Abstract

Embodiments provide user equipment includes a processor and a transmitter. The processor determines a time domain resource within a T2 time length based on second time domain resource indication information, where the second time domain resource indication information indicates a time domain resource occupied for data transmission within a T1 time length, and T2 is twice of T1. The processor further generates second control information, where the second control information includes the second time domain resource indication information. The transmitter sends the second control information. The transmitter further sends data on the time domain resource that is determined within the T2 time length. In this way, only a time domain pattern with a half time length of a period is defined, so that total time domain patterns in a system are applicable to a vehicle-to-vehicle communication scenario. In addition, time domain resource indication information occupies fewer bits, thereby saving system resources.
