Patent ID: 10057030

Abstract:
The present disclosure discloses a method used in a UE for estimating a frequency offset between a CRS of a serving cell of the UE and a DM-RS of a data transmission to be decoded by the UE, using a set of quasi-co-located reference signals. The method comprises: comparing a number of Resource Blocks, RBs, for the data transmission to a first threshold; selecting one or more quasi-co-located reference signals from the set of quasi-co-located reference signals based on a result of the comparison; and estimating the frequency offset based on the selected one or more quasi-co-located reference signals. The present disclosure also relates to a UE for estimating a frequency offset between a CRS of a serving cell of the UE and a DM-RS of a data transmission to be decoded by the UE, using a set of quasi-co-located reference signals.
