Abstract: The present disclosure provides a data sending method. A first terminal device, determines at least two carriers to transmit at least two pieces of data corresponding to a same transport block, and in a one-to-one correspondence with the at least two pieces of data. The at least two pieces of data can be sent by the first terminal to a second terminal device or a network device by using the at least two carriers. When the first terminal device sends data, the first terminal device may send the at least two pieces of data to the second terminal device or the network device on the at least two carriers to improve reliability of data transmission. The at least two pieces of data may be sent simultaneously, to avoid an increased latency by transmissions of the at least two pieces of data in different time units.

Abstract: Example scheduling assignment information transmission methods, systems, and devices are described. One example method includes obtaining, by a user equipment (UE), a multiplexing manner used to indicate a relationship between a time-frequency resource for transmitting scheduling assignment information and a time-frequency resource for transmitting data information. The UE receives downlink control information comprising scheduling assignment resource indication information sent by a network device, and obtains, based on the scheduling assignment resource indication information and the multiplexing manner, resource location information occupied to transmit the scheduling assignment information. The UE can then transmit the scheduling assignment information based on the resource location information occupied by the scheduling assignment information.

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.
