Abstract: Technology for a user equipment (UE) operable to perform channel state information (CSI) measurements in a License Assisted Access (LAA) system is disclosed. The UE can process information received from a base station in the LAA system. The information can be received within a downlink (DL) transmission burst from the base station. The information can indicate one of: a cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS) transmission power offset value for the DL transmission burst, one or more subframes in the DL transmission burst for which the UE is to perform CSI measurements, or a subframe boundary of the DL transmission burst. The UE can perform a CSI measurement for the DL transmission burst based on the information received from the base station. Subframes of the DL transmission burst can be associated with a substantially similar transmission power.
