[0129] Please refer to Figure 2 , Figure 2 is a flowchart of an indication method provided by the embodiments of the present disclosure, which is executed by a terminal device. As Figure 2 shown, the method can include but is not limited to the following steps:
[0130] Step 201, receiving a scheduling instruction.
[0131] Generally, the terminal device can obtain the scheduling instruction and the like by receiving the DCI carried on the physical downlink control channel (PDCCH), and the present disclosure does not limit this.
[0132] Optionally, the scheduling instruction can be downlink control information (DCI), so that the terminal device can determine that the scheduling instruction is received and the like under the condition that the DCI is received, and the present disclosure does not limit this.
[0133] Step 202, obtaining transmission configuration information from the scheduling instruction.
[0134] Step 203, determining the transmission parameter of each cell in the plurality of scheduled cells according to the transmission configuration information.
[0135] The transmission configuration information can include the transmission information corresponding to each scheduled cell, or can include the transmission information corresponding to the reference cell in the plurality of scheduled cells, and the present disclosure does not limit this.
[0136] Optionally, the transmission parameter can include at least one of the following: a modulation and coding scheme (MCS), a time domain resource allocation (TDRA), and a frequency domain resource allocation (FDRA).
[0137] For example, the transmission parameter can be the MCS, or the TDRA, or the FDRA, or the MCS and the TDRA, or the MCS and the FDRA, or the TDRA and the FDRA, or the MCS, the TDRA, and the FDRA, and the like, which are not limited in the present disclosure.
[0138] In the embodiments of the present disclosure, the terminal device can first receive the scheduling instruction, then obtain the transmission configuration information from the scheduling instruction, and determine the transmission parameter of each cell in the scheduled multiple cells according to the transmission configuration information. Thus, by analyzing the received scheduling instruction, the transmission configuration information can be determined, and then based on the transmission configuration information, the transmission parameter of each cell in the scheduled multiple cells can be determined, that is, the transmission mechanism of multiple different cells jointly scheduled in one scheduling instruction can be realized, so that in the case of supporting multi-cell scheduling, the signaling overhead of the indication information can be effectively reduced.
[0139] Please refer to Figure 3 , Figure 3 is a flowchart of an indication method provided by the embodiments of the present disclosure, which is executed by a terminal device. As shown in Figure 3 , the method can include but is not limited to the following steps:
[0140] Step 301, receiving a scheduling instruction.
[0141] Optionally, the scheduling instruction can be a DCI.
[0142] Step 302, obtaining multiple first indication information from the scheduling instruction.
[0143] Step 303, determining the transmission parameter of each cell in the scheduled multiple cells according to the multiple first indication information.
[0144] Optionally, the transmission configuration information can include multiple first indication information, and the multiple first indication information can be used to indicate the transmission parameter of the scheduled multiple cells. For example, the first indication information 1 can be used to indicate the transmission parameter of cell 1 in the scheduled multiple cells, the first indication information 2 can be used to indicate the transmission parameter of cell 2 in the scheduled multiple cells, and the like, which are not limited in the present disclosure.
[0145] Therefore, in the embodiments of the present disclosure, after receiving the scheduling instruction, the terminal device can determine the plurality of first indication information contained in the scheduling instruction by analyzing the scheduling instruction, and then determine the transmission parameter of each cell in the plurality of scheduled cells according to the indication of each first indication information, and the present disclosure does not limit this.
[0146] Optionally, the transmission parameter can include at least one of MCS, TDRA and FDRA.
[0147] For example, in the case that the plurality of scheduled cells are cell 1, cell 2, cell 3 and cell 4, if the analysis of the plurality of first indication information obtained from the scheduling instruction obtains MCS1, MCS2, MCS3 and MCS4, it can be determined that the transmission parameter of cell 1 in the plurality of scheduled cells is MCS1, the transmission parameter of cell 2 is MCS2, the transmission parameter of cell 3 is MCS3, and the transmission parameter of cell 4 is MCS4.
[0148] Or, in the case that the plurality of scheduled cells are cell 1, cell 2 and cell 3, if the analysis of the plurality of first indication information obtained from the scheduling instruction obtains FDRA1, FDRA2 and FDRA3, it can be determined that the transmission parameter of cell 1 in the plurality of scheduled cells is FDRA1, the transmission parameter of cell 2 is FDRA2, and the transmission parameter of cell 3 is FDRA3.
[0149] Or, in the case that the plurality of scheduled cells are cell 1, cell 2 and cell 3, if the analysis of the plurality of first indication information obtained from the scheduling instruction obtains TDRA1, TDRA2 and TDRA3, it can be determined that the transmission parameter of cell 1 in the plurality of scheduled cells is TDRA1, the transmission parameter of cell 2 is TDRA2, and the transmission parameter of cell 3 is TDRA3.
[0150] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the scheduled cells and transmission parameters in the embodiments of the present disclosure.
[0151] Optionally, different information fields in the scheduling instruction can carry the transmission configuration of different cells, such as information field 1 can be used to carry the transmission configuration of cell 1, information field 2 can be used to carry the transmission configuration of cell 2, and the present disclosure does not limit this.
