WLAN NODES, AND METHODS THEREIN FOR EFFICIENT USAGE OF WLAN RESOURCES

摘要

A first Wireless Local Area Network (WLAN) node (212) and a method therein for performing a transmission to a second WLAN node (214) in a WLAN (200).The first WLAN node identifies a third WLAN node (222) transmitting a first signal (S1) overheard by the first WLAN node, and determines to transmit, to the second WLAN node, a second signal (S2) based on the identity of the third WLAN node and on a received power of the first signal. When determined to transmit the second signal, the first WLAN node determines a Modulation and Coding Scheme (MCS) index value by means of a link adaptation process specific for the identified third WLAN node and transmits to the second WLAN node,the second signal using the determined MCS index.
