[0110] In some embodiments, due to large transmission delay in a satellite network (i.e., a Non-Terrestrial Network (NTN)), when performing uplink scheduling or downlink scheduling, the timing advance (TA) can be too large due to too long round-trip time (RTT), causing synchronization problems.

[0111] With the gradual utilization of available spectrum resources, the demand for simultaneously scheduling multiple cells / carriers will gradually increase. Simultaneously scheduling multiple cells / carriers can effectively improve the flexibility of intra-band / inter-band data scheduling and improve the corresponding power / spectrum efficiency. Therefore, when using downlink control information (DCI) to perform uplink scheduling / downlink scheduling, a multi-carrier (MC) scheduling method can be used to simultaneously schedule multiple cells in a single MC DCI.

[0112] For an NTN, in order to further improve the data rate to support video streaming services, a carrier aggregation (CA) method can also be used to improve the data rate through multi-carrier scheduling. In one CA scenario, multiple carriers of a terminal and the cells corresponding to the carriers come from different satellites. However, when multiple cells come from different satellites, the time delays generated by different satellites are different and can be large. In uplink scheduling / downlink scheduling using CA, the time of arrival of scheduling information is different, causing differences in scheduled resources.

[0113] FIG. 2 is an interaction diagram illustrating a data scheduling method according to an embodiment of the present disclosure.

[0114] As shown in FIG. 2, the data scheduling method includes:

[0115] In step S201, a time domain bias value is determined.

[0116] In some embodiments, when performing multi-carrier scheduling for satellite communication, the terminal can determine a time domain bias value to determine the time domain position of a first resource based on the time domain bias value, the first resource being a resource for uplink transmission and / or downlink transmission of the multi-carrier scheduling. The time domain bias value can be used to partially compensate for the delay generated by the communication between the terminal and the network device.

[0117] In some embodiments, when performing multi-carrier scheduling for satellite communication, the network device can determine a time domain offset value, to determine a time domain position of a first resource based on the time domain offset value, the first resource being a resource for uplink transmission and / or downlink transmission scheduled by the multi-carrier scheduling.

[0118] In some embodiments, the time domain offset value can include at least one of: a time domain offset value configured for each cell, a time domain offset value configured for a cell group in which each cell is located, and a difference between a time domain offset value between a scheduling cell and a scheduled cell. The scheduling cell is a cell in which the terminal receives information for scheduling uplink transmission and / or downlink transmission, and the scheduled cell is a cell in which the terminal transmits uplink transmission and / or receives downlink transmission.

[0119] The cell can be a Space-Air-Ground cell (SAN cell) corresponding to a satellite.

[0120] In some embodiments, the network device can determine the time domain offset values of different cells and / or cell groups, and send the time domain offset values of different cells and / or cell groups to the terminal. The time domain offset values can be determined in various ways. For example, the time domain offset values can be determined based on the TA of the cell and the TA of the cell group. The TA of the cell and the TA of the cell group can be calculated by the terminal or by the network device. The terminal can determine the TA according to ephemeris information and report the TA to the network device. The network device can determine the TA according to ephemeris information and / or the location of the terminal.

[0121] For example, the network device can determine the TA value required for data transmission between the terminal and the cell in which the satellite is located based on the location reported by the terminal and the ephemeris information of the satellite, and set the time domain offset value K offset of the cell based on the TA value corresponding to the cell, and send it to the terminal. Alternatively, the network device can broadcast the ephemeris information of the satellite to the terminal, the terminal can calculate the corresponding TA value according to the ephemeris information and report it to the network device, and the network device can configure the time domain offset value K offset of the cell in which the satellite is located, and send it to the terminal.

[0122] By configuring corresponding time domain offset values for each cell in satellite communication, when performing multi-carrier scheduling, the time delay that may be caused by the scheduled uplink transmission and / or downlink transmission can be compensated based on the time domain offset value, and the time domain position of the resource for the scheduled uplink transmission and / or downlink transmission can be accurately obtained.

