Abstract
Aspects of the disclosure relate to a dynamic, configurable time division duplex (TDD) frame structure for hopping superframes utilized in narrowband Internet of Things (NB-IOT) wireless communication systems. The configurable frame structure includes an anchor segment residing on a plurality of anchor hopping frequencies and a data segment residing on one of a plurality of non-anchor hopping frequencies. The data segment includes a downlink portion, an uplink portion, and a configurable portion between the downlink control portion and the uplink control portion that may be configured to include at least one of downlink information or uplink information.
