摘要: A receiver apparatus wherein the processing amount for CQI (Channel Quality Indicator) measurements in a communication system having a plurality of system bandwidths can be reduced. In this apparatus, a narrow band CQI measurement part (109) measures, as a narrow band CQI, the CQI in resource blocks the number of which is required for the CQI measurement from the start position of a narrow bandwidth transmitted from a transmitter apparatus; a wide band CQI measurement part (110) extracts, from a system bandwidth transmitted from the transmitter apparatus, resource blocks the number of which is required for the CQI measurement, and then measures, as a wide band CQI representative of the channel quality of the whole system bandwidth, an average CQI in the extracted resource blocks; and a feedback information generating part (111) generates feedback information including both the narrow band CQI and the wide band CQI.

摘要: A method of transmitting data in a wireless communication system from a transmitter to a receiver, comprising the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitteds to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted to the receiver over a second diversity path. Finally, the received first and second data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodies to carry out the method of invention.
