In some embodiments, one bit in the second indication information bitmap is associated with one TAG. The association between the bit and the TAG can be determined by a protocol or indicated by the network device.

[0155] FIG. 2C is a schematic diagram of a multi-entry TA report format provided by the present disclosure. As shown in (1) of FIG. 2C, the TA report can include only the first indication information bitmap, the reserved bit R, and the TA values corresponding to different cells (such as c i , c k , c j ). Wherein, c i represents the ith cell i, i, j, k are natural numbers, and N is the number of eight-bit groups included in the TA report, which is related to the number of reported TA values.

[0156] As shown in the first (or second) indication information bitmap of FIG. 2C, the value of the indication bit associated with each cell (or TAG) can be used to indicate whether the TA value of the cell (or TAG) is included in the TA report. For example, the value of a certain indication bit is “1” indicating that the TA value of the cell (or TAG) is included in the TA report, and the value of a certain indication bit is “0” indicating that the TA value of the cell (or TAG) is not included in the TA report; or the value of a certain indication bit is “0” indicating that the TA value of the cell (or TAG) is included in the TA report, and the value of a certain indication bit is “1” indicating that the TA value of the cell is not included in the TA report, and the like. The present disclosure does not limit the specific indication method for indicating whether the TA value of the corresponding cell (or TAG) is included in the TA report.

[0157] In some embodiments, the size of the first bit map can be, for example, 4, 8, 16, 32, and the like. It can be located at the beginning of the MAC CE. The size of the TA value can be 8 bits, or 16 bits, or 14 bits, and the like. If the number of bits is not enough for a whole byte, the remaining bits can be set as R bits. The R bits can be located in front of or behind the TA value bits.

[0158] In some embodiments, as shown in (2) of FIG. 2C, the TA report can only include the second indication information bitmap, the reserved bit R, and the TA value corresponding to the different TAG (such as c i , c k , c j ). Wherein, c i represents the i-th TAG, i, j, k are natural numbers, and N is the number of octets included in the TA report, which is related to the number of reported TA values.

[0159] In some embodiments, the size of the second bit map can be, for example, 2, 3, 4, 8. The second bit map can be located at the beginning of the MAC CE. The second bit map that is less than 8 bits can be padded by the R bits, or part of the bits of the TA value. In addition, the R bits can be located in front of or behind the 8 bits. The size of the TA value can be 8 bits, or 16 bits, or 14 bits, etc.

[0160] In some embodiments, the position of the reserved bit can be adjusted as needed, such as shown in (3) of FIG. 2C.

[0161] In the embodiments of the present disclosure, the terminal 101 can select a format of TA report from multiple forms of Single Entry or Multiple Entry according to needs, to report the TA values of multiple cells and / or multiple TAGs, thereby improving the flexibility of TA reporting.

[0162] In some embodiments, different TA report formats can correspond to different reporting conditions. Therefore, the terminal can determine the format of the TA report according to the conditions met.

[0163] In step S2103, the terminal 101 sends the TA report to the network device 102.

[0164] In some embodiments, the TA report includes the TA values of multiple serving cells and / or multiple TAGs.

[0165] In some embodiments, if the TA report is triggered by any of the following: cell switching, connection establishment, connection recovery, connection re-establishment, the TA report can only include the TA value of the primary cell.

[0166] In the embodiments of the present disclosure, if the TA report is only triggered by cell switching or connection change, the terminal can only report the TA value of the primary cell, thereby minimizing the uplink transmission, and providing conditions for the network device to perform accurate scheduling.

[0167] In some embodiments, in the dual connectivity scenario, the terminal 101 can send a TA report containing the TA value of the primary cell group to the first network device corresponding to the primary cell group, and send a TA report containing the TA value of the secondary cell group to the second network device corresponding to the secondary cell group.

[0168] In the embodiments of the present disclosure, in the dual connectivity scenario, the terminal 101 can report the TA value of the MCG to the MCG only, and report the TA value of the SCG to the SCG, thereby providing conditions for reliable scheduling of the MCG and the SCG, respectively.

