Abstract:
1. A signal generator in a base station in an Orthogonal Frequency Division Multiplexing radio communication system which employs a plurality of sub-carriers, each sub-carrier belonging to one of a plurality of groups of sub-carriers, the signal generator receiving a sequence of numbers from a processor within the base station, each number in the sequence of numbers corresponding to one group of sub-carriers, the signal generator comprising: means for defining a set of acceptable groups of sub-carriers as all groups of sub-carriers for which the corresponding number has a value belonging to a first set of values; means for defining a set of unacceptable groups of sub-carriers as all groups of sub-carriers for which the corresponding number has a value belonging to a second set of values and; means for allocating for data transmission at one of at least one Link Mode the sub-carriers which belong to a group of sub-carriers within the set of acceptable groups of sub-carriers, a Link Mode being a set of at least one transmission parameter.
