determining, by the terminal device, according to a RNTI used to scramble the first downlink authorization information and the second downlink authorization information, a PDSCH that is preferentially decoded from the first PDSCH and the second PDSCH. ## Claims ### Claim 1 A downlink channel receiving method, comprising: receiving, by a terminal device, 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 decoding, by the terminal device, 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the decoding, by the terminal device, the first PDSCH and the second PDSCH, comprises: determining, by the terminal device, to preferentially decode the first PDSCH corresponding to the SI-RNTI in case that the terminal device determines that system information is changed; and determining, by the terminal device, to preferentially decode the second PDSCH corresponding to the RA-RNTI or the second PDSCH corresponding to the TC-RNTI in case that the terminal device determines that the system information is unchanged. ### Claim 3 (depends on 1) The method of claim 1, wherein a first symbol in the first time unit is earlier than a first symbol in the second time unit in the time domain, the decoding, by the terminal device, the first PDSCH and the second PDSCH, comprises: determining, by the terminal device, to preferentially decode the first PDSCH. ### Claim 4 (depends on 1) The method of claim 1, wherein a first symbol in the first time unit is earlier than a first symbol in the second time unit in the time domain, the decoding, by the terminal device, the first PDSCH and the second PDSCH, comprises: determining, by the terminal device, to preferentially decode the second PDSCH. ### Claim 5 (depends on 1) A storage medium having a computer program stored thereon, wherein the computer program, when executed by a computing device, causes the storage medium to implement the method of claim 1. ### Claim 6 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. ### Claim 7 (depends on 6) The terminal device of claim 6, wherein the processor is configured to: determine to preferentially decode the first PDSCH corresponding to the SI-RNTI in case that the system information is determined to be changed; and determine to preferentially decode the second PDSCH corresponding to the RA-RNTI or the second PDSCH corresponding to the TC-RNTI in case that the system information is determined to be unchanged. ### Claim 8 (depends on 6) The terminal device of claim 6, wherein a first symbol in the first time unit is earlier than a first symbol in the second time unit in the time domain, the processor is configured to: determine to preferentially decode the first PDSCH. ### Claim 9 (depends on 6) The terminal device of claim 6, wherein a first symbol in the first time unit is earlier than a first symbol in the second time unit in the time domain, the processor is configured to: determine to preferentially decode the second PDSCH. ### Claim 10 (depends on 6) The terminal device of claim 6, wherein the processor is configured to: determine to preferentially decode the first PDSCH and the second PDSCH by itself.