[0169] In some embodiments, if one or more serving cells, or one or more TAGs, trigger the TA report, the TA report can include at least one of the following: the TA value of the serving cell and / or the TAG that triggers the TA report; the TA value of all serving cells in the cell group corresponding to the serving cell and / or the TAG that triggers the TA report; the TA value of all serving cells and / or TAGs in the primary cell group and the secondary cell group; the TA value of part of the serving cells in the cell group corresponding to the serving cell and / or the TAG that triggers the TA report; and the TA value of part of the serving cells and / or TAGs in the primary cell group and the secondary cell group.

[0170] For example, the terminal 101 can report only the changed TA value of Cell#1 if the TA change value of Cell#1 is greater than the threshold value and triggers the TA report.

[0171] Alternatively, the terminal 101 can report the TA value of each cell in the cell group (Cell Group) to which Cell#1 belongs if the TA change value of Cell#1 is greater than the threshold value and triggers the TA report. For example, Cell#1 belongs to the MCG, and the MCG includes Cell#1 and Cell#2, and the terminal can report the current TA values corresponding to Cell#1 and Cell#2, respectively.

[0172] Alternatively, the terminal 101 can report only the TA value of Cell#1 if the TA change value of Cell#1 is greater than the threshold value and triggers the TA report, Cell#1 belongs to the MCG, and the MCG includes Cell#1, Cell#2, and Cell#3. Alternatively, the terminal 101 can report the current TA values corresponding to Cell#1 and Cell#2, respectively, or the current TA values corresponding to Cell#1 and Cell#3, respectively, and so on.

[0173] In some embodiments, the terminal 101 can determine the number of TA values of part of the serving cells included in the TA report according to the amount of uplink resources.

[0174] In the embodiments of the present disclosure, the terminal 101 needs to send a TA report using uplink (UP) resources. The amount of uplink resources currently available to the terminal 101 can not be able to carry too many TA values. Therefore, the terminal 101 can report only part of the TA values according to the amount of available uplink resources, thereby providing a basis for reliable scheduling of the network device 102.

[0175] In some embodiments, the part of the serving cells can include the serving cell and / or the TAG that triggers the TA report.

[0176] That is, the terminal 101 can report only the TA value of the serving cell and / or the TAG that triggers the TA report, thereby ensuring that the changed TA value can be reliably sent to the network device 102.

[0177] In some embodiments, the amount of resources of the uplink resources is greater than the amount of resources occupied by the TA value of the serving cell and / or the TAG that triggers the TA report. Then, the part of the serving cells in the TA report can further include the TA value of at least one other serving cell and / or TAG, wherein the at least one other serving cell and / or the TAG belongs to the same cell group as the serving cell and / or the TAG that triggers the TA report.

[0178] That is, if the uplink resources can accommodate other TA values in addition to the TA of the cell / TAG that triggers the TA report, the terminal 101 can further carry the TA of the other one or more serving cells and / or TAGs in the same cell group in the TA report.

[0179] For example, the cell that triggers the TA report is Cell#1, the amount of resources occupied by the TA value of Cell#1 is less than the amount of uplink resources currently available to the terminal, and Cell#2, Cell#3, and Cell#4 belong to the same cell group as Cell#1. Then, the terminal can report the TA values of Cell#1 and Cell#2, or the TA values of Cell#1 and Cell#3, or the TA values of Cell#1 and Cell#4, or the TA values of Cell#1 and Cell#2 and Cell#3, and so on, through the TA report.

[0180] In some embodiments, if the cells and / or the TAGs corresponding to the multiple TA values to be reported by the terminal belong to the same cell group, the same MAC CE can be used to send the TA report, and the TA report can be sent to the network device corresponding to the primary cell and / or the primary secondary cell.

[0181] In some embodiments, if the multiple TA values to be reported by the terminal correspond to cells and / or TAGs belonging to different cell groups, the TA values corresponding to different cell groups can be sent using different MAC CEs.

