WIPO Patent Application WO/2016/163641
Kind Code:
A1
Abstract:
A channel access method of an STA for UL MU transmission and an STA for performing the same are disclosed. The channel access method of the STA for the UL MU transmission may comprise the steps of: determining an access category of an uplink frame to be transmitted on the basis of UL MU OFDMA transmission by an STA; performing a channel access on the basis of a channel access parameter and resource unit configured according to the access category by the STA; and transmitting the uplink frame on a time resource, which overlaps with another uplink frame, to an AP on the basis of the UL MU OFDMA transmission by the STA, wherein the channel access parameter may include a CWmin value and a CWmax value for determining a size of a contention window for a channel access, and the resource unit may be a size of a frequency resource for the UL MU OFDMA transmission of the uplink frame.
