Abstract
Embodiments herein provide a method of performing a cell search by user equipment (UE). The method includes receiving a signal from the base station. The method includes estimating a fractional frequency offset (FFO) along with a coarse timing using a cyclic prefix (CP) in the received signal. The method includes compensating the received signal with the estimated FFO. Further, the method includes applying a correlation on the compensated received signal with each of a plurality of primary synchronization signals (PSSs) generated by the UE. Furthermore, the method includes determining a plurality of cell search parameters based on the applied correlation.
Claims8
A method of performing a cell search by a user equipment (UE), the method comprising:
- receiving a signal from a base station;
- estimating a fractional frequency offset (FFO) along with a coarse timing using a cyclic prefix (CP) in the received signal;
- compensating the received signal with the estimated FFO;
- applying a correlation on the compensated received signal with each of a plurality of primary synchronization signals (PSSs) generated at the UE;
- determining a plurality of cell search parameters based on the applied correlation;
- determining that the plurality of cell search parameters are unavailable;
- applying a correlation on the received signal with each of the plurality of primary synchronization signals (PSSs) to eliminate each value from a candidate set of values considered for integer frequency offset (IFO) to determine IFO;
- and
- determining the plurality of cell search parameters based on the correlation.
A user equipment (UE) for performing a cell search, the UE comprising a receiver configured to:
- receive a signal from a base station;
- estimate a fractional frequency offset (FFO) along with a coarse timing using a cyclic prefix (CP) in the received signal;
- compensate the received signal with the estimated FFO;
- apply a correlation on the compensated received signal with each of a plurality of primary synchronization signals (PSSs) generated at the UE;
- determine a plurality of cell search parameters based on the applied correlation;
- determine that the plurality of cell search parameters are unavailable;
- apply a correlation on the received signal with each of the plurality of primary synchronization signals (PSSs) to eliminate each value from a candidate set of values considered for integer frequency offset (IFO) to determine IFO;
- and
- determine the plurality of cell search parameters based on the correlation.
