[Object] To provide a receiving apparatus in a wireless communication system and a channel estimation control method that are capable of reducing delay in channel estimation and the error rate in decoding channel information. [Solving Means] In a wireless communication system using a first reference signal, with which a control information signal is not multiplexed, and a second reference signal, with which a control information signal is multiplexed, a receiver (200) includes: an A/N detection selection unit (211) that selects whether to use both the first reference signal and the second reference signal for channel estimation or to use only the first reference signal for channel estimation; and a channel estimation unit (209) that carries out channel estimation by use of the selected reference signal(s). |
