[0025] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0026] Currently, a terminal can only support one active BWP within a single carrier, and only consecutive BWP configurations are supported; that is, the frequency domain resources for configuring a BWP must be continuous. The configuration of the frequency domain resource locations of physical channels and physical signals are based on or indicated by referring to the continuous frequency domain resources of the BWP in which they reside. For example, physical channels include: Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), etc., and physical signals include: Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), etc.

[0027] Currently, NR has many discontinuous, small-bandwidth spectra, such as Figure 2 As shown, under the previous spectrum usage method, terminals could only perform carrier aggregation on these carriers, but a Transport Block (TB) could only be transmitted within one carrier. Since the bandwidth of each carrier is very small, it cannot support a large TB capacity (TBsize). For a service packet, the base station can only split it into multiple smaller TBs for transmission, which requires multiple PDCCHs to schedule these smaller TBs separately. On the other hand, since the bandwidth of each carrier is very small, it also cannot support PDCCHs with larger aggregation levels.

[0028] In addition, in flexible duplex scenarios, such as Figure 3 As shown, uplink (UL) frequency domain resources can be added in the middle of the downlink (DL) frequency domain resources of the time division duplex (TDD) band to improve the uplink throughput of the TDD band and reduce uplink latency.

[0029] If the current design allows the terminal to support only BWPs with consecutive frequency domain resources, then more than two BWPs must be configured for the terminal. However, the terminal can only work on one BWP at a time, which will prevent the terminal from fully utilizing frequency domain resources and cause a decrease in throughput.

[0030] Therefore, the following technical solutions are proposed according to embodiments of this application. The technical solution of this application proposes a frequency domain resource configuration method to configure a frequency domain resource that is discontinuous in the frequency domain (i.e., a non-continuous resource BWP). As one application scenario, for a full-duplex scenario, a non-continuous downlink BWP is configured for the terminal. As another application scenario, for a small spectrum aggregation scenario, dispersed spectrum resources can be configured into a single BWP.
