A non-transitory computer readable medium including instructions stored thereon, which when executed by one or more processor(s) of a wireless communication station, cause a device to perform operations of: receiving, at the wireless communication station, one or more trigger frames from an access point, wherein each of the one or more trigger frames comprises allocation information for a transmission; causing to execute a first transmission attempt of data at the wireless communication station using a first transmission method and using the allocation information; determining the first transmission attempt of the data is unsuccessful; causing to execute one or more retransmission attempts of the data at the wireless communication station using the first transmission method and using the allocation information; determining the one or more retransmission attempts of the data are unsuccessful; determining a number of unsuccessful retransmission attempts of the data has met or exceeded a threshold; and causing to activate a second transmission method at the wireless communication station for executing a second transmission attempt of the data using the allocation information, wherein activating the second transmission method comprises: selecting a back-off count value (320, 330, 340, 360, 370) for the wireless communication station, wherein the back-off count value is an integer greater than zero that is selected at random; assigning the back-off count value to the wireless communication station; decrementing the back-off count value by one for identification of each random access-enabled resource unit comprised in the one or more trigger frames received from the access point; and causing to execute the second transmission attempt of the data using the second transmission method when the back-off count value reaches zero. receiving, at the wireless communication station, one or more trigger frames from an access point, wherein each of the one or more trigger frames comprises allocation information for a transmission; causing to execute a first transmission attempt of data at the wireless communication station using a first transmission method and using the allocation information; determining the first transmission attempt of the data is unsuccessful; causing to execute one or more retransmission attempts of the data at the wireless communication station using the first transmission method and using the allocation information; determining the one or more retransmission attempts of the data are unsuccessful; determining a number of unsuccessful retransmission attempts of the data has met or exceeded a threshold; and causing to activate a second transmission method at the wireless communication station for executing a second transmission attempt of the data using the allocation information, wherein activating the second transmission method comprises: selecting a back-off count value (320, 330, 340, 360, 370) for the wireless communication station, wherein the back-off count value is an integer greater than zero that is selected at random; assigning the back-off count value to the wireless communication station; decrementing the back-off count value by one for identification of each random access-enabled resource unit comprised in the one or more trigger frames received from the access point; and causing to execute the second transmission attempt of the data using the second transmission method when the back-off count value reaches zero. selecting a back-off count value (320, 330, 340, 360, 370) for the wireless communication station, wherein the back-off count value is an integer greater than zero that is selected at random; assigning the back-off count value to the wireless communication station; decrementing the back-off count value by one for identification of each random access-enabled resource unit comprised in the one or more trigger frames received from the access point; and causing to execute the second transmission attempt of the data using the second transmission method when the back-off count value reaches zero.