[0182] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2103. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, steps S2101+S2103 can be implemented as an independent embodiment, steps S2102+S2103 can be implemented as an independent embodiment, and the like, but are not limited thereto.

[0183] In the present embodiment or example, each step can be independent, arbitrarily combined, or the order can be exchanged without contradiction, and optional modes or optional examples can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0255] FIG. 5B is a flow diagram of a method according to an embodiment of the present disclosure. As shown in FIG. 5B, the method according to an embodiment of the present disclosure is used for the terminal 101, and the method includes the following steps.

[0256] In step 5201, the format of the TA report is determined.

[0257] In some embodiments, the format of the TA report can be single entry (Single Entry) or multiple entry (Multiple Entry).

[0258] In some embodiments, the terms “single entry”, “single record”, “single item”, “single data”, “single information”, and the like can all indicate that each TA value in a TA report is relatively independent and has no direct correlation. In some cases, the above terms can be replaced with each other.

[0259] In some embodiments, the terms "multiple entry", "multiple record", "multiple item", "multiple data", "multiple information", and the like, can all indicate that the data points or entries in a TA report are organized into multiple groups or categories, each group or category containing a series of related entries. In some cases, the above terms can be replaced with each other. If the multiple entry format is adopted, it can mean that the time advance of the network device, cell or TAG is grouped according to certain rules (such as geographical location, service type, etc.) and presented separately in the report.

[0260] In some embodiments, the terminal 101 can determine the format of the TA report according to the relationship of the TA values that need to be reported.

[0261] In some embodiments, if the terminal 101 needs to report the TA value corresponding to a serving cell or a TAG, the TA report can adopt a single entry format.

[0262] In some embodiments, if the terminal 101 needs to report the TA value corresponding to a primary cell or a primary secondary cell, the TA report can adopt a single entry format.

[0263] In some embodiments, if the terminal 101 needs to report the TA value of the TAG corresponding to a primary cell or a primary secondary cell, the TA report can adopt a single entry format.

[0264] In some embodiments, if the terminal 101 needs to report TA values other than the following, or report TA values of multiple cells or multiple TAGs, the format of the TA report is determined to be multiple entries: primary cell, primary secondary cell, TAG corresponding to the primary cell, and TAG corresponding to the primary secondary cell.

[0265] That is, if the TA values to be reported by the terminal 101 do not belong to the primary cell and / or the primary secondary cell, or are not the TA values of the TAG corresponding to the primary cell and / or the primary secondary cell, the terminal can adopt a TA report in multiple entry format.

[0266] In some embodiments, if the terminal 101 needs to report TA values of multiple serving cells and / or multiple TAGs, the TA report can adopt a multiple entry format.

[0267] In some embodiments, if the cells and / or TAGs corresponding to the multiple TA values to be reported by the terminal belong to the same cell group, the same MAC CE can be used to send the TA report, and the TA report can be sent to the network device corresponding to the primary cell and / or the primary secondary cell.

[0268] In some embodiments, if the cells and / or TAGs corresponding to the multiple TA values to be reported by the terminal belong to different cell groups, the TA values corresponding to different cell groups can be sent using different MAC CEs.

[0269] In some embodiments, if the terminal 101 only needs to report a small amount of TA values (such as only reporting the TA value of the primary cell), a single entry format TA report can be used. Thus, the difficulty of reading the TA report by the network device is simplified, and the efficiency of TA reporting is improved. If multiple TA values need to be reported, a multiple entry format TA report can be used, and multiple TA values are reported in groups, so as to minimize the size of the TA report while simplifying the difficulty of reading the TA report by the network device and improving the efficiency of TA reporting.

[0270] In some embodiments, as shown with reference to FIG. 2B: at least one of the following can be included in the single entry TA report: cell index and TA value; cell index, reserved bit (R), and TA value; TAG index (TAG) and TA value; TAG index, reserved bit, and TA value.

