METHOD AND APPARATUS FOR TRANSMITTING UPLINK DATA |
| 摘要 |
A wireless terminal selects a first random access preamble in a random access preamble group for a small-sized data transmission (SDT) and transmits the selected first random access preamble to a base station, if a size of a data packet to be transmitted is smaller than a maximum SDT size set for the SDT and receives a random access response message including a first uplink resource from the base station. Further, the wireless terminal transmits the data packet using the first uplink resource without an RRC connection setup with the base station. |

1. A method for transmitting, by a wireless terminal, uplink data, comprising:
selecting a first random access preamble in a random access preamble group for a small-sized data transmission (SDT) and transmitting the selected first random access preamble to a base station, if a size of a data packet to be transmitted is smaller than a maximum SDT size set for the SDT; receiving a random access response message including a first uplink resource from the base station; and transmitting the data packet using the first uplink resource without a radio resource control (RRC) connection setup with the base station. |
