USER EQUIPMENT AND COMMUNICATION CONTROL METHOD |
| 摘要 |
Techniques are disclosed for implementing the LBT in consideration of propagation delay differences in a cell. One aspect of the present invention relates to user equipment, comprising: a transmission and reception unit configured to use a scheduled radio resource to perform transmission and reception to/from a base station via a cell; and a frequency usage detection unit configured to perform Listen Before Talk (LBT) on a frequency band in the cell at an LBT timing independent of a scheduled uplink transmission timing, wherein when the frequency usage detection unit determines that no other user equipment is communicating in the frequency band, the transmission and reception unit performs uplink transmission to the base station. |
