Abstract
A method, base station, and relay device for receiving physical uplink control information are disclosed in the present invention. The method includes: selecting a PUCCH resource of the relay, where the PUCCH resource can form multiplexing with a first resource, and the first resource includes the PUCCH resource occupied by a 3GPP LTE terminal when the terminal transmits the physical uplink control information in a first format; determining a channel index corresponding to the PUCCH resource of the relay; transmitting notification information to the relay, where the notification information includes the channel index; and receiving the physical uplink control information transmitted, according to the channel index, by the relay. In the embodiments of the present invention, the interference between the PUCCH format 1/1a/1b channel of the relay and that of the LTE R8 terminal is effectively reduced.
