Abstract: A base station (100, 300) is provided with a transmitter and a receiver. The transmitter (109) transmits a downlink signal in a downlink transmission region, in a time unit that includes the downlink transmission region, an uplink transmission region, and a gap period that is a switching point between the downlink transmission region and the uplink transmission region. The receiver (111) receives an uplink signal in the uplink transmission region, in the time unit. Furthermore, a delay tolerant signal for which a delay is tolerated more than for the downlink signal and the uplink signal is mapped to within the gap period.

Abstract: A terminal includes: a circuit that, on the basis of a parameter of a first frequency resource assigned a reference signal (SRS) and a parameter of a second frequency resource, adjacent to the first frequency resource, that uses a subcarrier spacing (SCS) which is different from that used by the first frequency resource, punctures the reference signal at a boundary between the first frequency resource and the second frequency resource; and a radio transmitter that transmits the reference signal thus punctured.

Abstract: A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator (103) generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator (104) generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator (103). The wireless transmitter/receiver (106) transmits the Trigger frame, generated by the Trigger frame generator (104), to a terminal (200).
