A reference signal configured for use with an extended carrier and / or carrier segment is described. Reference signals for extended carriers and / or carrier segments may include demodulation reference signals (eg, user equipment specific reference signals), cell specific reference signals, and channel state information reference signals. Method, system for configuring an extended carrier and / or carrier segment using a user equipment specific reference signal (eg, positioning one or more user equipment specific reference signal symbols in the extended carrier and / or carrier segment) , And apparatus are described. |
