[0041] As shown in Figure 2 The embodiments of the present application provide a method for determining a beam application time, including:
[0042] Step 201: The terminal receives beam indication signaling, and the beam indication signaling is used to indicate common beam information.
[0043] In this step, the beam indication signaling is used to indicate common beam information of N component carriers (CCs), and the common beam information is used to determine beam information of all or part of channels or reference signals of the CCs, for example, to determine beam information of UE-dedicated reception on PDSCH, UE-specific CORESET, non-UE-specific CORESET, PUCCH or PUSCH, etc., where N is greater than or equal to 1.
[0044] The common beam information can be a joint TCI state or a separate TCI state. The joint TCI state is that the uplink and the downlink share the same TCI state, that is, share the same beam information, and the separate TCI state is that the uplink and the downlink respectively use their own TCI states, that is, respectively use their own beam information.
[0045] It should be noted that the beam information in the embodiments of the present application can also be referred to as: identification information of the beam, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, TCI state information, QCL information or QCL parameters, etc. Among them, the downlink beam information can usually be represented by TCI state information or QCL information. The uplink beam information can usually be represented by TCI state information or spatial relation information.
[0046] Step 202: The terminal determines a target subcarrier spacing according to a subcarrier spacing determination rule, and the target subcarrier spacing includes a first target subcarrier spacing corresponding to N component carriers (CCs) or a second target subcarrier spacing corresponding to a first bandwidth part (BWP) of the N CCs, where N is greater than or equal to 1, and the first BWP is a BWP to which the common beam information is applied, and the first BWP includes at least one of an uplink BWP and a downlink BWP.

[0048] Specifically, the first beam application time is determined according to the first target subcarrier spacing, or the second beam application time is determined according to the second target subcarrier spacing.
