Abstract:
Provided are a communication device and a communication method that perform direct communication between terminals.
A communication device that operates as a terminal under control of a base station, includes: a communication unit that transmits and receives wireless signals; and a control unit that controls transmission of data using a predetermined resource pool by the communication unit. The control unit determines implementation of relay communication for a packet within the predetermined resource pool on the basis of at least one of information received from the base station, information received from another terminal, or information obtained from the terminal itself, during packet reception, and performs the relay communication by using a resource secured by a transmission source terminal, the terminal itself, or the base station.