[0123] In some embodiments, the network device can configure the terminal with the time domain offset value of each cell in various ways, for example, the time domain offset value of each cell can be carried by system signaling sent by the network device, such as a system information block (SIB), a medium access control control element (MAC CE), downlink control information, a first information, or the like.

[0124] In some embodiments, the time domain offset value of each cell can be broadcast in the SIB19 corresponding to each cell, and the time domain offset value can be updated by a MAC CE in each cell.

[0125] Step S202, the network device sends the first information from the first cell to the terminal.

[0126] In some embodiments, the network device can send the first information from the first cell to the terminal through a satellite network, and the first information can be used to schedule the first uplink transmission using multi-carrier scheduling and / or schedule the first downlink transmission using multi-carrier scheduling. Wherein, the first uplink transmission includes uplink transmission performed on at least one second cell respectively; the first downlink transmission includes downlink transmission performed on at least one second cell respectively.

[0128] It should be noted that the first cell used to send the first information can be referred to as a scheduling cell; the second cell where the first uplink transmission and / or the first downlink transmission scheduled by the first information is located can be referred to as a scheduled cell; wherein, the scheduled cell can also include the first cell. In the case where the scheduled cell includes the first cell, the first uplink transmission scheduled by the first information can include uplink transmission on the first cell, and the first downlink transmission scheduled by the first information can include downlink transmission on the first cell.

[0132] In some embodiments, the PDCCH can carry multi-downlink control information (MDCI) for scheduling a PUSCH on at least one second cell and / or scheduling a PDSCH on at least one second cell.

[0133] In some embodiments, the terminal receives first information from the first cell; wherein the first information is used to schedule a first uplink transmission, the first uplink transmission includes an uplink transmission on at least one second cell; the time domain offset value K offse,i of the first cell and the time domain offset value K offse,j of each second cell can be determined; and the time domain position of the first uplink resource used for the first uplink transmission is determined based on the time domain offset value K offse,i of the first cell and the time domain offset value K offse,j of each second cell; wherein the first uplink resource includes an uplink resource used for uplink transmission on each second cell.

[0134] In some embodiments, the terminal receives first information from the first cell; wherein the first information is used to schedule a first downlink transmission, the first downlink transmission includes a downlink transmission on at least one second cell; the time domain offset value K offse,ia time domain offset value K of each second cell offse,j and a time domain offset value K of each second cell offse,i a time domain offset value K of each second cell offse,j determining a time domain position of a first downlink resource for the first downlink transmission; wherein the first downlink resource comprises a downlink resource for downlink transmission on each second cell.

[0135] For example, the network device sends a PDCCH from cell#1 to the terminal through a satellite network, the MDCI carried by the PDCCH is used to schedule a PDSCH using multi-carrier scheduling, including a PDSCH on cell#2 and a PDSCH on cell#3. The terminal can determine a time domain offset value K of cell#1 offse,1 , a time domain offset value K of cell#2 offse,2 , and a time domain offset value K of cell#3 offse,3 ; then, based on the time domain offset value K of cell#1 offse,1 and the time domain offset value K of cell#2 offse,2 , the PDSCH resource on cell#2 is calculated, based on the time domain offset value K of cell#1 offse,1 and the time domain offset value K of cell#3 offse,3 , the PDSCH resource on cell#3 is calculated.

[0136] It should be noted that the first information indicating the scheduled first uplink transmission can also include uplink transmission on the first cell. The first information indicating the scheduled first downlink transmission can also include downlink transmission on the first cell. Accordingly, when determining the uplink resource on the first cell for the first uplink transmission and / or the downlink resource on the first cell for the first downlink transmission, the time domain offset value of the first cell can not be used.

[0137] It should be noted that the time domain unit indicated by the time domain offset value can be set according to actual needs, which can be frame, subframe, slot, symbol, millisecond (ms), etc. For the sake of simplicity, in the following embodiments, slots are used as examples.

[0160] In some embodiments, in a case that the first information is used for scheduling the first downlink transmission, after the terminal receives the first downlink transmission from the network device on the first downlink resource, the terminal can send a second uplink transmission to the network device based on a feedback mechanism for the first downlink transmission, the second uplink transmission being used for sending feedback information for the first downlink transmission. Wherein, the time domain position of the second uplink resource used for the second uplink transmission can be determined based on the first downlink resource.

