The system provides: significantly enhanced mobile capability to the broadcast industry; an additional revenue source for the broadcast industry by dynamically selling available spectral resources for use by wireless broadband networks and/or broadcast content off-loaded from wireless broadband networks; additional spectrum for the broadband industry through the dynamic purchase of available spectrum; and an enriched user experience. A spectrum server may facilitate the dynamic allocation of radio spectrum made available by the broadcast networks. The broadcast networks may broadcast with enhanced waveform parameters to support mobile devices as well as fixed devices. ## Claims ### Claim 1 A system of wireless communications that enables base stations to request and receive additional downlink bandwidth to meet a high demand, the system comprising: a cellular network comprising a plurality of cellular base stations that communicate with and provide cellular services to user cellular devices, using cellular bandwidth and cellular uplinks and downlinks; and the cellular base stations configured to establish downlinks with the user cellular devices to provide the cellular services, using both cellular bandwidth and broadcast bandwidth; wherein the cellular base stations incorporate extensions that enable them to request and receive additional downlink bandwidth in a channel-allocated broadcast spectrum. ### Claim 2 (depends on 1) The system of claim 1, wherein the cellular base stations were originally configured to communicate via cellular bandwidth alone and have been reconfigured to establish downlinks with user cellular devices using both cellular bandwidth and broadcast bandwidth. ### Claim 3 (depends on 1) The system of claim 1, further comprising a broadcast spectrum exchange that provides the additional downlink bandwidth from one or more broadcast frequency bands to the cellular network. ### Claim 4 (depends on 3) The system of claim 3, wherein the broadcast exchange: aggregates available broadcast resources into contiguous bands to limit the number of radio receivers needed in the user cellular devices; and assigns available spectrum resources, when requested and/or as needed, to cellular base stations, enabling the user cellular devices to use the broadband spectrum to communicate. ### Claim 5 (depends on 4) The system of claim 4, wherein available spectrum resources are assigned in integer multiples of a fixed resource block (RB) bandwidth. ### Claim 6 (depends on 1) The system of claim 1, wherein the user cellular devices support communications using both LTE spectrum and VHF/UHF spectrum. ### Claim 7 (depends on 1) The system of claim 1, wherein the user cellular devices have physical layer extensions (PHY) that: support variable carrier spacing and variable delay spread tolerance; and use spectrum in integer multiples of a fixed resource block (RB) bandwidth of 180 kHz. ### Claim 8 (depends on 1) The system of claim 1, wherein the PHY supports variable carrier spacing and variable delay spread tolerance by using multiple symbol and cyclic prefix lengths, quantified by an integer number of symbols, including CPs, per 10 ms frame. ### Claim 9 (depends on 1) The system of claim 1, wherein the user cellular devices employ a software and hardware architecture that enables evolution over time. ### Claim 10 (depends on 1) The system of claim 1, wherein the user cellular devices incorporate a chipset that includes a programmable receiver, a programmable baseband processor, and a multicore application processor. ### Claim 11 (depends on 1) The system of claim 1, wherein the cellular base stations and user cellular devices are configured to provide a seamless downlink handoff, transparent to users, from cellular bandwidth to broadcast bandwidth and vice-versa. ### Claim 12 (depends on 1) The system of claim 1, wherein the cellular network pairs broadcast channels with LTE bands. ### Claim 13 A method for enabling base stations to request and receive additional bandwidth to meet a high demand, the method comprising: providing a cellular network comprising a plurality of wireless cellular base stations that were originally configured to communicate via cellular bandwidth alone, using uplinks and downlinks, which has been reconfigured to also communicate via broadcast bandwidth downlinks; monitoring available cellular bandwidth capacity and/or bandwidth demand at the base stations; providing broadcast bandwidth to base stations when requested and available; and sourcing the broadcast bandwidth from slices of aggregated broadcast carrier spectrum. ### Claim 14 (depends on 13) The method of claim 13, wherein the cellular base stations incorporate extensions that enable them to request and receive additional bandwidth in a broadband spectrum. ### Claim 15 (depends on 13) The method of claim 13, further comprising: combining a contiguous group of broadcast channels that are available to form a contiguous band; and assigning contiguous portions of the contiguous band to a wireless broadband network requesting such bandwidth. ### Claim 16 (depends on 13) The method of claim 13, further comprising aggregating available broadcast resources into contiguous bands to limit the number of radio receivers needed in the user cellular devices. ### Claim 17 (depends on 13) The method of claim 13, further comprising assigning available spectrum resources, when requested, to cellular base stations, enabling the user cellular devices to use the broadband spectrum to download content. ### Claim 18 (depends on 17) The method of claim 17, wherein the spectrum resources are assigned in integer multiples of a fixed resource block (RB) bandwidth, which itself is a function of one or more broadcast channel bandwidths. ### Claim 19 A method for enabling base stations to request and receive additional bandwidth to meet a high demand, the method comprising: providing a cellular network comprising a plurality of wireless cellular base stations that are configured to communicate via both cellular bandwidth, using uplinks and downlinks, and broadcast bandwidth, through downlinks; monitoring available cellular bandwidth capacity and/or bandwidth demand at the base stations; providing broadcast bandwidth to base stations when requested and available; and sourcing the broadcast bandwidth from slices of aggregated broadcast carrier spectrum. ### Claim 20 (depends on 19) The method of claim 19, further comprising assigning available spectrum resources, when requested, to cellular base stations, enabling the user cellular devices to use the broadband spectrum to download content.
