Terminal, network device, and data transmission method in random access process

A base station, comprising:

• a receiver, configured to receive first indication information from a terminal, wherein the first indication information indicates to the base station that data of multiple transmission time intervals (TTIs) is to be transmitted from the terminal to the base station in one random access process;
• and
• a processor, configured to determine, according to the first indication information, that data of multiple transmission time intervals (TTIs) is to be transmitted from the terminal to the base station in a current random access process;
• wherein the first indication information further indicates:
• the number of TTIs in which data is to be transmitted from the terminal to the base station;
• or
• the terminal needs to transmit data of another TTI in the current random access process after transmitting data of a current TTI;
• or
• data of a current TTI is the last data to be transmitted by the terminal in the current random access process.

A radio network controller (RNC), comprising:

• a processor, configured to determine to allow a terminal to transmit data of multiple transmission time intervals (TTIs) to a base station in one random access process;
• and
• a transmitter, configured to send third indication information to the terminal, wherein the third indication information indicates that the terminal is allowed to transmit data of multiple TTIs to the base station in a current random access process;
• wherein the third indication information comprises:
• a maximum quantity of TTIs in which the terminal is allowed to transmit data to the base station in one random access process;
• indication information indicating that the terminal is allowed to transmit data of multiple TTIs to the base station in one random access process;
• a data volume threshold;
• a correspondence between information about a physical resource to be used by the terminal to send an access preamble and a quantity of TTIs in which data is to be transmitted by the terminal to the base station in one random access process;
• and/or
• information about a physical resource that is available when the terminal needs to send data of multiple TTIs to the base station in one random access process.

A data transmission method in a random access process, comprising:

• and
• sending, by the terminal, first indication information to the base station, wherein the first indication information indicates that data of multiple TTIs is to be transmitted from the terminal to the base station in the current random access process;
• wherein the first indication information further indicates:
• the number of TTIs in which data is to be transmitted from the terminal to the base station;
• or
• the terminal needs to transmit data of another TTI in the current random access process after transmitting data of a current TTI;
• or
• data of a current TTI is the last data to be transmitted by the terminal in the current random access process.
