Abstract

This disclosure provides a transmission method, a terminal device, and a network-side device. The method is applied to a terminal device and includes: receiving first indication information from a network-side device, where the first indication information is used to indicate a first resource usable for configured grant transmission within a configured grant resource period; and transmitting first to-be-transmitted data on the first resource for consecutively K times, where K is a positive integer.

First claim

What is claimed is:

1. A transmission method, applied to a terminal device and comprising:
receiving first indication information from a network-side device, wherein the first indication information is used to indicate a first resource usable for configured grant transmission within a configured grant resource period; and
transmitting first to-be-transmitted data on the first resource for consecutively K times, wherein K is a positive integer;
wherein the first resource is determined based on a slot offset and a quantity of consecutive slots, both the slot offset and the quantity of consecutive slots being indicated by the first indication information.

2. The method according to claim 1 , wherein the first indication information indicates the first resource in a field indication.

3. The method according to claim 2 , wherein in a case that the first indication information indicates the first resource in a field indication mode, the first resource is:
one resource; or
M consecutive resources, wherein M is an integer greater than 1; or
S resource groups, wherein each resource group comprises K consecutive resources, and S is a positive integer.

4. The method according to claim 1 , wherein the transmitting first to-be-transmitted data on the first resource for consecutively K times comprises:
if the terminal device succeeds in listen before talk (LBT) after a first time position and before a second time position, or the terminal device succeeds in LBT at a second time position, transmitting the first to-be-transmitted data for consecutively K times starting at the second time position; wherein
the first time position and the second time position are two adjacent time positions in target time positions; and the target time positions are time positions that are determined based on the first resource and that are usable for starting transmitting the to-be-transmitted data for consecutively K times.

5. The method according to claim 4 , wherein in a case that the first resource is M consecutive resources, the target time positions comprise: a start time position of each resource;
wherein after the transmitting the first to-be-transmitted data for consecutively K times starting at the second time position, the method further comprises:
transmitting the second to-be-transmitted data for consecutively K times starting at a third time position in a case that the Kth transmission of the first to-be-transmitted data is completed and there is a remaining resource in the first resource, wherein
the third time position is an end time position of the Kth transmission of the first to-be-transmitted data.

6. The method according to claim 4 , wherein in a case that the first resource is S resource groups, the target time positions comprise: a start time position of each resource group;
wherein after the transmitting the first to-be-transmitted data for consecutively K times starting at the second time position, the method further comprises:
transmitting second to-be-transmitted data for consecutively K times starting at a target time position next to the second time position in a case that the Kth transmission of the first to-be-transmitted data is completed and there is a remaining resource group in the first resource.

7. The method according to claim 4 , wherein in a case that the first resource is Q resource groups, the target time positions comprise: a start time position of each resource group;
wherein after the transmitting the first to-be-transmitted data for consecutively K times starting at the second time position in a case that the Kth transmission of the first to-be-transmitted data is completed and there is a remaining resource group in the first resource, the method further comprises:
if resources in the first resource group and resources in the second resource group are consecutive in the bitmap, transmitting the second to-be-transmitted resource for consecutively K times starting at a target time position next to the second time position; or
if resources in the first resource group and resources in the second resource group are non-consecutive in the bitmap, performing LBT again; and if LBT succeeds after a fourth time position and before a fifth time position, or LBT succeeds at a fifth time position, transmitting the second to-be-transmitted data for consecutively K times starting at the fifth time position, wherein
the first resource group is a resource group comprising the second time position; the second resource group is a resource group next to the first resource group; and the fourth time position and the fifth time position are two adjacent time positions in the target time positions.

8. The method according to claim 4 , wherein in a case that the first resource is T resource groups, the target time positions comprise: a start time position of each resource;
wherein after the transmitting first to-be-transmitted data for consecutively K times starting at the second time position in a case that the Kth transmission of the first to-be-transmitted data is completed and there is a remaining resource group in the first resource, the method further comprises:
if a second resource and a third resource are consecutive in the bitmap, transmitting second to-be-transmitted data for consecutively K times at a start time position of the third resource; or
if a second resource and a third resource are non-consecutive in the bitmap, performing LBT again; and if LBT succeeds after a sixth time position and before a seventh time position, or LBT succeeds at a seventh time position, transmitting second to-be-transmitted data for consecutively K times starting at the seventh time position, wherein
the second resource is a resource comprising an end time position of the Kth transmission of the first to-be-transmitted data; the third resource is a next resource group of the second resource group; and the sixth time position and the seventh time position are two adjacent time positions in the target time positions.

9. The method according to claim 1 , wherein redundancy version (RV) fields corresponding to to-be-transmitted data in all transmissions are all set to be invalid and a same value, wherein
the RV field is carried in uplink control information (UCI).

10. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the transmission method according to claim 1 are implemented.

11. A transmission method, applied to a network-side device and comprising:
transmitting first indication information to a terminal device, wherein the first indication information is used to indicate a first resource usable for configured grant transmission within a configured grant resource period;
wherein the first resource is determined based on a slot offset and a quantity of consecutive slots, both the slot offset and the quantity of consecutive slots being indicated by the first indication information.

12. The method according to claim 11 , wherein the first indication information indicates the first resource in a field indication mode.

13. The method according to claim 12 , wherein in a case that the first indication information indicates the first resource in a field indication mode, the first resource is:
one resource; or
M consecutive resources, wherein M is an integer greater than 1; or
S resource groups, wherein each resource group comprises K consecutive resources, and S is a positive integer.

14. A network-side device, comprising a processor, a memory, and a computer program stored i
