Patent ID: 8340586

Claim:
A method of link adaptation in a communications network, comprising: maintaining an error rate array in a storage component, wherein the error rate array has at least a channel condition value dimension and a transmission parameter dimension, wherein the channel condition value dimension is a set of channel condition values, wherein the transmission parameter dimension is a set of transmission parameters corresponding to data transmission capabilities of the communications network, wherein the error rate array includes at least four elements, and wherein each element corresponds to an error rate of a channel condition value/transmission parameter combination; receiving information reflecting a current condition of a communications channel; selecting a channel condition value of the set of channel condition values according to the received current condition of the communications channel; selecting at least one element of the error rate array corresponding to the selected channel condition value; selecting an individual transmission parameter of the set of transmission parameters, wherein the individual transmission parameter is selected based on the selected at least one element of the error rate array; and, transmitting data according to the selected individual transmission parameter.
