Aspects described herein relate to configuring a discontinuous receive (DRX) mode in wireless communications. A transmission burst can be received over a communication frame, wherein the transmission burst includes a scheduling indication. A DRX OFF mode can be entered to suspend communication resources during at least an off period corresponding to a portion of a time period for the transmission burst based at least in part on the scheduling indication. A DRX ON mode can be entered to activate the communication resources during an on period corresponding to another portion of the time period subsequent to the off period defined for the transmission burst or a different time period subsequent to the time period defined for the transmission burst based at least in part on the scheduling indication.
