Abstract
A wireless communication system includes: a control module configured to calculate a maximum throughput to represent a spectral efficiency; a storage module, coupled to the control module, configured to store the maximum throughput in a throughput table; and a communication module, coupled to the control module, configured to transmit a channel quality indicator as a feedback, selected from the throughput table, based on a largest value of the maximum throughput.
Claims20
A wireless communication system comprising:
- a control module configured to:
- calculate a first throughput level based on modeling a communication process using automatic repeat request based on ignoring a channel in successive transmissions corresponding to the automatic repeat request;
- calculate a second throughput level based on modeling the channel across transmissions corresponding to the automatic repeat request;
- calculate a maximum throughput based on the first throughput level and the second throughput level to represent a spectral efficiency;
- a storage module, coupled to the control module, configured to store the maximum throughput in a throughput table;
- and
- a communication module, coupled to the control module, configured to transmit a channel quality indicator as a feedback, selected from the throughput table, based on a largest value of the maximum throughput.
A method of operation of a wireless communication system comprising:
- calculating a first throughput level based on modeling a communication process using automatic repeat request based on ignoring a channel in successive transmissions corresponding to the automatic repeat request;
- calculating a second throughput level based on a different process for modeling the communication process using the automatic repeat request;
- calculating a maximum throughput, representing a spectral efficiency, based on the first throughput level and the second throughput level, the maximum throughput level for each possible entry of a channel quality indicator;
- storing, in a throughput table, the maximum throughput;
- and
- selecting a channel quality indicator for transmitting a feedback, including accessing the throughput table for selecting the feedback having a largest value of the maximum throughput.
