Abstract

This application relates to the mobile communications field, and in particular, to an air interface resource scheduling and allocation technology in the wireless communications field. In a resource scheduling and allocation method, a network device allocates, by using a downlink control information, an air interface resource used for N data transmissions to same user equipment, the downlink control information includes information about the air interface resource used for the N data transmissions, and N is an integer greater than 1.

Claims (49)

1. A resource scheduling and allocation method, wherein the method comprises:

obtaining, by a mobile device, an air interface resource that is used for N data transmissions and that is allocated to the mobile device by a network device using a downlink control information, wherein the downlink control information comprises:

information about the air interface resource used for the N data transmissions; and

information about a value of N, N being an integer greater than 1, the value of N being in accordance with a maximum quantity of transmissions of to-be-transmitted data that can be completed within a permissible transmission latency time range for a service associated with the to-be-transmitted data, the N data transmissions corresponding to the to-be-transmitted data; and

transmitting or receiving, by the mobile device, at least a portion of the N data transmissions on the air interface resource configured in the downlink control information.

2. The method according to claim 1 , wherein the downlink control information further comprises continuous transmission indication information.

3. The method according to claim 1 , wherein the information about the air interface resource further comprises a time domain resource indication of the air interface resource and/or redundancy version (RV) information used for a data transmission.

4. The method according to claim 1 , wherein that the downlink control information comprises information about the air interface resource used for the N data transmissions comprises:

the downlink control information comprises information about an air interface resource used for a first data transmission corresponding to the downlink control information, and an air interface resource used for a remaining data transmission corresponding to the downlink control information is determined based on the information about the air interface resource used for the first data transmission; or

the downlink control information comprises information about an air interface resource used for each data transmission corresponding to the downlink control information.

5. The method according to claim 1 , wherein the N data transmissions comprise:

at least one retransmission using a hybrid automatic repeat request (HARQ) mechanism; and

at least one retransmission using a blind retransmission mechanism.

6. A network device, comprising:

at least one processor configured to:

determine, based on a permissible transmission latency time range for a service associated with to-be-transmitted data, a maximum quantity of transmissions of the to-be-transmitted data that can be completed within the permissible transmission latency time range;

allocate, using a downlink control information, an air interface resource used for N data transmissions to a same mobile device, wherein the downlink control information comprises:

information about the air interface resource used for the N data transmissions; and

information about a value of N, N being an integer greater than 1, the value of N being in accordance with the maximum quantity of transmissions of the to-be-transmitted data, the N data transmissions corresponding to the to-be-transmitted data; and

at least one transmitter configured to transmit the downlink control information.

7. The network device according to claim 6 , wherein:

the network device further comprises a receiver, configured to receive the N data transmissions on the air interface resource configured in the downlink control information; or

the at least one transmitter is further configured to transmit the N data transmissions on the air interface resource configured in the downlink control information.

8. The network device according to claim 6 , wherein the downlink control information further comprises continuous transmission indication information.

9. The network device according to claim 6 , wherein the information about the air interface resource comprises a frequency domain resource indication of the air interface resource.

10. The network device according to claim 6 , wherein the information about the air interface resource further comprises a time domain resource indication of the air interface resource and/or redundancy version (RV) information used for a data transmission.

11. The network device according to claim 6 , wherein that the downlink control information comprises information about the air interface resource used for N data transmissions comprises:

the downlink control information comprises information about an air interface resource used for a first data transmission corresponding to the downlink control information, and an air interface resource used for a remaining data transmission corresponding to the downlink control information is determined based on the information about the air interface resource used for the first data transmission; or

the downlink control information comprises information about an air interface resource used for each data transmission corresponding to the downlink control information.

12. The network device according to claim 6 , wherein:

at least one of the N data transmissions is a retransmission; and

determining the maximum quantity of transmissions of the to-be-transmitted data that can be completed within the permissible transmission latency time range is further based on two or more retransmission mechanism options.

13. A mobile device, comprising:

at least one receiver configured to receive downlink control information transmitted by a network device; and

at least one processor configured to obtain an air interface resource that is used for N data transmissions and that is allocated to the mobile device by the network device using the downlink control information, wherein the downlink control information comprises:

information about the air interface resource used for the N data transmissions; and

information about a value of N, N being an integer greater than 1, the value of N being in accordance with a maximum quantity of transmissions of to-be-transmitted data that can be completed within a permissible transmission latency time range for a service associated with the to-be-transmitted data, the N data transmissions corresponding to the to-be-transmitted data.

14. The mobile device according to claim 13 , wherein:

the mobile device further comprises a transmitter, configured to transmit the N data transmissions on the air interface resource configured in the downlink control information; or

the at least one receiver is further configured to receive the N data transmissions on the air interface resource configured in the downlink control information.

15. The mobile device according to claim 13 , wherein the downlink control information further comprises continuous transmission indication information.

16. The mobile device according to claim 13 , wherein the information about the air interface resource comprises a frequency domain resource indication of the air interface resource.

17. The mobile device according to claim 13 , wherein the information about the air interface resource further comprises a time domain resource indication of the air interface resource and/or redundancy version (RV) information used for a data transmission.

18. The mobile device according to claim 13 , wherein that the downlink control information comprises information about the air interface resource used for the N data transmissions comprises:

the downlink control information comprises information about an air interface resource used for a first data transmission corresponding to the downlink control information, and an air interface resource used for a remaining data transmission corresponding to the downlink control information is determined based on the information about the air interface resource used for the first data transmission; or

the downlink control information comprises information about an air interface resource used for each data transmission corresponding to the downlink control information.

19. The mobile device according to claim 13 , wherein the N data transmissions comprise:
