Split-spectrum grant request

A non-transitory computer-readable storage medium for use in conjunction with a radio node, the computer-readable storage medium storing program instructions that, when executed by the radio node, cause the radio node to perform operations comprising:

• determining a desired bandwidth in a shared-license-access band of frequencies, wherein the desired bandwidth is determined based at least in part on:
• a current capacity demand of the radio node, or an estimated capacity demand of the radio node;
• selecting two or more sub-spectra based at least in part on the desired bandwidth, wherein a sum of ranges of frequencies in the two or more sub-spectra equals the desired bandwidth, and a given sub-spectra in the two or more sub-spectra comprises a range of frequencies;
• providing, addressed to a computer, grant requests for the two or more sub-spectra, wherein a given grant request in the grant requests comprises a request to reserve a given one of the two or more sub-spectra to be used by the radio node, and a probability of approval of the given grant request is larger than a probability of a second grant request for the desired bandwidth;
• receiving grant responses associated with the computer, wherein the grant responses comprise approvals of grants for the two or more sub-spectra;
• providing, addressed to the computer, heartbeat requests to request authorization to transmit in the granted two or more sub-spectra;
• receiving heartbeat responses associated with the computer, wherein the heartbeat responses authorize the radio node to transmit in the granted two or more sub-spectra;
• and
• aggregating the two or more sub-spectra into a single aggregate channel, wherein the aggregation is performed by the radio node without further assistance of another electronic device or another radio node.

A method for providing grant requests, comprising:

• by a radio node:
• determining a desired bandwidth in a shared-license-access band of frequencies, wherein the desired bandwidth is determined based at least in part on:
• a current capacity demand of the radio node, or an estimated capacity demand of the radio node;
• selecting two or more sub-spectra based at least in part on the desired bandwidth, wherein a sum of ranges of frequencies in the two or more sub-spectra equals the desired bandwidth, and a given sub-spectra in the two or more sub-spectra comprises a range of frequencies;
• providing, addressed to a computer, grant requests for the two or more sub-spectra, wherein a given grant request in the grant requests comprises a request to reserve a given one of the two or more sub-spectra to be used by the radio node, and a probability of approval of the given grant request is larger than a probability of a second grant request for the desired bandwidth;
• receiving grant responses associated with the computer, wherein the grant responses comprise approvals of grants for the two or more sub-spectra;
• providing, addressed to the computer, heartbeat requests to request authorization to transmit in the granted two or more sub-spectra;
• receiving heartbeat responses associated with the computer, wherein the heartbeat responses authorize the radio node to transmit in the granted two or more sub-spectra;
• and
• aggregating the two or more sub-spectra into a single aggregate channel, wherein the aggregation is performed by the radio node without further assistance of another electronic device or another radio node.
