摘要： The present invention relates to a method and device for channel measurement in a wireless LAN system. A station (STA) receives a plurality of sounding frames from an access point (AP), estimates the plurality of sounding frames in order to generate long-term channel state information (LCSI), provides the generated LCSI to the AP as feedback, and receives from the AP a group identifier (ID) management frame comprising information on a group ID determined on the basis of the LCSI.

摘要： Methods and compositions for suppressing gall formation in plant cells induced by Agrobacterium infection are disclosed. The methods involve introducing at least one DNA construct, encoding at least one untranslatable sense-strand RNA and/or double-stranded RNA, into a plant cell. Introduction of these molecules into the plant cell causes the plant cells to become resistant to gall formation.
