Wireless communication rate shaping

摘要

Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The transition probabilities are adjusted to encourage transitions in a desired direction. In one embodiment, the transition probabilities are adjusted as a function of the FL Signal to Interference and Noise Ratio Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. In another embodiment, the transition probabilities are adjusted as a function of the historical loading condition of the system. In still another embodiment, the transition probabilities are adjusted as a function of differences in rise-over-thermal values between neighboring sectors.