[0161] In some embodiments, after the terminal determines the first downlink resource used for the first downlink transmission, the terminal can determine a latest downlink resource from the first downlink resource; based on the time domain position of the latest downlink resource, determine the time domain position of the second uplink resource.

[0162] In some embodiments, the first downlink transmission scheduled by the first information can include downlink transmissions on multiple first cells, the first downlink resource used for the first downlink transmission includes downlink resources on the multiple first cells, the terminal can determine a latest downlink resource, for example, a latest slot, from the downlink resources of the multiple second cells, and determine the second uplink resource for the second uplink transmission with the latest downlink resource as a reference time domain resource, for example, a reference slot; wherein, the second uplink resource is later than the latest downlink resource.

[0163] Wherein, the cell used for the second uplink transmission can be the first cell used for receiving the first information.

[0164] In some embodiments, the feedback information for the first downlink transmission can be a hybrid automatic repeat request (HARQ), and the corresponding second uplink transmission can be a PUCCH.

[0165] In some embodiments, the terminal receives a PDCCH from a first cell cell#i, wherein the DCI in the PDCCH is used for scheduling a PDSCH on at least one second cell cell#j; the terminal can determine a time domain offset value K offse,i and a time domain offset value K offse,j, to obtain the PDSCH resource on each second cell cell#j; determine the latest PDSCH resource from the PDSCH resource of each second cell cell#j as the latest downlink resource; determine the PUCCH resource on the first cell cell#i based on the latest PDSCH resource; the terminal receives the PDSCH on the PDSCH resource of each second cell cell#j; and then sends the PUCCH to the network device on the PUCCH resource of the first cell, wherein the PUCCH carries the HARQ information of the terminal to the PDSCH on each second cell cell#j.

[0166] For example, the terminal receives the PDCCH on cell#1 from the network device, and the DCI in the PDCCH is used to schedule the PDSCH on cell#2, cell#3 and cell#4. The terminal can obtain the PDSCH resource on cell#2, cell#3 and cell#4 as Slot#2, Slot#3 and Slot#4 respectively based on the time domain offset value K offse,1 of cell#1, offse,2 the time domain offset value K offse,3 of cell#3, offse,4 and the time domain offset value K offse,lastest of cell#4. offset,i Then, the terminal can determine the PUCCH resource on cell#1 as Slot#5 based on Slot#3.

[0167] In some embodiments, the time domain position of the second uplink resource is determined based on the time domain position of the latest downlink resource, the time domain interval between the first downlink resource and the second uplink resource indicated in the first information, the time domain offset value of the second cell where the latest downlink resource is located, the difference between the first time domain offset value and the second time domain offset value.

[0168] In some embodiments, the time domain position of the second uplink resource can be calculated by the following formula:

[0169] Wherein, n1 is used to indicate the time domain position of the latest downlink resource, is used to indicate the subcarrier spacing of the cell where the latest downlink resource is located, K1 is used to indicate the time domain interval between the first downlink resource and the second uplink resource indicated in the first information; K offse,lastest is used to indicate the time domain offset value of the second cell where the latest downlink resource is located; K offset,i is used to indicate the time domain offset value of the first cell.

[0170] In some embodiments, the calculation formula of the time domain position of the second uplink resource can also be represented as follows:

[0171] wherein, K is used to indicate the subcarrier spacing of the latest downlink resource in the cell to which the subcarrier spacing is switched. offset,PUCCH K is used to indicate the time domain offset value of the cell in which the PUCCH is located.

[0172] In some embodiments, the calculation formula of the time domain position of the second uplink resource can also be expressed as follows: n1+K offset,latest +K1

[0173] wherein, K offset,latest K is used to indicate the time domain offset value of the second cell in which the latest downlink resource is located.

[0174] In some embodiments, since the terminal does not need to feed back all the downlink transmissions contained in the received first downlink transmission, the terminal can not consider the downlink transmission that does not need to be fed back in the determination of the latest downlink resource. The second cell in which the downlink transmission that does not need to be fed back is located can be configured as disabled for the HARQ process.

