Abstract
In the multiple short sequence based SRS, multiple items of sequence data having a short sequence length corresponding to a partial band are used for transmitting SRS in discontinuous bands. In the multiple short sequence based SRS, a terminal specifies a frequency domain to be used for transmitting a reference signal using predetermined sequence data, applies a phase shift index associated with the specified frequency domain to the reference signal, and transmits the reference signal to which the phase shift index is applied by using the specified frequency domain.
Claims18
A base station comprising:
- circuitry, which, in operation, allocates a frequency region including a plurality of frequency resources to a terminal;
- and
- a receiver, which, in operation, receives a signal, which is generated based on both a plurality of cyclic shift indexes that are associated with the plurality of frequency resources, respectively, and another cyclic shift index that is configured per terminal, and which is transmitted from the terminal.
A communication method comprising:
- allocating a frequency region including a plurality of frequency resources to a terminal;
- and
- receiving a signal, which is generated based on both a plurality of cyclic shift indexes that are associated with the plurality of frequency resources, respectively, and another cyclic shift index that is configured per terminal, and which is transmitted from the terminal.
