OPEN-LOOP RATE CONTROL FOR A TDD COMMUNICATION SYSTEM

摘要

A method for wireless communications, comprising receiving, via a second communication link, feedback for packets sent in a first data transmission via a first communication link; estimating signal-to-noise-and-interference ratio (SNR) of the first communication link based on an estimated SNR of the second communication link, an asymmetric parameter indicating a difference in channel quality between the first and second communication links, and at least one back-off factor used to used to reduce the SNR estimate from an average SNR; adjusting at least one back-off factor based on the received feedback; and selecting a rate for a second data transmission based on the estimated channel quality of the first communication link as well as a corresponding apparatus.
