Method for determining resource location, terminal device, and non-transitory computer readable storage medium
View Patent ↗Embodiments of the application provide a method for determining a resource location in a terminal device, a terminal device, and a non-transitory computer readable storage medium. A terminal device determines a second downlink slot corresponding to the CSI reporting moment based on a first uplink slot where channel state information (CSI) reporting moment is located; the terminal device obtains a slot offset, where the slot offset is a slot offset of a location of a CSI reference resource on a time domain relative to the second uplink slot; the terminal device determines the location of the CSI reference resource on the time domain based on the second uplink slot and the slot offset.
1. A method for determining a resource location, implemented by a terminal device, the method comprising:
determining, based on a first uplink slot where channel state information (CSI) reporting moment is located, a second downlink slot corresponding to the CSI reporting moment;
obtaining a slot offset, wherein the slot offset is a slot offset of a location of a CSI reference resource on a time domain relative to the second downlink slot; and
determining a third downlink slot as the location of the CSI reference resource on the time domain, wherein the third downlink slot is obtained by subtracting the slot offset from the second downlink slot,
wherein the second downlink slot is determined according to the following formula:
n

where n′ represents the second downlink slot, n represents the first uplink slot, μ 1 represents subcarrier spacing configuration for downlink, and μ 2 represents subcarrier spacing configuration for uplink.
2. The method of claim 1 , wherein obtaining the slot offset comprises:
determining the slot offset based on downlink measurement resource configuration comprised in CSI reporting configuration information.
3. The method of claim 2 , wherein determining the slot offset based on the downlink measurement resource configuration comprised in the CSI reporting configuration information comprises:
determining the slot offset based on a subcarrier spacing corresponding to the downlink measurement resource configuration comprised in the CSI reporting configuration information.

the downlink measurement resource configuration comprised in the CSI reporting configuration information comprises: configuration of a measurement resource corresponding to CSI reporting.
5. The method of claim 2 , wherein
the CSI reporting configuration information further comprises: CSI reporting being periodic reporting, or quasi-periodic reporting.
6. The method of claim 2 , wherein the method further comprises:
receiving first information; and
acquiring the CSI reporting configuration information based on the first information.
7. A terminal device in a communication system, comprising:
a processor; and
a memory storing program instructions,

obtain a slot offset, wherein the slot offset is a slot offset of a location of a CSI reference resource on a time domain relative to the second downlink slot; and
determine a third downlink slot as the location of the CSI reference resource on the time domain, wherein the third downlink slot is obtained by subtracting the slot offset from the second downlink slot,
wherein the second downlink slot is determined according to the following formula:
n
′
=
⌊

where n′ represents the second downlink slot, n represents the first uplink slot, μ 1 represents subcarrier spacing configuration for downlink, and μ 2 represents subcarrier spacing configuration for uplink.
8. The terminal device of claim 7 , wherein, when the program instructions are executed by the processor, the terminal device is further configured to:
determine the slot offset based on downlink measurement resource configuration comprised in CSI reporting configuration information.
9. The terminal device of claim 8 , wherein, when the program instructions are executed by the processor, the terminal device is further configured to:
determine the slot offset based on a subcarrier spacing corresponding to the downlink measurement resource configuration comprised in the CSI reporting configuration information.
10. The terminal device of claim 8 , wherein
the downlink measurement resource configuration comprised in the CSI reporting configuration information comprises: configuration of a measurement resource corresponding to CSI reporting.
11. The terminal device of claim 8 , wherein
the CSI reporting configuration information further comprises: CSI reporting being periodic reporting, or quasi-periodic reporting.
12. The terminal device of claim 8 , wherein, when the program instructions are executed by the processor, the terminal device is further configured to:
receive, through a transceiver, first information; and
acquire the CSI reporting configuration information based on the first information.
13. A non-transitory computer readable storage medium, storing computer readable instructions, which when executed by a processor, cause the processor to perform operations comprising:
determining, based on a first uplink slot where channel state information (CSI) reporting moment is located, a second downlink slot corresponding to the CSI reporting moment;
obtaining a slot offset, wherein the slot offset is a slot offset of a location of a CSI reference resource on a time domain relative to the second downlink slot; and
determining a third downlink slot as the location of the CSI reference resource on the time domain, wherein the third downlink slot is obtained by subtracting the slot offset from the second downlink slot,
wherein the second downlink slot is determined according to the following formula:
n
