USER TERMINAL, RADIO BASE STATION AND RADIO COMMUNICATION METHOD

摘要

The present invention is designed to improve throughput and support various modes of use of radio communication systems when TDD is used in an environment in which the data traffic is unevenly concentrated on the downlink. A user terminal carries out radio communication with a TDD cell, and has a transmitting/receiving section that transmits and receives signals by using a UL/DL configuration, which includes a special subframe formed with a downlink time duration, a guard period and an uplink time duration, and in which DL communication is carried out in all subframes, and a control section that configures the uplink time duration to constitute the special subframe to at least three symbols or more, and controls the allocation of uplink signals.

1. A user terminal that carries out radio communication with a TDD cell, comprising:
a transmitting/receiving section that transmits and receives signals by using a UL/DL configuration, which includes a special subframe formed with a downlink time duration, a guard period and an uplink time duration, and in which DL communication is carried out in all subframes; and a control section that configures the uplink time duration to constitute the special subframe to at least three symbols or more, and controls allocation of uplink signals.
