1. A user equipment (UE) in a wireless communication system, the UE comprising:

  • a transceiver configured to receive, from a base station (BS), a re-synchronization signal (RSS) over a downlink channel; and

    a processor operably connected to the transceiver, the processor configured to;

    identify time-domain and frequency-domain resources used for the RSS; and

    identify a sequence used for constructing the RSS from the time-domain and frequency-domain resources used for the RSS,wherein the sequence used for constructing the RSS is a quadrature phase shift keying (QPSK) modulated pseudo-noise (PN) sequence scrambled by a cover code and with an initial condition including at least part of a physical cell identification (ID).
