Abstract
A method and an apparatus in a base station are capable of including a tracking reference signal (TRS) in a downlink subframe. The method includes generating a TRS subframe by including the TRS in the downlink subframe at a frequency density of at least one resource element per six resource elements in the TRS subframe. Additionally, the method includes transmitting the TRS subframe at a periodicity among other subframes not including the TRS.
