Abstract

In a case of using a different frequency band that is different from a frequency band including one or a plurality of frequency ranges, a terminal sets an initial access channel configured with a smaller number of resource blocks than in a case of using the frequency band. The terminal transmits an initial access signal via the set initial access channel.

Claims (8)

1 . A terminal comprising:

a processor that sets, in a case of using a different frequency band beyond a frequency band including a frequency range between 410 MHz and 7.125 GHz and a frequency range between 24.25 GHz and 52.6 GHz, an initial access channel configured with a smaller number of resource blocks than in a case of using the frequency band; and

a transmitter that transmits an initial access signal via the initial access channel,

wherein the processor sets the initial access channel with a smaller number of the resource blocks as a subcarrier spacing is increased.

2 . The terminal according to claim 1 , wherein the processor sets the initial access channel having a shorter sequence length than in a case of using the frequency band.

3 . The terminal according to claim 1 , wherein the transmitter transmits the initial access signal with less resources in a time direction than in a case of using the frequency band.

4 . The terminal according to claim 3 , wherein the transmitter transmits the initial access signal with increased resources in a frequency direction than in a case of using the frequency band.

5 . The terminal according to claim 1 , wherein the processor sets, in a case where the processor assumes a minimum subcarrier spacing of 240 kHz, the initial access channel with a smaller number of the resource blocks as a subcarrier spacing is increased.
