1. A beam indication method, comprising:
receiving first information from a network device, wherein the first information is used to determine both a first receive beam for a downlink signal and a first transmit beam for an uplink signal, wherein the first information comprises third reference signal configuration information and fourth reference signal configuration information, wherein the third reference signal configuration information indicates an identifier of a third downlink reference signal, and wherein the fourth reference signal configuration information indicates an identifier of a first uplink reference signal; and
determining the first receive beam for the downlink signal and the first transmit beam for the uplink signal based on the first information, wherein the determining the first receive beam and the first transmit beam based on the first information comprises performing at least one of:
determining the third downlink reference signal based on the third reference signal configuration information, and determining the first receive beam based on the third downlink reference signal; or
determining the first uplink reference signal based on the fourth reference signal configuration information, and determining the first transmit beam based on the first uplink reference signal.
