Device and methods for managing channel allocation in CBRS

A citizens broadband radio service (CBRS) device (CBSD) comprising:

• a transceiver;
• and
• a processor operatively connected with the transceiver, the processor configured to:
• determine priorities of a plurality of non-contiguous channels in a CBRS band based on a bandwidth and a power required by the CBSD;
• generate a grant request message including information on an identity of the CBSD, information on an array of operation parameter sets corresponding to the plurality of non-contiguous channels, and information on a number of grants requested by the CBSD for the plurality of non-contiguous channels, wherein each of the operation parameter sets in the array includes a frequency range and a maximum equivalent isotropic radiated power (EIRP), and wherein the operation parameter sets are listed in an order of the priorities in the array;
• send the grant request message to a spectrum access system (SAS);
• and
• receive, from the SAS, a grant response message for indicating channels granted by the SAS from among the plurality of non-contiguous channels, wherein a number of the channels granted by the SAS corresponds to the number of grants requested by the CBSD.
