Channel measurement method and terminal apparatus

A method, comprising:

• receiving, by a second terminal apparatus, reference signal configuration information from a first terminal apparatus, the reference signal configuration information indicating a resource of a first reference signal, the first reference signal being used for channel measurement;
• receiving, by the second terminal apparatus, channel report configuration information from the first terminal apparatus, the channel report configuration information comprising a candidate time interval, the candidate time interval being a time interval between a time domain resource for carrying trigger information and a time domain resource for carrying a channel measurement report, the trigger information triggering channel measurement;
• receiving, by the second terminal apparatus, first trigger information from the first terminal apparatus;
• receiving, by the second terminal apparatus, the first reference signal from the first terminal apparatus;
• obtaining, by the second terminal apparatus, a first channel measurement report based on the first reference signal;
• determining, by the second terminal apparatus, a first time domain resource based on the channel report configuration information;
• and
• sending, by the second terminal apparatus using the first time domain resource, the first channel measurement report to the first terminal apparatus, wherein sending the first channel measurement report comprises:
• sending, by the second terminal apparatus, the first channel measurement report to the first terminal apparatus in a first time range,
• wherein the first time range has a duration that is a first candidate time interval starting from a moment for sending the first trigger information by the first terminal apparatus.

An apparatus, comprising:

• one or more processors;
• and
• a non-transitory memory configured to store program instructions that are executable by the one or more processors, wherein the program instructions include instructions that, when executed by the one or more processors, cause the apparatus to:
• send reference signal configuration information to a second terminal apparatus, the reference signal configuration information indicating a resource of a first reference signal, the first reference signal being used for channel measurement;
• send channel report configuration information to the second terminal apparatus, the channel report configuration information indicating a candidate time interval, the candidate time interval being a time interval between a time domain resource for carrying trigger information and a time domain resource for carrying a channel measurement report, the trigger information triggering channel measurement;
• send first trigger information to the second terminal apparatus;
• send the first reference signal to the second terminal apparatus;
• and
• detect a channel measurement report from the second terminal apparatus based on the candidate time interval, wherein to detect the channel measurement report, the instructions, when executed by the one or more processors, cause the apparatus to:
• receive a first channel measurement report from the second terminal apparatus in a first time range,
• wherein the first time range has a duration that is a first candidate time interval starting from a moment for sending the first trigger information.
