Abstract
A method and system for acquiring mmWave carrier in a wireless communication network is disclosed. In one embodiment, an MS acquires a low frequency carrier and then acquires the high frequency carrier. Since the low frequency carrier and the high frequency carrier are transmitted by same BS, the BS provides assistance information on the acquired low frequency carrier to the MS to acquire a synchronization signal which is transmitted on a high frequency carrier using beamforming. The assistance information includes synchronization signal beam time slots, synchronization signal beams which the MS needs to search, beam ID and so on. Based on the assistance information, the MS monitors the high frequency carrier to search and acquire the synchronization beam signal transmitted on the high frequency carrier. The MS determines the beam ID of the received synchronization beam signal and reports to the BS on the low frequency carrier.
