Abstract

Claims (27)

1. An apparatus comprising:

at least one processor coupled to a non-transitory memory having a computer program stored thereon, wherein the at least one processor is configured to execute instructions of the computer program, and execution of the instructions enables the apparatus to:

receive, via a control channel, downlink control information (DCI) with a cyclic redundancy code (CRC) scrambled by a first radio network temporary identifier (RNTI) of a plurality of RNTIs, a value of the first RNTI indicating a first time domain resource set, and the first time domain resource set comprising a first time domain resource, wherein the plurality of RNTIs further comprises a second RNTI whose value indicates a second time domain resource set, and the second RNTI is different from the first RNTI, and wherein the first time domain resource set is predefined in a protocol or configured by radio resource control (RRC) signaling, the second time domain resource set is predefined in the protocol or configured by radio resource control (RRC) signaling, and the DCI comprises first information corresponding to a value of an index of the first time domain resource in the first time domain resource set, different time domain resources in the first time domain resource set corresponding to different indexes;

determine the first time domain resource set based on the value of the first RNTI;

determine the first time domain resource based on the first time domain resource set and the first information; and

perform, via a data channel, information transmission on the first time domain resource; and

wherein the first time domain resource set and the second time domain resource set are predefined in a protocol, the second time domain resource set is different from the first time domain resource set.

2. The apparatus according to claim 1 , wherein a location of a start symbol of the first time domain resource is an absolute location in a slot or a location in the slot that is relative to a physical downlink control channel (PDCCH) carrying the DCI.

3. The apparatus according to claim 2 , wherein whether the location of the start symbol of the first time domain resource is the absolute location in the slot or the location relative to the PDCCH is predefined in a system or the protocol, or is notified by signaling.

4. The apparatus according to claim 1 , wherein the first information further indicates a quantity of slots for multi-slot scheduling.

5. A method comprising:

receiving, via a control channel, downlink control information (DCI) with a cyclic redundancy code (CRC) scrambled by a first radio network temporary identifier (RNTI) of a plurality of RNTIs, a value of the first RNTI indicating a first time domain resource set, and the first time domain resource set comprising a first time domain resource, wherein the plurality of RNTIs further comprises a second RNTI whose value indicates a second time domain resource set, and the second RNTI is different from the first RNTI, and wherein the first time domain resource set is predefined in a protocol or configured by radio resource control (RRC) signaling, the second time domain resource set is predefined in the protocol or configured by RRC signaling, and the DCI comprises first information corresponding to a value of an index of the first time domain resource in the first time domain resource set, different time domain resources in the first time domain resource set corresponding to different indexes;

determining the first time domain resource set based on the value of the first RNTI;

determining the first time domain resource based on the first time domain resource set and the first information; and

performing, via a data channel, information transmission on the first time domain resource; and

wherein the first time domain resource set and the second time domain resource set are predefined in a protocol, the second time domain resource set is different from the first time domain resource set.

6. The method according to claim 5 , wherein a location of a start symbol of the first time domain resource is an absolute location in a slot or a location in the slot that is relative to a physical downlink control channel (PDCCH) carrying the DCI.

7. The method according to claim 6 , wherein whether the location of the start symbol of the first time domain resource is the absolute location in the slot or the location relative to the PDCCH is predefined in a system or the protocol, or is notified by signaling.

8. The method according to claim 5 , wherein the first information further indicates a quantity of slots for multi-slot scheduling.

9. An apparatus comprising:

at least one processor coupled to a non-transitory memory having a computer program stored thereon, wherein the at least one processor is configured to execute instructions of the computer program, execution of the instructions enables the apparatus to:

determine a first time domain resource set based on a value of a first radio network temporary identifier (RNTI);

send, via a control channel, downlink control information (DCI) with a cyclic redundancy code (CRC) scrambled by the first RNTI of a plurality of RNTIs, wherein the value of the first RNTI indicates the first time domain resource set, and the first time domain resource set comprises a first time domain resource, wherein the plurality of RNTIs further comprises a second RNTI whose value indicates a second time domain resource set, and the second RNTI is different from the first RNTI, and wherein the first time domain resource set is predefined in a protocol or configured by radio resource control (RRC) signaling, the second time domain resource set is predefined in the protocol or configured by radio resource control (RRC) signaling, and the DCI comprises first information corresponding to a value of an index of the first time domain resource in the first time domain resource set, different time domain resources in the first time domain resource set corresponding to different indexes; and

performing, via a data channel, information transmission on the first time domain resource; and

wherein the first time domain resource set and the second time domain resource set are predefined in a protocol, the second time domain resource set is different from the first time domain resource set.

10. The apparatus according to claim 9 , wherein a location of a start symbol of the first time domain resource is an absolute location in a slot or a location in the slot that is relative to a physical downlink control channel (PDCCH) carrying the DCI.

11. The apparatus according to claim 10 , wherein whether the location of the start symbol of the first time domain resource is the absolute location in the slot or the location relative to the PDCCH is predefined in a system or a protocol, or is notified to a terminal via signaling.
