Abstract
When a plurality of the subcarrier spacing values are applied, a reference signal is generated by using a sequence having a sequence length corresponding to a first ratio of a first subcarrier spacing set for transmission data to the maximum settable subcarrier spacing. The sequence of the reference signal is mapped to a frequency resource at mapping intervals in accordance with a second ratio which is the reciprocal of the first ratio, and the transmission data and the reference signal are transmitted.
Claims11
A transmission device comprising:
- circuitry, which, in operation:
- generates a reference signal by using a sequence having a sequence length corresponding to a ratio of a configured subcarrier spacing to the maximum configurable subcarrier spacing;
- and
- maps the reference signal to subcarriers at determined intervals;
- and
- a transmitter, which, in operation, transmits the reference signal,
- wherein the determined intervals have a length that is a reciprocal of the ratio.
A transmission device comprising:
- circuitry, which, in operation:
- generates a reference signal by using a sequence in a system where a subcarrier spacing is variable;
- and
- maps the reference signal to subcarriers;
- and
- a transmitter, which, in operation, transmits the reference signal,
- wherein a sequence length of the sequence is based on a length of an OFDM symbol in the maximum configurable subcarrier spacing.
A transmission method comprising:
- generating a reference signal by using a sequence having a sequence length corresponding to a ratio of a configured subcarrier spacing to the maximum configurable subcarrier spacing;
- mapping the reference signal to subcarriers at determined intervals;
- and
- transmitting the reference signal,
- wherein the determined intervals have a length that is a reciprocal of the ratio.
A transmission method comprising:
- generating a reference signal by using a sequence in a system where a subcarrier spacing is variable;
- mapping the reference signal to subcarriers;
- and
- transmitting the reference signal,
- wherein a sequence length of the sequence is based on a length of an OFDM symbol in the maximum configurable subcarrier spacing.
