Abstract
A wireless communication method in a wireless network comprising an access point and a plurality of stations. The method includes selecting a transmission mode among a first and a second transmission modes, wherein access to a communication channel in the first transmission mode uses a contention mechanism with stations of the network, while access to the communication channel in the second transmission mode uses a preemption mechanism; sending a trigger frame to the stations using the selected transmission mode, the trigger frame reserving a transmission opportunity on at least one communication channel of the wireless network and defining resource units forming the communication channel and including a plurality of resource units that the stations can access for sending data; and receiving data from stations over the defined resource units.
