Communication method, communication apparatus and communication system configured to determine whether a reserved period is between two data or signals

A first communication apparatus comprising:

• circuitry, which in operation,
• reserves one or more blanked periods between two consecutive signals in a first case where a first condition and other conditions are met, wherein the first condition is that a subcarrier spacing of the two consecutive signals is larger than or equal to a threshold, and
• reserves no blanked period between the two consecutive signals in a second case where the first condition is not met and the other conditions are met;
• and
• a transmitter, which in operation, transmits the two consecutive signals to a second communication apparatus.

A communication method performed at a first communication apparatus, the communication method comprising:

• reserving one or more blanked periods between two consecutive signals in a first case where a first condition and other conditions are met, wherein the first condition is that a subcarrier spacing of the two consecutive signals is larger than or equal to a threshold;
• reserving no blanked period between the two consecutive signals in a second case where the first condition is not met and the other conditions are met;
