1. An uplink MU-MIMO method, wherein the method comprises:

  • receiving, by a base station, sounding reference signals sent by multiple user equipments, wherein the multiple user equipments meet a short-distance transmission condition;

    constructing, by the base station, a precoding matrix according to the received sounding reference signals;

    generating, by the base station, a first scheduling message according to the precoding matrix;

    sending, by the base station, the first scheduling message to the multiple user equipments, so as to schedule at least one user equipment in the multiple user equipments to generate at least one MAC packet data unit (MAC PDU), and exchange the MAC PDUs between the multiple user equipments by using a short-distance transmission technology; and

    receiving, by the base station after a preset fixed time, uplink signals sent by the multiple user equipments, wherein the uplink signals are uplink signals generated after the multiple user equipments separately process the MAC PDUs.
