Abstract: The present application provides an uplink transmission method and apparatus. A terminal receives a plurality of reference signals sent by a network device, and measures signal quality of the plurality of reference signals, so as to select a beam corresponding to one reference signal (i.e., a second reference signal) from the plurality of reference signals as a downlink beam. In addition, a terminal can also indicate, in the measurement report, an uplink beam corresponding to a first reference signal in the plurality of reference signals. In other words, the terminal can search for two beams and report same to the network device, one of the beams is used for downlink transmission, and the other is used for uplink transmission. In this way, when a terminal does not satisfy beam consistency, a backup uplink beam can be found in advance, so that the network device can accurately receive an uplink signal, a case of carrying out uplink beam training again for searching for an uplink beam is avoided, and thus the communication efficiency of uplink beams is improved.
