Generation and detection of synchronization signal in a wireless communication system

An apparatus for wireless communication, comprising:

• at least one processor configured to generate a first sequence of a first length based on a first cyclic shift of a maximum length sequence (M-sequence), to generate a second sequence of the first length based on a second cyclic shift of the M-sequence, to generate an output sequence of a second length based on the first and second sequences, the second length being longer than the first length, and to generate a synchronization signal based on the output sequence.

A method for wireless communication, comprising:

• obtaining input symbols comprising a synchronization signal generated based on an output sequence of a first length, the output sequence being formed with first and second sequences of a second length corresponding to different cyclic shifts of a maximum length sequence (M-sequence), and the first length being longer than the second length;
• and
• processing the input symbols to detect for the first and second sequences.
