FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used to support cell search in a wireless communication system. The device for supporting cell search comprises a processor which is configured to send a primary synchronisation transmission in a first location of a frame, wherein the first location is non-overlapping with at least one other location used for at least one other primary synchronisation transmission sent by at least one neighbouring cell, and to send additional synchronisation transmission in a second location of the frame, and a storage device connected to the processor, wherein primary and additional synchronisation transmissions are formed based on one of multiple cyclic prefix lengths.
EFFECT: shorter search time and low probability of false detection.
