Abstract  Abstract

PROBLEM TO BE SOLVED: To prevent deterioration in throughput by reducing possibility of occurrence of mis-recognition between a base station and a terminal of the existence of SRS transmission or SRS resources.

SOLUTION: A terminal (200) includes: a reception processing unit (203) for detecting control information showing whether or not to request transmission of a sounding reference signal (SRS); and a transmission signal formation unit (207) for transmitting an A-SRS according to a transmission control unit (206) performing control based on the control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of a SRS transmission execution rule and a reception situation of trigger information. For example the SRS transmission execution rule shows transmission of the SRS according to allocation control information including trigger information indicating a transmission request detected first in a valid period.
