Abstract: A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

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: 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.

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.

Abstract: A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN/NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX.
