Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support group channel quality indicator (CQI) reporting. For example, a user equipment (UE) may receive, from a base station, signaling indicating a group of component carriers (CCs) and one or more subbands within the group of CCs. The UE may receive one or more reference signals within the one or more subbands and determine a group CQI index corresponding to the group of CCs based at least in part on the one or more reference signals. The UE may then transmit a report to the base station indicating the group CQI index and the base station may determine a CQI index for each of the one or more subbands based on the group CQI index.
