Abstract: Techniques relating to generating and receiving radio frames with multiple partitions are disclosed. A mobile device may include a wireless radio, one or more antennas, and one or more processors. In some embodiments, the mobile device is configured to receive a frame of wireless data that includes a plurality of partitions and partition data. In some embodiments, the plurality of partitions each include multiple orthogonal frequency-division multiplexing (OFDM) symbols, and different ones of the partitions have different frequency transform sizes (e.g., different FFT sizes). In some embodiments, the partition data indicates the frequency transform sizes for the ones of the partitions. In some embodiments, the mobile device is configured to select, based on the partition data, one or more of the plurality of partitions and decode the selected one or more partitions to determine data represented by the OFDM symbols in the selected one or more partitions.

Abstract: In a next generation broadcast architecture, a broadcast gateway may send segments of a data file to a broadcast transmission system and to a server. The broadcast transmission system wirelessly transmits the segments to a user equipment (UE) device. When the UE device fails to decode a segment, it sends a request for re-transmission of the segment to the server via an IP network. The server re-transmits the requested segment to the UE device via the IP network. Furthermore, the gateway may receive one or more IP data flows (e.g., video streams) having variable bit rate. The gateway may apply dynamically-variable coding to the IP data flows so that the resulting coded IP data flows have an aggregate bit rate that matches a constant physical transport rate of the broadcast transmission system.

Abstract: A new television broadcast model called a Broadcast Market Exchange (BMX) eliminates the inefficiency in spectrum usage, providing maximum flexibility in delivering content through either VHF (for fixed location receiving devices) or UHF (optimized for mobile receiving devices) transmission/propagation. In conjunction with the BMX, a wireless communications system architecture is provided to enable a broadcast augmentation channel. The augmentation channel provides supplementation of the Quality of Service (QoS) of a one way User Datagram Protocol (UDP) delivery environment. The augmentation channel may be comprised of one or more physical delivery mechanisms (wired or wireless), but can be effectively unified for increasing QoS and or scalable levels of service (additional essence) to improve the user experience.
