Method and apparatus having a synchronization signal sequence structure for low complexity cell detection

A user equipment in a communication network including one or more potential respective communication targets from which a synchronization signal can be received, the user equipment comprising:

• a controller that establishes a set of a plurality of synchronization signal sequences, where each of the synchronization signal sequences from the set is to be used in connection with a different one of the potential respective communication targets, and where each one of the plurality of synchronization signal sequences comprises
• 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,
• where the second preselected sequence is different than the first preselected sequence, and is different than the complex conjugate of the first preselected sequence, and
• where 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, and the length of the first sub-sequence is the same as the length of the second sub-sequence;
• and
• a transceiver that receives a signal including a synchronization signal, where the synchronization signal comprises one of the synchronization signal sequences from the set of the plurality of synchronization signal sequences;
• and
• wherein the controller further detects a particular one of the synchronization signal sequences of the set of the plurality of synchronization signal sequences for use in identifying a particular one of the potential respective communication targets.
