Abstract

A resource scheduling method, a terminal device, and a network device are provided. The method includes: a terminal device receiving first scheduling information, the first scheduling information being used for scheduling at least two physical channels; and the terminal device determining, according to the first scheduling information, transmission resources for the at least two physical channels.

First claim

The invention claimed is:

1. A method for scheduling resource, applicable for a terminal device, comprising:
receiving, by the terminal device, first scheduling information, wherein the first scheduling information is used for scheduling at least two physical channels; and
determining, by the terminal device, transmission resources of the at least two physical channels according to the first scheduling information, wherein,
the at least two physical channels comprise a first physical channel and a second physical channel,
the first scheduling information comprises third information, and
the third information is used for determining a transmission resource of the first physical channel and a transmission resource of the second physical channel,
wherein determining, by the terminal device, the transmission resources of the at least two physical channels according to the first scheduling information comprises:
determining, by the terminal device, time domain resource ranges of the first physical channel and the second physical channel according to the third information; and
determining, by the terminal device, feedback information transmission resources of the first physical channel and the second physical channel according to the third information.

2. The method of claim 1 , wherein,
the transmission resources comprise at least one of the following: time domain resources, frequency domain resources and feedback information transmission resources.

3. The method of claim 1 , wherein,
the first physical channel corresponds to a first sub-carrier spacing,
the second physical channel corresponds to a second sub-carrier spacing,
determining, by the terminal device, the feedback information transmission resources of the first physical channel and the second physical channel according to the third information comprises:
when the first sub-carrier spacing is different from the second sub-carrier spacing, determining, by the terminal device, the feedback information transmission resources of the first physical channel and the second physical channel according to the third information and a reference sub-carrier spacing; or
when the first sub-carrier spacing is different from the second sub-carrier spacing, determining, by the terminal device, a feedback information transmission resource of the first physical channel according to the third information and the first sub-carrier spacing, and determining, by the terminal device, a feedback information transmission resource of the second physical channel according to the third information and the second sub-carrier spacing; or
when the first sub-carrier spacing is the same as the second sub-carrier spacing, determining, by the terminal device, the feedback information transmission resources of the first physical channel and the second physical channel according to the third information and the reference sub-carrier spacing; or
when the first sub-carrier spacing is the same as the second sub-carrier spacing, determining, by the terminal device, the feedback information transmission resources of the first physical channel and the second physical channel according to the third information and a fourth sub-carrier spacing, wherein the fourth sub-carrier spacing is equal to the first sub-carrier spacing or the second sub-carrier spacing; or
when the first sub-carrier spacing is the same as the second sub-carrier spacing and an end time of the first physical channel is different from an end time of the second physical channel, determining, by the terminal device, the feedback information transmission resources of the first physical channel and the second physical channel based on a later end time.

4. The method of claim 3 , wherein a time domain position of the feedback information transmission resource of the first physical channel determined according to the third information is the same as a time domain position of the feedback information transmission resource of the second physical channel.

5. The method of claim 3 , wherein,
the reference sub-carrier spacing is a smaller one of the first sub-carrier spacing and the second sub-carrier spacing; or,
the reference sub-carrier spacing is a greater one of the first sub-carrier spacing and the second sub-carrier spacing; or,
the reference sub-carrier spacing is predetermined by a protocol; or,
the reference subcarrier spacing is configured by a high layer; or,
the reference subcarrier spacing is determined based on a fourth information in the first scheduling information.

6. The method of claim 1 , wherein,
the third information comprises a first part of information and a second part of information,
the first part of information is used for indicating at least one of the following of the first physical channel: a time domain resource range, a frequency domain resource range, a feedback information transmission resource, and
the second part of information is used for indicating at least one of the following of the second physical channel: a time domain resource range, a frequency domain resource range, a feedback information transmission resource.

7. The method of claim 1 , wherein the first scheduling information comprises downlink control information (DCI).

8. A terminal device comprising a processor and a memory, wherein the memory is configured to store a computer program, the processor is configured to invoke and run the computer program stored in the memory to perform:
receiving first scheduling information, wherein the first scheduling information is used for scheduling at least two physical channels;
determining transmission resources of the at least two physical channels according to the first scheduling information, wherein,
the at least two physical channels comprise a first physical channel and a second physical channel,
the first scheduling information comprises third information, and
the third information is used for determining a transmission resource of the first physical channel and a transmission resource of the second physical channel,
wherein determining the transmission resources of the at least two physical channels according to the first scheduling information comprises:
determining time domain resource ranges of the first physical channel and the second physical channel according to the third information; and
determining feedback information transmission resources of the first physical channel and the second physical channel according to the third information.

9. The terminal device of claim 8 , wherein,
the first physical channel corresponds to a first sub-carrier spacing,
the second physical channel corresponds to a second sub-carrier spacing,
determining the feedback information transmission resources of the first physical channel and the second physical channel according to the third information comprises:
when the first sub-carrier spacing is different from the second sub-carrier spacing, determining the feedback information transmission resources of the first physical channel and the second physical channel according to the third information and a reference sub-carrier spacing; or
when the first sub-carrier spacing is different from the second sub-carrier spacing, determining a feedback information transmission resource of the first physical channel according to the third information and the first sub-carrier spacing, and determining a feedback information transmission resource of the second physical channel according to the third information and the second sub-carrier spacing; or
when the first sub-carrier spacing is the same as the second sub-carrier spacing, determining the feedback information transmission resources of the first physical channel and the second physical channel acc
