Abstract:
Disclosed are a beam scanning method and a base station, the method in which generated is a code book comprising a plurality of second precoders, defined by the weighted sums of a plurality of first precoders, and in which a plurality of synchronization signals, to which applied are second precoders that are selected from the code book and differ from each other, are transmitted to a terminal over a plurality of time intervals. The synchronization signals are used in synchronization, beam scanning and cell ID acquisition of the terminal, and each weighted sum applied to the plurality of first precoders indicates a beam ID used in the beam scanning.

Claim (Index 1):
A method of performing beam scanning, which is performed by a base station with a user equipment (UE) in a wireless communication system, the method comprising:\n generating a codebook consisting of a plurality of second precoders defined by weighted sums of a plurality of first precoders; and transmitting to the UE over a plurality of time intervals, a plurality of synchronization signals to which second precoders different from each other selected from the codebook are applied, wherein the synchronization signals are used for a synchronization procedure, a beam scanning procedure, and a cell ID acquisition procedure of the UE, and wherein each of the weighted sums applied to a plurality of the first precoders corresponds to a beam ID utilized for the beam scanning procedure.
