1. A method performed by a user equipment (UE), comprising: receiving a physical cell identifier information element (IE) from an evolved node B (eNB), wherein the physical cell identifier IE is associated with a secondary cell (SCell) that is on an unlicensed Long-Term Evolution (LTE) carrier frequency; determining a physical-layer cell identity (PCI) of the SCell based on the physical cell identifier IE; and applying the PCI as a parameter for physical channels or signals on the SCell; wherein the UE assumes: primary synchronization signal (PSS) and secondary synchronization signal (SSS) in a primary cell (PCell) are transmitted every 5 milliseconds, and PSS and SSS in the SCell are not transmitted every 5 milliseconds but only in some occasions.
