Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for including a tracking reference signal (TRS) in a downlink subframe, the method comprising: determining whether at least one of a time density or a frequency density of a channel-state-information reference signal (CSI-RS), included in the downlink subframe for at least one of time or frequency tracking by an user equipment, exceeds a threshold; generating, in response to determining that the at least one of the time density or the frequency de…
