    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.

    Abstract: The present disclosure relates to mobile communications technologies, and in particular, to a mobile communication method, apparatus, and device. The method includes receiving, by a user equipment (UE), a non-access stratum (NAS) security mode command message from a mobility management entity MME, where the NAS security mode command message carries first verification matching information used to verify UE capability information received by the MME. Based on the first verification matching information, the UE determines whether the UE capability information received by the MME is consistent with UE capability information sent by the UE to the MME. In response to determining that the UE capability information received by the MME is consistent with the UE capability information sent by the UE to the MME, the UE sends a NAS security mode complete message to the MME.
