Patent ID: 8849207

Claim:
In a system comprising a first communication device and a second communication device, a method performed by the first communication device for choosing a parameter setting from a set of two or more available parameter settings comprising a first available parameter setting and a second available parameter setting, wherein each of the first and second available parameter settings has an associated cost, the method comprising: (a) receiving, by the first communication device, an information transmitted by the second communication device, the information transmitted by the second communication device comprising parameter setting information identifying a parameter setting being used by the second communication device; (b) determining, by the first communication device, a first cost value based on the first available parameter setting and the parameter setting being used by the second communication device; (c) determining, by the first communication device, a second cost value based on the second available parameter setting and the parameter setting being used by the second communication device; (d) determining, using the first and second cost value, which available parameter setting, or settings, from the set of available parameter settings is associated with a lowest cost; (e) choosing, from the set of available parameter settings, the available parameter setting determined in step (d) or one of the available parameter settings determined in step (d) if more than one available parameter setting is associated with the lowest cost, wherein the step (d) comprises comparing a first total cost value of the first available parameter setting with a second total cost value of the second available parameter setting to determine whether the cost associated with the first available parameter setting is lower than the cost associated with the second available parameter setting, the first total cost value is the first cost value or is a value calculated using the first cost value and one or more other values, and the second total cost value is the second cost value or is a value calculated using the second cost value and one or more other values; and (f) transmitting, by the first communication device, an information identifying the parameter setting chosen in step (e) to the second communication device.
