1. A method, comprising:
obtaining, by a terminal, information indicating a mapping mode used for resource mapping during uplink transmission, wherein the mapping mode indicates mapping locations of a plurality of modulation symbols of a plurality of terminals in a resource mapping block (RMB), the plurality of modulation symbols comprises to-be-sent modulation symbols of the terminal, the RMB comprises a plurality of resource elements (REs), and at least one of the plurality of REs carries at least two of the plurality of modulation symbols of the plurality of terminals; and
determining, by the terminal based on the mapping mode, mapping locations of the to-be-sent modulation symbols of the terminal in the RMB,
wherein the mapping mode comprises a mapping matrix, and columns in the mapping matrix are in a one-to-one correspondence with the plurality of REs comprised in the RMB, a quantity of the columns in the mapping matrix corresponds to a quantity of the plurality of REs comprised in the RMB, and a quantity of rows in the mapping matrix indicates a maximum quantity of modulation symbols carried on any one of the plurality of REs.
