FIELD: information technology.
SUBSTANCE: cell search is facilitated by user equipment (UE) in a wireless communication system. In one version, a primary synchronisation code (PSC) sequence may be generated based on a Frank sequence and a constant amplitude sequence which is repeated multiple times. In another version, a set of PSC sequences may be generated based on complementary sequences having good aperiodic correlation properties and efficient implementations. In another version, PSC sequences A+B and B+A may be formed based on Golay complementary sequences A and B, there "+" denotes concatenation. In yet another version, a set of secondary synchronisation code (SSC) sequences may be generated based on a set of base sequences and different modulation symbols of a modulation scheme. Each base sequence may be modulated by each of M possible modulation symbols for the modulation scheme to obtain M different SSC sequences.
EFFECT: shorter cell search time in a wireless communication system.
