Abstract: [Object] Provided is a communication apparatus that performs radio communication of data without exchanging control information in advance. [Solving Means] A communication apparatus includes: a communication unit that transmits and receives a radio signal; a determination unit that determines a radio resource to be used by the communication unit; and a control unit that controls an operation of transmitting and receiving a radio signal by the communication unit on the basis of the radio resource determined by the determination unit, in which the determination unit determines a radio resource used for transmission of a radio signal according to a radio resource determination rule corresponding to a desired transmission period, and the control unit performs control so that the radio signal is transmitted from the communication unit at the desired transmission period.

Abstract: The present technique relates to a wireless communication device and a wireless communication method for enabling acquisition of control information even when a preamble signal cannot be acquired. The wireless communication device includes an OFDM signal generation section that generates an OFDM signal in which at least one of plural resource units obtained by channel band division is set as a control information resource unit for transmitting control information. The present technique is, for example, applicable to a wireless communication device, etc. that performs wireless communication conforming to a standard such as IEEE 802.11.

Abstract: There is provided a communication device that determines a wireless resource for a downlink without performing signaling between a base station and a terminal. A communication device includes a communication unit that transmits and receives a wireless signal, and a wireless resource determination unit that determines a wireless resource used for transmission and reception. The wireless resource determination unit determines, in a communication system including a base station and a terminal, on the basis of a common rule between the base station and the terminal, a plurality of candidates for the wireless resource to be used for downlink communication in the slot for each terminal, and then selects the plurality of candidates for each terminal one by one in such a manner that wireless resources do not overlap between the terminals.
