COMMUNICATION DEVICE AND COMMUNICATION METHOD, COMPUTER PROGRAM, AND COMMUNICATION SYSTEM

摘要

The throughput of the entire system is improved by increasing the number of communication stations which can communicate at the same time while implementing directional communication by millimeter waves. Beamforming of a transmission beam is performed not only on a data frame but also on a CTS frame. When the direction of a transmission/reception beam of a hidden terminal (STA_C) is different from the direction of a data transmission side (STA_A) with respect to a data reception side (STA_B), the hidden terminal (STA_C) does not receive the CTS, and thus can continue an operation of communicating with a communication partner terminal (STA_D) without setting a transmission stop period.
