1. A method executed by a user equipment for wireless communication, the method comprising:
receiving downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH) transmission;
determining, based on a frequency domain resource assignment (FDRA) field in the received DCI, a resource indication value (RIV);
if a frequency domain resource assignment scaling condition is not satisfied, determining, based on the RIV, a first starting resource block index and a first length of continuous resource blocks;
if the frequency domain resource assignment scaling condition is satisfied, determining, based on the RIV, a second starting resource block index and a second length of continuous resource blocks, wherein the first starting resource block index is determined by multiplying the second starting resource block index by a scaling factor, and the first length of continuous resource blocks is determined by multiplying the second length of continuous resource blocks by the scaling factor; and
determining an allocated frequency resource based on the first starting resource block index and the first length of continuous resource blocks,
wherein:
the scaling factor is determined based on a ratio of a size of an active downlink bandwidth part (BWP) to a size of an initial downlink BWP,
the frequency domain resource assignment scaling condition comprises a size of a format of the DCI that is derived from a first reference size, and
the first reference size is defined based on any one of the following:
a size of a DCI format 1_0 monitored in a common search space (CSS);
a size of a DCI format 0_0 monitored in the CSS; and
a common size of the DCI format 1_0 and a common size of the DCI format 0_0 monitored in the CSS.
