Terminal device, base station device, communication method, and integrated circuit

摘要

According to the present invention, there are provided a base station device, a terminal device, a communication method, and an integrated circuit capable of performing communication more efficiently when the terminal device transmits an uplink signal based on scheduling by the base station device. The terminal device includes a setting unit that sets a first uplink-downlink configuration, a second uplink-downlink configuration, and a third uplink-downlink configuration, a reception unit that monitors a physical downlink control channel accompanied with a downlink control information format which is used to schedule a physical downlink shared channel in a downlink subframe based on the third uplink-downlink configuration and includes information making a request for transmitting a sounding reference signal, and a transmission unit that transmits or drops the sounding reference signal and transmit an HARQ-ACK for transmission with the physical downlink shared channel.

主权项

1. A terminal device configured to communicate with a base station device, the terminal device comprising:
reception circuitry configured to
receive an RRC message including first information indicating an uplink-downlink configuration,receive, on a physical downlink control channel, second information indicating an uplink-downlink configuration, andreceive a random access response; and transmission circuitry configured to perform, in a subframe indicated as an uplink subframe by the uplink-downlink configuration based on the second information, transmission on a physical uplink shared channel that is based on decoding of a physical downlink control channel with a CRC scrambled by a C-RNTI, wherein the transmission circuitry is configured to perform, based on information included in the random access response, transmission on a physical uplink shared channel in an uplink subframe based on the uplink-downlink configuration indicated by the first information.
