Claim Text:
1. A method of allocating frequency resources on a shared spectrum utilized by a plurality of communication systems, the method comprising: acquiring, by circuitry of a radio apparatus, information indicating a frequency hopping pattern for control data in order to perform communication of the control data on at least one frequency resource unit hopping in frequency, wherein the frequency hopping pattern defines a control data band, comprising a plurality of frequency resource units, within the shared spectrum such that the control data occupies each of the frequency resource units at least once during a channel coherence time; acquiring information of a user data band defined as a function of the control data band according to a predetermined criterion in order to perform communication of user data on at least one free frequency resource unit within the user data band, wherein the user data band is within the shared spectrum and at least partly overlapping with the control data band; acquiring information of a total frequency band comprising the control data band and the user data band; and controlling, by the circuitry, communication of both the control data and the user data on the total frequency band.
