摘要：A random access method and a related apparatus are disclosed. The method includes: receiving first signaling, which is sent by a base station to an eIMTA user equipment through a physical downlink shared channel PDSCH, and receiving second signaling, which is sent by the base station to the eIMTA user equipment through a physical downlink control channel PDCCH or an enhanced physical downlink control channel ePDCCH, where the first signaling includes a first time division duplexing TDD uplink-downlink configuration, and the second signaling includes a second TDD uplink-downlink configuration; determining, by the eIMTA user equipment according to the first TDD uplink-downlink configuration, an uplink subframe for sending a random access message 3; and sending, by the eIMTA user equipment, the random access message 3 to the base station in the determined uplink subframe. A corresponding apparatus is further disclosed. Both a non-eIMTA user equipment and an eIMTA user equipment send random access messages 3 by uniformly using an uplink subframe determined according to an uplink-downlink configuration that is included in signaling sent through a physical downlink shared channel, so that a base station can accurately receive the random access messages 3 sent by the non-eIMTA user equipment and the eIMTA user equipment.
