A gateway application in a content engine multiplexes requests for real-time content to servers that, in turn, service the requests by streaming appropriate real-time content to requesting users. A software communication port of the content engine may be reserved to receive request messages from multiple client computers, at least two of which request streaming of real-time content according to different selected formats. After identifying client properties (e.g., a format for which to receive streaming real-time content) associated with the requests for real-time content, the gateway application identifies corresponding servers of the content engine to serve the real-time content according to the different selected formats. The gateway application forwards the requests for streaming of real-time content associated with the request messages to the corresponding servers which, in turn, satisfy the requests by streaming the requested real-time content to the client computers.

Field programmable gate arrays (FPGA's) may be structured in accordance with the disclosure to have a register-intensive architecture that provides, for each of plural function-spawning LookUp Tables (e.g. a 4-input, base LUT's) within a logic block, a plurality of in-block accessible registers. A register-feeding multiplexer means may be provided for allowing each of the plural registers to equivalently capture and store a result signal output by the corresponding, base LUT of the plural registers. Registerable, primary and secondary feedthroughs may be provided for each base LUT so that locally-acquired input signals of the LUT may be fed-through to the corresponding, in-block registers for register-recovery purposes without fully consuming (wasting) the lookup resources of the associated, base LUT. A multi-stage, input switch matrix (ISM) may be further provided for acquiring and routing input signals from adjacent, block-interconnect lines (AIL's) and / or block-intra-connect lines (e.g., FB's) to the base LUT's and / or their respective, registerable feedthroughs. Techniques are disclosed for utilizing the many in-block registers and / or the registerable feedthroughs and / or the multi-stage ISM's for efficiently implementing various circuit designs by appropriately configuring such register-intensive FPGA's.

The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and / or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and / or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs

Disclosed is a method for allocating and accessing downlink resources in the OFDMA communication system. In the resource allocation method, bursts having the same modulation and channel encoding level are arranged in a predetermined temporal order on a physical layer. Information on the allocated unit resources is included in a common control block and is transmitted to a subscriber station, and the subscriber station then detects a number of the allocated unit resources to thus check the range of bursts to be received by the subscriber station. Therefore, power consumption by the subscriber station is reduced and signaling overheads of the common control information and unneeded residual resources are decreased.
