There is provided a method and corresponding device for transmitting a congestion indication to a group of wireless communication devices for synchronized triggering of backoff procedures in the wireless communication devices. A purpose of the synchronized triggering of the backoff procedures may be to enable deferring, in each of the wireless communication devices, transmission of scheduling request(s) until one or more backoff procedures in the considered wireless device is completed. In this way, the proposed technology provides efficient load control related to scheduling requests and/or enables a reduction of the average response time between scheduling request and grant.
