Terminal device, communication method, and integrated circuit
First Claim
1. A terminal device that communicates with a base station device, comprising:
- reception circuitry that receives first information related to a first configuration and/or second information related to a second configuration; and
transmission circuitry that;
transmits an uplink signal based on a first uplink power control in a first case where the first information related to the first configuration is received, and the second information related to the second configuration is not received, andtransmits the uplink signal based on a second uplink power control in a second case where the first information related to the first configuration and the second information related to the second configuration are both received, whereinthe first information related to the first configuration indicates a Time Division Duplex Uplink/Downlink (TDD UL/DL) configuration of uplink subframes for the uplink signal and downlink subframes for a downlink signal,the second information related to the second configuration is a bit map that indicates either one of a first subframe set and a second subframe set for each of the subframes,in the first uplink power control, the transmission circuitry determines a transmission power of the uplink signal based on a first power control parameter set, andin the second uplink power control, the transmission circuitry determines the transmission power on a first subframe of the first subframe set based on the first power control parameter set, and determines the transmission power on a second subframe of the second subframe set based on a second power control parameter set.

Abstract
In a communication system in which a base station device (1) and a terminal device (2) communicate, there is a provided a terminal device, a method, and an integrated circuit enabling the base station device (1) and the terminal device (2) to conduct transmit power control efficiently. Provided is a terminal device that communicates with a base station device, including a transmission unit that transmits an uplink signal based on a first uplink power control in a case of the information related to the first configuration being configured, and the information related to the second configuration not being configured, and transmits an uplink signal based on a second uplink power control in a case of the information related to the first configuration and the information related to the second configuration both being configured.
