Abstract: Embodiments of this application provide a method and an apparatus for reducing co-channel interference, and a base station. The method includes: receiving, by a relay eNodeB ReNB, a propagation delay sent by a donor eNodeB DeNB, where the propagation delay is a delay of propagation between the DeNB and the ReNB; and adjusting, based on the propagation delay, timing parameters for sending uplink data and receiving downlink data by the ReNB, where the timing parameters are delays of the ReNB relative to the DeNB. The DeNB is used as a reference for the propagation delay between the DeNB and the ReNB, to delay timing of receiving the downlink data by the ReNB; and advance timing of sending the uplink data by the ReNB.
