1. A beam determination method, performed by a user equipment (UE), comprising:
determining, by the UE, whether a common beam state is a valid state; and
determining, by the UE, that at least two channels and/or reference signals of different types of the UE use the same beam for transmission, in case that the common beam state is the valid state;
wherein the determining, by the UE, whether a common beam state is a valid state, includes at least one of the following:
determining, by the UE, whether the common beam state is the valid state according to received common beam state indication information;
determining, by the UE, whether the common beam state is the valid state according to preconfigured time during which the common beam state is the valid state; or,
determining, by the UE, whether the common beam state is the valid state according to a preset event on the UE or a network device; wherein the preset event includes at least one of UE beam sweeping, UE beam reporting, UE beam failure, base station beam sweeping, or base station beam indication.
