Abstract
Systems and methods for blind detection of a numerology of a received signal are described. In one aspect, a method is provided for a user equipment (UE) to blindly detect the numerology of a received signal. The method includes correlating cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS) and determining a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses based on the correlated CP signals.
Claims18
A method for blind detection by a user equipment (UE) of one of possible multiple numerologies of a received signal, comprising:
- correlating cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS);
- measuring a power variation of the received signal in the frequency domain based on the plurality of hypotheses;
- and
- determining a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses based on the correlated CP signals based on the measured power variation.
A system for blind detection by a user equipment (UE) of one of possible multiple numerologies of a received signal, comprising:
- a memory;
- and
- a processor configured to:
- correlate cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS)
- measure a power variation of the received signal in the frequency domain based on a plurality of hypotheses of subcarrier spacing (SCS);
- and
- determine a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses based on the measured power variation.
