Abstract
A terminal for communicating with a base station apparatus is disclosed, the terminal including a controller that sets maximum transmission power based on an Effective Isotropic Radiated Power (EIRP) of the terminal; and a transmitter that transmits an uplink signal based on the maximum transmission power. In other aspects, a communication method by a terminal for communicating with a base station apparatus is also disclosed.
Claims7
A terminal for communicating with a base station apparatus, the terminal comprising:
- a controller that sets maximum transmission power based on an Effective Isotropic Radiated Power (EIRP) of the terminal;
- and
- a transmitter that transmits an uplink signal based on the maximum transmission power, wherein the controller obtains the EIRP from an EIRP in a peak direction of a transmission beam of the uplink signal, and
- wherein the transmitter transmits information for reporting a power head room, using a Medium Access Control Control Element (MAC CE), including information on the maximum transmission power related to antenna gain in a direction in which the terminal is performing transmission.
