ABSTRACT:
An apparatus and a method for presenting a novel format of a media access control (MAC) frame that enables the use of a direct link protocol (DLP) and multiple channels, thereby reducing contention among stations, and enhancing a transfer rate by using the MAC frame format in infrastructure-based wireless communications. A DLP station of the present invention includes a channel-switching module for switching a channel by writing a new channel number in a DLP request frame; a mode-switching module for switching a DLP mode by writing a new mode number in the DLP request frame; and a MAC frame-generating module for generating various MAC frames including the DLP request frame.
