Apparatus and methods for optimizing data transmission include receiving an indicator indicating the availability of a first communication channel, the first communication channel having a higher data rate than a second communication channel. Aspects can include determining whether the first communication channel is available to transmit data based on the indicator, and transmitting the data via the first communication channel, upon determining that the first communication channel is available. Additionally, aspects include entering a sleep state, upon determining that the first communication channel is not available, and determining whether the first communication channel has become available during a subsequent awake period. Entering a sleep state and determining whether the first communication channel has become available during a subsequent awake period may occur until the first communication channel becomes available or until an expiration of a timer. Other aspects, embodiments, and features are also claimed and described.
