Abstract
Provided is a terminal apparatus including: a measurement unit that can measure a time difference between reception and transmission by the terminal apparatus; a transmitter that can report a measurement result of the time difference based on an event associated with the measurement of the time difference, wherein in a case that the prescribed Transmission Time Interval (TTI) length is configured, and in addition, in a case that the measurement result is greater than a prescribed threshold, the transmitter reports the measurement result to the terminal apparatus. The transmission efficiency is thus improved.
Claims12
A terminal apparatus that communicates with a base station apparatus comprising:
- a receiver configured to receive a timing advance command with a timing advance value;
- and to receive higher layer signaling with a first parameter indicating a length of short TTI and a second parameter indicating to shorten a processing time for transmission timing;
- and
- a transmitter configured to transmit an uplink signal, wherein the transmitter is configured to advance uplink transmission timing for the uplink signal based on the timing advance value, the first parameter and the second parameter.
A method of a terminal apparatus that communicates with a base station apparatus, the method comprising:
- receiving a timing advance command with a timing advance value
- receiving higher layer signaling with a first parameter indicating a length of short TTI and a second parameter indicating to shorten a processing time for transmission timing;
- and
- transmitting an uplink signal, wherein uplink transmission timing for the uplink signal is advanced based on the timing advance value, the first parameter and the second parameter.
