DISCOVERY SIGNALS AND NETWORK SYNCHRONIZATION SIGNALS DESIGN IN LTE
First Claim
1. A method of wireless communication for a user equipment (UE) comprising:
- receiving at least one of a first reference signal for at least one of discovery or measurement or a second reference signal for synchronization, the received at least one of the first reference signal or the second reference signal having a bandwidth configured by a base station (BS), wherein the received at least one of the first reference signal or the second reference signal is based on a Cell-Specific Reference Signal (CRS) or a Positioning Reference Signal (PRS); and
detecting at least one BS based on at least one of the first or second reference signals.

Abstract
Base stations (such as small cells) may support active and dormant states. To facilitate state transitions, these cells may transmit discovery signals. The transmission design of both discovery signals and network synchronization signals from small cells should provide for regular periodicity, while supporting the benefit of transitioning between active and dormant states. Disclosed is a method, a computer program product, and an apparatus that determine a first reference signal for at least one of discovery or measurement, and a second reference signal for synchronization, where both the first reference signal and the second reference signal are based on a same type of reference signal.
