Quasi co-location identification of reference symbol ports for coordinated multi-point communication systems

An apparatus for receiving reference signals by an user equipment (UE), the apparatus comprising:

• a controller;
• and
• receiver processing circuitry configured to:
• receive channel state information reference signal (CSI-RS) configuration information including a CSI-RS configuration identifier (ID), a resource configuration, a subframe configuration, and quasi co-location (QCL) cell-specific reference signal (CRS) information;
• and
• receive a CSI-RS and a CRS corresponding to the CSI-RS configuration information based on the CSI-RS configuration information,
• wherein the QCL CRS information indicates the CRS corresponding to the CSI-RS configuration information that is quasi co-located with the CSI-RS corresponding to the CSI-RS configuration information.

• receive a CSI-RS and a CRS corresponding to the CSI-RS configuration information based on the CSI-RS configuration information,
• receive a control channel including demodulation reference signal (DMRS) information and QCL information, and
• receive a data channel indicated by the control channel, based on at least one DMRS port corresponding to the DMRS information and at least one CSI-RS port corresponding to the QCL information,
• wherein the QCL CRS information indicates the CRS corresponding to the CSI-RS configuration information that is quasi co-located with the CSI-RS corresponding to the CSI-RS configuration information, and
• wherein the at least one DMRS port corresponding to the DMRS information and at least one CSI-RS port corresponding to the QCL information is quasi co-located.
