Data transmission method and user equipment

User equipment, comprising:

• a processor;
• and
• a memory coupled to the processor, and having processor-executable instructions stored thereon, which when executed cause the processor to implement operations including:
• obtaining time resource grouping information, wherein the time resource grouping information comprises physical resource numbers of physical resources in N time resource groups, and N is a positive integer;
• wherein N×k subframes as time resources are grouped into N groups, each time resource group includes k time resources, each time resource includes t frequency resources, and there are a total of k×t physical resources, where k and t are positive integers, in each time resource group, time resource numbers of the physical resources are 0, 1, . . . , k−1, frequency resource numbers of the physical resources are 0, 1, . . . , t−1, and physical resource numbers of the physical resources are 0, 1, . . . , k×t−1;
• sending an indication signal, wherein the indication signal indicates one or more physical resource numbers;
• determining, according to the time resource grouping information and the one or more physical resource numbers indicated by the indication signal, time resources occupied by a data signal in the N time resource groups;
• and
• sending the data signal by using the time resources occupied by the data signal in the N time resource groups.
