Abstract

Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.
