摘要： 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.

摘要： Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different target geographic areas. A data frame may include a first partition that includes a physical layer encoding of first data to be transmitted in a first geographic area, where the first geographic area is defined by a first threshold distance from the one or more transmitters. The data frame may include a second that includes a physical layer encoding of second data to be transmitted in a second geographic area, where the second geographic area is defined by a second, greater threshold distance from the one or more transmitters.

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 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).

摘要： Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different encoding schemes. An apparatus may include one or more processing elements configured to receive, via a wireless radio, wireless data that includes a plurality of portions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols. Different ones of the portions have different frequency transform sizes and different sampling rates. The wireless data may also include control data that indicates the frequency transform sizes and sampling rates for the ones of the portions. The apparatus may select, based on the control data and a determined velocity of the apparatus, one or more but not all of the plurality of portions and may decode the selected one or more portions to determine data represented by the OFDM symbols in the selected one or more portions. Different portions of the wireless data may be adapted for decoding by devices moving at different maximum velocities.
