Abstract
The present invention is designed to appropriately configure sequences that are applied to reference signals and/or uplink control channels and so on in future radio communication systems. One aspect of the user terminal of the present invention provides a transmitting section that transmits a demodulation reference signal and/or an uplink control channel, to which predetermined sequences are applied, in predetermined slots, and a control section that controls each predetermined sequence that is used in the predetermined slots based on whether or not frequency hopping is used in the predetermined slots.
Claims19
A terminal comprising:
- a transmitter that transmits an uplink control channel to which a given sequence corresponding to a given group is applied;
- and
- a processor that determines the given group based on whether the uplink control channel is subjected to frequency hopping.
A radio communication method for a terminal, comprising:
- determining a given group based on whether an uplink control channel is subjected to frequency hopping;
- and
- transmitting the uplink control channel to which a given sequence corresponding to the given group is applied.
A terminal comprising:
- a transmitter that transmits a demodulation reference signal to which a given sequence corresponding to a given group is applied;
- and
- a processor that determines the given group based on a symbol number of the demodulation reference signal,
- wherein the processor determines at least the given group based on a first symbol number of the demodulation reference signal.
A radio communication method for a terminal, comprising:
- determining a given group based on a symbol number of a demodulation reference signal;
- and
- transmitting the demodulation reference signal to which a given sequence corresponding to the given group is applied,
- wherein the terminal further determines at least the given group based on a first symbol number of the demodulation reference signal.
A base station for communicating with a terminal comprising:
- a receiver that receives a demodulation reference signal from the terminal;
- and
- a processor that determines, for the demodulation reference signal to which a given sequence corresponding to a given group is applied, the given group based on a first symbol number of the demodulation reference signal.
A system comprising a terminal and a base station;
- wherein
- the terminal comprises:
- a transmitter that transmits a demodulation reference signal to which a given sequence corresponding to a given group is applied;
- and
- a processor of the terminal that determines the given group based on a symbol number of the demodulation reference signal,
- wherein the processor of the terminal determines at least the given group based on a first symbol number of the demodulation reference signal, and
- the base station comprises:
- a receiver that receives the demodulation reference signal from the terminal;
- and
- a processor of the base station that determines, for the demodulation reference signal to which a given sequence corresponding to a given group is applied, the given group based on a first symbol number of the demodulation reference signal.
