Abstract

Techniques for controlling parameters for uplink transmission associated with a device to facilitate improving a communication condition metric(s) (CCM(s)) of the uplink transmission are presented. A communication management component (CMC) can determine whether CCM satisfies a first threshold CCM. If CCM does not, CMC can modify a parameter(s) to reduce a number of resource blocks or an MCS value to improve the CCM. If respective minimum threshold levels have been reached for the number of resource blocks and MCS value, and CCM still is not satisfying the first threshold CCM, CMC can modify a parameter to increase an amount of repetition of data packets for uplink transmission (unless a maximum threshold amount of repetition is reached). If CCM satisfies an applicable threshold CCM for a defined amount of time, CMC can modify parameters to increase the number of resource blocks, increase MCS value, or reduce repetition of data packets.
