Patent ID: 11368344

Abstract:
A method and apparatus having a synchronization signal sequence structure for low complexity cell detection is provided. The method includes establishing a set of a plurality of synchronization signal sequences to be used in connection with a communication target. Each one of the plurality of synchronization signal sequences includes at least a first sub-sequence, which includes either a first preselected sequence or a complex conjugate of the first preselected sequence, and a second sub-sequence, which includes either a second preselected sequence or a complex conjugate of the second preselected sequence. The second preselected sequence is different than the first preselected sequence, and is different than the complex conjugate of the first preselected sequence. Further, a length of the first sub-sequence and a length of the second sub-sequence are smaller than a length of the synchronization signal sequence. A signal including a synchronization signal is then received, where the synchronization signal comprises one of the synchronization signal sequences from the set of the plurality of synchronization signal sequences, and the synchronization signal is then detected.
