Method for determining an instance for performing a channel state information measurement and communications apparatuses utilizing the same

摘要

A communications apparatus is provided. A processor is coupled to a transceiver, and at least comprises a first processor logic unit for performing a channel state information measurement at the sub-frame(s) comprised in a first sub-frame subset configured by a peer communications apparatus to obtain a first measurement result, a second processor logic unit for performing a second channel state information measurement at the sub-frame(s) comprised in a second sub-frame subset configured by the peer communications apparatus to obtain a second measurement result, a third processor logic unit for reporting the first measurement result and the second measurement result to the peer communications apparatus via the transceiver at one or more reporting instances. The reporting instances are determined based on a plurality of reporting parameters, and the reporting parameters are respectively configured for the first sub-frame subset and second sub-frame subset by the peer communications apparatus.