[0271] As shown in (1) of FIG. 2B, the TA report can only include the cell index and the Timing Advance. Or as shown in (2) of FIG. 2B, the TA report can include the cell index, the reserved bit (R), and the Timing Advance. Or as shown in (3) of FIG. 2B, the TA report can include the TAG and the Timing Advance. Or as shown in (4) of FIG. 2B, the TA report can include the TAG, the reserved bit (R), and the Timing Advance.

[0272] The cell index and the TAG index can occupy different numbers of bits as needed, respectively. For example, the cell index can occupy 1-8 bits, the TAG index can occupy 1-4 bits, and so on. In addition, the number of bits occupied by R can also be set as needed, which is not limited in the present disclosure.

[0273] In some embodiments, the multiple entry TA report includes at least one of the following: a first indication information bitmap, wherein each bit in the first indication information bitmap is used to indicate whether the TA report contains the TA value of the cell associated with the bit; a second indication information bitmap, wherein each bit in the second indication information bitmap is used to indicate whether the TA report contains the TA value of the TAG associated with the bit.

[0274] In some embodiments, one bit in the first indication information bitmap is associated with one cell. The association relationship between the bit and the cell can be agreed by the protocol or indicated by the network device.

[0275] In some embodiments, one bit in the second indication information bitmap is associated with one TAG. The association between the bit and the TAG can be determined by protocol or indicated by the network device.

[0276] As shown in (1) of FIG. 2C, the TA report can include only the first indication information bitmap, the reserved bits R, and the TA values corresponding to different cells (such as c i , c k , c j ). Here, c i represents the ith cell i, and i, j, and k are natural numbers. N is the number of eight-bit groups included in the TA report, which is related to the number of reported TA values.

[0277] In the first (or second) indication information bitmap shown in FIG. 2C, the value of the indicated bit associated with each cell (or TAG) can be used to indicate whether the TA value of the cell (or TAG) is included in the TA report. For example, the value of a certain indication bit is “1” to indicate that the TA value of the cell (or TAG) is included in the TA report, and the value of a certain indication bit is “0” to indicate that the TA value of the cell (or TAG) is not included in the TA report. Alternatively, the value of a certain indication bit is “0” to indicate that the TA value of the cell (or TAG) is included in the TA report, and the value of a certain indication bit is “1” to indicate that the TA value of the cell is not included in the TA report, and so on. The specific indication manner for indicating whether the TA value of the corresponding cell (or TAG) is included in the TA report is not limited in the present disclosure.

[0278] In some embodiments, the size of the first bit map can be, for example, 4, 8, 16, 32, and the like. It can be located at the beginning bit of the MAC CE. The size of the TA value is 8 bits, or 16 bits, or 14 bits, and the like. If the number is not an integer, the remaining bits can be set as R bits. The R bits can be located before or after the TA value bits.

[0279] In some embodiments, as shown in (2) of FIG. 2C, the TA report can include only the second indication information bitmap, the reserved bits R, and the TA values corresponding to different TAGs (such as c i , c k , c j ). Here, c i represents the ith TAG, and i, j, and k are natural numbers. N is the number of eight-bit groups included in the TA report, which is related to the number of reported TA values.

[0280] In some embodiments, the size of the second bit map can be, for example, 2, 3, 4, 8. The second bit map can be located at the beginning of the MAC CE. The second bit map with less than 8 bits can be padded with R bits, or part of the bits of the TA value. In addition, the R bits can be located before or after the 8 bits. The size of the TA value can be 8 bits, or 16 bits, or 14 bits, etc.

[0281] In some embodiments, the position of the reserved bit can be adjusted as needed, such as shown as (3) in FIG. 2C.

[0282] In the embodiments of the present disclosure, the terminal 101 can select a format of TA report from multiple formats of Single Entry or Multiple Entry as needed, to report the TA values of multiple cells and / or multiple TAGs, thereby improving the flexibility of TA reporting.

[0283] In some embodiments, different TA reporting formats can correspond to different reporting conditions. Thus, the terminal can determine the format of the TA report according to the satisfied condition.
