1. A system, comprising:
at least one memory that stores instructions; and
at least one processor that executes the instructions stored in the at least one memory, wherein the instructions cause the at least one processor to:
transmit, via a communication network, a registration request message to a first spectrum access system, the registration request comprising an access request for a first spectrum band, wherein the first spectrum band is wholly contained within a second spectrum band, and wherein the first spectrum access system is granted an access license for the second spectrum band from a second spectrum access system that is distinct from the first spectrum access system;
receive a registration response message, comprising a grant of access rights to the first spectrum band, from the first spectrum access system in response to the registration request message, wherein the first spectrum access system issues the grant of the access rights to the first spectrum band without exchanging any messages with the second spectrum access system; and
in response to receiving the grant of the access rights to the first spectrum band, establish, via the first spectrum band, a device-to-device communication link between a first user equipment at which the system operates and a second user equipment, wherein the device-to-device communication link does not traverse any radio access network elements of the communication network between the first user equipment and the second user equipment.
 
10. The system of claim 1, wherein:
the registration request message is a Citizens Broadband Radio Service (CBRS) Registration Request message that comprises the access request for the first spectrum band,
the registration response message is a CBRS Registration Response message that comprises the grant of the access rights, and
the device-to-device communication link is established without exchanging any other messages, other than the CBRS Registration Request message and the CBRS Registration Response message, with the first spectrum access system.
 
16. A non-transitory machine-readable medium comprising computer executable instructions that, when executed by at least one processor of first user equipment, facilitate performance of operations, the operations comprising:
transmitting, to a first spectrum access system via a communication network, a registration request message comprising an allocation request for a first spectrum band, wherein the first spectrum band is wholly contained within a second spectrum band, and wherein the first spectrum access system is granted access rights to the second spectrum band by a second spectrum access system that is distinct from the first spectrum access system;
receiving, from the first spectrum access system, a registration response message, comprising an allocation of the first spectrum band, in response to the registration request message, the allocation of the first spectrum band being issued by the first spectrum access system without exchanging any messages with the second spectrum access system; and
in response to receiving the allocation of the first spectrum band, establishing a direct communication link to a second user equipment via the first spectrum band, wherein the direct communication link does not traverse any radio access network elements of the communication network between the first user equipment and the second user equipment.
