Abstract
A method of reporting received signal quality to a transmitter includes measuring a received signal quality in a receiver, and selectively performing the steps of reporting the received signal quality to the transmitter, and reporting a selected modulation and coding scheme to the transmitter.
Claims17
A method for radio communications in which a receiver reports information used, to a transmitter, for a modulation and coding scheme control, said communication method comprising:
- measuring a received signal quality in the receiver;
- selecting which of the receiver or the transmitter performs a selection of the modulation and coding scheme based on the received signal quality;
- reporting the received signal quality to the transmitter when transformation of the received signal quality into a modulation and coding scheme is not conducted by the receiver;
- reporting a selected modulation and coding scheme to the transmitter when a selection of the modulation and coding scheme is conducted based on the received signal quality by the receiver;
- and
- receiving modulation and coding scheme information from the transmitter even if the receiver reports the modulation and coding scheme to the transmitter, the modulation and coding scheme information indicating which modulation and coding scheme is adapted to data transmission from the transmitter to the receiver.
