Abstract
To improve throughput in a communication environment in which a large number of terminal apparatuses access. The present invention includes a receiver configured to receive information indicating whether a radio resource allocated by a base station apparatus is a grant free access resource or a scheduled access resource as well as transmission power control information in the scheduled access resource (first transmission power control information) and transmission power control information in the grant free access resource (second transmission power control information); and a transmitter configured to transmit a transmission signal to the base station apparatus. In a case of communicating by using the scheduled access resource a transmission power control is performed based on the first transmission power control information to transmit the transmission signal and in a case of communicating by using the grant-free access resource the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.

10. A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:
a receiver configured to receive information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel; a transmitter configured to transmit a transmission signal to the base station apparatus by using the first resource or the second resource, wherein the information for indicating allocation of the first resource is indicated in downlink control information, the information for indicating allocation of the second resource is configured in advance by the base station apparatus, in a case of communicating by using the first resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal, and in a case of communicating by using the second resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.
11. The terminal apparatus according to claim 10, wherein the first transmission power control information includes a transmission power value or a transmission power control parameter, and in a case that the transmission power value is included, a transmission is performed at the transmission power, and in a case that the transmission power control parameter is included, the transmission is performed at a transmission power calculated based on the transmission power control parameter.
12. The terminal apparatus according to claim 10, wherein in a case of communicating by using the second resource, a transmission is performed at a transmission power obtained by adding a random power offset to a power calculated based on a transmission control parameter included in the second transmission power control information.
13. The terminal apparatus according to claim 10, wherein in a case of communicating by using the second resource, a power headroom is calculated that is a difference between a maximum transmission power and a transmission power calculated based on a transmission power control parameter included in the second transmission power control information, and in a case that the power headroom has a negative value, the terminal apparatus requests a scheduled access to the base station apparatus.
14. A base station apparatus for communicating with a terminal apparatus, the base station apparatus comprising:
a transmitter configured to transmit information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel; a receiver configured to receive a signal from the terminal apparatus by using the first resource or the second resource, the information for indicating allocation of the first resource is indicated by using downlink control information, the information for indicating allocation of the second resource is configured in advance, wherein, by using the first resource, the signal subjected to a transmission power control based on the first transmission power control information is received, and, by using the second resource, the signal subjected to the transmission power control based on the second transmission power control information is received.
15. The base station apparatus according to claim 14, wherein the first transmission power control information includes a transmission power value or a transmission power control parameter, and in a case that the transmission power value is included, the signal transmitted at the transmission power is received, and in a case that the transmission power control parameter is included, the signal transmitted at a transmission power calculated based on the transmission power control parameter is received.
16. The base station apparatus according to claim 14, wherein, by using the second resource, the base station apparatus receives the signal transmitted at a transmission power obtained by adding a random power offset to a power calculated based on a transmission control parameter included in the second transmission power control information.
17. A communication method of a terminal apparatus for communicating with a base station apparatus, the method comprising steps of:
receiving information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel; and transmitting a transmission signal to the base station apparatus by using the first resource or the second resource, wherein the information for indicating allocation of the second resource is indicated in downlink control information, the information for indicating allocation of the second resource is configured in advance by the base station apparatus, in a case of communicating by using the first resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal, and in a case of communicating by using the second resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.
18. A communication method of a base station apparatus for communicating with a terminal apparatus, the method comprising steps of:
