Reference signals are described that are configured for use with extended carriers and / or carrier segments. The reference signal for the extended carrier and / or carrier segment may include a demodulation reference signal (e.g., a reference signal specific to the user equipment), a cell-specific reference signal, and a channel state information reference signal. A method, system and apparatus for constructing an extended carrier and / or carrier segment using a reference signal specific to a user equipment (e.g., locating one or more user equipment specific reference signal symbols on an extended carrier and / or a carrier segment) . |
