Downlink channel receiving method and terminal device

A terminal device, comprising:

• a transceiver, a memory, a processor, and a computer program stored on the memory and operable on the processor,
• wherein in case that the processor runs the computer program, the processor is configured to:
• control the transceiver to receive first downlink authorization information and second downlink authorization information that are sent by a network device, wherein the first downlink authorization information is used to indicate that the terminal device receives a first physical downlink shared channel (PDSCH) in a first time unit, the second downlink authorization information is used to indicate that the terminal device receives a second PDSCH in a second time unit, and at least one symbol of the first time unit and at least one symbol of the second time unit overlap in a time domain;
• and
• decode, according to a radio network temporary identifier (RNTI) used to scramble the first downlink authorization information and the second downlink authorization information, the first PDSCH and the second PDSCH,
• wherein the first downlink authorization information is downlink authorization information scrambled with a system information-radio network temporary identifier (SI-RNTI) and the second downlink authorization information is downlink authorization information scrambled with a random access-radio network temporary identifier (RA-RNTI) or a temporary cell-radio network temporary identifier (TC-RNTI);
• and
• wherein the terminal device is a terminal device in an idle state.
