Techniques for link adaptation for broadcast channels

A method for wireless communication at a network entity, comprising:

• transmitting a first downlink transmission to at least a first user equipment (UE);
• receiving a first uplink communication from the first UE, the first uplink communication providing a first channel quality indication of a measured channel quality of the first downlink transmission at the first UE, wherein the first channel quality indication indicates a measured channel quality of the first downlink transmission from a set of available channel quality indications that indicate different values of the measured channel quality;
• and
• transmitting a downlink broadcast transmission to the first user equipment and one or more other UEs, wherein the downlink broadcast transmission has one or more transmission parameters that are based at least in part on the first channel quality indication.

A user equipment (UE) for wireless communication, comprising:

• at least one processor;
• at least one memory coupled with the at least one processor;
• and
• instructions stored in the at least one memory and executable by the at least one processor to cause the UE to:
• receive a first downlink transmission from a network entity;
• transmit an uplink communication based at least in part on receiving the first downlink transmission, the uplink communication provides a channel quality indication that indicates a measured channel quality of the first downlink transmission from a set of available channel quality indications that indicate different values of the measured channel quality;
• and
• receive a downlink broadcast transmission, wherein the downlink broadcast transmission includes information for multiple UEs and is received in accordance with one or more transmission parameters that are based at least in part on the channel quality indication.
