13. A communication apparatus, comprising:
at least one processor coupled to at least one non-transitory computer-readable storage medium storing programming instructions for execution by the at least one processor, wherein the programming instructions cause the communication apparatus to implement operations comprising:
receiving first indication information from a network device, wherein the first indication information indicates a mapping type of a physical shared channel, wherein the mapping type of the physical shared channel is a first type or a second type, wherein the first type comprises PDSCH mapping type A or PUSCH mapping type A, and the second type comprises PDSCH mapping type B or PUSCH mapping type B; and
determining time domain positions occupied by a demodulation reference signal (DMRS) in a resource unit based on the mapping type of the physical shared channel, wherein, under different mapping types, the time domain positions occupied by the DMRS in the resource unit are determined based on different parameters in a manner comprising:
in response to that the mapping type of the physical shared channel is the first type, the time domain positions occupied by the DMRS in the resource unit are determined based on a position index of a last symbol occupied by the physical shared channel in the resource unit; and
in response to that the mapping type of the physical shared channel is the second type, the time domain positions occupied by the DMRS in the resource unit are determined based on a quantity of symbols occupied by the physical shared channel in the resource unit.
