Method for allocating a subchannel in an orthogonal frequency division multiple access cellular communication system
First Claim
1. A method for allocating a subchannel by a transmitter in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system in which an entire frequency band includes a plurality of bands, each of the plurality of bands includes a plurality of bins, and each of the plurality of bins includes a plurality of subcarriers, the method comprising:
- selecting, by the transmitter, any one of the plurality of bands in an Adaptive Modulation and Coding (AMC) subchannel time interval;
selecting, by the transmitter, a predetermined number of bins among the plurality of bins in the selected band; and
allocating, by the transmitter, the selected bins as an AMC subchannel,wherein a predetermined time interval is divided into the AMC subchannel time interval and a diversity subchannel time interval.

Abstract
A method for allocating a subchannel in a transmitter of an Orthogonal Frequency Division Multiple Access (OFDMA) cellular communication system in which an entire frequency band includes a plurality of bands, each of the bands includes a plurality of bins, and each of the bins includes a plurality of subcarriers. The method includes dividing a predetermined time interval into an Adaptive Modulation and Coding (AMC) subchannel time interval and a diversity subchannel time interval; selecting any one of the plurality of bands in the AMC subchannel time interval; selecting a predetermined number of bins among the plurality of bins in the selected band; and allocating the selected bins to the AMC subchannel.

9. A method for allocating a subchannel by a transmitter in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system in which an entire frequency band includes a plurality of bands, each of the plurality of bands includes a plurality of bins, and each of the plurality of bins includes a plurality of subcarriers, the method comprising:
-
allocating, by the transmitter, an Adaptive Modulation and Coding (AMC) subchannel in an AMC subchannel time interval; and allocating, by the transmitter, a diversity subchannel in a diversity subchannel time interval, wherein a predetermined time interval is divided into the AMC subchannel time interval and the diversity subchannel time interval, and wherein allocating the diversity subchannel comprises; selecting any one of the subcarriers in each of a plurality of groups; and allocating the selected subcarrier as the diversity subchannel, wherein the frequency band is divided into the plurality of groups in the diversity subchannel time interval. - View Dependent Claims (10, 11, 12, 13)
