Grouping of users for MIMO transmission in a wireless communication system

A method comprising:

• classifying user equipments (UEs) into a plurality of groups comprising a first group and a second group, the first group including UEs to be scheduled individually for multiple-input multiple-output (MIMO) transmission, the second group including UEs to be scheduled together for MIMO transmission;
• interpreting channel quality indicator (CQI) information received from UEs classified in the first group in accordance with a first interpretation;
• and
• interpreting CQI information received from UEs classified in the second group in accordance with a second interpretation.

An apparatus comprising:

• means for classifying user equipments (UEs) into a plurality of groups comprising a first group and a second group, the first group including UEs to be scheduled individually for multiple-input multiple-output (MIMO) transmission, the second group including UEs to be scheduled together for MIMO transmission;
• means for interpreting channel quality indicator (CQI) information received from UEs classified in the first group in accordance with a first interpretation;
• and
• means for interpreting CQI information received from UEs classified in the second group in accordance with a second interpretation.
