1. A communication apparatus comprising:
circuitry, which, in operation, maps a sounding reference signal (SRS), which is a first delay tolerant signal, to a first gap period between a downlink transmission region and an uplink transmission region in a first time division duplex (TDD) subframe, and maps time unit configuration information to a second gap period in a second TDD subframe wherein the time unit configuration information, which is a second delay tolerant signal, dynamically indicates configuration of the first TDD subframe and a length of the first gap period in the first TDD subframe; and
a transmitter which, in operation, transmits the SRS,
wherein the communication apparatus does not perform an uplink transmission in the downlink transmission region and does not expect a downlink transmission in the uplink transmission region.
