Abstract: The objective of the present invention is to suppress interference on an access point as a result of terminal-to-terminal communication. This terminal is provided with: a control circuit which performs transmission power control of a second link with another terminal, on the basis of a parameter relating to the state of a first link with an access point; and a transmitting circuit which transmits signals in accordance with the transmission power control.

Abstract: Provided is a terminal which can suitably transmit an uplink signal. In a terminal (100), a PC parameter control unit (104) sets a first power control parameter corresponding to a first service, when a prescribed condition relating to a control channel used for transmission of uplink signal allocation is met, and sets a second power control parameter corresponding to a second service, when the prescribed condition is not met. A transmission unit (109) transmits the uplink signal by using transmission power calculated by using the first power control parameter or the second power control parameter.

Abstract: In the present invention, a terminal can appropriately perform a random-access process. In a terminal (100), a wireless transmission unit (111) transmits a random-access signal including at least a data part. A rank determination unit (107) controls the configuration of the data part on the basis of a parameter regarding the transmission of the random-access signal.

Abstract: Provided is a radio communication device capable of reducing interference, caused by non-SR transmission, with a basic service set (BSS) performing spatial reuse (SR) transmission. An SR transmission resource control unit (107) of the radio communication device (SR initiator) (100) determines transmission resources for an SR signal to be transmitted by means of SR to a second BSS other than a first BSS to which the radio communication device (100) belongs on the basis of radio quality information transmitted from other radio communication devices (SR responders) in the first BSS. A radio transmission/reception unit (101) transmits the SR signal by using the determined transmission resources.

Abstract: According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (100), a repetition control unit (103) determines a data repetition pattern for a terminal (200). A transmission unit (109) repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal (200) by dynamic signaling.
