摘要：
A communication system, a communication device and a communication method, to achieve a reduction in communication time. When performing communication in passive mode, the initiator transmits a polling request frame where a first value is set in time slot information, and when performing communication in simple mode, the initiator transmits a polling request frame where a second value different from the first value is set in time slot information. When the time slot information included in the polling request frame from the initiator has the first value, the target transmits a polling response frame including an ID for identifying the target at the timing of a time slot determined by a random number, and when the time slot information has the second value, the target transmits a polling response frame including real data at the timing of a time slot set in advance.
