摘要： Systems and methods for relaying in broadcast single-frequency networks are disclosed herein. A single-frequency network can be formed in part using transmitters that receive data via a cooperative relay channel instead of a station-to-transmitter link. In some embodiments, a second channel may use a portion of its transmission time to relay the information to the single-frequency network transmitter using time-division multiplexing. In other embodiments, a second channel may encode the relayed information on a second layer using layer-division multiplexing.

摘要： Systems and methods are provided for communication ultra-high definition (UHD) video. At the transmitter-side, a single packet stream that includes packets corresponding to a plurality of encoded content streams may be generated, and the single packet stream may be split into a plurality of sub-streams. The splitting may include grouping packets corresponding to the single packet stream into a plurality of chunks, each associated with a respective one of the sub-streams; adding handling related information to each of the chunks; and incorporating into at least one packet in a first one of the sub-streams at least some of handling related information associated with a second one of the sub-steams. The sub-streams may then be processed for transmission over a particular physical medium. At the receiver-side, the signals may be received and processed, and the sub-streams may be reconstructed based on processing of the plurality signals.

摘要： Implementations relate to prioritized data transmission features over networks. A method can include deriving description data from content data. The description data describes content of the content data and includes one or more portions corresponding to one or more portions of the content data. The description data is transmitted to a destination over a network to be made accessible over the network at the destination to one or more users. The content data also is transmitted to the destination to be made accessible. At least one portion of the description data finishes transmitting and is made accessible before its corresponding portion of the content information finishes transmitting and is made accessible.

摘要： Systems and methods for future-proofed control signaling are disclosed herein. A waveform enabling broadcast transmission of physical layer frames having variable parameters can be extended to allow for future additions to the control signaling structure without breaking compatibility with existing receivers. In some embodiments, new signaling parameters can be added in an existing portion of a preamble and the length of the modified parameter set can be indicated to legacy receivers. In some embodiments new signaling parameters can be added at the end of the existing preamble and viewed as reserved bits by legacy receivers.

摘要： A cooperative communication method includes determining bandwidth of a first wireless network that user equipment (UE) currently accesses, determining bandwidth required by data to be sent to the UE, and when the bandwidth of the first wireless network cannot meet the bandwidth required by the to-be-sent data, sending a first part of data packets to the first wireless network, and sending a second part of the data packets to at least one core network, so that the at least one core network sends the second part of the data packets to the UE using at least one wireless network, where a communications protocol of the first wireless network is different from that of the at least one wireless network. Bandwidth resources can be integrated on wireless networks with different communications protocols, so that fluent transmission of data can be implemented.
