In an implementation manner of the present application, the data transmission quality is determined by the terminal device based on a signal strength of the terminal device, where the signal strength is an average signal strength of the terminal device in a first time period, and an end time of the first time period is a time when the terminal device sends the first information.

Firstly, because the serving cells in which # C1, # C2 and # C5 are located are the same serving cell and the serving cells in which # C3 and # C4 are located are the same serving cell, the group in which # C1, # C2 and # C5 are located is the same group, i.e. the group in which # C3 and # C4 are located is another group, i.e. G2; then, since the signal strength of # C1 is 3 and the signal strength of # C5 is 4, the packet in which # C1 and # C4 are located is G3, the target signal strength range corresponding to G3 is [3,4], # C2 is G4, the target signal strength range corresponding to G1, 2], and G1 includes G3 and G4, and since the signal strength of # C3 is 2 and the signal strength of # C4 is 3, the packet in which # C3 and G4 are located is G5 and the target signal strength range corresponding to G5 is [2,3], and finally, the terminal devices in G3, G4, and G5 are randomly assigned to other packets.

In a possible implementation manner, the determining, by the terminal device, the second preset data amount and the third preset data amount based on the first data amount, the second time period, and the transmission time length each includes:
the terminal equipment determines the second preset data volume based on the first data volume, the duration of the second time period, the transmission time length and a fourth formula;
and the terminal equipment determines the third preset data volume based on the first data volume, the duration of the second time period, the transmission time length and a fifth formula.

For example, the transmission time length in the transmission time configuration information is 20s, the time length of the second period is 15s, the target data packet to be transmitted is 16M, and α is equal to 1, so that the first preset data amount is 1 × 15 × 16/20=12m.
The fifth formula is D1= β C1 × D2/C2, where D1 is a preset data amount, D2 is a data amount of a data packet to be transmitted, C1 and C2 are both transmission time lengths, C1 is smaller than C2, and β is a parameter and can be set according to a situation.
Wherein A1 is greater than C1.
For example, the transmission time configuration information has a transmission time length of 20s, the time length of the second time period is 5s, the target data packet to be transmitted is 16M, α is equal to 0.8, and the second predetermined data amount is 0.8 × 5 × 16/20=3.2m.
It can be seen that, in the embodiment of the present application, the retransmission times are determined according to the size relationship between the second data amount and the second preset data amount and the size relationship between the second data amount and the third preset data amount, which is beneficial to improving the effectiveness of data transmission.
