A portable protection apparatus includes a protective shield, a handle, a rechargeable battery, electrical circuitry configured to be powered by the rechargeable battery, and a first display element positioned on a first side of the protective shield. The first display element is configured to selectively display an instructional message when directed by the electrical circuitry, wherein the first display element is configured to be visible at a distance from the first side of the protective shield. The portable protection apparatus also includes a second display element positioned on a second side of the protective shield configured to display the instructional message to the user holding the protective shield.

A communication device is provided comprising a receiver configured to detect whether it can receive emergency notification information of a radio cell and, if it cannot receive the emergency notification information of the radio cell, search for another radio cell based on the possibility to receive emergency notification information of the other radio cell. Further, the communication device comprises a controller configured to, if the receiver has found another radio cell based on the possibility to receive emergency notification information of the other radio cell, initiate a reselection of the other radio cell.

Processing and transmitting transmission frames. A method for processing a transmission frame, includes receiving a transmission frame including a bootstrap portion, a preamble portion, and a payload portion. The boot strap portion of the received transmission frame is processed, by processing circuitry of a reception apparatus, to extract preamble structure information from one of four bootstrap symbols included in the bootstrap portion. The preamble portion of the transmission frame is decoded, by the processing circuitry, based on the extracted preamble structure information. A first one of the four bootstrap symbols is used for synchronization and a last one of the four bootstrap symbols in the bootstrap portion includes the preamble structure information. Further, the preamble structure information indicates a structure of one or more preamble symbols in the preamble portion that follows the last symbol.

Systems and methods are described, which prompt a UE that is receiving at least a physical layer signal from a broadcasting station to look for a new emergency alert. In embodiments, the UE renders content from the broadcasting station based on information received in transmitted physical layer frames. Included within a physical layer frame are bits, such as, ea_wake_up_bits. If the state change of the ea_wake_up_bits indicates that a new emergency message, referencing a new emergency alert, is being transmitted within the physical layer frame, the LTE locates the new emergency message within the physical layer frame and acts on the emergency message if it is applicable to the station to which the UE is tuned. If the emergency message is applicable, the UE acts on the emergency message by using information in the emergency message to locate and render the emergency alert. The emergency message may point to an EAS present on a linear TV service.

A plurality of auxiliary transmitters associated with at least one main transmitter, transmitting broadcast area wide programming for their respective broadcast areas, wherein a mechanism enables switching on transmission of localized auxiliary information content by at least one of the plurality of auxiliary transmitters, wherein the at least one of plurality of auxiliary transmitters transmits localized auxiliary information content on a single frequency network transmission frequency, and wherein the localized auxiliary information content includes a data item that enables retrieval of promotional information from a remote server, when the data item is analyzed by a software application.

A network node obtains (302) a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains (304) area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines (306) how many SIBs are needed for transmitting the area information and segments (308) the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits (310) the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.

Embodiments of this application provide example communication methods and apparatuses. One example method includes receiving a paging message from a network device, where the paging message includes first information, and the first information is used to indicate a resource location of a public warning system message. The public warning system message is received based on the paging message.
