Abstract
The present disclosure relates to a method of transmitting channel quality data for channels in a wireless communication system, and to a corresponding receiver and transmitter. In one embodiment, the method includes determining a plurality of channel quality indicators for a corresponding plurality of frequency intervals and transmitting information about channel quality indicators in the form of differentially encoded slope data.
Claims36
A method of transmitting channel quality data for channels in a wireless communication system comprising:
- determining a plurality of channel quality indicators for a corresponding plurality of frequency intervals;
- selecting at least one best channel quality indicator and its corresponding frequency interval;
- generating slope data relating to said at least one best channel quality indicator to the channel quality indicator of at least one adjacent frequency interval;
- and
- transmitting said at least one best channel quality indicator, an identifier of its frequency interval and said slope data.
A method of generating channel quality data for scheduling transmission in a wireless communication system comprising:
- receiving a best channel quality indicator, an identifier of its corresponding frequency interval and slope data relating said best channel quality indicator to the channel quality indicator of at least one adjacent frequency interval;
- and
- generating the channel quality indicator for the adjacent frequency interval using the best channel quality indicator and the slope data.
A receiver arranged to receive radio frequency signals via a wireless communication channel and adapted to transmit channel quality data to a transmitter of said signals, the receiver comprising:
- means for determining a plurality of channel quality indicators for a corresponding plurality of frequency intervals;
- means for selecting at least one best channel quality indicator and its corresponding frequency intervals;
- means for generating slope data relating said at least one best channel quality indicator to the channel quality indicator of at least one adjacent frequency intervals;
- and
- means for transmitting said at least one best channel quality indicator, an identifier of its corresponding frequency interval and said slope data.
A transmitter for transmitting radio frequency signals over a wireless communication channel, the transmitter comprising:
- means for receiving a best channel quality indicator, an identifier of its corresponding frequency interval and slope data relating said best channel quality indicator to the channel quality indicator of at least one adjacent frequency interval;
- means for generating a channel quality indicator for the adjacent frequency interval using the best channel quality indicator and the slope data;
- and
- scheduling means for scheduling said transmission based on the best channel quality indicator and/or the generated channel quality indicator.
A method for generating channel quality data for scheduling transmission in a wireless communication system, comprising:
- determining a plurality of channel quality indicators for a plurality of frequency intervals;
- and
- transmitting:
- a channel quality indicator value for at least one selected frequency interval;
- the channel quality indicator for all other frequency intervals, each transmitted differentially with respect to the channel quality indicator of an adjacent frequency interval.
A method for scheduling transmission in a wireless communication system, comprising:
- receiving channel quality indicator information comprising:
- at least one individual channel quality indicator value for selected frequency intervals;
- and
- the channel quality indicator for all other frequency intervals, each transmitted differentially with respect to the channel quality indicator of an adjacent frequency interval;
- and
- scheduling transmission based on the received channel quality indicator information.
A receiver arranged to receive radio frequency signals via a wireless communication channel and adapted to transmit channel quality data to a transmitter of said signals, the receiver comprising:
- means for determining a plurality of channel quality indicators for a plurality of frequency intervals;
- and
- means for transmitting:
- a channel quality indicator value for at least one selected frequency interval;
- the channel quality indicator for all other frequency intervals, each transmitted differentially with respect to the channel quality indicator of an adjacent frequency interval.
A transmitter for transmitting radio frequency signals over a wireless communication channel, the transmitter comprising:
- means for receiving channel quality indicator information comprising:
- at least one individual channel quality indicator value for selected frequency intervals;
- and
- the channel quality indicator for all other frequency intervals, each transmitted differentially with respect to the channel quality indicator of an adjacent frequency intervals;
- and
- means for scheduling transmission based on the received channel quality indicator information.
