Patent ID: 8300716

Claim:
A method of adaptively selecting a modulation and coding scheme (MCS) of a communication link, the method comprising: obtaining a first parameter corresponding to a Quality of Service (QoS) requirement of the communication link; obtaining a second parameter indicative of a physical condition of the communication link, wherein obtaining the second parameter includes estimating an instantaneous value of Carrier-to-Interference-plus-Noise Ratio (CINR) according to a formula: η CINR_dB ⁡ [ k ] = 10 ⁢ ⁢ log 10 ⁡ ( 10 μ CINR_dB ⁡ [ k ] / 10 - α · 10 σ CINR_dB ⁡ [ k ] / 10 ) , wherein μ CINR — dB [k] is a mean of a plurality of CINR measurements in decibels at a time k, σ CINR — dB [k] is a standard deviation of the plurality of CINR measurements at the time k, and α is a coefficient to select a degree of confidence of estimating the instantaneous value of CINR; and selecting an MCS as a function of at least the first parameter, the second parameter, and a given packet length.
