Abstract
User equipment UE (200) receives a demodulation reference signal from a network. The UE (200) restricts ports or combinations of the ports used for generation of the demodulation reference signal in a case of using a different frequency band different from a frequency band including one or a plurality of frequency ranges, or in a case of applying subcarrier spacing wider than subcarrier spacing for the case of using the frequency band.
Claims3
A terminal comprising:
- a receiver configured to receive a demodulation reference signal from a network;
- and
- a controller configured to restrict ports or combinations of the ports used for generation of the demodulation reference signal in a case of using a different frequency band different from a frequency band including one or a plurality of frequency ranges, or in a case of applying subcarrier spacing wider than subcarrier spacing for the case of using the frequency band.
A terminal comprising:
- a receiver configured to receive a plurality of types of demodulation reference signals from a network;
- and
- a controller configured to restrict the types of the demodulation reference signals in a case of using a different frequency band different from a frequency band including one or a plurality of frequency ranges, or in a case of applying subcarrier spacing wider than subcarrier spacing for the case of using the frequency band.
A terminal comprising:
- a receiver configured to receive a single-symbol demodulation reference signal or a double-symbol demodulation reference signal from a network;
- and
- a controller configured to restrict to either the single-symbol demodulation reference signal or the double-symbol demodulation reference signal in a case of using a different frequency band different from a frequency band including one or a plurality of frequency ranges, or in a case of applying subcarrier spacing wider than subcarrier spacing for the case of using the frequency band.
