<P>PROBLEM TO BE SOLVED: To provide techniques and an apparatus for establishing direct link setup (DLS) connections between stations in a wireless local area network (WLAN) so as to avoid collisions with transmissions from hidden stations. <P>SOLUTION: There is provided a method that comprises: sending a ready-to-send (RTS) frame by a first station, directed to an access point within a basic service set (BSS); receiving a clear-to-send (CTS) frame sent from the AP in response to the RTS, where at least one of the RTS and CTS frames have duration fields set to accommodate expected data frame transmissions from the first station to a second station in the BSS on the DLS connection; and exchanging, by the first station, data frames directly with the second station on the DLS connection. <P>COPYRIGHT: (C)2013,JPO&INPIT |
