1. A resource mapping method performed by an apparatus, comprising:
determining data to be sent that is carried on a data channel Physical Downlink Shared Channel, PDSCH/Physical Uplink Shared Channel, PUSCH;
mapping the data to be sent to Virtual Resource Blocks, VRBs; and
mapping VRBs in a bundle j∈{0, 1, . . . , Nbundle−1} to Physical Resource Blocks, PRBs, based on a scheme, wherein the scheme comprises:
directly mapping VRB bundle Nbundle−1 to PRB bundle Nbundle−1 without an interleaver; or
directly mapping VRB bundle i to PRB bundle i without an interleaver, wherein i ∈{Nbundle−K, . . . , Nbundle−1};
and
mapping remaining VRB bundles based on bundle indexes through interleaved mapping to corresponding PRB bundles;
wherein,
Nbundle is a quantity of RB bundles in a BWP, and the Nbundle RB bundles are numbered from 0 to Nbundle−1 in an order of frequency;
K is determined by:
K=Nbundle−└Nbundle/P┘×P, and K≥1;
wherein P is a quantity of rows or columns of an interleaver.
