Techniques for harmonization between CRS and DMRS based transmission modes in unlicensed spectrum

摘要

Various aspects relating to techniques for harmonization between the common reference signal (CRS) and the demodulation reference signal (DM-RS) based transmission modes (TM) in the unlicensed spectrum are described. In one aspect, a downlink / uplink (DL / UL) subframe configuration may be signaled for each subframe. The information provided by the DL / UL subframe configuration is such that each downlink subframe is either a single-frequency network (MBSFN) subframe (associated with a DL-RS-based TM) or a non- It may indicate whether the frame is a frame or not. In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinuous reception (DRX) wakeups for unauthorized carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in the grant spectrum.
