Abstract
A time division duplex (TDD) user equipment (UE) is configured to synchronize to a TDD base station. The UE includes a receiver configured to receive a primary synchronization code along with a plurality of secondary synchronization codes from a TDD base station. The TDD base station is associated with having a code group out of N code groups. The plurality of secondary synchronization codes number less than (logN)+1 and are quadrature phase shift keying modulated. The UE also includes a corresponding matched filter to each of the received secondary synchronization codes. The UE is configured to identify the code group of the TDD base station by the received plurality of secondary synchronization.
