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 communications method, apparatus, and system are disclosed. The method includes: generating, by an access device, a temporary identity sequence for a terminal, and sending a first message carrying the temporary identity sequence to the terminal; receiving, by the terminal, the first message sent by the access device, selecting one temporary identity from the temporary identity sequence, and generating, based on an area key of the terminal, the selected temporary identity, and a PDCP data SDU of the terminal, a PDCP data PDU of the terminal, which is used when a V2X message of the terminal is sent, where the area key is an area key of an area corresponding to location information of the terminal. This can implement security requirements of anonymity, non-traceability, and non-repudiation of V2X communication, and reduce security overheads and a processing delay of the V2X communication.

Abstract: The disclosure includes descriptions of methods and systems relate to a signal transmission mode switching method. On example method includes: when it is detected that signal transmission with a terminal device is abnormal, sending, to the terminal device, control instruction information that configures a signal transmission mode; and switching a current signal transmission mode to a to-be-switched-to signal transmission mode. The terminal device obtains, in a plurality of manners, a broadcast corresponding to the signal transmission mode to be switched to; determines, based on the broadcast, configuration information of the to-be-switched-to signal transmission mode; configures the to-be-switched-to signal transmission mode based on the configuration information; and then switches the current signal transmission mode to the to-be-switched-to signal transmission mode.
