In some embodiments, the first indication message is downlink control information DCI. The terminal device needs to receive the DCI before receiving the downlink data (PDSCH reception) sent by the network device, determine the receiving position of the PDSCH according to the indication in the DCI, and determine the resource position of the HARQ-ACK feedback according to the HARQ-ACK related indication information in the DCI. Therefore, the embodiment of the present application can solve the problem of different uplink and downlink transmission resources in the process of data scheduling and save resource overhead by directly indicating the transmission resource index for data transmission of the terminal device in the DCI.

Optionally, the first indication message includes a first bit field and a second bit field, the first bit field is used to indicate an uplink or downlink transmission resource index, and the second bit field is used to indicate transmission resource indication information.

In the embodiment of the present application, two bit fields are introduced into the downlink scheduling DCI message, namely the first bit field and the second bit field. The first bit field is used to indicate the uplink or downlink transmission resource index, and the second bit field is used to indicate the first Whether the bit field indicates a downlink transmission resource index or an uplink transmission resource index.

If the value of the first bit field is 0100, it indicates that RE_down3 is a downlink available resource. If the value of the first bit field is 1000, it indicates that RE_down4 is an available downlink resource; if the value of the first bit field is 0001, it indicates that RE_down1 is an available downlink resource. When the value of the second bit field is 0, it means that when the first bit field indicates the uplink transmission resource index, the first bit field is 3 bits, and each bit corresponds to a candidate uplink transmission resource. If the value of the first bit field is 100, then Indicates that RE_up3 is an available uplink resource; if the value of the first bit field is 010, it indicates that RE_up2 is an available uplink resource; if the value of the first bit field is 001, it indicates that RE_up1 is an available uplink resource.

For example, in order to save bit overhead, the first bit field can be represented by K bit codewords, that is, the number of bits in the first bit field is K, and K is a positive integer,

Indicates upward rounding. When M is 3 or 4, K takes 2. When M is 5 to 8, K takes 3. When M is 9 to 16, K takes 4.

The resource index can solve the problem that the uplink and downlink transmission resources of the terminal equipment are different during the data scheduling process, and save bit overhead.

Please refer to FIG. 5 . FIG. 5 is a schematic flowchart of another transmission resource indication method provided by an embodiment of the present application, which is applied to the wireless communication system shown in FIG. 1 . As shown in Figure 5, the method includes the following steps.

S510. The network device sends a first indication message to the terminal device. The first indication message is used to indicate a transmission resource index for data transmission. The data transmission is data transmission between the terminal device and the satellite. The first indication message includes an uplink transmission resource index and Downlink transmission resource index.

In some embodiments, a cell is composed of multiple beams, and different beams may correspond to different carriers, part of the bandwidth ((Bandwidth Part), BWP) or narrowband, and the network device indicates the carrier, BWP or narrowband of the data transmission of the terminal device index, so that when the terminal equipment needs to switch beams frequently, the beam switching is realized by switching the carrier, BWP or narrowband.

In this embodiment of the application, the network device determines the terminal device to receive the DCI and PDSCH and send the HARQ-ACK transmission resource index through the location of the terminal device, the beam distribution in the cell, and the ephemeris information, and configures the terminal device and the satellite for the terminal device The uplink and downlink transmission resource indexes of the data transmission between them, so as to solve the problem of different uplink and downlink transmission resources in the data scheduling process.

Optionally, the first indication message includes a third bit field and a fourth bit field, the third bit field is used to indicate the downlink transmission resource index, and the fourth bit field is used to indicate the uplink transmission resource index.
