Abstract

A resource determining method and a device are provided. The method includes: obtaining indication information of one or more reference points of a target resource; and determining the target resource according to the indication information.

First claim

The invention claimed is:

1. A resource determining method, comprising:
obtaining indication information of one or more reference points of a target resource; and
determining the target resource according to the indication information,
wherein the indication information comprises a position of a first channel, the first channel comprises a Physical Downlink Shared CHannel (PDSCH), and the first channel comprises a channel on a cell corresponding to a lowest cell identity in one or more scheduled cells; and/or
wherein the indication information is used to determine a target reference point, wherein:
when the indication information indicates only one reference point, the target reference point is determined to be the one reference point indicated by the indication information; or
when the indication information indicates multiple reference points, the target reference point is determined based on the multiple reference points, wherein the target reference point comprises a reference point at a position at which a second channel is located, wherein the second channel comprises a channel that ends last in one or more scheduled channels.

2. The method according to claim 1 , wherein for a reference point from the one or more reference points, the indication information further comprises at least one of the following:
a type of the reference point;
a time offset of the reference point relative to a first position;
a period of the reference point;
an indication identifier of a frequency domain resource in which the reference point is located;
an indication identifier of a time domain resource in which the reference point is located;
a reference point identifier;
cell information;
BandWidth Part (BWP) information; or
Hybrid Automatic Repeat reQuest (HARQ) process information of the reference point.

3. The method according to claim 2 , wherein the first channel comprises at least one of the following:
a channel on a cell corresponding to a first preset cell identity in the one or more scheduled cells;
a channel on a BWP corresponding to a first preset BWP identifier in scheduled BWPs;
a channel on a BWP corresponding to a first preset SubCarrier Spacing (SCS) in the scheduled BWPs; or
a channel on which a resource corresponding to a second preset SCS in scheduled resources is located.

4. The method according to claim 2 , wherein the first position comprises at least one of the following:
a position of a time domain resource in which the indication information is located;
a position of a time domain resource in which downlink control information is located;
a position of a target slot of a preset System Frame Number (SFN);
a boundary of a target window;
a start position of a period of search space in which the downlink control information is located;
an end position of the period of the search space in which the downlink control information is located;
a time domain position of a reference object; or
a time domain position of a quasi-co-location reference.

5. The method according to claim 2 , wherein the cell information comprises a cell identity or a cell bitmap.

6. The method according to claim 2 , wherein the cell information comprises information about at least one cell or cell group corresponding to the reference point.

7. The method according to claim 2 , wherein the BWP information comprises a BWP identifier or a BWP bitmap.

8. The method according to claim 2 , wherein the BWP information comprises information about at least one BWP or BWP group corresponding to the reference point.

9. The method according to claim 1 , wherein the indication information comprises a reference point bitmap or a reference point number;
at least some bits in the reference point bitmap correspond to at least some reference points in a first reference point set;
the reference point number is a number of a reference point in the first reference point set, or the reference point number is a number of a reference point in a preset quantity of reference points; and
the first reference point set is a set of reference points determined by using at least one of higher layer signaling, pre-defined signaling, or control signaling.

10. The method according to claim 9 , wherein values of the at least some bits comprise at least one of the following:
a first value, used to indicate that a corresponding reference point is used;
a second value, used to indicate that a corresponding reference point is activated; or
a third value, used to indicate that a corresponding reference point is released or not used.

11. The method according to claim 9 , wherein all bits in the reference point bitmap are fourth values used to indicate one of the following:
a reference point indicated by using indication information in a different type from the current indication information;
a user-defined reference point;
no transmission is required;
no feedback is required;
there is no data resource;
there is no feedback resource; or
there is no target resource.

12. The method according to claim 1 ,
wherein the target reference point further comprises at least one of the following:
a reference point at a position at which the indication information is located;
a reference point at a position at which downlink control information is located;
a reference point at a position at which a data channel on a target cell or a target BandWidth Part (BWP) is located;
a reference point that is the farthest from the data channel on the target cell or the target BWP;
a reference point that is the closest to the data channel on the target cell or the target BWP;
a reference point at a position at which downlink control information on the target cell or the target BWP is located;
a reference point that is the farthest from the downlink control information on the target cell or the target BWP;
a reference point that is the closest to the downlink control information on the target cell or the target BWP;
a reference point in a preset reference point type;
a reference point that is the farthest from the downlink control information;
a reference point that is the farthest from the second channel;
a reference point that is the closest to the downlink control information;
a reference point that is the closest to the second channel;
a reference point with which an interval between a feedback resource and a data resource is greater than a processing delay; or
a reference point that meets a first Hybrid Automatic Repeat reQuest (HARQ) number.

13. The method according to claim 12 , wherein the first HARQ number comprises at least one of the following:
a HARQ number corresponding to transmission;
a HARQ number corresponding to the target resource;
a HARQ number indicated or configured by the indication information; or
a HARQ number indicated or configured by the downlink control information.

14. The method according to claim 12 , wherein the second channel further comprises at least one of the following:
a channel that starts or ends first in the one or more scheduled channels;
a channel that starts in the one or more scheduled channels;
a channel with a preset identifier in the one or more scheduled channels;
a channel with a largest SubCarrier Spacing (SCS) in the one or more scheduled channels;
a channel with a smallest SCS in the one or more scheduled channels; or
a channel whose SCS is a third preset SCS in the one or more scheduled channels.

15. The method according to claim 12 , wherein the target cell comprises at least one of the following:
a cell configured with common search space;
a
