1. A method for transmitting channel quality information (CQI) by a mobile station (MS) in a communication system, the method comprising the steps of:
- receiving from a base station (BS) information of an allocation of a CQI channel and information as to a modulation to be performed on the CQI;
generating a CQI channel signal based on the CQI and the modulation information, the CQI corresponding to a measured channel state; and
transmitting the CQI channel signal to the BS over the allocated CQI channel.

Abstract
In transmitting channel quality information (CQI) by a mobile station (MS) in a communication system, the mobile station receives from a base station (BS) information of an allocation of a CQI channel and information as to a modulation to be performed on the CQI. CQI channel signal is generated based on the CQI and the modulation information, where the CQI corresponds to a measured channel state. The CQI channel signal is transmitted to the BS over the allocated CQI channel.

8. A mobile station for transmitting channel quality information (CQI), the mobile station comprising:
-
a channel generator to generate a CQI channel signal based on (i) the CQI corresponding to a measurement of a channel state, (ii) information of a channel allocation for transmission of the CQI, and (iii) information as to a modulation to be performed on the CQI, both the channel allocation information and the modulation information being received from a base station (BS); and
a transmitter to transmit the generated CQI channel signal to the BS over the allocated CQI channel. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A communication system for receiving channel quality information (CQI), the communication system comprising:
-
a receiver to receive from a mobile station (MS) a CQI channel signal on a CQI channel, the CQI channel being allocated to the MS and the CQI channel signal indicating the CQI as measured by the MS; and
a channel receiver to generate the CQI based on (i) a correlation performed on the CQI channel signal and (ii) information transmitted to the MS as to a modulation performed on the CQI by the MS in generating the CQI channel signal. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
