techniques for harmonization between crs and dm-rs based on unlicensed spectrum transmission modes

摘要

Several aspects related to techniques for harmonization between common reference signal (crs) and demodulation reference signal (dm-rs) (tms) based transmission modes in 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 may indicate whether the respective downlink subframe is a single frequency network (mbsfn) subframe (associated with dm-rs-based tm) or a subframe non-mbsfn (associated with crs-based tm) in another aspect, periodic as well as aperiodic channel state reporting (csi) requests may be supported. In yet another aspect, the interrupted reception (drx) waking for unlicensed carriers may be explicitly or implicitly indicated for a user equipment (eu) through a bearer in a licensed spectrum.
