ENABLING COEXISTENCE BETWEEN INTELLIGENT TRANSPORTATION SYSTEM NETWORKS AND UNLICENSED WIRELESS LOCAL AREA NETWORKS

Abstract:

Certain aspects of the present disclosure provide techniques for enabling coexistence between intelligent transportation system (ITS) networks and unlicensed wireless local area networks (WLANs). A method that may be performed by an intelligent transportation system (ITS) device, includes transmitting one of a frame or a clear-to-send-to-self (CTS-to-self) message indicating a first time period during which a bandwidth will be in use, wherein the frame or CTS-to-self transmission is based on a first protocol; and transmitting, by the ITS device during the first time period and on the bandwidth, signaling, wherein the signaling is based on a second protocol.
