No. 60/912,661, filed Apr. 18, 2007, entitled �Base Station Synchronization For a Single Frequency Network�, Ser. No. 60/913,172, filed Apr. 20, 2007, entitled �Wireless Communications System With Broadcasting�, Ser. No. 60/953,452, filed Aug. 1, 2007, entitled �Base Stations Synchronization For a Single Frequency Network�, and Ser.

SUMMARY The present invention includes methods, apparatuses, and systems as described in the written description and claims. In one embodiment, a method of broadcasting content data in a macro-diversity region of a data frame is provided. This method comprises receiving a stream of transport packets, selecting at least one burst size, from amongst a set of a plurality of predetermined burst sizes, allocating one or more data bursts with the selected burst size to the macro-diversity region of the data frame, each data burst comprising at least a portion of the received transport packets and wherein the at least one burst size is selected so as to minimize a number of data bursts allocated to the macro-diversity region, and communicating information regarding the allocation of data bursts to the macro-diversity region for broadcasting a data frame comprising the macro-diversity region from at least a first transmitter.
Methods, apparatuses, and techniques are described for allocating data bursts to a macro-diversity region of a downlink communication signal transmitted from multiple base stations, or base transceiver stations, (BTS), such as, for example, BTSs in a single frequency network (SFN). As is known to those of skill in the art, a SFN refers to a network capable of simultaneously broadcasting the same signal (i.e., the same content) over the same frequency channel from multiple transmitters. Further, as used herein the term �macro-diversity region� refers to a portion of a data frame useable for broadcasting information. Exemplary macro-diversity regions include, for example, a Multicast and Broadcast Services (MBS) region of an Orthogonal Frequency Division Multiple Access (OFDMA) data frame, such as, for example, an OFDMA data frame in accordance with the Worldwide Interoperability for Microwave Access (WiMAX) standards (i.e., the Institute for Electrical and Electronics Engineers (IEEE) 802.16 Working Group on Broadband Wireless Access Standards). A further description of an exemplary macro-diversity region of a data frame is presented below. Further, as used herein the terms macro-diversity region and broadcast region are interchangeable.
In one embodiment, the output of the encapsulator module 116 is communicated to the single frequency network (SFN) adapter module 120 that receives the MPEG-2 transport packets and inserts time stamping information. In one embodiment, the packets outputted to the SFN adapter module 120 may be transmitted to the SFN adapter module 120 over a network, such as an Ethernet network. In one embodiment, the time stamping information added to the MPEG-2 transport packets enables individual BTSs 130 to be time synchronized to each other. The SFN adapter module 120 may further combine multiple received MPEG-2 transport packets into a larger frame (referred to herein as a �mega-frame�) for transmission by the BTSs 130. In one embodiment, the output of the SFN module 120 is communicated to the macro-diversity region control module 150 that receives the time stamped MPEG-2 data (e.g., the received MPEG-2 transport packets or mega-frame) and defines a macro-diversity region in a data frame. For example, the macro-diversity region defined can be a Multicast Broadcast Services (MBS) region of an OFDMA data frame, such as, for example, an OFDMA data frame in accordance with the WiMAX standards. A further description of the macro-diversity region is provided below.
The macro-diversity scheduler 406 can be implemented with a general purpose processor, a digital signal processor (�DSP�), an application specific integrated circuit (�ASIC�), a field programmable gate array (�FPGA�) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor can be a microprocessor, but in the alternative, the processor can be any processor, controller, microcontroller, or state machine. A processor can also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
