Abstract
Disclosed are a frame transmission method and a communication device performing the same. The communication device may transmit a null data packet (NDP)-announcement (NDP-A) including information on a plurality of communication devices participating in interference alignment and transmit an NDP including a common signal field and a common training field commonly applied to the plurality of communication devices.
Claims12
A transmission method of a communication device, the method comprising:
- transmitting a null data packet announcement (NDP-A) frame after transmitting a NDP-start frame indicating start of transmission for the NDP-A frame;
- transmitting a null data packet (NDP) frame, after transmitting the NDP-A frame,
- wherein the communication device is participating in interference alignment.
A communication device comprising:
- one or more processor is configured to:
- transmit a null data packet announcement (NDP-A) frame after transmitting a NDP-start frame indicating start of transmission for the NDP-A frame;
- transmit a null data packet (NDP) frame, after transmitting the NDP-A frame,
- wherein the communication device is participating in interference alignment.
