Abstract:
A scheduling entity can configure semi-persistent scheduling (SPS) resources for downlink data and selectively receiving channel measurements and interference measurements from a user equipment. The scheduling entity can trigger the channel measurements and interference measurements using various methods including SPS configuration activation/reactivation/deactivation, DMRS based triggering, and DCI based triggering. The scheduling entity can benefit from more frequent and/or aperiodic interference and/or channel measurements in performing channel precoding, selecting a modulation and coding scheme (MCS), and estimating/predicting interference, noise, and channel quality at the UE. SPS configured channel and interference measurements also benefit the UE in data decoding that can result in a lower error ratio and higher data rate.
