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: A positioning method includes: sending, by a base station, indication information to a plurality of UEs, where the plurality of UEs have an MDT function in a cell covered by a to-be-positioned RRU, and the indication information is used to indicate the plurality of UEs to periodically report location information; obtaining, by the base station within each of at least one time period, time-of-arrival ToA measurement values of N UEs, where the N UEs are some UEs that report the location information in the plurality of UEs, N≥1, and N is an integer; and calculating, by the base station, a location of the to-be-positioned RRU based on M ToA measurement values obtained within the at least one time period and M pieces of location information that are in the received location information and that respectively correspond to the M ToA measurement values, where M≥3, and M is an integer.

Abstract: A lock screen display method includes: displaying, before a predetermined rule is triggered, for a plurality of lock screens, a lock screen with a high sequence level in a predetermined sequence on a screen of a mobile phone as a lock screen; determining, after the predetermined rule is triggered, a lock screen from the plurality of lock screens; and displaying the lock screen on the screen. A user can view information on a lock screen and operate the lock screen without unlocking the lock screens one by one.
