FIELD: electrical communication engineering.
SUBSTANCE: invention relates to communication networks. To avoid blocking unit queues in degraded MU EDCA mode due to OFDMA regular transmission of data from another queue in resource units provided by AP, multiple timers are used, each of which is associated with one of traffic queues, wherein each timer counts down a predetermined period during which the competition parameters remain fixed in the MU-EDCA parameters for the corresponding traffic queue before being set back to EDCA parameters different from the MU-EDCA parameters.
EFFECT: technical result of the invention is to provide more accurate control of the probability of sending single-user UL transmissions after multi-user UL transmission by setting parameters which form part of a set of EDCA parameters.
