Resource mapping method and apparatus, and resource mapping indication method and apparatus

An apparatus, comprising:

• at least one processor coupled to one or more memories storing programming instructions that, when executed by the at least one processor, cause the at least one processor to:
• obtain information indicating a mapping mode used for resource mapping during uplink transmission, wherein the mapping mode is indicative of 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 a 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
• determine 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 resource elements (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.

A method, comprising:

• obtaining, by a network device, a mapping mode used for resource mapping during uplink transmission;
• and
• sending, by the network device to a terminal, information indicating the mapping mode, wherein
• the mapping mode is indicative of mapping locations of a plurality of modulation symbols of a plurality of terminals in a resource mapping block (RMB), the plurality of modulation symbols comprise 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
• 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 resource elements (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.
