One such event can include a current signal-to-noise-ratio, e.g., as reported in a channel quality indicator report from a user equipment. Another such event can comprise a number of consecutive hybrid automatic repeat request acknowledgments or negative acknowledgments (HARQ ACKS/NACKS), in which consecutive ACKs tend to indicate good signal quality, while consecutive NACKs tend to indicate poor signal quality. A combination of channel quality indicator-based adaptive repetition level and HARQ ACK/NACK-based adaptive repetition level can be employed. ## Claims ### Claim 1 A method, comprising: configuring, by network equipment comprising a processor, a user equipment with a first repetition level, wherein the first repetition level is applicable to repetition of a data block communicated between the user equipment and the network equipment for a transmission of the data block;
