Embodiment Construction

[0030] figure 2 An exemplary OFDMA broadband communication system 42 comprising a base station (BTS) 44 and exemplary UEs 46, 47 and 48 is shown. The base station 44 includes a packet scheduler 50, transport channel processing blocks (indicated by reference numerals 52 and 54, respectively) for the SCCH and SDCH of each scheduled UE, transport and other channels, physical channel mapping block 56, inverse fast Fourier Transform (IFFT) processor 58 , cyclic prefix (CP) insertion block 60 , radio frequency block (FR) 61 and antenna 62 .

[0031] Each UE 46, 47 and 48 includes antenna 64, RF processing block 66, cyclic prefix removal block 68, fast Fourier transform (FFT) processor 70, physical channel de-mapping (de-map) block 72 for SCCH and SDCH The transmission processing blocks 74 and 76 and the CQI (Channel Quality Indication) measurement block 78 of .

[0032] The scheduling block 50 controls the overall resource allocation and data transmission to all UEs 46 , 47 and 4...

Abstract

In a wideband communication system including a transmitter and a plurality of mobile terminals (MT) that have maximum reception bandwidths, respectively, a Shared Control Channel (SCCH) for each MT is mapped so that physical channel symbols from the corresponding Physical Shared Control Channels (PSCCH) are confined to a block of consecutive sub-carriers defined by a smallest one of the maximum reception bandwidths.

Description

[0001] This application is a divisional application of an application that entered the national phase on July 18, 2008, with an application date of January 18, 2007, an application number of 200780002625.X, and an application titled "Methods for Physical Resource Management in Broadband Communication Systems" . technical field [0002] The present invention relates generally to broadband communication systems, and more particularly to methods of managing physical resources in such broadband communication systems. The invention is suitable for use in the management of a shared control channel for mobile terminals of different capabilities within an OFDMA network, and it is convenient to describe the invention in connection with this exemplary and non-limiting application. Background technique [0003] For convenience, terms adopted by 3GPP (3rd Generation Partnership Project), such as user equipment and UE, will be used throughout the detailed description of this specificatio...
