Abstract

Methods, wireless devices and network nodes for avoiding collision between a downlink control channel and a aperiodic channel state information reference signal, aperiodic CSI-RS, are provided. According to some aspects, a method is provided that includes receiving an aperiodic channel state information reference signal, aperiodic CSI-RS, based on an assumption that the aperiodic CSI-RS is not present in physical layer resources corresponding to a downlink control channel set.
