FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless communication system, and in particular to the method and device to transfer and reception of control information in a wireless communication system. The method to transfer control information includes masking of control with the help of a cyclic redundant code (CRC) with the help of a CRC mask, including a bit stream of predetermined length and an indicator indicating a bit stream, and transfer of control information including a masked CRC at least to one mobile station (MS). The indicator indicates whether a bit stream included into a CRC mask contains a random access identifier (RAID).
EFFECT: provision of efficiency of reception of control information.
