Abstract  Abstract

can be used as the component carrier of a particular type of secondary cell in an LTE system is been reduced or eliminates new types of traditional control signaling (e.g. CRS) carrier is omitted. The invention claims for when there is no CRS in the component carrier downlink between the eNB and the UE is performed in replacing technology of timing and frequency synchronization. These techniques involve using the channel status information reference signal or a UE specific reference signal.

A particular kind of component carrier that may be used as a secondary cell in an LTE system is a new type carrier that has reduced or eliminated legacy control signaling such as the omission of CRSs. Alternative techniques are described for performing timing and frequency synchronization in the downlink between an eNB and a UE when CRSs are not present in a component carrier. These techniques involve using either channel state information reference signals or UE-specific reference signals.
