COMMUNICATION DEVICE AND SRS TRANSMISSION CONTROL METHOD

摘要

Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an “SRS Transmission Execution Rule” and the reception status of trigger information.

主权项

1. A communication apparatus comprising:
circuitry, which, in operation, detects control information indicating whether or not to request transmission of a sounding reference signal (SRS) and indicating a transmission parameter of the SRS; and a transmitter, which, in operation, transmits the SRS based on the detected control information, wherein, when the circuitry detects the control information twice or more within a predetermined period, the circuitry detects the control information, which indicates an identical transmission parameter, within the predetermined period.
