Terminal and uplink transmission method
A terminal including: a control unit configured to compare a power reduction total value that is reduced from a maximum transmission power value determined based on a power class and that does not include a power reduction value for adjusting the power class with a predetermined value, and to calculate a lower limit value of a maximum transmission power by setting the power reduction value for adjusting the power class as 0 dB when the power reduction total value is greater than the predetermined value; and a transmission unit configured to perform uplink transmission using a maximum transmission power value equal to or greater than the lower limit value.
1. A terminal comprising:
a control unit configured
to compare a power reduction total value that is reduced from a maximum transmission power value determined based on a power class and that does not include a power reduction value for adjusting the power class with a predetermined value, and
to calculate a lower limit value of a maximum transmission power by setting the power reduction value for adjusting the power class as 0 dB when the power reduction total value is greater than the predetermined value; and
a transmission unit configured to perform uplink transmission using a maximum transmission power value equal to or greater than the lower limit value.
2. The terminal as claimed in claim 1 , wherein, when the power reduction total value is greater than the predetermined value, the control unit calculates an upper limit value of a maximum transmission power by setting the power reduction value for adjusting the power class as 0 dB.
3. The terminal as claimed in claim 2 , wherein, when the power reduction total value is equal to or less than the predetermined value, the control unit calculates, as a value of the power reduction value, a value obtained by subtracting the power reduction total value from the predetermined value.
4. The terminal as claimed in claim 1 , wherein, when the power reduction total value is equal to or less than the predetermined value, the control unit calculates, as a value of the power reduction value, a value obtained by subtracting the power reduction total value from the predetermined value.
5. An uplink transmission method executed by a terminal, the method comprising:
a step of comparing a power reduction total value that is reduced from a maximum transmission power value determined based on a power class and that does not include a power reduction value for adjusting the power class with a predetermined value, and calculating a lower limit value of a maximum transmission power by setting the power reduction value for adjusting the power class as 0 dB when the power reduction total value is greater than the predetermined value; and
a step of performing uplink transmission using a maximum transmission power value equal to or greater than the lower limit value.
