Communication schemes for small cyclic delay diversity reference signals

Abstract:

The described techniques relate to improved methods, systems, devices, or apparatuses that support communication schemes for small cyclic delay diversity (SCDD) reference signals. A base station may transmit a control message comprising at least one channel state information (CSI) configuration parameter to a user equipment (UE). The UE may identify a time offset between a plurality of virtual antennas of the base station based at least in part on the CSI configuration parameter. The UE may perform measurements of a plurality of CSI reference signals (CSI-RSs) transmitted by the base station and associated with the virtual antennas. The UE may transmit a feedback message based at least in part on the determined time offset and the measurements of the CSI-RSs.
