Technical Field

The technology discussed below relates to wireless communication systems, and more particularly to wireless communication devices capable of accessing licensed and unlicensed communication spectrum. Embodiments enable delivery of alert messages to wireless communication devices that may be out of coverage or may have limited access to communication connectivity.

Introduction to the design reside in

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple-access techniques capable of supporting communication with multiple users by sharing the available system resources. Examples of such multiple-access techniques include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

These multiple access techniques have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate on a city, country, region, and even global level. An example telecommunication standard is Long Term Evolution (LTE). LTE is an enhanced set of Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the third generation partnership project (3 GPP). LTE is designed to support mobile broadband access by improving spectral efficiency, reducing cost, and improving service using OFDMA on the downlink, SC-FDMA on the uplink, and multiple-input multiple-output (MIMO) antenna technology. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE technology. These improvements are also applicable to other multiple access techniques and telecommunications standards employing these techniques.

Various connectivity may be provided to a User Equipment (UE). When the UE is a vehicle, such as an automobile, the UE may be coupled to a cellular-type communication network, such as an LTE network or a 5G network, may be coupled to one or more other UEs over a vehicle-to-vehicle (V2V) network, such as a PC5 interface over a sidelink communication channel, may be coupled to a roadside unit (RSU) or another internet of vehicles (V2X) node over one or more communication channels, such as a cellular or sidelink communication channel, and may be coupled to other communication devices over, for example, a WiFi communication channel, a Dedicated Short Range Communication (DSRC) channel, a Wireless Wide Area Network (WWAN), a Wireless Local Area Network (WLAN), an integrated cellular internet of vehicles (CV2X)/LTE/5G communication channel, or another communication channel.

When a UE is only V2V capable (referred to as a mode 4 or autonomous UE), or when an LTE or 5G capable UE (referred to as a mode 3) may be outside the coverage of an LTE or 5G communication network, an emergency alert, such as a Commercial Mobile Alert Service (CMAS) communication, an Earthquake and Tsunami Warning System (ETWS) communication, or another alert message broadcast over the communication network, may not reach the mode 4UE or the out-of-coverage mode 3 UE.

Accordingly, it would be desirable to have the ability to forward such alerts to UEs that may otherwise be unable to receive the alert.
