Abstract
In order that a user terminal properly performs communication even when a plurality of TTIs with different time lengths is present, a user terminal of the present invention transmits an uplink shared channel in a normal TTI and/or a shortened TTI including the smaller number of symbols than the normal TTI. The user terminal controls transmission power of the uplink shared channel based on an individual parameter individually set according to a TTI length for transmitting the uplink shared channel.
Claims9
A terminal comprising:
- a receiver that receives downlink control information (DCI) for scheduling an uplink shared channel in a given period with one of a plurality of different lengths;
- and
- a processor that controls transmission power of the uplink shared channel based on an accumulation value of transmission power control (TPC) commands in the DCI that are accumulated irrespective of the length of the given period.
A radio communication method, for a terminal, comprising:
- receiving downlink control information (DCI) for scheduling an uplink shared channel in a given period with one of a plurality of different lengths;
- and
- controlling transmission power of the uplink shared channel based on an accumulation value of transmission power control (TPC) commands in the DCI that are accumulated irrespective of the length of the given period.
