Method for scheduling terminal device, and network device

A network device, comprising:

• a processor, a memory, a bus system, and a transceiver, wherein the processor, the memory, and the transceiver are connected by using the bus system, the transceiver is configured to receive data sent by a terminal device, and the memory is configured to store instructions that, when executed by the processor, cause the network device to:
• perform blind detection on each of N subframes according to at least one codebook and a pilot corresponding to each of the at least one codebook and by using the data received by the transceiver, wherein N is a positive integer;
• determine, according to a blind detection result, a first pilot set corresponding to each codebook in each subframe, wherein correct terminal data cannot be obtained by performing blind detection by using a pilot in the first pilot set and a corresponding codebook;
• determine, according to the first pilot set corresponding to each codebook in each subframe, a second pilot set corresponding to each codebook in each subframe, wherein a pilot in the second pilot set is a pilot that is in the first pilot set and that has already been sent by the terminal device;
• and
• determine a to-be-used transmission mode of the terminal device according to the second pilot set corresponding to each codebook in each subframe, wherein different transmission modes correspond to different spectrum multiplex rates.
