Document Type and Number:
WIPO Patent Application WO/2010/085093
Kind Code:
A3
Abstract:
A method and apparatus of determining a slot time in a contention based communication network is provided. An access point(AP)receives a transmission mode field indicating whether each of a plurality of stations supports directed transmission from each of the plurality of stations constituting a basic service set (BSS), determines the slot time for attempting contention-based access on the basis of the transmission mode field obtained from each of the plurality of stations constituting the BSS, and transmits a mode field comprising the slot time to the plurality of stations constituting the BSS.
