| Abstract(in English) | IEEE802.11ac can provide wide band communications that equals to or grater than 20 MHz from the channel bonding. For such wide band communications, a terminal needs to obtain more subchannels. In the ordinal Dynamic Bandwidth Channel Access scheme, ACK sent from the other terminal using the neighbored subchannel may prohibit from obtaining the subchannel. Then, the Delayed Dynamic Bandwidth ChannelAccess scheme provided proposed that when the terminal detects a frame which may be ACK, it will be delayed to obtain the subchannel after ACK+DIFS. However, if the detected frame is a fragment that continues successive fragment frames, then the terminal continues to wait for the successive frames. To solve this problem, this paper proposes the improvement of Delayed Dynamic Bandwidth Channel Access Scheme for fragments that when such situation is continued, the terminal communicatesat the primary channel as the ordinal Dynamic Bandwidth Channel Access scheme. The paper also explains about the simulation experiments to show the effectiveness of the proposed method. |
