High-speed data channel availability

摘要

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.

主权项

1. A method for optimizing data transmission, comprising:
receiving, at a UE, a message from a network node, wherein the message comprises an indicator indicating whether a supplemental first communication channel is available for transmitting data, the supplemental first communication channel having a higher data rate than a communication channel available for transmitting uplink data; determining whether the supplemental communication channel is available to transmit data based on the indicator in the message from the network; transmitting the data via the supplemental communication channel instead of the communication channel, upon determining that the supplemental communication channel is available; and entering a sleep state, upon determining that the supplemental communication channel is not available, and determining whether the supplemental communication channel has become available for transmitting data during a subsequent awake period at least in part by periodically monitoring the indicator in the message from the network node, wherein entering a sleep state and determining whether the supplemental communication channel has become available during a subsequent awake period occurs until the supplemental communication channel becomes available or until an expiration of a back-off timer.
