Method and device for indicating resource allocation
Embodiments of the disclosure provide a method and device for indicating time domain resource allocation. The method comprises: determining time information of a resource region based on numerology information of the resource region, the resource region being allocated for transmitting data to a terminal device; and transmitting the time information to the terminal device to enable the terminal device to receive the data on the resource region.
1. A method performed by a network device, the method comprising:
transmitting, to a terminal device, first time domain resource allocation information for a data transmission, the first time domain resource allocation information indicating a first starting symbol of a resource for the data transmission and a first number of symbols in the resource;
transmitting, to the terminal device, second time domain resource allocation information for the data transmission, the second time domain resource allocation information indicating a second starting symbol of the resource for the data transmission and a second number of symbols in the resource; and
transmitting, to the terminal device, the data transmission based on the first time domain resource allocation information and the second time domain resource allocation information.
2. The method of claim 1 further comprising transmitting, to the terminal device, numerology information at least related with the resource.
3. The method of claim 2 , wherein the numerology information comprises at least one of a subcarrier spacing, a symbol length, and a length of a cyclic prefix.
4. The method of claim 1 , wherein the first time domain resource allocation information indicates a starting symbol of a first resource region of the first resource region and a number of symbols of the first resource region allocated for the data transmission.
5. The method of claim 1 , wherein the first time domain resource allocation information is transmitted via at least one of Downlink Control information or Radio Resource Control (RRC) signaling.
6. The method of claim 1 , wherein the first time domain resource allocation information further comprises a coarse-grain time domain resource indication of the resource and a fine-grain time domain resource indication of the resource.
7. The method of claim 1 , wherein transmitting the first time domain resource allocation information further comprises:
transmitting, to the terminal device, a first portion of the first time domain resource allocation information; and
transmitting, to the terminal device, a second portion of the first time domain resource allocation information.
8. The method of claim 7 , wherein the first portion is transmitted via Radio Resource Control (RRC) signaling.
9. A method performed by a terminal device, the method comprising:
receiving, from a network device, first time domain resource allocation information for a data transmission, the first time domain resource allocation information indicating a first starting symbol of a resource for the data transmission and a first number of symbols in the resource,
receiving, from the network device, second time domain resource allocation information for the data transmission, the second time domain resource allocation information indicating a second starting symbol of the resource for the data transmission and a second number of symbols in the resource; and
receiving, from the network device, the data transmission based on the first time domain resource allocation information and the second time domain resource allocation information.
10. The method of claim 9 , wherein the first time domain resource allocation information indicates a starting symbol of a first resource region of the resource and a number of symbols occupied by the first resource region.
11. The method of claim 9 further comprising receiving, from the network device, numerology information at least related with the resource.
12. The method of claim 11 further comprising determining a time domain resource of the resource based on the first time domain resource allocation information and the numerology information.
13. The method of claim 9 , wherein the first time domain resource allocation information comprises a coarse-grain time domain resource indication of the resource and a fine-grain time domain resource indication of the resource, and a time domain resource of the resource is determined based on the coarse-grain time domain resource indication and the fine-grain time domain resource indication.
14. The method of claim 9 further comprising:
receiving, from the network device, a first portion of the first time domain resource allocation information;
receiving, from the network device, a second portion of the first time domain resource allocation information; and
determining a time domain resource of the resource based on the first portion and the second portion.
15. The method of claim 14 , wherein the first portion is configured via Radio Resource Control (RRC) signaling.
16. A network device comprising:
circuitry configured to control the network device to:
transmit, to a terminal device, first time domain resource allocation information for a data transmission, the first time domain resource allocation information indicating a first starting symbol of a resource for the data transmission and a first number of symbols in the resource;
transmit, to the terminal device, second time domain resource allocation information for the data transmission, the second time domain resource allocation information indicating a second starting symbol of the resource for the data transmission and a second number of symbols in the resource; and
transmit, to the terminal device, the data transmission based on the first time domain resource allocation information and the second time domain resource allocation information.
17. A terminal device comprising:
circuitry configured to control the terminal device to:
receive, from a network device, first time domain resource allocation information for a data transmission, the first time domain resource allocation information indicating a first starting symbol of a resource for the data transmission and a first number of symbols in the resource;
receive, from the network device, second time domain resource allocation information for the data transmission, the second time domain resource allocation information indicating a second starting symbol of the resource for the data transmission and a second number of symbols in the resource; and
receive, from the network device, the data transmission based on the first time domain resource allocation information and the second time domain resource allocation information.
