Terminal apparatus and communication system
In order to perform efficient communications. A terminal apparatus includes a higher layer processing unit configured to configure a subcarrier spacing of a physical channel, based on a first parameter, and a transmission unit configured to perform an uplink transmission by using the physical channel. In a case that transmissions on a first physical channel configured with a first subcarrier spacing and a second physical channel configured with a second subcarrier spacing occur in one serving cell, and that the second subcarrier spacing is wider than the first subcarrier spacing, the transmission unit allocates a transmit power on a priority basis to the second physical channel.
1. A terminal apparatus comprising:
receiving circuitry that receives a Downlink Control Information (DCI) format; and
transmitting circuitry that transmits a Physical Uplink Shared CHannel (PUSCH) based on the DCI format, wherein
in a case that a first PUSCH configuration and a second PUSCH configuration are configured:
the first PUSCH configuration is associated with a first subcarrier spacing;
the second PUSCH configuration is associated with a second subcarrier spacing;
and
transmissions of a first PUSCH and a second PUSCH are overlapped in a same timing; and
the transmitting circuitry sets transmission power of the first PUSCH and the second PUSCH based on a priority order of control information included in each of the first PUSCH and the second PUSCH.
2. The terminal apparatus according to claim 1 , wherein
a subcarrier spacing is configured based on an operating band supported by the terminal apparatus.
3. A method for a terminal apparatus, the method comprising:
receiving a Downlink Control Information (DCI) format; and
transmitting Physical Uplink Shared CHannel (PUSCH) based on the DCI format, wherein
in a case that a first PUSCH configuration and a second PUSCH configuration are configured:
the first PUSCH configuration is associated with a first subcarrier spacing;
the second PUSCH configuration is associated with a second subcarrier spacing; and
transmissions of a first PUSCH and a second PUSCH are overlapped in a same timing; and
setting transmission power of the first PUSCH and the second PUSCH based on a priority order of control information included in each of the first PUSCH and the second PUSCH.
4. The method for a terminal apparatus according to claim 3 , wherein
a subcarrier spacing is configured based on an operating band supported by the terminal apparatus.
