A system (1000) is disclosed including a resource allocation optimization (RAO) platform (1002) for optimizing the allocation of resources in network (1004) for delivery of assets to user equipment devices (UEDs) (1012). The RAO platform (1002) determines probabilities that certain asset delivery opportunities (ADOs) will occur within a selected time window and uses these probabilities together with information concerning values of asset delivery to determine an optimal use of asset deliveries. In this regard, the RAO platform (1004) received historical data from repository (1014) that facilitates calculation of probabilities that ADOs will occur. Such information may be compiled based on asset delivery records for similar network environments in the recent past or over time.

A receiver for receiving data in a broadcast system includes a broadcast receiver configured to receive, via the broadcast system, a receiver input data stream including a plurality of channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A redundancy unit selects or requests, if demodulation of a channel symbol and/or decoding of a codeword is erroneous or likely to fail, redundancy data for demodulation of future channel symbols and/or decoding of future codewords via a broadband system and a broadband receiver obtains the redundancy data via the broadband system. The demodulator and/or the decoder is configured to use the obtained redundancy data to demodulate the respective future channel symbols and to decode the respective future codewords, respectively.

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.

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.

A transmission method includes encoding processing that generates an encoded block, modulation processing that generates symbols from the encoded block, phase change processing that changes the phase of the symbols, and transmission processing that arranges the symbols in data carriers and transmits the symbols. The transmission processing configures a frame by arranging symbol groups in order in the frequency direction and transmits the frame. The symbol groups each include a symbol generated from a first encoded block and a symbol generated from a second encoded block. The phase change processing includes changing the phase of symbols the same symbol group using the same phase change value.

Large data transmission in digital radio broadcasting system and method are disclosed. A first channel information of tuned frequency indicates the availability of the data distribution table. Second channel information contains the data distribution info table (list of frequencies mapped to data chunk identifiers). Data chunks have a unique id. Digital broadcast radio receiver receives data distribution tables and parses through the currently tuned frequencies data distribution table. The receiver has information on how to collect the distributed data. Receiver uses its primary tuner to receive the data chunks in the current tuned frequency. Rest of the data chunks are collected by the background tuners in a parallel fashion by tuning to required frequencies. Once all chunks are collected, data file is reconstructed and available for presentation to the user.
