Abstract: In order to facilitate communication in a shared-license-access band of frequencies, an electronic device (such as an electronic device that implements a spectrum allocation service) allocates, to a radio node in a set of radio nodes, at least a first channel and a second channel in unallocated channels in the shared-license-access band of frequencies. Note that the first channel and the second channel are noncontiguous in the shared-license-access band of frequencies. Then, the electronic device monitors for transmissions by a higher-priority user than the set of radio nodes in the shared-license-access band of frequencies. When the transmissions are detected in the first channel, the electronic device instructs the radio node to discontinue use of the first channel, where allocation of at least the second channel allows uninterrupted communication by the radio node in the shared-license-access band of frequencies.
