Reference signal port discovery involving transmission points

An apparatus, comprising:

• one or more processors;
• and
• one or more memories including computer program code,
• the one or more memories and the computer program code configured to, with the one or more processors, cause the apparatus to perform at least the following:
• receiving information indicating one or more sets of reference signal patterns from a first transmission point, wherein at least one of the indicated one or more sets of reference signal patterns corresponds to one of one or more other transmission points;
• measuring the channel quality for the indicated one or more sets of reference signal patterns;
• and
• reporting indications of the measured channel quality for the indicated one or more sets of reference signal patterns to the first transmission point.

A computer program product comprising a computer-readable memory bearing computer program code embodied therein for use with a computer, the computer program code comprising:

• code for receiving information indicating one or more sets of reference signal patterns from a first transmission point, wherein at least one of the indicated one or more sets of reference signal patterns corresponds to one of one or more other transmission points;
• code for measuring the channel quality for the indicated one or more sets of reference signal patterns;
• and
• code for reporting indications of the measured channel quality for the indicated one or more sets of reference signal patterns to the first transmission point.

An apparatus, comprising

• one or more processors;

• the one or more memories and the computer program code configured to, with the one or more processors, cause the apparatus to perform at least the following:
• transmitting information indicating one or more sets of reference signal patterns from a first transmission point to a user equipment, wherein at least one of the indicated one or more sets of reference signal patterns corresponds to one of one or more other transmission points;
• and
• receiving from the user equipment indications of measured channel quality for the indicated one or more sets of reference signal patterns.
