AI Technical Summary
In LTE communication systems, especially in unlicensed bands, uplink transmission efficiency is hindered due to interference from other communication systems, and existing methods like LBT do not effectively manage channel availability for efficient data transmission.
A terminal apparatus and base station apparatus are designed to perform Listen-Before-Talk (LBT) procedures, where a channel measurement unit in the terminal apparatus and a radio resource control unit in the base station apparatus allocate and manage subframes for uplink transmission based on random access response grants, ensuring efficient PUSCH transmission even when the channel is busy.
This solution enables efficient uplink transmission by optimizing subframe allocation and LBT procedures, improving data transmission reliability and efficiency in unlicensed bands by minimizing interference.
