Method for aggregation transmission of multi-user downlink data and apparatus

A method for aggregation transmission of multi-user downlink data, wherein the method is performed by a first communications apparatus, the first communications apparatus is a first terminal device or a module of the first terminal device, and the method comprises:

• receiving first indication information from a network device, wherein:
• the first indication information indicates location information of first downlink data of the first terminal device in a first downlink bit sequence;
• the first downlink bit sequence comprises downlink data of each of N terminal devices, the first terminal device is one of the N terminal devices;
• and
• N is an integer greater than 1;
• receiving second indication information from the network device, wherein the second indication information comprises information about a first time-frequency resource;
• receiving a second downlink bit sequence on the first time-frequency resource;
• performing channel decoding on the second downlink bit sequence to obtain the first downlink bit sequence;
• and
• obtaining the first downlink data based on the first indication information and the first downlink bit sequence.