[0152] In the embodiment of the present disclosure, the terminal device can first receive a scheduling instruction, then obtain a plurality of first indication information from the scheduling instruction, and determine the transmission parameter of each cell in the plurality of scheduled cells according to the plurality of first indication information. Thus, by analyzing the received scheduling instruction, the plurality of first indication information contained can be determined, and then based on each first indication information, the transmission parameter of each cell in the plurality of scheduled cells can be determined, so that in the case of supporting multi-cell scheduling, the signaling overhead of indication information can be effectively reduced.
[0153] Please refer to Figure 4 , Figure 4 is a flowchart of an indication method provided by the embodiment of the present disclosure, which is executed by a terminal device. As shown in Figure 4 , the method can include but is not limited to the following steps:
[0154] Step 401, receiving a scheduling instruction.
[0155] Optionally, the scheduling instruction can be DCI.
[0156] Step 402, determining a reference cell in a plurality of cells.
[0157] It can be understood that for the plurality of scheduled cells, a reference cell in the plurality of cells can be first determined. For example, the received scheduling instruction can be analyzed to determine the reference cell in the plurality of scheduled cells. Alternatively, the reference cell in the plurality of cells can be determined based on protocol agreement, network device configuration, etc., which is not limited in the present disclosure.
[0158] Step 403, obtaining the transmission parameter of the reference cell as a reference transmission parameter.
[0159] Optionally, the transmission parameter can be at least one of MCS, FDRA and TDRA.
[0160] Among them, the received scheduling instruction can be analyzed to determine the transmission parameter of the reference cell in the plurality of cells, and then the transmission parameter of the reference cell can be used as the reference transmission parameter corresponding to the plurality of scheduled cells. For example, the reference cell is cell 1 in the plurality of scheduled cells, and the corresponding transmission parameter is TDRA1, then "TDRA1" can be used as the reference transmission parameter, etc., which is not limited in the present disclosure.
[0161] Step 404, obtaining second indication information from the transmission configuration information, the second indication information being used to indicate the offset value of other cells in the plurality of cells.
[0162] It can be understood that the terminal device can obtain the transmission configuration information by analyzing the scheduling instruction, and then based on the indication of the second indication information in the transmission configuration information, the offset value of the other cells in the plurality of cells relative to the reference cell can be obtained, that is, the offset value of the transmission parameter of the other cells relative to the reference transmission parameter, and the like, which is not limited in the present disclosure.
[0163] In addition, in the case of the transmission parameter being the FDRA, the offset value can be the offset value between the starting positions of the frequency domain allocation, and the like, which is not limited in the present disclosure.
[0164] For example, if the other cells in the plurality of scheduled cells are cell 2, cell 3 and cell 4, respectively, and the terminal device obtains the second indication information indicating offset value 1, offset value 2 and offset value 3 by analyzing the scheduling instruction, it can be determined that the offset value of cell 2 is offset value 1, the offset value of cell 3 is offset value 2, the offset value of cell 4 is offset value 3, and the like, which is not limited in the present disclosure.
[0165] Step 405, determining the transmission parameter of the other cells according to the reference transmission parameter and the second indication information.
[0166] Among them, the sum of the offset value of any other cell indicated by the second indication information and the reference transmission parameter can be used as the transmission parameter of the any other cell, which is not limited in the present disclosure.
[0167] For example, if the reference transmission parameter is MCS1, and the offset value of the other cell 1 in the plurality of cells to be scheduled indicated by the second indication information is offset value 2, then the transmission parameter of the other cell 1 can be determined as MCS1+offset value 2. Or, if the reference transmission parameter is FDRA2, and the offset value of the other cell 2 in the plurality of cells to be scheduled indicated by the second indication information is offset value 3, then the transmission parameter of the other cell 2 can be determined as FDRA2+offset value 3. The present disclosure is not limited to this.
[0168] Optionally, in the case of carrying the transmission configuration of different cells on different information domains, the terminal device can determine the correspondence between the offset value and the information domain value through the high layer signaling or the physical layer signaling of the network device. Then the transmission parameter of the other cell can be determined through the correspondence, the information domain value in the scheduling instruction and the reference transmission parameter of the reference cell.
[0169] For example, the correspondence between the information domain value in the scheduling instruction and the offset value can be as shown in Table 1:
[0170] Table 1
[0171] Information field value Offset value 00 Offset value 1 01 Offset value 2 10 Offset value 3 11 Offset value 4

The value of each element and each corresponding relationship is independent of any other element value or corresponding relationship in the table 1. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in the table 1 is an independent embodiment.

Thus, by analyzing the received scheduling instruction, the reference cell and the reference transmission parameter can be obtained, and then based on the offset value indicated by the second indication information, the transmission parameter of the other cell in the plurality of cells to be scheduled can be determined, so that in the case of supporting multi-cell scheduling, the signaling overhead of the indication information can be effectively reduced.
