FIELD: information technologies.
SUBSTANCE: subscriber terminal receives an alarm of a physical channel for control of a line "downwards" from the system; from the subsequent subframes of a subframe that has received the alarm of the physical channel for control of the line "downwards", this terminal detects the first subframe, which meets the condition A and contains PRACH resources, as well. The condition A means that the time shift between the first subframe and the subframe that has received the alarm of the physical channel for control of the line "downwards" is more or equal to k, where k - the specified time delay on the physical level of the described terminal; from this first subframe this subscriber terminal starts selecting subframes, containing resources of random access.
EFFECT: successful realisation of random access.
