Abstract

The present disclosure discusses devices, methods, and systems for improving signaling. This can occur, according to some implementations, by increasing a power of at least one signaling channel if errors on the signaling channel occur, comprising tracking quality of the at least one signaling channel, determining whether the at least one signaling channel has an error rate that is above a threshold, and increasing power to the at least one signaling channel if the error rate is above the threshold. Other aspects, embodiments, and features are also claimed and described.
