Patent ID: 8718034

Claim:
A method of facilitating synchronization between a base station (BS) and a user equipment (UE) in a mobile communication system, comprising: defining a set of cyclically permutable (CP) codewords, a plurality of cyclic shifts being derivable from each CP codeword, each cyclic shift being distinct from any other cyclic shift derivable from the set of CP codewords; selecting, by the BS, a CP codeword from the set; and encoding, by the BS, the selected CP codeword into a synchronization signal to be sent to the UE, the encoding being facilitated by a repetitive cyclically permutable (RCP) codeword derivable from the selected CP codeword, a plurality of cyclic shifts being derivable from the RCP codeword, each cyclic shift derivable from the RCP codeword being distinct from any other cyclic shift derivable from the RCP codeword, wherein the RCP codeword has a plurality of codeword elements each associated with a value, the value of at least one codeword element in the RCP codeword being repeated in another codeword element position in the RCP codeword.
