Abstract
In a terminal, a selecting unit selects one generation method from a plurality of generation methods for reference signals (sounding reference signals (SRSs)). A radio transmitting unit transmits reference signals (SRSs) generated in accordance with the selected generation method.
Claims14
A terminal comprising:
- circuitry, which, in operation,
- determines a number of terminals which transmit reference signals in a partial band of a system band;
- in response to the number of terminals being less than a threshold value, selects one generation method from a plurality of generation methods for reference signals, the plurality of generation methods including a first generation method by which each of the reference signals is generated by using one code sequence and a second generation method by which each of the reference signals is generated by concatenating one or more code sequences, and
- in response to the number of terminals being not less than the threshold value, selects another generation method from the plurality of generation methods;
- and
- a transmitter, which, in operation, transmits the reference signals generated in accordance with the selected generation method.
