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

An apparatus for communication in a communication system, comprising:

• a controller;
• and
• a transceiver configured to:
• transmit first information indicating at least two reference signal (RS) resources for at least two RSs, second information for providing quasi co-location relationships between RSs associated with the at least two RS resources and demodulation reference signal (DMRS) ports, and third information indicating a cell index to which a RS resource is applied,
• transmit control information for scheduling of downlink data channel, the control information including information indicating which RS resource from among the at least two RS resources indicated by the first information is quasi co-located with DM-RS ports related to the downlink data channel, and
• transmit a data channel signal scheduled by the control information, based on the first information, the second information, and the third information,
• wherein at least one DMRS port of the downlink data channel is quasi co-located with at least one RS in the RS resource indicated the control information.

A method for communication in a communication system, the method comprising:

• receiving first information indicating at least two reference signal (RS) resources for at least two RSs, second information for providing quasi co-location relationships between RSs associated with the at least two RS resources and demodulation reference signal (DMRS) ports, and third information indicating a cell index to which a RS resource is applied;
• receiving control information for scheduling of downlink data channel, the control information including information indicating which RS resource from among the at least two RS resources indicated by the first information is quasi co-located with DM-RS ports related to the downlink data channel;
• and
• receiving a data channel signal scheduled by the control information, based on the first information, the second information, and the third information,
• wherein at least one DMRS port of the downlink data channel is quasi co-located with at least one RS in the RS resource indicated the control information.
