Title:
LINK ADAPTATION AND DEVICE IN ACTIVE SCANNING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/069906
Kind Code:
A1
Abstract:
Disclosed are a link adaptation method and device in an active scanning method. The link adaptation method transmits a probe request frame comprising null data packet announcement (NDPA) information elements, transmits a null data packet(NDP) frame comprising only a physical layer convergence protocol(PLCP) header after transmitting the probe request frame, and receives a probe response frame comprising feedback information elements measured based on the NDP frame.
Therefore, the invention is capable of improving data transmission efficiency by using a modulation coding scheme (MCS) suitable for a channel state from initial connection.
