20 Claims

1. A method performed by a terminal in a wireless communication system, the method comprising:

receiving, from a base station, a downlink signal of a plurality of downlink signals in a synchronization period, the downlink signal including a broadcast signal and a synchronization signal; and

identifying a position of the downlink signal in the synchronization period based on an index of the downlink signal in the synchronization period,

wherein the broadcast signal includes information indicating a position of the synchronization period in a frame including a plurality of subframes,

wherein the synchronization signal comprises a primary synchronization signal and a secondary synchronization signal that are received on different symbols, and

wherein the broadcast signal is scrambled based on the index of the downlink signal.
