US 9,072,094 B2 · Support for signaling over flexible bandwidth carrier

Abstract

Methods, systems, and devices are provided that may support signaling, such as a Signaling Radio Bearer (SRB), over a flexible bandwidth carrier. For example, an SRB rate for a SRB over for a normal bandwidth carrier may be identified. A Transmission Time Interval (TTI) may be determined for the SRB over for the flexible bandwidth carrier that facilitates a SRB rate of the SRB over the flexible bandwidth carrier that maintains at least the SRB rate for the SRB over the normal bandwidth carrier. The determined TTI may be utilized for the SRB over the flexible bandwidth carrier, which may help avoid increased call setup delay, increased latency for handover, etc. that may be introduced in flexible bandwidth carrier systems. Some embodiments may include reducing spreading factors, increasing transmission power, and/or concatenating multiple transport blocks with respect to the SRB over the flexible bandwidth carrier.