[0175] In some embodiments, in the case that the first downlink transmission scheduled by the first information includes downlink transmissions on multiple second cells, the second cell that needs to be fed back can be determined from the scheduled multiple second cells first; and then the latest downlink resource is determined from the downlink resources of the second cell that needs to be fed back.

[0176] In some embodiments, in the case that the first downlink transmission scheduled by the first information includes downlink transmissions on multiple second cells, the downlink transmission that needs to be fed back can be determined from the scheduled first downlink transmission first; and then the latest downlink resource is determined from the downlink transmission that needs to be fed back.

[0177] For example, the terminal receives a PDCCH on cell#1 from the network device, and the PDCCH is used to schedule PDSCHs on cell#2, cell#3 and cell#4. The terminal can determine the latest downlink resource based on the time domain offset value K offse,1 of cell#1, the time domain offset value K offse,2 of cell#2, the time domain offset value K offse,3 of cell#3, and the time domain offset value K offse,4, the PDSCH resources of cell#2, cell#3 and cell#4 are Slot#2, Slot#3 and Slot#4 respectively, and the order of the three PDSCH resources is Slot#4, Slot#2 and Slot#3; but since cell#3 is configured as disable for the HARQ process, Slot#2 is the latest downlink resource; then, the terminal can determine the PUCCH resource on cell#1 as Slot#5 with Slot#2 as the reference time slot. In this case, Slot#5 is required to be later than Slot#2, and can not be later than Slot#3.

[0178] In some embodiments, when configuring the time domain bias value for each cell, the time domain bias value configured for each cell is respectively configured; or the corresponding time domain bias value for each cell set in which each cell is located can also be configured, that is, the time domain bias value is configured per cell set, so that each cell in the same cell set can share the same time domain bias value.

[0179] The cell set can be a cell set for multi-carrier scheduling. For example, K offset #0 is configured for cell set#0, K offset #1 is configured for cell set#1, and K offset #2 is configured for cell set#2.

[0180] In some embodiments, the determined time domain bias value can further include a third time domain bias value of a first cell set in which the first cell is located, the third time domain bias value being used to compensate for partial time delay of each cell in the first cell set; and / or a fourth time domain bias value of a second cell set in which the second cell is located, the fourth time domain bias value being used to compensate for partial time delay of each cell in the second cell set.

[0181] By configuring the corresponding time domain bias value for each cell set, the number of information sent by the network device to the terminal for updating the time domain bias value of the cell can be reduced, for example, frequent sending of MAC CE for updating each cell due to errors of the network device and the terminal can be avoided.

[0182] In some embodiments, the cells that can be divided into the same cell set are required to meet the distance therebetween within a certain range, or the difference between the time domain bias values of the cells in the same cell set is required to be less than or equal to a time domain threshold, that is, the terminal does not expect the difference between the time domain bias values respectively configured for each cell in the same cell set to be greater than or equal to the time domain threshold.

[0183] In some embodiments, a first time domain bias value can be configured for a cell only; or a second time domain bias value can be configured for a cell group only and used as the time domain bias value for all cells in the cell group; or a first time domain bias value can be configured for each cell respectively and a second time domain bias value can be configured for a cell group.

[0184] In some embodiments, when a time domain bias value is configured for a cell group, the time domain bias value of the cell group can be configured or updated only after the configuration information carrying the time domain bias value is received on one cell in the cell group.

[0185] For example, a terminal can receive a second time domain bias value configured or updated for a cell group in which a third cell is located from the third cell, and the second time domain bias value of the cell group in which the third cell is located can be updated through a MAC CE received on the third cell.

[0186] In an implementation, a cell for receiving a time domain bias value of a cell group can be a first cell for a terminal to receive first information, i.e., a scheduling cell for detecting a corresponding DCI; or can be a specific reference cell for the terminal to receive specific configuration information, which can include a timing-related index, i.e., the terminal obtains the timing-related index on the reference cell.
