Abstract
Embodiments of the present application provide a method for measuring a channel busy ratio (CBR), a terminal device, and a network device, which are applicable to calculating the CBR in a sidelink transmission system configured with SL DRX or partial sensing. The method for measuring a CBR includes: a terminal device determines the CBR of a target time according to a measurement result of an SL RSSI within N time units before the target time.

A method for measuring a Channel Busy Ratio (CBR), comprising:
- determining, by a User Equipment (UE), a CBR at a target time according to a measurement result for Sidelink Received Signal Strength Indicator (SL RSSI) within N time units before the target time,
- wherein the N time units comprise part or all of candidate time units in at least one period within a resource sensing window, and the N time units do not comprise non-candidate time units within the resource sensing window,
- wherein a number and a time domain position of the candidate time units in the at least one period are determined according to a number and a time domain position of candidate time units selected by the UE in a resource selection window.
A method for measuring a Channel Busy Ratio (CBR), comprising:
- sending, by a network device, first information to a User Equipment (UE), wherein the first information is configured to indicate N time units before a target time, and a measurement result for Sidelink Received Signal Strength Indicator (SL RSSI) within the N time units is used to determine a CBR at the target time,
- wherein the N time units comprise part or all of candidate time units in at least one period within a resource sensing window, and the N time units do not comprise non-candidate time units within the resource sensing window,
- wherein a number and a time domain position of the candidate time units in the at least one period are determined according to a number and a time domain position of candidate time units selected by the UE in a resource selection window.
A User Equipment (UE), comprising a processor and a memory,
- wherein the processor is configured to invoke and run computer program stored in the memory to implement following operation:
- determining a Channel Busy Ratio (CBR) at a target time according to a measurement result for Sidelink Received Signal Strength Indicator (SL RSSI) within N time units before the target time,
- wherein the N time units comprise part or all of candidate time units in at least one period within a resource sensing window, and the N time units do not comprise non-candidate time units within the resource sensing window,
- wherein a number and a time domain position of the candidate time units in the at least one period are determined according to a number and a time domain position of candidate time units selected by the UE in a resource selection window.
A network device, comprising a processor and a memory,
- wherein the processor is configured to invoke and run computer program stored in the memory to implement following operation:
- sending first information to a User Equipment (UE), wherein the first information is configured to indicate N time units before a target time, and a measurement result for Sidelink Received Signal Strength Indicator (SL RSSI) within the N time units is used to determine a CBR at the target time,
- wherein the N time units comprise part or all of candidate time units in at least one period within a resource sensing window, and the N time units do not comprise non-candidate time units within the resource sensing window,
- wherein a number and a time domain position of the candidate time units in the at least one period are determined according to a number and a time domain position of candidate time units selected by the UE in a resource selection window.
