Abstract
Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.
